Approches used in open wounds are moist and wet-to-dry techniques. These are not mutually exclusive; often both are used during the course of healing. Some experts are proponents of using moist technique throughout healing; others support their use only in clean, noncontaminated wounds to prevent infection. As there is no veterinary research to end the debate, practice is based on preferences and human research findings. Exudate levels and the needs of the wound should be assessed at each bandage change to ensure that the proper dressing is selected for the next bandage.
