Brief Summary:
The goal of this study is to learn more about voice and airway problems that patients experience during and after the time patients have an oral endotracheal tube in patients' airway to help patients breathe while receiving mechanical ventilation in an intensive care unit (ICU).

Study Type : Observational
Estimated Enrollment : 330 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Post-extubation Assessment of Laryngeal Symptoms and Severity
Actual Study Start Date : February 12, 2019
Estimated Primary Completion Date : December 2022
Estimated Study Completion Date : December 2022

Intervention Details:
  • Diagnostic Test: laryngoscopy
    A flexible camera (fiberoptic endoscope) is placed in the patient's nose to view the nose, throat, and airway.


Primary Outcome Measures :
  1. Laryngeal injury as assessed by 4-point categorical scale [ Time Frame: Within 72 hours post-extubation ]
    Characterize injuries to the larynx and surrounding tissues/anatomy after mechanical ventilation is no longer required and the oral endotracheal tube is removed. Injuries will be graded on a 4-point categorical scale ranging from 0 (no injury) to 3 (severe injury).

  2. Laryngeal injury symptom grading by Laryngeal Hypersensitivity Questionnaire (LHQ) [ Time Frame: Within 48 hours of anticipated extubation ]
    Characterize patient symptoms of laryngeal injury within 48 hours of anticipated extubation. Symptoms will be assessed using a 4-point ordinal scale based on the LHQ, ranging from 1 (all of the time) to 4 (none of the time).

  3. Laryngeal injury symptom grading by LHQ [ Time Frame: Within 72 hours post-extubation ]
    Characterize patient symptoms of laryngeal injury within 72 hours post-extubation. Symptoms will be assessed using a 4-point ordinal scale based on the LHQ, ranging from 1 (all of the time) to 4 (none of the time).

  4. Laryngeal injury symptom grading by LHQ [ Time Frame: 7 days post-extubation or hospital discharge, whichever occurs first ]
    Characterize patient symptoms of laryngeal injury at 7 days post-extubation or at discharge whichever comes first. Symptoms will be assessed using a 4-point ordinal scale based on the LHQ, ranging from 1 (all of the time) to 4 (none of the time).


Secondary Outcome Measures :
  1. Oral endotracheal tube size [ Time Frame: At the time of intubation (directly following study enrollment) ]
    Size of the endotracheal tube

  2. Duration of orotracheal intubation [ Time Frame: From date of intubation to date of extubation or when trached, whichever comes first, assessed up to 14 days ]
    Number of days from placement to extubation of the oral endotracheal tube

  3. Perceptual voice characteristics as assessed by Grade Rough Breathy Asthenic Strained (GRBAS) method [ Time Frame: Within 72 hours post-extubation ]
    Assessed from standardized voice samples and digital recordings using the grade, rough, breathy, asthenic, and strained (GRBAS) method with a 4-point ordinal scale ranging from 0 (normal) to 3 (severe).

  4. Perceptual voice characteristics as assessed by GRBAS method [ Time Frame: 7 days post-extubation or hospital discharge, whichever occurs first ]
    Assessed from standardized voice samples and digital recordings using the grade, rough, breathy, asthenic, and strained (GRBAS) method with a 4-point ordinal scale ranging from 0 (normal) to 3 (severe).

  5. Perceptual voice characteristics as assessed by Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) [ Time Frame: Within 72 hours post-extubation ]
    Assessed from standardized voice samples and digital recordings using the CAPE-V, which is comprised of a 100-point visual analog scale ranging from 0 (normal) to 100 (severe)

  6. Perceptual voice characteristics as assessed by CAPE-V [ Time Frame: 7 days post-extubation or hospital discharge, whichever occurs first ]
    Assessed from standardized voice samples and digital recordings using the CAPE-V, which is comprised of a 100-point visual analog scale ranging from 0 (normal) to 100 (severe)

  7. Acoustic voice measurement as assessed by voice analysis software [ Time Frame: Within 72 hours post-extubation ]
    Assessed from standardized voice samples and digital recordings using the Computerized Speech Lab (PENTAX Medical) with voice analysis software (viz., Multi-Dimensional Voice Program (MDVP); Analysis of Dysphonia in Speech and Voice (ADSV)) to quantify voice characteristics across a number of parameters

  8. Acoustic voice measurement as assessed by voice analysis software [ Time Frame: 7 days post-extubation or hospital discharge, whichever occurs first ]
    Assessed from standardized voice samples and digital recordings using the Computerized Speech Lab (PENTAX Medical) with voice analysis software (viz., Multi-Dimensional Voice Program (MDVP); Analysis of Dysphonia in Speech and Voice (ADSV)) to quantify voice characteristics across a number of parameters.
