[Intracellular potassium in normal and pathological pregnancy. II. Experimental results].

Intraerythrocyte potassium was determined on samples from 198 physiologic, 88 hypertensive and 92 diabetic pregnant women. An increasing trend was observed during puerperium after the day 3, but a significant difference among the groups was not detected. These results may be due to a wider involvement of other cations (sodium, calcium) in the pathophysiology of pregnancy.
