Lidocaine for Scalp Laceration Repair

Administration Options

• The American Academy of Dermatology recommends topical lidocaine as a first-line method of anesthesia for the repair of dermal lacerations, particularly for face and scalp wounds, due to its equivalent efficacy to infiltrated anesthetics with less patient discomfort 1
• Lidocaine patches (4% OTC or 5% prescription) may be more effective than cream or ointment formulations as they deliver the medication gradually, according to the Mayo Clinic 2

Safety Considerations

• The American Heart Association and other guideline societies imply that monitoring for signs of local anesthetic systemic toxicity is crucial, which can include perioral numbness, tinnitus, metallic taste, visual disturbances, confusion, seizures, and cardiovascular collapse 3
• It is recommended not to exceed maximum recommended doses based on patient weight to avoid toxicity 3

Special Populations

• The American Academy of Dermatology strongly recommends topical agents as the first-line method of anesthesia for laceration repair in pediatric patients 1
• Topical lidocaine is particularly effective for face and scalp wounds due to higher absorption in these areas, as noted by the American Academy of Dermatology 1
