部队经过阶梯适应性训练后急性高原反应发生情况调查

AN INVESTIGATION OF ACUTE HIGHLAND RESPONSE IN GROUPS DOING ASCENDING ADAPTAION

本文对某部４８２人自平原（海拔１４００ｍ）进驻海拔３７００ｍ，经过４０天的阶梯适应性训练，然后快速（４小时）进驻海拔５２７０ｍ，第１～７天急性高原反应的发生率最高为３２．４％，且无１例重症急性高原反应，另一支部队自平原快速（５天）进驻海拔５０１０、５２００和５３８０ｍ，第１～１０天急性高原反应的发生率是高为８５．７％，其中重症急性高原反应为３２．８％，２人发生了高原脑水肿合并高原肺水肿。作者认为进驻海拔５０００ｍ以上地区的部队，应在３７００ｍ左右进行一个月的阶梯适应性训练，可使急性高原病的发生率显著降低。

n investigation was conducted in 482 armymen who ascended from 400m plain ti 3 700m ,af-ter 40d ays adaptation there ascended to 5 270m altitude within 4hours. Results showed that the acutehighland response(AHR)during the 1st to 7th days at 5 270m was 32.4%with no serious cases. An-other investigation was performed in armymen who ascended directly from plain to 5 010m, 5 200mand 5 380m altitude respectively,within 5 days. The rate of AHRwas up to 85.7%during the lst to10th days at altitude,the serious cases were 32.8%of the total and two cases had high altitude cere-bral edema and pulmonary edema,The,results suggested that subjects ascending to high altitude(above5000m)should have ascending adaptation at 3 700m for one month in order to decrease the incidenceof AHR significantly.
