Term
What is the recommended protein intake for patients with pressure ulcers?
Definition
  • 1.2-1.5 g/kg

30-40 mL/kg or 1-1.5 mL/kcal with a minimum of 1500 mL per day
Term
What factors should be considered when estimating fluid needs for pressure ulcer patients?
Definition
  • Fever
  • Draining wounds
  • Stool/ostomy output
  • Air-fluidized beds
Term
How do multivitamin/multimineral supplement recommendations vary by stage of PU?
Definition
  • Stage 1-2: give multivitamin/multimineral supplement IF oral/enteral intake inadequate to meet 100% of RDA
  • Stage 3-4: Give multivitamin/multimineral supplement at RDA/DRI level
  • Maximum: multivitamin/multimineral supplement twice daily
Term
What are the recommendations for vitamin C supplementation for patients with pressure ulcers?
Definition
  • Stage 1-2: 100-200 mg vitamin C per day
  • Stage 3-4: up to 1000-2000 mg/d in divided doses for stressed patients or those at risk of deficiency; reassess after 10-14 days
  • Maximum: 2000 mg vitamin C per day
Term
What are the recommendations for zinc supplementation in patients with pressure ulcers?
Definition
  • Stage 1-2: if deficiency suspected, give up to 220 mg zinc sulfate (50 mg elemental zinc) twice daily for 10-14 days
  • Stage 3-4: 25-40 mg elemental zinc per day; same recs as for stage 1-2 if deficiency is suspected
  • Maximum: if severe deficiency or significant wound/GI losses, give up to 150 mg elemental zinc per day x2 weeks

  • Maximum: 25k-50k units per day x10-14 days
Term
What are the recommendations for arginine supplementation in patients with pressure ulcers?
Definition
There are no evidence-based recommendations for arginine use in chronic wounds
Term
What are the recommendations for glutamine supplementation in patients with pressure ulcers?
Definition
Glutamine appears to play an indirect role in wound healing, but supplementation has not been shown to have a noticeable effect on wound healing
Term
What are the recommendations for vitamin E supplementation in the context of wound healing?
Definition
Vitamin E delays wound healing and decreases tensile strength of wounds
Term
Should supplemental zinc be given to patients with pressure ulcers if deficiency is not suspected?
