Abstract
Individual variation occurs in time to induction of anaesthesia with intravenous drugs. Less free drug is available to cross the blood-brain barrier when the drug is highly protein bound. Since this may prolong time to sleep, we correlated the induction time, serum albumin and total protein concentrations, and doses of midazolam, which is a highly protein bound intravenous anaesthetic. There is a poor correlation (r = 0.062) between induction time and serum protein, a weak (r = 0.524) but statistically significant (p = 0.026) correlation between induction time and serum albumin, and a highly significant (p = 0.003) negative correlation (r = -0.579) between drug dose and induction time. The administration of the appropriate dose of midazolam for induction, therefore, appears to affect induction time more significantly than does the serum albumin concentration. On observe des variations individuelles dans la vitesse d’induction avec les anesthésiques intraveineux. Il y a moins d’agent actif libre disponible pour traverser la barrière hémo-encéphalique dans le cas des anesthésiques à haute affinité (liaison) protéique. Comme cela peut prolonger le temps d’induction, nous avons établi des corrélations entre les vitesses d’induction, les concentrations sériques d’albumine, les protéines totales, et diverses doses de Midazolam, un anesthésique à haute affinité protéique. Nous avons trouvé une mauvaise corrélation (r = 0,063) entre la vitesse d’induction de cet agent et les taux sériques de protéines, une corrélation faible (r = 0,524) mais statistiquement significative (p = 0,026)entre la vitesse d’induction et le taux d’albumine sérique et, enfin, une corrélation négative (r = -0,579) hautement significative (p = 0,003) entre la dose d’agent administrée et la vitesse d’induction. L’administration d’une dose adéquate de Midazolam semble donc influencer la vitesse d’induction plus que la concentration sérique d’albumine.This publication has 15 references indexed in Scilit:
