Understanding Coma: A State of Prolonged Unconsciousness

A coma is a profound state of unconsciousness where an individual is unresponsive to their environment. Despite appearing to be in a deep sleep, a person in a coma cannot be awakened by any form of stimulation, including pain. This condition results from brain injury, which can be temporary and reversible or, in some cases, permanent.

What exactly happens in the brain during a coma? The brain’s normal functioning is disrupted, affecting the Reticular Activating System (RAS), which is responsible for arousal and awareness. This disruption can occur due to various factors, including increased pressure, bleeding, oxygen deprivation, or toxin buildup in the brain.

Common Causes of Coma: From Trauma to Metabolic Disturbances

Comas can result from a wide range of causes, with over 50% of cases linked to head trauma or disturbances in the brain’s circulatory system. Some of the primary causes include:

• Traumatic brain injury
• Stroke
• Oxygen deprivation (hypoxia or anoxia)
• Infections affecting the central nervous system
• Metabolic imbalances
• Toxic exposure
• Prolonged seizures

How does trauma lead to a coma? When the brain experiences severe trauma, it can swell or bleed. This swelling pushes against the skull, potentially damaging the RAS and other crucial brain structures, leading to a loss of consciousness and coma.

Anoxic Brain Injury: A Silent Threat

Anoxic brain injury, caused by a complete lack of oxygen to the brain, is a particularly severe form of brain damage that can result in coma. Even a few minutes without oxygen can cause irreversible cell death in brain tissues. This type of injury can occur due to various circumstances, including:

• Cardiac arrest
• Severe head trauma
• Drowning incidents
• Drug overdoses
• Poisoning

Metabolic Disturbances and Coma

Can metabolic issues cause a coma? Indeed, they can. Metabolic disturbances, particularly in individuals with diabetes, can lead to coma-inducing conditions. Both extremely high blood sugar (hyperglycemia) and critically low blood sugar (hypoglycemia) can result in a coma. While these types of comas are often reversible once blood sugar levels are corrected, prolonged hypoglycemia can cause permanent brain damage and persistent coma.

Types of Coma: Varying Degrees of Unconsciousness

Not all comas are the same. There are several types of coma, each with its own characteristics and prognosis:

1. Toxic-metabolic encephalopathy
2. Persistent vegetative state
3. Medically induced coma

What distinguishes these types of coma? Let’s explore each one in detail.

Toxic-Metabolic Encephalopathy

This acute condition of brain dysfunction is characterized by confusion and/or delirium. It’s usually reversible and can be caused by various factors, including systemic illness, infection, organ failure, and other conditions. The key feature of this type of coma is its potential for reversal with appropriate treatment.

Persistent Vegetative State

A persistent vegetative state represents a severe form of unconsciousness where the individual is unaware of their surroundings and incapable of voluntary movement. In this state, a person may progress to wakefulness but without higher brain function. Despite the lack of awareness, basic functions such as breathing, circulation, and sleep-wake cycles are maintained.

Medically Induced Coma

How does a medically induced coma differ from other types? This is a temporary state of unconsciousness intentionally created by medical professionals to protect the brain from swelling after an injury and allow the body to heal. It involves administering a controlled dose of anesthetic to the patient, causing a lack of feeling or awareness. This procedure is performed only in hospital intensive care units under close medical supervision.

Treatment Approaches for Coma: Addressing the Underlying Cause

The treatment for a coma largely depends on its underlying cause. Prompt medical attention is crucial to address potentially reversible conditions. What are some common treatment approaches for coma?

• Treating infections with antibiotics
• Addressing metabolic imbalances
• Managing intracranial pressure
• Providing supportive care
• Implementing rehabilitation strategies

Why is early intervention so crucial in coma treatment? Early and appropriate intervention can significantly impact the outcome, potentially preventing further brain damage and improving the chances of recovery.

After-Effects of Coma: Navigating the Road to Recovery

The journey doesn’t end when a person emerges from a coma. Many individuals experience various after-effects that can persist for weeks, months, or even years. What are some common after-effects of coma?

• Physical disabilities
• Cognitive impairments
• Emotional and behavioral changes
• Sensory disturbances
• Communication difficulties

How do these after-effects impact daily life? The severity and duration of these effects can vary greatly depending on the cause and duration of the coma, as well as the areas of the brain affected. Some individuals may experience minor issues that resolve quickly, while others may face long-term challenges requiring ongoing support and rehabilitation.

Physical Rehabilitation: Regaining Function and Independence

Physical rehabilitation plays a crucial role in recovery from coma. It aims to help individuals regain lost functions and relearn basic skills. What does physical rehabilitation typically involve?

• Physical therapy to improve strength and mobility
• Occupational therapy to enhance daily living skills
• Speech therapy to address communication issues
• Cognitive rehabilitation to improve mental functions

How long does rehabilitation typically last? The duration of rehabilitation can vary significantly, ranging from weeks to years, depending on the individual’s condition and progress.

