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.

Conditions

• Acute Respiratory Failure Requiring Intubation

Interventions

Type	Name	Description
PROCEDURE	First intubation attempt with endotracheal tube plus bougie	Use of a straight, malleable, semirigid bougie on first-attempt intubation. The required bougie is at least 60cm length, a coudé tip is recommended but not required. Operator may choose whether to bend the bougie prior to intubation. During laryngoscopy, the operator will insert the bougie into the trachea under direct or indirect visual control. If the bougie is successfully placed in the trachea, an assistant will load the endotracheal tube directly over the bougie while the operator will manually stabilize the bougie. Once the bougie has reached the mouth, the assistant will then stabilize the bougie, and the operator will advance the tube through the vocal cords to the adequate depth in the trachea, without removing the laryngoscope from the mouth. The operator will inflate the cuff and manually stabilize the tube. Then, the assistant will withdraw the bougie from the endotracheal tube. The use of a stylet is not permitted.
PROCEDURE	First intubation attempt with endotracheal tube alone	During laryngoscopy, the operator will insert the endotracheal tube alone into the trachea under direct or indirect visual control. The operator will advance the tube through the vocal cords to the adequate depth in the trachea, without removing the laryngoscope from the mouth. The operator will inflate the cuff and manually stabilize the tube. The use of a stylet is not permitted.
