Wound care should support healing while reducing avoidable infection and tissue damage. Selection of cleansing methods and dressings depends on the wound, patient factors and local formulary. An aseptic technique protects vulnerable tissue; a universal dressing recipe is not appropriate for every wound.
Learning outcomes
- Describe preparation and aseptic principles
- Identify wound assessment elements
- Explain why dressing choice varies
- Document and escalate concerning changes
1. Assessment before action
Identify the patient and reason for treatment, check consent and prescribed wound plan, and assess pain and relevant allergies. Review wound origin, healing trajectory, surrounding skin, exudate and signs of complications. Evaluate whether specialist advice or escalation is indicated before commencing.
2. Equipment and clinical environment
Use the approved dressing pack, suitable gloves and PPE, prescribed dressing materials, waste disposal and authorised cleansing supplies. Prepare a clean working area and avoid placing sterile items on unprepared surfaces. Check packaging integrity and expiry dates.
3. Conceptual aseptic workflow
Perform hand hygiene at the indicated moments, protect key parts and key sites, remove existing materials safely and observe the wound. Use the approved cleansing and dressing procedure under supervision without allowing contaminated items to contact prepared materials. Dispose of waste correctly and repeat hand hygiene.
4. Pressure, perfusion, moisture and skin integrity
Wound healing is influenced by tissue perfusion, infection, nutrition, medication and mechanical stress. Assess the surrounding skin for maceration, damage and sensitivity. A dressing that works for one wound may be inappropriate for another because fluid control, tissue fragility and allergies differ.
5. Documentation and escalation
Record the wound site, relevant measurements according to protocol, appearance, patient-reported symptoms, dressing used, response and whom you informed. Be consistent with local classification tools and photography consent. Document changes clearly enough that another clinician can compare healing over time.
6. Common technique failures
Examples include using an expired product, breaking the aseptic field, touching a key part with contaminated gloves, using a dressing not in the care plan or failing to reassess pain. If an error occurs, pause and correct it according to policy.

Comparison table
| Concept | Meaning | Key distinction |
|---|---|---|
| Clean technique | Defined local care approach | Not equivalent to sterile technique |
| Aseptic non-touch | Protect key parts and sites | Requires trained practice |
| Wound exudate | Fluid from wound | Assess amount and character |
| Maceration | Moisture-related skin damage | Protect surrounding skin |
| Debridement | Removal of nonviable material | Requires competency and authorisation |
| Escalation | Specialist or urgent review | Based on signs and policy |
Diagram: stepwise learning workflow
Schematic educational flowchart. Follow the authorised clinical or regulatory process where applicable.
Applied case: A wound has increased pain and new spreading redness. A student wants to use a different antiseptic immediately.
The safer response is to reassess and communicate possible clinical deterioration, following the prescribed plan and local escalation, rather than improvising a product change.
Clinical safety alert: This educational guide does not authorise unsupervised clinical procedures, prescribing, changes in medicines or the withdrawal of infection precautions. Always follow current patient-specific orders, manufacturer instructions, institutional protocols and competency requirements.
OSCE demonstration and documentation
Before demonstrating this skill, confirm the simulated patient’s identity, explain the purpose, seek appropriate consent and assess environmental safety. Verbalise clinical reasoning at decision points instead of reciting a mechanical script. Maintain indicated hand hygiene and PPE, recognise where to stop or escalate, and document only observations and actions that actually occurred. A breach in technique should be corrected rather than concealed.
Evidence-based extended study guide (October 2026)
Why this section matters: The following explanations and worked scenarios expand the foundational lesson using official NMC, NICE, WHO or professional standards. They distinguish published requirements from locally governed clinical decisions.
First decide what type of wound is being assessed
A recent surgical incision healing by primary intention differs from a wound healing by secondary intention, a pressure injury, a vascular ulcer or an infected wound requiring specialised assessment. The indication for dressing change is therefore not simply “a wound is visible”. Consider surgical history, treatment orders, perfusion, pain, systemic symptoms and the wound plan. A learner should describe the wound using consistent terms rather than guessing its depth or stage without training.
Core assessment domains
Record anatomical location, approximate dimensions using the approved method, wound-bed appearance, exudate amount and character, wound edges, surrounding skin, odour if relevant, pain and changes since the previous assessment. The same dressing may behave differently in a heavily exuding wound and a nearly closed surgical incision. Photographs must follow consent, privacy and approved storage procedures. Pain and changes in local warmth or redness require contextual interpretation because inflammation is not always infection.
Aseptic non-touch principles
NICE NG125 recommends an aseptic non-touch technique for changing or removing surgical dressings. Protect key parts that must remain free from contamination and keep the working environment organised. Where a breach occurs, the correct response is to recognise it and restore an appropriate setup, not continue while hoping the contamination was harmless. Exact glove, equipment and preparation requirements depend on the procedure, wound type and local protocol.
Dressings, moisture and specialist input
Interactive dressings are intended to support an appropriate healing environment; selection considers exudate, skin tolerance, wound location and clinical goals. A more expensive product is not automatically superior. NICE advises specialist tissue-viability input for surgical wounds healing by secondary intention. Do not apply unprescribed antimicrobial agents or irrigate a wound based on a general article; those are procedure-specific and may be harmful.
Specific NICE surgical-wound recommendations
For certain postoperative surgical wound circumstances, NICE NG125 includes use of sterile saline for wound cleansing up to 48 hours after surgery and other recommendations for subsequent care, while emphasising aseptic non-touch dressing changes. These recommendations are not universal instructions for every chronic wound, burn or invasive procedure. In teaching, clearly state the wound population and source rather than extending surgical-site guidance to all skin injuries.
Documentation example
A useful record might state: “Left forearm surgical incision; dressing changed under approved aseptic protocol; edges approximated, small amount of clear exudate, surrounding skin intact; patient reports discomfort 2/10; new dressing product documented; no immediate concerns; reassessment date per plan.” This illustrates descriptive documentation only. Do not chart an observation that was not performed, and escalate any finding that meets the facility’s deterioration or infection criteria.
Reference table: verified details and exceptions
| Assessment domain | Record | Potential follow-up |
|---|---|---|
| Wound site | Precise anatomical location | Match previous records |
| Exudate | Amount and character | Assess change |
| Wound bed | Observed tissue appearance | Avoid unsupported staging |
| Periwound skin | Colour, warmth, integrity | Monitor change |
| Pain | Patient report and trend | Manage under prescribed plan |
| Dressing integrity | Secure, leaking or displaced | Follow change protocol |
Worked scenario: where students commonly go wrong
New pain and increasing exudate on a surgical incision. Document the change compared with previous assessment, review observations and promptly seek appropriate clinical review. The learner should not assume either that it is normal healing or that it proves bacterial infection from the dressing’s appearance.
Three questions answered
Does every wound dressing require the same technique?
No. Use the wound-specific local aseptic procedure and approved equipment.
When does NICE recommend ANTT for surgical dressings?
NICE NG125 includes aseptic non-touch technique for changing or removing surgical wound dressings.
Can a nurse use any topical antibiotic to prevent wound infection?
No. Use indicated products only according to clinical direction and evidence-based guidance.
