The pediatric dose for Sodium Bicarbonate is established at 1 mEq/kg slow push IV. This dosage is rooted in clinical guidelines that dictate the use of Sodium Bicarbonate primarily in cases of metabolic acidosis, hyperkalemia, or specific toxicological emergencies.

Administering Sodium Bicarbonate at this dose helps effectively correct metabolic acidosis by raising the serum bicarbonate levels, which in turn can stabilize the patient's hemodynamic status and improve cardiac function. The slow push administration is especially crucial in pediatric patients to minimize the risk of rapid changes in serum pH, which can be detrimental.

Using a higher dose, such as 2 mEq/kg, could lead to complications such as alkalosis or fluid overload. Conversely, administering a lower dose, like 0.5 mEq/kg, may not sufficiently correct the acidosis in critically ill children. Fast push IV administration is also contraindicated in this scenario, as it poses additional risks of rapid shifts in bicarbonate levels that could be harmful. Therefore, the 1 mEq/kg slow push is considered the most effective and safe dosage for pediatric patients.
