摘要目的:总结2022年北京冬季奥运会（冬奥会）、冬季残疾人奥运会（冬残奥会）张家口赛区雪上项目中运动员所受创伤的特点及救治情况，以期为运动损伤的预防及冬季大型体育赛事的筹备提供经验。方法:回顾性收集张家口赛区闭环内医院（北京大学第三医院崇礼院区）在冬奥会、冬残奥会闭环期间（2021年11月21日至2022年4月5日）所有运动员的就诊记录，分析其创伤的发病率、严重程度、部位与诊疗经过。结果:张家口赛区共有1 188名冬奥会运动员与420名冬残奥会运动员参赛，其中冬奥会运动员创伤发病率为2.9%（34/1 188），冬残奥会运动员创伤发病率为1.7%（7/420）。运动员日均就诊量在冬奥会阶段最多（1.16例），就诊时急诊严重指数（ESI）评级均为3级（8例）或4级（33例），就诊科室中骨科最多（92.7%，38/41）。下肢受伤比例最高（53.7%，22/41），膝关节受伤占所有创伤的36.6%（15/41）。ESI 3级者大多采用支具固定（62.5%，5/8），ESI 4级者大多采用观察随访（57.6%，19/33）。41例运动员共做了57次影像学检查，单日被使用次数最多的影像学检查是X线片（5.00次），日均被使用次数最多的影像学检查是磁共振成像（0.16次）。运动员创伤患者的转运时间为（27.4±8.8）min，且多云、晴、小雪、阴4种天气的转运时间比较差异无统计学意义（ P=0.374）。 结论:张家口赛区冬奥会阶段的创伤发病率低于北京冬奥会与往届冬奥会，且无严重威胁生命的患者。张家口赛区的影像学检查资源与转运速度在冬奥会及冬残奥会的各阶段均能满足运动员的就诊需求。运动员在进行滑雪比赛时需注意下肢的防护。

abstractsObjective:To characterize the injuries suffered by athletes in snow events other than alpine skiing in the Zhangjiakou Zone of the Olympic Winter Games Beijing 2022, in order to provide insights for prevention of sports injuries and preparation of large-scale winter sports events.Methods:The medical records were retrospectively collected of all athletes who had been treated at Beijing University Third Hospital Chongli within the closed loop of the Zhangjiakou Zone during the Winter Olympics and Paralympics (from November 21, 2021 to April 5, 2022). The incidence, severity and part of the injuries were analyzed, as well as the medical treatment process.Results:In the Zhangjiakou Zone, a total of 1,188 athletes participated in the Winter Olympic Games, with an injury incidence of 2.9% (34/1,188), while 420 ones participated in the Winter Paralympic Games, with an injury incidence of 1.7% (7/420). The average daily medical visits were the highest during the Winter Olympics phase (1.16 visits per day), and their emergency severity index (ESI) ranged from level 3 to level 4. The department of orthopedics was visited the most (92.7%, 38/41). Lower limb injuries accounted for the highest proportion (53.7%, 22/41), with the knee ones accounting for 36.6% (15/41) of all injuries. Most of the athletes with ESI level 3 received splint fixation (62.5%, 5/8), while those with ESI level 4 mostly received observation and follow-up (57.6%, 19/33). A total of 57 radiological examinations were performed in the 41 athletes. X-ray was used the most frequently on a single day (5.00 times) while magnetic resonance imaging was per day on average (0.16 times). The transfer time for the athletes injured was (27.4±8.8) min which was not influenced by the 4 weather conditions (cloudy, sunny, light snow, and cloudy) ( P=0.374). Conclusions:The incidence of injuries during the Beijing Winter Olympics in the Zhangjiakou Zone was lower than that in other areas of the Beijing Winter Olympics and in previous Winter Olympics. There were no serious life-threatening cases. The imaging examination resources and transfer speed in the Zhangjiakou Zone were able to meet the medical needs of athletes at all stages of the Beijing Winter Olympics and Paralympics. Athletes should pay attention to protection of their lower limbs during skiing competitions.
