Catheters were inserted into the aorta and inferior vena cava of newborn lambs by cutdown on the femoral vessels and directly into the umbilical vein. The lambs were killed after six days and the amounts of thrombus surrounding the cathethers were measured. Most catheters inserted into the umbilical vein looped within the liver and only a few passed directly into the portal vein or through the ductus venosus into the vena cava. On different types of catheters inserted via the femoral artery or femoral vein, there were significant differences both in the proportion with thrombus and the amount of thrombus. There were also significant differences in renal infarctions caused by different types of catheters.
通过切开股血管，将导管插入新生羔羊的主动脉和下腔静脉，并直接插入脐静脉。六天后处死羔羊，测量导管周围血栓的量。大多数插入脐静脉的导管在肝脏内盘绕，只有少数直接进入门静脉或通过静脉导管进入腔静脉。对于经股动脉或股静脉插入的不同类型导管，有血栓形成的比例和血栓量均存在显著差异。不同类型导管引起的肾梗死也存在显著差异。
