如何计算Parkland Formula
learn.whatIsHeading
Parkland formula estimates fluid requirements for burn resuscitation. It guides IV fluid administration in the first 24 hours post-burn.
公式
Calculate: Volume (mL) = 4 × body weight (kg) × %TBSA burned
分步指南
- 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
例题解析
输入
70 kg patient with 40% TBSA burn
结果
Total 24hr fluids = 11,200 mL; give 5,600 mL in first 8 hours
Using Ringer's lactate
常见错误注意事项
- ✕Including inhalation injury fluid in formula (requires separate consideration)
- ✕Forgetting to subtract pre-hospital fluids received
常见问题
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.
