Patient's question:
Acute watery diarrhea for four daysDoctor's answer:
Analysis of the condition: Dehydration in children is caused by insufficient fluid intake or excessive fluid loss, leading to a reduction in total body fluid volume. When the loss reaches 5% or more of body weight, it is considered dehydration. When diagnosing dehydration, it is important to distinguish its severity and nature to provide appropriate treatment.Advice: Treatment depends on the nature of dehydration.
① In hypotonic dehydration, the loss of sodium in the body is relatively greater than the loss of water, with serum sodium < 130 mmol/L and plasma osmolality < 280 mOsm/L, leading to hyponatremia. It is highly prone to shock and cerebral edema. During treatment, 2/3 isotonic fluids should be used, with the preparation method based on volume ratio: physiological saline : 5% glucose solution = 2:1. Alternatively, physiological saline : 5% glucose : 1.4% sodium bicarbonate = 4:3:2.
