Inflammation Phase of Healing

What Happens to the Tissue:
- External and internal injury result in tissue death and cell death
- Decreased oxygen to area increases cell death
- Phagocytosis will add to cell death due to excess digestive enzymes
- First hour
- Vasoconstriction and coagulation occur to seal blood vessels and chemical mediators are released
- Immediately followed by vasodilatation of blood vessels
- Second hour
- Vasodilatation decreases blood flow, increased blood viscosity resulting in edema (swelling)
- Exudates increases (high concentration of RBC’s) due to increased vessel permeability
- Permeability changes generally occur in capillary and venules
- Margination occurs causing leukocytes to fill the area and line endothelial walls
- Through diapedesis and chemotaxis leukocytes move to injured area
- Cellular response
- Mast cells (connective tissue cells) and leukocytes (basophils, monocytes, neutrophils) enter area
- Mast cells with heparin and histamine serve as first line of defense
- Basophils provide anticoagulant
- Neutrophils and monocytes are responsible for small and large particles undergoing phagocytosis – ingestion of debris and bacteria
- 4. Cellular mediation
- Histamine provided by platelets, mast cells and basophils to enhance permeability and arterial dilation
- Serotonin provides for vasoconstriction
- Bradykinin is a plasma protease that enhance permeability and causes pain.
- Heparin is provided by mast cells and basophils to prevent coagulation
- Leukotrienes and prostaglandins are located in cell membranes and develop through the arachadonic acid cascade
- Leukotrienes alter permeability
- Prostaglandin add and inhibit inflammation
- 5. Complimentary systems
- Enzymatic proteins that destroy bacteria and other cells through their impact on cell lysis
- 6. Bleeding and exudates
- Amount dependent on damage
- Initial stage: thromboplastin is formed
- Second stage: Prothrombin is converted to thrombin due to interaction with thromboplastin
- Third stage: thrombin changes from soluble fibrinogen to insoluble fibrin coagulating into a network localizing the injury
Tissue Damage Results In:
- Redness: Caused by dilation of arterioles/increased blood flow
- Heat: Increased chemical activity & increased blood flow to skin surface
- Swelling: Caused by accumulation of blood & damaged tissue cells
- Pain: Direct injury of nerve fibers, pressure of hematoma on n. endings
- Chemical irritants: – bradykinin, histamine, prostaglandin
- Loss of Function Increased pain/ swelling
Tissue Response:
- Vascular changes
- Vasoconstriction – immediately; decreased blood flow to area (approx. 5-10 mins.); platelet plug formed; blood coagulation; produces local anemia
- Vasodilation – increased blood flow; increased hydrostatic pressure in blood vessels ( capillary permeability, plasma proteins leak out; proteins attract H2O – edema)
- Cellular Changes – chemical reactions start immediately
- Protein presence – changes osmotic relationship between blood & adjacent tissues (Plasma protein Ô while interstitial fluid protein . H2O follows plasma proteins out of vessel resulting in edema!)
- Neutralizes/destroys offending agents, restricts tissue damage to the smallest possible tissue & prepares area for healing
Objectives in Inflammation Phase:
- Decrease Pain
- Reduce Swelling
- Reduce Muscle Spasm
Goal to Limit Swelling using R.I.C.E Principle:
- Rest
- Ice
- Compression
- Elevation are critical to limiting cell death
- 1. Restricted Activity (Rest)
- Healing immediately begins after injury
- Without rest, external stresses are still placed on the injured area, interfering with the healing process- prolonging recovery
- Controlled mobility is superior to immobilization
- 24-48 hours of rest should be applied prior to active rehabilitation – depends on severity
- 2. Protection & Ice
- Protect the injury from further damage
- Splint, wrap, immobilize the injured site depends on severity
- 3. Compression
- Single most important factor in swelling control
- Mechanically reduces space available for swelling accumulation
- Using an elastic wrap, firm, evenly applied pressure can be achieved
- Compression should be maintained continuously for 72 hours – depends on severity
- With chronic inflammatory conditions compression should be applied until the swelling is almost entirely gone
- 4. Elevation
- Used to eliminate the effects of gravity on blood pooling
- Assists venous and lymphatic drainage of blood and other fluids from the injured area
- Elevation should occur as often as possible during the first 72 hours of the acute injury – depends on severity
Treatment:
Phase I: Acute Inflammatory Phase
Initial swelling management & pain control are crucial
- R.I.C.E
- Chiropractic Adjustment
- Electrical Muscle Stimulation-Pulsed
- Ultrasound-Pulsed
- Passive Joint Motion
