Dose preparatória versus injeção única: estudo comparativo entre diferentes doses de cisatracúrio

Abstract

RESUMO Background and Objectives -The priming technique is an alternative to shorten nondepolarizing neuromuscular blockers onset time. This study aimed at evaluating maximum neuromuscular block onset, tracheal intubation conditions and c a r d i o c i r c u l a t o r y c h a n g e s d e t e r m i n e d b y d i f f e r e n t cisatracurium single or fractional doses.Methods -Participated in this study 80 patients physical status ASA I and II, who were distributed into two groups according to cisatracurium doses: Group I (0.1 mg.kg

Influence of stimulation frequency on rocuronium and pancuronium-induced neuromuscular block onset: acceleromyography evaluation

“…Among hypnotics, propofol is widely used for anesthetic induction because it significantly depresses laryngeal and pharyngeal reflexes and may even do without neuromuscular blockers for tracheal intubation. This effect confirms the superiority of propofol as compared to other hypnotics, expressed by higher incidence of vocal cords immobility, even observed in studies where no blockers were used [29][30][31][32][33][34] . In our study, most patients (97.5%) had satisfactory tracheal intubation conditions and so we may admit that laryngoscopy and intubation maneuvers have not exacerbated reflex autonomic activity to sufficient levels to cause significant blood pressure changes.…”

“…Esse efeito evidencia a superioridade do propofol em relação a outros hipnóticos, exteriorizada pela maior incidência de imobilidade das cordas vocais, vista até mesmo nos ensaios nos quais os bloqueadores não foram utilizados [29][30][31][32][33][34] .…”
