What to do for skin injuries caused by firecracker explosions
Generally, the management of skin injuries caused by firecrackers mainly includes emergency wound cleaning, hemostasis and protection, topical medication, dressing and immobilization, and medical observation. The specific procedures are as follows:

1. Emergency Wound Cleaning
After a blast injury, gunpowder particles, debris, and other foreign bodies may remain on the skin. If not promptly removed, they increase the risk of infection. The wound should be gently irrigated with normal saline or running water for at least 15 minutes to ensure that foreign materials are washed away. Avoid rubbing the wound vigorously during irrigation, as this may worsen tissue damage.
2. Hemostasis and Protection
If the wound is bleeding, prompt hemostasis is necessary. For minor oozing, apply direct pressure using sterile gauze for 5 to 10 minutes. In cases of heavier bleeding, a tourniquet may be moderately applied proximal to the wound (closer to the heart), but it should be loosened every 30 minutes for 1 minute to prevent ischemic tissue necrosis. Keep the wound clean throughout to avoid secondary contamination.
3. Topical Medication
After cleaning and controlling bleeding, apply medications to prevent infection and promote healing. Topical agents such as mupirocin ointment, fusidic acid cream, or recombinant human epidermal growth factor gel may be used under medical guidance. Ensure hands are clean before application, and monitor the wound for abnormal reactions such as redness, swelling, or discharge after medication.
4. Dressing and Immobilization
Small wounds can be protected with sterile adhesive bandages. Larger wounds or those located near joints should be covered with sterile gauze dressings. The dressing should be firm but not too tight—ensuring no active bleeding while maintaining normal sensation in the limb. Minimize movement of joint areas after dressing to prevent loosening or reopening of the wound, which could impair healing.
5. Medical Observation
Seek immediate medical attention if the wound is deep, contains unremovable foreign bodies, or shows signs of infection such as redness, pus, or fever. A healthcare provider will perform professional debridement, administer tetanus antitoxin, and adjust treatment as needed to prevent serious complications like sepsis due to delayed care.
In addition, keep the wound dry and clean during recovery. Avoid contact with dirty water or contaminants. Limit intake of spicy and irritating foods, and consume more protein-rich foods to support healing. Strictly follow medical instructions for medication and attend regular follow-up visits to ensure proper wound healing. Return for re-evaluation promptly if symptoms such as increased pain occur.
