Study of Interest on Cervical Ultrasound Exploration for Association With Difficult Intubation

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine if cervical ultrasound exploration can predict difficult intubation better than main validated clinical criteria.

Design Details

Primary Purpose: Diagnostic
Intervention Model: Single Group Assignment
Masking: Triple


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| No Intervention: Cervical ultrasound exploration<br>A cervical ultrasound exploration will be performed in all patients admitted for a planned surgery performed under general anesthesia during the stay in the postoperative room. | Procedure: Ultrasound cervical exploration<br>* The cervical ultrasound exploration will consist in the ultrasound measurement of the length between the hyoid bone and the skin and the length between the thyroid cartilage and the skin. The ultrasound cervical exploration will be performed in all patients admitted in the postoperative room after a planned surgery performed under general anesthesia.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Sensibility, Specificity, predictive positive and negative values of US cervical measures relationship between the hyoid bone and thyroid cartilage with difficult intubation | The measure of the length between the hyoid bone and the skin and between the thyroid cartilage and the skin will be measured using an ultrasound cervical exploration in all patients admitted in the postoperative room after planned surgery performed under general anesthesia. | Day 1 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Sensibility, specificity and predictive positive and negative values of validated clinical criteria for difficult intubation | The collect of usual clinical criteria of difficult intubation in postoperative room of patients who undergo a general anesthesia for a surgery | Day 1 | 
| Mortality and morbidity of difficult intubation | Collect any complications (hypoxia, hypotension, tooth breakage) assigned to a difficult intubation during general anesthesia for surgery. | Day 1 |
