Objective To investigate the efficacy and safety of muscle relaxant atracurium in pediatric anesthesia with tracheal foreign body removal. Methods 60 cases with foreign body in children were randomly divided into two groups: without muscle relaxant anesthesia group (A group): intravenous injection of midazolam 0.05～0.1 mg/kg,etomidate 0.2～0.3 mg/kg, fentanyl 1～2μg/kg, spontaneous respiration or mask ventilation; muscle relaxant anesthesia group (B group): A group in the method of anesthesia based on the use of atracurium O. 1～0.3 mg/kg, mask artificial ventilation; bronchoscope into two groups after the high-frequency ventilation were used. Surgery in children with breath holding record cough, SpO2＜90％ of the frequency and recovery time, postoperative nausea and vomiting (PONV), set to mirror the number of times and had set off glottic foreign bodies mirror the degree of difficulty. Resuits Breath-hold technique in the cough, SpO2＜90％ of the frequency and recovery time, PONV, home mirror the number of times over the glottis off foreign bodies in B groups were less than those in the A group (P＜0.05). Conclusion In pediatric foreign body removal surgery, the application of atracurium to eliminate the choking breath-hold technique, can reduce the occurrence of hypoxia, rapid postoperative recovery.%目的 探讨肌松药阿曲库铵用于小儿气管异物取出术的麻醉效果和安全性.方法 60例气管异物患儿,随机分为两组.无肌松麻醉组:静脉注射咪达唑仑0.05～0.1 mg/kg、依托咪酯0.2～0.3 mg/kg、芬太尼1～2 μg/kg,保留自主呼吸或面罩辅助呼吸;肌松麻醉组:在无肌松麻醉组的麻醉方法基础上加用阿曲库铵0.1～0.3 mg/kg,面罩人工通气;两组置入气管镜后均采用高频通气.记录患儿术中屏气呛咳、SPO2<90%的次数和苏醒时间、术后恶心呕吐(PONV)、置镜次数、过声门异物脱落次数及置镜的难易程度.结果 术中屏气呛咳、SPO2<90%的次数和苏醒时间、PONV、置镜次数、过声门异物脱落次数,肌松麻醉组均少于无肌松麻醉组,差异有统计学意义(P＜0.05).结论 小儿气管异物取出术,在咪达唑仑、芬太尼、依托咪酯复合麻醉下,应用阿曲库铵可消除术中呛咳屏气,减少发生缺氧状况,术后苏醒迅速.
