3. Pain
4. Exudate
5. Heat

13

What two products have anti-inflammatory properties?

1. Silver
2. Iodine

14

What two products have haemostatic properties?

1. Calcium Alginate
2. Honey

15

What product can NOT be used on a bleeding wound?

Hypertonic Sodium Chloride

16

What is the trade name for chlorhexadine impregnated tulle gras?

Bactigrass

17

What effect does NSAID have on wound healing?

Suppresses the inflammatory phase of healing by blocking prostaglandin synthesis

18

What effect does cytotoxic agents have on wound healing?

Affects rapidly replicating cells primarily epithelialising cells

19

What effect does corticosteroids have on wound healing?

-Suppress macrophages and collagen production
- impairs angiogenesis and epithelisation
- inhibit wound contraction
- lowers immune response
- increase susceptibility to infection

20

What effect does immunosuppressive drugs have on wound healing?

Reduce white cell activity resulting in impaired debris clearance

21

What effect does antibiotics have on wound healing?

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

22

What effect does nicotine have on wound healing?

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

23

What is the criteria for standard aseptic technique?

- Simple
- Less then 20 min in duration
- Involves small key parts and sites
- Minimal number of key parts

24

What is the criteria for surgical aseptic technique?

- Complex
- Longer then 20 min
- Large open key site
- Large/numerous key parts

25

Define primary intention mode of healing

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

26

Define delayed primary intention as a mode of healing

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

27

Define secondary intention as a mode of wound healing

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

28

Define what the 4 types of exudate indicate

- Serous: clear straw coloured
- Haemoserous: slight blood stained serious fluid
- Sanguineous: frank or heavily blood stained fluid
- Purulent: containing pus

29

What do rolled wound edges indicate?

Inhibit healing & epithelisation of sinus tracks or malignant changes

30

What do raised wound edges indicate?

Hypergrannulation or malignancy
