Comparison of general anesthesia with spinal anesthesia in laparoscopic cholecystectomy operations

Abstract

Objective: Laparoscopic cholecystectomy (LC) operations are being performed under general anesthesia (GA). Further studies are needed on the issue whether these operations can be performed under spinal anesthesia (SA). In this study we aimed to compare SA with (GA) in terms of efficacy and complications in patients who will undergo LC operations, and to investigate the effects of preemptive analgesia on the development of shoulder pain, transition to general anesthesia, and postoperative analgesia. Method: Sixty patients in ASA I-II risk group between 18-65 years of age undergoing laparoscopic cholecystectomy were randomly divided into general anesthesia (GA, n=30) and spinal anesthesia (SA, n=30) groups. Patients were premedicated with i.v. midazolam and fentanyl preoperatively. Anesthesia was induced with propofol in the GA group, and maintained with Desflurane and remifentanil. In the SA group, spinal anesthesia was provided with intratechal administration of 15 mg bupivacaine at L2-3 level, and block level was increased to T4 by keeping the patient in Trendelenburg position for 7-10 minutes. Demographic data, hemodynamic parameters, operation time, visual analog scale (VAS) scores at postoperative 0th,1st, 4th, 8th,12th and 24th hours, patient-surgeon satisfaction, side effects, and occurrence of right shoulder pain in SA group were inquired and recorded. Results: Effective anesthesia was produced in both groups. Hypotension was observed in 5, bradycardia requiring atropin administration in 4, and perioperative shoulder pain in 9 patients in Group SA, but none of them required general anesthesia. Hypotension developed in one patient in Group GA. The postoperative VAS scores were significantly lower in Group SA at 0th,1st, 4th hours. Patient satisfection scores were higher in Group SA. Conclusion: We concluded that spinal anesthesia may be an alternative method to general anesthesia in patients who will undergo laparoscopic cholecystectomy operations especially when the risk of general anesthesia is too high. © Istanbul Medeniyet University Faculty of Medicine.
