ClinConnect Summary

This clinical trial is studying two different methods of providing anesthesia for surgeries on the upper arm and hand. Researchers want to compare the effectiveness of a technique called selective trunk block (SeTB) to a more commonly used method known as supraclavicular brachial plexus block (BPB). They believe that SeTB may do a better job of numbing the entire arm, from the shoulder down to the hand, without causing certain side effects that can occur with the BPB method.

To participate in this trial, individuals aged between 18 and 75 who are scheduled for either elective or emergency surgery on their upper extremity may be eligible. However, some people may not qualify if they are pregnant, have certain skin infections, or have specific health issues such as respiratory problems or an allergy to local anesthesia. Participants can expect to receive either of the two anesthesia techniques during their surgery, and the study aims to gather important information on how well each technique works. Overall, this research could help improve pain management for future patients undergoing similar surgeries.
