How does phentolamine treat extravasation?
Phentolamine blocks alpha-adrenergic receptors to directly antagonize the effects of norepinephrine.
How do you treat amiodarone extravasation?
For a vasopressor extravasation, warm compresses and administration of a vasodilator are recommended. For osmolarity, pH, absorption refractory, and cytotoxic concentration-dependent vesicants, warm compresses and administration of hyaluronidase are recommended.
How do you treat extravasation of vasopressors?
Phentolamine mesylate, dosed at 5–10 mg in 10 mL of saline injected into the area of extravasation within 12 hours, is the only pharmacological treatment for vasopressor extravasation approved by the Food and Drug Administration.
What to do if amiodarone infiltrates?
Notify the healthcare provider. Elevate the affected limb to minimize swelling and encourage resorption of the drug via the lymphatic system. Apply dry warm or cold compresses as indicated depending on the drug extravasated.
What is an immediate symptom of extravasation?
It is essential to recognize that an extravasation has taken place as quickly as possible. Signs and symptoms of vesicant extravasation include swelling, redness and/or discomfort that is often described as a burning or stinging sensation.
What happens when extravasation takes place?
Extravasation occurs when a vesicant drug leaks out of the vein and into the surrounding tissue. When this happens, a person will likely experience serious tissue damage, including ulceration and tissue death, if they do not receive treatment in time.
How do you recognize extravasation?
Signs and symptoms of extravasation may include the patient’s report of pain or burning sensation at the site, possible blanching, redness and edema at the insertion site and surrounding tissue. There may also be cooler temperature at the site and absent backflow of blood.
What is difference between infiltration and extravasation?
The difference between an infiltration and extravasation is the type of medicine or fluid that is leaked. Infiltration – if the fluid is a non-vesicant (does not irritate tissue), it is called an infiltration. Extravasation – if the fluid is a vesicant (a fluid that irritates tissue), it is called an extravasation.
How to treat ischemia Q8 hrs PRN with terbutaline?
Elevation of the site of extravasation. Topical nitroglycerin 2%, apply a 1-inch strip to the site of ischemia q8 hrs prn; monitor for hypotension. Dilute 1 mg terbutaline in 10 ml NS. Inject locally across symptomatic sites.
How many milligrams of terbutaline for Code Blue?

Is there an alternative treatment for vasopressor extravasation?
Alternative Pharmacological Management of Vasopressor Extravasation in the Absence of Phentolamine Vasopressor extravasation is a rare adverse drug reaction that can lead to tissue damage, ischemia, and necrosis of the affected area when vasopressors are administered peripherally.
Which is the best treatment for dobutamine extravasations?
Treatment of dobutamine extravasations remains speculative because reports of successful treatment are few. Terbutaline, as mentioned previously, has been successful for the reversal of a mixed dopamine and dobutamine extravasation. 31 Phentolamine and nitroglycerin remain reasonable treatment options for dobutamine extravasations.
