OBJECTIVE Blood loss and moderate anemia are common in patients with traumatic brain injury (TBI). However, despite evidence of the ill effects and expense of the transfusion of packed red blood cells, restrictive transfusion practices have not been universally adopted for patients with TBI. At a Level I trauma center, the authors compared patients with TBI who were managed with a restrictive (target hemoglobin level > 7 g/dl) versus a liberal (target hemoglobin level > 10 g/dl) transfusion protocol. This study evaluated the safety and cost-efficiency of a hospital-wide change to a restrictive transfusion protocol...

BACKGROUND: Identifying trauma patients that need emergent blood product transfusion is crucial. The Trauma Induced Coagulopathy Clinical Score (TICCS) is an easy-to-measure score developed to meet this medical need. We hypothesized that TICCS would assist in identifying patients that need a transfusion in a large cohort of severe trauma patients from the TraumaRegister DGU(®) (TR-DGU). MATERIALS AND METHODS: A total of 33,385 severe trauma patients were extracted from the TR-DGU for retrospective analysis...

Outpatient anticoagulation in the geriatric trauma patient is a challenging clinical problem. The aim of this study is to determine clinical outcomes associated with class of preinjury anticoagulants (PA) used by this population. This is a multicenter retrospective cohort study among four Level II trauma centers. A total of 1642 patients were evaluated; 684 patients were on anticoagulation and 958 patients were not. Patients on PA were compared with those who were not. Drug classes were divided into thromboxane A2 inhibitors, vitamin K factor-dependent inhibitors, antithrombin III activation, platelet P2Y12 inhibitors, and thrombin inhibitors...

OBJECTIVES: We aimed to determine whether (1) tranexamic acid (TXA) reduces the incidence of transfusion (2) TXA reduces the calculated blood loss, and (3) there are any observable differences in 30- and 90-day complications with TXA administration during arthroplasty for femoral neck fracture (FNF). DESIGN: Prospective, double-blinded, randomized controlled trial. SETTING: Level 1 Academic Trauma Center. PATIENTS/PARTICIPANTS: One hundred thirty-eight patients who presented with a low-energy, isolated, FNF (AO 31B) treated with either hemi- or total hip arthroplasty within 72 hours of injury were randomized to either the TXA group (69 patients) or placebo group (69 patients)...

Massive traumatic haemorrhage is aggravated through the development of trauma-induced coagulopathy, which is managed by plasma transfusion and/or fibrinogen concentrate administration. It is yet unclear whether these treatments are equally potent in ensuring adequate haemostasis, and whether additional factor XIII (FXIII) administration provides further benefits. In this study, we compared ROTEM whole blood coagulation profiles after experimental massive transfusion with different transfusion regimens in an in vitro model of dilution- and transfusion-related coagulopathy...

REVIEW
Henry Liu, Ling Yu, Longqiu Yang, Michael S Green
Vasoplegic syndrome (VS) is increasingly recognized as an important clinical entity in perioperative medicine. VS is characterized by significant arterial hypotension, normal or high cardiac output, low systemic vascular resistance, and increased requirements for intravenous volume and vasopressors. Tremendous variations exist regarding incidence reported in the literature and management at different institutions; and the incidence of VS is likely significantly higher than many anesthesiologists believe. Thus the aims of this article are to review the pertinent aspects related to VS and alert clinical anesthesiologists to this under-recognized yet very challenging clinical condition...

BACKGROUND: Reductions in platelet (PLT) count and function are associated with poor outcomes in trauma patients. We proposed to determine if patients expected to receive blood products have a decrease in PLT function higher than expected based on the reduction in PLT count, and if the reduction in function could be associated with the donor plasma/supernatant received. METHODS: PLT count and function were measured on admission to the emergency department and intensive care unit in severely injured patients expected to receive a transfusion...

The aim of the study was to evaluate the treatment of minimally invasive mitral valve replacement (MIMVR) through a right minithoracotomy for patients with rheumatic mitral valve disease.From February 2009 to December 2016, 360 patients with rheumatic mitral valve disease underwent mitral valve replacement by the same surgeon. Among them, 150 patients accepted MIMVR through a right minithoracotomy, whereas the other 210 accepted a traditional median sternotomy. After matching by patients by age, sex, EuroSCORE, New York Heart Association (NYHA) classification, renal and liver function, and degree of mitral valve disease, we selected 224 patients for analysis in our retrospective study...

Malignant melanoma (MM) is the most aggressive and uneasily treatable form of skin cancer. Up to 90% of deaths because of skin tumours are estimated to be caused by this malignancy. Spontaneous regression is described as a partial or complete disappearance of cancer. It can be defined if the clinical and histological diagnosis of malignancy is verified and any therapeutic intervention potentially inducing mechanisms leading to regression has not been applied. Regression occurs more frequently in melanoma than in other types of tumours; it is reported to be six times higher than in other malignancies...

BACKGROUND: The 2009 NHS Blood and Transplant national comparative audit on blood use following primary total hip arthroplasty (THR) highlighted that preoperative anaemia was common and undertreated. They recommended that hospitals have a written policy for treating anaemia preoperatively. In our centre, we found that preoperative optimisation of anaemia, significantly reduced blood transfusion rate to <5%. The 2015 national audit showed that even though 48% of patients received tranexamic acid, 85% of patients required transfusion...

BACKGROUND: Use of universally ABO-compatible group AB plasma for trauma resuscitation can be challenging due to supply limitations. Many centers are now using group A plasma during the initial resuscitation of traumatically injured patients. This study was undertaken to evaluate the impact of this practice on mortality and hospital length of stay (LOS). STUDY DESIGN AND METHODS: Seventeen trauma centers using group A plasma in trauma patients of unknown ABO group participated in this study...

A positive direct antiglobulin test has been reported in 1:1000 to 1:14,000 blood donors and 1-15 % of hospital patients. Drugs may cause a positive direct antiglobulin test result and/or immune-mediated haemolysis with an incidence of approximately 1 in a 1 million population. Our aim is to highlight the importance of following strict transfusion protocols and management insight in a direct antiglobulin test positive patient showing incompatibility with multiple units possibly due to drug induced immune haemolytic anaemia (DIIHA)...

BACKGROUND: Up to 40% of combat casualties with a truncal injury die of massive hemorrhage before reaching a surgeon. This hemorrhage can be prevented with damage control resuscitation (DCR) methods, which are focused on replacing shed whole blood (WB) by empirically transfusing blood components in a 1:1:1:1 ratio of platelets:plasma:erythrocytes:cryoprecipitate (PLT:FFP:RBC:CRYO). Measurement of hemostatic function with thromboelastometry (ROTEM) may allow optimization of the type and quantity of blood products transfused...

BACKGROUND: Prolonged storage of packed red blood cells (PRBCs) may increase morbidity and mortality, and patients having massive transfusion might be especially susceptible. We therefore tested the hypothesis that prolonged storage increases mortality in patients receiving massive transfusion after trauma or nontrauma surgery. Secondarily, we considered the extent to which storage effects differ for trauma and nontrauma surgery. METHODS: We considered surgical patients given more than 10 units of PRBC within 24 hours and evaluated the relationship between mean PRBC storage duration and in-hospital mortality using multivariable logistic regression...
