Alloimmunization is a common phenomenon after transfusion, with an estimated incidence of 0.5% increasing to 20-60% in chronically transfused patients. In recently transfused patients, serological typing can be hampered by mixed field agglutination. We established RT-PCR methods for RHD, RHC/c and RHE/e typing using mRNA from reticulocytes. Molecular typing was performed soon after 51 separate ...

BACKGROUND Acute kidney injury (AKI) after cardiac surgery is a major health issue. Two important risk factors for AKI are preoperative anemia and perioperative erythrocyte transfusion, and elucidating their relationship may help in devising preventive strategies. METHODS In this cohort study of 12,388 adults who underwent cardiac surgery with cardiopulmonary bypass and received three units o...

BACKGROUND Cardiac surgery is often complicated by excessive bleeding that is commonly treated with blood products. In the year 2009 a transfusion protocol was introduced specifically designed for cardiac surgery procedures. This study aims to evaluate the effect of this protocol on transfusion of blood products and the occurrence of clinical events. STUDY DESIGN AND METHODS This was a nonran...

Introduction. In the first 48 hours of ventilating patients with acute lung injury (ALI)/acute respiratory distress syndrome (ARDS), a multipronged approach including packed red blood cell (PRBC) transfusion is undertaken to maintain oxygen delivery. Hypothesis. We hypothesized children with ALI/ARDS transfused within 48 hours of initiating mechanical ventilation would have worse outcome. The c...

BACKGROUND Allogeneic red blood cell transfusion is frequently used in total hip replacement surgery (THR). However, data on the prognosis of transfused patients are sparse. In this study we compared the risk of complications following THR in transfused and non-transfused patients. METHODS A population-based follow-up study was performed using data from medical databases in Denmark. We identi...

The purpose of this study has been to evaluate various factors influencing prognosis in children with hemolytic-uremic syndrome (HUS). Forty children with classical picture of HUS were seen in 1986-1 991. Boys and girls were equally affected, aged from two months to ten years. In 35 patients (87.5%) there was a history of diarrhea which was bloody in25. All were treated with peritoneal dial...

Background. The impact of perioperative blood transfusion on the prognosis of gastric adenocarcinoma patients is still controversial. The aim of this study was to elucidate the impact of perioperative blood transfusion on postoperative complications and prognosis of patients who underwent gastrectomy for gastric adenocarcinoma with different levels of preoperative hemoglobin value (POHb). Metho...

BACKGROUND When comparing transfused versus nontransfused patients, erythrocyte transfusion is consistently associated with increased mortality. Nonetheless, unmeasured confounding may unduly influence this comparison. This unmeasured risk may have less influence on comparisons of patients undergoing surgery at hospitals with differing transfusion rates. METHODS Administrative databases were ...
