| Abstract | ||||
| Background: Local anaesthesia relies on studied case comfort, safety, & low complication rates. Nature of proposed surgery, surgeon's preference, & studied case's wishes all influence anaesthetic necessities for ophthalmic surgery, Objectives: aim of this work was to compare lidocaine 2% levobupivacaine 0.5% versus mixture of lidocaine 2% bupivacaine 0.5% as low volume local anesthetic for the eye in posterior segment surgery in peribulbar two injection {supra &infra temporal}. Patients and methods: Patients was divided to 2 groups each of 50 (n=50) randomized with sealed envelope: Group (A) was received lidocaine 2% with bupivacaine 0.5% double injection peribulbar anesthesia. Group (B) was received lidocaine 2% with levobupivacaine 0.5% in double injection peribulbar anesthesia. Results: In group A, block failure was reported in two (4%) patients. In group B, no cases of block failure were reported. Supplementary block was required in two (4%) patients in group A, and in one (two) patient in group B (Figure 2). No statistically important variation was showed among groups regarding block failure or need for supplementary block. Conclusion: Group B had quicker onset, longer duration of action, lower pain scores, & less need for postoperative analgesia. No statistically important variation was observed among groups regarding intraoperative or postoperative problems. | ||||
