BACKGROUND: Topical tranexamic acid (TXA) was introduced to replace the previous targeted preoperative autologous blood donation (PABD) program. This study aims to analyze the efficacy of topical TXA compared with targeted PABD in anemic patients undergoing primary total hip arthroplasty (THA). METHODS: Two thousand two hundred fifty-one patients underwent primary THA between 2009 and 2013 using targeted autologous blood donation for 280 anemic patients (12%; Hb <12...

BACKGROUND: Various adverse effects of homologous blood transfusion detected particularly in open heart surgery, in which it is frequently used, lead researchers to study on autologous blood use and to evaluate the patient's blood better. Due to the complications of homologous blood transfusion, development of techniques that utilize less transfusion has become inevitable. We aimed to evaluate the effects of acute normovolemic hemodilution (ANH) in patients undergoing open heart surgery...

BACKGROUND: Randomized trials, for example, RECESS, comparing "young" (median, 7-day) versus "middle-aged" (median, 28-day) red blood cells (RBCs), showed no difference in outcome. These data are important; however, they do not inform us about the safety and effectiveness of the oldest RBCs, which some patients receive. It may not be feasible to conduct a clinical trial randomizing patients to receive the oldest blood. Therefore, we propose strenuous exercise (VO2 max testing) as a model to study the relative efficacy to increase oxygen delivery to tissue of different RBC products, for example, extremes of storage duration...

BACKGROUND: Blood conservation strategies have evolved greatly over the last 5 years. There is a paucity of large blood utilization studies of total hip arthroplasty (THA) and total knee arthroplasty (TKA) that include recently performed surgery. The purpose of this study was to use a large database to evaluate trends in blood transfusion after THA and TKA, including 2015 data. METHODS: The Humana data set was reviewed from 2007 to the third quarter of 2015 for all patients undergoing primary THA and TKA...

BACKGROUND: Autologous blood transfusion drainage (ABTD) has been used for many years to reduce blood loss in total knee arthroplasty (TKA). We evaluate the current evidence concerning the efficiency and safety of ABTD used in TKA compared with conventional suction drainage (CSD). METHODS: We performed a systematic literature search of the PubMed, Embase, Cochrane Library and four Chinese databases. All randomized controlled trials (RCTs) that compared the effects of ABTD versus CSD in TKA were included in the meta-analysis...

BACKGROUND: Liver resection is a major surgery with significant mortality and morbidity. Specialists have tested various methods in attempts to limit blood loss, transfusion requirements, and morbidity during elective liver resection. These methods include different approaches (anterior versus conventional approach), use of autologous blood donation, cardiopulmonary interventions such as hypoventilation, low central venous pressure, different methods of parenchymal transection, different methods of management of the raw surface of the liver, different methods of vascular occlusion, and different pharmacological interventions...

Congenital anemias comprise a group of blood disorders characterized by a reduction in the number of peripherally circulating erythrocytes. Various genetic etiologies have been identified that affect diverse aspects of erythroid physiology and broadly fall into two main categories: impaired production or increased destruction of mature erythrocytes. Current therapies are largely focused on symptomatic treatment and are often based on transfusion of donor-derived erythrocytes and management of complications...

Advanced therapy medicinal products (ATMPs) represent the current pinnacle of 'patient-specific medicines' and will change the nature of medicine in the near future. They fall into three categories; somatic cell-therapy products, gene therapy products and cells or tissues for regenerative medicine, which are termed 'tissue engineered' products. The term also incorporates 'combination products' where a human cell or tissue is combined with a medical device. Plainly, many of these new medicines share similarities with conventional haematological stem cell transplant products and donor lymphocyte infusions as well as solid organ grafts and yet ATMPs are regulated as medicines and their development has remained predominantly in academic settings and within specialist centres...

We aimed to evaluate whether blood conservation strategies including intraoperative autologous donation (IAD) could reduce perioperative blood transfusion for patients undergoing cardiac valve replacement including mitral valve replacement, aortic valve replacement (AVR), and double valve replacement (DVR).A total of 726 patients were studied over a 3-year period (2011-2013) after the implementation of IAD and were compared with 919 patients during the previous 36-month period (January 2008-December 2010). The method of small-volume retrograde autologous priming, strict blood transfusion standard together with IAD constituted a progressive blood-saving strategy...

