Laboratory and Clinical Studies during Prolonged Partial Extracorporeal Circulation Using the Bramson Membrane Lung

Abstract

The survival rate, electrolyte changes, hematological changes, arterial gas analysis, and pulmonary compliances in 14 prolonged venovenous perfusions with the Bramson membrane oxygenator are presented. The Bramson membrane oxygenator functioned efficiently. There were two deaths in the series, neither attributable to the perfusion. Arterial gas studies and pulmonary compliance studies indicated no measurable detrimental effect on the lungs. Platelet counts decreased and white blood cell counts increased during perfusion. A clinical prolonged veno-venous perfusion is reported.
