Assessment of value of adding low dose of intermediateâ€'acting nondepolarizing muscle relaxant to local anesthesia and hyaluronidase mixture percaruncular and peribulbar anesthesia for high myopes in ophthalmic surgery

Abstract

Objective The purpose of this study was to assess thevalue of adding low-dose intermediate-acting nondepolarizing muscle relaxant to local anesthesia and hyaluronidase mixture percaruncular and peribulbar anesthesia for high myopes in ophthalmic surgery. Patients and methods A total of 82 patients with American Society of Anesthesiologists I–III planned for elective ophthalmic surgery with high myopes enrolled in a double-blind comparative study. The atients were randomized into one of the two groups: group A (n = 42) patients received lidocaine, bupivacaine (local anesthesia), hyaluronidase, and atracurium (intermediate-acting nondepolarizing muscle relaxant) percaruncular and peribulbar. Group B patients received local anesthesia, hyaluronidase percaruncular, and peribulbar. Results As regards demographic data, hemodynamic changes, and oxygen saturation no there was no statistically significant difference between the two groups. About block criteria, the onset of akinesia is shorter in group A than in group B. About duration akinesia, there was no significant difference between the two groups. About analgesia, no significant difference between the two groups. It was noticed that adding atracurium to local anesthesia solution did not significantly increase the risk of complication. Conclusion Thus in the present clinical study, adding atracurium to percaruncular and peribulbar local anesthesia in high myopes undergoing ophthalmic surgery is sufficient and showed excellent safety profile.
