The abdominal compartment syndrome.

The abdominal compartment syndrome refers to the alterations in respiratory mechanics, hemodynamic parameters and renal function that occur as a result of a sustained increase in intra-abdominal pressure. The syndrome may follow a diverse series of insults, including laparotomy for severe abdominal trauma, ruptured abdominal aortic aneurysm and intra-abdominal infection. Diagnosis depends on recognizing the clinical picture in patients at risk, followed by an objective measurement of intra-abdominal pressure. Successful management may require abdominal decompression with temporary abdominal closure. Despite urgent decompression, the death rate is high because of the severity of the patients' underlying illness.
