Achieving Wound Care Protein Requirements Without Consuming Excessive Calories
by Mary Ellen Posthauer RDN, CD, LD, FAND
Previously, I discussed the value of protein for wound healing. Protein is responsible for cell multiplication, repair, and synthesis of enzymes involved in wound healing. Protein supplies the binding material of skin, cartilage, and muscle. The 2009 National Pressure Ulcer Advisory Panel/European Pressure Ulcer Advisory Panel (NPUAP/EPUAP) guidelines recommend 1.2-1.5 grams of protein/kilogram of body weight for individuals with pressure ulcers, when compatible with goals of care.
After completing a nutrition assessment, the dietitian determines the calorie, fluid, and protein requirements for the individual with pressure ulcers. However, there are times when increasing total caloric intake to achieve the recommended protein level would not be beneficial. For example, an individual on enteral nutrition may be receiving adequate calories and fluids per his requirements, and could not tolerate the additional volume required to meet his protein needs. An obese individual with wounds requires additional protein, but excessive calories would not be beneficial. These are two examples when modular protein should be considered.
Modular Protein Supplements
There are many modular protein supplements on the market today including powdered and liquid products. Modular protein supplements may have soy, whey protein isolate, casein, or a hydrolyzed collagen fortified with tryptophan. The protein ranges from 7-20 grams per ounce or serving and 25-100 calories. They can be added to an enteral feeding or taken orally. An advantage of the liquid supplement is that is can be taken orally without mixing it into a food or beverage. When selecting a modular protein supplement consider the following:
- Protein source (does the product contain all of the essential amino acids?)
- Grams of protein per serving (can you achieve the protein goal with one or two servings?)
- Taste, if taken orally (consider testing products for taste and mouth feel)
- Ease of mixing (a prime consideration for a powdered product)
- Ability to mix into both hot and cold foods/beverages (powdered products state the hot beverage should not be greater than 180 degrees)
- Lactose free
- Cost per gram of protein
The dietitian should discuss the recommendation for a modular protein supplement with the wound care team and the patient prior to requesting a physician’s order. The intake of the supplement should be tracked in the patient’s medical record as part of the monitoring process. When the skin is intact, consider discontinuing the supplement.
