Anterograde amnesia as a possible postoperative complication of Midazolam as an agent for intravenous conscious sedation.
Anterograde amnesia is often considered to be a beneficial effect of intravenous conscious sedation. The recently introduced benzodiazepine, midazolam, has associated with its administration a significant anterograde amnesic period. In the case presented here, a healthy young female presented for third molar extraction under midazolam conscious sedation and local anesthesia. After uncomplicated removal of the teeth and clinically adequate recovery from sedation, it was noted that the patient had swallowed the postsurgical gauze packs. Efforts at recovery of the gauze packs were futile. Follow-up discussion with the patient revealed a complete lack of recall of all events occurring for up to an hour or more after the administration of intravenous midazolam. The need for written and oral postoperative instructions to both the patient and his/her escort is emphasized.
