Overview Of Phlebitis and extravasation secondary to venous cannulation
Phlebitis and extravasation are complications that can occur secondary to venous cannulation, a common medical procedure used for intravenous (IV) therapy. **Phlebitis** refers to the inflammation of a vein, often caused by mechanical irritation, chemical irritation from infused medications, or infection. It presents with pain, redness, warmth, and swelling along the affected vein. **Extravasation** occurs when IV fluids or medications leak into the surrounding tissues instead of entering the vein, potentially causing tissue damage, necrosis, or severe pain. Both conditions are preventable with proper cannulation techniques and monitoring. Early recognition and management are crucial to minimize complications and ensure patient safety. ---
Symptoms of Phlebitis and extravasation secondary to venous cannulation
- Symptoms vary depending on the condition:
- Phlebitis: - Pain, tenderness, or burning along the vein. - Redness, warmth, or swelling at the IV site. - Palpable cord-like vein. - Fever or systemic signs if infection is present.
- Extravasation: - Swelling, pain, or burning at the IV site. - Skin discoloration, blistering, or necrosis in severe cases. - Reduced or absent blood return from the cannula. - Tissue damage or compartment syndrome in extreme cases. ---
Causes of Phlebitis and extravasation secondary to venous cannulation
- The causes of phlebitis and extravasation include:
- Phlebitis: - Mechanical irritation from the cannula. - Chemical irritation from hypertonic or acidic medications (e.g., potassium chloride, vancomycin). - Infection (e.g., bacterial colonization of the cannula). - Prolonged use of the same IV site.
- Extravasation: - Improper placement or dislodgement of the cannula. - High-pressure infusion or rapid injection of medications. - Use of vesicant drugs (e.g., chemotherapy agents, calcium chloride). - Fragile or small veins in elderly or pediatric patients. ---
Risk Factors of Phlebitis and extravasation secondary to venous cannulation
- Risk factors for these complications include:
- Phlebitis: - Prolonged IV therapy. - Use of irritant medications or solutions. - Poor cannulation technique or site selection. - History of previous phlebitis.
- Extravasation: - Use of vesicant or irritant medications. - Fragile veins (e.g., in elderly or pediatric patients). - High infusion rates or pressures. - Poor cannula fixation or patient movement. ---
Prevention of Phlebitis and extravasation secondary to venous cannulation
- Preventive measures include:
- Phlebitis: - Use proper cannulation techniques and aseptic procedures. - Rotate IV sites regularly. - Dilute irritant medications and infuse at recommended rates.
- Extravasation: - Use appropriate veins and secure the cannula properly. - Monitor IV sites frequently, especially with vesicant drugs. - Educate patients to report pain or swelling immediately. ---
Prognosis of Phlebitis and extravasation secondary to venous cannulation
- The prognosis is generally good with prompt intervention:
- Phlebitis: Most cases resolve within a few days after removing the cannula and providing supportive care.
- Extravasation: Mild cases resolve with conservative management, but severe cases may require surgical intervention or lead to permanent tissue damage. ---
Complications of Phlebitis and extravasation secondary to venous cannulation
- Potential complications include:
- Phlebitis: - Thrombophlebitis (vein thrombosis). - Cellulitis or systemic infection. - Chronic venous insufficiency.
- Extravasation: - Tissue necrosis or ulceration. - Compartment syndrome. - Permanent scarring or functional impairment. ---
Related Diseases of Phlebitis and extravasation secondary to venous cannulation
- These complications are associated with or can mimic other conditions, such as:
- Cellulitis: A bacterial skin infection that can occur at the IV site.
- Deep vein thrombosis (DVT): A blood clot in a deep vein, which can complicate phlebitis.
- Compartment syndrome: A severe complication of extravasation causing tissue ischemia.
- Allergic reactions: Localized reactions to IV medications or materials. Understanding these complications and their management ensures safer IV therapy practices.
Treatment of Phlebitis and extravasation secondary to venous cannulation
Management depends on the condition: 1. **Phlebitis**: - Remove the cannula and apply warm compresses. - Elevate the affected limb to reduce swelling. - Administer analgesics for pain relief. - Treat infection with antibiotics if present. 2. **Extravasation**: - Stop the infusion and remove the cannula immediately. - Elevate the affected limb. - Apply cold or warm compresses (depending on the medication). - Administer antidotes for specific vesicant drugs (e.g., hyaluronidase for certain chemotherapy agents). - Monitor for tissue damage and consult a surgeon if necrosis occurs. ---
