DOUBLE-BLIND STUDY OF THE REVERSAL OF MIDAZOLAM-SUPPLEMENTED GENERAL ANAESTHESIA WITH RO 15-1788

The actions and side effects of the benzodiaze-pine antagonistRo 15–1788 were evaluated in a randomized double-blindclinical study in which midazolam was used as an anaestheticagent. Sixty women who underwent laparoscopy were treated withRo 15–1788 or with placebo after the surgical procedure.Ro 15–1788 reversed the hypnotic effect of midazolam withina few minutes. The patients were alert, co-operative, orientedand had good recall of events after awakening. The effects werestatistically better than placebo for up to 30 min after administration.Arterial pressure and heart rate remained stable and there wereno significant side effects. The availability of Ro 15–1788allows effective reversal of midazolam when this is used duringgeneral anaesthesia.
