How long does the shock phase last after a burn?

The duration of the shock phase following a burn typically ranges from 24 to 48 hours. This phase, also known as the hypermetabolic phase, is characterized by a significant physiological response to the injury, including changes in heart rate, blood pressure, and fluid balance. During this period, the body experiences widespread inflammation and a high level of stress mediators, which can lead to complications if not managed properly.

Burn injuries cause damage to skin layers, leading to loss of fluids and electrolytes, potentially resulting in shock if not addressed. The 24 to 48-hour timeframe is critical for monitoring a patient’s hemodynamic status, ensuring adequate fluid resuscitation to prevent complications such as acute kidney injury or respiratory distress.

In contrast, other options suggest shorter or longer durations that do not align with the established medical understanding of the body's response to burns in the initial aftermath. Understanding this window is vital for providing appropriate and timely care to those affected by burns.
