However, the dressing should be replaced according to appropriate clinical procedures and manufacturer guidance.
Adhesive Cannula Fixators
Adhesive cannula fixators use a medical adhesive to attach the fixation dressing to the skin.
The adhesive helps hold the cannula in place and can reduce unnecessary movement.
When selecting an adhesive fixator, healthcare professionals should consider:
• Skin condition
• Required fixation strength
• Duration of use
• Patient comfort
• Location of the cannula
• Product specifications
For patients with fragile or sensitive skin, a suitable gentle adhesive product may be preferable.
Sterile Cannula Fixation Products
Sterile fixation products can be used when maintaining an appropriate level of asepsis around an IV insertion site is required.
These products are designed and packaged to support sterile application according to their intended use.
Healthcare professionals should check the packaging before use and should not use products if the packaging is damaged or the product is otherwise compromised.
Where Are Cannula Fixators Used?
Cannula fixators are commonly used in healthcare environments where peripheral IV cannulas are placed.
These may include:
• Hospitals
• Emergency departments
• Clinics
• Day-care treatment centres
• Nursing facilities
