ABSTRACTIntraabdominal hypertension (IAH) and the abdominal compartment syndrome (ACS) are important causes of morbidity and mortality in critically ill patients. Intraabdominal pressure (IAP) monitoring has become a fundamental procedure in the intensive care unit because of its role in the patient’s whole treatment.
Normally, intraabdominal pressure is about 5 mmHg though it can rise in the obese, with exercise and with the Valsalva maneuver.
Intraabdominal hypertension is a condition where sustained elevated IAP provokes a functional disorder to the abdominal contents and adjacent extraperitoneal organs.
There are several ways to measure IAP via the urinary bladder, this being the most reproducible and exact method. For this purpose either an open or closed urinary recollection system can be used. It can also be measured either intermittently or continuously.
General medical support is very important, but the precise moment of abdominal decompression must be considered according to clinical evolution and IAP monitoring. In selected cases, surgical decompression is the only treatment for improving hemodynamics, pulmonary function and intestinal perfusion.
