西藏老年性白内障患者的血气分析

Investigation of Blood-gas Analysis in the Senile Patients with Cataract in Tibet

对30名西藏老年性白内障患者进行了血气分析,发现患者血液pH值比当地正常人并酸,血氧饱和度及血氧容量低于正常,86%的患者血液为代谢性酸中毒.结果显示白内障患者的血液携氧功能下降,机体缺氧比西藏正常人更明显,酸碱代谢失衡,表明高山缺氧可能与西藏白内障高发及发病年龄提前有关.

Blood-gas analysis of 30 patients with senile cataract in Tibet was carried out. It was found that blood pH. O2 Sat and O2-CT in these patients were lower than that of the normal human. 86.7% of the patients suffered from metabolic acidosis. The results showed that the function of the blood to transfer oxygen was reduced and acid-base equilibrium was abnormal. It was suggested that high altitude anoxia way have some relationship with the high incidence of cataract and the age of the onset of cataract became younger.
