Abstract
Background: In this study, we wantedto compare the effectiveness of intrathecal Hyperbaric Ropivacaine with fentanyl and Hyperbaric Bupivacaine with fentanyl in perineal surgeries, to sensory block and motor block. We also compared the changes in blood pressure, heart rates and complications.Materials and methods: This was a hospital based non-randomised control comparative study conducted among 40 patients posted for perineal surgeries to Osmania General Hospital, Afzalgunj, Hyderabad, over a period of 24 months after obtaining clearance from Institutional Ethics Committee and written informed consent from the study participants.
Results: The minimum and maximum (time of onset of motor blockade) TOM was 2 and 3 minutes in group ‘A’ and 1 and 2 minutes in group ‘B’. The mean ± SD TOM is 2.5 ± 0.51 minutes in group ‘A’ and 1.6 ± 0.51 minutes in group ‘B’. There was significant difference between two groups A and B for the parameter time of onset of motor blockade. The minimum and maximum duration of sensory blockade (DOS) was 132 and 172 minutes in group ‘A’ and 96 and 140 minutes in group ‘B’. The mean ± SD DOS is 153.4 ± 11.94 minutes in group ‘A’ and 112.0 ± 13.86 minutes in group ‘B’. There was significant difference between two groups A and B for the parameter DOS (in minutes). The minimum and maximum DOM was 165 and 198 minutes in group ‘A’ and 120 and 170 minutes in group ‘B’. The mean ± SD duration of motor blockade (DOM) was 185.2 ± 9.21 minutes in group ‘A’ and 155.8 ± 13.79 minutes in group ‘B’. There was significant difference between two groups A and B for the parameter DOM (in minutes).
Conclusion: Hyperbaric ropivacaine achieves a lesser duration of sensory and motor blockade, and lesser degree of motor blockade when compared with hyperbaric bupivacaine. Hence, hyperbaric ropivacaine with fentanyl in spinal anaesthesia is a better alternative for perineal day care surgeries
