Extracorporeal Circulation
Abstract
We have measured blood concentrations of kynurenines and inflammatory markers in 28 patients undergoing coronary arterial graft surgery and, for comparison, 28 patients undergoing non-bypass thoracic surgery. A battery of cognitive tests was completed before and after the operations. The results sho...

Abstract
The presence of a cytokine storm is recognized as a condition possibly involved in the mechanism for the onset, aggravation and progression of acute encephalitis/encephalopathy. Plasma exchange and slow hemodiafiltration have been used as the means of blood purification to deal with acute encephaliti...

Abstract
We report the case of a 55-year-old patient with a large central Palacos embolism of the right pulmonary artery after corporectomy of the lumbar vertebrae 3 and 4 and reconstruction using autologous pelvic bone. The large Palacos embolism was removed successfully from the right pulmonary artery with...

Abstract
The transient systemic low perfusion that occurs during cardiovascular surgery leads to oxidative stress and the production of free radicals. A systemic increase of various markers of oxidative stress has been shown to occur during cardiopulmonary bypass (CPB). However, these markers have not been a...

Abstract
We reviewed the current strategies to rescue patients with severe hypoxemia. Included in these strategies are high-frequency oscillatory ventilation, airway pressure release ventilation, inhaled vasodilators, and the use of extracorporeal life support. All of these strategies are targeted at improvi...

Abstract
We connected our extracorporeal membrane oxygenation (ECMO) circuit to the patient. To minimize reperfusion injury, immediate cooling, arterial/venous shunting, minimal calcium, and hemodilution strategies were used. Once paCO2/pvCO2 gradients were minimized, we instituted sweep gas and gradually in...

Abstract
A recently completed study quantified the percent of fentanyl or morphine sulfate lost to uncoated polyvinylchloride (PVC) tubing or to one of two hollow fiber oxygenators within the extracorporeal life support (ECLS) circuit. The results demonstrated the majority of drug loss was due to adsorption...

Abstract
We established a porcine model of hypoxemia/acidemia without an underlying disease and further challenged the situation with an extracorporeal circuit (ECC).
Hypoxemia/acidemia were induced (3.5 h) and maintained (3 h) in anesthetized pigs (40 kg) by a stepwise reduction in oxygenation, infusion of...

Abstract
Although serious accidents during extracorporeal circulation are infrequent, potential adverse events with both equipment and operation do still occur and require immediate and well-coordinated responses. Hence, perfusionists need to be well trained in both standard and emergency procedures, and thi...

Abstract
The TEG (kaolin) sample was not interpretable due to the heparin effect in 89 (52%) samples. There was a weak correlation between TEG (heparinase) variables and APTT, and between TEG and ACT with a stronger correlation between TEG (Maximum amplitude) and platelet count. CONCLUSION: TEG monitoring sh...
