目的 本研究旨在分析瘢痕子宫再次妊娠时血栓弹力图(thromboelasmography,TEG)及红细胞分布宽度变异系数(red blood cell distribution width coefficient of variation,RDW-CV)、中性粒细胞/淋巴细胞比值(neutrophil to lymphocyte rat...目的 本研究旨在分析瘢痕子宫再次妊娠时血栓弹力图(thromboelasmography,TEG)及红细胞分布宽度变异系数(red blood cell distribution width coefficient of variation,RDW-CV)、中性粒细胞/淋巴细胞比值(neutrophil to lymphocyte ratio,NLR)、单核细胞/淋巴细胞比值(monocyte lymphocyte ratio,MLR)以及全身免疫炎症指数(systemic immune-inflammation index,SII)等指标的变化情况,探讨凝血相关指标及炎症相关指标对瘢痕子宫再次妊娠风险预测价值。方法 回顾2021年3月1日至2024年3月1日在延安市人民医院产科住院的孕妇临床资料168例。比较瘢痕子宫不同妊娠阶段TEG及RDW-CV、NLR、MLR、SII等炎症指标的变化;比较瘢痕子宫孕妇与健康孕妇TEG及RDW-CV、NLR、MLR、SII等炎症指标的变化情况。结果 瘢痕子宫孕妇中,与中孕组相比,晚孕组孕妇TEG中的R值增加,Angle角、MA值减少(均P<0.05);NLR、MLR增高(P<0.05)。瘢痕子宫孕妇与健康孕妇相比,瘢痕子宫TEG中的R值、K值、Angle角、MA值的差异无统计学意义(均P>0.05);NLR、MLR差异有统计学意义(P<0.05)。结论 瘢痕子宫再次妊娠对TEG及部分炎症指标有影响,随着孕周数增加TEG指标与炎症指标有所变化;TEG及炎症指标联合检测可对瘢痕子宫再次妊娠风险作出预测。展开更多
