ABSTRACT
To compare the efficacy of spinal anaesthesia with general anaesthesia for lumbar discectomy in terms of theatre time and post-operative effects. Randomized controlled trial. Neurosurgery department Combined Military Hospital Rawalpindi, from November 2013 to April 2014. A total 60 consecutive patients with herniated lumbar discs were enrolled in this study to undergo randomly into assigned spinal anaesthesia group SA [n=30, group A] or General anaesthesia GA [n=30, group B].Variables included age, gender, level of lumbar disc prolapse, type of anaesthesia, operative time, and combined total theatre time, post-operative pain using visual analogue scale [VAS] and hospital stay in days. Mean theatre time in group A was 62.70 and for group B it was 90.73 [p<0.001]. The mean hospital stay after surgery in group A was 2.0 days and in group B was 2.27 days [p< 0.002]. Peak post- operative pain scores according to visual analogue scale and resultant analgesic requirements in group A was 5.10 while for group B it was 6.87 p< 0.001. Spinal anaesthesia is safe and can be routine anaesthesia for most of the patients undergoing lumbar discectomy
