目的 探究程控硬膜外间歇脉冲注入(PIEB)技术与硬膜外持续输注(CEI)技术对分娩镇痛的影响。方法 选取本院200例ASA Ⅰ～Ⅱ级的正常妊娠产妇作为研究对象，按照随机数字表法分为两组，各100例。对照组应用CEI技术进行镇痛分娩，治疗组应用PIEB技术进行镇痛分娩。比较两组镇痛前、镇痛后0。5 h、镇痛后1h、镇痛后2h、宫口全开时及产后1 h的视觉模拟评分法(VAS)评分;比较两组产程指标情况、分娩方式、产妇满意度情况、分娩结局以及不良反应发生情况。结果 与镇痛前相比，两组镇痛后各时段的VAS评分较镇痛前明显下降，且治疗组优于对照组，差异有统计学意义(P＜0。05)。治疗组给药总量、病人自控镇痛追加次数、产后出血量、不良反应总发生率均低于对照组，自然分娩率、产妇满意度评分均高于对照组，差异有统计学意义(P＜0。05)。两组在各个产程时间、剖宫产率、新生儿1 min Apgar评分、新生儿5 min Apgar评分上比较差异无统计学意义(P＞0。05)。结论 使用PIEB技术进行分娩镇痛，可获得安全、有效的止痛效果，能明显降低麻醉药物用量，极大地提升产妇的满意度，并且不会影响分娩结果，值得推广。
Study on the role of programmable epidural intermittent pulse injection technology in analgesic delivery
Objective To explore the effects of programmed epidural intermittent pulse injection(PIEB)and continuous epidural infusion(CEI)techniques on labor analgesia.Methods 200 normal pregnant and postpartum women with ASAⅠ-Ⅱlevel in our hospital were selected as the research subjects and divided into two groups using a random number table method,with 100 cases in each group.The control group received CEI technology for pain relief,while the treatment group received PIEB technology for pain relief during delivery.Compare the VAS scores of two groups before analgesia,0.5 h,1 h,2 h after analgesia,at full opening of the cervix,and 1 h postpartum;Compare the delivery process indicators,delivery methods,maternal satisfaction,delivery outcomes,and incidence of adverse reactions between two groups.Results Compared with before analgesia,the VAS scores of the two groups at each stage after analgesia decreased significantly,and the treatment group was better than the control group,with a statistically significant difference(P＜0.05).The total amount of medication administered,the number of additional patient-controlled analgesia,postpartum hemorrhage,and the incidence of adverse reactions in the treatment group were all lower than those in the control group.The natural delivery rate and maternal satisfaction score were higher in the treatment group than in the control group,and the differences were statistically significant(P＜0.05).There was no statistically significant dififerencebetween the two groups in terms of labor duration,cesarean section rate,newborn 1-minute Apgar score,and newborn 5-minute Apgar score(P＞0.05).Conclusion The use of PIEB technology for childbirth analgesia can achieve safe and effective analgesic effects,significantly reduce the dosage of anesthetic drugs,greatly improve maternal satisfaction,and will not affect delivery results.It is worth promoting.
