Children with swollen centipede bites should be treated immediately by treating the wound, reducing swelling and pain, and anti-allergy treatment. 1. Treating the wound: If a centipede bite is swollen, if there are venomous fangs left in the wound, they should be removed first. The venom is usually acidic. After being bitten, the wound can be washed repeatedly with alkaline solutions such as soapy water and soda in order to weaken the toxicity. 2. Reduce swelling and pain: cold towels can be used to apply wet compresses to the wound for about 20 minutes to change the towel, which can help reduce swelling and pain, and be careful not to apply cold compresses for too long. 3. Anti-allergy treatment: for mild cases, oral antihistamine medication can be taken, such as loratadine, etc. Antihistamines such as loratadine, through the antihistamine effect, can release the allergens, thus relieving allergy-related symptoms; for severe cases, anaphylactic shock occurs, and it is necessary to go to the hospital immediately for treatment. If a child is swollen by a centipede bite, it is recommended to go to the hospital in time for treatment under the guidance of a doctor.
