Severe hypokalemia is a potentially life-threatening disorder and is associated with variable degrees of skeletal muscle weakness, even to the point of paralysis. On rare occasions, diaphragmatic paralysis from hypokalemia can lead to respiratory arrest. There may also be decreased motility of smooth muscle, manifesting with ileus or urinary retention. ⋯ Common causes of hypokalemia include extrarenal potassium losses (vomiting and diarrhea) and renal potassium losses (eg, hyperaldosteronism, renal tubular acidosis, severe hyperglycemia, potassium-depleting diuretics) as well as hypokalemia due to potassium shifts (eg, insulin administration, catecholamine excess, familial periodic hypokalemic paralysis, thyrotoxic hypokalemic paralysis). Although the extent of diuretic misuse in professional bodybuilding is unknown, it may be regarded as substantial. Hence, diuretics must always be considered as a cause of hypokalemic paralysis in bodybuilders.

The primary aim of this study was to evaluate for differences in acuity level and rate of admission on return visit between patients who leave without being seen (LWBS) and those who are initially evaluated by a physician. Our secondary aim was as well as to identify predictors of which LWBS patients will return to the ED with high acuity or require admission. ⋯ Generally, patients who LWBS from a pediatric ED were unlikely to return for ED care, and those who did were unlikely to either be triaged as urgent or require hospital admission. This study showed that urgent acuity during the initial visit and number of previous ED visits were significant predictors of admission on return. Identification of these predictors may allow a targeted intervention to ensure follow-up of patients who meet these criteria after they LWBS from the pediatric ED.
