ABSTRACT
BACKGROUND: The epidemiology, morbidity, and burden of the disease related to airway sequelae associated with invasive mechanical ventilation (IMV) in the context of the COVID-19 pandemic remain unclear. OBJECTIVE: This scoping review aims to summarize the current knowledge regarding airway sequelae after severe SARS-CoV2 infection. This knowledge will help guide research endeavors and decision-making in clinical practice. METHODS: This scoping review will include participants of all genders and no particular age group who developed post-COVID airway related complication will be excluded. No exclusion criteria will be applied from country, language or document type. The information source will include analytical observational, observational studies. Unpublished data will not be completely covered as grey literature will be covered. A total of 2 independent reviewers will participate in the process of screening, selection, and data extraction, and the whole process will be performed blindly. Conflict between reviewers will be solve through discussion and additional reviewer. Results will be reported by using descriptive statistics and information will be displayed on RedCap. RESULTS: The literature search was conducted in May 2022 in in the following databases; PubMed, EMBASE, SCOPUS, Cochrane Library, LILACS and Grey literature to identify observational studies; a total of 738 results were retrieved. The scoping review will be finished by March-2023. CONCLUSIONS: This scoping review will describe current knowledge on the most frequently encountered laryngeal and/or tracheal sequelae in patients exposed to mechanical ventilation due to SARS-CoV-2 infection. This scoping review will find the incidence of airway sequelae post-COVID19 and the most common sequelae such as; airway granuloma, vocal fold paralysis, and airway stenoses. Future studies should evaluate the incidence of these disorders. INTERNATIONAL REGISTERED REPORT: PRR1-10.2196/41811.
ABSTRACT
Coronavirus disease 2019 (COVID-19) has increased the risk of developing severe acute respiratory distress syndrome and subsequent moderate to severe laryngotracheal stenoses (LSTs) with an early presentation that occurs between two and three months after SARS-CoV-2 infection. We present a series of 12 cases of LST following SARS-CoV-2 infection. Dense lymphocyte infiltration with multinuclear giant cell granulomas was found on biopsy with intranuclear inclusions, suggestive of viral cytopathic effects in one case and intravascular fibrin thrombi with perivascular mononuclear infiltrate of CD3 + T lymphocytes. We present the largest and only series that describes clinical and histopathological characteristics of LTS and the management and outcomes after early laryngotracheal reconstruction in the context of the SARS-CoV-2 outbreak.
