[Midazolam used for intramuscular premedication in locoregional anesthesia in urology. Usefulness of late premedication].
Midazolam was used as an intramuscular premedication combined with atropine in a population of 100 patients receiving loco-regional anaesthesia for urologic procedures. Two different dosages were given according to age: 0.10 mg/kg for patients over 50 years, 0.15 mg/kg for those under 50. ⋯ These results confirm that midazolam is a suitable drug for late premedication by the intramuscular route. It is a potent drug with regular short-lasting action, which lead us to suggest its use in ambulatory anaesthesia.

The authors describe a technique of constant flow perfusion of several anaesthetic drugs, using a simple formula to adjust the perfusion rate to the weight of the patients. Calculation of dilutions is easy: the drug concentration is equal to ten times the rate, per hour and per kg, in practical cases. The flow rate is then a tenth of the patient's weight. This method is easy to apply to several drugs, of which pharmacokinetic parameters justify this administration mode: alfentanil, etomidate, vecuronium bromide... but clinical and instrumental observations should be taken into account for the adjustment of the flow.
