Outline of Research at the Start |
本研究は「人工肺と血液ポンプを用いた体外循環回路による治療」(Extracorporeal Membrane Oxygenation:ECMO)における拍動流補助循環法による重症呼吸不全の肺機能改善効果を明らかにする。 具体的には、以下の研究を実施する。 1) In-Vitro試験にて肺血管抵抗変化を模擬したオーバーフロー式模擬循環回路にて血液粘性実験を実施し、拍動流ECMOが生体を模擬した肺血管抵抗変化にも対応できることを圧―流量曲線を描いて証明する。 2)重症呼吸不全モデルの小動物実験において、拍動流ECMOと定常流ECMOの比較を実施し、拍動流ECMOの肺機能改善効果について証明する。

Outline of Final Research Achievements |
The golden standard of veno-venous ECMO with continuous flow for Acute Respiratory Distress Syndrome. This study aimed to investigate the impact of the right ventricle on pulmonary artery extracorporeal membrane oxygenation (RV-PA ECMO) for acute respiratory dysfunction with/ or without pulsatile flow during the RV-PA ECMO. We used the bronchoalveolar lavage procedure with intrapulmonary administration of warm saline to establish a severe acute respiratory distress syndrome model. The observation of pneumocytes clearly showed less pulmonary edema, pulmonary fibrosis, and inflammation after the RV-PA ECMO treatment. The concentration of IL-6 was less in the pulsatile group than in the non-pulsatile group. Our study demonstrated that the pulsatile RV-PA ECMO was less vasoconstrictive and supplied more effective oxygenated pulmonary flow than the non-pulsatile RV-PA ECMO. The pulsatile RV-PA ECMO ameliorates pulmonary circulation and facilitate recovery from acute respiratory failure.

Academic Significance and Societal Importance of the Research Achievements |
本研究結果より、RV-PA ECMOを導入することで従来からあるV-V ECMO(右心房脱血・送血)よりも高効率的に酸素加血を傷害肺へ送ることができる。さらに、拍動流を付加させたRV-PA ECMOを用いることで右心室の過負荷を軽減でき、拍動による肺動脈血管内皮及び肺の毛細血管への刺激によって、肺の炎症を抑制できるだけでなく肺血管抵抗を減少させ、肺血流の増加を得ることができることが判明した。このことから、本研究にある拍動流 RV-PA ECMOは重症呼吸不全の肺機能改善効果が明らかになり、重症呼吸不全に対する治療効果と生存退院向上に寄与することが期待される。
