Pro-Stat® AWC
Indications for Use
Many patients in long-term health care facilities develop pressure ulcers, or bed sores.1,2 The Agency for Health Care Policy and Research's (AHCPR) guidelines for Treatment of Pressure Ulcers indicate that patients with pressure ulcers need 30 to 35 kilocalories and 1.25 to 1.5 grams of protein per kilogram of body weight daily, and increased requirements for L-Arginine, L-Cystine, Vitamin C, and Zinc3. Pro-Stat® Advanced Wound Care is a high calorie, complete protein liquid, with added Arginine, Cystine, Zinc, and Vitamin C.
Protein
Pro-Stat® Advanced Wound Care contains enriched collagen protein providing a naturally occurring high nitrogen mix of all essential, conditionally essential and non-essential amino acids that is hydrolyzed (pre-digested) using papain, a fruit enzyme. In this hydrolysate form, the protein is present in its elemental components -- free amino acids peptides -- thereby increasing absorption and assimilation by the body. Pro-Stat is
naturally rich in Arginine, Glycine, Proline and Hydroxyproline, high nitrogen donor amino acids that are a critical factor in replenishing depleted protein stores and accelerating tissue healing in patients with pressure ulcers.
Arginine
The physiological demands of repair and recovery from wounds, burns, sepsis and trauma (including surgical trauma) often require greater amounts of L-arginine than can be synthesized by the body. Additional dietary intake of L-arginine is indicated when these conditions are present:
- Needed to promote protein regeneration and the healing of wounds.4
- Essential when the body is under stress or in an injured state.5
- Conditionally essential, particularly during growth, illness or metabolic stress when the body’s production may be insufficient to meet demands.6
- Improves markers of wound healing with greater protein and hydroxyproline in the wound bed and promotion of positive nitrogen balance.7
Ascorbic Acid (Vitamin C)
Vitamin C is essential for wound healing and for the repair and maintenance of cartilage, bones, and teeth. Vitamin C deficiency can lead to a decreased wound-healing rate. The body does not manufacture vitamin C on its own, nor does it store it.8, 9
- Promotes collagen synthesis and enhances activation of leukocytes and macrophages to the wound site.9
- Promotes healthy cell development, proper calcium absorption, normal tissue growth and repair - such as healing of wounds and burns.9
- Required for the growth and repair of tissues in all parts of the body. 9
- Necessary to form collagen, an important protein used to make skin, scar tissue, tendons, ligaments, and blood vessels. 9
Zinc
Zinc has been shown to be beneficial to wound healing and zinc deficiency has been associated with delayed wound healing.10, 11
- Assists in immune function and interacts with platelets in blood clotting.12
- When zinc supplements are given to individuals with low zinc levels, the numbers of T-cell lymphocytes circulating in the blood increase and the ability of lymphocytes to fight infection improves.12
