Haemo-autologous Antegrade Repriming (HAR) as Minimum Impact Perfusion Strategy for Cardiopulmonary Bypass

"HAR, the 6 steps procedure that results in 300ml of haemodilution. Step 0: Circuit is primed with 1000ml of crystalloid solution. Step 1: Venous line content is drained to the reservoir. Step 2: arterial srystalloid priming is displaced to the reservoir retrogradely by autologous blood. Step 3: Crystalloid priming is discarded to the collector bag. Step 4: An amount of 300ml of arterial blood is sequestered to the reservoir avoiding the mixture. Step 5: The centrifugal pump and the oxygenator are reprimed with autologous blood displacing the priming and GME to the collector bag. Step 6: CPB is initiated with a low haemodilution of 300ml.~Available at: https://zenodo.org/record/4276132#.X7K8AchKgRk"
