What is Sepsis Infection? 10 Sepsis Shock Symptoms!

Septic shock is a severe and potentially life-threatening medical condition that occurs as a complication of an infection. It is characterized by a systemic response of the body to an overwhelming infection, leading to a cascade of events that can cause multiple organ failure and a significant decrease in blood pressure. Septic shock is considered a medical emergency and requires prompt and intensive medical intervention.

Here’s an overview of the key aspects of septic shock:

Causes: Septic shock is most commonly caused by bacterial infections, but it can also result from viral or fungal infections. These infections can originate from various sources, including the lungs (pneumonia), urinary tract (urinary tract infections), abdomen (peritonitis), and bloodstream (bacteremia).

Symptoms: Symptoms of septic shock can vary but often include:

  • High fever or very low body temperature
  • Rapid heart rate
  • Rapid and shallow breathing
  • Low blood pressure
  • Confusion or altered mental state
  • Profound fatigue or weakness
  • Cold, clammy skin
  • Decreased urine output

Pathophysiology: In septic shock, the body’s immune response to the infection becomes dysregulated. This leads to the release of a large amount of inflammatory mediators (such as cytokines) into the bloodstream. These mediators cause widespread inflammation, dilate blood vessels, and lead to fluid leakage into tissues. The combination of inflammation and fluid loss results in reduced blood volume, decreased blood pressure, and inadequate blood flow to vital organs.

Treatment: Septic shock is a medical emergency requiring immediate intervention. Treatment involves addressing the underlying infection while also providing supportive care to stabilize the patient’s condition. Treatment measures include:

  1. Intravenous Antibiotics: Administering appropriate antibiotics to target the causative infection.
  2. Fluid Resuscitation: Administering fluids intravenously to restore blood volume and improve blood pressure.
  3. Vasopressor Medications: Medications that constrict blood vessels and raise blood pressure may be necessary to maintain adequate perfusion to vital organs.
  4. Oxygen Therapy: Providing supplemental oxygen to ensure proper oxygenation of tissues.
  5. Intensive Care: Patients with septic shock are typically treated in an intensive care unit (ICU) where their vital signs and organ function can be closely monitored.
  6. Source Control: Identifying and addressing the source of infection, which might involve drainage of abscesses or removal of infected tissue.
  7. Supportive Measures: Addressing complications such as kidney failure, respiratory distress, and clotting abnormalities.

Early recognition and treatment are crucial for improving the chances of survival in septic shock. If you suspect someone is experiencing septic shock or if you’re exhibiting symptoms yourself, seek immediate medical attention. Timely medical intervention can greatly improve outcomes in this serious condition.

What Happens During a Septic Shock?

Septic shock is a very complex condition that involves the immune system and its relationship with the source of infection. We can see the same immune response in a septic shock, but instead of being located in the affected tissue, it is found throughout the body. For example, a severe kidney infection would trigger the release of inflammatory cytokines, which cause vasodilatation, an accelerated influx of monocytes and neutrophils, changes in coagulation, and an increase in endothelial permeability.

In septic shock, all of these body reactions are found inside and outside the kidneys. This immune reaction causes thrombosis in organ capillaries, endothelial damage, edema, and inflammation on a systemic scale. It is an exaggerated inflammatory response that is not only found in the organ currently triggering the infection.

The exact pathophysiology of this condition is not entirely understood. However, we know that the most dangerous abnormalities in septic shock have to do with alterations in the circulatory system. Coagulation abnormalities, hypotension, hypoperfusion, and endothelial damage slowly cause organ dysfunction, not limited to the infected organ. That is why it is also known as multi-organ failure.
