ABSTRACT
INTRODUCTION: The development of sleep disorders, and specifically insomnia, has been linked to the exposure to different stressors. In this line, Coronavirus disease 2019 (COVID-19) outbreak caused by the new coronavirus SARS-CoV-2, has caused a huge impact on our environment, and has exposed healthcare workers to an unprecedented threat. In this study, we try to assess sleep quality and the development of sleep disorders in health personnel directly dedicated to the care of COVID-19 patients at the height of the pandemic, compared to the general population. MATERIALS AND METHODS: A cross-sectional, anonymized, self-reported questionnaire survey was carried out at the "12 de Octubre" Hospital, in Madrid, Spain, during the outbreak of COVID-19, from March 1st to April 30th 2020. We compared two groups, healthcare workers who have treated directly COVID-19 patients versus non-healthcare workers. The questionnaire included demographic data, sleep related aspects, Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI) and 17-items Hamilton Rating Scale (HRS). RESULTS: In total 170 participants completed the questionnaire successfully, 100 healthcare workers and 70 non-healthcare workers. Self-reported insomnia, nightmares, sleepwalking, sleep terrors and PSQI>6 were more frequent in the healthcare group (p < 0,05). Shift work was associated to greater risk when performing multiple logistic regression analysis. CONCLUSIONS: We observed that, during the outbreak of COVID-19, healthcare workers on the front line developed more sleep disturbances than non-healthcare professionals, and they had worse quality of sleep. Special attention should be paid to shift workers. Concrete protection and prevention measures for particularly exposed population should be considered in pandemic situations.

BACKGROUND: Noninvasive ventilation (NIV) titration may be difficult when dynamic airway obstruction episodes persist, even with high expiratory positive airway pressure (EPAP). We aimed to determine the usefulness of videolaryngoscopy during NIV for identifying mechanisms and sites of obstruction and for providing a guide for their resolution in difficult-to-titrate subjects. METHODS: When obstructions during NIV were present in the built-in software, EPAP was raised to 12 cm H2O. If obstructions persisted, a polygraphy during NIV was performed; if the events occurred with effort, a videolaryngoscopy with nasal and oronasal masks in awake subjects was performed. RESULTS: In a population of 208 subjects in whom NIV was initiated, 13 were identified as difficult to titrate with persistent obstructions during NIV despite an EPAP of 12 cm H2O. Videolaryngoscopy during NIV was able to identify the mechanism and the site of obstruction in all cases. The obstruction under oronasal mask ventilation was due to soft-palate (velum) collapse in 4 subjects, to epiglottic backward movement in 5 other subjects, and to tongue-base obstruction reducing the retroglossal space in 3 more. Videolaryngoscopy during NIV demonstrated improvement in 9 subjects (69%) upon changing to nasal mask and suggested a possible surgical approach in 2 (15%); in one of these 2 subjects, a successful uvulopalatopharyngoplasty was performed. CONCLUSIONS: The use of videolaryngoscopy during NIV in difficult-to-titrate patients may help to identify the sites and mechanisms of obstruction and in some cases may improve quality of ventilation.
