What is sepsis and how does it develop. Who is at risk for sepsis. What are the signs and symptoms of sepsis. How is sepsis treated and prevented.

Defining Sepsis: A Critical Medical Condition

Sepsis is a severe and potentially life-threatening medical emergency that occurs when the body’s response to infection spirals out of control. It is characterized by a chain reaction throughout the body triggered by an existing infection. This extreme response can rapidly lead to tissue damage, organ failure, and death if not promptly treated.

The gravity of sepsis is underscored by alarming statistics:

• At least 1.7 million adults in America develop sepsis annually.
• Approximately 350,000 adults who develop sepsis die during hospitalization or are discharged to hospice.
• One in three people who die in a hospital had sepsis during that hospitalization.
• In nearly 87% of cases, sepsis or the infection causing it starts before a patient is admitted to the hospital.

The Origins and Progression of Sepsis

Sepsis typically begins with an infection that triggers an overwhelming immune response. The most common sites where infections leading to sepsis originate include:

• Lungs
• Urinary tract
• Skin
• Gastrointestinal tract

While bacterial infections are the most frequent cause of sepsis, viral infections such as COVID-19 or influenza, and fungal infections can also lead to this condition.

Is sepsis contagious?

Sepsis itself is not contagious. However, the infections that can lead to sepsis may be transmissible. It’s crucial to understand that while you cannot directly spread sepsis to others, you can potentially spread the underlying infection that could result in sepsis in another person.

Identifying High-Risk Groups for Sepsis

Although sepsis can affect anyone, certain groups are at higher risk:

• Adults aged 65 or older
• Individuals with weakened immune systems
• People with chronic medical conditions such as diabetes, lung disease, cancer, and kidney disease
• Those who have recently experienced severe illness or hospitalization
• Survivors of previous sepsis episodes
• Children younger than one year old

Cancer and Sepsis Risk

Cancer patients face an elevated risk of sepsis due to the nature of the disease and its treatments. Chemotherapy, while effective against cancer cells, also diminishes the body’s infection-fighting white blood cells. This condition, known as neutropenia, is a common side effect of chemotherapy that increases susceptibility to infections and, consequently, sepsis.

Recognizing the Signs and Symptoms of Sepsis

Early detection of sepsis is crucial for effective treatment. The signs and symptoms of sepsis can include:

• High heart rate or weak pulse
• Confusion or disorientation
• Extreme pain or discomfort
• Fever, shivering, or feeling very cold
• Shortness of breath
• Clammy or sweaty skin

It’s important to note that a medical assessment by a healthcare professional is necessary to confirm sepsis. If you suspect sepsis in yourself or a loved one, seeking immediate medical attention is crucial.

Immediate Actions for Suspected Sepsis

Sepsis is a medical emergency that requires swift action. If you or someone you know has an infection that’s not improving or is worsening, follow these steps:

1. Seek medical care immediately.
2. Ask your healthcare provider, “Could this infection be leading to sepsis?”
3. Inquire if you should go to the emergency room.
4. In case of a medical emergency, call 911 and inform the operator if you suspect sepsis or have COVID-19.
5. If possible, wear a mask before medical help arrives.

Remember, rapid recognition and treatment significantly increase survival rates. Treatment typically involves urgent medical care in an intensive care unit, careful monitoring of vital signs, and often the administration of antibiotics.

Preventive Measures and Risk Reduction

While it’s not always possible to prevent sepsis, there are steps you can take to reduce your risk, especially if you’re in a high-risk group:

• Practice good hygiene, particularly hand washing
• Keep cuts clean and covered until healed
• Manage chronic conditions effectively
• Get vaccinated against preventable infections
• Seek prompt medical care for infections

Specific Precautions for Cancer Patients

Cancer patients undergoing chemotherapy should take additional precautions to prevent infections:

• Wash hands frequently and ask others to do the same
• Avoid crowded places and sick individuals
• Discuss vaccinations with your doctor, including flu shots
• Maintain daily hygiene, including bathing and dental care
• Use unscented lotion to prevent dry or cracked skin
• Use a soft toothbrush and mouthwash to prevent mouth sores

The Importance of Timely Intervention in Sepsis Cases

The critical nature of sepsis cannot be overstated. Timely intervention is paramount in managing this condition effectively. Healthcare professionals employ a range of strategies to combat sepsis, including:

• Rapid administration of broad-spectrum antibiotics
• Intravenous fluids to maintain blood pressure and organ function
• Oxygen therapy to support breathing
• Medications to support blood pressure
• In severe cases, dialysis or mechanical ventilation may be necessary

The “golden hour” concept in sepsis treatment emphasizes the importance of initiating appropriate therapy within the first hour of recognition. This rapid response can significantly improve outcomes and reduce mortality rates.

