Although the heavy snowfall for several days can purify the air and protect the environment, it does bring a lot of inconvenience to the public to travel. Whenever such weather occurs, it is also a busy time for the emergency department of trauma surgery in the hospital, and the number of patients with fall injuries is significantly increased compared with previous days. According to the statistics, most of the fall patients are over 50 years old, and most of them have wrist and ankle sprains, and some of them have wrist fractures, patella fractures, hip fractures or lumbar spine injuries. Zhu Yuqi, orthopedic surgery department of the Eye Hospital of the Chinese Academy of Traditional Chinese Medicine Xinjiang Medical University Sixth Affiliated Hospital trauma orthopedic department Ren Zheng reminds us that rain and snow can lead to a high incidence of trauma, snow and ice will be more difficult to travel on the road, snow days fall prevention should pay attention to the following points: First, should try to reduce going out, the elderly should be more so, try to do a foot stop steady, solid, and then take the other foot, once alternately slow Walk slowly. Especially the frail and elderly people with mobility problems should be more careful and should be accompanied and supported when they have to go out. Second, you should pay attention to self-protection on the road, pay attention to obey the traffic rules, do not rush, and try to choose public transportation to travel. Third, clothing should not be too thin, thick clothes have a protective effect. Fourth, once the fall, pay attention to check the fall site for swelling, pressure pain, such as swelling should immediately seek medical attention, not at home to deal with their own to prevent delays. Fifth, to have a pair of non-slip shoes, so as to reduce the chances of falling, walking as far as possible to take the bare road, do not take the road with floating snow, it is likely that the following is the ice surface, will lead to falls. After a fall, people usually have a wrong practice, many people will subconsciously rub the injury, use blood medicine to smear the injury, think this can reduce pain, relieve the injury. This is not true, after the fall massage is not only not conducive to the recovery of the injury, and may even aggravate the injury, resulting in the emergence of local tissue congestion edema, if the original fracture risk of aggravating the injury or lead to fracture dislocation. The swelling of the injury indicates the rupture of small blood vessels and internal bleeding. The correct approach is to apply a local cold compress first to constrict the blood vessels and stop the pain and bleeding. After 24 to 48 hours, the swelling of the injury is reduced and the pain is relieved, then apply hot compresses, the swelling will slowly reduce, if there is persistent swelling and pain is not relieved, you also need to go to the hospital for examination and treatment.
