How to prevent cryogenic burns in winter?

Most of them are lower limbs with irregular erythema with thin and tight blisters.

Usually, the early symptoms are not obvious, and there may be slight burning and pain locally.

But it should be noted that:

For some specific people in low-temperature burns, such as diabetes, cerebrovascular accident patients, the elderly, etc., the skin sensitivity is abnormal, so after low-temperature burns, the injury can reach the degree of II and III burns, and often lasts for a long time.

How to reduce the risk of low-temperature burns?

Electric blankets, hot water bottles, electric fans and baby warmers in winter may cause cryogenic burns. Prevention from the source can effectively reduce the risk in cryogenic burns.

People who need special attention

Old people: limbs are insensitive and prone to low-temperature burns.

Patients with mobility difficulties, such as cerebral infarction and paralysis in bed, can't escape by themselves when they are in danger, and they are also vulnerable to low temperature burns.

Diabetic patients: The blood supply at the distal end of this kind of patients is poor, and most patients in the late stage often have sensory disturbance at the distal end of one limb, numbness of limbs, and tolerance to low-temperature burns.
