Intraabdominal Pressure Monitoring Urinary Catheter and Kidney Perfusion Pressure

Use of an Intraabdominal Pressure Monitoring Urinary Catheter After Cardiac Surgery to Improve Kidney Perfusion Pressure: A Randomized Controlled Trial

The goal of this clinical trial is to determine whether monitoring intra-abdominal pressure (IAP) and adjusting blood pressure accordingly to maintain optimal renal perfusion pressure can reduce the risk of acute kidney injury (AKI) after cardiac surgery.

The main question this study aims to answer is:

- Does IAP-guided blood pressure management improve renal perfusion and lower AKI rates in cardiac surgery patients?

Participants will be randomly assigned to one of two groups:

• Control Group: Standard ICU care with a conventional Foley catheter.
• Intervention Group: Standard ICU care with an IAP-monitoring Foley catheter, where blood pressure is adjusted based on IAP readings to optimize renal perfusion pressure.

All participants will undergo routine blood and urine tests to assess kidney function during their hospital stay.

This study will help determine whether IAP-based hemodynamic management can improve postoperative kidney outcomes and provide a new strategy for AKI prevention in cardiac surgery patients.
