Topical lidocaine, epinephrine, and tetracaine (LET) gel is effective for repairing children's facial and scalp lacerations. Further research is needed for bupivacaine-epinephrine topical preparations.

Area of Science:

  • Pediatric Emergency Medicine
  • Dermatology
  • Anesthesiology

Background:

  • Primary care physicians require effective topical anesthetic options for minor pediatric procedures.
  • Literature review is necessary to assess the efficacy and safety of available agents.

Purpose of the Study:

  • To review topical anesthetic options for primary care physicians.
  • To evaluate indications, efficacy, and safety of topical anesthetics for pediatric laceration repair.

Main Methods:

  • Systematic review of five randomized controlled trials.
  • Comparison of various topical anesthetics and topical versus infiltrative anesthesia.

Main Results:

  • Lidocaine, epinephrine, and tetracaine (LET) gel is the preferred topical anesthetic for simple pediatric facial and scalp lacerations.

  • Bupivacaine-epinephrine shows promise but requires larger studies.
  • EMLA is not recommended for extremity lacerations pending further research.
  • Tetracaine, adrenaline, and cocaine (TAC) is not recommended due to cost, restrictions, toxicity, and availability of alternatives.

    • Conclusions:

    • Topical LET gel provides safe and effective anesthesia for children's simple facial and scalp lacerations.
    • Adherence to dosing and avoiding mucous membrane contact is crucial.
    • Bupivacaine-epinephrine warrants further investigation as a promising analgesic.
