    We developed a new silicone hollow fiber membrane oxygenator (SHMO) for long term extracorporeal membrane oxygenator (ECMO). SHMO was compared with another type, a silicone coil membrane oxygenator (MMO-6) with regard to blood damage during 24 hours veno-arterial bypass in dogs. The following results were obtained. (1) Scanning electron microscopy showed that membrane surface of MMO-6 after perfusion was covered with platelete aggregates, fibrin nets, red cells, and white cells, but the surface of SHMO was not covered with any blood components. (2) Plasma hemoglobin was increased at the rate of 7.5mg/dl/hr in MMO-6 group, but in SHMO group maximum value was 45mg/dl. Scanning electron microscopy of red cells revealed less morphological change in SHMO group. (3) Platelet counts and ultrastructure by transmission electron microscopy were much preserved in SHMO group. These findings reveal that SHMO is the excellent membrane oxygenator for long term ECMO.

    Extracorporeal membrane oxygenation with microporous polypropylene hollow fiber lung and pumpless arteriovenous method was used in two patients, for 20 hours in a neonate with congenital heart defect and 11 days in a 31 years old female with interstitial pneumonitis and suspect of Pneumocystis carinii pneumonia. Umbilcal and femoral vessels were used respectively. Partial support by a pump was required in the neonate patient. Both patients showed improvements in blood gas data and clinical condition, but did not survive mainly from irreversible lung.

    During the last 2 years, ECMO (V-A bypass with membrane oxygenation) was used in combination with IABP in 7 patients for profound cardiogenic shock following open heart surgery. Hemodynanic improvement for some time was seen in all cases. Three out of 7 patients were able to be weaned from ECMO, and one of them were able to be discharged from hospital in good condition. (One patient who was able to come off ECMO on the 8-th postoperative day, died of hepatic failure one week thereafter.) Although many unresolved problems still remain, combined use of ECMO with IABP is recommendable as the practical circulatory assist for rescuing the patient with profound cardiogenic shock following open heart surgery.

    Application criteria as well as the definition of ECMO are not yet established in Japan. A consideration was given on the points, analizing the complications and problems of our 11 ECMO cases. A case with IABP neccessiate us to re-evaluate ECMO not only as a respiratory assist but as a cardiopulmonary assist maneuver also. It was proposed there are exact differences between the way of ECMO for respiratory and circulatory assist, and the most effectiveness of ECMO with IABP was proved for failing heart and lung clinically as well as experimentally.
