COVID-19: Intensive care management.

The SARS-coronavirus 2 disease initially reported in December 2019 in China (COVID-19) represents a major challenge for intensive care medicine, due to the high number of ICU admission and the prolonged stay for many patients. Up to 5% of COVID-19 infected patients develop severe acute hypoxemic respiratory failure requiring invasive mechanical ventilation as supportive treatment. Apart from early antiviral and anti-inflammatory treatment, the management of COVID-19 patients is mainly applying protective mechanical ventilation, to support the injured lungs. However recently acquired data and clinical experience suggest that COVID-19-related ARDS presents some specificities that will be summarized in the present article.Copyright © 2020 Editions Medecine et Hygiene.

[Covid-19 respiratory sequelae : Screening and management]

Infection with SARS-CoV-2 can affect multiple organ systems with variable severity and is known to frequently have a major impact on the respiratory system. Symptoms may persist for several months after infection, and are associated with a reduction of lung function, diminished exercise capacity and anomalies on chest CT. Guidelines on the post-acute care of patients with SARS-CoV-2 are now available. Pulmonary rehabilitation plays a central role in the recovery of exercise capacity, notably in severe cases. The role of specific therapies, such as corticosteroids, anti-fibrotics and lung transplantation remains uncertain and needs to be evaluated on a case-by-case basis.

Transforming operating rooms into an intensive care unit to manage the COVID-19 outbreak

This article is a descriptive analysis of the organizational steps undertaken to transform eight OR (operating rooms) of the University Hospital Lausanne CHUV into a dedicated ICU (intensive care unit) during the COVID-19 pandemic. An efficient response of our institution was mandatory to timely increase the number of ICU beds. The transformation of an entire floor of a functioning operating ward was deemed the most appropriate solution to provide rapidly a significant number of beds. The newly created ICU was the first additional ICU to open and admitted its first patient 48 hours after the beginning of the transformation.

Pulmonary function and radiological features 4 months after COVID-19: first results from the national prospective observational Swiss COVID-19 lung study

BACKGROUND: The infectious coronavirus disease 2019 (COVID-19) pandemic is an ongoing global healthcare challenge. Up to one-third of hospitalised patients develop severe pulmonary complications and acute respiratory distress syndrome. Pulmonary outcomes following COVID-19 are unknown. METHODS: The Swiss COVID-19 lung study is a multicentre prospective cohort investigating pulmonary sequelae of COVID-19. We report on initial follow-up 4 months after mild/moderate or severe/critical COVID-19 according to the World Health Organization severity classification. RESULTS: 113 COVID-19 survivors were included (mild/moderate n=47, severe/critical n=66). We confirmed several comorbidities as risk factors for severe/critical disease. Severe/critical disease was associated with impaired pulmonary function, i.e. diffusing capacity of the lung for carbon monoxide (D _LCO) % predicted, reduced 6-min walk distance (6MWD) and exercise-induced oxygen desaturation. After adjustment for potential confounding by age, sex and body mass index (BMI), patients after severe/critical COVID-19 had a D _LCO 20.9% pred (95% CI 12.4-29.4% pred, p=0.01) lower at follow-up. D _LCO % pred was the strongest independent factor associated with previous severe/critical disease when age, sex, BMI, 6MWD and minimal peripheral oxygen saturation at exercise were included in the multivariable model (adjusted odds ratio per 10% predicted 0.59, 95% CI 0. 37-0.87;p=0.01). Mosaic hypoattenuation on chest computed tomography at follow-up was significantly associated with previous severe/critical COVID-19 including adjustment for age and sex (adjusted OR 11.7, 95% CI 1.7-239;p=0.03). CONCLUSIONS: 4 months after severe acute respiratory syndrome coronavirus 2 infection, severe/critical COVID-19 was associated with significant functional and radiological abnormalities, potentially due to small-airway and lung parenchymal disease. A systematic follow-up for survivors needs to be evaluated to optimise care for patients recovering from COVID-19.
