AimsAims
To provide context for skin problems in injectors
To identify main problems To differentiate between minor and
major wounds To discuss treatment options
![Page 3: ‘Understanding Skin And Wound Care’ Injecting Injuries and Wound Care Causes and Treatment Alison Coull Lecturer Department of Nursing and Midwifery, University.](https://reader030.fdocuments.net/reader030/viewer/2022032802/56649e005503460f94ae9243/html5/thumbnails/3.jpg)
ContextContext
86% of users attending medical clinics report cutaneous adverse effects
Access to wound care services may be poor
Perceived confidentiality related to service use
Some serious illness manifests itself initially in the skin
![Page 4: ‘Understanding Skin And Wound Care’ Injecting Injuries and Wound Care Causes and Treatment Alison Coull Lecturer Department of Nursing and Midwifery, University.](https://reader030.fdocuments.net/reader030/viewer/2022032802/56649e005503460f94ae9243/html5/thumbnails/4.jpg)
Injecting Drug UseInjecting Drug UseThe use of drugs to support
addiction which are injected through the skin.
People who are involved with drugs may have multiple social and
medical problems which may impact on skin
condition.

Implications of Injecting Implications of Injecting
Breach of protective barrier Skin damage and scarring Vein and vascular damage Clostridia infection Necrotizing Fasciitis Osteomyelitis

Common types of wounds Common types of wounds seen in drug users include:seen in drug users include:
Lumps and bumps Abscesses Injuries related to
self harm Traumatic wounds Groin sinus Chronic leg ulcers
![Page 8: ‘Understanding Skin And Wound Care’ Injecting Injuries and Wound Care Causes and Treatment Alison Coull Lecturer Department of Nursing and Midwifery, University.](https://reader030.fdocuments.net/reader030/viewer/2022032802/56649e005503460f94ae9243/html5/thumbnails/8.jpg)
Vascular BackgroundVascular Background
Arteries have thicker walls and work at higher pressure – they carry blood to the peripheries
Veins have thinner walls and carry blood back to the heart and lungs
Vein valves stop blood pooling as a result of gravity
Women have thinner veins
![Page 9: ‘Understanding Skin And Wound Care’ Injecting Injuries and Wound Care Causes and Treatment Alison Coull Lecturer Department of Nursing and Midwifery, University.](https://reader030.fdocuments.net/reader030/viewer/2022032802/56649e005503460f94ae9243/html5/thumbnails/9.jpg)
Injecting technique: venepuncture, Injecting technique: venepuncture, skin and muscle poppingskin and muscle popping
Injecting into the vein allows the drug to go straight into the bloodstream. The blood contains many white cells to deal with ‘foreign’ organisms.
Injecting into the subcutaneous tissues or into muscle allows the drugs to linger causing micro-organisms to thrive and tissue death
![Page 10: ‘Understanding Skin And Wound Care’ Injecting Injuries and Wound Care Causes and Treatment Alison Coull Lecturer Department of Nursing and Midwifery, University.](https://reader030.fdocuments.net/reader030/viewer/2022032802/56649e005503460f94ae9243/html5/thumbnails/10.jpg)
Problems with injectingProblems with injecting
Drug – heroin / cocaine / benzodiazepines
Micro-organisms Skin hygiene Acid Undissolved particles Poor technique Filter materials

LumpsLumps Poor injecting technique
Layered vein wall
False Aneurysms
Raised hardened lumps
Usually not red, hot or painful
![Page 12: ‘Understanding Skin And Wound Care’ Injecting Injuries and Wound Care Causes and Treatment Alison Coull Lecturer Department of Nursing and Midwifery, University.](https://reader030.fdocuments.net/reader030/viewer/2022032802/56649e005503460f94ae9243/html5/thumbnails/12.jpg)
AbscessesAbscesses
Painful, red, raised lumps
Hot to touch Filled with pus Usually caused by
micro-organisms

Chronic Leg UlcerationChronic Leg Ulceration
Wounds on the leg which are present for 4 weeks or more
May be independent of injection site
Require different assessment
![Page 14: ‘Understanding Skin And Wound Care’ Injecting Injuries and Wound Care Causes and Treatment Alison Coull Lecturer Department of Nursing and Midwifery, University.](https://reader030.fdocuments.net/reader030/viewer/2022032802/56649e005503460f94ae9243/html5/thumbnails/14.jpg)
Chronic wound: Groin SinusChronic wound: Groin Sinus
Femoral vein is larger, and thicker
More tolerant of repeated venepuncture
A sinus can develop allowing repeated use
Occasional arterial misadventure
![Page 15: ‘Understanding Skin And Wound Care’ Injecting Injuries and Wound Care Causes and Treatment Alison Coull Lecturer Department of Nursing and Midwifery, University.](https://reader030.fdocuments.net/reader030/viewer/2022032802/56649e005503460f94ae9243/html5/thumbnails/15.jpg)
Life threatening symptomsLife threatening symptoms Necrotizing Fasciitis
(clostridia) Often begins with a cellulitic
response from an established break in the skin but may start in deeper tissues
Erythema, bruising, grey discolouration, purple areas.
Vesicles containing foul smelling watery fluid known as ‘dishwater pus’
![Page 16: ‘Understanding Skin And Wound Care’ Injecting Injuries and Wound Care Causes and Treatment Alison Coull Lecturer Department of Nursing and Midwifery, University.](https://reader030.fdocuments.net/reader030/viewer/2022032802/56649e005503460f94ae9243/html5/thumbnails/16.jpg)

Deep Vein ThrombosisDeep Vein Thrombosis
Injecting may cause inflammation
Inflammation may promote clotting
This leads to swelling
Vein valve damage Clot may break off
and lodge in lungs

Post-Thrombotic SyndromePost-Thrombotic Syndrome
Prolonged swelling Heavy aching leg Multiple venous ectasia May lead to ulceration Can be prevented /
relieved by compression therapy

Principles of wound healingPrinciples of wound healing
Moist and warm environment speeds healing by improving cell division and migration
Always dress a wound that is wet Very small scabbed areas or dry
surgical stitch lines can be left exposed to the air
![Page 26: ‘Understanding Skin And Wound Care’ Injecting Injuries and Wound Care Causes and Treatment Alison Coull Lecturer Department of Nursing and Midwifery, University.](https://reader030.fdocuments.net/reader030/viewer/2022032802/56649e005503460f94ae9243/html5/thumbnails/26.jpg)
Managing wounds : Managing wounds : cleansingcleansing
Tap water Irrigate Don’t clean with
anything that leaves fibres behind
Do not rub Do not dry wounds

Slough Slough
A mixture of dead white cells, dead bacteria, re-hydrated necrotic tissue and fibrous tissue.
Can be soft or fibrous Often yellow, green
or grey

Black necrotic / red healingBlack necrotic / red healing Dead Tissue May be due to
ischaemia, infection, disease, or injury.
May appear blue-black, grey, or yellow.

InfectionInfection
May be managed with a topical antiseptic
Antibiotics – need to be taken at regular intervals and often don’t mix with alcohol

Filling SpaceFilling Space
Wounds heal from the base up
Cavities should be filled loosely with packing material - NOT ribbon gauze.
This allows the wound to drain, and for the base to fill with granulation tissue, but prevents a pocket forming with skin healing over.

Leg wounds tend to become chronic in drug users because of venous damage
If remaining unhealed at 4 weeks they require vascular assessment
Usually require compression bandaging

SummarySummary
Injecting Drug Users have both minor and major skin problems
Assessment is important – injection, history, cause, site
Infection can be serious Referral should be considered but may
not always be appropriate.
