摘要 目的:观察尼卡地平在动脉导管未闭(PDA)结扎手术中的降压作用。方法:30例病人分为两组(尼卡地平组15例、硝普钠组15例),观察并比较尼卡地平与硝普钠的降压情况。结果:两组降压效果无显著差异,尼卡地平组在阻断PDA停药后血压平稳上升,RPP下降,与硝普钠组比较有显著性差异。尼卡地平最大用量为478μg/kg(21μg*kg-1*min-1),最小用量为46μg/kg(2μg*kg-1*min-1)。结论:尼卡地平降压效果满意,降压作用平稳迅速,停药后血压上升缓慢,无反跳现象,但用药量个体差异较大。 关键词 降压,控制性 尼卡地平 硝普钠 动脉导管未闭
Comparison of effects of hypotension induced with nicardipine and nitroprusside during patent ductus arteriosus ligation operation Zhang Qian,Wang Junke,Sheng Zhuoren,et al.Department of Anesthesiology,First Affiliated Hospital,China Medical University,Shen Yang 110001. Abstract Objective:To observe the effect of hypotension induced with nicardipine in patent ductus arteriosus(PDA) ligation operation.Method:Thirty patients were randomly assigned to two groups.Group Ⅰ with intravenous nicardipine infusion (n=15),group Ⅱ with intravenous sodium nitroprusside infusion (n=15). Result:In group Ⅰ,blood pressure(BP) increased steadily and slowly after the discontinuance of drug when ligation was over,and rate-pressure product (RPP) decreased significantly compared with that in group Ⅱ.The maximal dosage of nicardipine was 478 μg/kg(21 μg.kg.min),minimal dosage was 46 μg/kg(2μg.kg-1.min-1).Conclusion:The hypotension induced with nicardipine is effective,steady and rapid. There is no BP rebounding response to its discontinuance. But the individual required dosage varies greatly. Key words Hypotension,controlled Nicardipine Patent ductus arteriosus Nitrouprusside
在动脉导管未闭(PDA)结扎手术中,控制性降压是确保手术成功的必要手段。目前国内常用硝普钠、硝酸甘油、三磷酸腺苷、前列腺素E1等。近年来已将钙通道阻滞药应用于控制性降压,但对新型的钙通道阻滞药尼卡地平控制性降压尚未见报道。我院采用尼卡地平对PDA结扎手术施行控制性降压,收到满意效果。报告如下:
资料与方法
一、一般资料 PDA结扎手术30例,男13例,女17例。年龄2.5~15岁,其中3岁以下4例,体重10~45kg。ASAⅠ~Ⅱ级,心胸比0.5±0.07,PDA直径6.0±1.53mm。所有病例均未合并其它心血管畸形。 二、麻醉方法 全部采用静吸复合麻醉,术前半小时肌注阿托品0.01mg/kg,哌替啶1mg/kg。麻醉诱导用氯胺酮5mg/kg或2.5%硫喷妥钠5mg/kg、芬太尼3.5~4.0μg/kg,待睫毛反射消失后静注琥珀酰胆碱1.5~2.0m[1] [2] [3] 下一页 上一个医学论文: 己酮可可碱对体外循环中炎症反应的作用 下一个医学论文: 脑干手术中自主呼吸静脉麻醉下脑氧的供需
