ABSTRACT
Introduction: Intra-abdominal hypertension (IAH), asustained and repeated steady state rise in intra-abdominalpressure (IAP) above 12 mmHg, was reported as a hiddencause contributing to morbidity and mortality in criticallyill patients. This study was aimed to find out the possiblerelationship between IAH and acute kidney injury (AKI) inICU patients.Material and methods: Prospective cohort study wasconducted among patients admitted in medical and surgicalICU. Consecutive patients coming under the inclusioncriteria were selected and IAH was measured using pressuretransducer technique. IAP was measured at the time ofadmission, at 24 hours, 48hours and also at the end of 72hours.Other parameters were collected based on a standard proformaprepared.Results: Eighty patients were included in our study, of which24 patients had IAH. Mean age in patients with IAH wasobtained as 63.08 ± 12.37 years with a male predominance.Maximum patients were belonging to age group of 61-70yrs (25%), 9 patients were below 40 yrs and 14 patientswere above 81yrs. Mean IAP was calculated to be 11.65 ±3.15. Only 9 patients were in grade IV (11.3%). Risk factorsassociated were found to be ascites, upper GI bleed andmetabolic encephalopathy. IAH and AKI were found to besignificantly correlated (odds ratio=2.666 with CI 0.98-7.25).Conclusion: Rising intra-abdominal pressure is found to havehigher incidence of renal failure than those with establishedIAH. IAH has been found to be a clinically significant riskfactor for development of AKI in ICU patients.
