RESUMO
BACKGROUND: Coronavirus disease (COVID-19) primarily affects the lungs and lower airways and may present as hypoxaemic respiratory failure requiring admission to an intensive care unit (ICU) for supportive treatment. Here, supplemental oxygen remains essential for COVID-19 patient management, but the optimal dosage is not defined. We hypothesize that targeting an arterial partial pressure of oxygen of 8 kPa throughout ICU admission is superior to targeting 12 kPa. METHODS: The Handling Oxygenation Targets in ICU patients with COVID-19 (HOT-COVID) trial, is an investigator-initiated, pragmatic, multicentre, randomized, parallel-group trial comparing a lower oxygenation target versus a higher oxygenation target in adult ICU patients with COVID-19. The primary outcome is days alive without life-support (use of mechanical ventilation, renal replacement therapy or vasoactive therapy) at day 90. Secondary outcomes are 90-day and 1-year mortality, serious adverse events in the ICU and days alive and out of hospital in the 90-day period, health-related quality-of-life at 1 year, and health economic analyses. One-year follow-up of cognitive and pulmonary function is planned in a subgroup of Danish patients. We will include 780 patients to detect or reject an absolute increase in days alive without life-support of 7 days with an α of 5% and a ß of 20%. An interim analysis is planned after 90-day follow-up of 390 patients. CONCLUSIONS: The HOT-COVID trial will provide patient-important data on the effect of two oxygenation targets in ICU patients with COVID-19 and hypoxia. This protocol paper describes the background, design and statistical analysis plan for the trial.

We present two cases in which elderly male recreational cyclists suffered from cervical fractures and coinciding injuries of the spinal cord that subsequently led to cardiac arrest.Based on reports from eye witnesses and due to the low impact nature of the crashes, the two patients were initially considered as having cardiac arrest before falling of their bikes.The spinal cord injuries triggering cardiac arrest were acknowledged with delay, as the primary eliciting cause was considered cardiac disease in conjunction with all-out exercise. We suggest that increased focus should be made on possible cervical injuries even following low energy crashes in road cycling.
