Hypoperfusion plays a central role in shock states, and has been proposed as a coagulopathy trigger. The study of the rotational thromboelastometry (ROTEM) profile during cardiac arrest could offer new insights to the role of hypoperfusion in coagulation during shock states.
To describe the ROTEM profile in a cohort of asystole donors and elucidate the incidence of hyperfibrinolysis.
A prospective observational study was carried out in 18 patients consecutively admitted to the ICU after out-of-hospital non-recovered cardiac arrest (CA). Initial rhythm and time between CA and admission were recorded. Conventional coagulation and ROTEM (EXTEM, APTEM, FIBTEM) tests were performed within 30minutes after blood sample collection.
An asystole donor reference hospital.
Patients admitted to the ICU after out-of-hospital non-recovered CA.
The median age was 50years, and 14 of the patients were men (77.8%). The time from CA to hospital admission expressed as the median (interquartile range) was 91minutes (75-104). The results of the routine tests were: INR 1.25 (1.19-1.34), aPTT 55s (45-73) and fibrinogen 161mg/dl (95-295). For the ROTEM APTEM assay the results were: CT 126s (104-191), CFT 247s (203-694). Hyperfibrinolysis criteria were recorded in 15 patients (83.3%). In addition, MCF improved in APTEM versus EXTEM. Prolonged CA times were associated to lower fibrinogen levels and lower values for MCF FIBTEM (P<.05).
The ROTEM assays revealed severe alterations of the clot formation parameters and a high incidence of hyperfibrinolysis.
低灌注在休克状态中起核心作用，并被认为是凝血病的触发因素。研究心脏骤停期间的旋转血栓弹力图（ROTEM）特征可为低灌注在休克状态下凝血过程中的作用提供新见解。
描述一组心脏停搏供体的ROTEM特征，并阐明高纤溶的发生率。
对18例院外心脏骤停（CA）未恢复后连续入住重症监护病房（ICU）的患者进行前瞻性观察研究。记录初始心律以及CA与入院之间的时间。在采集血样后30分钟内进行常规凝血和ROTEM（EXTEM、APTEM、FIBTEM）检测。

院外心脏骤停未恢复后入住ICU的患者。
中位年龄为50岁，14例患者为男性（77.8%）。从CA到入院的时间，以中位数（四分位间距）表示为91分钟（75 - 104）。常规检测结果为：国际标准化比值（INR）1.25（1.19 - 1.34），活化部分凝血活酶时间（aPTT）55秒（45 - 73），纤维蛋白原161mg/dl（95 - 295）。对于ROTEM的APTEM检测，结果为：凝血时间（CT）126秒（104 - 191），凝血形成时间（CFT）247秒（203 - 694）。15例患者（83.3%）记录到高纤溶标准。此外，与EXTEM相比，APTEM中的最大凝血块硬度（MCF）有所改善。CA时间延长与较低纤维蛋白原水平以及MCF FIBTEM较低值相关（P<0.05）。
ROTEM检测显示凝血形成参数严重改变以及高纤溶发生率高。
