Utilization of an Orthopedic Hood as Personal Protective Equipment for Intubation of Coronavirus Patients: a Brief Technical Report

BACKGROUND: The novel coronavirus disease (COVID-19) has afflicted millions of people worldwide since its first case was reported in December 2019. Personal protective equipment (PPE) has been tailored accordingly, but as of April 2020, close to 10 000 health care workers in the United States have contracted COVID-19 despite wearing recommended PPE. As such, standard guidelines for PPE may be inadequate for the health care worker performing high-risk aerosolizing procedures such as endotracheal intubation. In this brief technical report, we describe the integration of an orthopedic hood cover as an item for full barrier protection against COVID-19 transmission. TECHNICAL DESCRIPTION: The Coronavirus Airway Task Force at Virginia Commonwealth University Medical Center approved this initiative and went live with the full barrier suit during the last week of March 2020. The PPE described in this report includes a Stryker T4 Hood, normally used in conjunction with the Stryker Steri-Shield T4 Helmet. Instead of the helmet, the hood is secured to the head via a baseball cap and binder clip. This head covering apparatus is to be used as an accessory to other PPE items that include an N95 mask, waterproof gown, and disposable gloves. The motor ventilation system is not used in order to prevent airborne viral entry into the hood. DISCUSSION: An advantage of the full barrier suit is an additional layer of droplet protection during intubation. The most notable disadvantage is the absence of a ventilation system within the hood covering. CONCLUSION: Modification of existing PPE may provide protection for health care workers during high-risk aerosolizing procedures such as endotracheal intubation. Although the integration of this medical equipment meets the immediate needs of an escalating crisis, further innovation is on the horizon. More research is needed to confirm the safety of modified PPE.
