[Midazolam used for premedication reinforces sleep induced by flunitrazepam].
This single blind study aimed to discover possible effects of intramuscular premedication with midazolam on the sleep induced by intravenous flunitrazepam. 24 male patients, aged 17 to 71 years, who were to undergo surgery to the distal parts of an upper limb under regional anaesthesia, were randomly assigned to two equal groups: in the midazolam group, an intramuscular premedication of 0.12 mg.kg-1 midazolam with 0.5 mg atropine was given, whereas in the control group atropine only was used. In all patients, 1 mg flunitrazepam was given intravenously 45 min after the premedication, before carrying out regional anaesthesia. No other drug was given. In the midazolam group, the time of loss of spontaneous conversation was reduced (p less than 0.05), as well as the time of eye closure (p less than 0.001), and the time for recovery of the capacity to count backwards was increased (p less than 0.001). So, premedication with 0.12 mg.kg-1 midazolam intravenously 45 min before giving 1 mg flunitrazepam reinforced the sleep induced by the latter.
