Peripheral IV Cannula Care at Home
Before any use, identify the prescribed therapy and inspect the full site and limb. Stop and obtain clinical direction for pain, burning, swelling, coolness, blanching, leakage, spreading redness, a damaged connector, resistance or an uncertain position. Do not push against resistance, conceal a wet dressing or restart through a questionable cannula. Sudden breathlessness, collapse or severe allergic features require emergency help through 999.
Who this guide is for
- People discharged with a temporary peripheral IV cannula
- Families protecting a cannula between prescribed visits
- Care coordinators preparing for intermittent IV therapy
Judge the device in the context of the treatment
Record the insertion location and date, cannula size if known, reason for access, medicine or fluid prescribed, dose timing, flush order, allergies and the service responsible for replacement. Compare the present limb with the opposite side and with the last documented assessment rather than relying on one isolated observation.
During and after authorised use, watch the person as well as the site. Document comfort, patency checks required by the protocol, dressing condition and any response to treatment. If the route becomes unusable, protect the person from missed therapy by contacting the named service instead of improvising another use.
- Current indication and prescription
- Site and limb comparison
- Protocol-specific patency check
- Failed-access contingency
Check whether the cannula still earns its place
Confirm why the cannula remains, what is next due through it, insertion date, last use and who owns the removal decision. A device without a current purpose adds skin, infection and dislodgement risk; seek a removal decision rather than keeping it automatically.
New tenderness, warmth, redness, a palpable vein, swelling, coolness, leakage, bleeding, resistance or a displaced hub changes the plan. A transparent dressing helps inspection, but an intact appearance does not rule out pain or a deeper problem.
Protect the limb between treatments
Keep the dressing clean, dry and secure, and the cannula free from pressure or pulling during sleep, transfers and clothing changes. Do not submerge the site, put cream beneath the dressing, manipulate the hub or use it outside the written plan.
Stop use and seek prompt review for pain, redness, warmth, swelling, leakage, blocked flow, fever or rigors, or partial dislodgement. Never push it back or flush against resistance. Severe swelling, blistering, colour change, intense pain, breathlessness or collapse needs urgent escalation.

Questions families often ask
Can the cannula stay in until the next planned dose?
Only if it remains required and passes the prescribed assessment. Symptoms or loss of integrity require review sooner.
