Hemostasis in neonatal ECMO
Research article published in Frontiers in pediatrics (2022)
Abstract
Extracorporeal membrane oxygenation (ECMO) is a life-saving support for cardio-respiratory function. Over the last 50 years, the extracorporeal field has faced huge technological progress. However, despite the improvements in technique and materials, coagulation problems are still the main contributor to morbidity and mortality of ECMO patients. Indeed, the incidence and survival rates of the main hemorrhagic and thrombotic complications in neonatal respiratory ECMO are relevant. The main culprit is related to the intrinsic nature of ECMO: the contact phase activation. The exposure of the human blood to the non-endothelial surface triggers a systemic inflammatory response syndrome, which chronically activates the thrombin generation and ultimately leads to coagulative derangements. Pre-existing illness-related hemostatic dysfunction and the peculiarity of the neonatal clotting balance further complicate the picture. Systemic anticoagulation is the management's mainstay, aiming to prevent thrombosis within the circuit and bleeding complications in the patient. Although other agents (i.e., direct thrombin inhibitors) have been recently introduced, unfractionated heparin (UFH) is the standard of care worldwide. Currently, there are multiple tests exploring ECMO-induced coagulopathy. A combination of the parameters mentioned above and the evaluation of the patient's underlying clinical context should be used to provide a goal-directed antithrombotic strategy. However, the ideal algorithm for monitoring anticoagulation is currently unknown, resulting in a large inter-institutional diagnostic variability. In this review, we face the features of the available monitoring tests and approaches, mainly focusing on the role of point-of-care (POC) viscoelastic assays in neonatal ECMO. Current gaps in knowledge and areas that warrant further study will also be addressed.

Por qué esto importa para la hirudoterapia
Esta revisión describe cómo la activación por contacto de la sangre por la superficie no endotelial de la ECMO conduce a un estado inflamatorio sistémico y procoagulante, haciendo que los problemas de coagulación sean una fuente principal de morbilidad y mortalidad en la ECMO neonatal, y señala que la heparina no fraccionada sigue siendo el estándar mundial mientras que los inhibidores directos de la trombina se han introducido más recientemente y no existe aún ningún algoritmo de monitorización ideal. Su relevancia para la hirudoterapia reside en la historia del descubrimiento de fármacos: el secretoma de la lombriz medicinal es la fuente natural de hirudin, el inhibidor directo de la trombina prototipo cuyos descendientes sintéticos son la clase que los autores citan como alternativas más nuevas a la heparina en este escenario difícil de anticoagular. Como revisión narrativa centrada en la monitorización de la ECMO neonatal, resume el trabajo de otros y la incertidumbre actual en lugar de presentar nuevos datos comparativos, y no evalúa la terapia con lombrices ni ningún agente específicamente derivado de la lombriz en esta población.
