小儿七氟醚麻醉诱导方法的比较

Comparison of different induction methods of sevoflurane inhalation in children

目的观察七氟醚诱导方法在小儿腹腔镜短小手术中的应用效果。方法将择期行腹腔镜腹股沟斜疝结扎术3～6岁患儿60例,随机均分为面罩肺活量吸入法诱导组(A组)与面罩潮气量吸入法诱导组(B组)。记录睫毛反射消失时间、气管插管时间、血流动力学指标、拔管时间、意识恢复时间及不良反应。结果 A组睫毛反射消失时间(43.5±4.4)s,明显短于B组的(68.8±7.6)s(P<0.01);A组气管插管时间(3.5±0.7)min,明显短于B组的(6.7±1.4)min(P<0.01);两组拔管时间、意识恢复时间、不良反应的发生率差异无统计学意义。结论两种七氟醚吸入诱导方法均可获得良好的气管插管条件;面罩肺活量吸入诱导法起效更为迅速。

Objective To compare the different induction methods of sevoflurane inhalation in children. Methods Sixty patients aged 3-6 years old undergoing elective laparoscope herniorraphy were randomly and equally divided into anesthesia induction with vital capacity group （group A） and with tidal volume group （group B）.The time to lash reflex lost,tracheal intubation,extubation,consciousness recovery,hemodynamic variables and adverse events were recorded. Results The time to lash reflex lost in group A was shorter than that in group B[（43.5±4.4） s vs.（68.8±7.6） s,（P〈0.01）.So did the time for tracheal intubation [（3.5±0.7）min vs.（6.7±1.4） min,（P〈0.01）].There were no significant differences in the times of extubation,consciousness recovery,and adverse events between two groups. Conclusion The two induction methods of sevoflurane inhalation can provide excellent condition of intubation in children,of which the onset time of anesthesia induction with vital capacity is shorter than that with tidal volume technique.
