New membrane oxygenator (LPM 50): influence on extravascular lung water and pulmonary function in comparison to bubble oxygenator
J Boldt, B von Bormann, D Kling, K Ratthey, J Mulch and G Hempelmann
A prospective, randomized, clinical study involving 30 patients undergoing
aorta-coronary bypass grafting was designed to compare the influence of a
new membrane oxygenator and a commonly used bubble oxygenator on
extravascular lung water and pulmonary function after extracorporeal
circulation. Although membrane oxygenators might have some advantages from
the biochemical and biophysical points of view, in this clinical study no
differences in lung water accumulation and pulmonary gas exchange could be
detected between bubble and membrane oxygenators after extracorporeal
circulation.
