BACKGROUND: Goal-directed hemostatic resuscitation based on thrombelastography has a survival benefit compared to conventional coagulation assays. While thrombelastography transfusion thresholds for patients at risk for massive transfusion (MT) have been defined, similar cutoffs do not exist for the other commonly used viscoelastic assay, rotational thromboelastometry (ROTEM). The purpose of this study was to develop ROTEM blood product thresholds in patients at risk for MT. METHODS: ROTEM was assessed in trauma activation patients admitted from 2010 to 2016 (n = 222)...

Transfusions of red blood cells (RBCs), platelets, and plasma are critical therapies for infants and neonates (particularly preterm neonates) in the neonatal intensive care unit, who are the most frequently transfused subpopulation across all ages. Although traditionally a significant gap has existed between the blood utilization and the evidence base essential to adequately guide transfusion practices in infants and neonates, pediatric transfusion medicine is evolving from infancy and gradually coming of age...

Adverse events (AEs) associated with blood transfusions, including component-specific red cell, platelet, and plasma products, have been extensively surveyed. In contrast, surveillance of AEs associated with hematopoietic stem cell (HSC) products in HSC transplantation (HSCT) has been less rigorous, even though HSC products include a diversity of immature and mature hematopoietic cells, substantial plasma, and dimethyl sulfoxide (DMSO) in the case of cryopreserved HSC products. HSC infusion-related AEs have been attributed to DMSO toxicity, but AEs associated with the infusion of noncryopreserved HSC products are not uncommon...

Human platelets play important roles in several physiologic and pathologic processes. Any defects in platelet number and function can lead to a variety of bleeding complications; platelet transfusions are commonly used to improve platelet count and hemostatic function in these cases. However, transfusions are complicated by the short storage life of donated platelets and contamination risks. Synthetic platelet substitutes can render efficient hemostasis while allowing advantages of large-scale preparation, minimum contamination risk via effective sterilization, longer shelf-life, no need for blood type matching, and reduced risks of biologic or pathologic side effects...

A prior Cesaria section (C-section) is an important risk factor that leads to endometrial damage and abnormal implantation of the placenta. Our retrospective study aims to correlate the frequency of placenta previa to previous C-sections, to determine the effect of male gender in this condition and to evaluate further the maternal outcome. Seventy-six cases with placenta previa were selected out of 5200 live births. Diagnosis was confirmed by ultrasound and in the operating theater. In the 76 women examined, we found 50 cases with a history of a previous C-section (66...

BACKGROUND: Hemorrhagic shock is a medical emergency that often complicates vascular surgery and can lead to death. Hemorrhagic shock is characterized by hypoperfusion and hemodynamic abnormalities leading to the collapse of homeostasis due to massive blood loss. Early diagnosis is critical for a favorable outcome. Thromboelastometry has been considered an effective tool for bleeding management in critically ill patients. Thromboelastometry can guide transfusion therapy quickly, reducing the need for blood products...

Intraoperative cell salvage (IOCS) for high-risk obstetric hemorrhage is now endorsed by a number of obstetric organizations. Most previous studies have focused on the safety of IOCS from case series and small controlled studies. Here, we describe the effect of IOCS on rates of allogeneic blood transfusion (ABT) under different degrees of bleeding during cesarean section in women with placenta accreta, which has seldom been reported in the literature.We conducted a retrospective analysis on the introduction of routine application of IOCS for the management of hemorrhage during cesarean section in women with placenta accreta...

The aim of pediatric transfusions should be based on the concept of avoiding unnecessary transfusions without jeopardizing the patient safety and providing correct blood components when there are well founded indications to transfuse. Despite considerable efforts from transfusion services to increase transfusion safety, transfusions are still associated with preventable and unpreventable adverse effects that may, in the worst case, have severe and fatal consequences. Transfusions to pediatric patients constitute a small proportion of all transfusions but have higher incidence of adverse events compared to adults...

REVIEW
Raymond P Goodrich, Jerard Segatchian
Pediatric patients requiring transfusion constitute one of the most challenging areas of transfusion practice. Due to the limitations posed by their particular physiological conditions they routinely require specialized component support and more personalised transfusion care than what is routinely utilized in the care of adult patients. Pediatric patients, unlike many adult patients requiring transfusion support, also generally have significant lifespans post-transfusion. This combined with the possibility of long term consequences to adverse events related to transfusion such as infection or change in immunological status drives the need to continue to use improved blood components in the transfusion support of pediatric patients...

Hemostasis is a complex dynamic process involving bleeding and thrombosis as two end-points. Conventional coagulation tests which are measured in plasma examine only isolated portions of the coagulation cascade, thereby giving no information on important interactions essential to the clinical evaluation of hemostatic function. Thromboelastography (TEG), originally described in 1948 has improved over the decades and become a valuable tool of coagulation testing because of the limitations of standard coagulation tests...

Patients with cirrhosis undergoing liver transplantation have unique challenges with regard to the prevention and management of thrombosis and hemorrhage. Patients with cirrhosis have an unstable balance of the coagulation system due to defects in both prothrombotic and antithrombotic components. These changes make laboratory monitoring challenging, prophylaxis against bleeding and thrombosis controversial, and therapy for the same uncertain. When cirrhotic patients undergo liver transplantation they frequently have significant transfusion requirements...
