Abstract

The aim of the study is to Comparison of nalbuphine hydrochloride and fentanyl as an adjuvant to bupivacaine for spinal anaesthesia in lower limb surgeries. Patient was inquired for 6 hours fasting period. I.V access was established using an 18 gauge cannula and a fluid ringer lactate 10-15ml/kg body weight was given as preload over 20-25 min prior to subarachnoid block. Inj ondansateron 8 mg was given to every patient. Oxygen via facemask was administered if needed during anaesthesia and surgery. Results: Duration of motor blockade was 218.33 min in BN group and 223.4 min in BF group.It was significantly higher among participants of BF group compared to that of participants in BN group. Duration of sensory blockade among group BF was 237.53 min and in group BN was 227.6 min. Duration of sensory blockade was significantly higher among participants of BF group compared to that of participants in BN group Conclusion: Comparison between intrathecal fentanyl and intrathecal nalbuphine concluded that Intrathecal fentanyl is a good alternative to nalbuphine which provides long duration of sensory and motor blockade in lower limb surgeries. Duration of analgesia in intrathecal nalbuphine is prolonged as compared to intrathecal fentanyl as adjuvants hence it may be used with better results in lower limb surgeries for post-operative analgesia.
