How Injection Time Affects Block Success in Gallbladder Surgery
Official title: Effect of Injection Duration of Fascial Plane Blocks on Block Success and Postoperative Analgesia in Patients Undergoing Laparoscopic Cholecystectomy
Run by Bursa Yuksek Ihtisas Training and Research Hospital · NCT07096765 · Data updated 2026-11-12
This study tests whether the speed of injecting anesthetic in fascial plane blocks changes how well the block works for people having laparoscopic gallbladder removal.

Is this trial a fit for you?
✓Likely a good fit
Candidates are adults undergoing laparoscopic cholecystectomy with ASA I or III, and without major comorbid conditions.
✕Probably not a fit
Patients with uncontrolled hypertension, diabetes, metabolic disorders, bleeding disorders, BMI over 30, or other excluded conditions may not benefit.

What this trial studies
This prospective observational study examines how different injection durations for fascial plane blocks influence block success and postoperative pain control in patients undergoing laparoscopic cholecystectomy. Researchers compare groups with varying injection times to see how time affects injection pressure and the spread of local anesthetic within the fascial plane. The goal is to understand whether slower injections allow wider anesthetic distribution and better analgesia, or if faster injections limit spread and success. The study will correlate technique variables with sensory blockade and analgesic outcomes. It is conducted at Bursa Yuksek Ihtisas Training and Research Hospital.
Why it matters
Potential benefit: If longer injection durations improve block spread, patients could experience better pain relief after surgery.
How similar studies have gone: Previous work suggests injection technique and spread influence block efficacy, but this targeted look at duration and pressure is relatively novel.
