Table 1. Median intubation times with and without the aerosol box, grouped by training level.

All intubation attempts were completed on the first attempt without any complications. Trainees consisted of eight anesthesia residents and one anesthesia fellow. Statistically significant difference in intubation times between attempts with the aerosol box versus without the aerosol box (p < 0.001, z-score = -7.831). Pearson’s coefficient (r = -0.554) is indicative of a medium effect size. Differences between attendings, trainees, and certified registered nurse anesthetists (CRNA) were not found to be statistically significant for both median intubation times without the box (p = 0.832) and median intubation times with the box (p = 0.060)