How does early intervention impact sepsis outcomes?

Early intervention in sepsis cases can dramatically improve patient outcomes. Studies have shown that for every hour delay in administering appropriate antibiotics, the risk of mortality increases by about 7.6%. Prompt recognition and treatment can reduce the risk of organ damage, decrease the length of hospital stays, and increase overall survival rates.

Sepsis Awareness and Education: A Public Health Priority

Increasing public awareness about sepsis is crucial in improving outcomes. Many people are unfamiliar with the signs and symptoms of sepsis, which can lead to delayed treatment. Healthcare systems and organizations are working to educate both the public and healthcare providers about sepsis through various initiatives:

• Public awareness campaigns
• Healthcare provider training programs
• Implementation of sepsis screening protocols in hospitals
• Development of rapid response teams specialized in sepsis management

These efforts aim to improve early recognition and treatment of sepsis, ultimately saving lives and reducing the long-term impacts of this serious condition.

What role do healthcare policies play in sepsis management?

Healthcare policies play a crucial role in improving sepsis outcomes. Many hospitals and healthcare systems have implemented sepsis protocols and bundles based on guidelines from organizations like the Surviving Sepsis Campaign. These protocols standardize the approach to sepsis recognition and treatment, ensuring that patients receive timely and appropriate care. Additionally, some regions have implemented mandatory sepsis reporting and quality improvement initiatives to drive better outcomes.

Long-term Effects and Recovery from Sepsis

While the immediate focus in sepsis cases is on survival, it’s important to recognize that sepsis can have long-lasting effects on survivors. Many patients experience what’s known as post-sepsis syndrome, which can include:

• Persistent fatigue and weakness
• Cognitive difficulties, including memory problems
• Mood changes and anxiety
• Recurring infections
• Muscle and joint pain
• Organ dysfunction

Recovery from sepsis can be a long and challenging process, often requiring ongoing medical care, rehabilitation, and support.

How can post-sepsis care be optimized?

Optimizing post-sepsis care involves a multidisciplinary approach. This may include:

• Regular follow-up appointments with healthcare providers
• Physical therapy to regain strength and mobility
• Occupational therapy to assist with daily living activities
• Cognitive rehabilitation for those experiencing memory or concentration issues
• Mental health support to address anxiety, depression, or post-traumatic stress
• Nutritional counseling to support overall recovery

Tailoring care to individual patient needs and providing comprehensive support can significantly improve long-term outcomes for sepsis survivors.

Emerging Research and Future Directions in Sepsis Management

The field of sepsis research is dynamic, with ongoing efforts to improve diagnosis, treatment, and outcomes. Some areas of current focus include:

• Development of more rapid and accurate diagnostic tests
• Exploration of biomarkers for early sepsis detection
• Investigation of novel therapeutic approaches, including immunomodulatory therapies
• Research into personalized treatment strategies based on individual patient characteristics
• Study of long-term outcomes and rehabilitation strategies for sepsis survivors

These research efforts hold promise for enhancing our ability to combat sepsis effectively and improve patient outcomes.

What potential breakthroughs are on the horizon for sepsis treatment?

Several exciting avenues of research show potential for improving sepsis treatment:

• Artificial intelligence-driven early warning systems for sepsis detection in hospital settings
• Gene therapy approaches to modulate the immune response in sepsis
• Development of new classes of antibiotics to combat drug-resistant pathogens
• Exploration of extracorporeal therapies to remove inflammatory mediators from the bloodstream
• Investigation of stem cell therapies to promote tissue repair and organ function recovery

While many of these approaches are still in early stages of research, they represent the cutting edge of sepsis management and offer hope for improved outcomes in the future.

Global Impact and Disparities in Sepsis Care

Sepsis is a global health concern, but its impact and the quality of care available vary significantly across different regions and populations. Understanding these disparities is crucial for developing effective strategies to combat sepsis worldwide.

How does sepsis affect different parts of the world?

