The treatment of frostbite is mainly in prevention, paying attention to keeping warm and avoiding tight footwear, insisting on physical exercise to improve the body’s adaptability to cold, and strengthening nutrition by consuming more foods high in vitamins and protein. For local treatment, topical application of 10% camphor ointment, capsaicin ointment, glucocorticoid ointment or Xanax ointment can be applied directly to the unbroken lesions. For patients with rupture, 5% boric acid ointment, or 1% erythromycin ointment and moist burn cream can be used 2-3 times daily, with a healing time of about 10 days for the wound. Systemic treatment with oral cardiac painkillers 10-20mg three times daily for 10-20 days can release vascular spasm and promote blood circulation at the end. Niacin tablets 50-100mg, 3 times daily. Vitamin E 200mg, 3 times daily. Xibiling injection and pulsatilla injection can also be used as appropriate, both of which have the effect of dilating blood vessels and improving microcirculation.
