1、第36卷第5期安徽医学2015年5月AnhuiMedicalJournal533苯肾上腺素预注射用于剖宫产术脊麻后低血压的剂量效应王德华杨定东王绍林张骐[摘要]目的探讨苯肾上腺素对剖宫产术脊麻后低血压的合适预注射剂量。方法择期行剖宫产术产妇80例,ASAⅠ或Ⅱ级,随机分成4组(n=20):苯肾上腺素预注射50μg(P1组)、100μg(P2组)、150μg(P3组)和对照组(C组,无预注射),快速输注羟乙基淀粉130/04氯化钠至胎儿取出前(控制总量≤500mL,于L3~4间隙鞘内注入布比卡因9mg+吗啡0.2mg,注药后随即产妇平卧位静脉注射上述不同剂量的苯肾上腺素,胎儿取出前若
2、发生产妇低血压,给予适当(50μg或100μg)苯肾上腺素静脉注射。结果胎儿取出前低血压发生率组间差异无统计学意义(P>005),心动过缓发生率组间差异有统计学意义(P<0.05);所有产妇未发生反应性高血压;随着苯肾上腺素预注射剂量增加,各组产妇胎儿取出前平均最低收缩压(SBP)增加,但差异无统计学意义(P>005),并且随着鞘内苯肾上腺素预注射剂量的增加低血压出现时间延迟且低血压出现的次数及苯肾上腺素总干预剂量逐渐减小,组间差异均有统计学意义(P<005)。术中恶心呕吐发生率,新生儿Apgar评分和脐静脉血气组间差异无统计学意义(P>005)。结论苯肾上腺素预注射100μ
