Q

What is the trade name for chlorhexadine impregnated tulle gras?

A

Bactigrass

17
Q

What effect does NSAID have on wound healing?

A

Suppresses the inflammatory phase of healing by blocking prostaglandin synthesis

18
Q

What effect does cytotoxic agents have on wound healing?

A

Affects rapidly replicating cells primarily epithelialising cells

19
Q

What effect does corticosteroids have on wound healing?

A
  • Suppress macrophages and collagen production
  • impairs angiogenesis and epithelisation
  • inhibit wound contraction
  • lowers immune response
  • increase susceptibility to infection
20
Q

What effect does immunosuppressive drugs have on wound healing?

A

Reduce white cell activity resulting in impaired debris clearance

21
Q

What effect does antibiotics have on wound healing?

A
  • penicillin releases peniciliamine, preventing collagen cross-linking
  • doxycycline reduces matrix metalloproteases and retard collagen degradation
22
Q

What effect does nicotine have on wound healing?

A
  • Reduces neutrophils, collagen, connective tissue synthesis, macrophage function, epithelialisation and vitamin C stores
  • 6x increased risk of wound infection and dehiscence
23
Q

What is the criteria for standard aseptic technique?

A
  • Simple
  • Less then 20 min in duration
  • Involves small key parts and sites
  • Minimal number of key parts
24
Q

What is the criteria for surgical aseptic technique?

A
  • Complex
  • Longer then 20 min
  • Large open key site
  • Large/numerous key parts
25
Q

Define primary intention mode of healing

A

Wound edges held in close apposition by either sutures, staples, adhesive taps or tissue glue.

26
Q

Define delayed primary intention as a mode of healing

A

Infected wound that requires intensive cleaning prior to primary closure 3-7days

27
Q

Define secondary intention as a mode of wound healing

A

Spontaneous wound healing occurs by an obvious process of granulation, contraction and epithelisation that results in scarring

28
Q

Define what the 4 types of exudate indicate

A
  • Serous: clear straw coloured
  • Haemoserous: slight blood stained serious fluid
  • Sanguineous: frank or heavily blood stained fluid
  • Purulent: containing pus
29
Q

What do rolled wound edges indicate?

A

Inhibit healing & epithelisation of sinus tracks or malignant changes

30
Q

What do raised wound edges indicate?

A

Hypergrannulation or malignancy

31
Q

What aspects of surroundings skin need to be assessed?

A 
Cellulitis
Oedema
Induration
Eczema
Maceration 
Foreign bodies
Contact dermatitis
32
Q

What does pain indicate?

A 
Disease process
Trauma
Surgery
Infection
Foreign bodies
Poor dressing choice or products
33
Q

What effect can infection have on a wound?

A

Dehiscence
Evisceration
Haemorrhage
Sepsis

34
Q

What are 6 other signs of infection?

A

New, increased and altered pain
Delayed healing
Friable, bright red Hypergrannulation tissue
