Conclusions

Different types of chronic wounds have different requirements and therefore there cannot be one single dressing that addresses all the problems and issues associated with different types of wounds. Based on different wound etiologies, a variety of wound dressings with different structures and properties needs to be developed. In the case of donor site wounds the dressing needs to completely cover the nociceptors and nerve endings so they are not exposed to air and the external environment. By designing a future donor site wound dressing from suitable biomaterials and with an engineered structure that addresses the symptoms that cause pain, it is anticipated that not only can the level of pain sensation be reduced and/or eliminated among patients with donor site wounds, but that their rate of wound healing may be accelerated and the period of hospitalization may be reduced [15].