The burden of sepsis is not evenly distributed globally:

• Low- and middle-income countries (LMICs) bear a disproportionate burden of sepsis cases and deaths
• Limited access to healthcare, antibiotics, and intensive care facilities in LMICs contributes to higher mortality rates
• In high-income countries, advanced healthcare systems generally provide better outcomes, but disparities still exist among different demographic groups
• Tropical and subtropical regions face unique challenges due to a higher prevalence of infectious diseases that can lead to sepsis

Addressing these global disparities requires a multifaceted approach, including improving healthcare infrastructure, increasing access to essential medicines, and enhancing education and training for healthcare providers in resource-limited settings.

What initiatives are addressing global sepsis disparities?

Several international initiatives are working to address sepsis disparities:

• The World Health Organization’s resolution on sepsis, which aims to improve prevention, diagnosis, and management globally
• The Global Sepsis Alliance, which promotes awareness and improved care worldwide
• International collaborations for sepsis research and guideline development
• Capacity-building programs to enhance sepsis care in resource-limited settings
• Efforts to improve access to essential antibiotics and other critical medications in LMICs

These initiatives represent important steps towards reducing the global burden of sepsis and improving outcomes for all patients, regardless of their geographic location or socioeconomic status.

Does cancer put me at risk for sepsis?

• When am I more likely to get an infection?
• How will I know if I have neutropenia?
• How can I prevent an infection?

Yes. Having cancer and undergoing certain treatments for cancer, such as chemotherapy, can put you at higher risk of developing an infection, and infections can lead to sepsis.

Chemotherapy works by killing the fastest-growing cells in your body—both good and bad. This means that along with killing cancer cells, chemo also kills your infection-fighting white blood cells.

When am I more likely to get an infection?

An infection or sepsis can happen at any time. However, when your body has very low levels of a certain type of white blood cell (neutrophils) that increases your risk of getting an infection. This condition is a common side effect of chemo called neutropenia.

How will I know if I have neutropenia?

Your doctor will routinely test for neutropenia by checking the level of your white blood cells.

How can I prevent an infection?

• Wash your hands often and ask others around you to do the same.
• Avoid crowded places and people who are sick.
• Talk to your doctor about getting a flu shot or other vaccinations.
• Take a bath or shower every day (unless told otherwise).
• Use an unscented lotion to try to keep your skin from getting dry or cracked.
• Clean your teeth and gums with a soft toothbrush.
• Use a mouthwash to prevent mouth sores (if your doctor recommends one).
• Do not share food, drink cups, utensils or other personal items, such as toothbrushes.
• Cook meat and eggs all the way through to kill any germs.
• Carefully wash raw fruits and vegetables.
• Protect your skin from direct contact with pet bodily waste (urine or feces).
• Wash your hands immediately after touching an animal or removing its waste, even after wearing gloves.
• Use gloves for gardening.

For a person with cancer, almost any infection can lead to sepsis, for more information see Preventing Infections in Cancer Patients.

Procalcitonin

Procalcitonin (PCT) – a marker of sepsis!

Procalcitonin (PCT) is a polypeptide that is an inactive precursor of calcitonin. Normally, PCT is formed from preprocalcitonin in C-cells of the thyroid gland under the influence of calcium-dependent factors. In healthy individuals, all the resulting PCT is converted into calcitonin and practically does not enter the bloodstream. Normally, in the early period of the newborn, an increase in the level of PCT is noted.
In severe bacterial infections and sepsis, the massive formation of endotoxins, an increase in the levels of pro-inflammatory cytokines IL-6 and TNF-α leads to an increase in PCT synthesis not only in the thyroid gland, but also extrathyroidally: first of all, in leukocytes, monocytes, as well as in neuroendocrine cells of the lungs, intestines and liver. All this leads to a rapid and sharp increase in the level of PCT (already 6-12 hours after the generalization of the process) against the background of maintaining the level of calcitonin.

It must be taken into account that the level of PCT increases only with the generalization of a bacterial infection (sepsis) and reflects its degree, local foci do not lead to an increase in the level of the marker. Therefore, not only the presence of an increase is of diagnostic importance, but also the degree of increase and the dynamics of the PCT level. In addition, it should be taken into account that an increase in PCT does not occur with fungal and viral infections, allergic and autoimmune diseases, which allows differential diagnosis of these conditions.

The half-life of PCT is 25-30 hours, which allows it to be used as a marker of the effectiveness of antibiotic therapy, since after successful surgical treatment or antibiotic therapy, the level of procalcitonin in the blood decreases rapidly – by 30-50% per day.

