目的 分析低危首次妊娠孕妇分娩中会阴无保护接生技术的应用价值。方法 选取我院收治的低危首次妊娠孕妇102 例，随机分成常规组、研究组，每组各51例。常规组为传统接生技术，研究组为会阴无保护接生技术，比较两组的 会阴裂伤程度、产后出血量、新生儿窒息率以及产程疼痛程度。结果 ①研究组产后2小时出血量(161.29±93.49) ml低于常规组（179.48±92.43）ml，组别间比较有统计差异(P＜0.05)；②研究组的产程轻度疼痛率(76.47%)高 于常规组(47.06%)，中度疼痛率(23.53%)低于常规组(50.98%)，两组数据对比有差异(P＜0.05)；③研究组会阴I 级裂伤率高于常规组，II级裂伤率低于常规组，组别间比较有差异(P＜0.05)；④研究组新生儿窒息率低于常规组 (1.96% vs.13.73%)，两组有统计学意义(P＜0.05)。结论 在低危首次妊娠孕妇分娩过程中，通过实施会阴无保护 接生技术，能降低新生儿窒息率，控制产后出血量，值得临床推广。

Objective To analyze the application value of unprotected perineum delivery technique on the delivery of low risk primiparas. Methods A total of 102 low risk primiparas in our hospital were taken as the clinical objects, and they were randomly divided into conventional group (51 cases) and study group (51 cases). The conventional group was given conventional delivery technique, and the study group was given unprotected perineum delivery technique. The perineal laceration degree, postpartum blood loss, neonatal asphyxia rates and pain degree of birth process in the two groups were compared. Results Two hours after delivery, the blood loss in the study group was less than that in the conventional group[(161.29±93.49)ml vs.(179.48±92.43)ml)] , the difference was statistically significant(P<0.05). The mild pain rates of birth process in the study group were higher than that in conventional group (76.47% vs. 47.06%), and moderate the pain rate in study group was lower than that in conventional group, and their difference was statistically significant(P<0.05). In the study group, the perineal laceration rate of grade I was higher than that in the conventional group, and the perineal laceration rate of grade II was lower than that in the conventional group(23.53% vs. 50.98%, and the differences were statistically significant(P<0.05). The neonatal asphyxia rate in the study group was obviously lower than that in the conventional group (1.96% vs. 13.73%), and the difference was statistically significant(P<0.05). Conclusion In the delivery process of low risk primiparas, unprotected perineum delivery technique can not only reduce the neonatal asphyxia rate, but also control the amount of postpartum blood loss. Thus, it is worthy of application in clinic.
