In pediatric hypovolemia, the first move is to rapidly restore intravascular volume with an isotonic crystalloid. The recommended initial bolus is 20 mL per kilogram of body weight, using normal saline or lactated Ringer’s. This amount provides a quick and effective increase in circulating volume to improve perfusion without overloading a fragile pediatric system. Give it quickly (usually over 5–10 minutes) and then reassess perfusion, mental status, urine output, and vital signs. If there’s still poor perfusion after the first bolus, repeat another 20 mL/kg bolus up to a total of about 60 mL/kg in the first hour, while watching closely for signs of fluid overload. Avoid hypotonic or dextrose-containing fluids as the initial resuscitation fluid because they don’t reliably support intravascular volume and can worsen electrolyte balance.
