The role of midazolam and flumazenil in urology.
The effects of midazolam (3-10 mg i.m.) and their reversal by flumazenil were studied in transurethral endoscopic procedures performed using topical analgesia. In one randomised study, patients (n = 84) received either no medication or flumazenil (0.5 mg i.v.) on completion of endoscopy. Recovery was assessed subjectively. Within 15 min, 83% of those receiving flumazenil were considered ready for discharge compared with only 24% of the control group (P less than 0.001). In a second randomised, double-blind, placebo-controlled trial of 44 patients, post-operative recovery was assessed using five objective psychomotor tests. Whereas the placebo group took up to 2 h to recover, those receiving flumazenil recovered fully or returned to near control values within 15 min. Sedoanalgesia--a technique combining adequate local anaesthesia with sedation (using midazolam)--has wide application in urology, and the introduction of flumazenil has major implications for the practice of day-case surgery.
