Foreword
As with any clinical guideline, recommendations may not be appropriate for use in allcircumstances. A limitation of a guideline is that it simplifies clinical decision-making.
1Decisions to
adopt any particular recommendation must be made by the practitioner in the light of:
Available resources Local services, policies and protocols
The patients circumstances and wishes
Available personnel and devices
Clinical experience of the practitioner
Knowledge of more recent research findings.

1. INTODUCTION AND SCOPE OF GUIDELINE
1.1 Purpose of the Wound Guideline
1.1.1 The purpose of this guideline is to provide guidance within SEPT WestEssex Locality regarding the management of acute and chronic wounds.
1.1.2 This guideline aims to simplify the decision making regarding woundmanagement while ensuring that patients are provided with the bestevidence based care. To that end this guideline must be used to ensurethat all patients have been assessed and managed holistically and thatcare is supported with completed care plans and assessments inconjunction with the following guidelines:
SEPT West Essex Locality Infection Control Guidelines
SEPT West Essex Locality Pressure Ulcer Prevention andManagement Guidelines.
SEPT West Essex Locality Dressing Formulary Guidelines
Nursing and Midwifery Council (NMC) The Code: Standards ofconduct, performance and ethics for nurses and midwives.

2. PROCESS OF HEALING4
Wound healing is a continuous process, however four stages can be identified. The length ofeach phase varies with the nature of the wound and the patients general condition.
STAGE PROCESS CLINICAL EFFECTS IMPLICATIONS

2.1 Healing by First Intention(Acute Wounds)
Definition: Surgical or traumatic wounds where the edges are brought together bysuturing, steristrips, clip, staples or glue.
Acute wounds usually follow a well-defined process as illustrated in Table 1. Thesestages overlap and the entire wound-healing process can take several months.
Blood and exudate from a surgical wound is usually minimal. Within 48 hours the woundwill have formed a natural barrier against invasion by pathogenic bacteria.
78
Surgical wounds, which are dry, can be left exposed after 48 hours following surgery.The preference of individual surgeons is likely to vary and staff should adhere to thewritten instruction within the patients notes.
2.2 Healing by Second Intention 9(Chronic wounds)
Definition: All open wounds e.g. pressure ulcers, dehisced surgical wounds, legulcers. (These guidelines do not cover the management of Leg Ulceration. Please referto the Leg Ulcer Guidelines)
In the past, the acute wound-healing model has been applied to chronic wounds, but it isnow known that chronic wound healing is different from acute wound healing.
10Chronic
wounds become stuck in the inflammatory and proliferative phases of healing, delayinghealing.
11 The epidermis fails to migrate across the wound tissue and there is
hyperproliferation at the wound margins, which interferes with normal cellular migrationover the wound bed.
12 In chronic wounds there appears to be an overproduction of
matrix modules resulting from underlying cellular dysfunction and disregulation.13
Fibrinogen and fibrin are also common in chronic wounds and it is thought that these andother macromolecules scavenge growth factors and other molecules involved inpromoting wound repair.
14 So, while there may be large number of growth factors within
the wound, these can become trapped and therefore unavailable to the wound repairprocess. Chronic wound fluid is also bio chemically distinct from acute wound fluid; itslows down, or even blocks the proliferation of cells such as keritinocytes, fibroblasts andendothelial cells, which are essential for the wound-healing process.
1516
For these reasons chronic wounds must be viewed differently than acute wounds. Thereis often a complex mix of local and host factors, which need to be assessed and treated.

2.3 Wound Bed Preparation
Wound Bed Preparation (WBP) is a well established concept and the TIME framework is apractical tool to assist practitioners when assessing and managing patients with wounds.
171819
Itis however important to remember to assess the whole patient.
20
21 WBP is a way of focusing
systematically on most of the critical components of the non-healing wound to identify the possiblecause of the problem.
WBP involves the application of the principles of Tissue, Infection, Moisture and Edge (TIME) to awound bed in order to enable the practioner to make a systematic interpretation of the observablecharacteristics of a wound and to decide on the most appropriate intervention.The TIME Table (Table 2) illustrates in a simple way the link between clinical observations and theunderlying cellular abnormalities, and the effects of clinical interventions at a cellular level. The firstcolumn lists the clinical signs of a non-healing wound. As growth factors, senescent cells orfibroblasts cannot be seen with the naked eye; the clinician needs clear, visible signs that can beassessed at the bedside. The second column highlights the proposed pathophysiology of thatclinical observation. Column three and four suggest the clinical actions that need to be taken andthe effects of these actions. The final column is for clinical outcomes, which are objective and
measurable.22

