A technique was developed to allow percutaneous placement and exchange of pulmonary arterial catheters in conscious dogs. Seven dogs were catheterized weekly for 5 weeks, using a 10-gauge over-the-needle cannula. A No. 7 F flow-directed catheter was passed through the cannula to measure right heart and pulmonary arterial pressures and to calculate cardiac output. The flow-directed catheter was removed and replaced with an arteriographic catheter, and a pulmonary arteriogram was performed. Placement in alternate jugular or saphenous veins each week resulted in successful catheterizations in all dogs evaluated.
开发了一种技术，以允许在清醒犬经皮放置和更换肺动脉导管。使用10号穿刺针套管，每周对7只犬进行插管，持续5周。将一根7F的血流导向导管通过套管插入，以测量右心和肺动脉压力并计算心输出量。移除血流导向导管，换用动脉造影导管，并进行肺动脉造影。每周交替在颈静脉或隐静脉进行插管，使得所有接受评估的犬均成功插管。
