Introduction:
Spinal anaesthesia is the most common neuraxial block used in surgical setting. The main advantage is the high success rate, safety record, rapid onset, predictable duration, minimal side effect and reliable offset. Study aimed to compare Levobupivacaine and Levobupivacaine with Butorphanol in terms of onset of sensory and motor blockade, duration of sensory and motor block, two segment regression time, hemodynamic changes, time for first rescue analgesia and complications in infraumbilical surgeries.
Materials and methods: 60 patients of ASA class 1 and 2 of age between 19 to 65 years were selected in the study and divided them into two groups with 30 patients each.
Group A - 15 mg (3 ml) of 0.5% Levobupivacaine + 0.1 ml Normal saline.
Group B- 15 mg (3 ml) of 0.5% Levobupivacaine + 100 g (0.1 ml) of Butorphanol.
All groups received drug at L2-L3 intervertebral space.
Result: On comparing both the groups, the duration of sensory and motor blockade was more in group B. The two-segment regression time was more isn group B and the time for the first rescue analgesia was also more in group B. Hemodynamic stability was achieved in group B with minimal change in the parameters and with fewer complications.
Conclusion: we concluded that addition of injection Butorphanol with Levobupivacaine gives hemodynamic stability as compared to Levobupivacaine alone intrathecally and also provides longer duration of sensory and motor blockade and superior analgesia than intrathecal levobupivacaine alone.
