What is the maximum recommended area for applying compounded topical anesthetic (e.g., BLT cream) to minimize systemic toxicity risk?
Answer: Areas over 600 cm² should be avoided or split into multiple sessions
Large application areas increase systemic absorption of topical anesthetics; limiting surface coverage reduces the risk of CNS and cardiac toxicity from lidocaine overdose.
A patient develops perioral tingling and dizziness after topical anesthetic application. The technician should:
Answer: Remove the anesthetic, monitor vitals, and summon medical assistance immediately
Perioral tingling and dizziness are early signs of local anesthetic systemic toxicity (LAST); the anesthetic must be removed immediately and medical help obtained.
Why is post-treatment cooling recommended after non-ablative fractional laser procedures?
Answer: To reduce residual heat accumulation and minimize post-inflammatory erythema and edema
Post-treatment cooling removes residual heat from the skin, reducing the duration of thermal injury response and limiting erythema, edema, and patient discomfort.
In laser tattoo removal, inadequate cooling between pulses can result in:
Answer: Increased risk of epidermal blistering and scarring
Without adequate inter-pulse cooling in tattoo removal, heat accumulates in the epidermis, raising the risk of epidermal blistering, crusting, and permanent scarring.
Which of the following is a contraindication to the use of prilocaine-containing topical anesthetics?
Answer: Infants under 12 months and patients with G6PD deficiency
Prilocaine increases methemoglobin levels; infants lack sufficient methemoglobin reductase and G6PD-deficient patients cannot reduce methemoglobin, making both groups high-risk for toxicity.
Cold air cooling set to -30°C is being used during Q-switched laser tattoo removal. The primary purpose is to:
Answer: Protect the epidermis from non-specific thermal damage during high-peak-power pulses
Cold air cooling during Q-switched tattoo removal reduces non-specific epidermal heating from the ultra-short, high-peak-power pulses, protecting surrounding tissue while ink particles are targeted.
What does the term 'parallel cooling' mean in laser treatment protocols?
Answer: Applying cooling concurrently with each laser pulse to maintain continuous epidermal protection
Parallel cooling means the cooling device operates simultaneously with laser pulse delivery, providing continuous epidermal protection at the exact moment thermal energy enters the tissue.