2.3.1 Tissue
Monitoring the type of tissue in a wound is the mainstay of wound assessment in clinicalpractice, recording the presence of necrosis, slough, granulation tissue or epithelialium.
24
This helps predict the wounds position in the healing continuum. The presence of non-viable tissue is a significant clinical observation as it can be responsible for delayedhealing.
25It is described as necrotic, sloughy, devitalised or dead tissue. Necrotic tissue
consists of dead cells and debris, while slough or fibrinous material consists of fibrin, pus
and proteinaceous material. Necrotic tissue is usually black or brown in colour and soft orliquefying in consistency. If necrotic tissue dries out, and is hard and leathery it is morecommonly described as eschar.
26Necrotic tissue when grouped with the clinical problems
of excess exudate and bacteria within dead tissue is termed necrotic burden.27
Sloughmay be creamy in appearance because of large amounts of leukocytes present.
28
Alternatively, a tendon may be exposed, signifying wound deterioration, presenting asstriated, yellow tissue. The wound may be shiny, suggesting the presence of biofilms sophisticated coatings often resistant to antimicrobials.
29 If granulation tissue is friable,
unstable to touch and bleeds easily it may be infected.30
The practioner should be able todifferentiate between healthy and unhealthy tissue.
31(See Table 3)
The surface or the texture of tissue can yield useful clues, for example if granulationtissue is fleshy and exuberant, it may be hyper granulating (overgranulating) and thus
stuck in the proliferative stage of healing. It is suggested that healthy granulation tissuehas rosettes on the surface.
32
Hyper granulating tissue is thought to arise from an extended inflammatory response.There is of course a danger that tissue could be treated as hyper granulation when it is infact a carcinoma.
33
34 If concerned staff should refer the patient to the medical staff
responsible for the patients care.

All wounds contain micro-organisms, yet the majority are not infected. Infection in awound causes pain and discomfort, delays healing and can be life threatening.
36 The
European Wound Management Association Algorithm illustrated in Figure 1 illustrates thedifferent stages of wound infection. The spectrum of interaction between the microbialcommunity and host may gradually reach a point at which wound healing process isimpaired or localised detrimental host effects are initiated.
37 Bacteria involvement in
wounds can be divided into four categories:
Contamination
Colonisation
Critical colonisation
Wound infection.
Wound contamination is the presence of non-multiplying bacteria in a wound.38
Woundcolonisation is the presence of replicating micro organisms adhering to the wound withouta host reaction. If mixtures of potential pathogens are multiplying, this may lead to a delayin wound healing and the critical colonisation stage is reached.
3940
41
Unsuppressed, thenatural progression from this stage is to wound infection. This is when the sum of thebacterial load and the virulence factors the bacteria produce is greater than the hosts
immune defences, resulting in harm to the host.42
Biofilms are communities of microbial cells, attached to surfaces and encased in a slime.Research has shown that biofilms may be totally unperturbed by activatedmacrophages, neutrophils, antibodies, complemented or other host defences.
43 This
offers protection against phagocytosis, antibiotics and antimicrobial agents.44
45
Microbial involvement in delayed healing must be suspected when other causes havebeen eliminated.
4647
48
Antimicrobials are agents that either kill or inhibit the growth anddivision of micro-organisms.
49
50 They include antibiotics (which act on specific cellular
target sites), antiseptics, disinfectants and other agents (which act on multiple cellulartarget sites).
51 Chronic wounds do not always display the classic signs of infection;
therefore other criteria need to be taken into account. (Table 4)

