ClinConnect Summary

This clinical trial is studying a way to reduce pain after gallbladder removal surgery done through small cuts in the belly, called laparoscopic cholecystectomy. Although this surgery has many benefits, patients often experience significant pain afterward, which can make recovery harder. The study is testing whether using a nerve block called the erector spinae plane block (ESPB) on one side of the back with a larger amount of numbing medicine can better control pain after surgery. Researchers want to see if a higher volume of this medicine spreads more widely and provides better pain relief, possibly even affecting both sides of the body.

Adults between 18 and 60 years old who are generally healthy, with a normal weight range and no serious medical problems, may be eligible to join. If you participate, you will receive this nerve block on the right side of your back during surgery, and the study will measure your pain levels up to 12 hours afterward. People who have allergies to numbing medicines, bleeding problems, serious heart or lung issues, or certain other health conditions would not be able to join. This trial is not yet recruiting but aims to find a safer and more effective way to reduce pain and help patients recover more comfortably after gallbladder surgery.
