Additionally, there is a comprehensive operating table located at the front of the vehicle. The middle of the vehicle is equipped with a central digital control screen. (3) First aid materials and instruments: the vehicle's materials are modularly configured in accordance with the resuscitation, guardianship, surgery, inspection and testing, Communication modular configuration, equipped with a defibrillation monitor, transfer ventilator, extracorporeal membrane lung oxygenation and other critical care first aid and electrocardiogram, digital radiography, blood gas analyzer, chest pain 5 monitors and other inspection and testing equipment; (4) Vehicle communication and information systems: equipped with high-definition remote video interactive system, telemedicine terminal DP300 integrated system, a real-time panoramic experience system and centralized guardianship system; (5) Vehicle disinfection: a plasma disinfector installed on the top of the car can meet the hospital disinfection hygiene standardsⅡ class environmental management requirements.Conclusions:Incorporating 5G communication technology, the large-scale mobile emergency resuscitation unit is equipped with various advanced treatment equipment and remote consultation systems. It can accommodate the resuscitation needs of the most critically ill patients, offering substantial support for public emergency rescues. Further exploration of its potential is merited.
RESUMO
Objective:To summarize the experience of ambulance medical support in the 19th Hangzhou Asian Games, and provide reference for the ambulance medical support work of large-scale sports events in the future.Methods:According to the actual situation of the Asian Games, the objectives of the medical support were determined according to the principles of highlighting the key points and overall consideration. All kinds of ambulances were allocated according to the principles of combining dynamic and static and regional linkage. The ambulance support was divided into the event side and the city side,with the regional security vehicle as the supplement of the event side and the guarantee of the city side, the implementation of "one pavilion one policy", "one game one policy", "one place one policy" and "one vehicle one plan", and the interconnection of medical points (rooms), designated hospitals, management and command personnel and ambulances were realized through the Asian Games Intelligent Emergency Medical Support Syetem (EMSS).Results:Between September 16, 2023, 08:00, and October 9, 2023, 08:00, a total of 207 ambulances were deployed during the 19th Hangzhou Asian Games. Of these, 88 (42.5%) were at competition venues, 11 (5.3%) at training venues, 30 (14.5%) at non-competition venues, and 78 (37.7%) were regional support vehicles. Among them, 20 venue ambulances participated in regional support tasks during idle times. Ambulances transported patients from event sites 345 times, with the highest number of transports occurring at competition venues (187 times) and the fewest in the assisting city of Huzhou (6 times). The highest ambulance utilization rate was 70.5% at competition venues, while training venues, non-competition venues, and regional support ambulances had utilization rates of 45.5%, 53.3%, and 42.3%, respectively. The median age of transported individuals was 26 (21, 36), with a majority being male (59.1%). Athletes comprised 52.5% of transports, while staff and spectators accounted for 39.7% and 7.8%, respectively. Joint injuries were the most common condition among transported individuals, totaling 58 cases (16.8%). Regional support ambulances participated in 75 transfers and replacements, with 17 (22.7%) transfers and 58 (77.3%) replacements.Conclusions:This study confirms the feasibility and efficiency of the Asian Games' ambulance support plan, highlighting the crucial role of EMSS. The study suggests the need to strengthen medical support for staff, in addition to athletes.
RESUMO
Objective:To construct an intelligent medical emergency information platform for the 19th Hangzhou Asian Games events and evaluate its practical application.Methods:Addressing the medical support demands for Asian Games, based on the " Emergency medical service system for large-scale social activities" developed by Zhejiang Laboratory, a collaborative team comprising Hangzhou Emergency Center, the Second Affiliated Hospital of Zhejiang University,Zhejiang Lab and College of Biomedical Engineering and Instrument Science of ZhejiangUniversity developed an intelligent medical emergency information platform for the Asian Games. This system was implemented during the 19th Hangzhou Asian Games, collecting basic information, initial diagnosis locations, prognoses, severity grading, and occurrences of infectious diseases for all patients treated at support locations from September 16th to October 8th, 2023. The Modified Early Warning Score (MEWS) was employed for assessing patient conditions, and a symptom monitoring system was used to alert the occurrence of infectious diseases. Post-event, a satisfaction evaluation (on a 5-point scale) regarding the system's application was conducted.Results:The successful construction of the intelligent medical emergency information platform comprised a data dashboard display platform, a comprehensive command system on the management center, and a mobile platform covering on-site medical support, ambulances, and designated hospitals. ①A total of 11 068 patients were treated using this system, including 2 979 athletes, 3 429 staff members, 1 421 volunteers,1 051 spectators, and 2 188 others. The proportion of patients seeking treatment due to illnesses was significantly higher than those due to injuries. Among injury-related cases, athletes constituted 41.37%, while staff accounted for 32.5% of illness-related cases. ②The area under the ROC curve for MEWS regarding hospitalization rates was 0.81 for disease patients and 0.60 for injury patients. ③ There were 211 reported cases of infectious diseases during the event, constituting 1.91% of all treated cases.④ Satisfaction ratings: User-friendliness scored 4.47, completeness of functions scored 4.28, data security scored 4.38, and data accuracy scored 4.49. Compared to traditional paper-based reporting methods, 98.11% of users found the system more convenient, 92.45% were satisfied overall, and the recommendation rating was 4.36.Conclusions:The study findings confirm the critical role played by the information platform in enhancing comprehensive, accurate, timely, secure medical support information dissemination for the Asian Games and in early warning and control of infectious diseases.
RESUMO
Objective: By analyzing the psychological state of patients during pre-hospital care,proper psychological support is provided for better rescue,reduce patients′ suffering and and incidence of medical conflicts.Methods: Follow-ups with patients of pre-hospital care,discussion of medical cases,and practical experiences are reviewed,and combine psychological knowledge and pre-hospital care.Results: When psychological support is given during pre-hospital care,patients′ pain was greatly reduced with satisfaction increased.Conclusion: The psychological support is given during pre-hospital care is necessary,and benefits both doctors and patients.