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...

Current sources of platelets for transfusion are insufficient and associated with risk of alloimmunization and blood-borne infection. These limitations could be addressed by the generation of autologous megakaryocytes (MKs) derived in vitro from somatic cells with the ability to engraft and differentiate in vivo. Here, we show that overexpression of a defined set of six transcription factors efficiently converts mouse and human fibroblasts into MK-like progenitors. The transdifferentiated cells are CD41(+), display polylobulated nuclei, have ploidies higher than 4N, form MK colonies, and give rise to platelets in vitro...

Cardiac surgery accounts for between 15% and 20% of all blood product utilization in the United States. A body of literature suggests that patients who are exposed to even small quantities of blood have an increased risk of morbidity and mortality, even after adjusting for pre-operative risk. Despite this body of literature supporting a restrictive blood management strategy, wide variability in transfusion rates exist across institutions. Recent blood management guidelines have shed light on a number of potentially promising blood management strategies, including acute normovolemic hemodilution (ANH) and retrograde autologous priming (RAP)...

BACKGROUND AND OBJECTIVES: A blood transfusion is almost inevitable in neonatal cardiac surgery. This study aimed to assess the feasibility of using autologous cord blood for a cardiopulmonary bypass (CPB) priming as an alternative to an allo-transfusion in neonatal cardiac surgery. SUBJECTS AND METHODS: From January 2012 to December 2014, cord blood had been collected during delivery after informed consent and was stored immediately into a blood bank. Eight neonatal patients had their own cord blood used for CPB priming during cardiac surgery...

AIM: During cesarean section (CS) for placenta previa (PP), the size/area/portion of the lower uterine segment occupied by the placenta may affect the bleeding amount and the subsequent need for a blood transfusion (BT). We propose a new concept, indiscernible edge total PP (IEPP), when vaginal ultrasound does not discern the lower placental edge because the placenta covers the visible lower segment. We characterized IEPP, focusing on its allogeneic BT requirement. METHODS: We classified PP (n = 307) into four types: marginal, partial, discernible edge total PP (DEPP) and IEPP: internal ostium (os)-placental edge distance measurable or unmeasurable on vaginal ultrasound in DEPP or IEPP, respectively...

BACKGROUND: Transfusion of a single unit of stored red blood cells (RBCs) has been hypothesized to induce supra-physiological levels of non-transferrin bound iron (NTBI), which may enhance inflammation and act as a nutrient for bacteria. We investigated the relation between RBC storage time and iron levels in a clinically relevant "two-hit" human transfusion model. STUDY DESIGN AND METHODS: Eighteen healthy male volunteers (ages 18-35 years) were infused with 2 ng lipopolysaccharide (LPS)/kg to induce systemic inflammatory response syndrome...

BACKGROUND: Leukocyte filtration has been hypothesized to reduce the risk of postoperative infections by alleviating the immunosuppressive effect of whole blood. However, the literature regarding the clinical efficacy of leukocyte filtration remains conflicted. This meta-analysis investigates the impact of allogeneic and autologous leukocyte-filtered blood transfusions on the incidence of postoperative infections in adult surgical patients. METHODS: A comprehensive literature search of PubMed, Google Scholar, and Cochrane Central Registry of Controlled trials (1966-2016) was completed for all published randomized controlled trials...

BACKGROUND: Minor red blood cell antibodies are becoming a more common cause of hemolytic disease of the newborn. Anti-U are a rare alloantibody found almost exclusively in people of black descent. There is limited experience to guide the management of pregnancies complicated by anti-U. Furthermore, there is often no suitable cross-matched blood available for transfusion of a patient with anti-U.

BACKGROUND: Pre-donation of autologous blood prior to spine fusion for adolescent idiopathic scoliosis (AIS) has been used in deformity surgery. The effect of pre-donation on pre-operative hematocrit (Hct) remains debated. Multiple factors may influence pre-operative Hct including intravascular volume status, patient factors, and timing of pre-operative blood donation. The purpose of this study was to determine if pre-donation significantly lowers pre-incision Hct in AIS patients. METHODS: A retrospective cohort study of a Level-1 prospective randomized trial was conducted...
