Intraabdominal Hypertension, Prone Postion, Spine Surgery
Conditions
Brief 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.

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