Ultrasound Guidance Radial Artery

ClinConnect Summary

This clinical trial is studying a new way to safely and accurately insert a catheter into the radial artery, which is located in your wrist. The researchers will use ultrasound, a type of imaging that uses sound waves, to help find the best spot for the catheter. This method aims to lower the number of attempts needed to insert the catheter, minimize any complications, and make the procedure safer for patients undergoing surgery that requires monitoring of blood pressure.

To participate in this trial, you need to be a surgical patient aged 18 to 65 who will receive general anesthesia. You should also be in good health (graded as ASA I or II) and willing to sign a consent form to join the study. However, if you have certain conditions like issues with blood flow, local skin infections, or previous nerve injuries, you may not be eligible. If you choose to participate, you can expect to have your ultrasound assessment done before the catheter insertion, which will help guide the medical team to reduce risks during the procedure.
