Purpose To describe the sequelae of oral endotracheal intubation by evaluating prevalence rates of structural injury, hyposalivation, and impaired vocal production over 14days following extubation.Materials and methods Consecutive adults (≥20years, N=114) with prolonged (≥48h) endotracheal intubation were enrolled from medical intensive care units at a university hospital. Participants were assessed by trained nurses at 2, 7, and 14days after extubation, using a standardized bedside screening protocol.Results Within 48-hour postextubation, structural injuries were common, with 51% having restricted mouth opening. Unstimulated salivary flow was reduced in 43%. For vocal production, 51% had inadequate breathing support for phonation, dysphonia was common (94% had hoarseness and 36% showed reduced efficiency of vocal fold closure), and >40% had impaired articulatory precision. By 14days postextubation, recovery was noted in most conditions, but reduced efficiency of vocal fold closure persisted. Restricted mouth opening (39%) and reduced salivary flow (34%) remained highly prevalent.Conclusions After extubation, restricted mouth opening, reduced salivary flow, and dysphonia were common and prolonged in recovery. Reduced efficiency of vocal cord closure persisted at 14days postextubation. The extent and duration of these sequelae remind clinicians to screen for them up to 2weeks after extubation.
