[Intensive care management of diffuse septic peritonitis]

Abstract

The function of the peritoneum in severe abdominal sepsis involves specific properties and defence mechanisms: large surface, efficient barrier, continuous mobility, capacity of migration, multiplication, secretion and absorption. The development of peritonitis supposes an initial lesion of the peritoneal surface by septic or biochemical mechanism. Peritoneal response consists of: septation of the abdominal wall, adhesion of the omentum to damaged surfaces or visceral perforation, massive stepping up of cellular and humoral defence mechanism. In our opinion therapeutic procedures consist of: early surgical approach and management of the patient in an intensive care unit. The aim of the medical therapy is: treatment of multiple organ failure (anti-infectious therapy, hemodynamic support, treatment of respiratory and renal failure, support of the hepatic failure and balancing of metabolic changes) and prevention of the most common complications: bleeding from upper gastrointestinal tract and thromboembolic risks.
