Situation in Forth Valley and
Elsewhere
 Considerable
morbidity and mortality
associated with Cannula site infection
 Patient dies from
infection of an
intravascular
device, how do
you defend yourself?
IV Cannula, Whose Responsibility Is It?
EVERYBODY’S
Prevention of Cannula
Site Infection
Prevention of Cannula Site
Infection
 Does
the patient need IV access for
TREATMENT?
 If the answer is YES, proceed to the
PVC insertion bundle
 Remember “bleeding the patient”
does not qualify as “need” for
insertion of an IV cannula
PVC Insertion Bundle
A
PVC is clinically indicated
 Hand hygiene is carried out
 Skin is decontaminated
 Aseptic (no touch) technique
 Sterile dressing including date and

Follow Up
 Regular
monitoring of the site by the
staff on the ward
 Documentation in patient’s notes
 When to replace the cannula, 72 hrs
 When to remove the cannula, clinical
need
 When is a cannula site infected
What to Watch for?
 Sometimes
the first clue is pain at
the site of insertion
Infected Cannula Site
 Documentation
alone will not cure it
 Swab the site for culture and
sensitivity
 Assess the clinical picture
 Commence appropriate antibiotic
treatment
–
–
choice of antibiotic
choice of mode of administration
Do NOT Think of Treating Local Infection
with Local Antibiotic Ointment
Developments in Forth Valley
 Front
door services, need for IV
access
 Documentation, stickers in notes
 PVC care bundle implementation
 Change of skin cleansing solution
 ? Change of IV cannula brand
? The Future in Forth Valley
