胆道“T”管引流低钾患者功能性细胞外液中电解质水平的探讨

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。

ELECTROLYTES CHANGES OF FUNCTIONAL EXTRACELLULAR FLUID IN HYPOKALEMIC PATIENTS FOLLOWING BILIARY SURGERY

Potassium, sodium, chlorides, calcium, phosphorus and magnesium concentrations ia blood and in 34 hurine, potassium, sodium chlorides and calcium concentrations in bile were determined in 23 patiennts with hypokalemia following biliary operation and a T-tube drainage. The results show that the level of sodium, chlorides, calcium, phosphorus and magnesium concentration in most of hypokalemic patients were within normal range, but sodium, chlor ides, calcium, phosphorus and magnesium in 24 h urine and sodium and calcium in bile in a small part of patients were low. This is due to the relative stability of these electrolytes in the body than the pptasslum and the intra and extracelluar ions exchanges and the regulation in kindney and liver. Among the patients with normal serum sodium and chlorides but low in urine, these would be a potential danger of hyponatremia and hypochlororemia.
