How to prevent and treat cold injuries during wind and snow drills?

In the past few days, from island fortresses with biting cold winds to snow-covered white mountains and black waters, the troops stationed there have moved upon orders to carry out actual combat training under severe cold conditions. The Shenyang Joint Logistics Support Center dispatched multiple medical teams to implement embedded accompanying support. At about 5 a.m., a combined brigade of the Army in the Northern Theater Command, which had just moved from a warm zone to a cold zone last year, braved the severe cold of minus 28 degrees Celsius and immediately entered combat mode.

Occupy positions, open passages, and attack breakthroughs... After a battle, the soldiers were already sweating and panting. Many soldiers even unbuttoned their coats and took off their neck collars, and the cold air soon invaded. Sweaty underwear. After a while, some soldiers felt that their whole bodies were tight and their faces were itchy and painful. Upon seeing this, Meng Bo, a military doctor from the dermatology department of the 211 Hospital of Shenyang Joint Logistics Support Center who was accompanying him for medical support, immediately suggested to the company commander Wang Boyan to organize a short break.

"Everyone, please fasten your camouflage coats quickly! Prevent heat dissipation too quickly, freezing the body, and causing systemic cold damage. Over time, the body surface temperature will decrease. When the body surface temperature is too low, it may Fainting." Upon hearing this, everyone quickly put on their cold camouflage coats. During the break, Dr. Meng conducted on-site training and guidance for the squad platoon leader: Under severe cold conditions, during combat drills, attention should be paid to rest, and measures such as wind protection and snow blindness should be taken; on alert and on duty, one should avoid standing still for long periods of time and rub hands and face frequently. , stomp your feet and flex and stretch your toes vigorously to promote blood circulation; when lurking in the wild, tighten your cuffs, trousers, and belts, and prevent snow from filling your shoes, so as to "seek movement in silence and use movement to prevent freezing."

"You guys stop, don't rub your hands and face with snow! That will cause frostbite to your hands and face..." Just after explaining the precautions to the squad platoon leader, the soldiers over there started again Made the habitual mistake of preventing frostbite. Doctor Meng immediately stopped the incident and educated the entire company on frostbite protection. He said that when rewarming frostbite first aid, it is strictly forbidden to use folk methods such as "cold water immersion, ice and snow rubbing, beating and massaging the frostbitten area". If the rewarming time is too long, the effect will be poor, and it is easy to get frostbite again; nor can Bake with open flames such as bonfires or stoves or soak in hot water with a temperature higher than 50 degrees Celsius. Overheating and rewarming will cause burns (scalds) in the frostbite area, aggravate tissue damage, and lead to serious consequences such as amputation. Do not drink alcohol to keep out the cold. Drinking alcohol can cause peripheral skin blood vessels to dilate and accelerate the body's heat dissipation. At the same time, drinking alcohol can also inhibit shivering and reduce heat production, resulting in slow reaction and possibly training accidents.

While marching, Doctor Meng gave extra lessons to the officers and soldiers. He said that the correct way to treat frostbite is to soak the frostbitten limbs in water at about 40 degrees Celsius for 20 to 30 minutes until the frozen limbs warm up and the skin of the fingers and toes becomes rosy. You can also use a wet towel of the same temperature to apply local heat, but not Rub and massage the frozen limbs. Frostbite ointment should be applied externally after rewarming. Those with particularly severe frostbite must be evacuated immediately for treatment. During training, if there is no warm water for rewarming, you can put your frostbitten hands and feet under your own or your comrades' armpits or abdomen to rewarm them, or you can wrap them in cotton clothes or sleeping bags to keep warm.

It is easy to get frostbite in the snowfields, and it is very difficult to protect yourself from the cold near the sea. It's been a cold day for several days. The temperature on the Bohai Bay is not very low, but the sea breeze is chilling to the bones. In the evening, a drill of officers and soldiers of the 210 Hospital Medical Team accompanying the team was in full swing. After the commander intercepted the information that the enemy's supply team was about to pass through the valley, he immediately ordered the team to choose a favorable position to prepare for an ambush. As a result, Private Xiao Wang was inexperienced and did not consider the wind direction when choosing a hiding position. A cold wind blew and scratched Xiao Wang's face. After lurking for less than half an hour, his sweaty feet became numb. When the enemy entered the ambush circle and the troops began to attack, Xiao Wang failed to rush out.

The accompanying military doctor Shi Jia immediately rushed to Xiao Wang's side, took off his sweat-soaked shoes and socks, then wrapped his feet in a dry towel and placed them on his abdomen to rewarm them for more than ten minutes. Xiao Wang had some feeling in his feet, and after a while, he slowly regained his ability to move. When they returned to the team, the military doctor told them that Xiao Wang's condition was very dangerous, commonly known as "trench foot". This is caused by long-term immobility or little movement in a humid and cold environment, which causes blood circulation disorders and causes non-freezing of the feet and calves. Cold injury. Therefore, even if you train in a place that is not particularly cold, you must prevent cold damage caused by cold wind. This requires us to wear cold-proof clothing correctly during training, change sweaty boots and socks in time, and not tie shoelaces too tightly, as too tight will affect blood circulation. After this kind of cold injury occurs, wet clothes, shoes and socks should be changed in time, and the feet should be wrapped in warm and soft clothes to rewarm.

The military doctor added that to prevent cold injuries, in addition to cold protection measures, scientific cold-resistant training is also required. In winter, insist on alternating "slow-fast-slow" long-distance running exercises, insist on outdoor activities for 6 to 7 hours a day, and insist on soaking hands and feet in cold water of 5 to 10 degrees Celsius for 10 minutes every morning and evening. If you persist in this way, your cold tolerance will be improved. Will improve