Cognitive and Emotional Recovery: Rebuilding Mental Capacities

Cognitive and emotional recovery are often challenging aspects of post-coma rehabilitation. Many individuals experience changes in their thinking abilities, memory, and emotional responses. How can these challenges be addressed?

• Cognitive behavioral therapy
• Memory training exercises
• Emotional support and counseling
• Medication management for mood disorders

Is full cognitive recovery possible after a coma? While some individuals may experience complete cognitive recovery, others may have lasting impairments. The extent of recovery often depends on the severity and location of the brain injury, as well as the duration of the coma.

Long-Term Prognosis: Factors Influencing Recovery

The long-term prognosis for individuals who have experienced a coma can vary widely. What factors influence the likelihood of recovery?

• Cause of the coma
• Duration of unconsciousness
• Age and overall health of the patient
• Extent of brain damage
• Quality and timeliness of medical care
• Access to comprehensive rehabilitation services

Can someone fully recover from a coma? While some individuals do make a full recovery, especially from brief, medically induced comas, others may experience lasting effects. It’s important to note that recovery is often a gradual process, and improvements can continue for months or even years after the initial injury.

Minimally Conscious State: A Step Towards Recovery

For some individuals, the journey from coma to full consciousness involves a transitional phase known as the minimally conscious state. What characterizes this state?

• Intermittent periods of awareness and responsiveness
• Ability to follow simple commands
• Purposeful movements
• Emotional responses to stimuli

How does the minimally conscious state differ from a vegetative state? Unlike a vegetative state, individuals in a minimally conscious state show clear, albeit inconsistent, signs of awareness of themselves and their environment. This state often represents a positive step in the recovery process.

Supporting Coma Patients and Their Families: A Multifaceted Approach

The impact of a coma extends beyond the patient to their family and caregivers. What support systems are crucial for coma patients and their families?

• Medical support teams
• Psychological counseling
• Support groups
• Social services
• Financial advisors

How can families cope with the uncertainty of coma recovery? Coping strategies may include:

• Educating themselves about the condition
• Maintaining open communication with medical professionals
• Seeking emotional support
• Participating in the patient’s care when appropriate
• Practicing self-care and stress management

The Role of Family in Recovery

Family involvement can play a significant role in the recovery process of coma patients. How can family members contribute to the recovery process?

• Providing familiar stimuli (e.g., voices, music)
• Participating in therapy sessions
• Assisting with daily care routines
• Advocating for the patient’s needs
• Offering emotional support and encouragement

Does family involvement improve outcomes for coma patients? While more research is needed, many healthcare professionals believe that family involvement can have a positive impact on recovery, potentially improving cognitive function and emotional well-being.

Advances in Coma Research: Paving the Way for Better Outcomes

Ongoing research in neuroscience and medicine continues to enhance our understanding of coma and improve treatment strategies. What are some promising areas of coma research?

• Brain stimulation techniques
• Neuroimaging advancements
• Biomarker identification for prognosis
• Novel pharmacological interventions
• Brain-computer interfaces

How might these research areas impact future coma treatment? These advancements could potentially lead to more accurate prognoses, targeted treatments, and improved rehabilitation strategies, ultimately enhancing recovery outcomes for coma patients.

Ethical Considerations in Coma Care

The care of coma patients often involves complex ethical considerations. What are some of the key ethical issues in coma care?

• End-of-life decision-making
• Resource allocation in long-term care
• Informed consent for treatment and research
• Quality of life assessments
• Balancing hope with realistic expectations

How do healthcare professionals navigate these ethical challenges? It often involves a multidisciplinary approach, including input from medical ethicists, legal experts, and family members, always prioritizing the best interests of the patient.

Prevention Strategies: Reducing the Risk of Coma-Inducing Injuries

While not all causes of coma are preventable, certain strategies can reduce the risk of coma-inducing injuries. What are some key prevention strategies?

• Wearing protective gear during high-risk activities
• Practicing safe driving habits
• Managing chronic health conditions effectively
• Avoiding substance abuse
• Maintaining a healthy lifestyle

How effective are these prevention strategies? While they cannot eliminate all risks, these strategies can significantly reduce the likelihood of traumatic brain injuries and other conditions that may lead to coma.

Public Education and Awareness

Raising public awareness about coma and its causes is crucial for prevention and early intervention. What role does public education play in coma prevention and care?

• Increasing knowledge about risk factors
• Promoting safety measures
• Encouraging prompt medical attention for potential brain injuries
• Reducing stigma associated with coma and brain injury
• Fostering community support for affected individuals and families

How can public awareness campaigns be most effective? Successful campaigns often combine factual information with personal stories, utilize various media platforms, and partner with healthcare providers and community organizations to reach a wide audience.

A coma is a prolonged state of unconsciousness. During a coma, a person is unresponsive to their environment. The person is alive and looks like they are sleeping. However, unlike in a deep sleep, the person cannot be awakened by any stimulation, including pain.

