Ultrasonography in Confirming Proper Position of Endotracheal Tube

Completed

• Conditions: Endotracheal Tube Wrongly Placed During Anesthetic Procedure
• Interventions: Device: Ultrasonography (Sonosite )

• Registration Number: NCT01373437
• Lead Sponsor: Mahidol University

Brief Summary

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.

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.

Group	Intervention	Description
Intubate	Ultrasonography (Sonosite )	-

Primary Outcome Measures

Name	Time	Method
The confirmation of ETT depth	1 hour	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

Name	Time	Method
The confirming the presence of ETT in airway.	1 hour	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.
