What are the risks of extravasation?
Certain patients have been found to be at increased risk for extravasations, including those who cannot communicate adequately (e.g., the elderly, infants and children, and patients with altered consciousness), severely ill or debilitated patients, and patients with abnormal circulation in the limb to be injected. Patients with altered circulation include those with atherosclerotic peripheral vascular disease, diabetic vascular disease, Raynaud’s disease, venous thrombosis or insufficiency, or prior radiation therapy or extensive surgery (e.g., axillary lymph node dissection or saphenous vein graft harvesting) in the limb to be injected. Certain intravenous access sites (e.g., hand, wrist, foot, and ankle) are more likely to result in extravasation and should be avoided if possible. In addition, injection through indwelling peripheral intravenous lines that have been in place for more than 24 hours and multiple punctures into the same vein are associated with an increased risk of extravasation.
How long to follow up on contrast medium injury?
Because the severity and prognosis of a contrast medium extravasation injury are difficult to determine on initial evaluation of the affected site, close clinical follow-up for several hours is essential for all patients in whom extravasations occur.
What are the symptoms of compartment syndrome?
An immediate surgical consultation is indicated for any patient in whom one or more of the following signs or symptoms develops: progressive swelling or pain, altered tissue perfusion as evidenced by decreased capillary refill at any time after the extravasation has occurred, change in sensation in the affected limb, and skin ulceration or blistering. It is important to note that initial symptoms of a compartment syndrome may be relatively mild (such as limited to the development of focal paresthesia).
Where should extravasation events be documented?
All extravasation events and their treatment should be documented in the medical record, especially in the dictated imaging report of the obtained study, and the referring physician should be notified.
Does extravasation cause pain?
Although most patients complain of initial swelling or tightness, and/or stinging or burning pain at the site of extravasation, some experience little or no discomfort. On physical examination, the extravasation site may be edematous, erythematous, and tender.
What is extravasation in a vein?
Extravasation is defined as the leakage or inadvertent administration of a vesicant drug or solution from a vein into the extravascular space. 1 Infiltration, often used in reference to extravasation, refers to leakage of a non-vesicant drug or solution. 2,3 Initial symptoms of extravasation are similar to infiltration and include persistent pain, burning, stinging, swelling, and either blanching or erythema at the site of injection or along the course of the vein. However, vesicants are differentiated from non-vesicants in that they can cause tissue necrosis, blistering, and ulceration. Damage from extravasation can progress to a significant degree, causing permanent disability and disfigurement, and necessitating surgical debridement or skin grafting. 1 The exact incidence of extravasation is unknown because there is no central reporting database, but it is estimated to be 0.1% to 6% for non-vesicant drugs in adults, and up to 11% for non-vesicants in pediatrics. For vesicant drugs and chemotherapeutic agents, the incidence has been reported to range from 0.01% to 6%. 2
What is the best approach to extravasation injury?
3-6 Preventive measures include appropriate dilution of medication, infusion of medication via the appropriate rate of administration , ensuring patency of the vascular access device, careful monitoring of infusions during administration, use of clear tape or dressings to allow for visual inspection of the infusion site, and immobilization of the extremity with the IV cannula.
What is non-cytotoxic management?
Management of extravasation of non-cytotoxic drugs. The management of non-cytotoxic drugs is largely supportive and non-pharmacological, except where antidotes exist, such as for vasopressors. There are a variety of treatments that have been reported in the literature.
What are the risk factors for extravasation?
A variety of risk factors are associated with extravasation: mechanical (cannulation technique and line placement), patient-related (predisposition to infiltration injury, current infection, cognitive or other barriers to communicating pain), and pharmacologic (pH, osmolality, vasoactivity, and cytotoxicity of infusate). 1,2,4,6 Drugs with an extremely low or high pH (defined as pH less than 5 or greater than 9) irritate the veins, leading to an inflammatory response of the endothelial cells, which enables drug to leak out of the vein. Osmolality is also a consideration, as differences in osmotic pressure can damage endothelial cells, leading to potential for drug leakage from vessels. Certain drugs cause vasospasms, which result in back pressure at the intravenous (IV) site and may expand the puncture site in the vein, allowing leakage to occur; drugs that act as vasoconstrictors can also cause tissue ischemia. Some drugs, including anti-cancer agents, are directly cytotoxic to cells. Cytotoxic agents can be further subdivided into DNA-binding and non–DNA-binding agents. Additionally, administration factors, including the experience of personnel administering the injection, the injection technique, and the number of venipuncture attempts to establish a line, contribute to the risk of extravasation, as does the fragility of the patient’s veins.
Can drugs cause tissue ischemia?

Where is the most leakage from venous access?
higher percentage of leakage from venous access in the back of the hand, wrist, foot and ankle. likely related to a smaller amount of subcutaneous tissue and the fact that veins are more fragile in these regions.
When to use extravasation?
Strictly-speaking, 'extravasation' should be used for leakage of contrast from blood vessels only. However it is widely used in a more general sense when contrast escapes from any normal anatomical structure into the surrounding soft tissues, e.g. leak of contrast medium from the renal tract after iatrogenic ureteric injury.
Is extravasation less likely with manual injections?
with manual injection, extravasation is thought less likely, as there is direct supervision of contrast administration. likely related to a smaller amount of subcutaneous tissue and the fact that veins are more fragile in these regions.
Does contrast media reduce soft tissue injury?
Non-ionic low-osmolar contrast media are known to reduce the risk of severe soft tissue injury, but the potential for soft tissue injury is often related to the volume of contrast media that extravasates 1.
