The role of videolaryngoscopy in airway management of COVID-19 patients

Dear Editor,
The world is facing the first pandemic of the 21st century caused by a new coronavirus (SARS-CoV-2). This outbreak will mark a before and after. Airway management will not remain outside the evolution of these events. Difficult airway is a clinical problem far from being resolved. Thus, it remains an important cause of death and irreversible brain damage. The core recommendation of the recent guidelines focuses on limiting the duration and number of attempts at tracheal intubation in order to achieve early atraumatic intubation [1], the philosophy on which the vortex approach is based [2]. Likewise, the availability of videolaryngoscopy in all circumstances and locations where the airway is treated is advocated since it allows better visualisation of the glottis, increases successful intubations on the first attempt, and reduces failed tracheal intubations and therefore trauma to the upper airway [3, 4]. Thus, different meta-analyses have objectified the advantages of video-laryngoscopy compared to direct laryngoscopy [5]. Multiple publications have recommended the universalisation of videolaryngoscopy [3]. However, costs and rooted classical clinical practice have hampered the routine use of these devices. The coronavirus outbreak arises in this context.
SARS-CoV-2 is a highly contagious virus. Tracheal intubation involves exposing healthcare personnel to a high viral load, which determines a more severe disease in those professionals who become infected [6]. Thus, it is the procedure with the highest risk of aerosol generation, followed by tracheostomy, non-invasive ventilation, and facial mask ventilation [7]. Therefore, the airway must be specifically treated, maximizing patient and operator safety [8]. Tracheal intubation should be performed at the opportune time without undue delay. This allows proper preparation and planning, using the recommended personal protective equipment [9]. Rapid sequence induction is advocated to avoid the generation of aerosols by facial mask ventilation and the use of effective and precise tracheal intubation techniques that avoid repeated attempts and, therefore, greater exposure. In general, it is pertinent to avoid all those procedures that cause generation of aerosols [8, 9]. Several recommendations have recently been published [9, 10]. All of them propose the videolaryngoscope as the device of first choice for performing all intubations, being an element universally included in the...
