Curling’s ulcer is seen if burns area is more than
**Core Concept**
Curling's ulcer is a type of acute peptic ulceration that occurs in patients with severe burns. The pathophysiology involves the release of various chemical mediators and the activation of different pathways that lead to mucosal damage and ulceration. The severity of the burn is a critical factor in the development of Curling's ulcer.
**Why the Correct Answer is Right**
The correct answer is related to the severity of the burn. Curling's ulcer typically occurs when the burn area exceeds 20-30% of the total body surface area (TBSA). This is because the stress response to severe burns involves the release of stress hormones such as cortisol and catecholamines, which can lead to gastric mucosal damage and ulceration. The burn area of 20-30% TBSA is generally considered a threshold beyond which the risk of Curling's ulcer significantly increases.
**Why Each Wrong Option is Incorrect**
* **Option A:** Burns covering less than 10% of TBSA are not typically associated with Curling's ulcer, as the severity of the burn is not sufficient to trigger a significant stress response.
* **Option B:** Burns covering 15-20% of TBSA may be associated with some risk of Curling's ulcer, but it is not as high as the risk seen with burns covering 20-30% TBSA.
* **Option C:** Burns covering more than 40% of TBSA are associated with a very high risk of Curling's ulcer, but the correct answer is the threshold beyond which the risk significantly increases.
**Clinical Pearl / High-Yield Fact**
When assessing a patient with severe burns, it is essential to monitor for signs of Curling's ulcer, such as abdominal pain, nausea, and vomiting, especially if the burn area exceeds 20-30% TBSA.
**Correct Answer: C. 20-30%**
