PHTY300 Lecture Notes - Lecture 9: Proprioception, Cellulitis, Intubation
Document Summary
Anatomy of the skin: epidermis, superficial protective layer, keratin which toughens and waterproofs, melanin (melanocytes) for uv protection, rete pegs for attachment /adherence to dermis. Impaired temperature control: access point for infection. Loss of moist environment for muscles, tendons and nerves. Wound closure - wound closure spontaneously in 7 - 10 days: partial thickness burn (dermal burn) Areas destroyed - epidermis and superficial part of dermis. Appearance - red to pink appearance, blistered. Blanching and capillary return - rapid capillary return / blanching. Wound closure - wound closure spontaneously in 14 days: superficial partial thickness or superficial dermal burn, deep partial thickness or deep dermal burn. Areas destroyed - epidermis and deeper into the dermis. Appearance - creamy moist white appearance, pseudomembrane may be present, oedematous. Sensation - sensation intact but may have decreased sensation to light touch in some areas (some nerve endings damaged) Blanching and capillary return - delayed capillary return / blanching but present.
