A Canadian study to determine the prevalence of intra-abdominal hypertension (IAH) finds a higher than expected rate.
30% at admission, another 15% during admission.
Abdominal Compartment Syndrome 3%
28% in non-ventilated patients.
Higher mortality vs. those without IAH (30% vs. 11%)
Predictors of IAH included obesity, mechanical ventilation and >3L 24 hour fluid balance.
They advocate for possible routine intra-abdominal pressure measurement in ICU, which is simple and inexpensive.
