Abdominal compartment syndrome in the intensive care unit.

Abstract

The abdominal compartment syndrome is an increasingly recognized complication of both medical and surgical patients in the ICU setting. This syndrome has been described in a wide variety of clinical scenarios and results from a persistent elevation in intra-abdominal pressure characterized by graded organ system dysfunction. Manifestations of abdominal compartment syndrome include cardiovascular, pulmonary, renal, splanchnic, and neurologic impairment. The diagnosis of abdominal compartment syndrome requires a high level of clinical suspicion combined with an increased intra-abdominal pressure, usually obtained via urinary bladder pressure measurement. Patients at risk for abdominal compartment syndrome warrant close monitoring and we recommend prompt abdominal decompression following documentation of increased intra-abdominal pressure in the setting of physiologic compromise. Abdominal compartment syndrome can significantly contribute to the morbidity and mortality of both medical and surgical patients alike in the ICU. The signs and symptoms of abdominal compartment syndrome should become familiar to all critical care practitioners.
