Reduce Postoperative Bleeding After Cardiopulmonary Bypass Surgery
Background Patients on cardiopulmonary bypass (CPB) have an increased susceptibility to postoperative bleeding. Previous reports using desmopressin acetate (DDAVP) for the prevention of postoperative bleeding have given contradictory results, whereas the protease inhibitor aprotinin has been shown to reduce blood loss after this type of surgery. This randomized study was performed to assess the...
متن کاملSystemic microvascular shunting through hyperdynamic capillaries after acute physiological disturbances following cardiopulmonary bypass.
Previously we showed that cardiopulmonary bypass (CPB) during cardiac surgery is associated with reduced sublingual microcirculatory perfusion and oxygenation. It has been suggested that impaired microcirculatory perfusion may be paralleled by increased heterogeneity of flow in the microvascular bed, possibly leading to arteriovenous shunting. Here we investigated our hypothesis that acute hemo...
متن کاملSeizures Following Cardiopulmonary Bypass.
Seizures following cardiopulmonary bypass are an immediate and alarming indication that a neurologic event has occurred. A case report of a 67-year-old man undergoing aortic valve surgery who unexpectedly experiences seizures following cardiopulmonary bypass is outlined. Possible contributing factors including atheromatous disease in the aorta, low cerebral perfusion pressures, an open-chamber ...

متن کاملPost cardiopulmonary bypass bleeding: an introductory review.
Cardiac surgery requiring cardiopulmonary bypass (CPB) has increased in both number and safety over the past four decades. Postoperative bleeding continues to be a major cause of perioperative morbidity. The reported incidence varies from 4-32%. This paper reviews the preoperative evaluation and specific hemostasis defects associated with cardiac surgery and extracorporeal circulation. Monitori...
