目的观察阶梯法、非阶梯法进入特高海拔高原急性高原病(AHAD)发病率。方法经体检健康的内地人员6521名,分为阶梯法进入组(4352名)和非阶梯法进入组(2169名);阶梯法进入组:先乘飞机到达拉萨(海拔3650 m),休息3~4 d后再乘汽车到达海拔4500 m地区;非阶梯法进入组:乘飞机到拉萨后,当天乘汽车进入海拔4500 m地区。统计两组人员于进入高原后1~14 d内AHAD发病率。结果阶梯法进入组AHAD发病率为15.88%(691/4352),非阶梯法进入组发病率为74.96%(1626/2169),组间比较有非常显著性差异(P<0.01)。结论阶梯法可以显著减低进入特高海拔高原AHAD发病率。
Objective To observe the incidence of acute high altitude sickness (AHAD) in step-altitude and non-step-type approaches. Methods A total of 6521 Mainland residents were enrolled in this study. They were divided into three groups (4352) by ladder method and 2169 (non-ladder method) by ladder method. The group entered the group by first flight to Lhasa (3650 m above sea level) 4 d before arriving at 4500 m above sea level by non-staircase method. After arriving at Lhasa by plane, the vehicle enters the area at an elevation of 4500 m on the same day. The incidence of AHAD within 1 ~ 14 days after entering the plateau was calculated. Results The incidence of AHAD was 15.88% (691/4352) in the entry group and 74.96% (1626/2169) in the non-ladder entry group. There was a significant difference between the two groups (P <0.01). Conclusion The ladder method can significantly reduce the incidence of AHAD into the high altitude plateau.
