目的:分析平原地区、西宁地区人群急进玉树地区后血氧饱和度(SaO2)变化。方法:应用便携式氧饱和度检测仪,检测两地区人群进入玉树地区12小时、24小时、72小时、7天的SaO2并进行分析,了解SaO2变化与发生急性高原病(AHAD)的相关性。结果:平原地区人群SaO2为(85.7±1.6)%时易发生AHAD,发生率为25%。西宁地区人群SaO2为(83.7±2.1)%时易发生AHAD,发生率为21%。结论:SaO2检测可作为筛选AHAD的一个生物学指标。平原地区人群急进玉树地区(3 750m)SaO2较海平面下降11%、西宁地区人群SaO2下降13%,可作为预测发生AHAD指标。
Objective: To analyze the change of postoperative oxygen saturation (SaO2) in the Yushu area of the plain and Xining areas. Methods: A portable oxygen saturation detector was used to detect SaO2 at 12hours, 24hours, 72hours and 7days after entering the Yushu area, and to analyze the correlation between SaO2 changes and the occurrence of acute altitude sickness (AHAD). Results: AHAD occurred in 85% ± 1.6% of the plain area population, with a prevalence of 25%. AHAD in Xining population was (83.7 ± 2.1)%, with a prevalence of 21%. Conclusion: SaO2 assay can be used as a biological indicator to screen AHAD. In the plain areas, SaO2 in the Yushu area (3 750m) dropped by 11% compared with the sea level and SaO2 in the Xining area decreased by 13%, which could be used as a predictive AHAD indicator.
