Peribulbar anesthesia: efficacy of a single injection with a limited local anesthetic Volume

Abstract

Introduction: Cataract surgery can be performed with peribulbar anesthesia. The classical technique consists of two injections of local anesthetics. The purpose of our Study was to assess peribulbar anesthesia with a single injection and a limited volume of local anesthetics. Material and method: After local ethics committee agreement and oral consent, patients scheduled for cataract surgery using peribulbar anesthesia were prospectively included. The lower temporal puncture was performed with a peribulbar needle with lignocaine sedation. The mixture of local anesthetics was administered with tactile control of orbital pressure. The punch was followed by a 10 min compression of the ocular globe. Akinesia, analgesia, complications, and surgical conditions were noted. Results: A total of 100 patients were included in the Study. Lignocaine was given at a rate of 1.2 mg/kg. The total amount of local anesthetics used was 4.0 ± 0.9 ml. At 15 minutes, ninety patients had akinesia, and 7% had mild chemosis. There were no complications from the puncture. At 5 minutes, 92 percent of patients had akinesia, and at 15 minutes, 94 percent of patients had it. In 94 percent of patients, fixed the eye, and in 94 percent of patients, the vision was central. In 86 percent of cases, the levator muscle motor of the eyelid was blocked. In 7% of patients, moderate chemosis was found. Many of the patients had positive surgical outcomes. Conclusion: Peribulbar anesthesia performed with a single injection and a limited volume of local anesthetics allows cataract surgery in good conditions for the surgeon with excellent analgesia for the patient.
