目的：盐酸罗哌卡因和舒芬太尼蛛网膜下腔麻醉应用在剖宫产中常有报道，本文旨在探讨低剂量盐酸罗哌卡因复合低剂量舒芬太尼腰硬联合麻醉在剖宫产中应用的临床效果。方法选择我院接受腰硬联合麻醉剖宫产手术的初产妇的60例，随机分为罗哌卡因组（R组）和布比卡因组（B组），分别给予罗哌卡因10mg或布比卡因6.6mg，复合3.3ug的舒芬太尼。比较两组的感觉运动神经阻滞，血流动力学以及新生儿结果。结果2组产妇生命体征，血流动力学，新生儿Apgar评分、差异无统计学意义；与B组相比，R组几乎无运动阻滞，手术时间更长，产妇满意度更高。结论低剂量盐酸罗哌卡因复合舒芬太尼腰硬联合阻滞用于剖宫产无运动阻滞，安全有效。“,”Objective:Ropivacaine have been studied for intR21thecal use during cesarean section in combination with sufentanil. The purpose of the present study was to research ropivacaine and sufentanil in low doses and in cesarean section.Methods:During the study of combined spinal-epiduR21l anesthesia, 60 Cesarean section patients were R21ndomly assigned to receive a spinal injection of either 10mg ropivacaine or 6.6mg bupivacaine both combined with sufentanil 3.3μg. The two local anesthetics were compared with respect to sensory and motor block,the severity of hypotension and neonatal outcome.Result:More patients in bupivacaine had a Bromage-3 motor block at incision. the interval between the spinal injection and the end of surgery is longer in the ropivacaine group. Hemodynamic values were compaR21ble,there is no difference between the study groups in systolic blood pressures and the incidence of severe hypotension,Apgar scores did not differ. Conclusion:When performing a low-dose combined spinal-epiduR21l anesthesia for cesarean section, ropavacaine and sufentanil can be used safely and successfully.
