| 1 | Cardiopulmonary resuscitation and termination of resuscitation on out-of-hospital cardiac arrest in China显示文摘To the Editor: Out-of-hospital cardiac arrest (OHCA) is a major public health challenge. Early initiation, good quality cardiopulmonary resuscitation (CPR), and the use of an automated external defibrillator (AED) have been reported to significantly improve the survival and long-term outcomes in survivors of OHCA. | Xiaojun He Yang Liu Sijia Tian Jun Liang Shengmei Niu Jinjun Zhang | 2022 | Chinese Medical Journal2022，，9： | 2 |
| 2 | Association between duration of return of spontaneous circulation and outcomes after out-of-hospital cardiac arrest显示文摘Background:Return of spontaneous circulation(ROSC)is a core outcome element of cardiopulmonary resuscitation(CPR);however,the definition or criterion of ROSC is disputed and varies in resuscitation for out-of-hospital cardiac arrest(OHCA).Methods:This was a retrospective study of 126 patients with OHCA who achieved ROSC between January and December 2020.The probability of survival after OHCA related to CPR and ROSC duration was analyzed using the probability density function and empirical cumulative density functions.Results:There were no significant differences between ROSC sustained until emergency department arrival and that sustained for at least 20 minutes in terms of the 24-hour survival rate(31.3%[31/99]vs.35.7%[10/30];P=0.84),30-day survival rate(23.2%[23/99]vs.25.0%[7/30];P=0.99),or survival at 30 days with cerebral performance category(CPC)1 and 2(18.2%[18/99]vs.10.7%[3/30];P=0.44).The Kolmogorov-Smirnov test values from the empirical cumulative density functions with ROSC sustained until hospital arrival and that sustained for at least 20 minutes were 0.44,0.20,and 0.24 for CPC 1 or 2,CPC 3 or 4,and CPC 5,respectively.Conclusion:Return of spontaneous circulation is a core outcome element of CPR.It should be defined as sustained for at least 20 minutes or until arrival at the emergency department and as a basic standard for evaluating resuscitation success after OHCA. | Huixin Lian Andong Xia Xinyan Qin Sijia Tian Xuqin Kang Luxi Zhang Shengmei Niu Fei Qin Jinjun Zhang | 2022 | Emergency and Critical Care Medicine2022，2，4： | 1 |
| 3 | Effects of a closed-loop system against SARS-CoV-2 at the Beijing 2022 Olympic Winter Games:a descriptive and modeling study显示文摘BACKGROUND:To assess the efficacy of the epidemic prevention measures of the“closed-loop”system adopted by the Beijing 2022 Olympic Winter Games(BOWG).METHODS:We retrospectively collected and analyzed information,including age,sex,nationality,vaccination status,date of diagnosis,and date of entry,from 280 SARS-CoV-2-positive individuals identified during the BOWG.A susceptibility-exposed-infectious-remove model was employed to evaluate the effectiveness of epidemic prevention strategies on controlling the spread of SARS-CoV-2 under different scenarios during the BOWG.RESULTS:Regarding SARS-CoV-2-positive cases,97.9%were imported,and 96.4%were asymptomatic.The median age was 37 years(range:29–47 years),and 73.9%were male,with the majority of cases being broadcasters and European attendees.Regarding vaccination status,93.5%were fully vaccinated,and six cases were considered to have been infected in the closed-loop system during the BOWG.Assuming that the BOWG adopted a semi-closed-loop management system,the cumulative number of confirmed cases would be 1,137 for quick quarantine measures(3 d later)implemented and 5,530 for delayed quarantine measures(9 d later)implemented.This modeling revealed that stringent pandemic prevention measures and closed-loop management effectively controlled the spread of SARS-CoV-2 during the BOWG.CONCLUSION:Imported cases are considered the main risk factor for SARS-CoV-2 transmission during mass gatherings,but a comprehensive closed-loop system could minimize transmission among attendees and general personnel. | Rong Xiong Jieping Zhou Wenning Li Jie Liu Jing Lou Sijia Tian Huixin Lian Shengmei Niu Luxi Zhang Wenhang Li Jinjun Zhang | 2023 | World Journal of Emergency Medicine2023，14，6： | 0 |
