Extravasation Extravasation Is…. • Infiltration, tissuing, displacement……………….. - at the end of the day they are all the same injury • The inadvertent administration of a cytotoxic drug, targeted therapy or iodinated contrast agent into the surrounding tissues, rather than into the vascular pathway as intended. • Vesicant extravasation is an oncological / parenteral therapy emergency. If we don’t take them seriously Late PresentationVinorelbine Extravasation.. Anthracycline Extravasation (? Incomplete washout ? ) 9 weeks after the event Day 1 Day 7 Day 30 Often Difficult to Diagnose • Extravasation? • Flare reaction? Flare reaction • Flare reaction – red streak, flushing along the vein • • • • • Caused by an inflammatory response Does not cause pain, although does cause ‘itching’ Usually the area is red and ‘blotchy’ (like nettle rash) Occurs in 3 – 6% of patients Often associated with Doxorubicin • Responds to topical steroids • Usually resolves in over 85% of patients within 45 minutes Recognising an extravasation 1. Visual assessment Initial Redness/erythema Swelling/oedema Later Inflammation Induration Exfoliation Blistering 2. Patient reporting Pain, discomfort Burning, stinging 3. The infusion – warning signs! The device alarms! Increased resistance when administering drugs – BACK FLOW Infusion becomes slow or sluggish Schulmeister 2011, Doherty 2010 The Nature of Extravasation Injuries Has Changed • The most important development in the prevention and management of extravasation is ‘the Chemotherapy Trained nurse’. • This has led to earlier detection of smaller volume extravasations, and a greater appreciation of the hazard and nature of the risk. • This has diminished the potential consequences of the injury and altered the intervention / observation dynamic. • The average volume of drug extravasated in 1985 was 11.6mls, in 1995 - 7.2mls and in 2005 - 3.1mls (www.extravasation.org.uk) Extravasation Rate • Statistics show that extravasations occur in 0.5% - 6.5% of cytotoxic administrations (Albanell and Baselga 2000) • Between 0.5% - 6% of cytotoxic drug administrations will result in an extravasation. (Dougherty and Oakley 2011) How quickly should a vesicant extravasation be washed out? •Ideally within 6 hours (Giunta 2004) Surgical Intervention – The ‘Saline Wash Out Technique’ Gault 1993 Documentation!!! • Need a complete history of the extravasation event with diagrams and photographs in the patient’s notes, including the planned follow-up for the patient. • Follow up – what was the outcome?! • PHOTOGRAPHIC EVIDENCE Alternative to SWOT? Antidotes…… Anthracyclines Topical DMSO, corticosteroids Mechlorethamine and Bendamustine Sodium Thiosulphate (injected locally) Vinca-Alkaloids Hyaluronidase (inj localy) Taxanes Hyaluronidase Schulmeister 2011, Doherty 2010, EONS 2007 Dexrasoxane (Savene) • Only antidote licensed for anthracycline extravasation • Given as a peripheral infusion within 6 hours of extravasation, then again at day 2 and 3. • The anthracycline (full dose) then has to be re given at day 4. • Cost– around £6,000 per treatment ‘package’. How can we help to minimize the risk of extravasation? • Do not site cannula in ACF or over bony prominences • Avoid multiple venepuncture! • Avoid small fragile veins! • Always cannulate distal to previous cannulation • Take time when cannulating (view the whole arm!) • Use a cannula placed specifically for purpose • Vesicant first (if possible) • Use a heat pad during administration • Refer for a CVC before problems arise!! Litigation? • £22.5k compensation - woman left scarred after chemotherapy drugs leaked from a port catheter site during treatment for breast cancer Remember • Extravasation is just one hazard of IV chemotherapy – not directly life threatening, but certainly has one of the most serious long term consequences.
