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].
