Is the end of the snowfield orthopaedics?Emts run into a 70-degree Winter Olympics alpine course

“The end of the ski field is orthopedics”, Lin Rui, a skiing enthusiast, has recently flooded his moments with this sentence.After opening the plate last year, he “pleased” a radial fracture, hard resonance.For this reason, at noon on February 10, an athlete in the men’s all-around speed skating alpine skiing event suddenly ran out of the track and hit the fence, which made Lin Rui very frightened. “This is much more dangerous than the track we play.”The Swiss athlete was diagnosed with an open fracture of his left forearm by a medical officer on site and airlifted to a designated hospital for treatment.Ice sports are inherently risky.Winter games every spectator high competitive projects, whether can be more than 140 kilometers per hour of alpine skiing, GuAiLing turn left 1620 win the gold medal with the air freestyle ski jumping, or present in skating, speed skating, curling, where athletes are facing a big injury probability – according to the international Olympic committee (ioc),In recent years, the injury rate of athletes in the Winter Olympics is as high as 10%~14%.Combined with the prevention and control of COVID-19, this undoubtedly puts forward higher and more complicated requirements for the medical security of the Beijing Winter Olympics.How did Beijing respond to this huge challenge?Even after more than three years of training, especially skiing training, Chen Lu, a doctor from Beijing No. 3 Hospital, still has to do a lot of mental work every time she stands on the alpine skiing track of Xiaohaituo Mountain.The highest starting area of Xiaohaituo Mountain is 2198 meters above sea level, and the vertical drop of the whole track is nearly 900 meters.The maximum slope is close to 70 degrees over a slope length of more than 3 km.Instead of the powdery snow common to skiing, the course was filled with icy snow, making it “very difficult for ordinary people to stay on the track,” Chen lu told China Newsweek.During the three years of training, Chen Lu herself suffered more than one injury, including rib cartilage contusion and hip hematoma, and recovered for at least half a month each time.In the same group of dozens of ski doctors, hand contusions, twisted knee joints are the most common, clavicle, sternum fracture such serious injuries also happen from time to time.On this track, riders slide down at speeds of around 130km/h in the fastest sections, sometimes approaching 150km/h.Once an accident occurs, the severity can be imagined.There were more than one images of athletes being carried away from the alpine slopes at the Sochi Games.Chen Lu’s team of ski doctors is set up in the medical station next to the alpine ski track, and pays close attention to the movements of athletes who pass through this section at any time.When danger occurs, they must reach the injured person in the golden four minutes, then remove the skis and perform emergency assessments and treatment – such as fracture fixation, bleeding area dressing, pain relief, etc. – to set the stage for the next transfer of treatment. The whole process takes no more than 15 minutes.After the New Year’s day holiday, Chen Lu and her teammates went to the competition site by the designated closed-loop commuter bus, dressed in the winter Olympics uniform and carrying equipment.Day after day, Chen lu prepared heating gloves and other thermal devices to withstand the body temperature of minus 10 degrees Celsius, but it is impossible to wear them all the time on the track, because it will affect the flexibility of fingers during rescue operations.So frostbite can happen from time to time.Of course, the most important thing or back that 10 kg backpack, everything inside may be the injured need, including oxygen meter, stethoscope, blood pressure cuff, hemostasis kit, rescue scissors, pupil pen, elastic bandage, INTRAVENOUS infusion kit, simple breathing apparatus, etc..In contrast, yanqing surgeon Zhang Xuewen’s track rescue was easier.For one thing, the medical station he works at the National Snowmobile and Bobsled Center doesn’t employ doctors to challenge extreme sports like alpine skiing, and the environment is relatively friendly.On the other hand, there are more likely to be scratches and bruises, even moderate fractures, which the surgeons of these grade-A hospitals can handle with ease.”The most common part of our daily workload is dealing with non-sports injuries, such as stomach cramps, among athletes and staff, and sports injuries only account for about a third,” Zhang told China Newsweek.According to Wang Jianhui, deputy director of the Beijing Municipal Health Commission, 88 medical stations have been set up for the Beijing and Yanqing competitions, and 1,300 medical staff like Chen Lu and Zhang xuewen have been selected.Medical staff are an important part, but only a small part of the overall Olympic health care system.On the whole, the Beijing Winter Olympic Games has built a tiered medical and treatment system, from first aid at venues to newly built polyclinics in the winter Olympic village, and then to designated hospitals of several third-class a hospitals.In the middle of this system, the efficiency of the wounded is