This alone has been found to be 80 to 90 percent accurate in evaluating patient nutritional status, and the addition of multiple or complex biochemical, immune, or anthropometric measurements does not increase greatly the accuracy of nutritional assessment.
Determining who would truly benefit from nutritional supplementation is still a matter of some debate, but there is evidence that preoperative nutritional support reduces infectious complications and anastomotic breakdown in severely malnourished patients undergoing major elective surgery.Postoperative nutritional support should be considered in patients expected to be unable to eat for a period of at least 2 weeks.
- Enteral feeding is superior to parenteral feeding when possible.
- Fish oil supplements (omega-3 fatty acids) adversely impacts the healing response.
- Vitamin C deficiency, in addition to impairing wound healing, has also been associated with an increased susceptibility to wound infection. Burn victims require as much as 1 to 2 g/day to restore urine and tissue levels to normal.
- Vitamin A deficiency impairs wound healing. Vitamin A, administered either topically or systemically, reverses the antiinflammatory effects of corticosteroids on wound healing.
- The antiinflammatory properties of vitamin E are similar to those of steroids. Vitamin A can reverse the wound-healing impairment induced by vitamin E. Vitamin E has also been shown to affect various host immune functions, often in a negative fashion.
- Zinc deficiency impairs the critical roles each of these processes play in wound healing. Zinc levels less than 100 μg/dl have been associated with decreased fibroblast proliferation and collagen synthesis.