On the other hand, if the level of procalcitonin persists for more than 4 days, correction of the therapy is necessary. If after treatment there is no rapid decrease in the level of PCT, then the prognosis of the disease is doubtful. Constantly increasing PCT values ​​indicate a poor prognosis of the disease. In acute pancreatitis, PCT is an indicator of the severity of the course and a marker of infectious complications.

An increase in the level of procalcitonin in the blood above 1.8 ng / ml indicates the development of infectious complications (sensitivity – 80-95%, specificity – 88-93%).

The level of PCT clearly correlates with the severity of the inflammatory process:

• PCT < 0.5 ng/ml - low risk of severe sepsis and/or septic shock.

• PCT from 0.5 to 2 ng / ml – moderate systemic inflammatory response syndrome (SIRS) – “gray zone”. It is impossible to make a diagnosis of sepsis with certainty, it is recommended to repeat the measurement within 6-24 hours.

• PCT> 2 ng / ml – severe systemic inflammatory response syndrome (SIRS), high risk of severe sepsis and / or septic shock (sensitivity 85%, specificity 93%).

• PCT 10 ng/mL and above – severe systemic inflammatory response syndrome (SIRS) – almost always due to severe bacterial sepsis or septic shock. Such levels of PCT are often associated with MODS (Multiple Organ Failure Syndrome), and indicate a high risk of death.

Septic shock. What is septic shock?

IMPORTANT
The information in this section should not be used for self-diagnosis or self-treatment. In case of pain or other exacerbation of the disease, only the attending physician should prescribe diagnostic tests. For diagnosis and proper treatment, you should contact your doctor.

Septic shock is a serious pathological condition that occurs when a massive intake of bacterial endotoxins into the blood. Accompanied by tissue hypoperfusion, a critical decrease in blood pressure and symptoms of multiple organ failure. The diagnosis is made on the basis of the general clinical picture, which combines signs of damage to the lungs, cardiovascular system (CVS), liver and kidneys, and centralization of blood circulation. Treatment: massive antibiotic therapy, infusion of colloid and crystalloid solutions, maintenance of CCC activity by introducing vasopressors, correction of respiratory disorders by mechanical ventilation.

General

Septic shock (SS) is also called infectious-toxic shock (ITS). As an independent nosological unit, pathology was first described in the 19th century, however, a full-fledged study with the development of specific anti-shock measures began no more than 25 years ago. It can occur with any infectious process. Most often occurs in patients of surgical departments, with meningococcal septicemia, typhoid fever, salmonellosis and plague. It is common in countries where the largest number of bacterial and parasitic diseases is diagnosed (Africa, Afghanistan, Indonesia). More than 500,000 people around the world die each year from TSS.

Septic shock

Reasons

In the vast majority of cases, pathology develops against the background of weakened immune responses. It occurs in patients suffering from chronic severe diseases, as well as in the elderly. Due to physiological characteristics, sepsis is more often diagnosed in men. The list of the most common diseases in which TTS events can occur includes:

• Foci of purulent infection. Signs of a systemic inflammatory reaction and associated disorders in the functioning of internal organs are noted in the presence of volumetric abscesses or phlegmon of soft tissues. The risk of a generalized toxic response increases with a long course of the disease, the absence of adequate antibiotic therapy, and the patient’s age over 60 years.
• Prolonged stay in the ICU. Hospitalization in the intensive care unit is always associated with the risk of sepsis and infectious shock. This is due to constant contact with microflora resistant to antibacterial drugs, weakening of the body’s defenses as a result of a serious illness, the presence of multiple gates of infection: catheters, gastric tubes, drainage tubes.
• Wounds. Violations of the integrity of the skin, including those that occurred during surgery, significantly increase the risk of infection with a highly contagious flora. TSS begins in patients with contaminated wounds who have not received timely care. Tissue trauma during surgery becomes the cause of a generalized infection only if the rules of asepsis and antisepsis are not followed. In most cases, septic shock occurs in patients who have undergone manipulations on the stomach and pancreas. Another common cause is diffuse peritonitis.
• Taking immunosuppressants. Immune depressant drugs (mercaptopurine, krizanol) are used to suppress the rejection reaction after organ transplantation. To a lesser extent, the level of self-protection decreases with the use of chemotherapeutic agents – cytostatics intended for the treatment of oncological diseases (doxorubicin, fluorouracil).
• AIDS. HIV infection in the AIDS stage leads to the development of atypical sepsis, provoked not by a bacterial culture, but by a fungus of the genus Candida. Clinical manifestations of the disease are characterized by a low degree of severity. The lack of an adequate immune response allows the pathogenic flora to multiply freely.

