What infusion rate is commonly used in initial fluid resuscitation for burn patients?

• A. 20 ml/kg
• B. 5 ml/kg
• C. 50 ml/kg
• D. 100 ml/kg

Answer: (A)

Restoring intravascular volume quickly after a burn is essential to prevent hypoperfusion and organ injury. In practice, isotonic crystalloid like lactated Ringer’s is used, and the Parkland formula guides the total 24-hour fluid need. To begin resuscitation, a common starting approach is a fluid bolus of about 20 mL/kg, which provides rapid volume expansion to improve perfusion while the burn area and TBSA are assessed. After this initial bolus, the Parkland calculation is used to determine the remaining fluid over the next 24 hours, with half of that amount given in the first 8 hours and the rest over the following 16 hours, titrated to urine output and patient response. The 20 mL/kg starting rate is chosen because it offers a safe, effective initial expansion without overshooting, whereas smaller amounts may be insufficient and larger boluses can risk fluid overload.
