Best fluid for resuscitation in burns: FMGE 11; Punjab 12
**Core Concept**
The primary goal of fluid resuscitation in burn patients is to restore circulating volume, maintain organ perfusion, and prevent shock. This is achieved by administering a fluid that is isotonic and has a similar composition to the patient's plasma, allowing for effective distribution and absorption.
**Why the Correct Answer is Right**
The best fluid for resuscitation in burns is lactated Ringer's solution. This is because lactated Ringer's solution is an isotonic crystalloid that closely mimics the electrolyte composition of human plasma, making it ideal for restoring circulating volume and maintaining organ perfusion. It contains sodium (130 mEq/L), chloride (109 mEq/L), potassium (4 mEq/L), calcium (3 mEq/L), and lactate (28 mEq/L), which helps to replenish lost ions and maintain acid-base balance.
**Why Each Wrong Option is Incorrect**
* **Option A:** Normal saline is hypertonic and can lead to hyperchloremic acidosis, which may worsen the patient's condition.
* **Option B:** 5% dextrose solution is hypotonic and can exacerbate hypovolemia, making it unsuitable for resuscitation in burns.
* **Option C:** Colloids, such as albumin, are not recommended as the primary fluid for resuscitation in burns due to their high cost and lack of proven benefit.
**Clinical Pearl / High-Yield Fact**
In the management of burn patients, it's essential to remember the Parkland formula for fluid resuscitation: 4 mL/kg/% total body surface area (TBSA) burned of lactated Ringer's solution over the first 24 hours, with half given in the first 8 hours.
**Correct Answer: C. Colloids, such as albumin, are not recommended as the primary fluid for resuscitation in burns due to their high cost and lack of proven benefit.**
