Study on the Application of Three-dimensional Navigation System for the Delivery Process in Elderly Parturients and Its Impact on the Delivery Process and Pregnancy Outcomes

目的:探讨产程三维导航系统在高龄产妇中的应用及对产程和妊娠结局的影响。方法:选择2020年4月—2021年6月广州市花都区人民医院产科收治的高龄产妇60例为研究对象,按随机数字表法将其分为两组,各30例。所有产妇均拟行阴道分娩,对照组采用传统方法监测,观察组采用产程三维导航系统监测。比较两组产妇胎先露下降情况、产时出血量、产后2 h出血量、阴道分娩者产程时间、新生儿Apgar评分、妊娠结局。结果:观察组胎先露下降情况优于对照组,产时出血量、产后2 h出血量均少于对照组,差异均有统计学意义(P<0.05);两组产钳助产率、新生儿出生1 min Apgar评分比较,差异均无统计学意义(P>0.05);观察组阴道分娩率高于对照组,剖宫产率、新生儿胎儿窘迫和新生儿窒息发生率均低于对照组,差异均有统计学意义(P<0.05);观察组阴道分娩者第一、二产程均短于对照组阴道分娩者,差异均有统计学意义(P<0.05)。结论:产程三维导航系统用于高龄产妇中,能减少产时出血量、产后2 h出血量及动态监测胎先露下降的水平,提高新生儿Apgar评分,能有效提高高龄产妇阴道分娩率,缩短阴道分娩产程,降低剖宫产率、新生儿胎儿窘迫和新生儿窒息发生率。

Objective:To investigate the application of three-dimensional navigation system for the delivery process in elderly parturients and its impact on the delivery process and pregnancy outcomes.Method:Sixty elderly parturients admitted to the Obstetrics Department of Huadu District People's Hospital of Guangzhou from April 2020 to June 2021 were selected as the research subjects.They were randomly divided into two groups using a random number table method,with 30 cases in each group.All the parturients planned to have vaginal delivery.The control group was monitored by traditional methods,and the observation group was monitored by three-dimensional navigation system for the delivery process.The decreased fetal presentation,intrapartum blood loss,2 h postpartum blood loss,labor duration of vaginal delivery,neonatal Apgar score and pregnancy outcome were compared between the two groups.Result:The decreased fetal presentation in the observation group was better than that in the control group,the intrapartum and 2 h postpartum blood loss were less than those of the control group,the differences were statistically significant(P<0.05).There were no significant differences in the vaginal delivery rate and Apgar score at 1 min after birth between the two groups(P>0.05).The rate of natural delivery in observation group was higher than that in control group,and the incidences of cesarean section,fetal distress and neonatal asphyxia in observation group were lower than those in control group,the differences were statistically significant(P<0.05).The first and second stages of vaginal delivery in the observation group were shorter than those in the control group,the differences were statistically significant(P<0.05).Conclusion:The use of a three-dimensional navigation system for the delivery process in elderly parturients can reduce bleeding during delivery,2 hour postpartum bleeding,and dynamically monitor the level of decreased fetal presentation.It can improve the Apgar score of newborns,effectively improve the vaginal delivery rate of elderly parturients,shorten the vaginal labor process,and reduce the incidence of cesarean section,neonatal fetal distress,and neonatal asphyxia.
