Development of an institutional protocol for percutaneous dilatational tracheostomy in critically ill COVID-19 patients: Initial experience.
Background and Aims: Percutaneous dilatational tracheostomy (PDT) may improve the outcome in critically ill COVID-19 patients on mechanical ventilation. However, the timing of performing tracheostomy may be controversial, and it is an aerosol-generating procedure with a potential risk of viral exposure to healthcare workers.
Material and Methods: An operational protocol for performing PDT was made and subsequently followed in a designated COVID-19 ICU. Critically ill adult patients on mechanical ventilators who underwent PDT were included in this retrospective cohort study. Case files were retrospectively reviewed and patient characteristics, clinical outcome, and procedure-related details were noted.
Results: Forty-one patients were included in the analysis. The median age was 49 (39-67) years, and 41.5% of patients were females. The median duration of mechanical ventilation before tracheostomy was 10 (8-16) days, and the median (IQR) PaO2 /FiO2 ratio on the day of PDT was 155 (125-180) mm Hg. Further, 48.8% of patients had transient desaturation to SpO2 <90%, and 41.5% survived to ICU discharge. None of the health care providers involved in PDT developed any symptoms of COVID 19.
Conclusion: This descriptive study demonstrates the feasibility, implementation, and apparent safety of the PDT protocol developed at our institution.
