ANATOMICAL DISSECTION I Flashcards
dissection should occur where for incision placement?
center without tension on either end of the incision
how does skin heal?
side to side not end to end
make the incisions long enough
what is the purpose of the skin scribe?
plans all excisions and maps the excision of redundant tissue
how can incisions be marked?
defat the skin with alcohol and use hash marks before the prep
T/F, incisions over boney prominences may lead to a painful scar due to tension unless the prominence is removed?
T
can we operate through infected skin?
try to avoid it
considerations for skin incisions?
skin lines
weight bearing
blood supply
venous and lymphatic drainage
these represent the pattern of tension in the skin from muscle and underlying structures running at right angles to the muscle fibers?
skin tension lines
what is the effect of incisions perpendicular to the RSTLs?
gap apart as the incision is subjected to tension
for ideal scars, how should incisions run?
parallel to RSTLs
how are longitudinal incisions on the plantar aspect of the foot viewed?
bad, they violate the principles of RSTLs and are prone to form hypertrophic scars
what are the factors that influence the making of an incision?
stabilization of mobile skin sharpness of scalpel thickness of skin evenly applied pressure on the scalpel one clean stroke
multiple strokes of the scalpel through the skin incision causes?
islands of tissue causing necrosis and decreases the body’s defense mechanisms
how are incisions made?
perpendicular to the skin and not oblique for optimum healing and minimal scarring
what is the correct position of the scalpel to the skin?
scalpel to the skin is at a right angle and belly of the blade used to make the incision