When bacteria proliferate they form micro colonies that become attached to the woundbed and secrete glycocalyx or biofilms that help to protect the microorganism from anti
microbial agents and can delay healing.52
53
The diagnosis of infection is primarily a clinical skill based on careful history taking andclinical observation, with microbiological data used to supplement the clinical diagnosis.Quantification of bacteria by wound biopsy has been considered the gold standard, butsurface sampling cost less and is easier to carry out.
54 The European Wound
Management Association Algorithm for Managing Wound Infection as illustrated in Figure1
55 should be used to assist in clinical decision making regarding the diagnosis and
management of suspected infection.
Wound cleansing is an important factor in reducing bacterial burden. Organisms arephysically removed by irrigation with saline. Increasing the frequency of dressing changesmay also be useful particularly as infected wounds often produce copious amounts of
exudate, which may promote bacterial growth causing further tissue breakdown andmaceration of the surrounding skin. There is clearly a need to link the I element of WBPto the M element for intervention to be successful.

MRSA
MRSA stands for meticillin-resistant Staphylococcus aureus. It is sometimes known as asuper bug. There are various subtypes (strains) of S. aureusand some strains areclassed as MRSA. MRSA strains are very similar to any other strain of S.aureus. That is,some healthy people are carriers and some people develop the types of infectionsdescribed above.
Most S. aureusinfections can be treated with commonly used antibiotics. However MRSA
infections are resistant to an antibiotic called meticillin and also to many other types ofantibiotics. MRSA strains of bacteria are no more aggressive or infectious than otherstrains of S. aureus. However, infections are much more difficult to treat because manyantibiotics do not work against MRSA. Infections with MRSA can sometimes becomemore severe than they may otherwise have been if the cause of the MRSA infection is not

diagnosed early and antibiotics that are not effective are given at first.57
For this reason itis vital that all MRSA positive wounds are referred to either Tissue Viability, Leg UlcerServices or Podiatry as appropriate within 72 hours of diagnosis.
Antibacterial strategy
The decision of whether to use antibiotics or antimicrobial products is a complex matter thatmust be based on the clinical findings of an experienced clinician. Figure 1 provides EWMAguidance on this matter.
58 Ideally systemic antibiotics are not recommended for wounds that
only show signs of local infection.59
Topical antiseptic agents whether antibiotic or antisepticsdelivered from a sustained-release dressing formulation therefore represent the first linetreatment, as they provide a high antimicrobial concentration at the site of infection.
60 Some
iodine and silver preparations have bactericidal effects even against multiple resistantorganisms such as MRSA.
6162
Topical antiseptics have the additional advantage that they donot interfere with the remainder of the protective bacterial flora in other parts of the body andare also less likely to produce an allergic reaction.
In the case of biofilms the mainstay is frequent removal of the wound surface either withsharp or surgical debridement. At present the effective treatment of medical biofilms is its
physical removal.
63
64
The early biofilm that re-emerges after debridement needs to besuppressed with multiple strategies. This will include wound cleansers, topical antimicrobialsand advanced primary dressings. Since biofilms adapt to selective stresses a rotating regimeof selective antiseptics such as silver or iodine is recommended.
65
Lack of a noticeable healing response within 2 weeks may necessitate the use of other topicalor systemic agents. Given the evidence that improvements in wound healing have previouslybeen associated with the elimination of malodour-causing anaerobes and that mixedanaerobes appear to play some synergistic role in preventing wound healing, the use of ametronidazole gel may then be considered
66under the instruction of the TVS.
Topical antimicrobials are most appropriate when used to decrease the bacterial burden inchronic wounds with active but localised infection. They are not solely suitable for highly
infected wounds with soft tissue invasion or systemic sepsis and should not be used as asubstitute for debridement or systemic antibotics. Increased antimicrobial resistance meansthese agents should not be used for an extended period of time and should be followed by anappropriate dressing once the bacterial burden has been reduced. Where infection hasextended beyond the level that can be managed by local therapy, systemic antibiotics shouldbe used in conjunction with antimicrobial products.

