At what percentage of total body surface area should an IV be administered to a burn victim?

In cases of burn victims, the determination of fluid resuscitation needs is often based on the percentage of total body surface area (TBSA) affected by burns. The general guideline suggests that when a patient has sustained burns covering approximately 20% or more of their total body surface area, intravenous (IV) fluids should be administered to prevent hypovolemic shock and ensure adequate tissue perfusion.

Administering IV fluids becomes critical because burns can lead to significant fluid loss due to plasma leaking from damaged tissues. Therefore, starting IV fluids at the threshold of 20% TBSA allows for early intervention that can greatly impact outcomes. Proper fluid resuscitation can help stabilize the patient's condition as further evaluation and treatment occur.

This percentage is derived from established protocols in trauma care, making it a crucial aspect of managing burn injuries effectively.
