Changes of Intra Abdominal Pressure During Surgeries in Prone Position as a Marker of Renal Damage

Background: Patients undergoing surgical operations in prone position do not have a measure of intra abdominal pressure as a standard procedure. Many of them could have elevated values of this parameter and could be exposed to possible renal damage due to a stiffening of the abdominal muscles while being positioned prone.Purpose of study: Intraoperative intrabdominal pressure measurement and evaluation of correlation with possible postsurgical complications.Methodology: Electronic device able to measure intra abdominal pressure is connected between a Foley catheter and a urinary collecting bag. During the procedure, values of the intra abdominal pressure are displayed on a monitor next to anaesthetic machine in real time. The numbers representing the pressure in mmHG are assessed and recorded.Discussion: Possible correlation between intra abdominal hypertension and postsurgical complications in patients operated in prone position could be a foundation to further clinical trials and presurgical assessment of intraabdominal pressure.
