Does acute isovolaemic haemodilution affect myocardial function differently at elevated versus normal heart rates in patients undergoing coronary surgery under volatile inhalational anaesthesia?
Acute isovolaemic haemodilution during volatile inhalational anaesthesia for coronary surgery improves stroke volume and decreases systemic vascular resistance without deteriorating cardiac function, even at elevated heart rates.
