Despite its minimally invasive nature, surgical stimulation and pneumoperitoneum may cause pain-related physiological and neurophysiological responses during general anesthesia.\n\nThis prospective observational study will evaluate patients undergoing laparoscopic cholecystectomy under general anesthesia. Patients will be observed according to the analgesic technique selected by the attending anesthesiologist as part of routine clinical care: intravenous remifentanil alone or remifentanil combined with an ultrasound-guided subcostal transversus abdominis plane (TAP) block.\n\nThe study will examine the relationship between the use of subcostal TAP block and intraoperative analgesic requirements, Bispectral Index (BIS) values, electroencephalographic (EEG) dynamics, and burst suppression. Postoperative pain scores, additional analgesic requirements, quality of recovery, mobilization time, length of hospital stay, and patient satisfaction will also be evaluated.",[24,25,26],"Laparoscopic Cholecystectomy","Postoperative Pain","Intraoperative Nociception",[28,29,30,31,32,33,34,35,36,37,38,39],"Subcostal TAP Block","Transversus Abdominis Plane Block","Electroencephalography","EEG","Bispectral Index","BIS","Burst Suppression","Intraoperative Analgesia","Multimodal Analgesia","Remifentanil","Nociception","Quality of Recovery","RECRUITING","2026-09-11",{"date":43,"type":44},"2026-09-14","ACTUAL",{"date":46,"type":44},"2026-07-15",{"date":48,"type":20},"2026-12-31",{"name":50,"class":51},"Sehit Prof. Dr. Ilhan Varank Sancaktepe Training and Research Hospital","OTHER"]
