Intra-abdominal infections

Abstract

Intra-abdominal infections in the hospitalized patient differ from those arising in the community in their clinical presentation, sites of involvement, and characteristic microbiology. They are also associated with greater morbidity and mortality. New onset organ dysfunction, more than acute abdominal pain and tenderness, is the predominant clinical manifestation. Successful management depends on aggressive resuscitation and hemodynamic support, administration of adequate antimicrobial therapy, and the timely use of source control measures appropriate to the clinical situation.
