Abstract

The aim of the study was to evaluate the effects of phosphorylcholine coating (PC) on intra-operative extracorporeal circulation (ECC) management and perioperative outcome. One hundred and twenty consecutive cardiac surgery patients were enrolled for the study. Patients were randomly assigned to ECC with PC circuits (60 patients) or to corresponding non-coated circuits (60 patients). Trans-oxygenator pressure drop, blood flows, flow resistances and ECC parameters were recorded at surgery before ECC institution and every 10 min thereafter until ECC discontinuation. Postoperative variables (hematological parameters, drainage blood loss, mechanical ventilation time, incidence of atrial fibrillation, use of blood products) were also assessed and compared between groups. No differences were found between the two groups in terms of demographics, operative, and hematological profiles. PC showed, at equal pump flows, to significantly (P<0.01) attenuate pressure drop across oxygenators and to reduce oxygenator inlet pressures during ECC. Postoperatively, PC showed to remarkably reduce platelet consumption. Coating showed also to reduce postoperative blood loss, although the difference did not reach statistical significance. No differenc...Continue Reading

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
