本文对319例单胎足月孕妇进行振动声音刺激试验(VAS—T)及声刺激引起的胎动(SPFM)与传统的无负荷试验(NST)对预测胎儿预后的临床意义进行前瞻性对比研究。结果三者的阴性预测价值及敏感性均很高。VAS—T及SPFM的特异性、阳性预测价值均明显高于NST,而假阳性率显著低于NST,且大大缩短了试验时间,表明VAS—T及SPFM是有效、简便、省时、经济的产前胎儿监护方法。
This study prospectively compared the clinical significance of VAS-T, SPFM and traditional non-stress test (NST) in predicting fetal prognosis in 319 singletonic term pregnant women. Results of the three negative predictive value and sensitivity are high. The specificity and positive predictive value of VAS-T and SPFM were significantly higher than that of NST, while the false positive rate was significantly lower than that of NST, and the test time was greatly shortened, indicating that VAS-T and SPFM were effective, simple, time-saving and economical Prenatal fetal monitoring methods.
