What are the common sites for cannula insertion?
The preferred sites for IV cannulation
- Hand. Dorsal arch veins.
- Wrist. Volar aspect.
- Cubital fossa. Median antecubital, cephalic and basilic veins.
- Foot. Dorsal arch.
- Leg. Saphenous vein at the knee.
What angle do you insert a cannula?
Insert the cannula at a 15-25 degree angle depending on the vein depth. Take care not to insert it too far into the lumen or it may penetrate the back wall. 2 Approaching the vein from the side: Position the cannula tip adjacent to the vein aimed towards it.
How can I improve my cannulation skills?
IV Therapy Tips and Tricks

- Explain the procedure –
- Hide needles –
- Use topical anesthesia –
- Divert patient’s attention –
- Follow past history of patients –
- Assess the vein carefully –
- Choose appropriate cannula size –
What is the best choice of cannula site?
The most common site for an IV catheter is the forearm, the back of the hand or the antecubital fossa. The catheters are for peripheral use and should be placed where veins are easy to access and have good blood flow, although the easiest accessible site is not always the most suitable.
How do you choose a vein for cannulation?
Choosing a vein
- You should select a site that is the least restrictive for the patient such as the posterior forearm or dorsum of the hand.
- Avoid areas near the elbow and wrist joints (to reduce the likelihood of dislodgement as a result of the patient’s movement).
What veins should I avoid for cannulation?
The veins of choice are the cephalic or basilic. Avoid using the antecubital veins as this will restrict the patient’s movement and increase the risk of complications such as phlebitis and infiltration (Dougherty & Watson, 2011; RCN, 2010).
Is Cannulating difficult?
Intravenous cannulation may be difficult and is associated with a high risk of complications. If the cannulation fails, this may further delay treatment and transport, potentially resulting in adverse patient outcomes. Cannulation may be difficult if the patient’s veins can not be seen or felt.
Why is Cannulating difficult?
Difficult cannulation may be due to many factors, such as patient’s age and comorbidities, health professional’s experience, cannula gauge and site of insertion.
What is the C shape of cannulation?
The unique C shape design helps stabilise the vein and stretch the skin for easier needle insertion. The shape of the Veinlite units also allow the user to apply gentle pressure and create a local tourniquet effect to further increase efficacy.
How many types of cannulas are there?
There are two main types of cannula: IV cannulas: IV cannulas consist of short, flexible tubing doctors place into a vein. Nasal cannulas: Nasal cannulas consist of flexible tubing that sits inside the nostrils and delivers oxygen.
What is venipuncture cutdown?
Venous cutdown is an emergency procedure in which the vein is exposed surgically and then a cannula is inserted into the vein under direct vision. It is used to get vascular access in trauma and hypovolemic shock patients when peripheral cannulation is difficult or impossible. The saphenous vein is most commonly used.
Who invented cannula?
One of the earliest such needles was the Strauss cannula which was designed in 1907 by Hermann Strauss.
