Acoustic Reflection Method and Work of Breathing

NCT00950443 · Status: TERMINATED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 38

No results posted yet for this study

Summary

Upper airway obstruction (UAO) is very common in children. Presently, the importance of the UAO is evaluated by the physician during an endoscopic evaluation under general anaesthesia.

The aim of the study is to evaluate two new techniques to quantify the importance of the UAO in children; the acoustic reflection method and the measurement of the work of breathing.

80 children will be included in this monocentric, prospective, open labelled study.

Conditions

  • Airway Obstruction

Interventions

DEVICE

Acoustic reflection method

Acoustic reflection gives the longitudinal cross-sectional area profile along airway.Based on planar acoustic wave propagating in a rigid duct connected to airway.

DEVICE

Acoustic method and breathing/endoscopic evaluation

Endoscopic evaluation done under general anaesthesia.
