Abstract
INTRODUCTION At the beginning of the coronavirus disease 2019 (COVID‐19) pandemic caused by severe respiratory syndrome coronavirus 2 (SARS‐CoV‐2), approximately 5% of patients with COVID‐19 were classed as critical, requiring [...]
: Objectives: Laryngeal complications have been reported after endotracheal intubation and prone positioning in patients with critical coronavirus disease 2019 (COVID‐19), but their association is unclear. In this study, we investigated the rate of laryngeal complications in patients with COVID‐19 compared to an alternative condition (control group). Methods: We retrospectively analyzed the data of 40 patients who underwent endotracheal intubation for either COVID‐19 or an alternative condition (control group). Data on age, sex, body mass index (BMI), cardiovascular disease (CVD) risk factors, use of prone therapy, duration of endotracheal intubation, and duration from extubation/tracheostomy to laryngeal evaluation were collected from medical records. Results: There were no significant differences in BMI, frequency of CVD risk factors, duration of endotracheal intubation, or duration from extubation/tracheostomy to laryngeal evaluation between the two groups. In the COVID‐19 group, all patients adopted the prone position. In comparison, only one patient in the control group adopted the prone position. Significant differences were observed between the two groups regarding the incidence of vocal fold immobility and laryngeal granuloma. Conclusion: Laryngeal complications were more common in the COVID‐19 group than in the control group. Prone positioning may be a risk factor for these complications. Level of Evidence: 4.
