Norwegian critical care resources are regionalized making air ambulances transport of suspected or confirmed coronavirus disease 2019 (COVID-19)-positive patients a necessity. We prospectively observed pre- and interhospital transportation of patients with suspected or confirmed COVID-19 in our physician-manned emergency medical services.
This was a prospective, observational quality assurance study of primary and secondary missions conducted by 2 Norwegian air ambulances during the COVID-19 pandemic.
Forty-one (24.1%) were primary missions, whereas 129 (75.9%) were interhospital transports. Most patients (158 [92.9%]) were transported with ground-based vehicles, and 12 (7.1%) were transported by rotor wing aircrafts. One hundred thirty-four of 170 patients (78.8%) were COVID-19 positive at the time of transportation. The median (interquartile range) fraction of inspired oxygen concentration was 0.60 (0.50-0.80), the positive end-expiratory pressure was 11 cm HO (8-13.5 cm HO), and the peak inspiratory pressure was 26 cm HO (22-30 cm HO). Some degree of elevated treatment challenge was reported in 157 (87.7%) transports, and in 139 (77.7%), the patient risk was considered elevated. The physician stated that some degree of elevated risk for the provider was elevated in 131 (73.2%) of the transports.
The capacity of the physician-manned emergency medical services to safely transfer patients remains essential to maintain resilient critical care capacity, and the perceived elevated risks should be considered in capacity planning.
挪威的重症监护资源实行区域化管理，这使得空运救护车转运疑似或确诊 2019 冠状病毒病（COVID-19）阳性患者成为必要。我们前瞻性地观察了我们的医生配备的紧急医疗服务对疑似或确诊 COVID-19 患者的院前和院内转运。
这是一项针对 COVID-19 大流行期间由 2 架挪威空中救护车执行的初级和二级任务的前瞻性、观察性质量保证研究。
41 例（24.1%）为初级任务，129 例（75.9%）为院内转运。大多数患者（158 例[92.9%]）通过地面车辆转运，12 例（7.1%）通过旋翼飞机转运。在转运时，170 例患者中有 134 例（78.8%）COVID-19 阳性。吸入氧浓度中位数（四分位距）为 0.60（0.50-0.80），呼气末正压为 11 厘米水柱（8-13.5 厘米水柱），吸气峰压为 26 厘米水柱（22-30 厘米水柱）。在 157 次转运中（87.7%）报告了某种程度的治疗挑战增加，在 139 次转运中（77.7%），患者风险被认为增加。医生表示，在 131 次转运中（73.2%），提供者的风险在某种程度上增加。
医生配备的紧急医疗服务有能力安全转运患者，这对于维持有弹性的重症监护能力仍然至关重要，应在能力规划中考虑到感知到的风险增加。
