How do surgical wounds usually heal? a. primary intention closure b. second intention wound healing c. secondary closure d. delayed primary closure

Primary intention-  wound healing with skin edges that are approximated, risk of infection is low, healing occurs quickly with minimal scar formation as long as infection and secondary breakdown is prevented (similar to a surgical wound)   Most common = Acute wounds; minimal tissue loss = surgical wounds and superficial partial thickness (abrasions/blisters)

Secondary Intention  This type of healing is in wounds with extensive tissue loss/infection & wounds in which the edges cannot be approximated (closed).  Would is left open and granulation tissue gradually fills in the deficit. Susceptible to infection. Wet to dry dressings. Ex: Pressure Ulcer  Associated w/ pathology = diabetes, ischemia, pressure damage in inflammation  (Neuropathic, arterial, venous, full thickness, chronic inflammation)  Require ongoing wound care - larger scares

answer(b) keep oxygenated and deoxygenated blood separate;
