Particulate microemboli and in vitro platelet aggregation were studied in blood of patients during cardiac operations with an electronic particle size analyzer. A small gradient of microemboli developed on passage of blood through a bubble oxygenator but not through a membrane oxygenator. However, with both types of oxygenators, there was a sustained increase in the volume of microemboli in car...

We describe the beneficial effects of an intravenous oxygenator (IVOX) on ventilatory pressure requirement, and also several severe complications related to its use in a young trauma victim developing severe acute respiratory distress syndrome (ARDS). In this patient, adequate systemic oxygenation could not be maintained despite the use of fractional inspired oxygen of 1.0, high level positive ...

Key points The margin of human viability has extended to the extremes gestational age (<24 weeks) when lungs are immature and ventilator-induced lung injury is common. Artificial placenta technology aims extend gestation ex utero in order allow additional time develop prior entering an air-breathing environment. We compared haemodynamics cerebral oxygenation piglets immediate period post-oxygen...

In the Departments of Surgery D and R of the University Hospital of Copenhagen (Rigshospitalet) two pump oxygenators of different types, namely, the Rygg-Kyvsgaard III bubble oxygenator and the mark III screen oxygenator, have during the last two years been used in two parallel series of perfusions. An opportunity has thus been provided for comparing the efficacies of the two oxygenators. Since...

In adult cardiopulmonary bypass surgery, vacuum assisted venous drainage has become a popular technique to augment venous return to the bypass circuit. The application of this technique in neonatal cardiopulmonary bypass surgery could be beneficial to the further miniaturization of neonatal circuitry by coupling radical respositioning of the oxygenator and pump console with decreasing line leng...
