Ski safety in the snow season

Skiing has become a common winter recreation project. The successful bid for Winter Olympics has attracted most snow fans to participate in skiing in winter. However, this sport is more likely to be injured, and even accidents are caused by various kinds of falls caused by skiing and broken bones in the snow. Therefore, it is necessary to have some methods for self-rescue and mutual rescue.

If you want to avoid injuries to the maximum extent, you should pay attention to the following seven matters before skiing.


First, beginners to find a teacher


It is best for beginners to find a technically skilled coach or peer coach, and then to go alone after mastering the essentials.


Second, do not forget to do warm-up exercises


Preparatory activities can increase the excitability of the central nervous system, increase the temperature of the muscles, unblock the blood circulation, increase the flexibility and range of motion of the joints and ligaments, and then slip after a preparatory activity, which is generally not easy to fall.


Third, clothing warm and agile


Wearing clothing is both warm and helpful. This is convenient for activities, conditional wear can be worn on the knee, wrist, can play a protective role. When the climate is particularly cold, wear gloves and earmuffs. After the exercise, wipe away sweat and put on clothes to prevent colds and frostbite.


Fourth, science falls to be remembered


When the body falls out of balance and falls, bend the body immediately to reduce the center of gravity. When you fall, you need to gather your limbs so that you can avoid or reduce your fall.


Fifth, dangerous actions must not be


Do not behave dangerously and interfere with others' actions. Do not place sharp objects such as nail clippers or knives, or fragile glass vials in your pocket or waist to prevent falling.


Six, bring some common drugs


Before leaving, it is best to bring some essential medicines and learn some first aid knowledge. Sterile dressings (gauze and gauze pads, etc.), bandages, bandages, etc. can be prepared. If you have a cold, you can take some hot cold granules, Banlangen granules. Once inadvertently sprained the joints, can be a good use of fast, bruises, or external application of Huoxiang Zhuanggu cream, internal bladder beaten pills, 37 tablets, Yunnanbaiyao capsules, etc., can relieve pain and swelling.


Seventh, the ability to choose the snow lanes


When you first arrive on the ski resort, you should first understand the approximate conditions of the ski resort. You should carefully understand the height, slope, length, width and surrounding conditions of the ski slopes, and select the appropriate ski slope according to your ski level. Familiar with the terrain, the location of the snow facilities, the rescue situation, and strict compliance with the safety regulations of the ski resort. Pay attention to the opening time of the ropeway and do not ride when you are not watching.


In addition, although the snow is relatively soft, but the general ski site is sliding from high to low, the impact is great, in the event of an accident, the damage will be very serious. If the pain is severe after a fall, you must not immediately get up and move. You should call for help nearby. If you have severe back pain, you should call an emergency number for professional help.


"Trauma should prevent further infection"


Frequent injuries often occur in wounds. External bacteria and foreign substances can easily enter the wound, causing infection, and there is more bleeding when blood vessels are injured. This can also cause shock to the injured. Therefore, after the occurrence of a wound, it is necessary to prevent further infection of the wound and stop bleeding in time.


Regardless of the condition of the wound, the position, size, degree of contamination, and damage to the blood vessels, muscles, tendons, and fractures must be carefully determined before treatment. So that different wounds can be treated differently.


In general, the wound is shallow, there is no nerve damage to the blood vessels, and it is easy to stop bleeding. If conditions permit, the wound can be flushed with saline, and the skin around the wound is disinfected with 75% alcohol, taking care not to let alcohol enter the wound. Then sterile dressings are bandaged. If there were no conditions at that time, the wound could be compressed with clean cloth, towels, clothing, etc., and then transferred to the hospital for treatment.


Head injury is more common. Once the head has a wound, use a sterile gauze or a clean cloth to stop the bleeding as soon as possible. When bleeding is heavy, hand-pressing for about 15 minutes can stop bleeding. Fingers are the most common ones. They can be bandaged directly after injury and can play a role in stopping bleeding and inflammation. Note that when using a band-aid, don't wrap it in a loop, which will cause finger ischemia. The correct approach is to spiral around the fingers. In addition, the band-aid should not be wrapped too tight, too tight oppression of the finger veins but not easy to stop bleeding.


"Accidents first determine whether or not fractured"


In the event of an accident, it should first determine whether the fracture, mainly to see whether the subcutaneous bleeding, deformity, bone fricative, swelling and abnormal (non-joint) movement and other phenomena. If the initial judgment is likely to be a fracture, it should be immediately fixed with a splint. If there is no splint, it can be fixed with a book or the like. Otherwise, the blood vessel will be deformed. Moreover, doing so without harm is not bad.


Clavicle fractures are generally deformed with clavicles, hematomas, and pain during shoulder movements. At this time, the stimulation of the fracture site should be minimized so as not to damage the subclavian vessels, and only the upper arm can be suspended by the triangle. If no scarf can be used instead of a scarf.


Upper arm fractures can cause upper arm swelling, blood stasis, pain, deformity during activity, and upper limb activity is limited. The plywood can be used to put the back side first, then the front side, and finally the inner and outer splints, and then use four bandages or 2-3 triangles.


The fractures of the forearm are divided into iliac bones or ulnar bones, or double fractures of the ulna and ulna, and there is no joint motion during the movement and the deformity appears. Forearm fractures have little chance of damage to the vascular nerves. They can be used with small splints or with two pieces of wood on top and bottom. The elbows are suspended 90 degrees from the chest. Book pads can also be used to lift the forearm directly under the forearm.


Femoral fractures cause swelling, pain, deformation, or shortening of the thighs. If conditions permit, a long splint can be used from underside of the armpit to the heel, a short splint from the inside of the thigh to the heel, and the other leg and the injured limbs together, and then fixed with seven wide bands, fixed at the knee joint and ankle joint. Place a cotton pad on the protruding part of the bone, and fill the space with soft items.


The symptoms of lower leg fractures are bleeding, swelling, and should not be fixed too tightly during fixation. At the same time, the pad should be protected by a thick pad. When using splints, it is best to use five splints if only two pieces of wood are placed on the inside and outside of the injured leg.


Spinal fractures occur in the cervical spine and thoracolumbar vertebrae, so a fracture is suspected. In particular, when the spine is fractured, the injured person must not try to walk, and the person handling spinal fracture must use wood to prevent the spinal cord injury from increasing. Otherwise, once the fracture block is displaced and the spinal cord is damaged, damage to the cauda equina will cause paralysis.


One of the cervical spine fractures is to wrap the collar around the neck to prevent cervical activity; the second is to use a newspaper, towel, clothing and other rolls to make a neck sleeve, and then enclose the neck from behind the neck. Neck thickness should be able to limit bilateral jaw activity.


Thoracolumbar vertebral fractures can be conditionally fixed with a board that is similar in length and width to the injured person's height and shoulder width. When the person is fixed, the injured person should lie on his/her side, and the movement should be gentle, and the body's long axis should be kept consistent from beginning to end. The head, neck, ankles, and cavities behind the waist should be cushioned. In addition, the injured shoulders, pelvis, legs and feet should be fixed with broadband before being transported to the hospital to avoid bumps and shaking.
