To the Editor.—
I read with interest and some nostalgia the CASE REPORT by Dorin and Crapo1 on hypokalemic respiratory arrest during treatment of diabetic ketoacidosis. It shows why clinicians in the 1940s2,3 advised giving potassium in diabetic ketoacidosis—a routine intervention ever since. Historically, it may be interesting for your readers to know that it was in THE JOURNAL that Holler2 40 years ago published a nearly identical case. He was the first, to my knowledge, to draw attention to this cause of respiratory paralysis and its treatment.
