第二产程延长对母婴的影响及护理干预决策

目的探讨第二产程延长的原因及护理干预,并进行回顾性分析,分析第二产程延长对母婴的危害。方法选择60例第二产程延长分娩的病例(延长组),选择同期非第二产程延长病例60例作为对照组。比较两组的分娩方式,产后出血发生率以及新生儿窒息发生率。结果第二产程延长增加了阴道助产和剖宫产以及产后出血的发生率,两组相比差异有统计学意义(P<0.05);第二产程延长组增加了新生儿窒息发生率,两组差异有统计学意义(χ2=17.699,P=0.000);当第二产程延长时间超过3 h,新生儿窒息的发生率增加(P<0.01)。结论第二产程异常处理的关键在于针对造成产程异常的潜在因素进行干预。缩短第二产程,减少母婴损伤,降低新生儿窒息的发生。

Objective Discussing the causation of abnormalities in sencond stage of labor and relative nursing intervention. Moreover, conducting a retrospective analysis to look into the harm that Prolonged second stage of labor has on both monther and infantis.Methods Choose 60 prolonged delivery cases happened in this hospital Prolonged Group, and randomly pick another 60 hameochronous non-prolonged delivery cases as control group. Compering the delivery mode, postpartum haemorrhage rate and incidence rate of new born asphyxia between two groups. Results Prolonged second stage of labor increases the incidence rate of assist in vaginal delivery, caesarean and postpartum haemorrhage, the difference is statistically significant between two groups （P〈0.05）; prolonged second stage of labor increases the incidence rate of new born asphyxia, the difference between two goups is statistically significant （χ2=17. 699,P=0. 000）;the incidence rate of new born asphyxia increases when time of second stage of labor prolongates over 3 hours （P〈0.01）. Conclusion The key to handle abnormalities in second stage of labor is to direct apply intervention on relative potential pathogeny. Shortening the second stage of labor to reduce the harm on mother and infantis, and to reduce of incidence rate of new born asphyxia.
