This question is answered by the Deputy Chief Physician Li Xiaolin from the Emergency Department at Ganzhou People's Hospital, contracted through PureHealth. How long does it take for swelling to subside after a burn? The duration depends on individual constitution and the measures taken after the burn. It also greatly relates to usual diet and other factors. If the burn is mild and not very obvious, it can be resolved relatively quickly with standard treatment. However, if the burn is severe and covers a large area, and if swelling is also significant, the swelling is relatively difficult to reduce and will take a longer time to subside. Inappropriate treatment can lead to worsening of the condition and further complications. Therefore, immediate measures should be taken when a burn occurs: - Rinse with cold water for at least half an hour or until the pain subsides mainly. - Thoroughly disinfect with iodine to alleviate symptoms and slow the progression of the condition. Additionally, be cautious with your diet by avoiding spicy and stimulating foods, seafood, and inflammatory foods. For free expert consultation, please search PureHealth.

Should blisters from burns be punctured?

Whether to prick a blister caused by a burn depends on the size of the blister. For smaller, dense blisters, it's generally not necessary to break them, as the fluid can be absorbed naturally. However, it's important to keep the wound clean to avoid secondary injury, and topical burn ointment can be applied. For larger blisters caused by burns, or those with high tension that interfere with daily activities or life, and are difficult to absorb, you can sterilize the area and then use a sterile needle to puncture the base of the blister to drain the fluid. Be sure to thoroughly clean out the fluid inside the blister. However, the blister skin should be kept intact to cover the skin, providing protection, reducing the risk of infection, and promoting recovery.

How to treat baby's burns with blisters

If the burn has just occurred, first ensure the baby is quickly removed from the heat source, and soak the affected area in running tap water or cold water for over half an hour. Alternatively, a cold towel can be used to moisten and cover the wound, which can reduce the thermal damage to the burn area and minimize the formation of weeping wounds. If the blistered area is small, a moisturizing burn ointment can be applied. If there are small blisters, they may be left untreated, but do not break them; this maintains a sterile environment and allows the blister to absorb slowly. However, if it is a large burn area, it is necessary to seek immediate medical attention at a nearby burn unit for proper dressing and treatment of the burn. Additionally, care should be taken to avoid squeezing the burned area and to prevent the wound from getting wet.

What should I do if my finger swells up from a burn?

After a finger burn, it should immediately be rinsed with cold or running water continuously for at least half an hour to cool down the damaged skin. Then, use iodine or alcohol to disinfect the area, followed by covering it with a dressing. If swelling occurs, cold packs with ice water can be applied. Alternatively, magnesium sulfate wet compresses or more traditional remedies, such as continually applying potato slices, can help reduce the swelling. However, these methods will require some time to take effect. The main goal is to alleviate symptoms through anti-inflammatory and pain relief treatments, allowing the inflammation of the soft tissues to subside gradually and the swelling to reduce.

How long will it take for a burn on the finger to heal?

How long it takes for a finger burn to improve depends on the severity of the burn, and one cannot generalize. If the burn affects only the epidermal layer, recovery or complete healing generally takes about a week. This is because skin metabolism, which takes about 5 to 7 days to renew, especially at burned areas such as on the face or fingers, can take longer to heal. Moreover, if the burn is deeper, reaching below the dermal layer, the recovery time depends on how deep the burn is. It might take 2 weeks or even up to a month for complete recovery. Therefore, the duration needed for a burn to heal depends on the severity of the burn.

Can iodophor be used to disinfect burns?

After a burn, it is possible to disinfect with povidone-iodine. Povidone-iodine has a broad spectrum of antibacterial effects and can kill proliferating bacteria, fungi, and some viruses. After a burn occurs on the skin, the first step is to reduce the temperature of the skin, which can be done by soaking in running tap water or cold water for more than half an hour to alleviate pain. Then, disinfect with povidone-iodine. After disinfecting with povidone-iodine, apply burn moistening cream locally, and then wrap it with sterile gauze. Change the dressing once a day, and after dressing, try not to come into contact with water to prevent infection. Also, avoid friction between the wound and the gauze, as this could affect the healing of the wound. Generally, mild burns can heal in about two weeks.
