Levobupivacaine Hydrochloric for Painless Labor on Apgar Score and Blood Gas

目的观察低浓度盐酸左布比卡因硬-脊联合麻醉用于无痛分娩对新生儿评分及血气的影响。方法选择120例正常产妇,随机分为两组,每组60例。Ⅰ组为观察组,在宫口开至2～3cm开始行腰麻-硬膜外联合麻醉,腰麻药物为0.75%盐酸左布比卡因1mL+20μg芬太尼1mL,共2mL。Ⅱ组为对照组,按产科常规处理。当胎儿娩出后,取脐动脉血2mL行pH、PCO2和PO2分析,对新生儿进行Apgar评分。结果Ⅰ组麻醉镇痛效果良好,两组新生儿Apgar评分、新生儿脐动脉血血气分析结果比较,差异无统计学意义(P<0.05)。结论低浓度盐酸左布比卡因可安全有效地用于无痛分娩,对新生儿血气和新生儿的评分无影响。

Objective To observe the low concentration of levobupivacaine HCL hardware-spinal anesthesia（ CSEA）for painless labor on Apgar score and blood gas. Methods 120 normal mothers were randomly divided into two groups of 60 cases. I group for the observation group,in the cervix to open to traffic beginning of 2- 3cm of spinal anesthesia-epidural Ma,lumbar anesthetic of 0.75% hydrochloric acid left Bubi card l mL ＋ 20 μg fentanyl 1 mL total of 2 mL. Graup It for the control group conventional treatment according to obstetric. When the baby after delivery, umbilical arterial blood 2 mL line check pH,PCO2 and PO2 analysis, neonatal Apgar score. Results I group of narcotic analgesic effect of a good,two neonatal Apgar score, neonatal umbilical arterial blood gas analysis results,there was no significant ttifference（ P 〈 0.05 ）. Conclusion Low concentrations of Levobupivacaine HCL can be safe and effective for painless childbirth,and neonatal blood of the newborns had no effect on the score.
