| 目的 应用会阴三维超声评估胎头方向角和胎头下降距离及用于预测分娩方式。方法选取于2016年1~6月在我院分娩的孕妇作为研究对象,应用会阴三维超声分别评估第1产程和第2产程胎头方向角和胎头下降距离,分析其与分娩方式的关系。结果第1产程胎头方向角和第2产程胎头下降距离与内诊检查胎先露最低点位置呈线性关系。当孕妇的胎头方向角＞120°、第2产程胎头下降距离＞40 mm时,孕妇经阴道分娩的可能性较大。第1产程HD1≤120°或＞120°,第2产程HPD2≤40 mm或＞40 mm时,自然分娩率差异有统计学意义(P＜0.05)。结论应用会阴三维超声评估胎头方向角和胎头下降距离,用于预测分娩方式可行。 |

| Objective To assess the head direction and head progression distance using intrapartum three-dimensional ultrasound and to predict the mode of delivery.MethodsThe pregnants during January to June in 2016 were selected as the subjects.The first and second stage of head direction and head progression distance were evaluated by intrapartum three-dimensional ultrasound.The relationship between head direction and head progression distance and delivery mode was analyzed. ResultsIt revealed a linear relationship between head direction of the first stage and the head progression distance of the second stage and the lowest point position.When the first stage of progression angel>120 °,the second stage of progression distance >40 mm,the possibility of vaginal delivery is greater.There were significant differences between HD1≤120°and HD1>120°of the first stage of labor,and that between HPD2≤40 mm and HPD2>40 mm of the second stage of labor (P<0.05).ConclusionThe application of intrapartum three-dimensional ultrasound to evaluate the head direction and head progression distance,is feasible for the prediction of delivery mode. |
