Abstract

La présente invention concerne des techniques et des systèmes permettant de déterminer l'emplacement idéal d'un cathéter épidural avant d'administrer une anesthésie. Dans un mode préféré de réalisation, on introduit un liquide aqueux dans un cathéter épidural précédemment introduit dans la colonne vertébrale d'un sujet. On surveille ensuite les réflexes moteurs que le sujet émet en réaction au courant électrique appliqué au moyen de la solution aqueuse. En surveillant la réaction motrice induite par la stimulation électrique, on peut distinguer entre l'emplacement idéal d'un cathéter épidural et l'emplacement du cathéter dans une zone intravasculaire épidurale, rachidienne ou hypodermique. Par ailleurs, dans le mode de réalisation préférentiel, un fil est disposé dans le tube du cathéter pour faciliter le passage du courant électrique. Cependant, pour éviter toute réaction du fil avec la solution aqueuse et/ou le tissu dural du sujet, le fil ne s'étend pas complètement jusqu'à l'extrémité distale du tube du cathéter.