particularly important.In addition to regular ambulances and snow cats (tracked mobile ICU), yanqing’s alpine ski area is equipped with mountain rescue helicopters.The injured Swiss athlete was transferred from the arena to a designated hospital in just eight minutes, at least 32 minutes faster than the ground ambulance.According to Cui Guoqing, a professor at The Third Hospital of Peking University, it only takes four minutes for a helicopter to transport the skier from The Yunding Ski Resort in Zhangjiakou to a designated hospital.At the same time, some “black technology” has also contributed to the improvement of the efficiency of medical security for the event.For example, the “law enforcement recorder” worn by emergency doctors is only the size of a mobile phone. It can record the injuries of the injured and the treatment methods of the doctors in real time, which can not only enable the follow-up treatment staff to get first-hand information, but also avoid some unnecessary disputes, such as communication problems with the athletes’ team doctors.The Beijing emergency center has also equipped at least one 5G ambulance for each competition venue.In this seemingly non-special ambulance, the diagnosis and treatment data of the injured on the spot by emergency doctors can be directly transmitted to the designated hospitals, so that the critically ill patients can get remote guidance on how to deal with the situation of injuries, and realize “hospital admission immediately after boarding the car”.The smart mobile shelter, developed by Peking University Stomatological Hospital, acts as an emergency hospital for hockey venues.Its internal area is less than 20 square meters, but it has all the five organs — horizontal conical beam CT, portable intelligent CARDIopulmonary resuscitation machine, ecg monitor and other diagnosis and treatment equipment.Relying on artificial intelligence, big data and 5G, the intelligent mobile shelter can significantly shorten the time for medical decision-making.According to Peng Xin, a professor of oral and maxillofacial surgery at Peking University Stomatological Hospital, the AI diagnosis and treatment platform only takes 30 seconds to generate a report after an athlete receives a CT examination, which can buy a golden time for the injured.In the Winter Olympics clinic, a remote ultrasonic robot allows doctors to operate the robotic arm from thousands of miles away, completing real-time examination and diagnosis of patients within the closed loop, ensuring the quality of medical treatment.In addition to dealing with injuries, prevention of COVID-19 caused by the movement of people is also an important task for the medical security of the Beijing Winter Olympics.According to Wang, the Beijing Municipal Health Commission has divided winter Olymp-related patients into five categories, including confirmed and suspected COVID-19 patients, patients with fever in the closed-loop, patients with fever outside the closed-loop, and patients with other injuries and diseases outside the closed-loop. Different treatment mechanisms are available for different types of patients.In addition, Beijing has set up a team of 100 epidemiological investigation experts and a team of 3,600 personnel to quickly clarify the transmission chain and trace the source of the epidemic to ensure that the spread of the virus is cut off within the two longest incubation periods.The novel Coronavirus detection system of bioaerosol in public space, jointly developed by Tsinghua University, Peking University and Institute of Pathogen Biology, Chinese Academy of Medical Sciences, can collect and detect bioaerosol in the air.In particular, portable bioaerosol samplers in the venue are responsible for sampling, while automated, fully integrated and highly sensitive viral nucleic acid detection systems in the rear laboratories are responsible for analysis and generating test reports.According to an official from tsinghua University’s Medical School, the system can automatically detect results in 45 minutes without human intervention, and its sensitivity is at least 10 times higher than conventional methods, even for Omicron.Detection is available, so is elimination.This Winter Olympics, atomizing disinfection robot, ultraviolet disinfection robot, “small white” inspection robot also came in handy in the field tube.The “little white” in the tube can also interact with people: it can remind you to wear a mask, and stubbornly wait for you to put it on before leaving;Put your hand on the top of its head and get a dollop of hand sanitizer gel;It can also set up a countdown reminder before the game starts.All this preparation has only one goal: “to detect cases in the first place, to stop transmission, to stop the spread,” said McCloskey, the chief medical expert for the Beijing Winter Olympics.At present, such a goal, the Beijing Winter Olympics has preliminarily achieved.These “black tech” individual soldiers, as well as the overall coordination of the medical “team”, are still being tested in the ongoing Winter Olympics.The future of these medical technologies and experiences is much more exciting than the successful conclusion of an event.(Chen Lu and Zhang Xuewen are pseudonyms at the request of interviewees)
