HEALING

It's the final stage of the response of tissue to injury
Phases
- inflammatory
- proliferative
- remodeling
Depends on
- type of damaged tissue
- proliferative ability
- nature of disruption
Types
- primary
  - in clean incised wounds,good apposition of edges
    - surgical incisions
- Secondary
  - in open wounds, significant tissue loss
    - necrosis , infection
  - features
    - large gaps
      - more
        blood
        fibrin
        necrotic debris
        intense inflammatory reactions
    - patent contraction of size
      - due to myofibroblasts
    - scaring
      - due to granulation tissue
    - chronic inflammation
Complications
- contracture
  - thickening & shortening of collagen bundles
- proud flesh
  - excess formation
- keloid
  - thick interlacing bundles
    - swelling
Systematic Effects
- nutrition
- metabolic status
- circulatory status
- hormones
Local Effects
- infection
- mechanical factors
- foreign bodies
- wound size
- wound type
- wound location
Hemorrhage
- arterial
  - spurting blood
  - pulsating flow
  - bright red color
- venous
  - steady slow flow
  - dark red color
- capillary
  - slow even flow
skin wound classifications
- friction blister

- laceration
- avulsion
- incision
- puncture
- amputation
- crush injury
skin
- largest organ
- protective function
- compasition
  - epidermis & stratum corneum
  - dermis
    - contains capillary network
  - subcutaneous layer
    - hypodermis
    - adipose layer
