海拔5000米高原急性高山病的发病率及影响因素和伴随症状

THE INCIDENCE IMPACT FACTORS AND ACCOMPANING SYMPTOMS OF ACUTE MOUNTAIN SICKNESS AT 5000m ALTITUDE

本文对进入海拔5000m高原的62例健康人的急性高山病(AMS)的发病率,影响因素及伴随症状进行了现场调查.总AMS发病率为48.4%,发生高原肺水肿1例(1.6%),上山后4天出现外周水肿18例(29%),一周后水肿逐渐消退.72%水肿患者同时合并AMS,提示外周水肿可能和AMS有某种内在联系.年龄及原居住地海拔高度与AMS发病率无明显关系.有居住3500m以上高原史组AMS发病率明显低于无居住高原史组.本文还对AMS一系列伴随症状进行了讨论.

The incidence,impact factors and accompaning symptoms of acute mountain sickness (AMS) in 62 healthy men who sojourned to 5000m high altitude were investigated.The total incidence of AMS was 48.4%.There was only one person (1.6%) suffered from high altitude pulmonary edema (HAPE).Both AMS and HAPE incidences were lower than that in the previous reports with similar altitude.We thought that the cause may be due to slow rate of ascent.18 persons (29%) appeared facial edema within 4 days after reaching destination,but it disappeared gradually after a week.72% of cases with facial edema were complicated by AMS.There was no difference in AMS incidence between two different age groups and two different residential height groups.There was a significant difference in AMS incidence between the two groups with and without pievious altitude experience.A series of symptoms appeared at altutide were also discussed in the study.
