What is the maximum fluid bolus for pediatric hypotension?

The maximum fluid bolus for pediatric hypotension is typically established at 60 mL/kg. This volume is based on current pediatric resuscitation guidelines, which emphasize the need for adequate fluid resuscitation in cases of shock or hypotension in children.

Administering up to 60 mL/kg of isotonic crystalloid solution is intended to restore intravascular volume and improve perfusion. It is important to approach fluid resuscitation carefully in pediatrics due to their smaller blood volume and unique physiological responses compared to adults. The guideline aims to strike a balance between providing enough fluid to correct hypotension without overwhelming the child’s cardiovascular system.

Reasons the other options do not align with current practice include 30 mL/kg, which may be insufficient for more severe cases of hypotension or shock, and the higher volumes of 90 mL/kg and 45 mL/kg, which could potentially lead to fluid overload, especially in younger or smaller pediatric patients. Thus, 60 mL/kg is established as a safe and effective maximum for fluid bolus in pediatric hypotension.
