Cardiac arrest is common in critically ill patients with coronavirus disease 2019 (COVID-19) and is associated with poor survival. Simulation is frequently used to evaluate and train code teams with the goal of improving outcomes. All participants engaged in training on donning and doffing of personal protective equipment for suspected or confirmed COVID-19 cases. Thereafter, simulations of in-hospital cardiac arrest of patients with COVID-19, so-called protected code blue, were conducted at a quaternary academic centre. The primary endpoint was the mean time-to-defibrillation. A total of 114 patients participated in 33 "protected code blue" simulations over 8 weeks: 10 were senior residents, 17 were attending physicians, 86 were nurses, and 5 were respiratory therapists. Mean time-to-defibrillation was 4.38 minutes. Mean time-to-room entry, time-to-intubation, time-to-first-chest compression and time-to-epinephrine were 2.77, 5.74, 6.31, and 6.20 minutes, respectively; 92.84% of the 16 criteria evaluating the proper management of patients with COVID-19 and cardiac arrest were met. Mean time-to-defibrillation was longer than guidelines-expected time during protected code blue simulations. Although adherence to the modified advanced cardiovascular life-support protocol was high, breaches that carry additional infectious risk and reduce the efficacy of the resuscitation team were observed.
心脏骤停在患有 2019 年冠状病毒病(COVID-19)的危重病患者中很常见,并且与生存率差有关。模拟常用于评估和培训编码团队,以提高结果。所有参与者都接受了针对疑似或确诊 COVID-19 病例的个人防护设备的穿戴和脱卸培训。此后,在一家四级学术中心进行了 COVID-19 患者院内心脏骤停的模拟,即所谓的保护性编码蓝色。主要终点是除颤的平均时间。在 8 周内,共有 114 名患者参加了 33 次“保护性编码蓝色”模拟:10 名是高级住院医师,17 名是主治医生,86 名是护士,5 名是呼吸治疗师。除颤的平均时间为 4.38 分钟。平均进入房间时间、插管时间、首次胸部按压时间和肾上腺素给药时间分别为 2.77 分钟、5.74 分钟、6.31 分钟和 6.20 分钟;满足了 16 项评估 COVID-19 和心脏骤停患者适当管理的标准中的 92.84%。在保护性编码蓝色模拟期间,除颤的平均时间长于指南预期时间。尽管对改良的高级心血管生命支持方案的依从性很高,但仍观察到了一些违反规定的情况,这些情况会带来额外的感染风险,并降低复苏团队的效率。
