Jun 12, 2023 · Understanding the pathophysiology and continuum of septic shock is imperative in initiating appropriate treatment measures. [1] Functionally, septic shock is defined by persistent hypotension despite adequate fluid resuscitation from 60 ml/kg to 80 mL/kg of either crystalloid or colloid fluid.

Apr 28, 2023 · Sepsis is defined as a life-threatening organ dysfunction caused by a dysregulated host response to infection. Septic shock should be considered a subset of sepsis in which underlying circulatory, cellular, and metabolic abnormalities contribute to a greater risk of mortality than that posed by sepsis alone [ 1 ].

Symptoms of septic shock
Sepsis may progress to septic shock. Septic shock is a severe drop in blood pressure. Progression to septic shock raises the risk of death. Symptoms of septic shock include:
Any infection could lead to sepsis. Go to a health care provider if you have symptoms of sepsis or an infection or wound that isn't getting better.
Symptoms such as confusion or fast breathing need emergency care.

Any type of infection can lead to sepsis. This includes bacterial, viral or fungal infections. Those that more commonly cause sepsis include infections of:
•Lungs, such as pneumonia.
•Kidney, bladder and other parts of the urinary system.
•Digestive system.
•Bloodstream.
•Catheter sites.
Some factors that increase the risk infection will lead to sepsis include:
•People over age 65.
•Infancy.
•People with lower immune response, such as those being treated for cancer or people with human immunodeficiency virus (HIV).
•People with chronic diseases, such as diabetes, kidney disease or chronic obstructive pulmonary disease (COPD).
•Admission to intensive care unit or longer hospital stays.
As sepsis worsens, vital organs, such as the brain, heart and kidneys, don't get as much blood as they should. Sepsis may cause atypical blood clotting. The resulting small clots or burst blood vessels may damage or destroy tissues.
Most people recover from mild sepsis, but the mortality rate for septic shock is about 30% to 40%. Also, an episode of severe sepsis raises the risk for future infections.

The SCCM Pediatric Sepsis Definition Task Force developed new criteria for defining sepsis and septic shock in children based on evidence from an international survey, a systematic review and meta-analysis, and a new organ dysfunction score developed based on more than 3 million electronic health record encounters from 10 sites on 4 continents.
Feb 2, 2016 · Septic shock should be defined as a subset of sepsis in which particularly profound circulatory, cellular, and metabolic abnormalities are associated with a greater risk of mortality than with sepsis alone.
Sepsis occurs when your immune system has an extreme reaction to an infection. The inflammation throughout your body can cause dangerously low blood pressure. You need immediate treatment if you have septic shock. Treatment may include antibiotics, oxygen and medication.
