Which crystalloid fluid is commonly recommended for initial burn resuscitation and why?

• A. Lactated Ringer's solution is preferred because its electrolyte composition approximates plasma and it avoids hyperchloremic acidosis associated with large volumes of normal saline.
• B. Normal saline is preferred due to higher chloride content.
• C. Dextrose saline is preferred for energy.
• D. Albumin is the first-line resuscitation fluid.

Answer: (A)

In the early phase of burn resuscitation, the goal is to rapidly restore intravascular volume with a fluid that won’t disrupt acid-base balance or electrolytes. Lactated Ringer’s is preferred because its electrolyte composition mirrors plasma (sodium, potassium, calcium, chloride) and it contains lactate that is metabolized to bicarbonate. This provides a buffering effect that helps prevent metabolic acidosis during heavy fluid resuscitation, which can otherwise worsen tissue edema and organ perfusion.

Normal saline, given in large volumes, delivers a higher chloride load and can cause hyperchloremic metabolic acidosis, contributing to impaired perfusion. Dextrose-containing fluids don’t address intravascular volume and can cause unnecessary fluctuations in blood glucose. Albumin, a colloid, is not used first-line for initial burn resuscitation; it’s typically considered later or in specific situations after adequate crystalloid resuscitation has begun.

So, Lactated Ringer’s is favored because its composition closely resembles plasma and it helps avoid the acid-base disturbances associated with large-volume normal saline boluses.
