At 5 a.m., it was still dark outside, and Li Yanli, a ski doctor, was woken up by an alarm. Without any delay, she quickly washed up, dressed up, and took the 6 o'clock shuttle on time to the National Alpine Ski Center, the highest altitude in all the venues of the Beijing Winter Olympics. "As the Beijing 2022 Winter Olympics have entered the final stage of preparation before the start of the games, the security staff has been fully motivated, and they have to go up the mountain very early every day to work, as a ski doctor, you must keep up with the pace of these behind-the-scenes heroes before the game and guard their safety." Li Yanli said, "When it comes to the game, we are likely to go up the mountain at 4 or 5 o'clock, and only before everyone arrives at the mountain point and returns after the last person goes down the mountain can we ensure that if an accident occurs, we can reach the injured person within 4 minutes." ”

After entering the closed loop of the Yanqing Division of the Beijing Winter Olympics, Li Yanli quickly entered the support work mode.

In 2018, because of her love of sports and a certain foundation in skiing, Li Yanli, who was the nurse in charge of Yanqing District Hospital at the time, was selected into the ski doctor team. According to public information, alpine skiing is the fastest sport in the Winter Olympics, especially in the racing race, the fastest speed of athletes rushing down from the top of the mountain can reach 140 km / h, and the injury rate is as high as 15% to 20%, which is not only the highest injury rate in the snow event, but also one of the most difficult medical rescue projects. Therefore, the goal of forming China's first ski doctor team is also very clear, that is, to create a "super guard team" on the Winter Olympic track through continuous and professional training.

Although she is a ski enthusiast, when Li Yanli began to carry a 20-kilogram rescue backpack and carried out emergency treatment in a strong wind, extreme cold, steep slope, and icy snow environment, the degree of difficulty was still unexpected. "In order to strengthen the business and make up for the shortcomings, in the past 4 years, the Winter Olympic ski doctors have to carry out at least 20 days of intensive training every snow season, and the training time is about 10 hours every day, and they must continue to summarize experience and lessons after the end."

Despite adequate preparations, when facing the "snow flying swallow" of the National Alpine Ski Center, Li Yanli said bluntly, "Finally understand why this is known as one of the most difficult alpine ski tracks in the world, in the field exercise, some tracks have a slope of 60 degrees, visually like a cliff, and there is no way forward." "Therefore, in the test match and closed-loop operation, Li Yanli and her teammates need to take a kneeling posture of one knee or both knees, stabilize themselves first, and then treat the injured," Such a way will cause certain damage to the knee, and we will seize the time to do moxibustion and plaster in normal times to avoid affecting the rescue work due to their own physical problems. According to another introduction, on the slope, many rescue actions are completely different from the flat land, taking cardiac resuscitation as an example, everyone's force is different, can not be operated according to the book, ski doctors must pass hundreds of exercises, in order to find out the right way for themselves.

Cold is another major obstacle to the treatment of snow-capped mountains. "First of all, when an athlete has an accident, we have to quickly take off the down jacket and thick gloves, light load, if the temperature is not less than minus 20 degrees Celsius at this time, ski doctors have long been accustomed to it, but many times the temperature is minus 30 degrees Celsius or even lower, the hands will be frozen, at this time if you want to accurately complete the intubation and other actions, for everyone's experience and technology have put forward higher requirements."

In addition, in order to prevent skin frostbite, ski doctors need to add a mask plus a layer of mask, then wear a helmet, and finally wear a protective face screen. "But another problem also arises, that is, when exercising, a lot of hot air is exhaled, and it is easy to make the face fog or even freeze, so we need to use tape to seal the mask and face tightly and try to avoid leaking up." Li Yanli said with a smile, "This is just a small case, after several years of preparation, we have started from scratch, we have broken through many obstacles, for China's ski doctors, to protect the Beijing Winter Olympics, there are always more ways than problems." ”
