Perfil de tromboelastometría rotacional (ROTEM) en una cohorte de asistolia no controlada / Rotational thromboelastometry (ROTEM) profile in a cohort of asystole donors

Introducción: La hipoperfusión juega un papel central en el shock, y es un desencadenante de la coagulopatía. El estudio del perfil ROTEM durante la parada cardíaca prolongada podría ofrecer nuevos conocimientos sobre la fisiopatología de la coagulopatía por shock. Objetivo: Describir el perfil de tromboelastometría rotacional en una cohorte de donantes en asistolia y determinar la incidencia de hiperfibrinólisis. Diseño: Cohortes prospectivo. Incluimos 18 pacientes ingresados tras parada cardíaca extrahospitalaria no recuperada. Se recopiló el primer ritmo cardíaco registrado, los tiempos de parada y los de asistencia. Al ingreso se realizaron test de coagulación convencional y ROTEM (EXTEM, APTEM, FIBTEM) en los 30min tras la obtención de la muestra. Ámbito: El estudio se llevó a cabo en un hospital de tercer nivel incluido en un programa de donación en asistolia. Participantes: Pacientes en parada cardíaca extrahospitalaria no recuperada. Resultados: La mediana de edad fue de 50años y 14 de los participantes eran hombres (77,8%). La mediana de tiempo (rango intercuartílico) desde la parada hasta la obtención de muestras fue de 91min (75-104). Los resultados de la coagulación fueron: INR 1,25 (1,19-1,34), TTPA 55s (45-73) y fibrinógeno 161mg/dl (95-295). Los resultados del ROTEM (APTEM): CT 126s (104-191), CFT 247s (203-694). En 15 (83,3%) se cumplió el criterio de hiperfibrinólisis. También se observó mejoría del MCF en APTEM frente a EXTEM. Tiempos más prolongados se asociaron con niveles inferiores de fibrinógeno y un MCF FIBTEM inferior (p<0,05). Conclusiones: El análisis ROTEM mostró una profunda alteración en la formación del coágulo junto con alta incidencia de hiperfibrinólisis

Background: 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. Outcome: To describe the ROTEM profile in a cohort of asystole donors and elucidate the incidence of hyperfibrinolysis. Design: 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. Scope: An asystole donor reference hospital. Participants: Patients admitted to the ICU after out-of-hospital non-recovered CA. Results: 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). Conclusions: The ROTEM assays revealed severe alterations of the clot formation parameters and a high incidence of hyperfibrinolysis
