Effect of Injection Duration of Fascial Plane Blocks on Block Success
Sponsor: Bursa Yuksek Ihtisas Training and Research Hospital
Summary
This prospective observational study aims to evaluate the impact of injection duration during fascial plane blocks on block success and analgesic efficacy in patients undergoing laparoscopic cholecystectomy. The hypothesis is that shorter injection durations increase injection pressure, potentially limiting local anesthetic spread, while longer durations facilitate broader anesthetic distribution.
