Abstract
During the rehabilitation phase of burn injury, patient care transitions from critical care medicine to restorative treatment strategies that encompass physical and occupational therapies, nutrition repletion, and psychosocial support for community reintegration. As pediatric burn patients undergo rehabilitation, nutrition assessment remains ongoing to define nutritional status and any alterations in metabolism that may take place. For some, a persistent hypermetabolic state appears evident, and weight loss may continue. The severity and duration however varies among patients. Many patients enter their rehabilitative phase with visible lean body mass depletion, and the focus of nutritional therapy for them shifts to replenishing nutritional status, while supporting rehabilitative efforts. Over the past decade, we have conducted studies on energy and protein metabolism, body composition, including bone mineralization, and general wellness in over 130 patients to better understand changes in metabolism and nutritional status during the rehabilitative phase of recovery. This abstract summarizes our findings.Entities:

Figure 1Changes of body composition during health and the acute and rehabilitative phases of burn injury. Body composition and its components are shown during health and the acute and rehabilitative phases of care. LBM = lean body mass; ICW = intracellular water; ECW = extracellular water; ECS = extracellular solid. Throughout these phases, overall lean body mass can go unchanged; alterations in water and protein components however take place.

Highlight of key metabolic processes requiring nutritional assessment and intervention during the rehabilitative phase of care
|
|
|
|
|
|---|---|---|---|
| Protein synthesis and breakdown | Increased synthesis and breakdown. Skeletal muscle breakdown is normal. Exogenous protein can diminish protein breakdown rate. | Nitrogen balance | Provide 2.5 g/kg of protein to cover obligatory losses. Maintain nitrogen balance in the positive by 2 g protein/kg day. |
| Pre-albumin, CRP | |||
| Weekly | |||
| Energy expenditure | Resting energy expenditure declines for most patients. Increased total energy expenditure due to increased physical activity. | Indirect calorimetry | Hypermetabolic: REE × 1.2 |
| Normal REE/intensive physical therapy: REE × 1.5 or 65 kcal/kg (to meet increased needs with physical activity) | |||
| Weekly | |||
| Bone mineral density | Altered vitamin D metabolism and bed rest results in large majority of burn patients to have mild to moderate bone loss following severe burn injury. Malnutrition increases the odds of having severe bone depletion. | DXA every 6 weeks | For bone mineral density |
| >−1.0: no intervention | |||
| Weekly | <−1.0: vitamin D3/calcium supplementation | ||
| 4–8 years: 1,000 mg/600+ IU | |||
| 9–18 years: 1,500 mg/600+ IU | |||
| <−2.0 as above with 0.1–0.2 mg/kg oxandrolone | |||
| Growth | Growth delay is apparent in children with massive burn injury, effecting height more than weight. | Height and weights | Energy and protein as above to promote age appropriate rate of weight gain. |
