较小剂量布比卡因一芬太尼腰麻行急诊剖宫产术

目的：探讨较小剂量布比卡因复合芬太尼腰麻行剖宫产术的临床效应。方法：40列行急诊剖宫产术的临产妇，随机双盲分为两组：BF组腰麻用药为布比卡因8mg加芬太尼20ug（n=20）；BS组布比卡因10mg（n=20）。观察两组用药后的MAP、SBP和HR变化、新生儿APgar评分、麻醉效果及不良反应。结果：BS组MAP比BF组下降更加显著，BS组低血压发生率明显高于BF组（P〈0．01）；两组新生儿APgar评分无差异（P〉0．05）；BF组麻醉效果明显优于BS组（P〈0．01）；两组不良反应无明显差异。结论：较小剂量布比卡因复合芬太尼腰麻行急诊剖宫产术，麻醉效果确切，低血压发生率低且不良反应少。

Lower - dose Bupivacaine - fentanyl Spinal Anesthesia for Urgent Cesarean Section

Objective: To study the clinical effectiveness of lower-dose bupivacaine-fentanyl spinal anesthesia for cesarean section.Method: In this randomized,double-blind study,40 parturient women were allocated to one of two groups: group BF,receiving 8mg bupivacaine +20ug fentanyl(n=20) and group BS,10mg bupivacaine(n=20).MAP, SBP,HR,Apgar scores of newborn,anesthetic effects and side effects were observed.Result: The decrease of MAP was greater in group BS compared with that in group BF.The incidence of hypopiesia was higher in group BS compared with that in group BF(p<0.01).There was no significant difference in the Apgar scales of newborns between the two groups(p>0.05). The effect of anesthesia in group BS was significanfly better than that in group BF(p<0.01).There was no significant difference in the side effects between the two groups.Conclusion: There are better effect of anesthesia and lower incidence of hypopiesia and fewer side effects in spinal anesthesia with lower-dose bupivacaine-fentanyl for urgent cesarean section.
