Analysis of Health Security for Railway Workers in Plains Working in Highland Environment-Take the Construction of the New Sichuan-Tibet Railway as an Example

摘要

The implementation of the western development strategy and the construction of Sichuan-Tibet and Qinghai-Tibet railways have led to a large increase in the number of workers engaged in railway, highway, bridge, and other projects. Most of these people entered the plateau rapidly and started construction work in a relatively short time 3000 m. Medically, plateau above 3000 meters is called medical plateau, and various unfavorable natural factors such as low pressure and hypoxia at plateau can cause various maladjusted symptoms. The mild ones have headache, dizziness, gastrointestinal discomfort, fatigue and weakness, and difficulty in sleeping. When these symptoms develop to a certain extent, we define them as acute mountain sickness (AMS). Even worse, high altitude pulmonary edema (HAPE) and high altitude cerebral edema (HACE) can occur.
