39. WOUND CLEANSING :
The ideal wound cleansing solution :
• Non toxic to viable tissues.
• Effective in the presence of organic materials such as blood, slough or
necrotic tissues.
• Able to reduce the number of microorganism.
• Hypoallergenic and does not cause sensitivity reaction.
• Readily available, cost effective and stable.
40. WOUND CLEANSING SOLUTIONS:
1. Tap water- for home environment is acceptable.
2. Normal Saline 0.9%- is the safest cleansing agent because it does not interfere with wound healing.
3. Distilled water- for irrigation- out patient clinics.
4. Povidone-iodine- Effective against gram positive and negative bacteria and other organism.
5. Potassium Permanganate- is an oxidising agent with disinfectant, deodorizing and astringent properties.
6. Alcohol 70%- hard surface disinfection and skin antisepsis.
7. Dermacyn Solution- indicated for chronic wound, DFU, VU, post surgical and infected wound.
8. Chlorhexidine- antiseptic solution against gram positive and negative bacteria.

partial thickness burns. Useful in the removal of biofilm.
42. WOUND PRODUCTS:

blisters, retention of primary dressing not recommended with fragile skin and
infected wounds.
E.g. Tegadernm , Opsite
3. Hydrocolloids Dressing- contains hydrocolloid material (sodium
carboxymethycellulose-NaCMC and gelatin) that reacts with wound exudate
forming a gel like covering. Break down of the product my produce a residue
of varying colours and possible foul odour. E.g. Duoderm Extra Thin, Comfeel
Dressing
44. WOUND DRESSING PRODUCTS:

exudate, bacteria and necrotic material from the wound .Do not direct contact with
exposed bone or tendon or dry and low exudative cavity wounds. E.g. Mesalt

destruction of the hyper granulation tissue.
Treatment Options: Clean : Hypertonic impregnated gauze dressing or highly absorbent
foam. E.g. Mesalt , Biatain
Colonised/ Infected: Antimicrobial and highly absorbent dressing- E.g. Iodosorb powder,
mesalt ,Biatain Ag.

rehydration of necrotic tissue.
Treatment Options: Remove loosely detached slough tissue.
Superficial: Hydrocolloids or moist hydorfiber dressing: E.g. Comfeel. Duoderm
extra, Moistened Aquacel.
Cavity: Algisite or Hydrofiber/ Hydrogeland moisture retentive dressing: E.g.
Kaltostat, Aquacel,Duoderm gel and fil or foam dressing.

48. WOUND DRESSING MANAGEMENT:
Dry Slough- viscous yellow layer that is dry and sloughy adherent to wound bed.
Treatment Aims: To rehydrate adherent slough tissue and promote autolysis.
Treatment Options: Hydrocolloids or moist Hydrofiber dressing. E.g. Comfeel dressing/ Duo derm extra
thin, Duoderm gel.
Note: Film or foam as a secondary dressing when hydrogel is applied.
Other consideration: Take caution of skin maceration when hydrogel is applied to superficial or shallow
wound.
49. WOUND DRESSING
MANAGEMENT:
Necrotic / Eschar- necrosis is the death of a living tissue due to inadequate blood
supply. This tissue is often black/brown in colour and leathery in texture.
Treatment Aims: To rehydrate the eschar and reduce the risk of infection.
Treatment Options:Hydrocolloidsor hydrogel or combination of hydrogel and hydrocolloid dressing. E.g.
Comfeel , Duoderm extra thin and duoderm gel.
Note: Film or foam as a secondary dressing when hydrogel is applied
Other consideration: Do not rehydrate dry gangrene or ischaemic foot eschar.
50. WOUND DRESSING MANAGEMENT:
Necrotic (gangrene ) Digits- necrosis due to lack of blood supply to
foot/ toes.
Treatment Aims: To prevent infection and to aid in auto- amputation of digits
Treatment Option:
Dry gangrene: anti microbial cleansing and dry dressing or leave exposed. E.g. Methylated Spirit 70% or
Povidone Iodine 10%
Wet gangrene:Anti microbial and alginate dressing:E.g. Methylated Spirit 70% or Povidone Iodine
10%,Iodosorb powder + kaltostat dressing.
Other consideration: Do not apply retentive dressing E.g. Film or foam dressing, Seek vascular and
orthopaedic doctors opinion. Check for hypersensitivity to antimicrobial agents.
51. WOUND DRESSING MANAGEMENT:
Partial thickness burn- Scalded or fire burn involving dermal layers.
Treatment Aims: To prevent infection and to promote healing by maintaining a warm moist environment.
Treatment Option: Low and non adherent antimicrobial foam or wound contact of film dressing. E.g.
Urgotol Ag, mepilex Ag, Mepilex or Opsite Dressing.
Other consideration: Assess for history of hypersensitivity to antimicrobial agent.
52. WOUND DRESSING MANAGEMENT:

