微循环系微动脉与微静脉间的毛细血管循环,是循环系统最基层的结构,甲皱皮肤毛细血管循环的改变,能直接反应末梢循环的状态。高血压病及肺气肿、肺心病时,有全身血液动力学方面的改变,我们通过甲皱微循环的观察,以了解上述疾病对微循环的影响。我科从1976年12月开始,将甲皱微循环检查应用于临床,现将检查甲皱微循环的情况做一小结。 Microcirculation Capillary circulation between the arterioles and venules is the most basic structure of the circulatory system. Changes in the capillary circulation of the nail fold skin can directly reflect the state of peripheral circulation. Hypertension and emphysema, pulmonary heart disease, systemic hemodynamic changes, we observed the nail fold microcirculation to understand the impact of the disease on the microcirculation. Our department from December 1976 onwards, the nail fold microcirculation examination applied to clinical, now check the situation of nail fold microcirculation to make a summary.
