IV Cannula Bleeding: Causes, Management, and Prevention


IV cannula bleeding, also known as extravasation or infiltration, occurs when medication or fluids leak into the surrounding tissue instead of entering the intended bloodstream. This blog post will discuss the causes, management, and prevention of IV cannula bleeding, providing valuable insights for healthcare professionals.

Causes of IV Cannula Bleeding:

1. Needle dislodgment: One common cause is when the IV cannula needle becomes dislodged from the vein, causing leakage into the surrounding tissue.

2. High pressure: Excessive pressure from the IV pump or gravity can lead to increased tissue resistance, resulting in cannula bleeding.

3. Vessel fragility: Fragile or compromised blood vessels can easily rupture during cannulation, leading to bleeding.

4. Improper cannula size: Using a cannula that is either too small or too large for the patient’s vein can increase the risk of bleeding.

Management of IV Cannula Bleeding:

1. Recognizing the problem: Healthcare professionals should conduct frequent assessments to identify signs of cannula bleeding, such as swelling, pain, or coolness at the insertion site.

2. Prompt action: As soon as bleeding is detected, it’s crucial to stop the infusion and remove the cannula carefully.

3. Elevation and pressure: Applying pressure to the site while elevating the patient’s limb can help control bleeding and reduce hematoma formation.

4. Cold compress: Placing a cold compress on the affected area can help minimize swelling and relieve pain.

Preventing IV Cannula Bleeding:

1. Proper cannula selection: Choosing the appropriate size and type of cannula based on the patient’s condition and the intended treatment can reduce the risk of bleeding.

2. Skillful insertion technique: Healthcare professionals should be well-trained in cannulation techniques to minimize the chances of vessel injury.

3. Securing the cannula: Using reliable dressing techniques and securement devices can prevent accidental dislodgment and subsequent bleeding.

4. Regular monitoring: Continuous monitoring of the insertion site, along with assessing the infusion flow, can help detect any signs of bleeding early on.


IV cannula bleeding is a potential complication that healthcare professionals should be well-prepared to handle. By understanding the causes, implementing appropriate management strategies, and following preventive measures, the risk of IV cannula bleeding can be significantly reduced. Proper training, vigilance, and adherence to best practices are crucial in ensuring patient safety during intravenous therapy.