Comas are caused by an injury to the brain. Brain injury can be due to increased pressure, bleeding, loss of oxygen, or buildup of toxins. The injury can be temporary and reversible. It also can be permanent.

More than 50% of comas are related to head trauma or disturbances in the brain’s circulatory system. Problems that can lead to coma include:

• Anoxic brain injury. This is a brain condition caused by total lack of oxygen to the brain. Lack of oxygen for a few minutes causes cell death to brain tissues. Anoxic brain injury may result from heart attack (cardiac arrest), head injury or trauma, drowning, drug overdose, or poisoning.
• Trauma: Head injuries can cause the brain to swell and/or bleed. When the brain swells as a result of trauma, the fluid pushes up against the skull. The swelling may eventually cause the brain to push down on the brain stem, which can damage the RAS (Reticular Activating System) — a part of the brain that’s responsible for arousal and awareness.
• Swelling: Swelling of brain tissue can occur even without distress. Sometimes a lack of oxygen, electrolyte imbalance, or hormones can cause swelling.
• Bleeding: Bleeding in the layers of the brain may cause coma due to swelling and compression on the injured side of the brain. This compression causes the brain to shift, causing damage to the brainstem and the RAS (mentioned above). High blood pressure, ruptured cerebral aneurysms, and tumors are non-traumatic causes of bleeding in the brain.
• Stroke: When there is no blood flow to a major part of the brain or loss of blood accompanied with swelling, coma can occur.
• Blood sugar: In people with diabetes, coma can occur when blood sugar levels stay very high. That’s a condition known as hyperglycemia. Hypoglycemia, or blood sugar that’s too low, can also lead to a coma. This type of coma is usually reversible once the blood sugar is corrected. However, prolonged hypoglycemia can lead to permanent brain damage and persistent coma.
• Oxygen deprivation: Oxygen is essential for brain function. Cardiac arrest causes a sudden cutoff of blood flow and oxygen to the brain, called hypoxia or anoxia. After cardiopulmonary resuscitation (CPR), survivors of cardiac arrest are often in comas. Oxygen deprivation can also occur with drowning or choking.
• Infection: Infections of the central nervous system, such as meningitis or encephalitis, can also cause coma.
• Toxins: Substances that are normally found in the body can accumulate to toxic levels if the body fails to dispose of them correctly. As an example, ammonia due to liver disease, carbon dioxide from a severe asthma attack, or urea from kidney failure can accumulate to toxic levels in the body. Drugs and alcohol in large quantities can also disrupt neuron functioning in the brain.
• Seizures: A single seizure rarely produces coma. But continuous seizures — called status epilepticus — can. Repeated seizures can prevent the brain from recovering in between seizures. This will cause prolonged unconsciousness and coma.

Types of coma can include:

• Toxic-metabolic encephalopathy. This is an acute condition of brain dysfunction with symptoms of confusion and/or delirium. The condition is usually reversible. The causes of toxic-metabolic encephalopathy are varied. They include systemic illness, infection, organ failure, and other conditions.
• Persistent vegetative state. This is a state of severe unconsciousness. The person is unaware of their surroundings and incapable of voluntary movement. With a persistent vegetative state, someone may progress to wakefulness but with no higher brain function. With persistent vegetative state, there is breathing, circulation, and sleep-wake cycles.
• Medically induced: This type of temporary coma, or deep state of unconsciousness, is used to protect the brain from swelling after an injury – and allow the body to heal. The patient receives a controlled dose of an anesthetic, which causes lack of feeling or awareness. Doctors then closely watch the person’s vitals. This happens only in hospital intensive care units.

Treatment for a coma depends on the cause. People close to the comatose patient should give doctors as much information as possible to help the doctors determine the cause of coma. Prompt medical attention is vital to treat potentially reversible conditions. For example, if there is an infection that’s affecting the brain, antibiotics may be needed. Glucose may be required in the event of a diabetic shock. Surgery may also be necessary to relieve the pressure on the brain due to swelling or to remove a tumor.

Certain drugs may also help relieve the swelling. Medication may also be given to stop seizures if necessary.

In general, treatment for a coma is supportive. People in comas are looked after in an intensive care unit and may often require full life support until their situation improves.

The prognosis for a coma varies with each situation. The chances of a person’s recovery depend on the cause of the coma, whether the problem can be corrected, and the duration of the coma. If the problem can be resolved, the person can often return to their original level of functioning. Sometimes, though, if the brain damage is severe, a person may be permanently disabled or never regain consciousness.

Comas that result from drug poisonings have a high rate of recovery if prompt medical attention is received. Comas that result from head injuries tend to have a higher rate of recovery than comas related to lack of oxygen.

It can be very difficult to predict recovery when a person is a coma. Every person is different and it is best to consult with your doctor. As we would expect, the longer a person is in a coma, the worse the prognosis. Even so, many patients can wake up after many weeks in a coma. However, they may have significant disabilities.

