本文对23例胆道术后“T”管引流低钾患者同时测定了血、24h尿中钾、钠、氯、钙、磷、镁以及胆汁中钾、钠、氯、钙进行了观察。结果提示低钾患者血钠、氯、钙、磷、镁大多数均在正常范围,而24h尿钠、氯、钙、磷、镁多呈降低,部分患者胆汁钠、钙降低。其原因是这些电解质在体内的分布较钾离子稳定,加之细胞内外离子的交换、肾脏、肝脏的调节。对血钠、氯正常而尿钠、氯降低者,应注意有潜在低钠低氯血症的危险。
In this paper, blood, 24h potassium urinary potassium, sodium, chloride, calcium, phosphorus, magnesium and bile potassium, sodium, chloride and calcium were observed in 23 patients undergoing choledocholithotracheal tube drainage. The results suggest that the majority of patients with hypokalemia serum sodium, chlorine, calcium, phosphorus and magnesium most are in the normal range, and 24h urine sodium, chlorine, calcium, phosphorus and magnesium were decreased, some patients with bile sodium and calcium decreased. The reason is the distribution of these electrolytes in the body more stable potassium ions, combined with intracellular ion exchange, kidney, liver regulation. Right sodium, chlorine normal and natriuresis, chlorine reduction should pay attention to the potential risk of hyponatremia.
