异丙酚和七氟烷对小儿体外循环心肌保护作用的对比研究(1)
参见附件(12kb)。
【摘要】 目的 比较异丙酚和七氟烷对小儿体外循环心的肌保护作用。方法 40例先天性心脏病患儿随机分成2组，每组20例。麻醉诱导后，异丙酚组采用异丙酚麻醉维持，七氟烷组采用七氟烷麻醉维持，所有患儿于麻醉前、体外循环结束后、到达ICU即刻、术后6 h、12 h及24 h抽取静脉血，测定血浆肌钙蛋白I(cTnI)及心肌酶CK-MB。结果 两组患儿术前基础值血浆CK-MB和cTnI浓度差异无统计学意义；与术前基础值相比，两组患儿体外循环结束后、T0、T6、T12及T24显著升高；与异丙酚组相比，七氟烷组体外循环结束后、T0、T6、T12及T24显著降低。结论 七氟烷对小儿体外循环心肌保护作用优于异丙酚。

【Abstract】 Objective To compare the effects ofSevoflurane and Propofolon myocardial preservation during cardiopulmonary bypass(CPB) in pediatric patients.Methods 40 cases pediatric patients with congenital heart disease were randomly divided into two groups with 20 patients each. After induction of anesthesia, Anesthesia was maintained with Propofol in the Propofol group, while Sevoflurane was maintained in the Sevoflurane group. Blood samples were taken before operation,after CPB,ICU arrival(T0),6 h(T6),12 h(T12),24 h(T24) after surgery to determine creatine kinase isoenzyme MB(CK-MB) and cardiac troponin(cTnI) concentrations. Results The concentrations of CK-MB and cTnI at before operation were no differences between two groups. CK-MB and cTnI at after CPB, T0,T6,T12,T24 were significantly increased.While CK-MB and cTnI in the Sevoflurane group were significantly lower than those in the Propofol group at after CPB, T0,T6,T12,T24.Conclusion Sevoflurane is better myocardial preservation than propofol during CPB in pediatric patients.