Artificial coma – what is it, why is it used, how is it introduced and withdrawn, and what can be the predictions and consequences of this procedure. Find out all the details in our article.

In modern medicine, artificial coma is a unique treatment that allows you to restore brain function and bring the patient back to life. However, few people know what it is and what are the consequences on the human body.

Artificial coma is a technique in which the patient is put into a special state of unconsciousness when the brain stops functioning. This is done in order to protect the brain from damage and provide it with rest. For this, special medications are used that stop the brain from working.

However, like any medical method, artificial coma has its advantages and disadvantages. The patient may be in a coma for several days or even weeks. At the same time, his body is severely depleted, which can lead to complications. In addition, the patient may not retire to fully recover from the procedure and be left with severe consequences.

Artificial coma: definition and symptoms

Artificial coma is a condition where the patient is in a deep sleep caused by special medications. It is used to treat severe brain diseases, reduce swelling and repair damaged tissues.

Signs of this condition are lack of motor skills, suppressed cough and swallow reflex, low blood pressure, low heart rate, which helps reduce the brain’s metabolic demand for oxygen and nutrients.

Artificial coma is a powerful tool in the treatment of severe forms of brain diseases. However, it should be remembered that it can cause serious side effects, such as cardiac arrhythmias, lung damage, as well as lead to reduced nutrition and deterioration in general condition.

Artificial coma: what is it?

An induced coma is a condition caused by special drugs used to put the patient to sleep. This is a temporary state that allows the brain to rest and recover from injury or other serious illness.

The procedure for the introduction of an artificial coma is carried out in a special department of the hospital with constant medical supervision.

Signs and symptoms of the need to induce coma

Serious head injury

Induction of an induced coma may be necessary in the event of a serious head injury such as a concussion, hemorrhage, or severe bruising. Signs that indicate the need to enter an artificial coma may include loss of consciousness, severe headache, difficulty breathing, impaired vision and hearing, and loss of coordination.

Cardiac or respiratory arrest

Induction of induced coma may also be required in case of cardiac or respiratory arrest. This can be caused by a variety of things, including a heart attack, choking, or anaphylactic shock. Symptoms that indicate the need to enter an artificial coma may include permanent brain damage, loss of consciousness, and lack of response to external stimuli.

Brain tumor

Induction of an artificial coma may also be necessary in the case of a brain tumor. This can occur as a result of a malignant tumor or metastases from other types of cancer. Signs that indicate the need for an induced coma may include headache, nausea, vomiting, visual and hearing disturbances, and changes in behavior and mood.

Introduction of artificial coma: principles and methods

Medical indications

An artificial coma is a state in which the patient is deliberately disconnected from life and placed in a special state in order to undergo treatment. It can be used for various diseases: head trauma, stroke, severe convulsions. The duration of an artificial coma depends on many factors, and each case is individual.

Introduction principles

Introduction into an artificial coma occurs through a special technique. After that, the patient is in a special room controlled by medical personnel, where he is provided with medical care.

Methods of withdrawal

The patient is brought out of the artificial coma gradually to avoid a number of complications. Medical staff gradually reduce the dose of anesthetics, while continuing to monitor the patient’s condition. When a patient is brought out of an artificial coma, it is important to monitor some recovery parameters: oxygen in the blood, blood pressure.

Proactive measures can prevent possible complications and make the recovery process faster and more efficient. The recovery period after an artificial coma depends on many factors, such as the duration of the coma, internal diseases, and age.

How an artificial coma is administered

An artificial coma is a methodological tool used in medicine to care for severely injured patients.

Introduction of artificial coma is a process that is carried out only in specialized medical institutions and for certain indications. This is an extremely complex and responsible procedure, in which it is necessary to control the patient’s condition and his functions.

In order to carry out the introduction of an artificial coma, specialists of medical institutions collect all the necessary information about the patient and perform several additional diagnostic tests. After that, doctors can decide on the need for an artificial coma.

The decision to initiate an artificial coma is taken only after careful discussion and analysis of the situation. This can be the only salvation for the patient, since it allows you to reduce the load on the body and give the body the opportunity to recover on its own.

A well-planned and well-executed introduction of an artificial coma improves the chances of recovery of the patient in addition to the necessary treatment of his underlying disease.

Principles for the introduction of artificial coma

Artificial coma is a treatment that involves the patient being given special drugs to put him or her into a restless state where the brain cannot function normally. This may be required in the event of a head injury, stroke, or other conditions where the brain needs rest.

The process of introducing an artificial coma depends on the reason for its use. For a stroke, for example, the patient may be given medication to lower blood pressure and reduce stress on the brain. Barbiturates are used for head injury victims who may experience mental depression.

Recovery from induced coma may also vary depending on the reason for its use. When the patient has already responded to external stimuli, he can simply be withdrawn through the interruption of drug support. In other cases, the patient may require switchover procedures to bring him or her out of the coma smoothly.

