| 摘 要： | 目的探讨脑电双频指数(BIS)指导下调节七氟烷体积分数能否有效抑制行斜视手术时患儿的眼心反射。方法 52例行手术治疗的先天性斜视患儿被随机分为A、B两组,分别维持BIS值为40(A组)和60(B组)左右,两组均采用吸入七氟烷行全身麻醉,术中监测脉搏血氧饱和度(SpO2)、血压(BP)、心电图(ECG)、呼吸末二氧化碳分压(petCO2),记录眼心反射的发生率及呼气末七氟烷体积分数。结果 A组的眼心反射发生率为11.6%(3/26),显著低于B组的34.9%(9/26,P<0.05)。A组的呼气末七氟烷体积分数为0.021±0.003,显著高于B组的0.015±0.005(P<0.05)。结论先天性斜视患儿行手术治疗,吸入七氟烷行全身麻醉时,BIS值维持于40±1时其眼心反射的发生率低于BIS值为60±2时。

| Abstract: | Objective To investigate whether bispectrial index(BIS)-guided sevoflurane concentration change can effectively suppress the oculocardiac reflex in pediatric patients receiving strabotomy.Methods Totally 52 congenital esotropia children were randomly divided into group A and B(each n=26).All children were anesthetized with sevoflurane inhalation.The BIS was maintained at about 40 in group A and about 60 in group B.The following indicators,including pulse oxyhemoglobin saturation(SpO2),blood pressure(BP),ele... |
