This study aims to compare the effects of intraoperative intravenous lidocaine and intravenous remifentanil on postoperative pain management in patients undergoing laparoscopic cholecystectomy under general anesthesia. Although laparoscopic procedures are minimally invasive, patients frequently experience postoperative pain. Multimodal analgesia techniques are recommended to optimize pain control and recovery while minimizing opioid-related adverse effects.
In this prospective observational study, adult patients (ASA I-II) aged over 18 years who provided written informed consent were included. Standard intraoperative monitoring was performed. Anesthesia induction consisted of fentanyl, lidocaine, propofol, and rocuronium, with maintenance using sevoflurane. Hemodynamic parameters were recorded throughout the procedure. For postoperative analgesia, intravenous paracetamol and tramadol were administered before the end of anesthesia.
The primary objective is to evaluate whether intravenous lidocaine provides postoperative analgesic efficacy and recovery quality comparable to remifentanil, and to determine its potential role as an opioid-sparing alternative in laparoscopic cholecystectomy.
