详细描述
Methodology: Methods, techniques and tools provided. Describe the design, study population, materials, procedures and analysis plan:
EcoID is a study designed as an adaptive controlled clinical trial with a first phase of superiority and a second phase of non-inferiority with change of control, of parallel groups, random assignment and blinding of investigators measuring outcome.
A Bayesian statistical approach will be used for the analysis and inferences of the information obtained from the clinical trial. The use of an adaptive study is justified given that there is uncertainty if the sequential strategy is superior to palpation, so performing the sequential experiment optimizes sample collection. In case the intervention does not pass phase 1, it is not necessary to expose more patients to compare the intervention by the second control.
By using a Bayesian statistical approach, it is possible to use the phase 1 sample as a prior probability distribution.
Therefore, the adaptive sample of phase 2 is optimized, achieving the best statistical performance with the least amount of time and resources, benefits found in this type of design The study population will be adult patients of the IPS Universitaria, who accept participation in the study and sign the informed consent.

结局指标
主要结局
Proportion of adequate cricothyroid membrane identification by group
时间窗: through study completion, an average of 30 minutes
Adequate Identification of the cricothyroid membrane For the present study, it is defined as the concordance between the marking performed by any of the interventions and the marking performed by an expert. This must have a distance of less than 5 mm both in the axial and longitudinal planes. An expert in the field is defined as a professional who works using advanced airway management strategies, and has published on airway ultrasonography and/or performs a CUSUM curve for MCT identification \>90%.
次要结局
- Longitudinal deviation(through study completion, an average of 10 minutes)
- Lateral deviation in mm(through study completion, an average of 10 minutes)
- Participant satisfaction(through study completion, an average of 10 minutes)
- Satisfaction of the administrators of the intervention(through study completion, an average of 10 minutes)
- Degree of difficulty(30 minutes)
- Time to detection(through study completion, an average of 10 minutes)
- Perception of adherence to the technique(through study completion, an average of 10 minutes)
