Mil Med 2024:usae430.

Abstract
INTRODUCTION Absence of pre-hospital coagulation tests challenges prompt management of hemostasis after trauma. The Viscoelastic Coagulation Monitor (VCM, Entegrion, Durham, NC) is a hand-held coagulation test for point-of-care. We evaluated VCM in a translational swine polytrauma model, hypothesizing that VCM correlates with a laboratory reference method, the TEG 5000 (Haemonetics, Boston, MA), and can identify coagulopathic phenotypes relevant to trauma. Our secondary hypothesis was that pre-warming of VCM disposable test cartridges using a heating plate versus pre-warming of cartridges by carrying the cartridge in the user's pocket does not significantly alter results. MATERIALS AND METHODS This study was conducted in tandem with a parent study involving anesthetized, mechanically ventilated swine (n = 20; 54 ± 5 kg) that encountered traumatic brain injury, pulmonary contusion and hemorrhage, or combination/polytrauma injury. Blood was collected at baseline, post-injury, post-shock, post-transfusion, and 6-, 24-, and 48 h post-injury to perform VCM at point-of-care. Within-group effect of time was assessed. Spearman correlation examined linear relations between VCM and standard laboratory-based coagulation tests; as well as lactate, ionized calcium, and body temperature. Logistic regression examined predictiveness of VCM to identify coagulopathic phenotypes, with receiver operator characteristic curves generated to assess diagnostic capability. At a subset of timepoints, necessity of pre-warming the VCM test cartridge using a heating plate versus pre-warming the cartridge by placement in the user's pocket was assessed by conducting simultaneous tests on two separate instruments, with results analyzed by paired t-test with crossover design. RESULTS VCM revealed time-dependent changes in clotting time, clot formation time (CFT), alpha, maximum clot firmness (MCF), and lysis index (LI30). All VCM metrics correlated with the respective TEG 5000 metrics, with strongest correlation for VCM MCF with TEG MA (rhos = 0.77, P < .0001) and VCM LI30 with TEG LY30 (rhos = -0.76, P < .0001). VCM demonstrated good (area under the curve >0.70) to excellent (area under the curve >0.90) diagnostic accuracy in detection of low platelet count (MCF), low hematocrit (clotting time, clot formation time, alpha, and MCF), low fibrinogen (MCF), and high fibrinogen (alpha, MCF). There was no statistically or clinically relevant effect of cartridge warming method on results. CONCLUSIONS In a trauma model, VCM detected significant changes in coagulation at point-of-care in a simplified portable form factor. VCM could enable informed hemostasis management in pre-hospital settings where coagulations tests are unavailable, pending further validation in clinical trials.

Viscoelastic coagulation testing in Neonatal Intensive Care Units: advantages and pitfalls in clinical practice. BLOOD TRANSFUSION = TRASFUSIONE DEL SANGUE 2023; 21:538-548. [PMID: 36795342 PMCID: PMC10645350 DOI: 10.2450/2023.0203-22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Accepted: 12/01/2022] [Indexed: 02/17/2023]
Abstract
The expression "developmental hemostasis" indicates the age-related physiological changes occurring during the maturational process of the hemostatic system. Despite the quantitative and qualitative alterations, the neonatal hemostatic system is competent and well-balanced. Conventional coagulation tests do not provide reliable information as they only explore the procoagulants during the neonatal period. In contrast, viscoelastic coagulation tests (VCTs), such as viscoelastic coagulation monitoring (VCM), thromboelastography (TEG or ClotPro), and rotational thromboelastometry (ROTEM), are point-of-care assays that provide a quick, dynamic and global view of the hemostatic process, allowing prompt and individualized therapeutic intervention when necessary. Their use in neonatal care is on the increase and they could help monitor patients at risk of hemostatic derangement. In addition, they are crucial for anticoagulation monitoring during extracorporeal membrane oxygenation. Moreover, implementing VCT-based monitoring could optimize blood product use.

Abstract
Cryoprecipitate is a transfusion blood product derived from fresh-frozen plasma (FFP), comprised mainly of the insoluble precipitate that gravitates to the bottom of the container when plasma is thawed and refrozen. It is highly enriched in coagulation factors I (fibrinogen), VIII, and XIII; von Willebrand factor (vWF); and fibronectin. In this article, we have reviewed currently available information on the preparation, properties, and clinical importance of cryoprecipitate in treating critically ill neonates. We have searched extensively in the databases PubMed, Embase, and Scopus after short-listing keywords to describe the current relevance of cryoprecipitate.

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.

Abstract
Millions of infants are born prematurely every year worldwide. Prematurity, particularly at lower gestational ages, is associated with high mortality and morbidity and is a significant global health burden. Pregnancy complications and preterm birth syndrome strongly impact neonatal clinical phenotypes and outcomes. The vascular endothelium is a pivotal regulator of fetal growth and development. In recent years, the key role of uteroplacental pathologies impairing endothelial homeostasis is emerging. Conditions leading to very and extremely preterm birth can be classified into two main pathophysiological patterns or endotypes: infection/inflammation and dysfunctional placentation. The first is frequently related to chorioamnionitis, whereas the second is commonly associated with hypertensive disorders of pregnancy and fetal growth restriction. The nature, timing, and extent of prenatal noxa may alter fetal and neonatal endothelial phenotype and functions. Changes in the luminal surface, oxidative stress, growth factors imbalance, and dysregulation of permeability and vascular tone are the leading causes of endothelial dysfunction in preterm infants. However, the available evidence regarding endothelial physiology and damage is limited in neonates compared to adults. Herein, we discuss the current knowledge on endothelial dysfunction in the infectious/inflammatory and dysfunctional placentation endotypes of prematurity, summarizing their molecular features, available biomarkers, and clinical impact. Furthermore, knowledge gaps, shadows, and future research perspectives are highlighted.
