Kuinka laskea Parkland Burn Formula

Mikä on Parkland Burn Formula?

The Parkland formula guides IV fluid resuscitation for burn patients in the first 24 hours using Lactated Ringer's. Half is given in the first 8 hours post-burn (not transfer).

Kaava

Fluid (mL) = 4 × Body weight (kg) × %TBSA burned; Give half in first 8 hours, half in next 16 hours; Use Lactated Ringers (LR) solution

Weight: Body weight (kg)
TBSA: Total body surface area burned (Percentage (Rule of 9s))
Fluid4Hrs: Fluid in first 8 hours (mL)
Fluid16Hrs: Fluid in next 16 hours (mL)

Usein kysytyt kysymykset

What's the Rule of 9s for %TBSA?

Head/neck: 9%, Each arm: 9%, Chest: 18%, Abdomen: 18%, Each leg: 18%, Perineum: 1%. Measure by body part involvement. Children differ (head 18%, leg 14%).

Why Lactated Ringers (LR) vs normal saline?

LR isotonic, contains potassium, more physiologic. NS can cause hyperchloremic acidosis. LR preferred in burn resuscitation (evidence-based). Monitor urine output (goal 0.5 mL/kg/hr adults).

Is Parkland formula always enough?

Starting point; adjust based on clinical response. Goal: urine output 0.5 mL/kg/hr (1 mL/kg/hr if inhalation injury). May need more in lightning strike, electrical burns. Serial labs essential.
