Children are active and prone to slight bumps. It is very necessary for parents to master the knowledge of external drugs for daily care. Band-aid is used for small superficial wounds with bleeding. Band-aid for clean, superficial and bleeding small wounds can protect the wound and stop bleeding. However, small and deep wounds should not be treated with band-AIDS, and it is best to send them to hospital for treatment. In addition, the band-aid also has the function of absorbing liquid. If it gets wet, it should be replaced immediately. Band-AIDS need to be updated every day. Complex iodine (iodophor) If the baby is bruised, scratched or scratched, first clean it with clear water (normal saline, unopened bottled purified water), and then dilute it with cold boiled water to pollute the wound with 10 times complex iodine. Mucosal wounds can also be used. Then dry it with a tissue. If the bleeding can stop by itself, the wound can be thoroughly cleaned with compound iodine. Don't cover the wound, and don't apply ointment to keep it dry. Yunnan Baiyao spray has the effects of promoting blood circulation, removing blood stasis, reducing swelling and relieving pain for acute soft tissue sprain and contusion, but children can't use it if their skin is damaged here, nor can they use it if they are allergic to alcohol. Children's skin is delicate, so it is best to spray aerosol on normal skin before using it without allergic reaction. In addition, don't use it when your face is injured, in case the medicine is sprayed into your mouth, eyes and nose. Votaline cream (Diclofenac diethylamine cream) After children sprain, strain and contusion, they should use a towel to apply cold compress first, and then use Votaline cream two days later to help him relieve the pain. If the skin is broken or an open wound cannot be used. This medicine will also be absorbed by the whole body when used locally, so don't use it in large doses. Children who are allergic to antipyretic and analgesic drugs should not use voltarin. Baiduobang Ointment (Mupirocin Ointment) If your child's small wound shows signs of redness and inflammation, you can use Baiduobang Ointment, which is an external antibiotic. It is used three times a day for five days as a course of treatment. When the wound around the eyes is inflamed, erythromycin eye ointment should be used instead of Baiduobang ointment.
