胎心率监护在高危妊娠中的应用

Application of the fetal heart rate monitor in the high-risk pregnancy

目的探讨胎心率监护仪在高危妊娠中监测胎儿宫内情况的临床效果。方法采用胎儿心率电子监护仪对高危妊娠孕妇进行产前、产时监护,其中行无负荷试验(NST)68例,宫缩应激试验(CST)和催产素激惹试验(OCT)48例。结果 NST68例中反应型63例占92.65%,无反应型5例占7.35%,CST+OCT48例中阴性43例占89.58%,阳性5例占10.42%。NST反应型的高危妊娠孕妇胎儿宫内窘迫、新生儿窒息发生率、手术产率均明显低于NST无反应型的高危妊娠孕妇(P<0.05),CST+OCT阴性的高危妊娠产妇其胎儿宫内窘迫、新生儿窒息发生率及手术产率明显低于CST+OCT阳性的高危妊娠产妇(P<0.05)。结论胎儿心率电子监护仪对高危妊娠孕妇可增加异常胎儿心率的检出,早期发现胎儿宫内缺氧情况,有效降低新生儿窒息和早产的发生,提高临危胎儿的抢救成功率,降低围生儿的死亡率。

Objective To explore the clinical effects of the fetal heart rate monitor in a high-risk pregnancy to monitor fetal. Methods The pregnant women were used the fetal heart rate monitor to tutelage when they were in the ante partum and intrapartum,68 cases were being the Non stress test,48 cases were being the contyaction stress test and oxytocin challenge test. Results In NST68 cases,the reaction type with 63 cases accounting for 92.65%,the unresponsive type with 5 cases accounting for 7.35%.In CST ＋ in OCT48 cases,43 cases were negative accounting for 89.58%,5 cases were positive accounting for 10.42%.NST reaction type of high-risk pregnancy maternal fetal distress,neonatal asphyxia,operative delivery were significantly lower than the NST reactive high-risk pregnant women （P 〈 0.05）,the CST ＋ OCT negative high-risk pregnancy maternal fetal Palace inner distress,neonatal asphyxia,and operative delivery rate was significantly lower than the CST ＋ OCT positive risk pregnancy women （P 〈 0.05）. Conclusion Fetal heart rate the electronic detection of abnormal fetal heart rate monitor high-risk pregnant women can increase early detection of fetal hypoxia,reduce the incidence of neonatal asphyxia and premature birth,and improve the success rate of Threatened fetus,reducing preinstall children mortality.
