本文报告高海拔地区急性呼吸衰竭患儿37例，在入院24小时内进行甲襞微循环视察，并与正常组进行对比研究。结果表明；甲襞微循环的血管形态、血流状态、襻周状态等多项指标有明显改变，输入枝明显收缩变细，输出枝随缺氧程度加重变宽。血流速度减慢、血流摆动、停滞，红细胞聚集，襻周出血、渗出等改变使微循环正常流态发生紊乱。这些可能是构成儿童急性呼吸衰竭微循环障碍的病理学基础。
In this paper, 37 cases of acute respiratory failure in high altitude area were reported. The microcirculation of formazan was observed within 24 hours after admission and compared with the normal group. The results showed that the morphological changes of blood vessels, blood flow state and perinatal state of nailfold microcirculation were significantly changed. The diameter of the inlet branch shrank conspicuously, and the output branch became wider as the degree of hypoxia increased. Slow blood flow, blood flow, stagnation, erythrocyte aggregation, perineal hemorrhage, exudation and other changes in the normal flow of microcirculation disorders. These may constitute the pathological basis for microcirculatory disturbances of acute respiratory failure in children.
