[Predictive value of intradermal tests using muscle-relaxing drugs].
A retrospective postal inquiry was carried out to find out a possible relation between the results of intradermal tests carried out for a previous anaesthetic and the course of a second anaesthetic performed afterwards. This study included 350 patients who have had an intradermal test to vecuronium, alcuronium, suxamethonium, gallamine, pancuronium, thiopentone, fentanyl and droperidol between March 1984 and November 1986. Eighty-nine did not reply (25.4%), 183 (52.3%) did not undergo new general anaesthetic since the skin tests, whilst 78 (22.3%) did. ⋯ No new anaphylactic reaction was observed. Three anaesthetists only were not aware of the results of the intradermal tests at the time of the new anaesthetic. These data tend to demonstrate that a muscle relaxant could be injected in a patient who has had a previous anaphylactic reaction with positive intradermal tests, provided that the drug chosen for the new anaesthetic does not give a positive intradermal reaction.

[Truncal anesthesia of the foot at the level of the ankle: an additional reference mark for the approach to the posterior tibial nerve].
Nerve trunk blocks at the ankle could be a most interesting technique of regional anaesthesia. Unfortunately the posterior tibial nerve is difficult to locate with the usual recommended anatomical landmarks (the tibialis posterior artery). The use of the flexor hallucis longus tendon as an additional landmark has been tested in 71 patients scheduled for surgery on the foot (emergency trauma surgery, amputations, ingrowing toe-nails, removal of bedsores, verrucas). ⋯ Anaesthesia was obtained in 10 +/- 3 min, lasting from 180 to 240 min. There were 88.7% excellent results (n = 63), with 7% fair (n = 5) and 4.2% bad (n = 3) results. Failure concerned 5 cases of tibial nerve block, often due to landmark difficulties (great toe previously amputated, significant ankle oedema, lack of operator experience) and, in 3 cases, forgetting to block a nerve involved.(ABSTRACT TRUNCATED AT 250 WORDS)
