Not Applicable
Recruiting
Conditions
Acute Respiratory Failure Requiring Intubation

Procedure: First intubation attempt with endotracheal tube plus bougie
Procedure: First intubation attempt with endotracheal tube alone
Registration Number
NCT06307392
Lead Sponsor
Nantes University Hospital
Brief Summary

Emergency intubation is routinely performed in the prehospital setting. Airway management in the prehospital setting has substantial challenges, such as hostile environment or lack of technical support in case of first attempt intubation failure, and inherent risk of complications, such as hypoxemia, aspiration or oesophageal intubation. This risk is higher when several attempts are needed to succeed endotracheal intubation. Thus, a successful first attempt intubation is highly desirable to avoid adverse intubation-related events. Noteworthy, prehospital emergency intubation is associated with a lower rate of first attempt intubation success when compared to emergency intubation in the emergency department (ED). Research is needed to overcome the specific challenges of airway management in the prehospital setting, and to improve the safety and efficiency of prehospital emergency intubation. Literature reports that the use of assistive devices such as bougie may increase the rate of first-attempt intubation success in the ED. To date, no randomized trial has ever studied this device in the prehospital setting. Thus, the aim of the BETA trial is to compare first attempt intubation success facilitated by the bougie versus the endotracheal tube alone in the prehospital setting.

Secondary Outcome Measures
NameTimeMethod
Occurrence of cardiac arrestWithin 1 hour following intubation
Occurrence of deathWithin 1 hour following intubation
Number of patients for whom the placement of an endotracheal tube was not possible in the pre-hospital settingWithin 30 minutes following first blade introduction
Occurrence of hypoxiaWithin 1 hour following intubation

SpO2 (pulsed oxygen saturation) \<90%

Occurrence of change in SpO2 of more than 3% from the time of induction to 2 minutes after confirmation of correct tube placementWithin 15 minutes following induction
Number of laryngoscopies attempts to achieve correct endotracheal tube placementWithin 30 minutes following first blade introduction
Difficulty perceived by the operator on first intubation attemptWithin 10 minutes following blade introduction

3-point Likert scale

Occurrence of bradycardiaWithin 1 hour following intubation

Heart rate \<50 bpm

Occurrence of pulmonary aspirationsWithin 1 hour following intubation
Occurrence of severe cardiovascular collapseWithin 1 hour following intubation

Systolic blood pressure less than 65mmHg recorded at least once or less than 90 mmHg lasting 30 minutes despite 500-1,000 ml of fluid loading (crystalloids) or requiring introduction or increasing doses by more than 30% of vasoactive support

Time between blade introduction to the confirmation of a correct tube placementWithin 15 minutes following blade introduction

In minutes. The correct position of the endotracheal tube is confirmed by detection of end-tidal carbon dioxide.

Change in SpO2 (pulsed oxygen saturation) from the time of induction to lowest SpO2 up to 2 minutes after confirmation of correct tube placementWithin 15 minutes following induction

In percentage

Cormack-Lehane grade of glottic view at first intubation attemptWithin 10 minutes following first blade introduction
Occurrence of injuriesWithin 24 hours following intubation

Occurrence (yes/no) of injuries related to the intubation:

mucosal bleeding, laryngeal, tracheal, bronchial, mediastinal or oesophageal injuries

Occurrence of complicationsWithin 48 hours following intubation

Occurrence (yes/no) of complications related to the intubation:

aspiration pneumonia (new opacity on chest imaging within 48 hours after intubation, in comparison to the first chest imaging after hospital admission), pneumothorax (new air collection within the pleural cavity on chest imaging)

Change of SpO2/FiO2 ratio (pulsed oxygen saturation / fraction of inspired oxygen) between the time of confirmation of correct tube placement and the minimum ratioWithin one hour after confirmation of correct tube placement

SpO2/FiO2 collected every 10 minutes to determine the minimum ratio
