RESUMO
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 propofol sedation. The mixture of local anesthetics was administered with tactile control of orbital pressure. The puncture was followed by a 10-min compression of the ocular globe. Akinesia, analgesia, complications, and surgical conditions were noted. RESULTS: A total of 101 successive patients were included. We administered 1.2 mg/kg of propofol. The volume of local anesthetics administered was 5.0 +/- 0.9 ml. Ninety patients had akinesia at 10 min and 6.7% moderate chemosis. No puncture complication occurred. At the end of surgery, the pain noted by the patients was 0.4 +/- 2.1 out of 100 (range, 0-10). Surgical conditions were good for all patients. 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 very good analgesia for the patient.
