BACKGROUND: This project used the process of research utilization to apply research knowledge to clinical practice for dressing peripheral intravenous (i.v.) catheters. METHOD: The project included (1) the review and synthesis of multiple research studies, (2) transformation of the research-based knowledge into a clinical protocol of use of adhesive bandage (AB) for dressing peripheral i.v. catheters, and (3) evaluation of the proportion of phlebitis as an outcome measure for comparison of peripheral i.v. catheter sites dressed with 2 x 2 inch gauze/tape or AB. Integral to the research utilization process was the use of planned change strategies. RESULTS: The proportion of phlebitis among peripheral i.v. catheters dressed with gauze/tape was 16.7% compared with 14.9% for AB. Antimicrobial ointment applied to the insertion site resulted in a higher proportion of phlebitis when used with an AB. CONCLUSION: This project used a research utilization framework to transfer research knowledge into clinical practice. To assure dissemination and implementation of the new practice, the use of ABs for dressing peripheral i.v.s was incorporated into hospital policy and procedure. In addition, the discontinuation of application of an antimicrobial ointment to peripheral i.v. sites was reinforced.

Elastic wrap bandaging is unreliable and dangerous in terms of pressure and pressure distribution (tourniquet effect). The Puddifoot dressing is safe and is less likely to produce a tourniquet effect. The range of pressures it produces is low--possibly too low to achieve ideal moulding or oedema control. A pneumatic bandage achieved a relatively narrow range of pressures between capillary and arteriolar blood pressures. It minimized tourniquet effects and differences between skilled and unskilled bandagers. It is sufficiently promising to merit development.
The use and aims of various wound dressings are discussed. Application and indications in the horse vary according to the type and location of the wound as well as the nature and availability of the dressing material. Coaptation and immobilization are essential to promote healing in certain locations. Techniques used for bandage application in horses are described, with special emphasis on problem areas.

OBJECTIVE: To evaluate healing of pinch-grafted wounds on the distal aspect of the limbs of ponies bandaged with equine amnion or a standard nonadherent wound dressing material. ANIMALS: 6 ponies. PROCEDURE: A 2.5x2.5-cm full-thickness section of skin was removed from the dorsal aspect of each limb at the midpoint of the metacarpus or metatarsus. Six days later, wounds were grafted with partial-thickness pinch grafts. Half the wounds were bandaged with amnion, and the other half were bandaged with a nonadherent dressing. Bandages were changed every 3 days until wound healing was complete. At each bandage change, numbers of grafts lost were recorded, and wounds were measured. RESULTS: Percentage of grafts lost from wounds bandaged with amnion was not significantly different from percentage lost from wounds bandaged with the nonadherent dressing. Median healing time for wounds bandaged with amnion (30 days) was significantly less than median healing time for wounds bandaged with the nonadherent dressing (39 days). All wounds were healed by day 45. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that amnion can be used for bandaging pinch-grafted wounds on the distal aspect of the limbs of ponies.

Dialdehyde cellulose (DAC) was prepared by periodate oxidation of various cellulosic materials in the form of sutures and bandages. The suitability of using DAC for making bioabsorbable sutures and antimicrobial wound dressing bandages was studied. The investigations indicated that DAC combines the requisite mechanical strength with an inherent antimicrobial nature. It was found that the oxidation of cellulose to yield DAC also rendered it bioabsorbable. The DAC was coated with different concentrations of urea formaldehyde in order to improve the mechanical properties for making sutures.
