This observational study on intraabdominal pressure (IAP) in adult patients admitted for at least 48 hours to a mixed medical and surgical intensive care department (ICU) of a university hospital was started to determine the value of routine monitoring of IAP.
The IAP was measured non-invasively (bladdercatheter) twice daily until discharge from the ICU or removal of the bladder catheter. We present the results of 180 patients included during a 6-month period. A total of 2201 measurements were performed. For each patient, the first IAP (IAP1), maximal IAP (IAPmax) and mean IAP (IAPm) for the observation period was determined. Patients were stratified into 2 groups depending on 30-day survival.
67 patients (1101 measurements) did not survive. IAP1 was 8.7±5.1mmHg, IAPmax was 15.6±4.8 and IAPm was 9.3±2.9. We recorded 222 (in 49 patients) IAP-values over 12mmHg (20%) of which 18 IAP-values over 19mmHg (1.6%) in 12 patients.
113 patients (1100 measurements) had a favourable outcome. IAP1 was 6.9±5.0 mmHg, IAPmax was 11.9±5.2 and IAPm was 7.0±3.3. We recorded 165 (in 53 patients) IAP-values over 12mmHg (15%) of which 14 IAP-values over 19mmHg (1.3%) in 9 patients.
The two-tailed student's t-test between the 2 groups was significant for all IAP-values (9.17±4.4 versus 7.6±4.7, pThe present data let us conclude that IAP is generally higher in non-survivors than in survivors but that these differences are not statistically significant and that survivors can have elevated values of IAP. In a general ICU population elevated values are usually isolated and values compatible with abdominal compartment syndrome are rare and usually outliers. Routine monitoring of IAP in all patients admitted to the ICU does not seem warranted.
