This document updates the "Guidelines for the Administration of Blood Products: Transfusion of Infants and Neonates" published in 2002 by the French National Authority for Health (HAS). In doing so, it acknowledges changes in transfusion practices during the past decade, particularly with respect to safety issues and additional published transfusion-related guidelines. The major modifications concern irregular agglutinin screening indications before 4 months of age, a limitation of blood irradiation, and a non-recommendation for systematically checking for cytomegalovirus status...

INTRODUCTION: The transfusion-related respiratory complications, transfusion-related acute lung injury (TRALI) and transfusion-associated circulatory overload (TACO), are leading causes of transfusion-related morbidity and mortality. At present, there are no effective preventive strategies with red blood cell (RBC) transfusion. Although mechanisms remain incompletely defined, soluble biological response modifiers (BRMs) within the RBC storage solution may play an important role. Point-of-care (POC) washing of allogeneic RBCs may remove these BRMs, thereby mitigating their impact on post-transfusion respiratory complications...

REVIEW
Tina L Palmieri
Blood transfusion in burns larger than 20% total body surface area (TBSA) are frequent due to operative procedures, blood sampling, and physiologic response to burn injury. Optimizing the use of blood transfusions requires an understanding of the physiology of burn injury, the risks and benefits of blood transfusion, and the indications for transfusion. Age also plays a role in determining blood transfusion requirements. Children in particular have a different physiology than adults, which needs to be considered prior to transfusing blood and blood products...

Patient Blood Management underscores a fundamental shift from a product-centered approach to a patient-centric approach through timely application of evidence-based medical and surgical concepts designed to maintain hemoglobin concentration, optimize hemostasis, and minimize blood loss in an effort to improve patient outcome. In this concept, allogeneic blood transfusion is not viewed as the treatment of default for anemic patients, but one among many treatment modalities that should be weighed based on its merits-potentials risks and benefits-for the individual patient in the context of other alternatives...

Rh immunoprophylaxis for Rh-negative women requires an understanding of terminology used for Rh blood typing laboratory reports. The pathophysiology of Rh hemolytic disease of the fetus and newborn was elucidated by studies in rhesus monkeys. Subsequent studies revealed that the human blood group antigen responsible for Rh hemolytic disease of the newborn (D antigen) is related to, but different from, the rhesus monkey antigen. Weak expression of the D antigen on red cells, originally termed D, is currently reported by laboratories as a "serologic weak D phenotype," which can be further defined by RHD genotyping to be either an RHD weak D type or a partial D phenotype...

BACKGROUND: Cell-derived microparticles (MPs) are currently of great interest to screening transfusion donors and blood components. However, the current approach to counting MPs is not affordable for routine laboratory use due to its high cost. AIM: The current study aimed to investigate the potential use of flow-rate calibration for counting MPs in whole blood, packed red blood cells (PRBCs), and platelet concentrates (PCs). METHODS: The accuracy of flow-rate calibration was investigated by comparing the platelet counts of an automated counter and a flow-rate calibrator...

Recognition of the acute coagulopathy of trauma and the limits of reconstituting whole blood with conventional blood components has led to a radical change in the way trauma patients with severe injuries are resuscitated. Massive transfusion protocols (MTP) have evolved toward the administration of conventional blood components in fixed ratios. Administration of a 1:1:1 unit ratio of fresh frozen plasma to whole-blood-derived platelets to packed red blood cells is now the most common strategy and the stated goal of directors of >80% of the level I trauma centers in the United States...

Since their introduction into clinical practice in the early 1960s, viscoelastic point-of-care (POC) testing-thromboelastrography (TEG) and thromboelastrometry (ROTEM)-has become increasingly popular in intensive care units, operating rooms, and emergency room settings. As TEG has been an established POC viscoelastic testing modality for many years, there has been more research and analysis of its utility and ability to reduce transfusions in the general, cardiac, and liver surgical sectors compared with ROTEM...

In this research agenda on the acute and critical care management of trauma patients, we concentrate on the major factors leading to death, namely haemorrhage and traumatic brain injury (TBI). In haemostasis biology, the results of randomised controlled trials have led to the therapeutic focus moving away from the augmentation of coagulation factors (such as recombinant factor VIIa) and towards fibrinogen supplementation and administration of antifibrinolytics such as tranexamic acid. Novel diagnostic techniques need to be evaluated to determine whether an individualised precision approach is superior to current empirical practice...
