What is the total fluid requirement for a 2-year-old child as per plan A for dehydration?

The total fluid requirement for a 2-year-old child experiencing mild to moderate dehydration, as outlined in the management protocols for dehydration, comprises both ongoing losses and daily maintenance requirements. According to the World Health Organization (WHO) and the general approach to managing dehydration in pediatric patients, the standard plan for fluid replacement (referred to as Plan A) involves providing an initial fluid bolus based on the child's weight and ongoing losses, typically estimating around 100 mL over the course of several hours for a child of this age.

For a 2-year-old child, the calculation of fluid needs would generally follow a guideline where moderate dehydration could necessitate approximately 10 mL per kg body weight for rehydration and ongoing maintenance fluids. The total of 100 mL aligns with the guidelines focused on addressing mild to moderate dehydration effectively and safely, thus allowing for gradual recovery and stabilization.

Therefore, the choice of 100 mL as an appropriate fluid requirement accurately reflects a standard approach for rehydrating a typical 2-year-old child under circumstances of dehydration as per established protocols.
