Extravasation refers to the accidental leakage of intravenous medications, particularly vesicants, into the surrounding tissue, causing potential tissue damage and necrosis. Infiltration occurs when non-vesicant fluids or medications leak into the interstitial space, typically leading to swelling and discomfort without severe tissue injury. Explore detailed differences, symptoms, and management strategies for extravasation versus infiltration to enhance clinical care.
Main Difference
Extravasation occurs when vesicant drugs leak from a vein into surrounding tissues, causing potential severe tissue damage, while infiltration involves non-vesicant fluids or medications unintentionally entering the surrounding tissue, typically resulting in less serious damage. Extravasation requires immediate intervention due to the risk of tissue necrosis, whereas infiltration usually causes mild swelling, discomfort, and localized inflammation. Accurate identification and prompt management are critical to minimize complications in both conditions. Monitoring for signs such as pain, redness, and swelling at the infusion site helps differentiate between extravasation and infiltration.
Connection
Extravasation and infiltration both involve the unintended leakage of intravenous fluids into surrounding tissues, with extravasation specifically referring to the escape of vesicant drugs that can cause tissue damage. Infiltration typically involves non-vesicant solutions, resulting in swelling and discomfort without severe tissue injury. Understanding the distinction and connection between these events is crucial for prompt recognition and effective management to prevent complications in IV therapy.
Comparison Table
| Aspect | Extravasation | Infiltration |
|---|---|---|
| Definition | Unintentional leakage of vesicant (tissue-damaging) medications from a vein into surrounding tissue. | Leakage of non-vesicant fluids or medications from a vein into the surrounding tissue. |
| Cause | Displacement or rupture of the vein wall allowing vesicant drugs to escape. | Displacement or rupture of the vein wall leading to fluid leakage that is generally non-toxic. |
| Tissue Damage | Can cause severe tissue injury, necrosis, and blistering due to toxic effects of vesicants. | Usually results in swelling, tenderness, and discomfort, with minimal or no tissue injury. |
| Common Vesicant Agents | Chemotherapy drugs, dopamine, calcium chloride, potassium chloride. | Saline, dextrose, some antibiotics, and other non-vesicant IV fluids. |
| Signs and Symptoms | Pain, burning sensation, redness, swelling, blister formation, and tissue necrosis. | Swelling, coolness, pallor, discomfort, and absence of necrosis or blistering. |
| Nursing Interventions | Stop infusion immediately, aspirate drug if possible, elevate limb, notify healthcare provider, apply antidotes if available, and monitor tissue closely. | Stop infusion, elevate limb, apply warm or cold compress depending on fluid, and monitor site for improvement. |
| Prevention strategies | Use central venous access for vesicant drugs, frequent site assessments, secure IV catheters properly, and patient education. | Ensure proper catheter placement, regular monitoring, and use of appropriate vein size for cannulation. |
| Clinical Implications | Requires urgent intervention to prevent serious complications including tissue necrosis and potential surgery. | Typically resolves with conservative management but requires monitoring to prevent progression. |
Vesicant
Vesicants in nursing refer to potent chemical agents that cause severe tissue damage and blistering upon extravasation during intravenous administration. Common vesicants include chemotherapy drugs such as doxorubicin, vincristine, and nitrogen mustard, which require careful handling to prevent skin injury. Prompt intervention with protocols involving cold or warm compresses and antidotes like dexrazoxane is critical to minimizing necrosis and preserving limb function. Nursing professionals must perform vigilant site assessments and maintain stringent infusion practices to mitigate risks associated with vesicant therapy.
Non-vesicant
Non-vesicant medications in nursing refer to intravenous drugs that do not cause tissue damage or blistering if they infiltrate surrounding tissues. These solutions, such as normal saline and certain antibiotics, are safely administered through peripheral or central lines without the risk of vesicant-induced complications. Proper identification and handling minimize patient discomfort and prevent extravasation injuries. Nurses must monitor infusion sites closely to ensure patient safety during administration.
Tissue damage
Tissue damage in nursing refers to the injury or destruction of body tissues caused by factors such as pressure ulcers, burns, surgical wounds, and trauma. Effective management involves assessing the extent of damage, implementing wound care protocols, and preventing infection through proper hygiene and dressing changes. Nurses play a critical role in monitoring tissue perfusion and promoting healing by ensuring adequate nutrition and mobility for patients. Early intervention reduces complications and improves patient outcomes in cases of tissue injury.
IV therapy
IV therapy is a crucial nursing procedure involving the administration of fluids, medications, and nutrients directly into a patient's bloodstream through a vein. Proper technique and aseptic protocols reduce the risk of complications such as phlebitis, infiltration, and infection. Nurses must assess vein condition, select appropriate catheter size, and monitor infusion rates to ensure patient safety and therapeutic efficacy. Mastery of IV therapy enhances patient outcomes in clinical settings including hospitals, outpatient clinics, and emergency care.
Early detection
Early detection in nursing significantly improves patient outcomes by enabling prompt intervention and reducing the progression of diseases. Nurses utilize evidence-based screening tools such as the Braden Scale for pressure ulcer risk and the Glasgow Coma Scale for neurological assessment to identify early signs of deterioration. Continuous patient monitoring and routine assessments, including vital signs and symptom evaluation, play a crucial role in recognizing subtle changes in health status. Implementing standardized protocols for early detection decreases hospital readmission rates and enhances overall care quality.

IV Therapy: The Difference between Infiltration and Extravasation - Infiltration refers to IV fluid leaking into surrounding tissue, while extravasation is infiltration involving vesicant drugs that can cause tissue damage, blistering, and necrosis.
Infiltration vs Extravasation in IV Therapy - Simple Nursing - Infiltration is the accidental leakage of non-irritant IV fluids into tissue, whereas extravasation is leakage of vesicant or irritant medication causing potential tissue injury.
What are current recommendations for treatment of drug extravasation? - Extravasation involves leakage of vesicant drugs causing tissue necrosis and severe damage, while infiltration involves non-vesicant fluid leakage with less risk of harm.
FAQs
What is extravasation in medical terms?
Extravasation in medical terms is the unintentional leakage of intravenous fluids or medications from a vein into the surrounding tissue.
What is infiltration in infusion therapy?
Infiltration in infusion therapy is the accidental leakage of intravenous fluid or medication into the surrounding tissue instead of the vein.
How does extravasation differ from infiltration?
Extravasation involves the leakage of vesicant or irritant drugs from a vessel into surrounding tissue causing tissue damage, while infiltration refers to the unintentional leakage of non-vesicant fluids or medications into the surrounding tissue without causing severe harm.
What causes extravasation during IV therapy?
Extravasation during IV therapy is caused by the accidental leakage of vesicant or irritant drugs from the vein into surrounding tissues due to vein perforation, catheter displacement, or improper insertion.
What are common signs of infiltration?
Common signs of infiltration include unexpected network traffic spikes, unauthorized access attempts, unusual login times, presence of unfamiliar files or processes, and alerts from security software.
How is extravasation treated in patients?
Extravasation is treated by immediately stopping the infusion, elevating the affected limb, applying cold or warm compresses depending on the causative agent, administering specific antidotes such as hyaluronidase or phentolamine, and monitoring tissue for necrosis or infection.
What are the complications of infiltration and extravasation?
Complications of infiltration and extravasation include tissue necrosis, infection, compartment syndrome, nerve damage, pain, swelling, erythema, and impaired limb function.
