How do acute and chronic wounds differ?

• A. Chronic wounds heal quickly compared to acute
• B. Acute wounds heal in days to weeks; chronic wounds persist beyond normal healing time and may stall in inflammatory phase
• C. There is no difference between acute and chronic wounds
• D. Chronic wounds heal in days, while acute wounds stall

Answer: (B)

Understanding how acute and chronic wounds differ is about healing timelines and the wound’s biology. Acute wounds follow a normal healing sequence with a brief inflammatory phase, then proliferative and remodeling phases, and they typically close in days to weeks. Chronic wounds, however, persist beyond the usual healing window and often stall in the inflammatory phase, so they struggle to progress through the healing stages. This prolonged inflammatory state, along with factors such as poor blood flow, infection, edema, malnutrition, and systemic diseases like diabetes, interferes with granulation, epithelialization, and tissue remodeling. Clinically, chronic wounds tend to drain longer, show more bioburden or necrotic tissue, and fail to improve with standard care, unlike acute wounds that heal as expected. So the statement that acute wounds heal in days to weeks while chronic wounds persist beyond normal healing time and may stall in the inflammatory phase captures the essential difference.
