Characteristics of Hybrid Modified Percutaneous Dilatational Tracheostomy in Patients With COVID-19: A Single Institutional Experience Over 1 Year / 대한이비인후과학회지

ABSTRACT

Background and Objectives@#Coronavirus disease 2019 (COVID-19) is a worldwide pandemic, and some patients require mechanical ventilation and tracheostomy. Owing to the risks of aerosol spreading to health care workers, the protocols and guidelines related to the novel timing and technique for tracheostomy are rapidly changing. We investigated the characteristics of tracheostomy with patients with COVID-19 over a year.Subjects and Method We measured the mean time from intubation to the tracheostomy, survival rate, the incidence of infection to medical staff, and operation time, complications for tracheostomy, and the time of decannulation. All patients underwent a novel percutaneous tracheostomy without bronchoscope (hybrid modified percutaneous dilatational tracheostomy, hybrid MPDT) in the negative pressure intensive care unit. @*Results@#Of the 448 patients with COVID-19 patients, 34 required invasive mechanical ventilation at a tertiary hospital from February 2020 to April 2021. Of those, 15 patients underwent tracheostomy. Of the tracheostomy patients, survival rate was 93.33%. The mean time from intubation to the tracheostomy was 18.27±14.74 days (range, 8-36 days). The incidence of infection to medical staff was zero percent whereas racheostomy-related bleeding was the most common complication (2 patients). Operation time for hybrid MPDT was 5.45±1.12 min. @*Conclusion@#The optimal timing of tracheostomy procedure for COVID-19 patients is still unknown, but it is believed that the treatment of COVID-19 can be achieved better if the hybrid MPDT is used at the right time.
