Acute normovolemic hemodilution (ANH) is part of our current protocol to decrease post-operative bleeding and homologous blood transfusions post cardiopulmonary bypass. Blood is drawn from our patients pre-bypass after obtaining the arterial line and administered back to the patient after separation from cardiopulmonary bypass (CPB) and reversal of heparin with protamine. In our practice we noticed some variability in the impact of ANH on postoperative bleeding; with some patients appearing to show more hemostasis after separation from CPB than others. This is a prospective study to find out if there is an optimal time period that guarantees the largest amount of functioning platelets and what is the best practice for drawing and storing of ANH to guarantee the largest amount of functioning platelets.

The investigators primary objective is to determine if acute normovolemic hemodilution (ANH) for pediatric cardiac surgical patients decreases the volume of blood products transfused durin...
Efficacy and safety assessment of of Acute Normovolemic Hemodilution and its influence on blood product usage, hemostatic markers, and amount of chest tube drainage at 24 hours post CABG s...
Several studies have highlighted the cardioprotective effects of acute normovolemic hemodilution during cardiac surgery. The aim of our study is to show that an increase in endogenous eryt...
Impact of acute normovolemic hemodilution (ANH) using hydroxyethyl starch before initiating cardiopulmonary bypass (CPB) on whole blood viscoelastic profile after CPB has not been well est...
The purpose of this study is to learn the best method of assigning patients to receive "acute normovolemic hemodilution" during liver surgery.
The concept of hemodilution after blood loss and crystalloid infusion is a surgical maxim that remains unproven in humans. We sought to quantify the effect of hemodilution after crystalloid administra...
BACKGROUND The aim of this study was to investigate the effects of various ratios of hemodilution on the survival of McFarlane's skin flaps. MATERIAL AND METHODS An experimental study was performed on...
Systemic inflammatory response and hemodilution are prominent factors associated with cardiopulmonary bypass and result in increased morbidity and mortality in children. Miniaturized systems have evol...
A relevant morning-afternoon variation in ischemia-reperfusion (IR) insult after cardiac surgery has been demonstrated. We speculated that the biorhythm might also impact systemic reactions involved i...
Vascular surgery constitutes approximately 6.5% of surgical procedures performed for combat injuries, yet general surgeons are increasingly unfamiliar with vascular surgery. This study examines the fr...
Agents that have a strengthening effect on the heart or that can increase cardiac output. They may be CARDIAC GLYCOSIDES; SYMPATHOMIMETICS; or other drugs. They are used after MYOCARDIAL INFARCT; CARDIAC SURGICAL PROCEDURES; in SHOCK; or in congestive heart failure (HEART FAILURE).
Surgical procedures performed using a computer that remotely controls surgical instruments attached to mechanical arms designed to perform the tasks of the surgeon.
Surgery performed on the heart.
Procedures in which placement of CARDIAC CATHETERS is performed for therapeutic or diagnostic procedures.
Surgical procedures done to prevent or reduce the risk of developing cancer or other disease conditions in persons who may be predisposed to such conditions.
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
