The Impact of Intra-Abdominal Pressure on Mortality and Morbidity in Patients Undergoing Open-Heart Surgery
Completed
Conditions studied: Intra-Abdominal Hypertension, Postoperative Complications
In brief
This prospective observational study evaluated whether increased intra-abdominal pressure, meaning increased pressure inside the abdomen, is associated with postoperative complications and mortality in adults undergoing elective open-heart surgery with cardiopulmonary bypass. Intra-abdominal pressure was measured through the urinary bladder at three time points: after anesthesia induction, after closure of the sternum, and two hours after admission to the intensive care unit. Participants with an intra-abdominal pressure of 12 mmHg or higher at any measurement were compared with those whose pressure remained below 12 mmHg. The study examined postoperative recovery outcomes, including time to extubation, length of stay in the intensive care unit and hospital, postoperative complications, and mortality. It also aimed to identify perioperative factors associated with increased intra-abdominal pressure. No study-specific treatment or intervention was assigned, and all patients received standard perioperative care.
