Déshydratation hypernatrémique et allaitement maternel

Abstract: Hypernatremic dehydration due to breast-feeding is a rare complication during neonatal period, and can expose neonates to severe sequels. A 7-day-old exclusively breast-fed male, with a birth weight of 2800 g, had suffered from severe dehydration with acute renal failure and metabolic acidosis, with 170 mmol/l of serum sodium and 7,1 mmol/l of serum potassium, rapidly complicated with seizures. Renal and brain ultrasounds were normal. The hypernatremic dehydration was contributed to an excess of sodium intake. The rate of sodium in mother''s milk was three times as high that witness (97 vs 36 mmol/l). Careful intravenous rehydration allowed the correction of hydroelectrolytic disorders and cure without effects. In this observation, the authors present a rare complication of breast-feeding, and severe neonatal dehydration. [Copyright &y& Elsevier]
