Insect bites and stings Flashcards
(10 cards)
What are common complications of insect bites and stings?
Local skin trauma, allergic reactions, systemic toxicity, transmission of infections (e.g., Lyme disease), and secondary infections.
What severe systemic reaction can occur from a sting?
Anaphylaxis.
When should immediate hospital admission be arranged after a sting?
For suspected systemic reaction (e.g., anaphylaxis), face/mucosal stings risking airway/vision, severe immunosuppression with infection, or worsening cellulitis.
What should be done immediately if a stinger is visible?
Remove it quickly by scraping sideways with a card or fingernail.
How should a tick be properly removed?
Grasp close to the skin and pull upward gently and firmly—don’t twist.
What medications may be used for transient local reactions?
Paracetamol, ibuprofen, topical corticosteroids, and oral antihistamines.
How should secondary skin infections (e.g., cellulitis) be treated?
With oral antibiotics following local guidelines.
What should be done if insect bites are due to infestation?
Eradicate the source, e.g., pest control for bedbugs or treating pets for fleas.
How can tick bites be prevented?
Wear long light-colored clothing, use DEET repellent, and check skin/pets regularly.
What is deet repellent?
Insect repellent that contains the active ingredient DEET (N,N-diethyl-meta-toluamide) - doesn’t kill insects — instead, it interferes with their ability to detect humans by masking scent cues like carbon dioxide and body odor.
