Abstract：
BACKGROUND: The COVID-19 pandemic has introduced major changes in the resuscitation practices of cardiac arrest victims.
OBJECTIVE: We aimed to compare the characteristics and outcomes of patients who sustained in-hospital cardiac arrest (IHCA) during the early COVID-19 pandemic period (2020) with those during the late COVID-19 pandemic period (2021).
METHODS: This was a retrospective review of adult patients sustaining IHCA at a single academic centre. We compared characteristics and outcomes of IHCA for 5 months in 2020 with those experiencing IHCA for 5 months in 2021.
RESULTS: Patients sustaining IHCA during the early COVID-19 pandemic period had higher rates of delayed epinephrine administration of more than 5 min (13.4% vs. 1.9%; p < 0.01), more frequent delays in the initiation of chest compressions (55.6% vs. 17.9%; p < 0.01), and were intubated less often (23.0% vs. 59.3%; p < 0.01). In terms of outcomes, both return of spontaneous circulation (35.8% vs. 51.2%; p < 0.01) and survival to hospital discharge rates (13.9% vs. 30.2%; p < 0.01) were lower during the early COVID-19 pandemic period.
CONCLUSIONS: The early COVID-19 pandemic period was associated with delays in epinephrine administration and chest compression initiation for IHCA. Moreover, both return of spontaneous circulation and survival to hospital discharge were lower during the early COVID-19 pandemic period.

摘要：
背景：COVID-19大流行给心脏骤停患者的复苏实践带来了重大变化。
目的：我们旨在比较在COVID-19大流行早期（2020年）和在COVID-19大流行晚期（2021年）期间发生院内心脏骤停（IHCA）的患者的特征和结局。
方法：这是一项对在单一学术中心维持IHCA的成年患者的回顾性研究。我们比较了2020年5个月IHCA与2021年5个月IHCA的特征和结果。
结果：在COVID-19大流行早期维持IHCA的患者延迟服用肾上腺素超过5分钟的比率更高（13.4％vs.1.9%；p<0.01)，胸部按压开始时更频繁的延迟(55.6%vs.17.9%；p<0.01)，插管频率较低(23.0%vs.59.3%；p<0.01）。在结果方面,自发循环均恢复(35.8%vs.51.2%；p<0.01）和出院生存率（13.9%vs.30.2%；p<0.01）在COVID-19大流行早期期间较低。
结论：COVID-19大流行期的早期与IHCA的肾上腺素给药和胸部按压开始延迟有关。此外，在COVID-19大流行早期,自发循环恢复和出院生存率均较低.
