During the resuscitation phase of burn treatment, which acid-base imbalance is commonly observed?

During the resuscitation phase of burn treatment, metabolic acidosis is commonly observed. This occurs primarily due to a combination of factors associated with burns, such as tissue hypoperfusion and subsequent lactic acid buildup. When burns occur, significant fluid loss can lead to reduced blood volume and, consequently, decreased oxygen delivery to tissues. In the absence of adequate oxygen, the body shifts to anaerobic metabolism, resulting in increased production of lactic acid, which causes a decrease in blood pH, manifesting as metabolic acidosis.

Additionally, the release of inflammatory mediators in response to burns can further contribute to this acid-base disturbance. As such, recognizing metabolic acidosis during the resuscitation phase is crucial for proper management, ensuring that fluid resuscitation and other interventions adequately address this imbalance.
