  Purpose

The purpose of this study is to assess the applicability of using ultrasonography in confirmation of the position of the endotracheal tube (ETT) after intubated to patients.


Condition Intervention
Endotracheal Tube Wrongly Placed During Anesthetic Procedure
 Device: Ultrasonography (Sonosite )

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective
Official Title: Ultrasonography in Confirming Proper Position of Endotracheal Tube in Emergency Department at Siriraj Hospital: Applicability and Accuracy

Further study details as provided by Mahidol University:

Primary Outcome Measures:
  • The confirmation of ETT depth [ Time Frame: 1 hour ] [ Designated as safety issue: Yes ]
    A transcricothyroid membrane view of the ultrasonography was chosen for confirmation of ETT depth measurement. Firstly, measured the distance from probe (skin) to anterior surface of ETT. Then, measured the distance from probe (skin) to balloon cuff level. Finally the depth of ETT (Distance from vocal cord to balloon cuff) was calculated by using Pythagorus rule.


Secondary Outcome Measures:
  • The confirming the presence of ETT in airway. [ Time Frame: 1 hour ] [ Designated as safety issue: Yes ]
    A transcricothyroid membrane view was chosen for confirmation of ETT position. Various glottic structures such as True Vocal Cord (TVC), False Vocal Cord (FVC), and arythenoid cartilage can be visualized.


Enrollment: 80

Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Intubate Device: Ultrasonography (Sonosite )
Sonosite MICROMAXXTM with linear probe L38e/10-5 MHz

Detailed Description:

To assess the applicability of using ultrasonography as compared to routine portable CXR in confirmation of ETT position.

To determine the accuracy of ultrasonography in measuring the depth of ETT as compare to standard CXR method.
