Background And Aim:
General anesthesia (GA) is the most commonly used anesthetic technique for spinal surgery. This study aimed to compare spinal anesthesia (SA) and GA in patients undergoing spinal surgery, in terms of perioperative outcome and cost effectiveness.
Materials And Methods:
The study included 80 patients with ASA (American Society of Anesthesiologists) physical status I-II. The patients were randomized to receive SA (n = 40) or GA (n = 40). Heart rate (HR), mean arterial blood pressure (MABP), blood loss, duration of surgery, duration of anesthesia, surgeon satisfaction, and duration in the post-anesthesia care unit (PACU) were recorded. Postoperative analgesic requirement, nausea and vomiting (PONV), perioperative hemodynamic variables, and anesthetic costs were determined.
Results:
HR and MABP were significantly higher in the GA group than in the SA group at the end of surgery and at PACU admission. Duration of anesthesia, surgeon satisfaction, postoperative analgesic requirement, and anesthetic costs were significantly higher in the GA group. Mean blood loss was lower in the SA group than in the GA group, but the difference was not significant. Duration of surgery, duration in the PACU, perioperative hemodynamic variables, and complications were similar in both groups.
Conclusions:
SA could be considered a reliable alternative to GA in patients undergoing lumber spine surgery, as it is clinically as effective as GA, but more cost effective.