2.3.3 Moisture67
68
Exudate.Exudate contains a variety of substances including water, electrolytes, nutrients,inflammatory mediators, white cells, protein-digesting enzymes (eg matrixmetalloproteinases MMPs), growth factors and waste products. In the healing woundexudate appears to promote healing in a number of ways, including cell proliferation.MMPs which breakdown the cell-supporting matrix, are present mainly in inactive form. In
wounds not healing (Chronic wounds) exudate appears to have the opposite effects. Theexudate contains elevated levels of inflammatory mediators and activated MMPs.
69
One of the most significant challenges faced by nurses is the efficient and cost effectivemanagement of excessive wound exudates which causes extreme distress and negativelyimpacts on patients and carers quality of life.
70 The goal of effective wound management
is to remove excess moisture, debris and chemicals from the wound, while maintainingthe ideal moisture balance to allow cell migration and ultimately wound healing.
71 Poor
exudate management can either cause the wound bed to become too dry or too wet, theresultant imbalance of moisture will cause tissue damage.
72 There are no validated
precise measurements for assessing exudate, so for progress of a wound to be monitoredit is preferable that the same nurse reassesses a wound in order to aid comparison withserial assessments. Colour and consistence are considered in Table 5 with someguidance on causes and how.
There are three main methods of managing exudate:
1. Use of absorbant dressings or dressing which allow evaporation of moisture.2. Counter pressure through compression3. Drainage systems, either wound management systems or topical negative
pressure (TNP)
2.3.4 Edges
In WBP, E stands for edges, which are non-advancing or undermining. When woundedges fail to migrate or undermining is present, the clinician needs to reassess the cause
and intervene using the TIME table. Epidermal edges that are failing to advance over timetowards closure are perhaps the clearest sign of all that a wound is failing to heal. Woundmeasurement provides baseline information while continuous measurement helps topredict healing and aids monitoring of treatment efficacy and evaluation.
73 Wounds
should be re-measured every four weeks.74
If the margin is undermined, this may be asign of critical colonisation or infection. The use of cytotoxic agents and cortiocosteroidscan totally mask all signs of local or systemic infection.
75 At a cellular level, lack of
epidermal migration could be owing to non-responsive wound cells and abnormalities inprotease activity, which degrade extra cellular matrix as soon as it is formed.

84
85
86
Table 6 lists the commonest.Figure 4 illustrates how such factors can be grouped into intrinsic and extrinsic factors andcan occur alongside each other. Thus some wounds can be exposed to multiple factors,which impede its progress at any one time.

Cachexia92
3.2 Diet
Adequate nutrition is essential to promote wound healing. A diet rich in carbohydrates,high in protein and moderate fat is essential. Vitamins and trace element supplementsshould also be provided to all patients with established wounds where deficiency is knownparticularly vitamins C, E and zinc.
93 However the decision to provide trace element
supplements should be done following a thorough nutritional assessment.94

If Nursing Staff are uncertain in specific situations they should discuss their concernsregarding the need to provide supplements with either the Dietician or Medical Staffresponsible for the patient.
3.2.1. Identification of Patients Risk
Nutritional assessment should be carried out in line with the MUST NutritionalAssessment Form. (Appendix 1)
3.3 Pain
Unresolved pain negatively affects wound healing and impacts on quality of life.110
111
112
A painful chronic wound can often indicate that there is something wrong.
113 Holistic
assessment using TIME should provide indicators as to possible causes of such pain.Pain at wound dressing-related procedures can be managed by a combination of accurateassessment, suitable dressing choices
114
115
116 skilled wound management and
individualised analgesia regimens.117
118
An initial assessment should be carried out by an experienced clinician
119 in partnership
with clinical staff able to prescribe the appropriate medication. Every patient with a woundshould have an individual pain management plan including regular ongoing assessment
which should be performed each time a dressingrelated procedure is carried out.120
Background pain in the wound and surrounding tissue, plus any new regional pain thatmay have developed should be assessed. The intensity should be rated, before, duringand after the procedure.
121122
This should be documented in the patient notes and a careplan developed to address the pain. The level of pain should also be recorded on thewound assessment chart using a recognised pain scale as illustrated in Figure 2 and 3

3.3.1 Using Opiates on wounds123
124
Topical opiates act centrally and peripherally and can be alternative or concurrent formsof pain control for wounds. Opiates can be used on viable and non-viable tissue.The effective analgesia dose is low (10mgs) with analgesia occuring within a few minutes.The duration of pain relief from one dose can last up to 2 days.
The opiate should be mixed with hydrogel carrier and apply directly to the woundA foam dressing can be used to secure the hydrogel. The effective dose concentration is10mgs morphine opiate to 1gram hydrogel. Application should be daily or as requiredbasis.There are minimum adverse effects however it is preferable to keep certain wounds suchas ischaemic gangrene dry and thus the use of hydrogels would be contraindicated.