fungi that attaches firmly to a living or non living surface.
Treatment Aims: To reduce the biofilm and biofilm formation.
Treatment option: Regular debridement and antimicrobial dressing. E.g. Inadine ,
Urgotol Ag, Sesorb Ag, Iodosorb powder.
Note: Avoid moisture retentive dressing E.g. Fil or silicone foam.
Other consideration: Assess for history of hypersensitivity to antimicrobial agent.
53. WOUND DRESSING MANAGEMENT:
Critical colonised or Infected wound:
Critical colonization-multiplication of bacteria causing a delay in wound healing.
Infection- multiplication of bacteria causing disruption in wound healing and damage of wound tissue.
Treatment Aims: To reduce bio burden, treat infection manage exudate and odour.
Treatment option: Anti microbial dressing.
Superficial:Inadine, Iodosorb powder, Mesalt, Urgotol Ag, Aquacel Ag.
Cavity: Inadine, Iodosorb powder, Mesalt, Aquacel Ag, Seasorb Ag.
Other consideration: assess for history of hypersensitivity to antimicrobial agent. Refer to doctor when
there is spreading of inflammation or no improvement. Avoid moisture retentive dressing E.g. film and
foam.
54. WOUND DRESSING MANAGEMENT:
Friable tissue- Brittle or fragile tissue, easily damage agranular tissue that bleed easily
often indicate high bacterial load.

Treatment option: High Absorbent Anti microbial dressing. E.g.Mesalt, Iodosorb powder and mesalt,
Seasorb Ag
Note: Avoid moisture retentive dressing E.g. Fil or silicone foam.
Other consideration:Assess for history of hypersensitivity to antimicrobial agent. Refer to doctor when
there is spreading of inflammation or no improvement. Avoid moisture retentive dressing E.g. film and
foam.
55. WOUND DRESSING MANAGEMENT:
Granulation-during the proliferative phase of healing, this is the bright red tissue
formed from new capillary loops which are red moist and moist in appearance.
Treatment Aims: To promote and protect angiogenesis by maintaining a warm moist environment;.
Treatment Options:
Superficial:Low/ non adherent wound contact layer or foam dressing: E.g. Urgotul, Mepitel, Mepilex.
Shallow : Algisite or Hydrofiber or hydrogel dressing: E.g. Kaltostat, Aquacel, Duoderm gel
Cavity: Algisite or Hydrofiber dressing: E.g. Kaltostat , Aquacel.
Other consideration: Do not apply film dressing on moderate and heavy exudating wound.
56. WOUND DRESSING MANAGEMENT:
Epithelialisation-The final stage of wound healing where epidermal cells migrate
across the across the surface of the wound. These cells are pink/ white in colour at the wound edges or
over granulation tissues.
Treatment Aims: To protect and promote new tissues growth by maintaining a moist environment.
Treatment Options: Low/ non adherent wound contact layer or hydrocolloid: Urgotul, Mepilex, Mepilex lite,
Melolin, Duoderm Extra thin.
Other consideration: New form Tissue is only 60-80% as strong as origin. Failure to protect may result in
reopening of wound.
