About

Pressure ulcers, also known as decubitus ulcers or bedsores, are localized injuries to the skin and underlying tissue resulting from prolonged pressure. Management of pressure sores is crucial due to their association with increased morbidity, healthcare costs, and reduced quality of life. This study aims to evaluate the efficacy of two treatment modalities: Type-I Collagen-based Skin Substitute (HPTC) vs. Dehydrated Human Amnion/Chorion Membrane (dHCAM)

Full description

Pressure ulcers, also known as decubitus ulcers or bedsores, are localized injuries to the skin and underlying tissue resulting from prolonged pressure. They are prevalent in individuals with limited mobility, such as the elderly and those with spinal cord injuries, particularly in long-term care settings. Effective management of pressure ulcers is crucial to prevent complications and improve patient outcomes, includes pressure relief, wound care, and advanced therapies such as bioengineered skin substitutes. Management of pressure sores is crucial due to their association with increased morbidity, healthcare costs, and reduced quality of life. This study aims to evaluate the efficacy of two treatment modalities: Type-I Collagen-based Skin Substitute (HPTC) vs. Dehydrated Human Amnion/Chorion Membrane (dHCAM) in promoting the healing of pressure ulcers. While both products are used in wound management, direct comparative studies evaluating their efficacy in treating pressure ulcers are limited.
