Summary
Burns are injuries to body tissue from various sources. Students learn about the effects of burns, how to assess and treat them, and how to calculate fluid and nutritional needs.
Burns and their effects
Burns are caused by heat, cold, chemicals, electricity, or radiation. The extent of burns is calculated by the percent of total body surface area (TBSA) burned. Burns are classified by degree and thickness.
Burns and the body
Burns affect several body systems, including cardiovascular, respiratory, immune, gastrointestinal, genitourinary, and neurologic. The body goes through three phases of burn physiology: emergent, acute, and rehabilitation.
Calculating fluid and nutritional needs
Fluid requirements for burn patients are calculated using the Parkland formula. Nutritional needs are calculated based on body mass index (BMI) and daily caloric requirements. A high-calorie, high-protein diet is important for healing.
Inhalation injury and its treatment
Inhalation injury can occur with burns. Assessment findings indicate its presence. Treatment protocols are described for burn patients with or suspected of having an inhalation injury.
Key terms
- Total Body Surface Area
- The extent of burns is calculated by the percent of total body surface area burned.
- Lund-Browder chart and Rule of Nines
- Partial- and full-thickness burn extent can be determined using TBSA based on the Lund-Browder chart and Rule of Nines.
- Parkland formula
- Fluid requirements for burn patients are calculated using the Parkland formula.
- Body Mass Index
- Nutritional needs are calculated based on body mass index.
- Inhalation injury
- Inhalation injury can occur with burns, and assessment findings indicate its presence.
- Hypermetabolic state
- After a major burn injury, a hypermetabolic state occurs which may cause massive catabolism.
