Introduction: In the prehospital setting, crystalloid fluids are frequently used, but only erythrocytes are capable of transporting oxygen to tissues. The aim of this study was to establish the efficacy and safety of the prehospital use of uncross matched type O rhesus-negative packed red blood cells (URBC) by the Dutch physician-staffed helicopter emergency medical service. We hypothesized that prehospital URBC transfusions are safe and more effective with respect to survival than resuscitations with crystalloids.
Methods: The effects of prehospital URBC transfusions were studied by comparing a cohort of patients (>18 years) who were treated with a combination of URBC and crystalloid fluids with a matched control group of patients who received crystalloid fluids alone.
Results: Among 73 adults who received prehospital URBC transfusions, 50 (68%) patients were included. No transfusion reactions were observed. No effect of prehospital transfusion on 24-h or 30-day survival was found. Haemoglobin levels at presentation to the emergency department were higher in the URBC cohort. The two groups had similar cumulative erythrocyte requirements within the first 24 h.
Conclusion: Neither survival benefits nor a decreased incidence of shock on admission were observed after prehospital helicopter emergency medical service URBC transfusions. There were no prehospital transfusion reactions in this study; therefore, URBC transfusions were deemed to be safe. A prospective randomized study is warranted to evaluate the effect of early URBC transfusions and transfusions with preheated URBC on the survival of patients with severe prehospital haemorrhagic shock.

Background And Objectives: Umbilical cord blood (UCB) has been used as a source of red blood cells (RBCs) for neonatal/paediatric transfusion purposes. This study adopted two different procedures to obtain umbilical RBC (U-RBC) to compare its quality control parameters to those of fractionated adult RBC (A-RBC), for paediatric purposes.
Materials And Methods: UCB units (24) were filtered and processed based on two different methods, namely, conventional/manual (P1;n12) and automatic (P2;n12).

In malaria, rosetting is described as a phenomenon where an infected erythrocyte (IRBC) is attached to uninfected erythrocytes (URBC). In some studies, rosetting has been associated with malaria pathogenesis. Here, we have identified a new type of rosetting.

Background: Cardiac iron overload following liver transplantation in patients without hemochromatosis but with severe hepatic iron deposition has been reported to result in heart failure and/or death in case reports and small case series. However, the frequency and causes of cardiac iron overload following liver transplantation and its relationship to cardiac dysfunction in patients without severe hepatic iron deposition are unclear.
Methods: The primary inclusion criteria for this study were liver transplantation followed by autopsy or cardiac transplantation within 1 year.

Introduction: The use of cell saver (CS) in cardiac surgery is proposed to reduce the use of units of packed red blood cells stored (URBC), which increases morbidity, mortality and causes inflammatory reactions.
Objective: The objective is to evaluate whether the use of CS decreases the use URBC, is cost /effective and beneficial to the patient.
Methods: In a prospective study, between November 2009 and October 2011, 100 consecutive patients who underwent cardiovascular surgery with CPB, hemodilution and hemofiltration, were enrolled.