Various uses of artificial coma

Artificial coma is a special medical condition in which the patient is kept for a long time. Its use is necessary in cases of severe brain injury, stroke, poisoning and other conditions when it is necessary to reduce brain activity and prevent the development of consequences. There are several ways to introduce an artificial coma.

• Administration of sedatives. With this method, the patient’s consciousness is clouded and he falls asleep.
• Anesthesia administration. This method is used in severe analgesic procedures to relieve the patient of pain.
• Administration of barbiturates. This is the most powerful way to induce induced coma. It is used only in extreme cases when the patient is in a critical condition.

Recovery from artificial coma is gradual. As a rule, the first step is to reduce the dose of drugs, after which the patient begins to wake up. However, the recovery process from an artificial coma can be lengthy and requires careful medical supervision.

Although the use of induced coma is necessary in some cases, it can also cause a number of significant effects, such as changes in brain activity, impaired blood circulation, and other physical problems. In addition, the patient may experience psychological difficulties such as loss of coordination and memory, anxiety and depression. Therefore, it is very important that the decision to use artificial coma be taken after careful consideration, and the process of induction and withdrawal from it should be carried out under the close supervision of qualified specialists.

How to get out of an artificial coma

An artificial coma can be used for medical purposes to temporarily free the brain from functional activity. As a rule, after reaching the goal, the patient is taken out of an artificial coma.

To bring a patient out of an artificial coma, specialists gradually reduce the doses of anesthetics and provide the patient with everything necessary for his recovery. In this process, it is extremely important to control the indicators of pressure, pulse and oxygen levels in the blood.

When a patient begins to regain consciousness from an induced coma, physical and psychological rehabilitation measures may be required. These measures help him regain skills lost while in a coma, strengthen his muscles, and improve his visual and auditory functions.

Waking up from an induced coma is a complex but necessary process for a patient’s recovery. With the right approach, he can return the full functions of his life and return to its normal rhythm.

Signs and possibilities of recovery from an artificial coma

An artificial coma can last indefinitely, which causes concern among the patient’s relatives. There are a number of signs that may indicate that recovery from an artificial coma is becoming possible.

1. Reaction to painful stimuli. If the patient begins to react to painful stimuli, this may indicate that consciousness begins to clear up and recovery from the coma is possible.
2. Appearance of response to sound stimuli. If the patient begins to respond to sound stimuli, this may indicate the restoration of nervous activity.
3. Improved respiratory function. If the patient begins to breathe spontaneously or needs less artificial breathing support, this may indicate an improvement in his condition.

Various methods can be used to wake up from an artificial coma, depending on the cause of the coma and its duration. One of the most common methods is progressive reduction in the dose of medications that caused the coma. This method helps to gradually restore consciousness and nervous activity.

If the cause of the coma is a head injury or brain tumor, surgery may be required to remove the tumor or repair other damage. In some cases, long-term rehabilitation may be needed to restore the full functionality of the body and restore the patient’s quality of life.

Methods of withdrawal from artificial coma

Medical withdrawal

One of the methods of withdrawal from artificial coma is medical. This means the use of special drugs that help wake the patient and bring him out of the coma.

Medical withdrawal from induced coma can be lengthy and require constant monitoring of the patient’s condition. In addition, this method may be accompanied by various side effects, such as dizziness, nausea, vomiting, and other symptoms.

Stimulation of the nervous system

Another method of bringing out of artificial coma is the stimulation of the nervous system. To do this, the patient may be given various electrical impulses or other stimulation methods that help awaken the brain and bring the patient out of unconsciousness.

This method is usually used in cases where drug withdrawal is ineffective. However, this method is also not without risks and can lead to various complications, such as pain and disorders of the nervous system.

Surgical method

The surgical method of bringing out of artificial coma is used in extreme cases when other methods are ineffective. Usually, this method is used in cases where it is necessary to quickly eliminate the cause of the coma, for example, to remove a tumor or hemorrhage.

Surgical recovery from artificial coma can be very effective, but is also not safe and can lead to various complications such as infection and bleeding.

Consequences of artificial coma

Physical consequences

An artificial coma is a procedure in which the patient is put into a drug-induced sleep. This can lead to a number of physical consequences, including decreased muscle strength and loss of coordination. In addition, prolonged time in a coma can lead to weakened bones and the development of ulcers caused by pressure on the limbs.

Psychological effects

Artificial coma can affect the patient’s emotional state, causing post-traumatic stress syndrome, depression and anxiety. Patients may experience anxiety and uncertainty about what is happening around them as they cannot perceive the environment while in a coma. In addition, recovery from an artificial coma can take a long time, which can also cause emotional discomfort.

Prognosis

Prognosis depends on the injury or disease that caused the need for induced coma and how long the patient has been in this state. In some cases, recovery may take several weeks, while in other cases, the patient will need long-term treatment. In addition, complications may occur as a result of the procedure, such as infections or damage to internal organs.

