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 investigate the incidence of acute high altitude disease(AHAD)of people into 4500 m plateau by ladder method and non-ladder method. Methods Total 6521 healthy people to enter Tibet from the plain were divided into the ladder group(n=4352)and non-ladder group(n=2169). After arriving in Lhasa(3650 m above sea level)by plane,the ladder group had a 3-4 d rest and reached an area(4500 m above sea level)by car;after arriving in Lhasa by plane,the non-ladder group did not had a rest but reached to the area(4500 m above sea level)by car on the same day. The statistics of incidence of AHAD of both groups within 1-14 days after they arrived in the high altitude was made. Resuits The incidence of AHAD in the ladder group was 15. 88%(691/4352),while that in the non-ladder group was 74. 96%(1626/2169). There was a significant difference between the two groups (p<0. 01). Conciusion The ladder method can significantly reduce the incidence of AHAD.
