Modified Negative Pressure Enclosure During Tracheostomy in Patients With COVID-19

COVID-19 also known as severe acute respiratory syndrome coronavirus 2 is the result of a highly transmissible coronavirus which can result in severe infection of the respiratory tract. The global pandemic which began in early 2020 has created a number of challenges for the medical community to contain the rate of transmission, especially to health care workers. A minority of the infected population will progress toward severe respiratory distress ultimately requiring mechanical ventilator assistance. Although preliminary data suggest a poor prognosis for those requiring ventilation support, there is a subgroup who will eventually be weaned off. As the pandemic evolves, this cohort of infected, chronically intubated and ventilated individuals will become more prevalent and may require tracheostomy to aid in recovery. Unfortunately, tracheostomy is an aerosol-generating procedure which poses high risks to all members within the operating room, as described by previous authors. There is an urgent need to explore and develop methods to maximize the safety of tracheostomy and other aerosol-generating procedures in order to reduce intraoperative transmission. In the present article, we present a modified technique for negative pressure enclosure in patients with COVID-19 who underwent tracheostomy.