The causative agent of sepsis is gram-positive (streptococci, staphylococci, enterococci) and gram-negative (Enterobacter cloacae, Clostridium pneumoniae) bacteria. In many cases, cultures are insensitive to antibiotics, making it difficult to treat patients. Septic shock of viral origin is currently controversial among specialists. Some representatives of the scientific world argue that viruses are unable to cause pathology, others that an extracellular life form can provoke a systemic inflammatory response, which is the pathogenetic basis of TSS.

Pathogenesis

The symptoms are based on the uncontrolled spread of inflammatory mediators from the pathological focus. In this case, activation of macrophages, lymphocytes and neutrophils occurs. A systemic inflammatory response syndrome occurs. Against this background, peripheral vascular tone decreases, the volume of circulating blood decreases due to increased vascular permeability and fluid stagnation in the microvasculature. Further changes are due to a sharp decrease in perfusion. Insufficient blood supply causes hypoxia, ischemia of internal organs and disruption of their function. The most sensitive is the brain. In addition, the functional activity of the lungs, kidneys and liver worsens.

In addition to SVR, endogenous intoxication plays an important role in the formation of septic shock. In connection with a decrease in the efficiency of excretory systems, products of normal metabolism accumulate in the blood: creatinine, urea, lactate, guanine and pyruvate. In internal environments, the concentration of intermediate results of lipid oxidation (skatol, aldehydes, ketones) and bacterial endotoxins increases. All this causes severe changes in homeostasis, acid-base balance disorders, disturbances in the functioning of receptor systems.

Classification

The state of shock is classified according to pathogenetic and clinical principles. Pathogenetically, the disease can be “warm” and “cold”. Warm shock is characterized by an increase in cardiac output against the background of a decrease in overall vascular tone, endogenous hypercatecholaminemia, and dilation of intradermal vessels. The phenomena of organ failure are expressed moderately. The cold variety is manifested by a decrease in cardiac output, a sharp decrease in tissue perfusion, centralization of blood circulation, and severe MOF. According to the clinical course, septic shock is divided into the following varieties:

• Compensated. Consciousness is clear, safe, the patient is inhibited, but fully contactable. Arterial pressure is slightly reduced, the level of SBP is not less than 90 mm Hg. Tachycardia is detected (PS <100 bpm). Subjectively, the patient feels weakness, dizziness, headache and decreased muscle tone.
• Subcompensated. The skin is pale, the heart sounds are deaf, the heart rate reaches 140 beats per minute. SBP <90 mm. rt. Art., Respiration is rapid, shortness of breath up to 25 movements / min. Consciousness is confused, the patient answers questions with a delay, poorly understands what is happening around, where he is. Speech is quiet, slow, unintelligible.
• Decompensated. Marked depression of consciousness. The patient answers in monosyllables, in a whisper, often after 2-3 attempts. Motor activity is practically absent, the reaction to pain is weak. The skin is cyanotic, covered with sticky cold sweat. The heart sounds are deaf, the pulse on the peripheral arteries is not determined or is sharply weakened. Heart rate up to 180 beats / min, respiratory rate 25-30, shallow breathing. BP below 70/40, anuria.
• Terminal (irreversible). Consciousness is absent, the skin is marbled or gray, covered with bluish spots. Pathological breathing according to the type of Biot or Kussmaul, the respiratory rate decreases to 8-10 times / minute, sometimes breathing stops completely. SBP less than 50 mm Hg. pillar. There is no urination. The pulse is hardly palpable even on the central vessels.

Symptoms of septic shock

One of the defining signs of TSS is arterial hypotension. It is not possible to restore the level of blood pressure even with an adequate infusion volume (20-40 ml / kg). To maintain hemodynamics, it is necessary to use pressor amines (dopamine). Acute oliguria is noted, diuresis does not exceed 0.5 ml/kg/hour. Body temperature reaches febrile values ​​- 38-39 ° C, it is poorly reduced with the help of antipyretics. To prevent convulsions caused by hyperthermia, it is necessary to use physical methods of cooling.

90% of cases of SS are accompanied by respiratory failure of varying severity. Patients with decompensated and terminal course of the disease need hardware respiratory support. The liver and spleen are enlarged, compacted, their function is impaired. There may be intestinal atony, flatulence, stools mixed with mucus, blood and pus. In the later stages, symptoms of disseminated intravascular coagulation occur: petechial rash, internal and external bleeding.

