孕晚期NST反复异常与胎儿预后

Relationship of abnormal nonstress test repeatedly and neonatal prognosis

目的探讨妊娠晚期无应激试验与新生儿预后的关系。方法选取2009年1月-2011年9月笔者所在医院住院分娩且产前无应激试验异常2次以上孕妇200例(观察组),与随机抽取同期无应激试验正常孕妇200例(对照组)进行对照分析,并对新生儿预后进行评估。结果观察组和对照组新生儿1min评分≤7分,羊水污染等发生率前者明显高于后者,差异有统计学意义(P<0.05)。观察组脐带异常、羊水过少,明显高于对照组(P<0.05)。结论无应激试验反复异常提示胎儿宫内有不同程度缺氧。

Objective To study the relationship between fetal nonstress test （NST） and neonatal prognosis. Methods To select 200 patients with more than twice of abnormal NST as observed group and 200 cases with normal NST as control group, give the two groups A comparative analysis, and evaluate noonatal prognosis. Results It was significantly lower in control group than that in the observed group in rate of amniotic fluid contamination （P 〈 0.05 ）. The 1 min Neonatal Apgar score was ≤7. The observation group of umbilical cord ab- normalities, oligohydramnios was significantly higher than that of control group （ P 〈 0.05 ）. Conclusion Abnormal nonstress test repeated- ly can be used to predicate fetal anoxia.
