Comparing methods for managing blood pressure during heart surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This trial aims to evaluate different strategies for managing Mean Arterial Pressure (MAP) during cardiopulmonary bypass (CPB) in cardiac surgery. It will be the first multicenter, randomized, controlled study to compare three distinct MAP management approaches to determine the most effective strategy for maintaining organ perfusion and preventing postoperative complications. The study will include patients undergoing elective heart surgeries with specific eligibility criteria, ensuring a controlled environment for assessing outcomes. By analyzing the effects of varying MAP levels, the trial seeks to establish updated guidelines for CPB management based on contemporary practices and technologies.
