目的 分析单胎重度子痫前期(sPE)孕妇发生产后出血(PPH)的危险因素和有效预测指标,为临床预防sPE孕妇发生PPH提供参考依据。 方法 回顾性分析2016年1月1日至2022年12月31日在广州两所三甲医院住院分娩的932例sPE孕妇的临床资料,其中95例为sPE并发PPH孕妇,比较两组孕妇的临床资料。 结果 (1)sPE并发PPH组孕妇辅助生殖率、产程出血量、胎盘早剥发生率、D二聚体(DD)、单核细胞计数(MONO)、全身炎症反应指数(SIRI)水平高于重度子痫前期组,血小板计数(PLT)低于子痫前期组(P < 0.05)。(2)产时出血量、DD水平和血小板计数水平是sPE并发PPH孕妇的独立危险因素。(3)产时出血量、DD和血小板计数的ROC曲线下面积值(AUC)分别为0.805、0.717和0.571,DD的最佳截断值为2.295 μg/ mL。联合产时出血量以及DD两个指标的AUC为0.859。(4)sPE并发PPH孕妇的产时出血量值在阴道分娩和剖宫产两种分娩方式中,均高于PE组(P < 0.001),其对应的最佳截断值分别为285 mL和375 mL。 结论 产时出血量、DD水平和血小板计数水平是sPE并发PPH孕妇的独立危险因素。阴道分娩产时出血量> 285 mL、剖宫产产时出血量> 375 mL和DD > 2.295 μg/ mL的sPE孕妇发生PPH的风险较高。临床应加强对孕妇相关指标的监测。

Objective To analyze the risk factors and effective predictive indicators for postpartum hemorrhage (PPH) in pregnant women with severe pre-eclampsia (sPE) in singleton pregnancies. The findings will serve as a valuable reference for the clinical prevention and management of PPH in these patients. Methods A retrospective analysis was conducted on 932 pregnant women with sPE at two tertiary hospitals in Guangzhou from January 1, 2016, to December 31, 2022. Among these, 95 cases were complicated by PPH. A comparative analysis was performed between the sPE group and the sPE with PPH group. Results (1) The incidence of assisted reproductive technology, intrapartum blood loss, placental abruption, elevated D-dimer levels, increased monocyte counts, and higher SIRI levels were significantly higher in the PPH group, whereas platelet counts were significantly lower (P < 0.05). (2) The results indicated that intrapartum blood loss, D-dimer levels, and platelet counts were independently associated with PPH in pregnant women with sPE. (3) The area under the curve (AUC) for intrapartum blood loss, D-dimer, and platelet counts were 0.805, 0.717, and 0.571, respectively. The optimal cutoff value for D-dimer was determined to be 2.295 μg/mL. The combined AUC for intrapartum blood loss and D-dimer was 0.859. (4) Intrapartum blood loss values were significantly higher in the PPH group for both vaginal delivery and cesarean section (P < 0.001). The corresponding optimal cutoff values were 285 mL and 375 mL, respectively. Conclusions Intrapartum haemorrhage, D-dimer levels, and platelet count were identified as independent risk factors for PPH in pregnant women with sPE. Specifically, pregnant women with sPE who experienced blood loss exceeding 285 mL during vaginal delivery or 375 mL during caesarean section, along with a D-dimer level greater than 2.295 μg/mL, demonstrated an increased likelihood of developing PPH. Therefore, it is crucial to enhance clinical monitoring of these relevant indicators in high-risk populations.
