Study Notes

Definition and Characteristics of Septic Shock

Septic shock is a life-threatening condition characterized by severe abnormalities in circulatory and cellular metabolism, leading to cellular and tissue injury.
It is a subset of sepsis in which underlying circulatory, cellular, and metabolic abnormalities are severe enough to increase mortality rates substantially.

Epidemiology of Septic Shock

Prevalence of septic shock in intensive care units ranges from 18% to 50% depending on the case mix of the study.
Shock occurs in 8% of sepsis cases, but its progression to severe septic shock is reported in 3% to 6% of cases.
Septic shock is the most common form of shock in intensive care units.
It is the leading cause of death in intensive care units, accounting for about 30% of all deaths each year.
There is a year-over-year increase of 5% to 7% in septic shock cases, particularly with an increase in emergency department visits and hospital admissions.
A 15% increase in septic shock cases occurred in 2020 compared to 2017.

Pathophysiology of Septic Shock

Sepsis is a life-threatening organ dysfunction due to a dysregulated host response to an infection.
Septic shock is a subset of sepsis in which underlying circulatory, cellular, and metabolic abnormalities are sufficiently profound to substantially increase mortality.
The Sepsis-3 definition comprehensively describes septic conditions leading up to and including septic shock.

Importance of Understanding Septic Shock

Prompt recognition, effective intervention, and management, and appropriate escalation of care to higher-level facilities offer the best chance of survival for patients with septic shock.
Understanding the definition, epidemiology, pathophysiology, early recognition, and diagnosis of septic shock is crucial for effective management.

Hemodynamics and Septic Shock Management

Hemodynamics, oxygen supply and demand, oxygen extraction, liver function, and renal function are essential aspects of septic shock management.
Knowledge of hemodynamics and its influence on other functions can be used toward the effective management of septic shock.

Septic shock is a life-threatening condition characterized by severe abnormalities in circulatory and cellular metabolism. It is a subset of sepsis that increases mortality rates substantially. Prevalence varies in intensive care units.