Conclusion

An induced coma is a serious medical procedure that may be necessary in some cases. However, it can cause a number of physical and psychological consequences for the patient. The prognosis depends on the specific situation, and, as a rule, a long time is needed for recovery.

Effects of induced coma

An induced coma is a procedure in which the patient’s brain function is suppressed to prevent damage and pain until doctors deal with a fatal disease or injury. However, the patient may experience negative effects such as:

• Memory and cognitive problems: The patient may experience memory problems and other cognitive problems after coming out of the induced coma. These problems may be temporary or permanent.
• Muscle weakness: The patient may experience muscle weakness after an induced coma, especially if he has been comatose for an extended period of time. In these cases, physical rehabilitation may allow the patient to return to normal life again.
• Speech problems: The patient may experience problems with his speech after an artificial coma. These problems may include difficulty in pronouncing words and forming correct phrases. Speech specialists can help the patient during rehabilitation after an artificial coma.

Consequences: What to do:

9028 5 Physical rehabilitation

It should be noted that the effects of induced coma may be temporary or permanent and may vary depending on many factors. For best results, it is important that the patient receives qualified medical care both before and after the coma.

Rehabilitation of patients after recovery from an artificial coma

After an artificial coma, the patient needs a long rehabilitation. This is due to the fact that brain activity after such a state is often in a disturbed state.

The main task of the rehabilitation period is to restore brain functions. This is achieved by conducting special classes with a speech therapist, psychotherapist and ergotherapist.

Physiotherapy is also an important part of rehabilitation work. It is aimed at improving the functioning of joints and muscles, as well as restoring movement. An important stage of physiotherapy is the rehabilitation of the muscles of the mouth and throat, which in turn contributes to the restoration of speech and nutrition through the mouth.

In addition, psychological support is an important aspect of rehabilitation. After an artificial coma, the patient may experience psychological problems such as depression and anxiety. Therefore, at this stage, it is important to provide the patient with psychological and emotional support.

The total recovery time after an artificial coma can take several months. It is important to remember that each patient is unique and his individual characteristics should be taken into account when choosing a rehabilitation program.

Q&A:

What is artificial coma?

Artificial coma is a condition that medical professionals induce by suppressing the patient’s consciousness with drugs to treat or improve health outcomes.

What is an artificial coma for?

Artificial coma may be used to reduce metabolism and oxygen demand in survivors of traumatic or neurological injury, for medical procedures, to prevent recurrence or subsequent injury, and to treat epilepsy and certain other conditions.

How is artificial coma administered?

Artificial coma is administered by medical professionals by intravenous administration of drugs such as barbiturates or propofol.

How is one brought out of an artificial coma?

Withdrawal from artificial coma occurs gradually by reducing the dose of drugs. When the dose reaches a low level, the patient begins to gradually regain consciousness, which may take several hours.

What are the prognosis after artificial coma?

Prognosis after induced coma depends on the reason for which it was caused. If an induced coma is used to treat head or skull trauma, the prognosis may be better; if an induced coma is used to treat other conditions such as epilepsy, the prognosis may be less favorable.

What are the possible consequences after an artificial coma?

Consequences after induced coma may include prolonged unconsciousness, impaired learning and memory, impaired muscle coordination, and reduced intelligence. However, the consequences may be related to the reason the induced coma was induced, and not directly to the induced coma itself.

Is there life after a coma?

Neurosurgeons and neuroresuscitators give a chance to survive to many of those who Fifteen years ago he was doomed to die immediately

Olga Dobromyslova

Coma

– Sergey Vasilievich, people often come to you in a state of coma. But there are other states that are similar to a coma only externally. For example, a lethargic dream. Although its nature is probably quite different.

– Indeed, a lethargic dream is not a coma, but a protracted psychogenic reaction. At first glance, she looks like a coma. However, there are two or three relatively simple neurological tests by which any neuroresuscitator will distinguish him from a coma.

– Will he distinguish, but will not be able to help?

– It’s not his part. We need a psychiatrist here. It is necessary to introduce a neuroleptic – and the patient will come to his senses for a while. Then he needs to be treated with psychotropic drugs.

– Can a person sleep in this way for a long time outside the field of view of doctors?

– Can’t. It must at least be watered and fed through a gastric tube or intravenous catheter. Otherwise, the person will die within a week.

– What other reasons can cause a coma?

– Coma can occur in the course of an infectious disease, in particular meningitis. Sometimes, you know, diabetic coma. Coma often accompanies cerebral stroke and traumatic brain injury.

Work for the Brain

– Given the recent number of strokes and injuries, the cause you serve is extremely important. How would you define its essence?

-The ideology of salvation is simple: start helping immediately. And this immediacy does not consist in introducing some kind of saving fast-acting medicine, but in ensuring an adequate supply of oxygen to the patient’s brain. Only in this way can his defeat be stopped.

