Mepilex Ag Versus Silver Sulfadiazine in Children and Adults With Burn Injuries.

Subjects enrolled in this investigation were in-patients at eleven centers in China. To be included, subjects had to have deep partial-thickness burn injuries. The subjects were consecutively allocated to a subject code providing they fulfilled all inclusion criteria and none of the exclusion criteria and had signed a written informed consent form. Two evaluators independent of each other made the judgment regarding depth of the burn before enrolling a subject. The subjects were randomized to either receive Mepilex Ag or SSD.

Treatment period were up to four weeks with either SSD or Mepilex Ag. Changes of the investigation products were performed according to a standardized schedule, unless the wound healed before.
