Lisun Y. Prophylaxis and correction of complications, of intraabdominal hypertension in perioperative period

In dissertation based on the prospective analysis of 442 patients during anesthesia we evaluated the high accuracy of indirect intraabdominal pressure (IAP) test that make it possible to perform an effective monitoring in patients with diseases of abdominal and retroperitoneal organs. It was shown that median IAP is 3 mm Hg, it had a direct correlation with age of the patient (r=0,7) and median AP (r=0,69). Normal IAP was 0,7 4,9 mm Hg. Increase of IAP on 5 mm Hg resulted in significant changes of HR and EDV, on 10 mm Hg - HR, EDV, EF In different diseases of the abdominal organs we combined patients with basic intraabdominal hypertension, normal IAP and basic intraabdominal hypotension, dynamics of IAP і abdominal perfusion pressure during treatment was studied. Maximal basic IAP, its maximal increase after operation and its maximal duration were found in patients with gigantic postoperative abdominal wall hernia. Under the influence of compressive preoperative treatment the rate and duration of IAP significantly decreased. The increase of abdominal perfusion pressure were not significant. Implementation of the continuous epidural analgesia resulted in increase of rate and duration IAP without significant influence on rate of abdominal perfusion pressure.