Patients come to us, as a rule, in a coma. In a coma, the patient most often breathes normally. But the function of the brain is so affected that the normal amount of oxygen in the blood is not enough for it. A larger amount is provided only by artificial ventilation of the lungs. One of the features of neuroresuscitation is that artificial ventilation treats not only the affected lungs, but also the brain!

Another task of resuscitators is to increase blood flow to the brain. To do this, the patient is injected with liquid as aggressively as oxygen. In addition, intensively increase blood pressure with drugs. All this is done with one goal: to ensure the flow of oxygen-rich blood to the brain. But we all know what high blood pressure can do to the brain. So there is a risk. The resuscitator has to “play on the verge of a foul.” But there is no other way, otherwise the patient cannot be saved.

Artificial ventilation of the lungs is carried out using special devices. The first in our country was created back in the 60s especially for Academician Landau, who was in a car accident. His students and friends copied and improved the Swedish Engstrem apparatus. This “RO” apparatus of ours was recognized in the 1960s as the best in the world. Unfortunately, little has changed since then. And many clinics are still equipped with such devices.

– What devices do you use?

– Our clinic is now well equipped. Artificial ventilation devices are so “smart” that they independently adjust to the rhythm of the patient’s breathing and supply him with oxygen at the very moment when he takes a breath.

– It turns out that effective neuroresuscitation is carried out only in your department?

15 – 20 years ago, 60 – 70 percent of patients died from severe traumatic brain injury. Today – 30 – 35 percent

– Not only. There are specialized neuroresuscitation units in Moscow at the Burdenko Institute of Neurosurgery, in St. Petersburg at the Military Medical Academy and at the Polenov Institute of Neurosurgery. In addition, there are clinics in large cities where effective neuroresuscitation care is provided by general intensive care units. But a common misfortune throughout Russia is the low saturation of control and diagnostic equipment: there are few devices for performing computed tomography of the brain, magnetic resonance imaging. Without them, the state of the brain is difficult to assess. But it is so important to know where the blood has accumulated, on which parts of the brain it presses, where the brain is shifting, how effective the therapeutic actions are. It is on this information that the neurosurgeon’s tactics are based. And the sooner he receives this information, the greater the likelihood of a positive outcome of the operation. Both in trauma and stroke, brain cells die quickly, and as a result, even if the patient survives, his quality of life is greatly reduced. At best, an arm or leg is immobilized, and at worst, intelligence or memory is reduced.

– You say: procrastination is like death. It turns out that the ambulance should intervene aggressively. Are the machines equipped for this task?

– Unfortunately, in practice this can only be done by a special team – an intensive care team. There are many of them in Moscow, but still not enough. Therefore, now we are striving to ensure that each ambulance team is prepared to carry out a complex of resuscitation measures and is appropriately equipped. Its task is to deliver the patient to the hospital as soon as possible, providing an enhanced supply of blood and oxygen to his brain along the way. Need to reorganize and emergency hospitals. Our institute is an example of a modern emergency center: we have all round-the-clock diagnostic services, operating rooms, intensive care units. Although there are also enough problems, and not the last – the lack of personnel. Too hard work, too low wages…

After the operation, it is also important to use the entire arsenal of means for monitoring the patient’s condition that is currently available. Based on the modern requirements of science, a neurosurgeon inserts a special sensor inside the skull during the operation to constantly monitor the dynamics of the patient’s brain edema in the postoperative period. But due to the lack of equipment, only a few specialized centers regularly practice this technique. Also important is information about the sufficiency of oxygen saturation of the brain, the state and work of the heart. This data is also monitored continuously. On the monitor at the head of the patient – all the information that allows you to provide adequate assistance to the operated patient.

– And it helps to avoid complications?

– If the patient was treated in this way at all stages, there is hope that many of the problems usually associated with a stroke or brain injury will bypass him. Otherwise, it will take longer to recover. And this means that he is longer in intensive care.

Hole in the skull

– What other treatments are used to treat a brain injury?

– During some neurosurgical interventions, for example, for craniocerebral injuries, the brain swells very much in the postoperative period, and the volume of the skull seems to be not enough for it. This swelling can last long enough, and the consequences can be serious. To reduce the resulting pressure on the brain from the side of the skull, the surgeon sometimes removes part of the bone and sews it between the muscles of the patient’s thigh.

– Why?

– To be taken out and put back in place.

– Is the thigh used as a storage room? And nothing happens with this piece?

– This piece is perfectly preserved in the muscles of the thigh, except that it is slightly reduced in size. But this is immaterial. Later, sewn into place in the skull, it works as a base for tissue growth. The bone begins to grow later – from the periphery to the center.

– And how long does this piece of bone lie in the thigh?

– From a month to six months.

– And all this time the patient walks with a hole in his head?

– This is acceptable. It is important to avoid direct injury to an unprotected area. By the way, native bone is not always used to heal a skull defect. Sometimes they put a titanium or plastic plate, it then grows with its own bone tissue.

– Everything you said seems to be top notch. That is not typical for the whole country. Or is the death rate from craniocerebral injuries decreasing across the country? Are there any statistics on such deaths?

