Tracheostomy was performed for patients with carcinoma of tonsil (n=2)
and nasopharynx (n=1), and aspiration pneumonia (n=2). Droplet
contamination was noted on all plastic sheets (n=5). Droplet
contamination was most severe over the central surface at 91.5%
(86.7%-100.0%) followed by the left and right lateral surfaces at
5.2% (6.7%-10.0%) and 3.3% (6.7%-10.0%) respectively. No droplet
contamination was noted on all face shields.
