Spinal versus general anesthesia in gynecologic laparoscopy: A prospective, randomized study

To compare spinal anesthesia (SA) with general anesthesia (GA) in gynecologic laparoscopic surgery regarding anesthetic parameters and patient satisfaction together with an assessment of total oxidant, antioxidant levels, and Oxidative Stress index (OSI).

Sixty patients who were planned to undergo gynecologic laparoscopy were randomized into group G (GA) and group S (SA). Demographics, adverse events and anesthetic parameters were recorded before induction, after induction, and at the 5^th, 10^th, 15^th, 30^th, 60^th, 90^th, and 120^th minutes. Patients and surgeons completed questionnaires. Total antioxidant capacity (TAC), total oxidant level (TOL), and OSI were measured.

There was no difference between the groups in terms of hemodynamic parameters except heart rate at 30^th minute and mean arteral pressure at 10^th, 15^th, 30^th, and 60^th minute (p<0.05). The postoperative arterial blood pH value was lower in group S (p=0.021). Intraoperative hypotension was lower in group S (p=0.038). There was more intraoperative hypotension in group S when compared with group G (p=0.038). Postoperative analgesic consumption was higher and onset of postoperative pain was shorter in group G (p=0.001 for both). There was no difference between the groups in terms of patient and surgeon satisfaction. There was no difference in terms of TAC, TOL, and OSI between the groups (p=0.862, p=0.940, and p=0.728, respectively).

SA may become a reliable alternative to GA in gynecologic laparoscopy when hemodynamic and respiratory parameters, patient and surgeon satisfaction, as well as total oxidant, antioxidant levels, and OSI are considered.
