Q

What are the three different types of cleansing agents that can be used on wounds?

A

Wipes - cleansing only (non-medicated)
- saline impregnated (no sting, no disinfection)

Wipes - cleansing and disinfection (medicated)
- alcohol and/or chlorhexidine (alcohol free)

Sprays

  • low viscosity solutions, run off
  • little cleansing action but contactless
17
Q

What is a rubifacient?

A

A substance for topical application that produces redness of the skin, e.g. by causing dilation of the capillaries and an increase in blood circulation

18
Q

Describe Germolene

A

A thick antiseptic cream with a distinctive pink colour and scented with oil of wintergreen (methyl nicotinate)

19
Q

What are the properties of Germolene?

A

Combines an antiseptic action to help prevent infections, plus a soothing local anaesthetic effect of phenol to numb pain

20
Q

What is Germolene used to treat?

A
  • minor cuts and grazes
  • minor burns
  • scalds and blisters
  • stings and insect bites
  • spots
  • chapped or rough skin
21
Q

Describe Savlon

A

Smooth, white, homogenous cream

  • chlorhexidine digluconate 0.1% w/w
  • cetrimide 0.5% (antibacterial surfactant)
22
Q

Describe povidone iodine

A

A brown powder used a broad spectrum antiseptic for external application, in the treatment and prevention of infection in wounds

23
Q

Where is povidone iodine used?

A

Mainly in hospitals

24
Q

Which patient group should not use povidone iodine?

A

Thyroid patients

25
Q

Describe hydrogen peroxide

A

An oxidising agent and has broad-spectrum cidal efficacy (at 3%) but some doubt

26
Q

Which bacteria is hydrogen peroxide not effective against?

A

Certain aerobic bacteria, such as Staphylococci, have an enzyme (catalase) which breaks hydrogen peroxide down to water and oxygen, effectively diluting it

27
Q

What is Dettol comprised of?

A

Micellar 4.8% w/v chloroxylenol

28
Q

How should Dettol be diluted for antiseptic wound cleansing for cuts, grazes, bites and stings?

A

1 in 20

29
Q

What is TCP used to treat?

A

Mild antiseptic

  • topical wounds
  • sore throat
  • mouth ulcers
30
Q

How do wound dressings work?

A 
Create and maintain a moist environment
- provides optical conditions for wound healing
- increases rate of proliferation
Protects wound against impact
Keeps out microbes
Absorbs wound exudate
31
Q

What are the two types of wound exudate?

A

Early acellular exudate

Later cellular exudate

32
Q

Describe early accellular exudate

A

Clear, watery fluid that normally permeates skin tissue to provide oxygen and nutrients to the cells

33
Q

Describe later cellular exudate

A

Opaque, yellowy fluid.
