OSCE Style Questions Flashcards
(12 cards)
What is the pharmacodynamics of botulinum toxin?
Botulinum toxin works by inhibiting acetylcholine release at the neuromuscular junction, leading to muscle paralysis and reduced wrinkle formation.
What risks and complications should you disclose for botulinum toxin?
Risks include bruising, swelling, asymmetry, and potential for eyelid ptosis.
What documentation is essential before administering botulinum toxin?
Informed consent and a detailed treatment plan should be documented.
What is the pharmacodynamic cause of blanching and severe pain after dermal filler injection?
Blanching and pain are likely due to vascular occlusion caused by filler compressing blood vessels.
What immediate steps should you take for vascular occlusion management?
Immediate steps include stopping the injection, assessing the area, and applying warm compresses.
How does hyaluronidase act in vascular occlusion situations?
Hyaluronidase breaks down hyaluronic acid in the filler, helping to restore blood flow.
What is the likely diagnosis for dizziness and metallic taste after lidocaine application?
The likely diagnosis is lidocaine toxicity.
What is the pharmacodynamic mechanism behind dizziness and metallic taste from lidocaine?
These symptoms are due to lidocaine’s effects on the central nervous system and its ability to cross the blood-brain barrier.
What is the appropriate clinical response to lidocaine toxicity?
The appropriate response includes monitoring the patient and providing supportive care.
What are the legal requirements for prescribing and delegation in aesthetics?
Prescribing must be done by a qualified practitioner, and delegation of tasks must comply with local regulations.
What are the pharmacodynamic considerations of filler placement?
Considerations include the interaction of the filler with surrounding tissues and the potential for vascular compromise.
What should be documented for governance and accountability in aesthetic procedures?
Documentation should include consent, treatment details, and any adverse events.
