A simple heparin-bonded circuit to facilitate a femoral vein to femoral artery shunt for the treatment of right-sided circulatory failure is proposed. Desaturated venous blood is shunted to the left-sided circulation to increase systemic blood pressure at the expense of saturation. The circuit comprised 1/4 inch x 3/32 inch tubing with a paediatric Bio-Medicus centrifugal pump head allowing adequate regulation of flow. Paediatric Bio-Medicus cannulae provide flows between 500 and 2000 ml/min. Measurements of pulmonary artery pressure, central venous pressure, arterial pressure, arterial saturation and cardiac output were recorded. In the four case studies presented, the treatment included unloading of the right ventricle with venous to arterial shunting. Likewise, eight Holstein calves underwent shunt utilization after placement of a left ventricular assist device and induction of right ventricular failure. The future use of this device may be instrumental in aiding the cardiothoracic surgical team in the treatment of right-sided circulatory failure.
本文提出了一种简单的肝素化回路，以促进股静脉至股动脉分流，用于治疗右侧循环衰竭。未饱和的静脉血被分流至左侧循环，以牺牲饱和度为代价提高体循环血压。该回路由1/4英寸×3/32英寸的管道和一个儿科Bio-Medicus离心泵头组成，可对流量进行充分调节。儿科Bio-Medicus插管的流量为500至2000毫升/分钟。记录了肺动脉压、中心静脉压、动脉压、动脉饱和度和心输出量。在呈现的四个病例研究中，治疗包括通过静脉至动脉分流减轻右心室负荷。同样，八只荷斯坦小牛在植入左心室辅助装置并诱发右心室衰竭后进行了分流利用。该装置的未来应用可能有助于心胸外科团队治疗右侧循环衰竭。
