Whether the blister can heal itself, and the size of the blister related to the scalding. If the scalded blister is small, 1-2cm in diameter, it is possible for the blister to heal itself without picking it up, because the body has the ability to absorb the tissue fluid in the blister, and the blister skin can also act as a biological dressing to protect the wound, reduce pain, and facilitate wound healing. However, if the scald area is large and the blister area is also large, the body has a limited ability to absorb, usually without picking through the blister for fluid drainage, disinfection and other operations, the possibility of self-healing is very small. It is important to note that, in either case, the first means of treatment is not to pick the blisters after being scalded, but to rinse or soak with cold water, and pay attention at this time to protect the blisters from damage, and then according to the size of the blisters to deal with. 1, small blisters: do not pick, the affected area coated with scald cream, silver sulfadiazine ointment, erythromycin ointment, with clean gauze or band-aids for bandaging treatment That is, pay attention to the elasticity to be moderate, to avoid excessive squeezing blisters. Blister fluid will be gradually absorbed by the body, generally 1-2 weeks can be self-healing. 2, blisters larger: whether or not to pick broken, the possibility of self-healing is very small. This situation is not recommended to deal with themselves, need to promptly seek medical attention. After seeking medical attention, the doctor will use an empty needle to draw out the tissue fluid within the large blister, and then carry out local debridement, disinfection and bandaging. If the blister is inadvertently broken, the broken blister skin should be cut off, the broken area should be cleaned and disinfected, and the affected area should be wrapped with liquid paraffin gauze or petroleum jelly gauze with even pressure. If the burn is large, the doctor can also prescribe some antibiotics to avoid infection and use silver sulfadiazine ointment for topical application.
