子宫肌电图（EMG）的功率谱（PS）可以识别真正的分娩。肌电图传播速度（PV）诊断分娩尚未见报道。目的是比较子宫肌电图与目前预测早产的方法。116例患者进行肌电图记录（早产20例，未产程早产儿68例，足月产程22例，足月非产程6例）。采用学生t检验比较产程与非产程的肌电图值（P<0.05）。采用受体-操作者-特征分析计算肌电图、bishop评分、子宫收缩图和经阴道宫颈长度的预测值。早产和足月分娩时PV高于未分娩时（P<0.001）。PV和PS峰值频率联合预测7天内早产，曲线下面积(AUC) = 0.96。Bishop评分、宫缩和宫颈长度的AUC分别为0.72、0.67和0.54。子宫肌电图PV和PS峰值频率比临床方法更准确地识别真早产。
Power spectrum (PS) of uterine electromyography (EMG) can identify true labor. EMG propagation velocity (PV) to diagnose labor has not been reported. The objective was to compare uterine EMG against current methods to predict preterm delivery. EMG was recorded in 116 patients (preterm labor, n=20; preterm non-labor, n=68; term labor, n=22; term non-labor, n=6). Student’s t-test was used to compare EMG values for labor vs. non-labor (P<0.05 significant). Predictive values of EMG, Bishop-score, contractions on tocogram, and transvaginal cervical length were calculated using receiver-operator-characteristics analysis. PV was higher in preterm and term labor compared with non-labor (P<0.001). Combined PV and PS peak frequency predicted preterm delivery within 7 days with area-under-the-curve (AUC) = 0.96. Bishop score, contractions, and cervical length had AUC of 0.72, 0.67, and 0.54. Uterine EMG PV and PS peak frequency more accurately identify true preterm labor than clinical methods.
