Full thickness burns, also known as third-degree burns, are the most severe type of burns. They involve the entire thickness of the skin and can extend to underlying tissues such as fat, muscle, or bone. Here are the pathophysiological changes that occur in full thickness burns:

1. **Coagulation Necrosis**: The immediate response to a full thickness burn is coagulation necrosis, where the proteins in the skin cells denature due to the extreme heat, causing the cells to die.

2. **Inflammatory Response**: The body's immune system responds to the injury by increasing blood flow to the area and sending white blood cells to fight potential infection. This results in inflammation, redness, and swelling.

3. **Fluid Loss**: The damaged skin can no longer prevent fluid from seeping out into the surrounding tissues. This can lead to dehydration and electrolyte imbalances, which can affect the function of the heart and other organs.

4. **Thermoregulation Disruption**: The skin plays a crucial role in regulating body temperature. With the loss of intact skin, the body may have difficulty maintaining its normal temperature, leading to hypothermia or hyperthermia.

5. **Infection**: The skin acts as a barrier to bacteria and other pathogens. When this barrier is compromised, there is a high risk of infection, which can further complicate the healing process.

6. **Healing and Scar Formation**: Full thickness burns often require skin grafts as they cannot heal on their own. The healing process can lead to the formation of scar tissue, which may limit mobility and function, depending on the location of the burn.

7. **Psychological Impact**: The physical changes and pain associated with full thickness burns can also lead to psychological distress, including anxiety, depression, and post-traumatic stress disorder (PTSD).
