Should erythromycin ointment be used on frostbite wounds?

Generally, whether to use erythromycin ointment on frostbite wounds depends on the condition of the wound. It is not necessary if the skin is intact and there are no signs of infection; however, it should be used if the skin is broken, if there is a risk of infection, or if infection has already occurred. The details are as follows:

If the frostbite injury only presents with redness, itching, and mild swelling, without skin breakdown, exudation, or pus formation, erythromycin ointment is not required. Keeping the wound clean and dry and avoiding scratching will allow natural recovery. Blindly applying ointment may interfere with normal skin healing.

If the frostbite wound involves broken skin, is at risk of infection due to exposure to contaminants, or shows signs of infection such as fluid discharge, increased redness and swelling, or pain, erythromycin ointment should be applied. This ointment has antibacterial properties that help prevent or control bacterial infection. Before application, clean the wound thoroughly and apply an appropriate amount of the ointment to the affected area to prevent infection and promote healing.

In daily care of frostbite wounds, avoid getting the wound wet, minimize friction and irritation, and do not puncture blisters arbitrarily. Monitor the wound closely; if signs of infection do not improve or worsen after using the ointment, seek medical attention promptly to ensure proper healing.
