Problem: Infection is a major problem in the health and wellbeing of patients in hospitals, nursing homes, and other medical facilities as well as the homecare patients and the general public. According to Scientia Advisors, wound care costs the healthcare system over $7 billion in 2009. After adding the cost associated with potential complications such as infections, extended physician care, and lengthy hospital stays, the annual wound care expenditures well exceeded over $20 billion.1 There are 20 million reported cases of diabetes per year and more every day. Because of the fact that leg ulcers are the number one health problem of men coupled with the rise in drug resistance of infections, the importance of providing the professional and the public with relatively simple and affordable wound care is of extreme importance. Often the wounds can become chronic wounds, which then result in long-term nursing expense in time and supplies or, worse yet, can result in expensive amputations ranging from $5000 to $40,000 per patient.
Solution: There are many dressing options now available for treating wounds with components such as glycerin, honey, salt, and many other natural products, with some dressings being more appropriate than others. In 1988, a patented glycerin-based dressing was introduced to the market, called Elasto-Gel™.2.
New technology: Elasto-Gel™ is a glycerin-based gel sheet (65%) combined with a hydrophilic polymer that causes the sheet to absorb the exudate from the wound and simultaneously release the glycerin from the gel, which adds many benefits to the wound for excellent healing outcomes. The gel sheet is 1/8th of an inch thick with a four-way stretch backing. It has the ability to absorb 3-4 times its own weight of fluids. The dressing will not dry out or allow the exudate to dry out, thus keeping the dressing from becoming bonded to the wound or the surrounding tissue. It does not have adhesive properties and, therefore, will not cause damage to the wound bed or periwound area upon dressing removal. Because of the thickness, the product provides excellent cushion and padding support. It has been also proven to be bacteriostatic/fungistatic. (Bacteriostatic is the ability to restrain the development or reproduction of bacteria.3).
Product technology: Glycerin is a huamectant by definition and has been recognized by the U.S. Food and Drug Administration (FDA). Humectants attract, bind, and hold moisture to the site of application. The actual concentration of glycerin in a wound dressing is indicative of the ability to absorb excess moisture. Exudate management is an important function of topical treatment. The ability to absorb drainage and prevent pooling of exudate in the wound or on the surrounding skin are attributes specific to high glycerin content. Perhaps, the most significant advantage of the glycerin-based hydrogel sheet is its impact on wound bioburden and pathogenic organisms.4 Glycerin is a simple three-carbon tri-alcohol and is a natural humectant. It is used as a carrier in many medicines and as plasticizer in gelatin gel capsules. Glycerin is a component of cosmetics, conditioners, soaps, foods, and other common products. It is a component of mono-, di-, and triglycerides naturally occurring in the body. These glycerides and glycerin are constantly reacted with each other by the natural enzymes and reversed with the natural metabolic processes already present in the body. Any glycerin that may be absorbed into the body fluid is rapidly diluted in these fluids and is no longer toxic but is metabolized as another component of the food chain. It is well known that glycerin in high concentration will exhibit dehydrating effect on many systems including living cells by the commonly known process of osmosis. (Osmosis: the flow or diffusion that takes place through a semipermable membrane, as of living cell, typically separating a solvent such as water, thus bringing about equilibrium conditions.5) It has been shown that glycerin at high concentration will be cytotoxic to all cells that have been tested if they are exposed long enough. These properties of glycerin have been recognized by the European Skin Bank, where they use 85% glycerin solutions to store cadaver skin at ∼42F, and can be used for potential wound coverings. The cadaver skin that has been prepared by this method has been available since 1994.6 The concern for safety resulted in a three-day international synmposium7 with emphasis on glycerin-preserved cadaver skin providing healthy environment for the preserved skin to be successfully accepted without rejection, having no complications of infection and providing excellent healing outcomes and minimal scaring. Additional research by Dr. David P. Mackie of the Red Cross Hospital, The Netherlands, reported that using 85% glycerin solutions had slow bactericidal effects and also showed virocidal activity on several types of viruses.8 Dr. Hoekstra has observed that within 2 hours after application of Elasto-Gel™, the inflammatory reaction is reduced.9 Vandeputte, Belgium, showed that wounds covered with Elasto-Gel™ had fewer myofibroblasts than those covered with hydrocolloid.10 It has been proposed that myofibroblasts in high concentrations contribute to the formation of hypertrophic and keloid scars. As noted earlier, there is less scar formation when glycerin-based gel sheets are used. The data sited here have shown that glycerin and glycerin-based products are effective antimicrobial agents with less side effects. Many verbal reports along with personal communications have indicated that applying glycerin-based gel sheets to stalled wounds, some 15-20-year-old chronic wounds, resulted in healing in 1-20 weeks (data/case studies on file).
Indications for use: Elasto-Gel™ has been approved for all types of wounds, that is, pressure ulcers, acute and chronic wounds, diabetic wounds, traumatic wounds, dermatology wounds, cancer tumors, and first- and second-degree burns, to name a few. Because of the product's features and benefits, it may be used on a variety of wounds. Because of its padding properties, it may be also used as a preventative product over bony prominence areas so that wounds do not occur. The glycerin properties act as a skin substitute and may also be used for scar reduction.
Caution: Elasto-Gel™ is not approved for third-degree burns as no dressing has been approved by the FDA for this type of wound.
