About this trial

This is an interventional treatment trial for Tracheal Stenosis focused on measuring tracheal stenosis, tracheal dilatation, ventilation

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Age >18 years
  • Symptoms of tracheal or laryngeal stenosis or airway narrowing
  • Endoscopic evidence of subglottic or tracheal stenosis
  • Able to provide informed consent

Exclusion Criteria:

  • Refractory stenosis not amenable to balloon dilatation
  • Contraindication to balloon dilatation
  • Lack of informed consent

Sites / Locations

  • Groote Schuur Hospital

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Dilatation

Arm Description

Patients undergoing tracheal dilatation with the study device

Outcomes

Primary Outcome Measures

Incidence of peripheral arterial desaturation
Incidence of desaturation below 90% as measured by peripheral pulse oximeter
Time to desaturation
Time to desaturation below 90% as measured by peripheral pulse oximeter

Secondary Outcome Measures

Efficacy of tracheal dilatation by comparison of pre- and post-dilatation Myer-Cotton grading
Describes the stenosis based on the percent relative reduction in cross-sectional area of the subglottis. Four grades of stenosis: grade I lesions have less than 50% obstruction, grade II lesions have 51% to 70% obstruction, grade III lesions have 71% to 99% obstruction, grade IV lesions have no detectable lumen or complete stenosis.
Incidence of major adverse events

5. Study Description

Brief Summary
The purpose of the study is to prospectively assess the use of a modified tracheal balloon dilator that allows gas flow (oxygenation and ventilation) through the device while inflated during dilatation.
Detailed Description
The primary aim is to determine the incidence of, and time to, arterial desaturation (defined as peripheral plethysmography below 90%). Secondary aims include quantitative and qualitative (waveform) end-tidal capnography levels throughout the procedure, quantitative assessment of dilatation, and incidence of adverse events.
