Objective: To quantitatively evaluate the clinical effects of Doula labor analgesia meter on the vaginal delivery. Methods: A total of 2 313 cases of full-term pregnancy vaginal trial delivery maternal were selected in our hospital from October 2014 to July 2015. According to the mode of delivery, patients are divided into control group (n=1 252), observation group A (n=705) and observation group B (n=356). The control group were given conventional vaginal delivery method, observation group A were given epidural analgesia labor measures, and the observation group B were given T-4A-type doula labor analgesia meter. hTe maternal mode of delivery, duration of labor, delivery and the degree of pain and birth outcomes for mother and child in these groups were observed successively.Results:hTe labor pain level of observation group A and observation group B were better than control group, with statistical significance (P<0.05), but there was no significant difference between the two groups (P>0.05). The maternal labor time, the rate of vaginal delivery, postpartum hemorrhage 2 h status in observation group B were signiifcantly better than those in the control group and observation group A, with statistical signiifcance (P<0.05).Conclusion: hTe implementation of doula labor analgesia meter can signiifcantly shorten the maternal labor time, relieve pain and improve productivity in the probability of vaginal delivery, maternal and neonatal safety of birth also has an active security role.%目的：量化评价阴道分娩产妇采用分娩镇痛导乐仪的临床效果。方法：选取本院2014年10月至2015年7月收治的2313例足月妊娠阴道试产孕产妇，根据其分娩模式将其分为对照组1252例、观察A组705例与观察B组356例。对照组采用常规阴道分娩方式，观察A组给予硬膜外麻醉镇痛分娩措施，观察B组应用GT-4A型分娩镇痛导乐仪，依次观察并比较各组孕产妇的分娩方式、产程时间、产中疼痛程度以及母婴分娩结局。结果：观察A组与观察B组产妇的各产程疼痛程度均明显好于对照组，具有统计学意义(P<0.05)，但两组产妇比较无统计学差异(P>0.05)。观察B组产妇的产程时间、阴道分娩率以及产后2 h出血量均显著好于对照组与观察A组，具有统计学意义(P<0.05)。结论：针对产妇采用分娩镇痛导乐仪可明显缩短产程时间、缓解产中疼痛并提升阴道分娩几率，对产妇与新生儿的分娩安全也具有积极保障性作用。
