摘要
目的 观察硝普钠 (SNP)复合拉贝洛尔 (La)在硬膜外阻滞麻醉或全麻时的控制性降压效应。方法 5 0例ASAⅠ～Ⅱ级手术患者 ,根据麻醉方法的不同分为两组 ,组Ⅰ 2 6例均为全髋置换术患者在硬膜外阻滞加控制性降压麻醉下手术 ;组Ⅱ 2 4例则在全麻加控制性降压麻醉下手术。麻醉平稳后 ,两组均静注 0 .0 5～ 0 .2mg/kgLa ,5min后以SNP维持平均动脉压在 7.3～ 8.7kPa间。结果和结论 小剂量La复合SNP控制性降压可减少两者用量 ,易维持低血压状态。无反射性心动过速。复压过程平稳 ,无反跳性高血压。硬膜外阻滞麻醉和全麻相比 。
objective To compare the deliberated hypotensive effects of sodium nitroprusside(SNP) with labetalol(La)in general or epidural anesthesia.Methods Fifty patients were divided into two groups according to different anesthetic methods.In group l(n=26) deliberated hypotension was induced by 0.05～0.1mg/kg La and SNP during epidural block.In group Ⅱdeliberated hypotension was induced by 0.1～0.2mg/kg La and SNP during general anesthesia.Results and Conclusion U sing SNP with La induces can adjust hypotension easily without compensatory tachycardia and rebound hypotension.The epidural anesthesia can decrease the dose of SNP and La and enforce the hypotensive action of SNP with La and reduce the incidence of its complication.
