title: [Postoperative infections in critically ill patients].
abstract: Patients subjected to surgery often develop nosocomial infections, among which the intra-abdominal ones stand out as being a common cause of septicemia, multi-organ failure, and death of the critical patients. Advances have been made in the study of the physiopathology by studying the mediators which are responsible for the systemic inflammatory response, the microbiology (changes in the pathogen type and in the antimicrobial sensitivity), and for the clinical picture (cholecystitis, tertiary peritonitis). Abdominal ultra-sound and computerized axial tomography have contributed greatly to the diagnosis of these infections. The new treatment techniques are discussed, both of the drainage of the septic focus (percutaneous or surgical), as of the antimicrobial treatment and the supportive measures. The diagnostic and therapeutic advances have modified the prognosis of these patients, although this continues to be poor when there is development of the multi-organ failure syndrome.
