简要总结
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.
详细描述
Fascial plane blocks involve injecting local anesthetics between two anatomical fascial layers, with analgesia achieved by anesthetic diffusion through the fascial plane. However, anesthetic spread may vary significantly based on injection technique, speed, and pressure. This study hypothesizes that injection duration directly influences injection pressure, local anesthetic distribution, and consequently, the extent of sensory blockade and analgesia.

研究组 & 干预措施
Conventional
During the fascia block application, the injection will be administered using the conventional method without any specific time limit.
干预措施: Group C (Drug)
One-minute injection
During the fascia block application, the injection will be administered within 1 minute.
干预措施: Group O (Drug)
Two-minute injection
During the fascia block application, the injection will be administered within 2 minutes.
干预措施: Group T (Drug)
结局指标
主要结局
sensory block distribution
时间窗: Postoperative 24 hours
The distribution of sensory block will be evaluated using pinprick and cold tests at 2, 6, 12 and 24 hours after surgery. With the pinprick, the gently touches the skin with the pin or back end and asks the patient whether it feels sharp or blunt.
次要结局
- NRS(Postoperative 24 hours)
- tramadol consumption(Postoperative 24 hours])
- Pressure values(During the procedure)
