急进高原4600m健康成人动脉血气和急性轻症高原病评分相关性分析

Correlation between Arterial Blood Gas and Acute High Altitude Response Scores in Healthy Adult Acute exposed to 4600m Altitudes

目的:测定急进高原健康成人动脉血气值和急性轻症高原病评分,通过两者之间的关系的分析,探讨血气变化和急性高原反应之间的关系。方法:对急进到海拔4600m地区145名身体健康的成人进行急性轻症高原病评分和脉搏血氧饱和度的测定,其中48人进行血气检测。结果:急进海拔4600m筑养路工血气分析和急性轻症高原病评分计分之间无明确相关性。而采用急性轻症高原病评分计分与各血气指标进行线性相关分析,同样未发现有明确直线相关关系。对急性轻症高原病评分和脉搏血氧饱和度二者进行了线性相关分析,发现SpO2和急性轻症高原病评分存在线性关系,并得出相关函数关系:SpO2=89.257-0.606×急性轻症高原病评分。结论:急进高原动脉血气分析与急性轻症高原病评分之间未发现有明确相关性;而脉搏血氧饱和度和急性轻症高原病评分之间存在负相关,并得出初步的线性函数关系,为判定急性高原反应和筛选易感人群提供了一项可能的、客观的评估指标,值得今后的进一步研究。

Objective： To study the correlation between arterial blood gas and the acute mild altitude disease scores at high altitude through to measure level of arterial blood gas and record the acute mild altitude disease scores. Methods： 145 healthy adults （roadmen）, who were acute exposed to 4,600m altitudes from 2 260m, were sampled as the subjects in this study. All subjects＇ acute mild altitude disease scores were valuated and blood--oxygen saturation and the blood gas （forty--eight cases） were measured. Resuits： No significant correlation between the level of blood gas and the acute mild altitude disease scores in the roadmen as well the linear correlation analysis. And the correlation between the acute mild altitude disease scores and the sphygmus blood--oxygen saturation showed to have a linear correlation and their func- tion relation can be denoted as follows： SpO2 = 89.257-0.606× the acute mild altitude disease scores. Conclusions： No clear correlation between the blood gas indexes and the acute mild altitude disease scores in roadmen acute exposed to 4 600m altitudes. A negative correlation exists between the sphygmus blood-oxygen saturation and the acute mild altitude disease scores. These results provide a possible method to evaluate the acute mountain response and screen out the hypoxic susceptible persons but further study should be done.
