Femoral Versus Radial Invasive Arterial Pressure Monitoring in Cardiac Surgery Patients

ClinConnect Summary

This clinical trial is investigating the best way to monitor blood pressure during and after heart surgery. Doctors often use two different arteries for this: the radial artery in the wrist and the femoral artery in the groin. The goal of this study is to find out if using the femoral artery provides more accurate blood pressure readings than the radial artery, which could help reduce the need for medication called norepinephrine that is used to raise blood pressure. Accurate blood pressure monitoring is crucial for patients undergoing major surgeries, as it can help prevent complications after surgery.

To participate in this study, patients must be adults aged 18 to 80 who are scheduled for elective heart surgery. They will be randomly assigned to either the radial or femoral artery monitoring group. Throughout the study, participants will have their blood pressure monitored continuously, and doctors will track any complications or health issues that arise in the first week after surgery. This research could provide important information on how to improve patient care during heart surgery, potentially leading to better outcomes and fewer complications.
