胎儿电子中央监护在产程中的应用

Using fetal central monitor system to predict fetal distress

目的 观察胎儿电子中央监护系统对预测胎儿宫内窘迫的作用。方法 对2006年4月～2007年3月在我院分娩的≥37周的2592例孕妇（监护组）进行产前、产时胎儿电子监护，其中作NST900例，CST或OCT 918例，并与2003年4月～2004年3月在我院分娩的≥37周未行胎儿电子监护的2376例孕妇（对照组）进行比较，并作统计学分析。结果 监护组与对照组胎儿窘迫发生率分别为16．9％、10．2％，新生儿窒息发生率分别为1．4％、2．7％，剖宫产率分别为26．8％、25．5％，NST无反应型、CST或OCT阳性的孕妇其胎儿窘迫，新生儿窒息、剖宫产率明显高于NST反应型、CST或OCT阴性的孕妇。结论 胎儿电子中央监护对诊断胎儿窘迫具有较高的临床意义，新生儿窒息率明显下降，不增加剖宫产率。

Objective To investigate the use of fetal central monitor system（FCMS） for the diagnosis of fetal distress. Methods 2592 women in childbirth（mornitoring group） were whole course mornitored by FCMS from April of 2006 to March of 2007.900 cases of these women were mornitored by NST and 918 by CST or OCT. 2376 women in childbirth（compared group） were mornitored by traditional methed from April of 2003 to March of 2004. Fetal distress, neonatal asphyxia and cesarean delivery in both groups were analyzed statistically. Result The incidence of fetal distress, neonatal asphyxia and cesarean delivery in mornitoring group and controlled group were 16.9% and 10.2%1.4% and 2.7%, 26.8% and 25.5% respectively. The ratio of fetal distress, neonatal asphyxia and cesarean delivery in women who had normal NST and positive CST or OCT were significantly higher than in women who had abnormal NST and negetive CST or OCT. Conclusion FCMS is useful in diagnosis of fetal distress. By using FCMS, the ratio of neonatal asphyxia decrease significantly, meanwhile, request of cesarean delivery is not increased.
