Healing a burn injury involves several steps depending on the severity of the burn: First-degree burns typically require cooling the burn under lukewarm water, covering it with a sterile, non-adhesive bandage, and using pain relievers. Second-degree burns may need more intensive care, such as cleaning and applying an antibiotic ointment to prevent infection before bandaging. Proper hydration and pain management are also critical. Third and fourth-degree burns require immediate medical attention. Treatment often involves the use of intravenous fluids, antibiotics, pain management, and potentially surgeries such as skin grafting or reconstruction procedures to heal the affected areas and restore function.
