[Axillary block of the brachial plexus and flunitrazepam premedication in surgery of the upper limb (study of 1,500 cases)].
The authors report their experience of regional block using anaesthesia of the brachial plexus by the axillary approach. 1 500 axillary blocks have been done since 1976. They perfect their technology and report their results. Because of the innocuity of regional block and its simplicity, they use it in seventy per cent of superior limb acute or regular surgery.

Two local anesthetics, Duranest 1% (etidocaine HCl) and Sensorcaine 0.5% (bupivacaine HCl), were tested against each other in dose-related blocks of the fifth ray. This study was conducted under double-blind cross-over conditions using 24 healthy volunteers. It was found that 4 ml. of either agent was sufficient to anesthetize the fifth ray area in all but 4.2% of the injections and 8 ml. of etidocaine always accomplished complete fifth ray anesthesia. ⋯ Residual pain was noted in some of the subjects given etidocaine after complete resolution of sensory anesthesia. Residual pain was not noted in any of the subjects given bupivacaine. Etidocaine was found to have a more rapid onset and a longer duration than bupivacaine or a lidocaine-bupivacaine mixture, and was thus found to be a superior agent in the subjects tested.
