Background: To enhance the duration of sensory anaesthesia and to prolong the duration of post-operative pain relief during spinal anaesthesia, various adjuvants have been tried along with local anaesthetic agent. The present study was undertaken to evaluate and compare the onset and duration of sensory block, motor block and duration of post-operative pain relief by using intrathecal 0.5% Hyperbaric bupivacaine with fentanyl 25µg versus only 0.5% Hyperbaric bupivacaine selected groups.
Methods: We enrolled 70 ASA Ι & ΙΙ patients undergoing surgeries below umbilicus level for our Prospective Randomized trial. Those who met our inclusion criteria were randomized using simple random sampling technique, after obtaining informed consent. Patients in Group A received fentanyl 25µg with 0.5% Hyperbaric Bupivacaine and patients in Group B received only 0.5% Hyperbaric Bupivacaine intrathecally. Parameters like onset and duration of sensory and motor block and postoperative pain relief were observed. In postoperative period, VAS score was monitored & time for rescue analgesia was noted, when VAS exceeded 5 or above.
Results: It was found that Patients in Group A had significantly prolonged duration of postoperative analgesia as compared to Group B (Z value 17.35). Results of Onset & Duration of sensory and motor block were suggesting insignificant result. Post-operative complication was insignificant in our study.
Conclusion: Addition of Fentanyl 25µg with 0.5% Hyperbaric Bupivacaine in Spinal anaesthesia have insignificant effect on duration of sensory and motor blockade and prolongs postoperative pain relief.
