塔克拉玛干沙漠区石油物探４５０名作业职工，在１９８６～１９９０年间，连续发生９例低钾血症患者。经过对１２７名工人的调查，人均摄钾３４．４ｍｍｏｌ／ｄ、排钾１５０．５ｍｍｏｌ／ｄ，长期大量出汗失钾和摄钾不足造成机体缺钾。采取饮水和烹调投放ＫＣｌ的措施，增加钾的摄入量，维持机体钾代谢平衡，对预防沙漠职工低钾血症的发生，取得了良好效果 In the Taklamakan Desert, 450 geophysical workers were employed in the geophysical prospecting. Nine of the patients with hypokalemia developed continuously between 1986 and 1990. After a survey of 127 workers, the average per capita intake of potassium 34.4mmol / d, row of potassium 150.5mmol / d, a large number of long-term sweating loss of potassium and potassium deficiency caused by potassium deficiency. Take drinking water and cooking put KCl measures to increase the intake of potassium to maintain the balance of potassium metabolism, desert workers to prevent the occurrence of hypokalemia, and achieved good results