4. CLASIFICATION OF WOUND TISSUE
The Wound Healing Stage Classification as described below is recommended as itfacilitates simple and consistent verbal and written description of the appearance of thewound bed. This is a different classification to the pressure ulcer classification. (SeePressure Ulcer Guidelines)
4.1 Epithelialsing Tissue125
Appearance.
Translucent appearance, usually whitish-pink
Small islands of epithelial cells may be visible originating from the wound margin orreminents of hair follicles, sebaceous or sweat glands
The epithelial cells rapidly multiply and migrate across granulation tissue, until theyform a continuous layer. At this stage the wound will have smooth edges
4.2 Granulating Tissue126
127
Appearance:
Granular appearance, slightly uneven
Pinky-red colour (well vascularised) Healthy granulating tissue does not bleed easily
Granulating tissue which is dark in colour may signal ischaemia or infection
4.3 Sloughy Tissue128
Appearance:
Yellow/ white hue
May be dry or slimy
Adherent to wound bed (Slough forms when dead cells accumulate in the exudate,yellow colour due to the presence of a large number of leucocytes)
4.4 Infected Tissue
Appearance of Acute Wound Infection.
Inflammation
Localised heat and swelling around wound edge
Yellow/green pus
Offensive odour
Presence of green slough in wound
Pain
Increased exudate
Dark in colour
The presence of bacteria does not always indicate the presence of infection. Pus, odour
and slough are not always present in the infected wound. Systemic effects and a raisedbody temperature may be present. It is thus recommended that temperature, pulse, BPand respiratory observations are taken and recorded if there is suspicion of woundinfections.

4.5 Necrotic Tissue129
Appearance:
Black/Brown leathery appearance
Hard skin-like surface below which is a cavity full of dead tissue
Depth will not be known until the dead tissue is removed
4.6 Malignant (Fungating) Tissue
Appearance:
Raised irregular islands of malignant tissue
Often bleeds on contact
Characterised by very offensive odour due to colonisation by bacteria
It is acknowledged that no classification is likely to be wholly exhaustive; with this in mind itis important to complete a full assessment on a wound as directed on The Wound
Assessment Form (WAF) (Figure 5). If the wound is a pressure sore, it is also necessaryto state the grade (see Pressure Ulcer Guidelines)
5. WOUND ASSESSMENT.
Wounds need regular assessed if appropriate care is to be provided. Wound careproducts are designed to suit a wound at a particular stage of healing. As the woundchanges, dressing type may also need to be changed. It is important to use aclassification that all staff understand when assessing, planning and evaluating woundcare. This facilitates monitoring the progress and selecting appropriate wound careproducts.
130131
Wounds should be assessed using the principles of WBP and application of the acronymTIME illustrated in Table 2. Tissue observed should be classified according to the WoundTissue Classification described in Section 4. The Wound Assessment Form (Figure 5)
which incorporates the principles of WBP (TIME) should be completed at every dressingchange as documentation is as essential as the assessment itself.
132
The use of the WAF and a comprehensive care plan ensures that registered nurses arefulfilling their obligations under the NMC Standards for Records and Record Keeping.Failure to keep such records exposes the Nurse and the Trust to the risk of litigation. It iscrucial that wound assessment forms and care plans are completed on all patients whohave wounds. These records must be clearly written, signed and regularly updated.
133 An
entry must be made on the WAF following every dressing change.

