Effect of an Aerosol Box on Intubation in Simulated Emergency Department Airways: A Randomized Crossover Study
Introduction: The use of transparent plastic aerosol boxes as protective barriers during
endotracheal intubation has been advocated during the severe acute respiratory syndrome
coronavirus 2 pandemic. There is evidence of worldwide distribution of such devices, but some
experts have warned of possible negative impacts of their use. The objective of this study was to
measure the effect of an aerosol box on intubation performance across a variety of simulated difficult
airway scenarios in the emergency department.
Methods: This was a randomized, crossover design study. Participants were randomized to
intubate one of five airway scenarios with and without an aerosol box in place, with randomization
of intubation sequence. The primary outcome was time to intubation. Secondary outcomes included
number of intubation attempts, Cormack-Lehane view, percent of glottic opening, and resident
physician perception of intubation difficulty.
Results: Forty-eight residents performed 96 intubations. Time to intubation was significantly
longer with box use than without (mean 17 seconds [range 6-68 seconds] vs mean 10 seconds
[range 5-40 seconds], p <0.001). Participants perceived intubation as being significantly more
difficult with the aerosol box. There were no significant differences in the number of attempts or
quality of view obtained.
Conclusion: Use of an aerosol box during difficult endotracheal intubation increases the time to
intubation and perceived difficulty across a range of simulated ED patients
Evidence of the Importance of Host Habitat Use in Predicting the Dilution Effect of Wild Boar for Deer Exposure to Anaplasma spp
Foci of tick-borne pathogens occur at fine spatial scales, and depend upon a complex arrangement of factors involving climate, host abundance and landscape composition. It has been proposed that the presence of hosts that support tick feeding but not pathogen multiplication may dilute the transmission of the pathogen. However, models need to consider the spatial component to adequately explain how hosts, ticks and pathogens are distributed into the landscape
