Background. We aimed to describe the incidence of intra-abdominal hypertension IAH and gastrointestinal GI symptoms and related outcome in mechanically ventilated MV patients. Methods. Intra-abdominal pressure IAP and gastric residual volumes were measured at least twice daily. IAH was defined as a mean daily value of  mmHg. Results. 398 patients were monitored for all together 2987 days. GI symptoms occurred in patients. 152 patients developed IAH. Majority of patients with IAH had GI symptoms. The more severe IAH was associated with the higher number of concomitant GI symptoms . 142 patients developed both IAH and at least one GI symptom at any time in ICU, and in 77 patients they occurred simultaneously on the same day. This subgroup had the highest ICU mortality . In contrast, the small group of patients presenting only IAH, but not GI symptoms 10 patients, had no lethal outcome. Three patients died without showing either IAH or GI symptoms. Conclusions. GI symptoms and IAH often, but not always, occur together. The patients having IAH solely without developing GI symptoms have rather good outcome.
