摘要
目的:探讨体外冲击波(ESW)冲击犬心脏对血流动力学的影响。方法:以杂种犬的右室心尖部作为ESW的冲击靶点,右侧股动脉插管监测股动脉血压;采用Swan-Gans导管监测右房压、右室压、肺动脉压;热稀释法测定犬的心输出量。结果:ESW冲击犬心脏后,股动脉收缩压和右室收缩压下降(P<0.05),右室舒张压和肺动脉的收缩压、舒张压和平均压均升高(P<0.05);心输出量无明显改变(P>0.05)。结论:ESW冲击犬心脏可导致血流动力学紊乱。
Objective：To study on effects of extracorporeal shock wave（ESW） on canine hemodynamic.Methods：The dogs of the right ventricular apex as ESW impact target,the right femoral artery to monitor arterial blood pressure;used Swan-Gans catheter to monitor right atrial pressure,right ventricular pressure,pulmonary arterial pressure;thermal dilution method in dogs the cardiac output.Results：ESW impact of dog heart,the femoral artery systolic pressure and right ventricular systolic pressure decreased（P〈0.05）,right ventricular diastolic pressure and pulmonary artery systolic pressure,diastolic and mean pressure were increased（P〈0.05）;cardiac output conclusions did not change significantly（P 0.05）.Conclusion：The ESW impact dog heart may cause the blood dynamics disorder.
