Abstract：
PURPOSE:To assess the efficacy of sublingual lorazepam in inducing amnesia when used as a premedication for peribulbar anesthesia. SETTING:Department of Ophthalmology in a large district general hospital. METHODS:Following local ethical committee approval, a prospective, randomized, placebo-controlled, double-blind study of patients having routine cataract or glaucoma surgery under local anesthetic was undertaken. Patients older than 90 years of age or who were frail, confused, or unfit for surgery were excluded, as were those who weighed less than 50 kg, swallowed the tablet, or had missing data. Sixty volunteer patients were randomly given 1 mg of lorazepam or a placebo tablet by sublingual route 1 hour preoperatively. All patients were assessed for sedation, akinesia, intraoperative analgesia, and patient response including amnesia. RESULTS:There was no significant difference between groups in sedation, analgesia, or akinesia. Overall patient response was better in the lorazepam group (P = .05). Patient-reported incidence of amnesia was significantly higher in the lorazepam than in the placebo group (P < .05). CONCLUSIONS:Sublingual lorazepam improved patient comfort by inducing amnesia, and in the low dose used in this study, did not adversely affect surgery by undue heavy sedation.
