Evaluation of Supraclavicular Brachial Plexus Blocks At Various Volumes: Impact on Optic Nerve Sheath Diameter

Launched by PAMUKKALE UNIVERSITY · May 22, 2024

ClinConnect Summary

This clinical trial is studying a type of anesthesia called supraclavicular brachial plexus blocks, which is used to numb the arm and shoulder area during surgery. Researchers want to find out how effective this method is at different volumes, how well it works for pain relief after surgery, and if it causes any side effects. They will also use ultrasound, a special imaging technique, to check the size of the optic nerve sheath, which can help understand changes in pressure inside the brain related to this anesthesia technique.

To participate in the trial, you need to be between 18 and 50 years old and scheduled for surgery on your finger, wrist, or elbow. You should be generally healthy, classified as ASA I or II, which means you're not seriously ill. If you agree to join, you'll be informed about the anesthesia method and the tests involved and will need to sign a consent form. It's important to know that certain health conditions, like severe heart problems or recent heart attacks, might exclude you from participating. If you decide to take part, you can expect to receive detailed information about the procedures and what to expect during the study.