Complications

Septic shock leads to a number of severe complications. The most common of these is multiple organ failure, in which the function of two or more systems is impaired. First of all, the central nervous system, lungs, kidneys and heart suffer. Somewhat less common damage to the liver, intestines and spleen. Mortality among patients with MOF reaches 60%. Some of them die 3-5 days after being removed from a critical state. This is due to organic changes in internal structures.

Another common consequence of TSS is bleeding. With the formation of intracerebral hematomas, the patient develops a clinic of acute hemorrhagic stroke. The accumulation of extravasate in other organs can lead to their compression. A decrease in blood volume in the vascular bed potentiates a more significant decrease in blood pressure. DIC against the background of infectious-toxic shock causes the death of the patient in 40-45% of cases. Secondary organ damage, provoked by microthromboses that occur at the initial stage of coagulopathy formation, is observed in almost 100% of patients.

Diagnostics

The diagnosis is established by an anesthesiologist-resuscitator. The assumption is based on clinical data, however, it is possible to accurately determine the existing condition only if there are results of hardware and laboratory studies. If septic shock is suspected, all tests are done in an emergency mode, “according to cito”. Resuscitation activities should begin without waiting for the end of the support services. A comprehensive examination necessary to determine and confirm TTS includes:

• Examination and physical examination. Implemented directly by the attending physician. The specialist detects the characteristic clinical signs of a shock state. For this, tonometry, a visual assessment of the color of the skin, features of respiratory movements, counting the pulse and respiratory rate, auscultation of the heart and lungs are performed. If complications are suspected, an assessment of the neurological status is necessary for symptoms of cerebral hemorrhage.
• Hardware research. Has an auxiliary value. The patient is shown to control the condition using an anesthetic monitor. The screen of the device displays information about the value of blood pressure, heart rate, degree of blood oxygen saturation (with lung failure SpO2<90%) and coronary rhythm. Against the background of respiratory disorders and toxic damage to the myocardium, tachycardia, arrhythmia and blockade of intracardiac conduction may occur.
• Laboratory research. Allows you to identify existing violations of homeostasis, failures in the work of internal organs. In patients with shock of septic origin, elevated levels of creatinine (> 0.177 mmol / l), bilirubin (> 34.2 μmol / l), lactate (> 2 mmol / l) are found. Thrombocytopenia (<100 × 10⁹/l) indicates a violation of coagulation. With progressive anemia, erythrocytes are 1.5-2.5 million per 1 mm3, hemoglobin is below 90 g/l. venous blood pH <7.3 (metabolic acidosis).

Treatment of septic shock

Patients are given intensive care. Treatment is carried out in intensive care units using the methods of hardware and drug support. The attending physician is a resuscitator. Consultation with an infectious disease specialist, cardiologist, gastroenterologist and other specialists may be required. It is required to transfer the patient to artificial lung ventilation, round-the-clock supervision of nurses, parenteral feeding. Mixtures and products intended for introduction into the stomach are not used. All methods of exposure are conditionally divided into pathogenetic and symptomatic:

• Pathogenetic treatment. If sepsis is suspected, the patient is prescribed antibiotics. The scheme should include 2-3 drugs of various groups with a wide spectrum of action. The selection of the drug at the initial stage is carried out empirically, in accordance with the expected sensitivity of the pathogen. At the same time, blood is taken for sterility and susceptibility to antibiotics. The result of the analysis is prepared within 10 days. If by this time it was not possible to select an effective drug regimen, the study data should be used.
• Symptomatic treatment. It is selected taking into account the existing clinical picture. Usually patients receive massive infusion therapy, glucocorticosteroids, inotropic agents, antiplatelet agents or hemostatics (depending on the state of the blood coagulation system). In severe cases of the disease, blood products are used: fresh frozen plasma, albumin, immunoglobulins. If the patient is conscious, the introduction of analgesic and sedative drugs is indicated.

Prognosis and prevention

Septic shock has a poor prognosis for life. With a subcompensated course, about 40% of patients die. Decompensated and terminal varieties end in the death of 60% of patients. In the absence of timely medical care, mortality reaches 95-100%. Some patients die a few days after the elimination of the pathological condition. Prevention of TSS consists in the timely relief of foci of infection, the competent selection of antibiotic therapy in surgical patients, compliance with antiseptic requirements in departments involved in invasive manipulations, and the maintenance of an adequate immune status in representatives of the HIV-infected stratum of the population.
