Abstract:
Objective By analyzing the clinical symptoms, heart rate ( HR) , arterial oxygen saturation ( SaO2 ) and the number of white blood cells (WBC), we aimed to explore the implication of the above-mentioned indexes for early warning of high altitude pulmonary edema ( HAPE) .Methods Based on the Lake Louise Self-assessmeat Scoring System ( LLSS) and the scoring of respiratory symptoms, 628 subjects were divided into three groups: group A ( the healthy;score<3),group B(acute mountain sickness, AMS; score>3 and excluding HAPE),and group C (HAPE).Moreover, we analyzed the incidence of some clinical symptoms, HR and SaO2 , as well as the WBC number of some subjects in the three groups.Results The incidence of respiratory symptoms and WBC number were significantly increased in group C compared with group B(P<0.05).In addition,unlike group A and B, the mean HR in group C rose gradually in the first 3 days and was markedly increased at the third day(F=6.37,P<0.05).The mean SaO2in group C was remarkably lower than in group A and B in the first 3 days(F=8.21,F=8.77,F=9.58,P<0.01).Conclusion Those who enter high altitude for the first time with notable respiratory symptoms, WBC increase, HR maladaptation and decrease in SaO2 (>30%) have high risk of HAPE.It is of special importance to detect HAPE earlier at high altitude.
