A newborn infant became edematous, polyuric, and hyponatremic while being ventilated by a respirator with ultrasonic humidification. Administration of intravenous fluids was drastically decreased without clinical change. Following the discontinuation of the ultrasonic nebulizer, the edema cleared and serum sodium concentration returned to normal. Based on this experience and the knowledge that water is rapidly absorbed from the lungs, we suggest that highoutput ultrasonic nebulizers may be hazardous in the newborn period when combined with assisted ventilation.
