There have been a number of recent reports describing water intoxication in infants.1-4 In each case, hyponatremia followed an excessive intake of free water, either as the result of feeding mismanagement1-3 or vigorous hydration with water during a febrile illness.4 This report describes an infant who developed hyponatremia and seizures after swallowing an unknown volume of water during a swimming lesson. We will discuss the case and comment on present recommendations for preschool swimming instruction.
An 11-month-old girl was in excellent health until the day of admission. During a 60-minute swimming lesson, she was noted to swallow more water than usual, but exhibited no unusual symptomatology while in the pool.
