Clinical Trial Summary

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Increase in intra abdominal pressure during surgery.	Change in intra abdominal pressure during surgery in prone position.	Intraoperative
Secondary	Correlation of increased abdominal pressure with renal dysfunction assessed by creatinine.	Assessment of renal function in labolatory tests: creatinine change (mg/dl).	From start to eight hours after the surgery.
Secondary	Correlation of increased abdominal pressure with renal dysfunction assessed by urea.	Assessment of renal function in labolatory tests: urea change (mg/dl).	From start of surgery to eight hours after the surgery.
Secondary	Correlation of increased abdominal pressure with renal dysfunction assessed by potassium.	Assessment of renal function in labolatory tests: potassium change (mg/dl).	From start of surgery to eight hours after the surgery.
Secondary	Correlation of increased abdominal pressure with mioglobin.	Assessment in labolatory tests: mioglobin change (mg/dl).	From start of surgery to eight hours after the surgery.
