Background: Post-operative pain frequently hampers implementation of day care arthroscopic knee surgery in spite of so many analgesic, local anesthetic drugs and routes of administration. Aims: The aim of the present study was carried out to compare the efficacy of ropivacaine and levobupivacaine when administered through intra-articular route in controlling pain after day care arthroscopic knee surgery. Setting and Design: It was a prospective, double-blinded and randomized controlled study. Materials and Methods: April 2008-December 2008, 60 patients of both sex, of American Society of Anesthesiologists physical status I and II, undergoing day care arthroscopic knee surgery were randomly assigned into two groups (R, L). Group R received 10 ml of 0.75% ropivacaine, whereas group L received 10 ml of 0.50% levobupivacaine through intra-articular route at the end of the procedure. Pain assessed using visual analog scale (VAS) and diclofenac sodium given as rescue analgesia when VAS >3. Time of first analgesic request and total rescue analgesic were calculated. Statistical Analysis and Results: based on comparable demographic profiles; time for the requirement of first post-operative rescue analgesia (242.16 ± 23.86 vs. 366.62 ± 24.42) min and total mean rescue analgesic requirement was (104.35 ± 18.96 vs. 76.82 ± 14.28) mg in group R and L respectively. Group R had higher mean VAS score throughout the study period. No side effects found among the groups. These two results were clinically and statistically significant (P < 0.05). Conclusion: Hence, it was evident that intra-articular levobupivacaine give better post-operative pain relief, with an increase in time of first analgesic request and decreased need of total post-operative analgesia compared with ropivacaine.
