Organ support in sepsis: A panoramic view from infection to death

Abstract

Despite significant advancements in medical research, sepsis persists as a leading cause of mortality in intensive care units (ICUs). Sepsis intricately contributes to organ failure, amplifying both morbidity and mortality. In these instances, a comprehensive comprehension of the physiology of each organ is imperative for accurate diagnosis and effective management. Within the context of an ICU clinical scenario, a meticulous evaluation and monitoring of six pivotal organ systems cardiovascular, renal, respiratory, neurological, hematological, and hepatic are essential. The primary objective in managing sepsis-induced organ failure is the early detection and intervention, encompassing timely administration of antibiotics, identification and control of the infection source, and implementation of supportive therapy. Despite the extensive body of medical literature, there is a conspicuous absence of evidence-based multi-organ management strategies for such patients. The intricate interplay between organs, commonly referred to as organ crosstalk, presents a formidable challenge in navigating the complexities of sepsis management.
