【摘要】目的:浅析血栓弹力图(TEG)联合血小板聚集率对血栓前状态(PTS)所致复发性流产(RSA)结局的预测价值。方法:研究周期为2020年1月—2022年7月,设计总样本57例RSA患者纳入观察组,57例健康体检人群纳入对照组。通过血栓弹力图指标、血小板聚集率与凝血指标对比,研判TEG联合血小板聚集率对PTS所致RSA结局的预测价值。结果:在R值、MA值、血小板聚集率与凝血指标方面,结果表明观察组优于对照组(P<0.05)。结论:经TEG联合血小板聚集率、凝血指标与血流变学指标,对PTS导致RSA患者具备明显的现实意义。

【Abstract】Objective: To analyze the predictive value of thromboelastography (TEG) combined with platelet aggregation rate on the outcome of recurrent spontaneous abortion (RSA) caused by prethrombotic state (PTS). Methods: The study period was from January 2020 to July 2022.A total of 57 patients with RSA were enrolled in the observation group and 57 healthy people were enrolled in the control group.In order to evaluate the predictive value of thrombelastogram combined with platelet aggregation rate on the outcome of RSA induced by PTS by comparing the indexes of thrombelastogram,platelet aggregation rate and coagulation index. Results: In terms of R value,MA value,platelet aggregation rate and coagulation index,the results showed that the observation group was superior to the control group(P<0.05). Conclusion: TEG combined with platelet aggregation rate,coagulation index and hemorheology index is of practical significance in patients with RSA caused by PTS.

復发性流产(recurrent spontaneous abortion,RSA)是一种妊娠并发症,指自然流产次数连续超过2次[1]。女性妊娠阶段机体内凝血状态随即发生变化,如凝血因子增加、抗凝物质、纤溶活性下降,该变化可在一定程度上预防分娩出血,但相应也会增加血栓风险[2-3]。临床认为可在某些情况下将RSA视为妊娠期间过度凝血反应导致的结果,过度凝血状态会形成胎盘微血栓,影响正常胎盘微循环,最终引起流产[4]。文章纳入我院于2020年1月—2022年7月收治的57例复发性流产患者与57例健康体检人群作为研究对象,评价血栓弹力图(thrombelastography,TEG)联合血小板聚集率对血栓前状态(prethrombotic state,PTS)导致RSA结局的预测价值,现将本次研究全部内容整理后作以下论述。
1.1 一般资料
研究周期为2020年1月—2022年7月,设计总样本57例复发性流产患者与57例健康体检人群。两组一般资料差异不大(P>0.05),具有可比性。纳入标准:①年龄≥18岁;②观察组同一伴侣RSA;③观察组连续≥3次孕12周内流产;④对照组孕产次≤2次,不存在不良孕产史,至少有1次正常妊娠史;⑤神志清楚、智力正常、能进行正常的语言交流,在知情同意愿意配合的原则下完成;⑥观察组患者未发生妊娠,就诊时处于未孕状态。排除标准:①近3个月内使用抗凝或者促纤溶药物;②染色体异常;③糖尿病;④生殖道感染。