6 WOUND CARE
A holistic assessment of the patient is essential before choosing a wound dressing.134
Acareplan should be drawn up using the information gathered in the WAF and directed by theTIME WBP Clinical Actions illustrated in the Timetable. (Table 2)Many wounds will be a combination of some of the already mentioned classifications identified insection 4. When this occurs each area would require different management however the most
serious state should be treated first.
6.1 Wounds Healing by First Intention
6.1.1 Uncomplicated Wound
EXAMPLES: Post surgical wounds/clipped wounds.Traumatic wound sutured/clipped/glued
PROBLEM: Potential risk of wound breakdown
GOALS: To prevent infection and promote first intention healing byproviding an optimal local environment
T: Promote viable granulation from the wound base
I: Reduce inflammation and maintain a bacterial balance
M: Achieve moisture balance
E: Measured advancing edges and base of wound.
CARE PLAN: Non adherent (N/A) dressing135
Analgesia to control pain.Should not require cleaning, if exudate is a problem it can beremoved by irrigating with sterile sodium chloride 0.9%Dressing: Wounds can be left exposed after 48 hours or coveredwith a semi-permeable film dressing.
136
6.2 Wounds Healing by Second Intention 137
6.2.1 Epithelialising Wound (Clean and Flat)
EXAMPLES: Any clean wound that has filled in with granulation tissue orsuperficial wounds where granulation tissue has been replacede.g. skin donor sites, superficial burn, and granulated pressureulcer.
PROBLEM: Break in normal integument. Pain from exposed nerve endings
GOALS: T: Promote epithelialsation
I: Reduce inflammation and maintain a bacterial balance.M: Achieve moisture balance
E: Measured advancing edges and base of wound.
CARE PLAN: Analgesia to control pain.Does not require cleaning if exudate is minimal. If cleaning isrequired use sterile sodium chloride 0.9%
Dressing: Minimal exudate Semi-permeable film

CARE PLAN: Local support, comfort and pain reduction. Control of bleeding
and odour are priorities as healing cannot be a goal. Early
identification of infection and reduction of odour will
considerably improve the quality of life for the patient.149
Understanding impact of the wound on the individual quality
of life and helping to ameliorate both physical and
psychological symptoms.150
Odour Control 151152
Establish the cause of the odour by sending a wound swab for microscopy andculture.Clean with sterile sodium chloride 0.9% if required.Dressing: Dress according to the classification of the wound.
Additional management: Antibacterial dressing, which includes charcoal or silvercan help to reduce odour.
153 Metronidazole gel can be used following a doctors
prescription.
Incipient Bleeding
Kalostat, an alginate dressing is a licensed haemostat and can help control
bleeding.154
Relief and Comfort
Foam sheets can be cut to fit a protruding wound and thus provide comfort andsupport.Small amounts of hydrogel can minimise adherence in dry wounds.Good provision of analgesia is crucial, particularly prior to dressing changes.
Exudate155
Foam sheets and high absorbency alginates should be used to control exudate.VAC therapy is contraindicated in malignant wounds.
6.4 Criteria for Removing/Changing Dressings
The wound should be assessed and the appropriate dressing applied in the followingevents.
wet contamination from external sources
strike through (when exudate has leaked through the dressing)
offensive smell156
pain or prolonged tenderness at wound site
unexplained pyrexia
inflammation at site
removal of drain/clips/sutures
allergic reactions.

