Abdominal hypertension and compartmental syndrome in intensive care medicine

Introduction and objectives

The objective of this trial was to compare abdominal hypertension and abdominal compartmental syndrome (ACS) in patients under risk for these pathologies in the ICU.


Eighty-nine patients with monitoring indications for intra-abdominal pressure (IAP) based on clinical or surgical admission diagnosis in the ICU were included. Measurements via an indirect method through the vesical catheter were made at three distinct timepoints: at admission, and at 6 hours and 12 hours.


The incidence of ACS was 14.6% (13 patients); in the total sample, the male sex prevailed at 63% (56 patients). The patients had been distributed into two groups: with ACS and without ACS. Gastric surgery diagnosis predominated in both groups (84.6%/57.9%; P < 0.067). Global mortality was 30.3% (27 patients): 53.8% (seven patients) in the group with ACS and 26.3% (20 patients) in the group without ACS; P < 0.046. Table 1 describes the sample.

Table 1


Abdominal hypertension and ACS are frequent diagnostics in intensive care medicine; superior average values of the IAP at admission, at 6 hours and at 12 hours to 28 mmHg are correlated with the biggest incidence of ACS and greater mortality.
