本文采用冷加压试验观察了30例平原健康人(海拔1400m)血液动力学变化,并与同一人群急速进入高原(海拔5170m)健康人22例未作冷加压试验血液动力学进行对比分析。结果:①平原地区冷加压试验血液动力学变化呈高排低阻,与急速进入高原后健康人血液动力学比较无显著差异(P>0.05)。②经跟踪观察本组无一例发生急性高原病。因此,我们认为在平原地区可用冷加压试验检测入高原前的血液动力学变化,心脏储备良好,血液循环呈高排低阻者是高原适应人群。此法可能成为急性高原病的预测手段。
In this paper, we observed the changes of hemodynamics in 30 plain healthy subjects (altitude 1400m) by cold-compression test and compared them with that of 22 healthy subjects who did not make cold stress test at the same altitude (altitude 5170m). Results: (1) There was no significant difference in hemodynamics between cold stress test in plain area and healthy subjects (P> 0.05). ② no follow-up observation of this group of patients with acute plateau disease. Therefore, we believe that in the plain areas can be used cold test before entering the plateau to detect hemodynamic changes, good heart reserve, blood circulation showed a high row of low resistance is the plateau population adaptation. This method may become a means of predicting acute altitude sickness.
