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。 Objective To compare the effects of two different anesthesia methods using muscle relaxant to control respiration and spontaneous respiration in children with bronchoscopy. Methods Forty patients with acute bronchial foreign bodies were randomly divided into two groups. A group to maintain spontaneous breathing group, B group to control the breathing group. Observe and record the anesthesia time, operation time, anesthesia recovery time, easy to set the mirror, intraoperative and anesthesia recovery airway adverse reactions and other indicators. Results The anesthesia time, operation time and anesthesia recovery time in group B were significantly shorter than those in group A, and the complications were easier to set - up. The incidence of airway adverse reactions during operation and anesthesia recovery was lower. Conclusions The use of muscle relaxant to control respiration for the removal of bronchial foreign body in children can maintain a stable depth of anesthesia, safe and effective.
