Why is fluid resuscitation critical within the first 24 hours post-burn?

Fluid resuscitation is vital within the first 24 hours post-burn primarily to restore intravascular volume and prevent shock. In cases of significant burns, the body experiences a loss of fluid due to increased capillary permeability, leading to a shift of plasma into the interstitial space. This can result in hypovolemia and, subsequently, inadequate tissue perfusion. Without prompt and appropriate fluid resuscitation, patients can enter hypovolemic shock, which can further compromise organ function and overall recovery.

Prioritizing intravascular volume restoration allows for better perfusion of vital organs, maintaining circulation and oxygenation critical for patient survival. It also helps to stabilize the patient's condition, allowing other interventions, such as pain management and wound care, to be effectively implemented.

While enhancing wound healing, minimizing pain, and aiding mobility are important aspects of post-burn care, they are secondary to the immediate need for fluid resuscitation to maintain hemodynamic stability and prevent shock in the acute phase after a burn injury.
