ClinConnect Summary

This clinical trial is looking at a new way to help doctors place a small tube, called a catheter, into a vein during heart surgery. Usually, doctors use ultrasound (a type of imaging that uses sound waves) to guide them, but this study is testing whether adding a laser tool can make it easier and more successful on the first try. The goal is to see if this laser-assisted method helps doctors insert the catheter more quickly and accurately compared to the traditional ultrasound method.

Adults between 18 and 80 years old who are having heart surgery and meet certain health criteria, such as a healthy weight range and a specific health status, may be able to take part. People with infections or bruises where the catheter would go, those who can’t cooperate with the procedure, or those who don’t want to join won’t be able to participate. If you join the study, you’ll experience the usual catheter placement but with either the laser-assisted or traditional ultrasound guidance, and the doctors will check which method works better. This study hasn’t started recruiting participants yet, but it could help improve care for future patients undergoing heart surgery.
