Sensory and motor blockade during spinal anaesthesia with 0.75% and 0.5% ropivacaine – A double-blind study

Abstract

Background: Spinal anaesthesiaproduces intense sensory and motor blockade as well as sympathetic blockade. Ropivacaine is a long-acting regional anaesthetic that is structurally related to Bupivacaine. It is developed for the purpose of reducing potential toxicity and improving relative sensory and motor block profiles. This study was undertaken to determine sensory and motor blockade profiles for 0.5% and 0.75% ropivacaine given intrathecally for perineal and lower limb surgeries. Material and Methods:A total of 100 patients were randomly divided into two equal groups. Group I received 0.5% and Group II received 0.75% isobaric Ropivacaine. After spinal anesthesia, sensory and motor blocks were assessed by pin prick test and Bromage scale respectively. Results: The results of our study indicate dose dependency. In both sensory and motor blockade cases, onset was quicker, intensity greater, regression slower, and duration longer with increasing concentrations. Conclusion: Intrathecal administration of 0.75% isobaric ropivacaine produced better quality of analgesia and motor block with negligible hemodynamic disturbances as compared to 0.5% ropivacainein perineal and lower limb surgeries.
