| Popis: | Background & Objective: Hyperbaric bupivacaine is the most commonly used local anesthetic for spinal anesthesia, alone or in combination with various adjuvants. Opioids are frequently used for their rapid onset and intense block characteristics. Fentanyl is the preferred intrathecal opioids with rapid onset of action but has a shorter duration of action. Buprenorphine is a mixed agonist-antagonist with high affinity at both mu and kappa opioid receptors. We compared administration of buprenorphine with fentanyl as adjuvants with intrathecal hyperbaric bupivacaine in gynecological surgeries. Methodology: After Institutional Ethical Committee approval and written informed consent, 60 patients aged 18–65 y, scheduled for lower abdominal gynecological surgery, were divided into two equal groups; Group F to receive 0.5% hyperbaric bupivacaine 2.5 ml with fentanyl 25 µg intrathecal and Group B to receive 0.5% hyperbaric bupivacaine 2.5 ml with buprenorphine 75 µg intrathecal. Block characteristics and associated side effects were compared between two groups. The data was analyzed using Chi square test and Fisher’s exact test. For comparing two group of mean, independent student’s t test was used. P-value < 0.05 was considered as statistically significant. Results: The mean onset of sensory and motor block was significantly earlier in Group F than Group B (p < 0.001). Mean duration of sensory block was significantly prolonged in Group B compared to Group F (p < 0.05). Whereas, the duration of motor was comparable in both of the groups (p > 0.05). Duration of analgesia was significantly prolonged in Group B than Group F (p < 0.001). Conclusion: We conclude that when a longer duration of postoperative pain relief is needed, buprenorphine can be a suitable drug to be used with intrathecal hyperbaric bupivacaine for gynecological surgeries because of prolonged duration of action.
