Abstract
Introduction: In general, Oxygenators that are used for Percutaneous Cardiopulmonary Support (PCPS) and Extracorporeal menhrane oxygenation (ECMO) are currently used also for open heart surgery. However, the selection of an appropriate oxygenator for POPS is not established. We have been used four type oxygenators so far, Mera/HPO-15H for 15 patients, huraray/Menox AL-4000 for 18 patients, AL-6000 for 18 patients, and Avecor/Ultrox-2 for 6 patients. Methods & Results: The time of cardiopulmonary bypass for each oxygenators were as follows: HPO-15H for mean 5 hours 20 min (29min. -20hours).; A1-4000 for mean 27 hours (82min. -144hours); AL-6000 for mean 31 hours (95min. -186hours); and Ultrox-2 for mean 42.5hours (5hours -117.5hours). Three cases of the oxygenator should be exchanged becouse of in appropriate removal of carhondioxide. Also, there were two cases of blood leakage from the crack of oxygenator, and the thrombus production at the blood outlet port of oxygenator were seen in many cases. Conclusion: Further development of oxygenator for such as POPS, ECMO and for longer use should be encouraged.
