Wound dressings: principles and practice

Wound dressings have increased in efficacy and number as the scientific understanding of wound healing has improved. However current practice is governed by expert opinion as high-quality studies comparing the effectiveness of different dressings are lacking. Surgeons are regularly involved in wound management, therefore require a good understanding of the properties and uses of different wound dressings. By having a firm grasp of the pathophysiology that underlies the wound-healing process a surgeon can make informed decisions about how best to manage a patient. An overview of optimal conditions for healing and the assessment of wounds is provided here. Dressings and their modes of action are discussed to provide guidance for their use in different wounds.
