Burns - Pathophysiology and find out the main aim of burns resuscitation

Pathophysiology of Burns:

1. Thermal Injury: When the skin is exposed to a heat source, it causes coagulative necrosis, a type of cell death where the proteins in the cell are denatured. This leads to the formation of a burn wound.

2. Inflammatory Response: The body responds to the burn injury by releasing inflammatory mediators like histamines, cytokines, and prostaglandins. These mediators increase the permeability of the blood vessels, leading to fluid loss from the blood vessels into the tissues, causing edema or swelling.

3. Hypermetabolic Response: The body also responds to the burn injury by increasing the metabolic rate to provide energy for wound healing and immune response. This can lead to weight loss and muscle wasting if not properly managed.

4. Immunological Response: The immune system is also affected by burn injuries. There is a decrease in the number of immune cells and a suppression of the immune response, making the patient more susceptible to infections.

Main Aim of Burns Resuscitation:

The main aim of burns resuscitation is to restore the fluid balance and prevent shock. This is done by replacing the fluids lost through the burn wound and the increased vascular permeability. The fluids are usually replaced with a combination of crystalloids (like saline) and colloids (like albumin). The amount of fluids to be given is calculated based on the patient's weight and the extent of the burn. Other aims of burns resuscitation include pain management, prevention of infection, and wound healing.
