Chemotherapy Extravasation Flashcards
(37 cards)
What does extravasation refer to?
The leakage of chemotherapy drugs into surrounding tissues, causing local tissue damage, necrosis, or ulceration.
How are chemotherapy drugs classified based on their DNA-binding properties?
They are classified into DNA-Binding (Vesicants) and Non-DNA-Binding (Irritants or Vesicants).
What are DNA-Binding agents also known as?
Vesicants.
Name two examples of DNA-Binding chemotherapy agents.
- Anthracyclines (Doxorubicin, Epirubicin, Daunorubicin)
- Alkylating agents (Mustargen, Cisplatin, Carboplatin)
What type of tissue damage do DNA-Binding agents cause?
Severe tissue necrosis.
What are Non-DNA-Binding agents also known as?
Irritants or Vesicants.
Name two examples of Non-DNA-Binding chemotherapy agents.
- Vinca alkaloids (Vincristine, Vinblastine, Vinorelbine)
- Taxanes (Paclitaxel, Docetaxel)
What type of injury do Non-DNA-Binding agents cause?
Inflammation, pain, and possible necrosis.
What is the first treatment step for extravasation caused by DNA-Binding agents?
Cold compress (vasoconstriction to limit spread).
What is the role of topical DMSO in treating extravasation?
Reduces oxidative damage.
What is the ONLY FDA-approved antidote for anthracycline extravasation?
Dexrazoxane (Totect®).
When should Dexrazoxane be administered for it to be effective?
IV within 6 hours.
What is the first treatment step for extravasation caused by Non-DNA-Binding agents?
Heat compress (vasodilation helps disperse drug).
What is the role of Hyaluronidase in treating extravasation?
Breaks down hyaluronic acid, helping drug spread and absorb.
What does the mnemonic ‘Hot Vinca, Cold Dox’ help remember?
Management of extravasation for Vinca alkaloids and Doxorubicin/Anthracyclines
‘Hot’ refers to Vinca alkaloids which require heat and hyaluronidase, while ‘Cold’ refers to Doxorubicin which requires cold compress and DMSO plus dexrazoxane.
What do ‘Hot’ and ‘Cold’ represent in the mnemonic ‘Hot Vinca, Cold Dox’?
‘Hot’ represents Vinca alkaloids and ‘Cold’ represents Doxorubicin/Anthracyclines
‘Hot’ indicates the use of heat and hyaluronidase, while ‘Cold’ indicates the use of cold compress, DMSO, and dexrazoxane.
What is the focus of the mnemonic ‘DNA-Binders Love Cold’?
Management of extravasation for DNA-binding drugs
This includes Anthracyclines, Mitomycin, and Alkylators, which require cold compress and DMSO.
Which drugs are associated with the mnemonic ‘DNA-Binders Love Cold’?
- Anthracyclines
- Mitomycin
- Alkylators
These drugs are managed with cold compress and DMSO during extravasation.
What does the mnemonic ‘Vincas Need Heat & Help (Hyaluronidase)’ signify?
Management of extravasation for Vinca alkaloids
Vinca alkaloids require heat and hyaluronidase for effective management.
Which treatment is indicated for Vinca alkaloids according to the mnemonic ‘Vincas Need Heat & Help’?
Heat and Hyaluronidase
This treatment approach is necessary to manage extravasation effectively.
