Sepsis definition: What’s new in the Treatment Guidelines

Sepsis is a life-threatening organ dysfunction caused by an unregulated response of a host.Septic shock is its most severe form.It is manifested by a drop in blood pressure, which decreases tissue perfusion pressure, causing hypoxia that is characteristic of shock.Sepsis is still one of the leading causes of mortality worldwide.Its incidence has increased since the first consensus definitions were established in 1991.Raising sepsis awareness, its significance and the need for better treatment, has led to an improvement in in defining sepsis and the development of guidelines for its treatment.The first guidelines were published in 2004, the second 2008, the third 2013, the fourth 2016, and the last revised guidelines appeared in 2021.This paper will describe the previous and new definitions of sepsis and septic shock, the previous guidelines for the recognition and treatment, and the latest recommendations for treatment.Timely diagnosis is crucial for the outcomes for patients with sepsis and septic shock.The fact is that the sepsis care bundles have been modified to increasingly shorter time determinants, which emphasizes the importance of emergency physicians, who frequently first recognize and begin emergency treatment of septic patients.
