Как да изчислим Parkland Formula
Какво е Parkland Formula?
Parkland formula estimates fluid requirements for burn resuscitation. It guides IV fluid administration in the first 24 hours post-burn.
Формула
Calculate: Volume (mL) = 4 × body weight (kg) × %TBSA burned
Ръководство стъпка по стъпка
- 1Calculate: Volume (mL) = 4 × body weight (kg) × %TBSA burned
- 2Give half in first 8 hours, half over next 16 hours
- 3Use Ringer's lactate; monitor urine output and adjust
Worked Examples
Вход
70 kg patient with 40% TBSA burn
Резултат
Total 24hr fluids = 11,200 mL; give 5,600 mL in first 8 hours
Using Ringer's lactate
Common Mistakes to Avoid
- ✕Including inhalation injury fluid in formula (requires separate consideration)
- ✕Forgetting to subtract pre-hospital fluids received
Frequently Asked Questions
Why Ringer's lactate instead of normal saline?
Ringer's has lower sodium and adds lactate, better matching extracellular fluid and preventing hyperchloremic acidosis.
Is Parkland formula always accurate?
It's a starting estimate; titrate fluids based on urine output (0.5 mL/kg/hr) and clinical response.
