ABSTRACT
Background: 0.5% heavy bupivacaine is one of the commonest drugs used intrathecally for spinal anaesthesia. Opioids are commonly used as adjuvants with local anaesthetics. We compared butorphanol as an adjuvant to local anaesthetic agent and local anaesthetic alone in subarachnoid block in infraumbilical surgeries.
Aim: To evaluate how efficacious is butorphanol as an additive to bupivacaine intrathecally in infraumbilical surgeries in terms of haemodynamic stability.
Methodology: The study was done on sixty patients of ASA I & II between 18-65 years posted for elective infraumbilical surgeries and two equal groups were made. In Group A patients received bupivacaine 0.5% ( 2.5 ml ie 12.5 mg) + 0.5 ml normal saline (total volume 3ml)intrathecally and in Group B they received bupivacaine 0.5% ( 2.5 ml ie 12.5mg) + injection butorphanol 25 microgram (1 mg/ml of preservative-free injection butorphanol which was diluted to 20 ml by normal saline , 0.5 ml of this solution was taken) making total volume 3 ml intrathecally. Haemodynamic parameters were summarized and compared between both the groups.
Results: A statistically significant decrease in mean arterial blood pressure occurred in Group A in comparison to Group B. However, patients didn’t require any clinical intervention.
Conclusion: Addition of injection butorphanol with bupivacaine gives haemodynamic stability as compared to bupivacaine alone intrathecally.
