How long does the ebb response following burn injury last?

• A. 3-5 days
• B. 1-2 days
• C. 6-8 days
• D. 2-3 weeks

Answer: (A)

After a burn, the body goes through an early ebb phase in which perfusion is reduced and metabolic activity is depressed. This is a transient hypodynamic period that sets the stage for the later hypermetabolic flow phase. The ebb response typically lasts several days, commonly about 3–5 days, before the body shifts into the flow phase with increased cardiac output and higher energy expenditure. The other timeframes are too short or too long to reflect this initial hypoperfused, energy-conserving period that precedes the hypermetabolic response.
