Key points about cuts, scratches and grazes
If your child has very serious bleeding including spurting blood, or they feel faint or light-headed then call 111 within New Zealand straightaway (use the appropriate emergency number in other countries).
- a clean cut or tear in the skin is called a laceration
- most lacerations are not deep and heal easily with self-care
- deeper lacerations may need stitches by a nurse or doctor
- a graze (or abrasion) is a scraping or rubbing away of the skin surface
- grazes are not deep and usually heal within 2 weeks with self-care
Managing your child's cut or graze
If your child has a cut or graze, follow these steps to help it heal well.
- wash your hands with soap and water before and after cleaning any wound
- if necessary use direct pressure to stop bleeding
- clean the wound with lukewarm tap water - use sterile saline solution if you have some in your first aid kit
- leave clean, loose flaps of skin in place to form a natural dressing
- apply antiseptic ointment (such as savlon or betadine) only if the wound is dirty – do not use for longer than 2 weeks
- cover with a non-stick dressing
- keep dry for 24 hours if possible during initial healing
- replace the dressing if it becomes dirty or wet
- check whether your child needs a tetanus injection - ring your GP practice if you are unsure
- a booster injection is recommended if it is more than 10 years since your child's last tetanus injection, or 5 years if the wound is dirty, contaminated or deep
