Early tracheostomy is recommended for patients that are expected to be on prolonged mechanical ventilation; however, supporting data has not yet been provided for early tracheostomies in COVID-19 patients. The aim of this study was to explore established guidelines for performing tracheostomies in patients diagnosed with COVID-19. Factors considered were patient outcomes such as mortality, ventilator-associated pneumonia, intensive care unit length of stay, complications associated with procedures, and risks to healthcare providers that performed tracheostomies. Various observational studies, meta-analyses, and systematic reviews were collected through a PubMed Database search. Additional sources were found through Google. The search was refined to publications in English and between the years of 2003 and 2021.

ECMO therapy requires sedation of the patient, which is usually achieved by intravenous administration of sedatives. The shortage of intravenous sedative drugs due to the ongoing pandemic, and attempts to improve treatment outcome for COVID-19 patients, drove the application of inhaled sedation as a promising alternative for sedation during ECMO therapy.
