目的观察连续性硬膜外麻醉与蛛网膜下腔麻醉对剖宫产新生儿pH值的影响。方法 32例产妇随机分为二组:连续性硬膜外麻醉组(A)和蛛网膜下腔麻醉(B),每组成16例。两组麻醉前均开放静脉,输入乳酸钠林格氏液或胶体300~50ml。术中产妇血压下降>20%基础血压值,给予盐酸麻黄碱5~10mg,观察两组胎儿取出后脐动脉血气(pH)值。结果两种麻醉方式均能安全满足剖宫产手术的需要,术中适当有效扩容,维持生命体征平稳,对新生儿酸碱度(pH)无不良影响。
Objective To observe the effects of continuous epidural anesthesia and subarachnoid anesthesia on the pH value of neonates with cesarean section. Methods 32 pregnant women were randomly divided into two groups: continuous epidural anesthesia group (A) and subarachnoid anesthesia (B), each consisting of 16 cases. Both groups were opened before anesthesia, intravenous infusion of sodium lactate Ringer’s solution or colloid 300 ~ 50ml. Intraoperative maternal blood pressure decreased> 20% of the baseline blood pressure, given ephedrine hydrochloride 5 ~ 10mg, observed two groups of fetal umbilical artery blood gas (pH) value. Results Both anesthesia methods could safely meet the needs of cesarean section operation. Appropriate and effective dilatation during operation was used to maintain stable vital signs and had no adverse effect on neonatal pH.
