In the management of first and second @-@ degree burns , little quality evidence exist to determine which dressing type to use . It is reasonable to manage first @-@ degree burn without dressings . While topical antibiotics are often recommended , there is little evidence to support their use . Silver sulfadiazine ( a type of antibiotic ) is not recommended as it potentially prolong healing time . There is insufficient evidence to support the use of dressings containing silver or negative @-@ pressure wound therapy .
