Extracorporeal membrane oxygenation approached through one vein by using vibrating flow pump

We have reported that the Vibrating Flow Pump (VPP) give the good gas exchange efficiency to the membrane oxygenator, when the VFP was applied as the pump for Extracorporeal circulation (ECC) in animal experiments. In this paper, 6 adult gouts were anesthetized by halothane®. The incision was carried through the fascia of the neck, and left common cervical vein was exposed, via this vein inflow cannula was inserted for right atrium. After that, the transverse skin incision across the breast on the left side of goat, and outflow cannula was inserted main trunk of pulmonary artery. After extracorporeal membrane oxygenator (ECMO) circuit was set, respirator was stopped, several minutes later, ECMO was started using VFP with the driving frequency 20Hz. ECMO blood flow was kept about 10~20 ml/min/Kg, FiO₂: 1.0, O₂: 3 l/min. The effect of ECMO using VFP was evaluated blood gas analysis and hemodynamics. During ECMO, PaO₂ was maintained about 100 ~ 150 torr and PaCO₂: 35~45 torr. No remarkable change was given to the goat by ECMO using VFP. This result shows that the ECMO using vibrating flow pump is very useful for respiratory distress syndrome.
