According to Nancy Morgan, RN, at Wound Care Advisor, hydrocolloid dressings, such as Duoderm, need to be changed every three to seven days, depending on the amount of seepage from the wound. Duoderm Signal dressing contains a green line that indicates when the dressing needs to be changed.
Duoderm dressings are indicated for use with wounds such as diabetic ulcers, leg ulcers, pressure sores, post-operative surgical wounds, second-degree burns and wounds that result from injury. The tapered edge of Duoderm dressing contours around difficult body areas such as the heel. These dressings should be used under the supervision of a health care professional, according to Wound Care Advisor.
