Abstract
One hundred and sixty patients, divided randomly into four groups received normal saline (5 ml), d-tubocurarine (0.05 mg· kg-1), diazepam (0.1 mg·kg-1) or lidocaine (1 mg·kg-1) as pretreatment, in a double blind manner, five minutes before anaesthetic induction with thiopentone and succinylcholine (1 mg·kg-1). Succinylcholine caused a significant increase in IOP in all groups. However, in the lidocaine group, this increase was significantly less than that observed in the control group. The post-succinylcholine increase in IOP was further aggravated by tracheal intubation in all except the lidocaine group. A further clinical trial with higher doses of lidocaine is suggested to assess its ability to obtund the succinylcholine-induced increase in IOP. Lidocaine in a dose of 1 mg·kg-1 IV prevents the rise in IOP which follows intubation. Cent soixante patients divisés ďune façon randomisée en quatre groupes ont reçu du salin physiologique (5 ml), de la d-tubocurarine (0.05 mg·kg-1), du diazepam (0.1 mg·kg-1) ou de la lidocaine (1 mg·kg-1) comme pré-traitment à double insu, cinq minutes avant ľinduction de ľanesthésie avec du thiopentone et de la succinylcholine (1 mg·kg-1). La succinylcholine a provoqué une augmentation significative de la pression intraoculaire chez tous les groupes. Cependant, pour le groupe lidocaine, cette augmentation était significativement moindre que celle observée chez le groupe contrôle. Ľaugmentation de la pression intraoculaire post succinylcholine était davantage aggravée par ľintubation trachéale chez tous les groupes à ľexception du groupe lidocaine. Un essai clinique ultérieur avec de plus fortes doses de lidocaine est suggéré afin ďévaluer sa capacité de diminuer ľaugmentation de la pression intraoculaire induite par la succinylcholine malgré qu’elle est suffisante aux doses de 1 mg·kg-1 pour prévenir ľaugmentation de la pression intra-oculaire après ľintubation.This publication has 25 references indexed in Scilit:
