Abstract
As a result of experience at the Montreal General Hospital, it has been found that intravenous guanethidine blockade of extremities has therapeutic, prophylactic and diagnostic value in conditions where the aetiology is a disorder of sympathetic nervous conduction. The properties of guanethidine, namely its selective action on blocking the sympathetic nervous system peripherally, together with its long half time and rapid tissue fixation, render it a very useful drug in techniques where an isolated limb is blocked with guanethidine. Experience on an 18-month basis suggests that the procedure of intravenous guanethidine blockade offers exceptionally good results for a non-invasive technique. Work is now in progress to study the possible use of guanethidine in the treatment of phantom limb pain, and also to see whether other drugs, such as thymoxamine, could be used in a similar fashion to guanethidine. Les auteurs revoient la pharmacologic de la guanethidine et discutent de son usage intraveineux pour la production de blocs sympathiques au niveau des membres supérieurs et inférieurs. Une manchette double est utilisée pour isoler le membre avant ľinjection intraveineuse et reste gonflée 15 minutes après ľinjection pour permettre la fixation de ľagent. Les auteurs considèrent que cet agent peut être utilisé pour la production de blocs sympathiques à des fins thérapeutiques, prognostiques ou diagnostiques. Cette technique est sécuritaire, simple et efficace si elle est effectuée telle que décrite.This publication has 7 references indexed in Scilit:
