[Intestinal malperfusion in critical care patients]

Knichwitz G, Kruse C, van Aken H

Abstract

Due to the bowel's poor tolerance of hypoxia, intestinal malperfusion presents as a grave disease with high mortality. The intensivist is confronted with this condition in association with other underlying diseases, in the course of surgery, during application of medication or associated with invasive therapy. In a critical care setting, the non-occlusive mesenteric ischemia (NOMI) is of increasing importance. Since critical care patients often lack clinical symptoms, special attention is required and one main factor of the patient's prognosis is early diagnosis. This review summarizes pathophysiology and diagnostic aspects and the range of therapeutic and preventive measures.
