TMO膜型人工肺の臨床使用経験

抄録

In spite of many theoretical advantages, membrane oxygenators had not been used for routine open heart surgery until recently because of high cost, low efficiency and preparation difficulties. But recently, an improved pump-oxy-genator system provided with an inexpensive, disposable and high efficient membrane oxygenator using a microporous polypropylene membrane (TMO) has become available.
This paper describes 25 open heart surgical proceidures using this system. Blood gas studies and analysis of platelet counts were generally satisfactory. Especially, the ability to control oxygen and carbon dioxide transfer separately was proved to be advantageous to maintain the more physiological status during perfusion. But the advantage of low hemolysis was not observed mainly because of the effect of coronary suction.
