Objective To analyze the application value of remifentanil in fast track cardiac anesthesia in infants and young children. Methods 40 cases of children with congenital heart disease diagnosed as congenital heart disease and were treated with surgery in the hospital, including ventricular septal defect ( VSD ) and atrial septal defect ( ASD ) were selected and divided into the experimental group and the control group according to the random number table method, 20 cases in each group. The hemodynamic parameters of patients at different time after operation were recorded, and the time of extubation and the use time of ventilator were recorded. Results There was no significant difference in the hemodynamic parameters at different time between the experimental group and the control group ( P ﹥ 0. 05 ) , but the extubation time and the use time of the ventilator in the experimental group were significantly shorter than that of the control group( P ﹤ 0. 05). Conclusions Remifentanil for intraoperative hemodynamic stability has obvious efficacy, can reduce the stress re-action of patients, shorten the extubation time, and make the fast channel anesthesia in pediatric cardiac surgery of good application value.%目的：探讨婴幼儿快通道心脏麻醉中瑞芬太尼的应用价值。方法选择医院住院诊断为先天性心脏病并拟行手术治疗的患儿40例，包括室间隔缺损（VSD）及房间隔缺损（ASD），依据随机数字表法将40例患儿随机分成试验组及对照组，各20例。分别观察并记录术后患儿不同时间点血流动力学指标、术后拔管时间及呼吸机使用时间。结果试验组患儿不同时间点血流动力学指标与对照组比较差异无统计学意义（ P ﹥0.05），但试验组患儿术后拔管时间及呼吸机使用时间均较对照组明显缩短，且差异具有统计学意义（ P ﹤0.05）。结论瑞芬太尼对稳定术中血流动力学效果明显，可减轻患者的应激反应，缩短拔管时间，在小儿心脏手术快通道麻醉中有良好的临床应用价值。
