Mesostructural characterization of ETT-deposited BF. (A) Macroscopic view of ETT section before confocal microscopy ; (B) confocal image of an ETT section showing ribbon-shaped BF deposited on the inner surface (scale bar, 75 µm) ; (C) confocal image of an ETT section showing mushroom-shaped BF deposited on the inner surface (scale bar, 75 µm) ; (D) zoomed confocal image of an ETT section showing ribbon-shaped BF deposited on the inner surface (scale bar, 25 µm) ; (E) zoomed confocal image of an ETT section showing mushroom-shaped BF deposited on the inner surface (scale bar, 25 µm) ; (F) correlation curve between the length of MV duration and BF thickness ; (G) comparison of median MV duration between ribbon- and mushroom-shaped BF ; H. comparison of median BF thickness between ribbon- and mushroom-shaped BF. BF biofilm, ETT endotracheal tube, MV mechanical ventilation, ns not significant.
