To the Editor,We read with great interest the September Special Issue on Airway Management of the Journal and noted the timely consideration of aerosol precautions in many articles.[1] Our hospital policy recommends videolaryngoscopy (VL) for maximal provider safety because of infectious disease concerns such as COVID 19,[2] but VL is considered relatively contraindicated in the setting of a profusely bleeding airway because of potential camera contamination.[3] Thus, optimal care may conflict with optimal provider protective strategies.[1]Despite limited clinical evidence, the Ducanto “suction-assisted laryngoscopy airway decontamination (SALAD)” direct laryngoscopy (DL) approach has been accepted as a method to manage the soiled airway[4,5] (Figure).The suction-assisted laryngoscopy airway decontamination (SALAD) approach. Reproduced with permission from: Kovacs G, Sowers N. Airway Management in Trauma. Emerg Med Clin North Am 2018; https://doi.org/10.1016/j.emc.2017.08.006Two studies have examined the effectiveness of VL vs DL in the soiled airway in the clinical setting.[6,7] In a retrospective review of 4,626 intubations in an academic emergency department, Sackles et al. observed no difference in first-attempt success rate between the GlideScope® (Verathon Inc., Bothell, WA, USA) and DL in patients with a soiled airway.[7] Similarly, Carlson et al.[6] found similar success rates between VL and DL in their retrospective analysis of 325 intubations in patients with large volume hematemesis secondary to gastrointestinal bleeds.At London Health Sciences Center, this provider/care conflict was recently illustrated in a young COVID-19-suspect patient bleeding profusely from esophageal varices. The patient was anemic and hemodynamically unstable, prompting emergent intubation by the protected airway management team to facilitate Blakemore tube insertion.Considering the conflict, the decision was made to prioritize provider safety and proceed with videolaryngoscopy. To minimize the potential for soiling of the videolaryngoscope camera, it was planned to have two suction apparatuses manned by adjacent respiratory therapists (RT) while the anesthesiologist secured the airway via VL. The backup plan was to insert a larger endotracheal tube (ETT) into the esophagus to provide an outlet for the blood, and intubate around this suctioned “esophageal vent.”Two suction apparatuses and an additional backup suction were available. A McGRATH™ laryngoscope (Medtronic, Minneapolis, MN, USA) with several size 3 and 4 blades was available to backup the primary GlideScope (Verathon
Inc, Bothell, WA, USA) size 3 (hyperangulated) laryngoscope. After paralysis, one suction catheter was introduced along with the GlideScope to “protect the camera.” This suction was then passed off to an RT. A second suction catheter was then inserted and delegated to the other RT. Although the videolaryngoscope required maneuvering to avoid the blood welling up from the esophagus, it appeared that its screen enabled the RTs to suction more effectively than when assisting DL because they could better optimize their position, facilitating a successful intubation.Overall, we were impressed with how effective videolaryngoscopy-guided suctioning was compared with blind suctioning after suction was delegated by the intubator to grasp the ETT. There may be less of a conflict than perceived; we strongly recommend this technique be considered for intubating a soiled airway when infectious precautions are required. Furthermore, we suggest that it may be worth considering this technique even if aerosol precautions are not required, if any other predictors for difficult laryngoscopy[1] are present in combination with a soiled airway.
