Clinical Trial: Comparison of ANI Between Preoperative and Postoperative Ultrasound-guided TAP Block in Laparoscopic Cholecystectomy

U.S., Sept. 10 -- ClinicalTrials.gov registry received information related to the study (NCT07809009) titled 'Comparison of ANI Between Preoperative and Postoperative Ultrasound-guided TAP Block in Laparoscopic Cholecystectomy' on Sept. 02.

Brief Summary: The goal of this clinical trial is to learn if the timing of ultrasound-guided transversus abdominis plane block (US-TAP block) administration (preoperative vs. postoperative) affects the perioperative analgesia nociception index (ANI) in adult patients undergoing laparoscopic cholecystectomy. The main questions it aims to answer are:

* Does the timing of the US-TAP block significantly influence intraoperative ANI values?

* Does the difference in US-TAP block timing and subsequent ANI v...
