OBJECTIVES: Postoperative bleeding in cardiac surgery remains an important complication, leading to increased morbidity and mortality. Different interventions are possible to prevent/treat postoperative bleeding. The present study aims to investigate the effectiveness of these interventions in a real-world scenario. METHODS: This is a retrospective study based on 19 670 consecutive adult cardiac surgery patients operated from 2000 to 2015. During the study period, the following interventions have been applied and tested for effectiveness with a before versus after analysis: thromboelastography (TEG)-based diagnosis and treatment in actively bleeding patients; platelet function tests (PFTs); timing of surgery based on PFTs; fresh frozen plasma (FFP)-free strategy using prothrombin complex concentrate and fibrinogen concentrate...

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To identify associations between abnormal coagulation profile and postoperative morbidity and mortality in patients undergoing posterior lumbar fusion (PLF). SUMMARY OF BACKGROUND DATA: The literature suggests that abnormal coagulation profile is associated with postoperative complications, notably the need for blood transfusion. However, there is little research that directly addresses the influence of coagulation profile on postoperative complications following PLF...

PURPOSE OF REVIEW: Death from uncontrolled haemorrhage is one of the leading causes of trauma-related mortality and is potentially preventable. Advances in understanding the mechanisms of trauma-induced coagulopathy (TIC) have focused attention on the role of blood products and procoagulants in mitigating the sequelae of TIC and how these therapies can be improved. RECENT FINDINGS: A host of preclinical and clinical studies have evaluated blood product availability and efficacy in trauma...

Intracerebral hemorrhage (ICH) remains a cause of death in hematologic malignancies. Asparaginase represents a key agent in the treatment of acute lymphoblastic leukemia (ALL). The toxicity of asparaginase includes coagulopathy such as thrombotic or bleeding tendency. We report a case of fatal cerebral hemorrhage in a 12-year-old girl treated for ALL. Cerebral hemorrhage occurred after three injections of L-asparaginase. The patient presented with hypofibrinogenemia (0.36g/L), associated with thrombocytopenia (24,000/mm(3))...

BACKGROUND: The majority of allogeneic transfusions occur in the perioperative setting, especially during cardiac surgery. In addition to the economic implications, there is emerging evidence that blood transfusion may increase both morbidity and mortality. Acute normovolemic hemodilution (ANH) may limit the need for blood products. OBJECTIVES: The primary objective of this study was to determine if the method of blood collection (syringe or bag) during the ANH process impacted the platelet count and function...

BACKGROUND: Moderate (MHCA) versus deep (DHCA) hypothermia for circulatory arrest in aortic arch surgery has been purported to reduce coagulopathy and bleeding complications, although there are limited data supporting this claim. This study aimed to compare bleeding-related events after aortic hemiarch replacement with MHCA versus DHCA. METHODS: Patients who underwent hemiarch replacement at a single institution from July 2005 to August 2014 were stratified into DHCA and MHCA groups (minimum systemic temperature ≤20°C and >20°C, respectively) and compared...

Lactic acidosis (LA) is a marker for mortality in severe malaria, but the mechanisms that lead to LA in the different types of severe malaria and the extent to which LA-associated mortality differs by type of severe malaria are not well described. We assessed the frequency of LA in children admitted to Mulago Hospital, Kampala, Uganda with cerebral malaria (CM, n = 193) or severe malarial anemia (SMA, n = 216). LA was compared to mortality and measures of parasite biomass and sequestration (P. falciparum histidine-rich protein-2 (PfHRP2) concentration, platelet count), and to a measure of systemic tissue oxygen delivery (hemoglobin level)...

INTRODUCTION: The Scottish Transfusion and Laboratory Support in Trauma Group (TLSTG) have introduced a unified National pre-hospital Code Red protocol. This paper reports the results of a study aiming to establish whether current pre-hospital Code Red activation criteria for trauma patients successfully predict need for in hospital transfusion or haemorrhagic death, the current admission coagulation profile and Concentrated Red Cell (CRC): Fresh Frozen Plasma (FFP) ratio being used, and whether use of the protocol leads to increased blood component discards? METHODS: Prospective cohort study...

ABO blood group antigen incompatibility (ABO mismatch) is not an obstacle to allogeneic stem cell transplantation (allo-SCT). However, the impact on clinical outcome after allo-SCT remains controversial. We analyzed 512 patients after allogeneic peripheral blood SCT (allo-PBSCT) for an association of ABO mismatch with transfusion requirements, myeloid and platelet engraftment, the incidence of GvHD, relapse, transplant-related mortality (TRM), and overall survival (OS). A total of 260 patients underwent ABO-mismatched transplantation and the control group consisted of 252 patients with ABO-matched allo-PBSCT...

Viscoelastic haemostatic assays (VHAs), mainly thromboelastography (TEG) and the rotational thromboelastometry (ROTEM), provide global information on clot formation and dissolution at patient bedside, allowing fast identification of coagulation disorders. In trauma patients, VHAs are able to predict massive transfusion and mortality. These devices might also be used for applying targeted administration of procoagulant factors (e.g. fibrinogen concentrate) as an alternative to or in addition to using predefined fixed ratios of red blood cells: platelets: fresh frozen plasma/cryoprecipitate...

BACKGROUND: We sought to examine the effect on blood usage of a new electronic order set restricting transfusion orders to specific evidence-based criteria for each unit (U) of red blood cells (RBC), plasma, and platelets. METHODS: Prospectively collected transfusion data for Trauma ICU patients were compared for the 12 months before (PRE) and 8 months after (POST) order set implementation. Criteria for RBC transfusion were 1 U only for hemoglobin <7 g/dL in stable patients or <8 g/dL with angina, myocardial infarction, or cardiogenic shock; 2 U for hemoglobin <5 g/dL; and multiple U in the presence of shock, hypotension, or bleeding...

BACKGROUND: Massive transfusion protocols (MTPs) to address hemorrhage are understudied in children. The objective was to determine the effect of MTP implementation on outcomes of injured children. STUDY DESIGN AND METHODS: This was a retrospective comparison of injured children before and after MTP implementation for children less than 18 years old who presented in 2005 to 2014 and received red blood cells (RBCs) within 24 hours of arrival. Children were divided into groups based on pre-/post-MTP implementation and subgrouped based on receipt of massive transfusion (≥40 mL/kg RBCs or ≥80 mL/kg total blood products at 24 hr from arrival)...

BACKGROUND: Severe bleeding and coagulopathy are serious clinical conditions that are associated with high mortality. Thromboelastography (TEG) and thromboelastometry (ROTEM) are increasingly used to guide transfusion strategy but their roles remain disputed. This review was first published in 2011 and updated in January 2016. OBJECTIVES: We assessed the benefits and harms of thromboelastography (TEG)-guided or thromboelastometry (ROTEM)-guided transfusion in adults and children with bleeding...

BACKGROUND: Platelet transfusions are used in modern clinical practice to prevent and treat bleeding in people with thrombocytopenia. Although considerable advances have been made in platelet transfusion therapy since the mid-1970s, some areas continue to provoke debate especially concerning the use of prophylactic platelet transfusions for the prevention of thrombocytopenic bleeding. OBJECTIVES: To determine whether agents that can be used as alternatives, or adjuncts, to platelet transfusions for people with haematological malignancies undergoing intensive chemotherapy or stem cell transplantation are safe and effective at preventing bleeding...
