Post-extubation Assessment of Laryngeal Symptoms and Severity

Completed
Conditions
Intubation, Intratracheal
Complication of Ventilation Therapy
Critical Illness
Mechanical Ventilation Complication
Registration Number
NCT03726086
Lead Sponsor
Johns Hopkins University
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).

Primary Outcome Measures
NameTimeMethod
Laryngeal injury as assessed by 4-point categorical scaleWithin 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).

Laryngeal injury symptom grading by Laryngeal Hypersensitivity Questionnaire (LHQ)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).

Laryngeal injury symptom grading by LHQ7 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
NameTimeMethod
Perceptual voice characteristics as assessed by Grade Rough Breathy Asthenic Strained (GRBAS) methodWithin 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).

Perceptual voice characteristics as assessed by GRBAS method7 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).

Isometric Hand Grip Strength-DynamometryWithin 48 hours of anticipated extubation, within 72 hours post-extubation, and at 7 days post-extubation or hospital discharge, whichever occurs first

Grip strength provides a measure of distal muscle strength that has important functional application for patients. Grip strength, tested by hand grip dynamometry, will be assessed in each hand using a Jamar Preston hand dynamometer

Yale Swallow ProtocolWithin 72 hours post-extubation

A cognitive screen and administration of a cup containing 3 oz. (90 ml) of water handed to the patient for uninterrupted continuous consumption via cup or straw. Interrupted consumption (i.e., stopping, resting), and/or coughing, choking, throat clearing, or a change in vocal quality (i.e., a wet, gurgly quality after consumption is completed) signifies a failed screening.

Oral endotracheal tube sizeAt the time of intubation (directly following study enrollment)

Size of the endotracheal tube

Duration of orotracheal intubationFrom date of intubation to date of extubation or placement of a tracheostomy tube, whichever occurs first, assessed up to 14 days

Number of days from placement to extubation of the oral endotracheal tube

Patient perception of voice and voice symptoms assessed by the Voice Symptom Scale (VoiSS)Within 72 hours post-extubation and at 7 days post-extubation or hospital discharge, whichever occurs first

a 30-item questionnaire that uses scaled scores across 3 domains-impairment (15 items), physical symptoms (8 items), and emotional response (7 items).

Function Oral Intake Scale (FOIS)Within 90 days of extubation or at ICU discharge, whichever occurs first

A 7-point clinical scale to document change in functional oral intake of food and liquid in patients.

Acoustic voice measurement as assessed by voice analysis software7 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.

Peak tongue strength assessed using the Iowa Oral Performance Instrument (IOPI)Within 48 hours of anticipated extubation, within 72 hours post-extubation, and at 7 days post-extubation or hospital discharge, whichever occurs first

Tongue strength, tested using tongue bulb pressure, will be assessed using the Iowa Oral Performance Instrument (IOPI)
