Filter by:All patients operated on at the European Hospital Heart surgery Division will be randomized to either single dose 80.000 UI of Human Recombinant Erythropoietin and intravenous iron or control. Primary end point is the amount of transfused blood. Secondary end point is the Hemoglobin level in the patient on postoperative day four. Ancillary analysis regarding safety at 45 days and cost effectiveness are planned as well
Current evidence regarding the efficacy and safety of perioperative administration of tranexamic acid for antifibrinolysis does not suffice to support its use in major spinal surgery. OBJECTIVES: To evaluate the effectiveness of tranexamic acid for decreasing transfusion requirements and bleeding in this patient population. To evaluate the safety of this antifibrinolytic agent in the intraoperative and mid-term postoperative period. METHODS: Multicenter, randomized, double-blind, placebo-controlled clinical trial with parallel groups. The main outcome measure is intraoperative and postoperative transfusion requirements; blood loss and safety will also be evaluated. Previous results in other types of surgery suggest that tranexamic acid reduces transfusion requirements and blood loss. Hence, the hypothesis of this study is that tranexamic acid will significantly reduce blood loss in comparison to a placebo in major spine surgery.
PURPOSE: Autotransfusion devices may be employed in cardiac surgery to decrease allogenic blood requirements. Limitations of previous trials include the use of cell saver systems in selected high risk patients only or the lack of blood transfusion-sparing strategies. The aim of this prospective randomized study is to evaluate the efficacy of cell salvage CardioPAT routinely used in cardiac surgery. METHODS: The investigators will randomize 350 patients in two groups: group 1 receives a CardioPAT cell saver device (175 patients), group 2 doesn't receive any cell saver device. The incidence of allogenic blood transfusion and clinical outcome in both groups are evaluated.
The most effective transfusion practice in critically ill ICU patients is unknown. Currently the data is unclear as to whether a liberal or restrictive transfusion policy is of most benefit to patients in the short and longer term. The aim of this study is to test the hypothesis that liberal use of RBCs (Hb transfusion trigger ≤90g/L; target Hb range 91-110 g/L) to correct anaemia improves clinical outcomes compared with a restrictive transfusion trigger (Hb transfusion trigger ≤70 g/L; target Hb range 71-90 g/L) in anaemic critically ill patients requiring prolonged ICU stay (≥4 days). Patients will be randomised to one of two transfusion strategies on a 1:1 basis Group 1 "Restrictive RBC Transfusion group": Patients will receive single unit RBC transfusions with a transfusion trigger of ≤70 g/L with a target Hb concentration of 71-90 g/L during the intervention period. Group 2 "Liberal RBC transfusion group": Patients will receive single unit RBC transfusions with a transfusion trigger of ≤90 g/L with a target of 91-110 g/L during intervention. These patients will all receive a transfusion on the day of randomisation. Duration of Intervention: Remainder of ICU stay or 14 days from randomisation, whichever is longer Follow-Up Quality of Life, mobility and health service usage questionnaires at 60 and 180 days. This is a feasibility study that will provide essential data to ensure the success of the full trial. A qualitative study will also be carried out to explore potential reasons for non-recruitment and clinician concerns with the existing protocol. An exploratory biomarker sub-study will test whether a pro-inflammatory signal occurs in the liberally transfused group associated with transfusions.
In cardiac operations under cardiopulmonary bypass(CPB), monitoring of brain tissue oxygen saturation with infrared spectrophotoscopy leads to a reduction of the number of packed red cell(PRC) transfusions during the period of extracorporeal circulation.
The primary objective of the study is to compare the immunological status after either autologous blood transfusion as administered by Bellovac® ABT or allogenic blood transfusion, with regards to change in Natural Killer (NK) cell frequency in patients undergoing total knee replacement.
The study is a prospective, controlled, randomised and assessor blind study that investigate if the need for bank blood transfusion could be reduced in patients, undergoing primary or revision total hip replacement surgery, who receive their own blood back with the medical device Sangvia. A comparison in need for bank blood will be made between patients that either receive their own blood back or not.
The purpose of this study is to determine whether length of storage of RBC is related to postoperative morbid outcomes in patients undergoing cardiac surgery.
Individuals who experience a traumatic injury often have a significant amount of blood loss and may require a blood transfusion. In some individuals who receive a blood transfusion, white blood cells from the donor's blood may remain in the body for years, a condition known as microchimerism. This study will examine the reasons why microchimerism occurs in some blood transfusion recipients and not others.
The purpose of this study is to evaluate the safety and effectiveness of epoetin alfa and to determine whether epoetin alfa will facilitate self-donation of blood before surgery in patients who have anemia, (as indicated by low hematocrit levels, the percent of red blood cells in whole blood) and who will be undergoing orthopedic surgery. Epoetin alfa is a genetically engineered protein that stimulates red blood cell production.
