摘要
目的:探讨超声评估前置胎盘患者生产时机及产后出血的临床价值。方法:回顾性分析瑞金市妇幼保健院2022年1月—2024年6月收治的前置胎盘患者116例。所有患者均接受超声检查,评估前置胎盘类型、血流信号、异常血管情况。根据超声检查结果确定个体化的生产时机和方式,并记录产后出血情况。结果:116例前置胎盘患者中,完全性前置胎盘占39.66%(46/116),平均生产孕周为(36.47±0.52)周,均采用剖宫产分娩;部分性前置胎盘占33.62%(39/116),平均生产孕周为(37.05±0.48)周,均采用剖宫产分娩;边缘性前置胎盘占26.72%(31/116),平均生产孕周为(37.62±0.35)周,其中14例行剖宫产,17例行阴道分娩。胎盘厚度>4 cm、血流信号丰富、存在异常血管患者的产后出血发生率高于胎盘厚度≤4 cm、血流信号正常、无异常血管患者(P<0.05)。结论:根据超声检查评估患者的前置胎盘类型、血流信号、异常血管情况可指导临床合理选择生产时机和方式。
Objective:To investigate the clinical value of ultrasound in evaluating the delivery timing and postpartum hemorrhage in patients with placenta previa.Method:A retrospective analysis was conducted on 116 patients with placenta previa admitted to Ruijin Maternal and Child Health Care Hospital from January 2022 to June 2024.All patients underwent ultrasound examination to assess the type of placenta previa,blood flow signals,and abnormal vascular conditions.Based on the ultrasound examination results,the individualized delivery timing and method were determined,and the postpartum hemorrhage was recorded.Result:Among the 116 patients with placenta previa,complete placenta previa accounted for 39.66%(46/116),the average gestational age at delivery was(36.47±0.52)weeks,and all were delivered by cesarean section.Partial placenta previa accounted for 33.62%(39/116),the average gestational age at delivery was(37.05±0.48)weeks,and all were delivered by cesarean section.Marginal placenta previa accounted for 26.72%(31/116),the average gestational age at delivery was(37.62±0.35)weeks,among them,14 cases underwent cesarean section and 17 cases underwent vaginal delivery.The incidence of postpartum hemorrhage in patients with placental thickness>4 cm,rich blood flow signals,and abnormal blood vessels were higher than those in patients with placental thickness≤4 cm,normal blood flow signals,and no abnormal blood vessels(P<0.05).Conclusion:Evaluating the type of placenta previa,blood flow signals and abnormal vascular conditions of patients based on ultrasound examination can guide the clinical practice to rationally select the timing and mode of delivery.
