【摘要】 目的:探讨全麻经口腔气管插管时可变头位对声门显露质量的影响。方法:180例全麻插管病人(ASAⅠ~Ⅱ)诱导(咪达唑仑0.2 mg.kg-1,芬太尼0.004 mg.kg-1,维库溴铵0.1 mg.kg-1),成功后分别在头简单过伸位下和可变头位下用macintosh喉镜显露声门,记录Cormack and Lehane评分。结果:Cormack and Lehane评分Ⅰ、Ⅱ级头简单过伸位下所占比例为86.1%,可变头位下所占比例为98.9%,两者比较差异有显著性(P<0.05)。结论:可变头位能显著提高声门的显露质量。更多还原

【Abstract】 Objective: To investigate the effect of changeable head position on glottis exposure and its use during general anesthesia by orotreacheal intubation.Methods: 180 patients for general anesthesia were induced with midazolam 0.2mg/kg,fentanyl 0.004mg/kg and vecuronium 0.1mg/kg,and then the glottises were exposed with macintosh laryngoscopy under simple head extension and changeable head position respectively by a skilled anesthetist,recording the Cormack and Lehane grade.Results: The ratio of Cormack and Lehane scope Ⅰ、Ⅱwas 86.1% under simple head extension,and 98.9% under the changeable head position(P<0.05).Conclusion: Changeable head position can improve the glottis visualization under direct laryngoscopy in a great degree.更多还原
