COMPARISON OF TWO STRENGTHS OF BUTORPHANOL ADDED TO HYPERBARIC BUPIVACAINE GIVEN INTRATHECALLY IN LOWER ABDOMINAL OR LOWER LIMB SURGERY

Abstract :

Aims and objective : To evaluate the effects of addition of two strengths (25 mcg and 50 mcg) of Butorphanol to hyperbaric Bupivacaine on the onset, quality and duration of sensory and motor blockade when administered intrathecally and compare them with control group.To observe the side effects (if any) of Butorphanol when administered intrathecally with hyperbaric Bupivacaine in two different doses.

Methodology:The study was conducted in 60 patients belonging to ASA grade I & II, of either sex and age undergoing subarachnoid block for elective surgeries of 1 – 2 hours duration.Prior permission of Institutional Ethical Committee (IEC) was obtained to conduct the study.Informed consent was obtained from all the patients.All the patients were subjected to thorough pre – anaesthetic evaluation and relevant laboratory investigations.

Results: All the three groups were comparable with respect to the patient’s demographic profile.The onset of sensory block did not show any significant difference statistically in all the three groups: Group A control (16.1 ± 6.90sec), Group B Butorphanol 25mcg (18.4 ± 8.25sec), Group C Butorphanol 50mcg (17.75 ± 7.64sec)The motor block was slightly delayed in group B & C (32 ± 8.64 & 28.25 ± 7.30 sec) as compared to control group (23.1 ± 8.01sec), which is practically acceptable.

Conclusion. Thus we conclude from our study that Intrathecal Butorphanol potentiates bupivacaine induced sensory spinal block and reduces the analgesic requirement in the early postoperative period without prolonging motor block recovery time to micturition and without any other major side effects.
