Comparative study of hyperbaric bupivacaine 0.5% versus hyperbaric bupivacaine 0.5% and fentanyl in spinal anaesthesia for lower abdominal and lower extremity surgeries

Abstract

The study was conducted to compare the differences in the onset, duration of action of intrathecal hyperbaric bupivacaine 0.5% (group-I) versus intrathecal hyperbaric bupivacaine 0.5% and fentanyl 25 mg (group-II) in spinal anaesthesia in lower abdominal and lower extremity surgeries. The combination of bupivacaine and fentanyl helps anaesthesiologist to alleviate intraoperative discomfort by providing better analgesia to the patients without prolonging recovery. 100 patients belonging to ASA grade-I and II of both the sexes (n=50 in each group) were randomly selected for the study. The time of onset of sensory and motor block, duration of analgesia, 2-segment regression, intraoperative discomfort, time to micturition, visual analogue score, post operative analgesic requirements were assessed. The time of onset of sensory and motor block were significantly longer in group-II than group-I (P
