To administer intravenous medications and fluids and remove
the cannula when it is no longer needed or if swelling occurs.
Procedure:
First: Insertion of Intravenous
Cannula
Equipment:
- Sterile gloves
- Two cannulas (sizes 24, 22)
- Three syringes (1 ml)
- Saline solution or sterile
water for injection
- Sterile gauze and cotton
- 70% ethyl alcohol
- Sterile towel
- Sterile scalpel
- Adhesive tape
- Tourniquet
- Sharps disposal container
Steps:
- Wash hands using routine
handwashing and prepare the required equipment.
- Examine the veins to determine
the best site for cannula insertion based on priority.
- Prepare pieces of adhesive tape
for securing the cannula.
- Disinfect the area with alcohol
using a unidirectional motion from top to bottom or a circular motion from
the center outward.
- Fill the syringe with saline or
sterile water.
- Open the cannula package.
- Inject saline into the cannula
to confirm its patency.
- Keep the cannula in its plastic
cover.
- Lightly tie the arm or leg
above the vein with a tourniquet to make the vein visible or instruct the
assisting nurse to apply pressure using their index finger.
- Insert the needle gently
without pushing it too far into the vein until blood appears.
- Release the tourniquet.
- Withdraw the stylet (needle)
while applying pressure on the skin above the vein to prevent blood flow.
- Place the stylet in its plastic
cover in case it is needed again if blood does not flow properly.
- Inject 1 ml of saline to ensure
the blood flow is unobstructed.
- Cover the cannula entry point
with the white cap.
- Place a piece of sterile gauze
under the cannula hub (especially if it has no wings) and another over the
insertion site.
- Remove gloves to secure the cannula
with adhesive tape.
- Record the date and time of
insertion, as well as the name of the person performing the procedure, on
the tape and in the documentation.
- Dispose of the used equipment
properly and place the stylet in the sharps container.
- Remove gloves and wash hands
using routine handwashing.
Precautions When Inserting a Cannula:
- Use a new sterile cannula for
each new attempt.
- Perform routine handwashing and
wear gloves before handling the cannula.
- Whenever possible, use upper
limbs for cannula insertion.
- If inserting the cannula in the
scalp, carefully remove excess hair using a scalpel and wash hands again.
- Attempt insertion in the lower
part of the arm first, moving upward if necessary.
- Avoid inserting the cannula in
areas with wounds, infections, or near joints.
- Avoid touching critical areas
of the cannula, including:
- Cannula opening
- Inner surface of the cap
- Upper port opening and its
inner surface
- Area in front of the wings
Second: Removal of
Intravenous Cannula
Indications for Removal:
- If the area around the needle
swells or shows signs of infection.
- Immediately after administering
blood, blood products, or lipids.
- After 72 hours of insertion
(ensuring a new cannula is placed in another site before removal and
verifying fluid flow in the new vein).
Equipment:
- Sterile gloves
- Sterile gauze
- 70% ethyl alcohol
- Surgical betadine
- Adhesive tape
- Sterile towel
- Medical waste bin with a red
bag
- Sharps disposal container
Steps:
- Perform routine handwashing and
prepare the equipment.
- Moisten the adhesive tape with
alcohol to ease removal and reduce pain.
- Disinfect the cannula site with
betadine and apply sterile gauze over the site to prevent bleeding.
- Dispose of the removed cannula
in the sharps container.
- Remove gloves and wash hands
using routine handwashing.
