RT Journal Article SR Electronic T1 Local applications to wounds – II: dressings for wounds and ulcers JF Drug and Therapeutics Bulletin JO Drug Ther Bull FD BMJ Publishing Group Ltd SP 97 OP 100 DO 10.1136/dtb.29.25.97 VO 29 IS 25 YR 1991 UL http://dtb.bmj.com/content/29/25/97.abstract AB Pharmaceutical products for wounds1 are hardly ever applied alone, and dressings are at least as important for healing.2 An ideal dressing protects the wound physically, keeps it warm and moist, assists the removal of exudate and dead tissue, encourages healing and reduces the likelihood of infection. Different types of wound require different types of dressing (see box). Physical and physico-chemical properties are much more important than chemical reactivity. Common policies are needed for the use of wound dressings in hospital and in the community.
