How is extravasation of blood treated?
At the first sign of extravasation, the following steps are recommended: (1) stop administration of IV fluids immediately, (2) disconnect the IV tube from the cannula, (3) aspirate any residual drug from the cannula, (4) administer a drug-specific antidote, and (5) notify the physician (Fig.
What is hyaluronidase an antidote for?
Experimental studies suggest that hyaluronidase, an enzyme that degrades hyaluronic acid and improves the absorption of locally injected drugs, can reduce the risk of progressing to skin necrosis.
What are current recommendations for treatment of drug extravasation?
Warm compresses are preferred for extravasation of specific drugs including vinca alkaloids, etoposide, vasopressors, and oxaliplatin to increase local blood flow and enhance drug removal. Apply compresses for 20 to 60 minutes 3 or 4 times daily for the first 24 to 72 hours after extravasation occurs.
How does hyaluronidase work on extravasation?
Hyaluronidase degrades glycosaminoglycans and hyaluronic acid, with subsequent increases in tissue permeability and dispersion of extravasated agent. Hyaluronidase has been used for extravasation by etoposide, taxanes (ie, paclitaxel, docetaxel, and cabazitaxel), and vinca alkaloids.
When do you give hyaluronidase extravasation?
The administration should be done immediately, with benefit seen when given within 3 hours of insult. In pediatric patients or infants, a 27–30 gauge needle is used to inject five 0.2 mL injections of hyaluronidase around the infiltration site in a circular pattern.
How do you administer hyaluronidase for extravasation?
Hyaluronidase (150 unit in 1 mL) should be administered through five 0.2 mL subcutaneous injections into the extravasation site. For pediatric patients, it has been shown that the administration of 15 units of hyaluronidase is effective to resolve the extravasation.
How does hyaluronidase work in extravasation?
Optimal management of intravenous extravasations remains controversial. The enzyme hyaluronidase degrades hyaluronic acid, a constituent of the normal interstitial barrier; by degrading interstitial bonds, it can increase the distribution and absorption of locally injected substances.
How is hyaluronidase administered?
With the patient prone, 75 Units of Hydase™ (hyaluronidase injection) is injected subcutaneously over each scapula, followed by injection of the contrast medium at the same sites.
When is phentolamine used for extravasation?
You’ll want to give the phentolamine as soon as possible, although it may be effective as long as 12 hours after the extravasation.
How do you administer hyaluronidase?
How to use hyaluronidase
- Draw up 10ml of water for injection or 0.9%normalsalinein a syringe.
- Reconstitute the hyaluronidase 1500IU with 1ml of the 10ml of normal saline or water for injection.
- Rotate the vial to ensure the powder is fully dissolved.
When do you take hyaluronidase?
INDICATIONS FOR THE USE OF HYALURONIDASE IN AESTHETIC PRACTICE
- Vascular occlusion.
- Blindness.
- Tyndall effect.
- Unacceptable cosmetic outcome.
- Delayed onset nodules.
- Allergic or immunogenic reaction to the HA dermal filler.
What is the role of hyaluronidase in the management of extravasations?
Optimal management of intravenous extravasations remains controversial. The enzyme hyaluronidase degrades hyaluronic acid, a constituent of the normal interstitial barrier; by degrading interstitial bonds, it can increase the distribution and absorption of locally injected substances.
What are the treatment options for intravenous (IV) extravasation?
At the first sign of extravasation, the following steps are recommended: (1) stop administration of IV fluids immediately, (2) disconnect the IV tube from the cannula, (3) aspirate any residual drug from the cannula, (4) administer a drug-specific antidote, and (5) notify the physician (Fig. 1). Open in a separate window Fig. 1.
What is the first step in the treatment of extravasation?
Nursing interventions At the first sign of extravasation, the following steps are recommended: (1) stop administration of IV fluids immediately, (2) disconnect the IV tube from the cannula, (3) aspirate any residual drug from the cannula, (4) administer a drug-specific antidote, and (5) notify the physician (Fig. 1).

What happens when hyaluronidase is injected into the body?
HYALURONIDASE IN THE BODY When hyaluronidase is injected into the body, its activity gradually decreases over time as a result of dilution, diffusion, and deactivation [7]. Deactivation is caused by anti-hyaluronidase activity, which proceeds at different rates in subcutaneous tissue and the plasma.
