“Comparison of Post Operative Analgesic Effect of Intraarticular Bupivacaine and Ropivacaine in Day Care Arthroscopic Knee Surgery.”

Abstract

Purpose: Intra-articular administration of local anesthetic drugs provides analgesia after arthroscopic knee surgery. Study was comparison of the analgesic effect of intraarticular injection of ropivacaine and bupivacaine in patients undergoing arthroscopic surgery. Double- Type of Study: blind, randomized prospective clinical study. The study included patients schedul Methods: ed for knee meniscus repair under arthroscopy divided into 2 groups to receive, intra-articularly, 30 mL of bupivacaine 0.5%(150mg), or ropivacaine 0.75%(225) solutions at the end of surgery. Postoperatively, pain was measured using a visual analog scale (VAS). Paracetamol was given when patients complained of pain. VAS Results: scores were higher in the bupivacaine group compared with the ropivacaine group. Duration of postoperative analgesia and paracetamol administration was shorter in the bupivacaine group compared with the ropivacaine group. Paracetamol consumption was signicantly lower (P < .004) during the rst 24 hours in the ropivacaine group (4.00 ± 1.37) than in the bupivacaine groups (6.89 ± 1.711) : This study Conclusions documents that intra-articular ropivacaine 0.75% provides better analgesia than bupivacaine 0.5% after knee arthroscopic surgery
