Summary

We related normalized diurnal weight gain (NDWG) to a decrease in serum sodium concentration (DSOD) among 8 schizophrenics subject to water intoxication. DSOD = 0.422 + 1.675 × NDWG (n = 8, r = 0.864, P = 0.006). We used this relationship to interdict drinking and, thus, prevent severe hyponatremia.

Résumé

Résumé

La relation entre l'augmentation diurne du poids et la concentration sérique de sodium a été étudié chez 8 schizophrènes présentant l'intoxication à l'eau. Le poids et le sodium sérique ont été mesurés à 7 heures et 16 heures toutes les semaines pendant 8 semaines. Une excellente corrélation a été trouvée entre l'augmentation diurne du poids (exprimé en pourcentage de l'augmentation diurne) et la baisse diurne de taux sérique de sodium: △ sodium = 0,422 + 1,675 × △ % du poids, (n = 8, r = 0,864, P = 0,006).
