Abstract
Sequestration of autoplasma, enriched with platelets by the method of intraoperative thrombocytapheresis
(IOT) using hemoseparator, allows reducing clotting system dysfunction after cardiopulmonary
bypass, perioperative blood loss volume and the demand in hemotransfusion.
IOT performance is possible in two options, which are differed by exfusion method of autoblood
for the following instrumental division. The first is fast and passive sampling into the capacity
with anticoagulant. The second is slow and made by hemoseparator. In the first case, anticoagulation
is relieved but contraindications are increased, such as critical degree of stenosis for mitral
or aortic valves.
We performed IOT to the patient with critical aortic stenosis, using immediate blood sampling.
600 ml of autoplasma with platelets were provided.
