Management of Pediatric Lip Lacerations

Initial Assessment and Pain Control

Administer oral acetaminophen for systemic pain relief in pediatric patients with lip lacerations, as recommended by the American Academy of Pediatrics 1
Apply topical 2.5% lidocaine ointment cautiously to the wound edges, using sparingly to avoid accidental ingestion and systemic toxicity, following guidelines from the American Academy of Pediatrics 1
Avoid overuse of topical anesthetics, as accidental ingestion can lead to toxicity in young children, according to the American Academy of Pediatrics 1

Clean the wound with warm saline using gauze or an oral sponge, as recommended by the British Association of Dermatologists and the American Academy of Pediatrics 2, 1

Use a vertical incision approach for lesions traversing both vermilion and cutaneous tissues, as suggested by the American Academy of Pediatrics and the American Academy of Pediatric Dentistry 3, 4
Use a transverse mucosal incision to hide the scar at the junction of the vermilion and vestibular mucosa, following guidelines from the American Academy of Pediatrics and the American Academy of Pediatric Dentistry 3, 4

Apply white soft paraffin ointment to the lips every 2 hours during the acute healing phase to prevent drying and cracking, as recommended by the British Association of Dermatologists and the American Academy of Pediatrics 2, 5
Lubricate lips with lip balm or petroleum-based ointment frequently, following guidelines from the American Academy of Pediatrics 5, 4
Clean the mouth daily with warm saline mouthwashes, as suggested by the British Association of Dermatologists and the American Academy of Pediatrics 2, 1
Maintain oral hygiene with a soft toothbrush and mild fluoride toothpaste, according to the American Academy of Pediatrics and the American Dental Association 5, 4
Avoid irritants including spicy foods, hot foods and drinks, and citrus fruits, as these delay healing, as recommended by the American Academy of Pediatrics 5, 1, 4

Ensure adequate hydration, as painful lip injuries may cause children to resist drinking, according to the American Academy of Pediatrics 1
Offer soft, bland foods at room temperature during the healing period, following guidelines from the American Academy of Pediatrics 5, 1
For infants, nursing care is important as adjunct therapy, as suggested by the British Association of Dermatologists 2

Refer to a plastic surgeon or oral surgeon for bulky lesions causing lip lengthening that require wedge excision, as recommended by the American Academy of Pediatrics and the American Academy of Pediatric Dentistry 3, 4

The American Academy of Pediatrics recommends applying topical anesthetic immediately upon arrival to minimize procedural pain and anxiety, using LET solution with dosing of 3 mL for children >17 kg and 0.175 mL/kg for children <17 kg, with contraindications including allergy to amide anesthetics and grossly contaminated wounds 6
Topical anesthetic should be allowed 20-30 minutes for wound edges to blanch, indicating adequate anesthesia, with precautions to avoid overuse and accidental ingestion 6

For simple, low-tension lacerations without vermilion border involvement, the American Academy of Pediatrics suggests using octyl cyanoacrylate tissue adhesive or Steri-Strips for essentially painless closure, or consider absorbable sutures to eliminate pain and anxiety of suture removal 6

If additional anesthesia is needed after topical application, inject lidocaine using pain-minimizing techniques, such as buffering with bicarbonate, warming the solution, using a small-gauge needle, and injecting slowly, as recommended by the American Academy of Pediatrics 6
