L2 - Tissue Healing & Pain Flashcards
acute or chronic in nature
primary injury
physiologic response of tissue following trauma
healing process
primary injury that produces immediate pain and disability
macrotrauma
more chronic in nature injury that is from overuse and result from repetitive loading or incorrect mechanics from normal or abnormal loads
microtrauma
a destructive and self propagating biological change in cells and tissues that leads to their dysfunction or death over hours to weeks after the primary injury
secondary injury
a protective response by an organism to remove the irritating stimulus and initiate the healing process
inflammation
5 clinical signs of inflammation
heat (calor), redness (rubor), swelling (tumor), pain (dolor), loss of function
three phases of healing
inflammatory, proliferation, maturation
inflammatory phase is usually about blank long
0-6 days
proliferation phases usually spans from about blank to blank
day 3 - day 20
proliferation phase purpose is to cover the wound and impart blank to the blank
strength, injury site
injured site has the greatest amount of blank but the blank strength of tissues can be as low as blank percent of normal tissue
collagen, tensile, 15
initial collagen that is laid down is not oriented like the original blank, but eventually it blank
tissue, matures
signs and symptoms of blank subside during proliferation phase
inflammation
maturation phase usually goes from about blank to blank
day 20 - year 3
purpose of maturation phase is blank or remodeling of the blank fibers that make up the scar tissue
realignment, collagen
there are blank signs of inflammation during maturation phase
no
maturation phase may be accompanied by blank that limit motion
adhesions
in maturation phase, pain is felt only with blank usually
passive overpressure
tissues respond to the demands placed upon them causing remodeling or realignment of fibers along lines of tensile force
wolff’s law
three factors that impact rate of healing
edema, hemorrhage, blood supply, muscle spasm, atrophy, infection, age
an unpleaseant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage
pain
pain is subjective and acts as a blank mechanism to protect against blank
warning, injury
pain experienced after injury has taken place and tissue damage is occurring
acute
