Study Notes
Burn Injuries
- Severe burns covering more than 15% of body surface area are often fatal.
Nutritional Care after Burn Injury
- During the Ebb phase, the focus of nutritional care is on providing sufficient calories and protein to support wound healing and minimize muscle catabolism.
Ebb Phase Characteristics
- The Ebb phase is characterized by a hypermetabolic response, where the body's energy expenditure increases to combat the injury.
Burn Degrees
- First-degree burns are characterized by erythema, pain, and edema, but do not involve the epidermal layer.
Infection Susceptibility
- Damaged skin and body surfaces are more susceptible to infections because they provide a portal of entry for bacteria, and the body's natural defense mechanisms are compromised.
Burn Types
- Third-degree burns lead to the total loss of skin, including the fat layer, hair follicles, and sweat glands.
- Fourth-degree burns typically require skin grafting due to insufficient skin for healing.
Body Surface Area Assessment
- The 'rule of nines' is used to estimate the percentage of body surface area burnt, with 15% or more usually being fatal in a person with extensive burns.
- The Lund-Browder chart is used to assess the total body surface area burnt in a patient with burns.
Mortality Prediction
- The Abbreviated Burn Severity Index (ABSI) is a scoring system used as a 'rule of thumb' for predicting mortality after severe burn injury.
