How much fluid should be administered via intraosseous access for pediatric patients?

1. 10ml/kg

2. 20ml/kg

3. 30ml/kg

4. 5ml/kg

The correct answer is: 20ml/kg

The recommended fluid administration via intraosseous access for pediatric patients is typically 20 ml/kg. This volume is essential for rapidly resuscitating a child in a state of shock or dehydration. The intraosseous route is a critical alternative to intravenous access, especially in emergencies where IV access may be challenging or time-consuming. Administering 20 ml/kg of isotonic crystalloid solution, such as normal saline or lactated Ringer’s, can help restore circulation volume quickly, supporting vital organ perfusion and stabilizing the child’s condition. This volume is based on established pediatric resuscitation guidelines and reflects the need for substantial fluid replacement in acute situations to prevent further deterioration of the patient’s hemodynamic status. It is important to note that other quantities, such as 10 ml/kg or 30 ml/kg, may not be appropriate in most situations. These volumes could either under-resuscitate or risk fluid overload, leading to complications such as pulmonary edema, especially in delicate pediatric patients. Therefore, adhering to the recommendation of 20 ml/kg ensures a balance between effective fluid resuscitation and safety.
