Abstract
A study was conducted to determine the optimal interval between the administration of d-tubocurarine (dTc) and succinylcholine (SCh) with regard to onset and duration of neuromuscular block and presence of fasciculations and postoperative myalgias. Forty female patients received dTc 3 mg .70kg-1 prior to SCh 1.5mg.kg-1. The interval between drugs was 0, I, 3, 5, or 7 minutes Transduced thumb adduction recorded block onset and recovery. Fasciculations were visually detected. Myalgias were assessed on postoperative interview. Pretreatment interval did not affect the onset or recovery of neuromuscuiar block. Postoperative myalgias were also independent of pretreatment timing. Fasciculations were blocked with 3, 5, or 7 minute intervals, but not with Oor I minute intervals. Therefore, three minutes appear to be the optimal, time interval between administration of dTc and SCh since shorter intervals do not inhibit fasciculations and longer intervals do not afford any additional advantages. On a cherché à déterminer I’mtervalle idéal à maintenir entre l’administration préventive de la d-lubocurarine (dTc) et celle de la succinytcholine (SCh), intervalle qui permettruit de conserver la rapidité d’ installation du bloc neuromusculaire et sa durée tout en minimisanl ies fasciculations et Ies myalgies post-opératoires. L étude a porté sur 40 patientes ayant reçu 3 mg 70 kg-1 de dTc avant I’administration de 1.5 mg-kg-1 SCh. Les patientes ont été réparties en groupes ou l’intervalle entre I’administration des médicaments a été de O, 1, 3, 5, et 7 minutes. La mesure de l’adduction du pouce par transducteur moniwrait I installation et la disparition du bloc neuromusculaire. Les fasciculations etaient observées visuellement et les myalgies évaluées au cours d’une entrevue post-opératoire. L’installation ou la disparition du bloc neuromusculaire n’est pas influencée par I’intervalle entre les injections non plus que les myalgies post-operatoires. Les fasciculations étaient éliminées pour des intervalles de 3, 5 ou 7 minutes maix encore présentes pour des intervcdles de 0 ou I minute. Il semble done qu’un intervalle de trot’s minutes entre I administration de dTc et de SCh est souhaitable car des intervalles plus courts ne préviennent pas les fasciculations et des intervalles plus longs n’opponent aucun avantage additionnel.This publication has 24 references indexed in Scilit:
