七氟醚在小儿支气管异物术中的应用

Application of Sevoflurane on bronchial foreign body surgery

目的观察七氟醚在小儿支气管异物术中的麻醉效果。方法 50例支气管异物患儿随机分为观察组和对照组各25例。观察组采取七氟醚吸入麻醉;对照组采用静脉注射芬太尼复合丙泊酚麻醉。观察诱导期患儿表现,记录患儿睫毛反射消失时间、苏醒时间,监测并记录诱导前、置入支气管镜后5min的心率、SPO2和呼吸频率。结果观察组躯体运动、屏气呛咳、喉痉挛、分泌物增多发生率均低于对照组,差异有统计学意义(P<0.05)。观察组睫毛反射消失时间、苏醒时间短于对照组,差异均有统计学意义(P<0.05)。置管5min时观察组心率、呼吸频率均高于诱导前,且观察组低于对照组,差异均有统计学意义(P<0.05)。结论七氟醚在小儿支气管异物术中的应用效果显著。

Objective To investigate the effect of Sevoflurane on bronchial foreign body surgery. Methods 50 chil- dren with bronchial foreign bodies were randomly divided into observation group and control group （25 patients in each）. The observation group received Sevoflurane anesthesia; the control group received intravenous fentanyl and propofol anesthesia. Per- formance during induction period was observed. Reflex time of loss of eyelash, recovery time were recorded. Heart rate, SPO2, and respiratory rate pre - induction and 5 min after bronchoscopy were compared. Results The incidence rates of body move- ment, breath cough, laryngospasm, increased secretions were lower than those in the control group, and the differences were sta- tistically significant （ P 〈 0.05 ）. Eyelash reflex time and recovery time in observation group were shorter than those in the con- trol group （P 〈 0.05）. 5min after placing catheter, the heart rate, respiratory rate in both groups were increased, were lower than that before induction（ P 〈 0.05 ）, and there were significant differences between the two groups（ P 〈 0.05 ）. Conclusion Sevotlurane in treatment of bronchial foreign body surgery is effect.
