胎儿心电图与胎心率无负荷试验临床应用价值的比较

Contrast of clinical value in monitering FECG and NST of the rhythm of the fetus heart

目的探讨胎儿心电图（FECG），胎心率无负荷试验（NST）对胎儿监测的价值。方法采用随机抽样对317例（37-41w）孕妇分别于同日行胎儿心电图（FECG）胎心率无负荷试验（NST）监测，并结合超声检查及分娩后临床所见进行对比分析。结果FECG阳性率32％，NST阳性率为16％，对胎儿宫内危险因素的监测，胎儿心电图（FECG）较胎心率无负荷试验（NST）具有显著性意义（P〈0．01）。

Objective： We moniterecl FECG and NST of the rhythm of the fetus heart to find out their clinical values. Methods： 317 pergnant women （37w -41w） were randomized and monitered FECG and NST of rhythm of the fetus heart on the same day, and analized by combining the clinical show after parturition. Results： Positive rate of FECG is 32 percent; and positive rate of NST is 16 percent. The different is remarkable that the contrast of FECF and NST in monitering fetus＇s dangerous factors in uterus （ P 〈 0. 01 ）.
