Combined retro-peribulbar and subconjunctival anesthesia for evisceration surgery

To evaluate the efficacy of retro-peribulbar and subconjunctival anesthesia associated with intravenous sedation in patients undergoing evisceration and orbital implant placement. The charts of 217 patients who underwent evisceration with trans-scleral implant placement were reviewed. Midazolam and fentanyl were used for intravenous sedation. For local anesthesia, a combination of lidocaine with epinephrine and bupivacaine was injected into the retrobulbar, upper peribulbar, and subconjunctival areas. The intraoperative pain and need for supplemental anesthetic injection were recorded prospectively. The surgery was performed with local anesthesia in 116 patients (53%) and with general anesthesia in 101 patients (47%). Patients were significantly older in the local anesthesia group than in the general anesthesia group (mean age, 59.9 years vs 45.2 years; P
