Parkland formula monitoring in burn resuscitation.

• A. Blood pressure monitoring alone.
• B. Urine output is used to guide resuscitation and adjust fluids.
• C. Heart rate alone.
• D. Urine output color alone.

Answer: (B)

Urine output serves as a direct indicator of renal perfusion and overall intravascular volume during burn resuscitation. While the Parkland formula estimates fluid needs, actual requirements vary with injury severity and physiologic response, so we titrate fluids to ensure adequate perfusion. A common adult target is about 0.5 mL/kg/hour; if urine output is low, fluids are increased, and if it’s high, fluids are reduced to avoid overload. Blood pressure and heart rate can be misleading early on due to compensatory mechanisms, and urine color alone isn’t reliable. So, monitoring urine output best guides resuscitation decisions.
