脉冲式全自动注药泵在硬膜外分娩镇痛中的应用观察

Application of pulse automatic injection pump in epidural labor analgesia

目的分析脉冲式全自动注药泵在硬膜外阻滞分娩镇痛中的应用效果。方法 选择2016年6月至2017年6月本院收治的自愿行硬膜外分娩镇痛分娩的初产妇98例作为研究对象,采用随机数字表法将其分为两组,各49例。镇痛药物均采用0.08%罗哌卡因联合0.4μg/ml舒芬太尼,参照组采用常规全自动注药泵进行给药,试验组则采用脉冲式全自动注药泵进行给药。比较两组产妇镇痛不同时间的疼痛程度,并统计两组产妇的产程时间,分娩方式,出血量,镇痛药物用量,催产素使用率以及新生儿的阿氏评分(Apgar)等情况。结果 两组镇痛后的VAS评分均显著低于镇痛前,差异均有统计学意义(均P<0.05);试验组产妇在镇痛后1h、3h、5h的VAS评分分别为(2.51±0.45)分、(1.95±0.46)分、(1.70±0.40)分,均低于参照组,差异均有统计学意义(均P<0.05);试验组第一产程时间、总产程时间分别为(435.31±70.21)min、(483.43±79.5)min,均短于参照组,差异均有统计学意义(均P<0.05);试验组产妇镇痛药物总用量、缩宫素使用率分别为(60.5±10.6)ml、20.41%,均低于参照组,差异均有统计学意义(均P<0.05),而两组产妇的出血量、新生儿Apgar评分、剖宫产率比较,差异均无统计学意义(均P>0.05)。结论 在产妇硬膜外阻滞分娩镇痛时采用脉冲式全自动注药泵输注,能发挥更好的镇痛效果,促进产程进展,减少药物用量,值得临床推广。

Objective To analyze the effect of pulse automatic injection pump in epidural block labor analgesia. Methods From June 2016 to June 2017, 98 primiparae who were admitted to our hospital for epidural labor analgesia were selected as study objects. They were divided into an experimental group and a reference group by random digital table method, 49 cases for each group. Both groups were treated with 0.08% ropivacaine 0.4 μg/ml sufentanil. The reference group was administered by conventional automatic injection pump, and the study group by pulse automatic injection pump. The pain degree of analgesia was compared between the two groups at different time. The labor time, delivery mode, bleeding volume, dosage of analgesic drugs, oxytocin utilization rate, and neonatal Apgar score were counted. Results The VAS scores of the two groups were significantly lower after than before analgesia (P < 0.05). The VAS scores 1, 3, and 5 h after analgesia were (2.51±0.45),(1.95±0.46), and (1.70±0.40) in the study group, which were significantly lower than those in the control group (P < 0.05). The time of the first stage of labor and the total duration of labor were (435.31 ±70.21) min and (483.43±79.5) min in the study group, which were significantly shorter than those in the control group (P < 0.05). The total dosage of analgesic drugs and oxytocin utilization rate were (60.5 ±10.6) ml and 20.41% in the study group, which were significantly lower than those in the control group (P < 0.05). There were no statistical differences in the bleeding volume, neonatal Apgar score, and cesarean section rate between the two groups (P > 0.05). Conclusion Pulse automatic infusion pump has a better analgesic effect, and can promote the labor progress and reduce the dosage of drugs, so it is worth being clinically generalized.
