Management of Lip Lacerations in Children

Wound Care

Clean the wound with copious amounts of water or sterile normal saline to remove debris and reduce infection risk, ensuring the wound base is completely dry before any closure method is applied, as recommended by the American Academy of Pediatrics 1
For low-tension lip lacerations, tissue adhesive provides essentially painless closure, and the least amount of glue necessary should be applied to seal the wound 1
For wounds under high tension, consider sutures instead, and ensure adequate lighting to properly visualize the wound before beginning any procedure 1

The American Academy of Otolaryngology-Head and Neck Surgery recommends against prophylactic antibiotics for simple traumatic lip lacerations, and antibiotics should only be considered if there are signs of established infection 2

The European Society for Paediatric Anaesthesiology recommends acetaminophen at 60 mg/kg/day divided into four doses for adequate pain control, which provides effective analgesia while remaining well below toxic thresholds 3, 4, 5
Reassess pain regularly and adjust as needed, according to the European Society for Paediatric Anaesthesiology 4

The maximum lidocaine dose without epinephrine for children is 1.5-2.0 mg/kg, and for a 28.6kg child, the maximum dose would be 43-57mg of lidocaine 3

Keep lips moisturized with white soft paraffin ointment or petroleum jelly to prevent cracking as the wound heals, and encourage gentle oral hygiene with warm saline rinses, as recommended by the British Association of Dermatologists 6, 7

Instruct caregivers to watch for signs of infection, including increasing pain, redness, or swelling beyond the first 24-48 hours, purulent discharge, fever, and wound dehiscence, according to the American Academy of Pediatrics 1, 7

For mucosal-side lacerations, gentle cleaning with warm saline is sufficient and avoids tissue trauma, according to the British Journal of Dermatology guidelines 8

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 Journal of Dermatology 8
Encourage gentle oral hygiene with warm saline rinses after meals to keep the area clean, following the British Journal of Dermatology guidelines 8
Consider offering the child's favorite drinks for oral irrigation rather than standard mouthwashes to improve compliance, as suggested by the British Journal of Dermatology 8

Instruct parents to watch for warning signs including fever, according to the British Journal of Dermatology 8
Instruct parents to watch for warning signs including difficulty eating or drinking due to worsening pain, as recommended by the British Journal of Dermatology 8

Avoid adhesive dressings on or near the lips, as they can cause additional trauma when removed, according to the British Journal of Dermatology 8
Do not prescribe topical anesthetics for intraoral use in young children due to risk of accidental ingestion, as recommended by the American Academy of Pediatrics, based on information from Pediatrics 9
