医生：长途旅行久坐要当心

Core Viewpoint - The incident involving a 19-year-old female student who suffered cardiac arrest after a 31-hour train journey highlights the risks associated with prolonged sitting during long-distance travel, particularly during peak travel seasons like the Spring Festival [1][2]. Group 1: Incident Details - The student, referred to as Xiao Ai, experienced a sudden loss of consciousness and cardiac arrest shortly after disembarking from the train at Dongguan East Station [1]. - Immediate actions taken by station staff included calling emergency services and performing basic CPR, which were crucial in saving her life [1]. - After six hours of intensive rescue efforts, including the use of ECMO life support, her condition stabilized [1]. Group 2: Medical Explanation and Recommendations - The condition that affected the student is known as "economy class syndrome," which is caused by prolonged sitting leading to blood clots in the lower limbs, potentially resulting in fatal pulmonary embolism [2]. - During peak travel times, factors such as prolonged immobility, inadequate hydration, and disrupted sleep patterns can trigger cardiovascular issues [2]. - Medical experts recommend that travelers should not ignore symptoms like chest tightness or dizziness, take breaks to walk every 1-2 hours, perform ankle pump exercises while seated, and stay hydrated by drinking 100-150ml of warm water every hour, while avoiding caffeine and alcohol [2].
