Abstract
An acute suprarenal occlusion of the aorta was produced in anaesthetized dogs by means of a ballon-tipped catheter. The resultant increase in wedge-pressure led to changes in pulmonary perfusion and raised O2 partial pressure in the arterial blood. The additional, simultaneous occlusion of the left subclavian artery by means of a second balloon-tipped catheter aggravated the haemodynamic manifestations of the pressure-load on the heart; but did not cause a proportionate increase in wedge pressure and O2 partial pressure.
摘要
通过带球囊导管在麻醉犬身上制造急性主动脉肾上腺闭塞。由此导致的楔压升高引起肺灌注改变，并使动脉血中氧分压升高。通过第二个带球囊导管同时额外闭塞左锁骨下动脉，加重了心脏压力负荷的血流动力学表现；但并未导致楔压和氧分压成比例升高。
