What should be applied when hands are swollen from firecracker burns?

Items commonly used to wipe the hands after a firecracker injury causing swelling include povidone-iodine, safflower oil, Yunnan Baiyao spray, anti-swelling and analgesic tincture, and medical alcohol (for intact skin only). Detailed explanations are as follows:

1. Povidone-iodine: If there is no obvious skin break or only minor abrasions, applying povidone-iodine helps clean the skin and prevent bacterial infection. It has low irritation and forms a protective film on the skin surface, preventing infection from worsening the swelling and discomfort.

2. Safflower oil: Suitable for cases of hand swelling without skin damage. Apply an appropriate amount to the swollen area and gently massage to promote absorption. It helps promote blood circulation, remove blood stasis, reduce swelling, and relieve pain, thereby alleviating local congestion and discomfort. Avoid contact with damaged skin.

3. Yunnan Baiyao Spray: This product consists of two parts—an emergency coolant spray and a main agent. If swelling is accompanied by significant pain, first spray the coolant to quickly relieve severe pain; wait three minutes, then apply the main agent. This combination helps reduce swelling, resolve blood stasis, and alleviate inflammatory reactions. It is ideal for noticeable hand swelling but must be avoided on broken skin.

4. Anti-swelling and Analgesic Tincture: Apply a small amount to the swollen area. The medicinal ingredients penetrate the skin to reduce swelling, relieve pain, and promote blood circulation, improving local blood flow and accelerating the resolution of swelling. Ensure the skin is intact before use to avoid irritating open wounds.

5. Medical Alcohol (for intact skin only): If the hand is only red and swollen without breaks in the skin, use a cotton swab dipped in medical alcohol to gently wipe the skin around the swollen area for disinfection. However, due to its strong irritancy, alcohol should not be applied to damaged skin or over large areas to prevent discomfort.

After a hand injury from an explosion, first check for any residual foreign objects or skin damage. Seek immediate medical attention if the wound is deep, bleeding does not stop, or if swelling progressively worsens, accompanied by numbness or restricted movement.
