Abstract :

<p>&nbsp;Aim:The objective of this study was to compare the rapidity of onset and efficiency of peribulbar block produced with 0.75% Ropivacaine alone with the traditional mixture of 0.5% Bupivacaine and 2% Lidocaine for cataract Surgery. Methods: A total number of 60 patients scheduled for cataract surgery with peribulbar anesthesia were randomly allocated into two groups of 30 patients each, who receive mixture of 0.5% 2 ml + Lidocaine 2% 3 ml (Group I) or 0.75% Ropivacaine 5 ml (Group II). Hyaluronidase was added to both the groups. Ocular and eyelid movement scores were evaluated at 2,4,6,8 minutes after injection. Intraoperative analgesia was evaluated by verbal pain scores, need for supplementary anesthesia, hemodynamic parameters and incidence of perioperative complications were recorded. Results: The ocular movement scores at 2,4,6 and 8 min was significantly lower in Group I than in Group II, however there was no significant difference between both the groups at 8 min. Duration of surgery and hemodynamic parameters did not differ among the groups. Conclution: 0.75% Ropivacaine alone is an effective alternative to 0.5% Bupivacaine and 2% Lidocaine for peribulbar anesthesia. Although the traditional mixture of Bupivacaine and Lidocaine resulted in significantly lower ocular movement scores at 2,4 and 6 minutes ;at 8 minute both anesthetic solutions provide similar anesthetic conditions to perform cataract surgeries.</p>
