Abstract Importance  Acute normovolemic hemodilution (ANH) is a well-known blood conservation technique, yet its adoption in the US remains low (<20%), and cardiac surgery remains the largest consumer of blood components...

Abstract Background Patients undergoing cardiac surgery often receive red-cell transfusions, along with the associated risks and costs. Early intraoperative normovolemic hemodilution (i.e., acute normovolemic hemodilution [ANH]) is a blood-conservation technique..

Introduction Cardiopulmonary bypass (CPB) introduces significant alterations in blood composition due to the priming solution, fluid shifts, and extracorporeal circulation. Hemodilution and hemoconcentration represent two opposing strategies, each with distinct..

Abstract Background Minimizing the use of blood component can reduce known and unknown  risks, preserve blood bank resources, and decrease healthcare costs. Red Blood Cell (RBC) transfusion is common after cardiac..

Abstract Autologous blood transfusion can be achieved through different techniques, including by the patient donating blood before surgery (pre-deposit), collecting blood from the patient immediately before the operation and replacing..

Abstract Objectives Patients undergoing cardiac surgery often require , which are associated with increased morbidity and mortality. Patient blood management (PBM) strategies, including acute normovolemic  (ANH), have been implemented to minimize allogeneic..

Abstract Background The use of crystalloid priming for extracorporeal circuit in adult cardiac surgery causes inevitable haemodilution. The haemodilution can be reduced by using methods such as retrograde autologous priming..

Abstract Study Objective: To investigate whether large volume acute normovolemic  (L-ANH), compared with moderate acute normovolemic  (M-ANH), can reduce perioperative allogeneic   with intermediate-high risk of transfusion during cardiac surgery with  (CPB). Design: Prospective . Setting:..

Abstract Background The adverse effects of cardiopulmonary bypass during open cardiac surgery, including hemodilution, seem to be inevitable, especially for patients who generally have a relatively lower BMI with relatively..

Abstract Objective: The study aimed to evaluate the effect of mild and moderate hemodilution during CPB on the neurocognitive dysfunction in patients undergoing coronary artery bypass grafting.  Design: A randomized clinical study. ..

Abstract Background: During the last decades many efforts have been made to reduce transfusion requirements and adverse clinical effects during cardiopulmonary bypass (CPB). The minimal extracorporeal circulation (MECC) system and the..

Abstract Background:  Although conventional cardiopulmonary bypass (cCPB) is still the most widely used method in open heart surgery, methods such as retrograde autologous priming (RAP) are increasingly popular in terms..

Abstract Objective: Compare the use of blood products and intravenous fluid management in patients scheduled for coronary artery bypass surgery and randomized to minimal invasive extracorporeal circulation (MiECC) and conventional..

Abstract The American Society for Testing and Materials (ASTM) F1841 standard for the assessment of hemolysis in blood pumps recommends using phosphate-buffered saline (PBS) for hemodilution to standardize hematocrit (HCT)...

Abstract UNLABELLED:Hemodilution during cardiopulmonary bypass (CPB) is a primary risk factor for blood transfusion in cardiac surgical patients. Priming of the CPB circuit with the patients' own blood (retrograde autologous..

Abstract The current practice of cardiopulmonary bypass (CPB) requires a preoperative priming of the circuit that is frequently performed with crystalloid solutions. Crystalloid priming avoids massive embolism but is unable..

The learner will be able to discuss the pros and cons of blood transfusions and the morbidities associated with transfusion and the morbidities associated with excessive hemodilution.

Abstract Background:  Coronary artery bypass surgery is the most commonly performed cardiac operation and approximately 40-70% of patients require a blood transfusion despite improvements in cardiac surgical techniques. Some preventive..

Abstract Background: We designed a non-invasive, observational, real-time study, using near-infrared spectroscopy (NIRS) to assess the in vivo effects of cardiopulmonary bypass (CPB) on patients’ skeletal muscle as well as..

Abstract The desired use of the HPH Jr. is optimal due to the low priming volume; however, the lower rate of volume removal necessitates utilization of a larger hemofilter. Larger..

Abstract Background:  Retrograde autologous priming (RAP) before cardiopulmonary bypass (CPB) may minimize allogeneic red cell transfusion. We conducted a systematic review of the literature to examine the impact of RAP..
