-
5 signs of inflammation
- redness
- swelling
- heat
- pain
- loss of function
-
3 phases of the healing process
- Inflammation response
- Fibroblastic repair
- Maturation-remodeling
-
Inflammatory response phase
- vascular reaction: involve vascular spasm, formation of platelet plug, blood coaugulation, growth of fibrous tissue
- seen in first 3-4 days after injury
-
histamine
- first chemical to appear in inflammation
- major producer of arterial dialation and capillary permeability
-
seratonin
powerful vasoconstrictor
-
bradykinin
increase permeability and cause pain
-
heparin
- give off to temperature
- prevent blood coaugulation
-
prostaglandins
inflammatory process involvment
-
leukotrienes
- alter capillary permeability
- involved in inflammatory process
-
What chemicals are produced during early stages of inflammation?
prostaglandins and leukotrienes
-
Go over Injury Cycle
Go over Injury Cycle!
-
Fibroblastic repair phase
- repair-healing-inflammatory phase
- 48 hrs-72 hrs- 6 weeks
- regeneration-restoration of destroyed or lost tissue
-
primary healing
- during fibroblastic repair phase
- healing by first intention
- takes place in injury (cut)
-
secondary healing
- during fibroblastic repair phase
- healing by second intention
- results where large tissue lost
- scar tissue replaces area (lacerations)
-
Maturation-remodeling phase
- long term process
- remodel of fibers that make up scar tissue occurs according to tensile forces
- first 3-6 weeks characterized by increased production of scar tissue
- strength of scar tissue continues from 3 months to 2 years after injury
-
chronic inflammation
- inflammation reaction lasting months or even years
- occurs from repeated micro-traumas and overuse
-
cartilage healing
- limited healing capacity
- slow, little or no direct blood supply
-
ligament healing
- important for proper immediate and follow-up care
- goes through acute, repair, and remoded phases
- takes up to 12 months
-
healing of skeletal muscle
- regeneration of new myofibers is minimal
- active contraction of the muscle is critical to regain strength
- strains may last 6-8 weeks
-
nerve healing
- nerve cells cannot regenerate after death
- can take place within nerve fiber
- age and health play role
-
Time for bone healing is based on?
- severity and site of fracture
- extensive trauma
- age of patient
-
pain sources
- cutaneous pain-usually sharp, bright and burning, fast or slow onset
- deep somatic pain- tendons, muscles, joints
- visceral pain- from internal organs
- psychogenic pain- caused by emotion
-
acute vs chronic
- acute- designed to help protect body
- chronic- serves no useful purpose