– It is the statistics that show that in the country the results of medical intervention for traumatic brain injuries are changing for the better. 15 – 20 years ago, 60 – 70 percent of patients died from severe traumatic brain injury. Today – 30 – 35 percent, in the best clinics – 20, and among children it is 10 – 12. lives can be saved. And how much more can be saved with sufficient equipment of diagnostic and monitoring equipment and medicines.

– Are survivors fully restored?

– If out of 10 victims 8 survive, then out of these 8 5 – 6 return to work. But something in them still changes. As a rule, memory decreases, the ability to learn, emotional disorders may begin. True, we had a patient from alcoholics. Before the injury, he was aggressive, and after discharge, according to his wife, he became so calm and kind. But most patients, even those who are quite kind in life, usually come out of a coma through a state of aggression.

– How long does it take?

– Various. More often a few days. But if, for example, the frontal lobes of the brain are injured, the state of aggression can last for several weeks. Moreover, aggression is so strong that it is necessary to fix arms and legs with special devices so that a person does not injure himself. However, patients do not remember this later. They generally do not remember their stay in the intensive care unit, even if they were conscious and were able to communicate with doctors and relatives. This is a defensive reaction of the brain – it prefers to spend the minimum energy that it has on recovery, and nothing else.

Vegetative state

– How long can a person be in a coma?

– It is believed that if within a month the brain has not recovered to such an extent that it is able to perceive this world, it means that some serious changes have occurred in it.

– And there is no way to bring him out of the coma?

– Strictly speaking, no “anti-comic” drugs have yet been invented. This does not mean that there are no promising drugs. But, unfortunately, the effects of most of the drugs proposed to date have not yet received sufficient clinical confirmation. All the efforts of doctors are reduced to preserving the largest possible number of brain cells in a coma and creating conditions for it to still begin to function. The art of neuro-resuscitation is to most successfully replace temporarily lost brain functions at all stages of resuscitation.

– And if this doesn’t happen in a month?

– Then we qualify his condition as vegetative. Journalists dubbed such people “vegetables.” Doctors consider the use of this term unethical. In such patients, most of the functions of the body are preserved, they can open their eyes, make some slight movements, but are not able to contact the outside world.

– And is it irreversible?

– Some of those in the vegetative state are slowly but surely coming out of it. Sometimes specially designed measures to increase the external flow of information help – they talk to the patient, turn on music, take them out to the balcony or street. If at the same time nothing changes within three months, the prognosis is very poor. Theoretically, if such a patient is fed, watered, provided with sanitation of the lungs, protected from bedsores, he can live indefinitely, but only in the conditions of intensive care units.

It would be better for these people to have special institutions, as in many other countries. In our country, they lie “over the state”, that is, there are no additional staff units for their treatment. Therefore, the staff does not have time to pay enough attention to them, trying first of all to save newly admitted emergency patients, because they are in greater danger. This does not improve the life prognosis of those in a vegetative state at all.

And some people live like this for a year, two, ten. But what next? In my opinion, the fate of such patients should be decided by relatives. And document your decision. As it is done in America, in England, and in half of Europe too. If their will is to save a loved one from further suffering, he is disconnected from all devices. To avoid pain, narcotic analgesics are administered. And the patient dies quietly.

We have such a scenario – an unaffordable luxury. The doctor, seeing that the patient is hopeless, might decide to stop supporting his life, but in this case he will inevitably break the law.

– Yes, you can’t envy this patient.

– But there is another category of patients who are not to be envied. These are those for whom to live or not to live depends entirely on whether you are lucky with a donor organ or not. And there are a huge number of them. Much more than the number of donors.

– And who can act as donors?

– These may be patients who have recorded brain death (legally, it is equated to the death of the body). As well as patients with irreversible cardiac arrest. Unfortunately, the legal framework in this area is very contradictory in our country. In particular, according to the law on transplantation, in our country there is a so-called presumption of consent. The meaning of this concept is that any citizen who has not expressed a direct refusal to be a transplant donor is a potential donor. At the same time, according to the law on the funeral business, any person who has taken the trouble to bury the deceased may refuse to open the body.

Lately, the media has been fanning stories about doctors selling livers and hearts abroad from people who are still alive. Some stupidity. The procedure for ascertaining brain death is so transparent that even a non-specialist can check it. After ascertaining brain death, another 6 hours pass until it is legally possible to take the organs. During this time, any verification is possible. Unfortunately, when taking organs from patients with irreversible cardiac arrest, such a check cannot be carried out: to lose time before transplantation – the recipient’s organs will not take root! However, here, too, the mechanism for ascertaining death is unequivocal.

But in trying to help a patient in need of an organ donor, a doctor runs the risk of being imprisoned. Although in the whole civilized world the problem has long ceased to be a problem. Everyone decides for himself in advance whether it will be possible after death to use his organs for transplanting them to those in need or not.
