Oral nutritional supplements effective in treating Chronic resistant Wounds
Nutrition supplements enriched with immune function enhancing nutrients have been developed to aid wound-healing. A recent study suggests that the intake of specialized oral nutritional supplements have a significant therapeutic effect in treating hard to heal wounds. The research has been published in the Journal of Wound Care on January 13, 2021.
Under-nutrition, inadequate protein or poor protein and energy intake and unintended weight loss have been identified as independent risk factors for the development of pressure ulcers. Providing oral nutritional supplements (ONS) in addition to regular food intake seems a logical way to replenish body shortages of macro-and micronutrients as well as to supply extra nutrients for the preservation of skin tissue, strengthening of tissue resistance, and promoting tissue repair. Therefore, researchers of Brazil conducted a study to evaluate the effects of a specialised oral nutritional supplement (ONS) containing arginine and proline, with high vitamin A, C and E, zinc and selenium content, on the repair of hard-to-heal wounds.
It was a randomized control prospective study in 30 patients who were evaluated at five-time points (S0–S4) over four consecutive weeks. At baseline (S0), patients were randomised to the specialised ONS (n=15; 25 wounds) or control (n=15; 25 wounds) groups with a dosage of 200ml twice daily. Researchers monitored the Wound surface area and perimeter. In addition to the metric data, the researchers also calculated the rate of wound contraction and the linear growth of the wound edges, looking for wound-healing predictive factors.