The frequency of the dressing change will be influenced by the condition of the woundand dressing product used. (see manufacturers instructions)Frequent unnecessary changes should be avoided, as this will reduce thetemperature and humidity of the wound. It may also cause trauma to newly formedcells andmay permit colonisation of the wound by microganisms.
157
Dressing changes should be concluded promptly, adhering the aseptic principles asnecessary.
6.5 How To Take A Swab For Culture 158 159
Wound swabs should be taken when the wound presents with the signs of infection.160
(Figure 1and Table 4)
Cleanse the wound bed well with saline, bacteria are not washed away duringcleansing and thus can still be identified;
Do not swab eschar, exudate or pus;
Select the cleanest area of the wound;
First, dip the clean swab in the swab medium161
or sterile saline.162
Firmly press and rotate the swab in the cleanest area of the wound area, mover
the swab across the area in a ziz-zag motion from the centre to the outside. 163 Include tunnelling if present;
If pus is present take a separate sample of the fluid in a pot.
6.6 How to Treat Over-granulating Tissue164
165
166
167
Hypergranulation is normally transient resolving itself in time as the granulation tissue
contracts. Use of non-traumatic dressings to reduce hypergranulation should be the firstchoice. If overgranulation persists nurses should discuss the situation with the TVS or theresponsible physician to exclude undiagnosed malignancy as the underlying cause.
The reduction of hypergranulation/over-granulation may be achieved through the use ofthe following:
Foam Dressing; Lyofoam
Application of light pressure to the wound bed;if not contra-indicated is of benefit.
Silver Nitrate; (Sticks or .025% compresses); can be used however it is not a first linemeasure. Morison (1991) cited in Hampton S and Collins
168 found silver nitrate to be
caustic with potential to initiate methaemoglobinaemia and metabolic disturbance. Silvernitrate is therefore a treatment for very short-term use only.
Corticosteriod cream such as Elocon or Betnovate can be used under medical
supervision as a last resort and for very short-term use only. It should also beremembered that topical steroid preparations are not licienced for the treatment ofovergranulation and therefore responsibility for its use lies with the prescriber.

7 PRINCIPLES OF WOUND IRRIGATION172
173
The purpose of wound irrigation is to help create optimum local conditions of healing. Itshould remove wound debris. It should be performed in an atraumatic method, so thatepithelialising and granulation tissue is not damaged. The method used to do this shouldbe based upon an assessment of the wound and the patients general condition.
Clean epithelialising/granulating wounds do not benefit from mechanical irrigation, whichremoves exudate containing valuable healing factors. These wounds should be leftundisturbed for as long as possible to enhance the rate of healing. Wiping may damagenew granulation tissue. Chronic wounds with excess exudate may benefit fromirrigation.(See section 2.3.3)Irrigation using a syringe or by showering is often preferred providing that the pressureachieved is adequate to remove wound debris, but not damage healthy tissue.
When irrigation is not effective in removing remnants of the dressing (e.g. Hydrocolloids,Alginates) gentle wiping can be instituted. It is recommended that non-woven gauze (assupplied in dressing packs) be used in conjunction with either a gloved hand or forceptechnique.
Some methods of mechanical wound cleaning can result in the redistribution of bacteriarather than an actual reduction.
174 Care must be taken to wipe from clean areas to dirty
and not visa versa.
7. 1 Cleansing solutions
Sterile sodium chloride 0.9% solution is the most appropriate for irrigating wounds. Whena surgical wound has separated or has been surgically opened to drain pus, then the useof tap water may be considered for wound cleansing.
175 It is however preferable in
wounds which are not contaminated with faecal or other severe contamination matter thatstaff use sterile saline.
A variety of antiseptic preparations are sometimes used for more complex wounds.Traditional antiseptics (e.g. Eusol, diluted Milton, hydrogen peroxide, chlorhexidine withcetrimide) are quickly rendered ineffective by body fluids and pus. The potentialdisadvantages of using such antiseptics should be weighed against any possible benefitsbefore they are used.
176 NICE guidelines advise against the use of Eusol and mercuric
antiseptic on wounds.177
Products which contain polyhexamethylene biguanide (PHMB)have a broad range spectrum of biocidal activity with demonstrated clinical evidence tosupport their use.
178 Some studies have indicated that Fungi and Yeasts are more
important wound pathogens than previously reported and thus antimicrobial products mustbe able to target these pathogens if healing is to occur.
179
It is advisable to warm the cleaning solutions to body temperature just before use.
7.1.1 Sodium chloride 0.9% solutionThis isotonic solution does not cause chemical damage to cells and is thepreferred irrigating agent for wounds. Sodium chloride 0.9% does not require aprescription; all the other solutions do need a prescription.

181 However for
management of MRSA Stellisept as discussed below should be used.
7.1.5 StelliseptIf a wound is colonised or infected with MRSA it can washed using Stellisept atdressing changes.
182 The wound should subsequently be redressed using an
antimicrobial dressing according to its classification and in adherence with theEWMA Algorithm as illustrated in Figure 1.
