This article reports a case of a cardiac retransplantation without the use of blood products, in a 6 year old, with severe dilated cardiomyopathy after chronic graft rejection and refractory to clinical treatment. To avoid a blood transfusion in this surgery a multidisciplinary approach was planned, which involved the use of preoperative erythropoietin, acute normovolemic hemodilution and intra...

The aim of this study was to test whether oxygenation in acutely ischemic, collateralized tissue may be improved by normovolemic hemodilution with a solution containing liposome-encapsulated human Hb (HbV). A skin flap model in anesthetized hamsters was used, which consisted of two parts receiving either anatomic or collateral perfusion. Microhemodynamics were investigated with intravital micro...

Acute normovolemic hemodilution (ANH) is a blood conservation procedure that can be used in cases of refusal of blood transfusion for religious reasons. Herein, we describe a case of recurarization after reinfusion of collected blood. A combination of rocuronium/sugammadex has the potential to increase the safety of patients if ANH is done after induction. Prospective controlled studies evaluat...

INTRODUCTION The correction of hypovolemia with acellular fluids results in acute normovolemic anemia. Whether the choice of the infusion fluid has an impact on the maintenance of oxygen (O₂) supply during acute normovolemic anemia has not been investigated so far. METHODS Thirty-six anesthetized and mechanically ventilated pigs were hemodiluted to their physiological limit of anemia toleranc...

Large differences in the tolerance of organ systems to conditions of decreased O(2) delivery such as hemodilution exist. The kidney receives approximately 25% of the cardiac output and O(2) delivery is in excess of the oxygen demand under normal circumstances. In a rat model of acute normovolemic hemodilution (ANH), we studied the effect of reduced hematocrit on renal regional and microvascular...

Patients who are Jehovah's Witnesses refuse blood transfusions and blood products as a matter of faith. For surgical procedures during which substantial blood loss is possible, their refusal presents a challenge. 'Anesthetists must generally respect the requests of adults not to receive blood and thus should have a clear understanding of how they will respond in the event of bleeding. Several b...

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 ...

UNLABELLED Low gastric intramucosal pH (pHi) and an increased gastric-arterial PCO2 difference (CO2 gap) are markers of tissue hypoperfusion. Perfluorocarbons (PFCs) have a large oxygen-carrying capacity and release oxygen when encountering low tissue oxygen tension. Nine cardiac surgical patients instrumented for gastric tonometry were enrolled as part of a multicenter, randomized, single-blin...
