不保留自主呼吸全麻用于小儿支气管异物取出术的临床观察

目的对比研究使用肌松剂控制呼吸与保留自主呼吸两种不同麻醉方法用于小儿支气管镜取异物术的效果。方法 40例急诊行支气管异物取出术患儿,随机分为两组。A组为保留自主呼吸组,B组为控制呼吸组。观察并记录麻醉时间、手术时间、麻醉苏醒时间、置镜容易程度、术中及麻醉恢复期气道不良反应发生情况等指标。结果 B组麻醉时间、手术时间、麻醉苏醒时间均明显短于A组,且置镜更容易,术中及麻醉恢复期气道不良反应发生率更低。结论使用肌松剂控制呼吸用于小儿支气管异物取出术能维持稳定的麻醉深度,安全有效。

Clinical observation of general anesthesia without spontaneous breathing for pediatric bronchial foreign body extraction

Objective To compare the analgesia effect of two different anesthetic techniques which controlled breathing with muscle relaxants and maintained spontaneous breathing for bronchial foreign body removal in children.MethodsForty pediatric patients performed emergency bronchial foreign body removal were randomized to two groups： Group A with spontaneous breathing and Group B controlled breathing.Outcomes including the time of anesthesia,the time of operation,the time of recovery,the difficult grade of setting bronchial mirror and perioperative or postoperative breath airway adverse events,were observed.Results The time of anesthesia, operation and recovery of Group B all were significantly shorter than the Group A, and set bronchial mirror more easily, and the incidenee of breath tract adverse reactions lower during operation and recovery. Conclusion The method of controlled breathing used muscle relaxant for pediatric bronchial foreign body extraction is safe and effective. It can maintain enough stable depth of anesthesia.
