Membrane lung has been studied for more than ten years in our clinic. Major projects were design of membrane lung and extracorporeal circulation system with membrane lung.
This time, however, effect of extracorporeal circulation on blood and patients was compared between types of artificial lung: membrane lung, bubble oxygenator and disc oxygenator.
Serum LDH, total bilirubin, serum protein and its fraction were studied pre and postoperatively. Postoperative courses were carefully observed.
From postoperative change of these parameters, following considerations were induced. Superiority of membrane lung to bubble oxygenator (Temptrol) was not confirmed by only these parameters. But it is recognized that membrane lung and Temptrol oxygenator are far better than the disc oxygenator.
Our newly designed, automatically controlled bypass circuit with membrane lung was introduced together in this paper.
