Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Correct positioning of the endotracheal tube (ETT) is crucial to ensure safe ventilation. To date, no test that can verify this right after intubation at the bedside exists. Indirect tests have false negative and positive results leading to complications or at least difficulties in performing effective ventilation of patients.

Bedside ultrasound could fill this need. Although bedside ultrasound may not be possible or useful in routine intubations, it may prove useful in difficult or questionable cases, where current clinical exams/techniques may not offer a reliable indication of endotracheal tube depth.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Ultrasound is able to visualize some parts of the trachea and the ETT therein and although the actual structures of interest (ETT tip and carina) are difficult or impossible to visualize reliably (due to their air contents reflecting ultrasound beams) one can use surrogates:

The cuff of the ETT can be visualized as it is in- or deflated or it can be filled with an air-fluid(saline) mixture to delineate it inside the trachea.

For the same reason (air reflecting ultrasound beams) the carina is difficult to visualize and one can use the aortic arch which is positioned just anterior to it instead.

This study apart from determining feasibility of the method may produce enough data from ultrasound exams to develop/derive a more pre-cise algorithm than available today aiding in positioning the endotracheal tube in regards to anatomic-al landmarks (teeth, gums, lips) even without the use of ultrasound.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

US ETT (ultrasound endotracheal tube)

Subjects will have a brief (\< 15 minutes) ultrasound exam of the neck after intubation. The cuff of the endotracheal tube as well as the aortic arch will be identified. The distance between the two structures will be measured and recorded.

Group Type EXPERIMENTAL

US ETT (ultrasound endotracheal tube)

Intervention Type PROCEDURE

Subjects will have a brief (\< 15 minutes) ultrasound exam of the neck after intubation. The cuff of the endotracheal tube as well as the aortic arch will be identified. The distance between the two structures will be measured and recorded.
