Feasibility of emergency blood collection among people after acute exposure to high altitude / 军事医学

ABSTRACT

Objective To investigate the incidence of altitude reaction among people who rapidly ascend to highaltitude and the health status of experimental emergency blood donors after ascending to high -altitude areas above 4600meters.Methods The vital signs of 185 subjects were analyzed according to GJB1098-1991 and questionaires were filledout.Then the incidence of altitude reaction in different -altitude areas and the change in health status before and after blooddonation at high-altitude were evaluated.Results There was no significant difference in the incidence of altitude reactionin areas of different altitude.However, the incidence of moderate and severe altitude stress increased significantly .Thesimilar altitude reaction incidence despire different means of transportation (74.40% by railway and 70.00% by air) suggestedthat the mode of transportation had little effect.And our results showed good health status among emergency blood donorsbefore and after donation.Conclusion Emergency blood collection is feasible at high altitude (more than 4600 meter high).
