Phlebitis Due to IV Cannula

Phlebitis is a common complication that can occur due to the use of an intravenous (IV) cannula. It is the inflammation of the vein where the cannula is inserted, and if not promptly identified and treated, it can lead to serious complications. In this blog post, we will explore the causes, symptoms, and preventive measures to reduce the incidence of phlebitis caused by IV cannulas.

Causes of Phlebitis

There are several factors that can contribute to the development of phlebitis:

  • Prolonged cannulation – when the IV cannula remains in place for an extended period, it can irritate the vein walls and trigger inflammation.
  • Improper technique – if the cannulation procedure is carried out without following proper aseptic technique, it can introduce bacteria into the vein, leading to infection and subsequent phlebitis.
  • Inadequate catheter stabilization – if the cannula is not securely taped or anchored, it can move within the vein, causing irritation and inflammation.
  • Chemical irritation – certain medications or solutions administered through the cannula can irritate the vein, resulting in phlebitis.

Symptoms of Phlebitis

Phlebitis can manifest with the following signs and symptoms:

  • Redness and warmth over the cannulation site
  • Tenderness or pain along the vein
  • Swelling or a lump at the insertion site
  • Palpable cord-like structure over the vein
  • Systemic signs of infection such as fever, chills, or malaise (in more severe cases)

Preventive Measures

To minimize the risk of phlebitis related to the use of IV cannulas, healthcare professionals should:

  1. Use aseptic technique during cannula insertion and regularly assess the cannulation site for signs of inflammation.
  2. Ensure proper catheter stabilization to prevent movement and friction within the vein.
  3. Replace cannulas periodically, following hospital protocols, to prevent complications related to prolonged use.
  4. Administer medications and solutions at recommended rates and concentrations to minimize chemical irritation to the vein.
  5. Monitor patients for any signs of phlebitis and provide appropriate care and treatment in a timely manner.
  6. Education patients on maintaining good hygiene and reporting any symptoms promptly.


In conclusion, phlebitis due to IV cannulas is a potential complication that can cause significant discomfort and complications for patients. By following proper insertion techniques, regular assessment, and adherence to hospital protocols, healthcare professionals can reduce the incidence of phlebitis. In addition, educating patients about the importance of early reporting and good hygiene practices can further contribute to better outcomes. It is crucial to prioritize patient safety and take all necessary precautions to prevent phlebitis and ensure optimal care.
