Unlabelled:
Wound dressings have been successfully explored for use in prevention of pressure ulcers in individuals who are at clinical high-risk for developing ulcers.
Methods:
In this study, application of a recently described body analog test fixture and method is used to evaluate performance features of 8 clinically available dressings for prophylaxis. Documenting dressing performance is essential to defining the proper use and limits to application of dressings for ulcer prevention. These in vitro studies were undertaken to characterize the impact on the microclimate generated by the application of a dressing to the surface of the skin.
Results:
The measurement of moisture trapped next to the skin, moisture escaped from the dressing, and heat trapped by the dressing show that some dressings are more suited for skin protection.
Conclusion:
It is evident that an optimal performance band for microclimate management exists in the application of dressings for prophylaxis, and that dressings should be evaluated for proper performance prior to implementation in a pressure ulcer prevention program. .
