✦ Synopsis
Sixty five patients with various traumatic lesions of the fingers have been operated on under digital anaesthesia using 3 ml of 2% Mepivacaine injected into the flexor tendon sheath. The anaesthesia was adequate for surgery in all instances except in one patient. No complications were encountered with this technique. The authors studied the mechanism of action by dissecting a cadaveric hand after injecting a tracer (Methylene blue) in place of the local anaesthesia, suggesting, but not proving, that anaesthesia is achieved by blocking the nerve in the area of the injection.
R6sum6. Soixante-cinq patients, victimes de traumatismes divers des doigts, ont dtd op~r& sous anesth~sie locale, a travers la gatne du tendon fl6chisseur, par 3ml de
Mapivaca~'ne a 2%. Sauf dans un cas, l'anesthdsie a toujours permis d'effectuer l'intervention. II n 'y a pas eu de complications dues cette technique. Les auteurs ont 6tudid le m~canisme d'action en dissiquant la main d'un cadavre auquel avait dtd, au pr6alable, administr6 un marqueur (bleu de mdthylbne) comme s 'il s ' agissait d' un anesth&ique local On a pu en conclure que l'anesth6sie dtait obtenue par le blocage du nerf prbs du lieu d'injection.
