摘要: 目的

探讨程控硬膜外间歇脉冲注入(PIEB)模式用于分娩镇痛的效果,以及对脐血流及脐动脉血气的影响,为临床寻找更为理想的硬膜外分娩镇痛给药模式提供依据。

方法

选择要求行分娩镇痛的足月单胎初产妇90例陆续入组观察,采用随机数字表法将研究对象产妇随机分为PIEB组和持续性硬膜外输注(CEI)组,每组45例。2组产妇均给予首次剂量(0.08 g·L-1罗哌卡因+0.4 mg·L-1右美托咪定)10 mL。PIEB组产妇注入首次剂量后1 h连接PIEB镇痛泵,脉冲剂量8 mL·h-1,速度7 mL·min-1。CEI组产妇注入首次剂量后立即连接CEI镇痛泵,持续背景剂量8 mL·h-1。比较2组产妇镇痛前(T0)、镇痛后30 min(T1)、镇痛后1 h(T2)、镇痛后2 h(T3)和宫口开全时(T4)的视觉模拟评分(VAS)。比较2组T0~T3的胎儿脐动脉波动指数(PI)、脐动脉阻力指数(RI)和脐动脉血流速度收缩峰值与舒张峰值比值(S/D);比较2组胎儿娩出即刻的脐动脉血气pH值、剩余碱(BE)值和新生儿Apgar评分;比较2组产妇第一产程时间、第二产程时间、满意度和不良反应。

结果

2组产妇在T0、T1、T2和T3的VAS评分比较差异无统计学意义(P>0.05);PIEB组T4时间点的VAS评分低于CEI组(P<0.05)。2组在不同时间点的胎儿PI、RI和S/D比值比较差异无统计学意义(P>0.05);2组产妇胎儿脐动脉血气pH值和BE值比较差异均无统计学意义(P>0.05);2组新生儿Apgar评分比较差异无统计学意义(P>0.05);2组产妇第一产程时间、第二产程时间和不良反应发生率比较差异均无统计学意义(P>0.05);PIEB组产妇镇痛满意度得分明显高于CEI组(P<0.05)。

结论

PIEB模式用于分娩镇痛对脐血流及脐动脉血气无明显影响,安全性好。

Abstract: Objective

To explore the effect of programmed intermittent epidural bolus(PIEB) mode for labor analgesia and its influence in the umbilical blood flow and umbilical artery blood gas, and to provide the basis for finding a more ideal mode of epidural labor analgesia.

Methods

Ninety cases of full-term singleton neonates who required labor analgesia were randomly divided into PIEB group and continuous epidural infusion (CEI) group by random number table method,with 45 cases in each group.The maternity patients in two groups were given the first dose (0.08 g·L-1 ropivacaine+0.4 mg·L-1 dexmedetomidine) 10 mL.The maternity patients in PIEB group were connected to the PIEB analgesia pump 1 h after the injection of the first dose, with the pulse dose of 8 mL·h-1 and the speed of 7 mL·min-1;the patients in CEI group were connected to the CEI analgesia pump immediately after the first dose injection, and the continuous background dose was 8 mL·h-1.The VAS pain scores of the maternity patients in two groups before analgesia (T0), 30 min after analgesia (T1),1 h after analgesia (T2), 2 h after analgesia (T3) and full-time uterine opening (T4) were compared. The umbilical artery pulsatitly index (PI), umbilical artery resistance index (RI) and the ratios of systolic peak to diastolic peak (S/D) of fetal umbilical artery blood flow velocity of the patients at T0-T3 were compared. The umbilical artery blood gas pH values, residual alkali (BE) values and the newborn Apgar scores immediately after delivery of the maternity patients in two group were compared.The first stage of labor, the second stage of labor, satisfaction and adverse reactions were compared between two groups.

Results

There were no differences in the VAS scores of the patients at T0, T1, T2 and T3 between two groups (P>0.05).The VAS score of the maternity patients in PIEB group at the T4 time point was lower than that in CEI group (P<0.05). There were no differences in the fetal PI, RI, and S/D ratios of the maternity patients at different time points between two groups (P>0.05).There were no statistically significant differences in the umbilical artery blood gas pH values and BE values of the maternity patients between two groups(P>0.05), and there was no significant difference in the Apgar score between two groups (P>0.05). There were no significant differences in the first stage of labor, the second stage of labor and the adverse reactions between two groups(P>0.05). The score of satisfaction with analgesia of the maternity patients in PIEB group was significantly higher than that in CEI group(P<0.05).

Conclusion

PIEB mode for labor analgesia has no significant effect on the umbilical blood flow and umbilical artery blood gas, and has better safety.
