Abstract :

 Background: In this study, we compared the efficacy of Ropivacaine with Bupivacaine to determine the suitability of each agent for interscalene achial plexus block. Sixty patients undergoing elective orthopaedic upper limb surgery were divided into two groups. They were named as Group–R and Group–B. Group–R received 30 ml of Ropivacaine Hydrochloride 0.5% and Group–B received 30ml of Bupivacaine Hydrochloride 0.5%. Sensory and motor block onset time, duration of motor block, and duration of analgesia (VAS) were assessed during intra operative period and post operative period. Visual Analog Scale (VAS) scores were recorded at 0, 30 min, 45 min, 1 hr, 2hr, 3hr at regular one hour intervals up to 12 hrs and side effects were noted. Statistical Analysis: The observations obtained were recorded and tabulated. Statistical analysis was carried out using Students t–test and Chi–square test. Results: Onset time of sensory and motor block was shorter in Group–B when compared to Group–R and statistically not significant (p > 0.05). The duration of motor blockade was longer in Group–R and also statistically significant compared to Group–B ( p < 0.05). The duration of analgesia in Group–R was longer compared to Group–B and also statistically significant ( p < 0.05). We found that the patients who received Ropivacaine 0.5% had longer duration of motor blockade and longer duration of analgesia than the patients who received Bupivacaine 0.5%.
