Randomized Controlled Trial
Efficacy of 0.5% Hyperbaric Bupivacaine with Dexamethasone versus 0.5% Hyperbaric Bupivacaine alone in Spinal Anaesthesia for Patient Undergoing Lower Abdominal Urological and Lower Limb Orthopedic Surgeries.
Spinal anaesthesia with local anaesthetics has limited duration. Different additives have been used to prolong spinal anaesthesia. The aim of this study was to determine the efficacy of adding dexamethasone to bupivacaine in spinal anaesthesia specially whether it would prolong the duration of sensory block/ surgical analgesia and post-operative analgesia/pain free period or not. ⋯ The duration of post-operative analgesia/pain free period was 208.78±41.57 minutes in the bupivacaine group; whereas it was 412.82±71.51 minutes in the bupivacaine-dexamethasone/case group which was also statistically highly significant (p<0.001). The frequency of complications was not different between two groups. This study has shown that the addition of dexamethasone to bupivacaine in spinal anaesthesia significantly improved the duration of sensory block/surgical analgesia as well as post-operative analgesia/pain free period without any complications.
