S-Nitrosylation (SNO) Therapy During Autologous Blood Transfusion

The Purpose of the study is to test the hypothesis that administration of an S-nitrosylating (SNO) agent can improve tissue oxygenation during transfusion of packed red blood cells (RBCs).

Transfusion Surveillance in Anaesthesia

the aim of this register is to collect exhaustively the different data available surrounding a transfusion act in the context of an active haemorrhage. The aim is to allow different modelling and analysis related to emergency transfusion.

Goal-directed vs. Empirical Tranexamic Acid Administrationin Cardiovascular Surgery

The present study is a multi-center randomized prospective placebo-controlled non-inferiority trial. The study's primary objective is to compare the amounts of postoperative bleeding using two different TXA administration strategies: empirical TXA administration vs. viscoelastic test-based goal-directed TXA administration in cardiovascular surgery. The secondary objectives include comparing the incidents of hyper-fibrinolysis, thromboembolic complications, and postoperative seizures. Researchers assumed that goal-directed tranexamic acid (TXA) administration using viscoelastic field tests would not be inferior to the empirical TXA administration strategy in reducing postoperative bleeding and hyper-fibrinolysis. It also would be beneficial in lowering TXA-induced thromboembolic complications and seizures.

Individualized ANH for Non-cardiac Surgery

In this trial, we proposed an individualized acute normovolemic hemodilution (ANH), and conduct a randomized controlled trial to testify the effect of individualized ANH on red cells requirement for non-cardiac surgeries with anticipating major blood loss in adults.

Impact of Transfusional Practice on the Morbidity and Mortality of Patients in Intensive Care Unit

This study will allow correlating transfusion monitoring and patients' prognostic according to the chosen outcome criteria. These data could thus represent a basis for transfusion recommendations, except for intensive care and vital emergencies. It will also bring information about the actual transfusion monitoring in intensive care unit (ICU), in the period following the stay in the ICU and after hospital discharge.

Warmed Blood Transfusion in Premature Infants

Premature babies have to deal with many problems from the moment they are born due to the immature of their organs. Their clinical condition is unstable, especially in the first few weeks, and they are greatly affected by environmental factors. During this period, blood transfusion may be needed for many reasons such as intraventricular hemorrhage and necrotizing enterocolitis. In addition, multiple blood draws to evaluate irregular metabolic, hematological and biochemical findings result in anemia and the need for blood transfusion. There are many algorithms regarding blood transfusion indications and transfusion limits in premature babies. However, there are no strict rules regarding the application of warming before blood transfusion, but it is recommended by some guidelines. Especially in unstable babies such as advanced premature babies, it is recommended to give blood by heating it at physiological temperature to avoid important complications such as hypothermia, coagulopathy and rhythm disturbances. Premature babies, whose hemodynamic and metabolic balance is very sensitive, may go into hypothermia when blood and products stored at +4C⁰ are given without heating. In routine practice, blood transfusion is performed without heating. The concern here is that hemolysis may develop by heating the blood. Studies have shown that hemolysis occurs when blood is heated above 46C⁰. In this study, physiological heating is planned. In vitro neonatal experimental modeling has shown that there is no hemolysis with physiological heating. The aim of the researchers is; While protecting fragile, extremely premature babies from the complications of cold transfusion, the aim is to compare the transfusion groups with and without physiological heating in terms of hemolysis, metabolic balance and cerebral tissue oxygenation.
