Ultrasonography in Confirming Proper Position of Endotracheal Tube

Ultrasonography in Confirming Proper Position of Endotracheal Tube in Emergency Department at Siriraj Hospital: Applicability and Accuracy

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.

Study Overview

• Status: Completed
• Conditions: Endotracheal Tube Wrongly Placed During Anesthetic Procedure
• Intervention / Treatment: Device: Ultrasonography (Sonosite )

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The confirmation of ETT depth	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.	1 hour

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The confirming the presence of ETT in airway.	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.	1 hour
