[Therapeutic guides in hypertonic dehydration (author's transl)].

Physiopathology of hypertonic dehydration is revised. The bases of treatment are discussed; they are based on: 1. Basal requirements of fluids. 2. Slow correction of deficit. 3. Replacement of maintaining losses. Total fluids support will carry to rehydration in 2 or 3 days. In the most severe cases peritoneal dialysis is associated. The indications, technique and realization of peritoneal dialysis during hypertonic dehydration are discussed.
