血液学血液学血液学
临床诊断临床诊断临床诊断临床诊断

背景情况:

目前产后出血 (PPH) 的定义缺乏一致性,预测工具不足.
旋转性血栓形成仪 (ROTEM) 为及时干预提供实时凝血评估.
需要创新的方法来准确预测个人PPH风险.

研究的目的:

调查ROTEM参数对个人PPH风险的预测效用.
为了评估ROTEM测量和实际流血之间的相关性.

主要方法:

一项前性观察队列研究,涉及92名经历剖腹产或阴道分娩的妇女.
在手术前测量ROTEM EXTEM参数 (CT,CFT,alpha角度,A10,A20,MCF,最大溶解).
纳入标准:18至50岁,怀孕34周以上,按计划分娩.

主要成果:

血液流失的重要预测因素包括年龄,分娩方式,妊娠年龄和最大溶解.
最大溶解的1%增加与44毫升增加的血液损失相关.
剖腹产的平均流血量比阴道分娩多522毫升.

结论:

在ROTEM EXTEM最大溶解参数显著影响血液损失.
需要进一步的大规模试验和参考值定义来优化ROTEM用于PPH预测.
ROTEM有可能指导早期干预措施,以预防严重的产科出血.
