摘要
目的通过对剖宫产术时全身麻醉与硬膜外阻滞的对比研究,探讨两种麻醉方式对胎儿的安全性。方法足月单胎妊娠行择期剖宫产的产妇中,选择血小板计数<50×109 /L的病例行全身麻醉(全麻组),血小板≥50×109 /L者行硬膜外阻滞(硬膜外组),两组各30例。两组产妇均在胎儿娩出时抽取脐动、静脉血,进行血气分析。分别记录两组胎儿娩出时间、手术时间、1分钟和5分钟Apgar评分,并比较这些指标和血气分析指标。结果全麻组和硬膜外组新生儿1分钟Apgar评分分别为(9 5±1 1)、(9 8±0 7 )分, 5分钟Apgar评分均为10分,两组比较,差异均无统计学意义(P>0 05)。胎儿娩出时脐动、静脉血的pH值在全麻组分别为7 31±0 06和7 31±0 04,硬膜外组分别为7 28±0 07和7 32±0 05,两组比较,差异均无统计学意义(P>0 05)。结论全身麻醉和硬膜外阻滞均可安全地用于剖宫产。
Objective To determine the safety of regular doses of general anesthesia and epidural anesthesia on neonates delivered by cesarean sections. Methods Singleton pregnant women for whom elective cesarean sections were planned after 37 gestational weeks were allocated to general anesthesia group (platelet count<50×109/L) or epidural anesthesia group (platelet count≥50×109/L). Arterial and venous samples were withdrawn from the doubly clamped umbilical cord segment at delivery for the pH, bicarbonate, PO_2, and PCO_2. All delivery times, birth weights, and Apgar scores at 1 min, 5 min were recorded. Results The mean Apgar score at 1 min for the general anesthesia group was 9.5±1.1 and ~9.8± 0.7 for the epidural anesthesia group, without significant difference(P>0.05). The Apgar scores at ~5 min of all newborns were 10. The mean umbilical arterial and venous blood pH for the general anesthesia group were 7.31±0.06, 7.31±0.04, and 7.28±0.07, 7.32±0.05 for the epidural anesthesia group respectively. No significant difference was found between the two groups (P>0.05). Conclusions Our prospective study suggests that mode of anesthesia does not influence significantly the outcome of newborn infants delivered by elective cesarean section. It seems that both general and epidural anesthesia can be used in elective term cesarean sections safely.
