Early cause of death due to burns is :
**Core Concept**
The early cause of death due to burns involves a complex interplay of systemic responses to injury, including inflammation, coagulation, and cardiovascular instability. The pathophysiology of burn shock is characterized by a systemic inflammatory response, leading to microvascular dysfunction, hypovolemia, and ultimately, multiple organ failure.
**Why the Correct Answer is Right**
The early cause of death due to burns is primarily due to **burn shock**. This occurs as a result of the release of inflammatory mediators, such as histamine, bradykinin, and prostaglandins, which cause vasodilation, increased vascular permeability, and fluid loss into the interstitial space. This leads to hypovolemia, decreased cardiac output, and subsequently, inadequate perfusion of vital organs. The burn injury also triggers a hypermetabolic response, characterized by increased catecholamine release, cortisol production, and insulin resistance, further exacerbating the cardiovascular instability.
**Why Each Wrong Option is Incorrect**
* **Option A:** Not relevant to early cause of death due to burns.
* **Option B:** Not a primary cause of death in the early stages of burn injury.
* **Option C:** Not directly related to the pathophysiology of burn shock.
**Clinical Pearl / High-Yield Fact**
Burn shock is a preventable cause of death, and timely fluid resuscitation is critical in preventing hypovolemia and maintaining adequate organ perfusion. The Parkland formula (4 mL/kg/%TBSA burned in the first 24 hours) is a widely used guideline for fluid resuscitation in burn patients.
**Correct Answer:** C. Burn shock.
