32 year old female presents with 15% burns following cylinder blast. How much fluid should be administered in first 8 hours of admissions, if she weighs 60 kg
## Core Concept
The question pertains to the management of burns, specifically the administration of fluids in the initial stages following a burn injury. The **Parkland formula** is a widely used guideline for calculating the amount of fluid resuscitation required for burn patients in the first 24 hours.
## Why the Correct Answer is Right
The Parkland formula calculates the total amount of fluid required in the first 24 hours as 4 mL/kg/% total body surface area (TBSA) burned. For this patient, who has 15% burns and weighs 60 kg, the total fluid required in 24 hours would be 4 mL/kg/%TBSA * 60 kg * 15% = 3600 mL. The Parkland formula recommends that half of this total volume should be administered in the first 8 hours post-burn. Therefore, the amount to be administered in the first 8 hours is 3600 mL / 2 = 1800 mL.
## Why Each Wrong Option is Incorrect
- **Option A:** This option suggests a significantly lower volume of fluid, which would likely result in inadequate resuscitation and potential organ hypoperfusion.
- **Option B:** Similar to Option A, this suggests a lower volume than calculated by the Parkland formula, potentially leading to under-resuscitation.
- **Option D:** This option suggests a higher volume than required according to the Parkland formula, which could lead to over-resuscitation and complications such as abdominal compartment syndrome.
## Clinical Pearl / High-Yield Fact
A key point to remember is that the Parkland formula provides a guideline for the initial management of burn patients, and it is crucial to monitor the patient's response to fluid resuscitation (e.g., urine output) to adjust the fluid therapy as needed. The formula is 4 mL/kg/%TBSA burned, and half of the calculated 24-hour fluid volume should be administered in the first 8 hours.
## Correct Answer Line
**Correct Answer: C. 1800 mL.**
