A woman was brought to the casualty 8 hours after sustaining burns on the abdomen, both the limbs and back. What will be the amount of fluid to be used for resuscitation in the first 24 hours as per Parkland formula?
**Core Concept**
Burns cause fluid loss due to damage to the skin and underlying tissues. The Parkland formula is a widely accepted method for calculating the amount of fluid required for resuscitation in the first 24 hours after a burn injury.
**Why the Correct Answer is Right**
The Parkland formula calculates the amount of fluid required based on the percentage of total body surface area (TBSA) burned and the patient's weight. The formula is: Total fluid (in mL) = 4 mL x weight (in kg) x % TBSA burned. In this case, the patient has burns on the abdomen, limbs, and back. Assuming the burns cover approximately 30% of the TBSA, the calculation would be: Total fluid (in mL) = 4 mL x weight (in kg) x 30. The Parkland formula recommends administering half of the calculated fluid in the first 8 hours and the remaining half in the next 16 hours.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because the Parkland formula does not take into account the age of the patient or the presence of inhalational injury.
* **Option B:** This option is incorrect because the formula does not require the administration of all the calculated fluid within the first 8 hours, but rather half of it.
* **Option C:** This option is incorrect because the Parkland formula is not based on the patient's age or the presence of inhalational injury.
**Clinical Pearl / High-Yield Fact**
The Parkland formula is a simple and widely accepted method for calculating the amount of fluid required for resuscitation in the first 24 hours after a burn injury. It is essential to calculate the total body surface area burned accurately to avoid under- or over-resuscitation.
**Correct Answer:** 4 mL x weight (in kg) x % TBSA burned.
