Abstract

Objective: To compare the effectiveness in term of postoperative analgesia of intrathecal bupivacaine and intrathecal tramadol as an adjuvant to hyperbaric bupivacaine in patients undergoing infraumbilical surgeries. Study Design: Prospective double-blinded randomized Place & Duration: Department of surgery, Khairpur Medical College (KMC) Hospital, Khairpur Mirs for duration of six months from February 2020 to July 2020.

Methods: This research involved a total of 100 patients. The patient's age was from 20 to 65. The two equal classes of patients have been separated. Group I had 50 patients who received intrathecally 10 mg 0.5% bupivacaine and 30 mg tramadol while in group II (n=50) received bupivacaine 10 mg 0.5% with 50 μg buprenorphine. Time to block T10 with the 25G blunt needle. comparison between the two groups were evaluated by pin prick process. SPSS 24.0 version of the full data has been analyzed.

Results: Mean age of the patients in group I was 41.84 ± 6.33 years with mean body mass index 27.84 ± 6.33 while in group II mean age was 41.94 ± 9.68 years with BMI 26.84 ± 8.78.Mean VAS scores were greater in group II as compared to group I. Mean onset time for sensory block was earlier in group II (3min) as compared to group I (3.4min). Mean onset time for motor block in group II was earlier (5.1min) as compared to group I (5.6min) with p value 0.005. Mean time for rescue analgesia was higher in group I (5.24 ±5.3h) as compared to group II (4.98±4.9h). No significant difference was observed between both groups.

Conclusion: We concluded in this study that bupivacaine with buprenorphine showed less duration of time for postoperative analgesia in infraumbilicalsurgeriesa as compared to tramadol. Keywords: Spinal, Anesthesia, Post-operative analgesia, Tramadol, Buprenorphine
