bougie or stylet in patients undergoing intubation emergently (bougie)

Conditions: Acute Respiratory Failure

Summary: complications are common during tracheal intubations performed outside of the operating room. successful intubation on the first attempt has been associated with a lower rate of procedural complications, but the proportion of critically ill patients intubated on the first attempt during tracheal intubations outside of the operating room is less than 90%. the bougie, a thin semi-rigid tube that can be placed into the trachea, allowing a seldinger-like technique of intubating a patient's airway, has been traditionally reserved for difficult or failed airways. however, a recent single center trial of adult patients intubated in an emergency department demonstrated that use of the bougie on the first attempt improved intubation success, compared to use of a traditional stylet. theinvestigators propose a multi-center randomized trial to compare first-attempt bougie use versus endotracheal tube with stylet use for tracheal intubation of critically ill adults in the ed and icu.

the bougie trial is a prospective, parallel group, pragmatic, randomized trial comparing the effect of bougie use versus endotracheal tube with stylet use on the incidence of successful intubation on the first attempt among adults undergoing urgent or emergent tracheal intubation. patients admitted to the study units who are deemed by their clinical team to require intubation and fulfill inclusion criteria without meeting exclusion criteria will be randomized 1:1 to use of a bougie or use of an endotracheal tube and stylet on the first attempt at intubation. all other decisions regarding airway management, including the choice to use a bougie or endotracheal tube and stylet on subsequent attempts, will remain at the discretion of the treating provider. the trial will enroll 1,106 patients. conduct of the trial will be overseen by a data safety monitoring board. an interim analysis will be performed after the enrollment of 553 patients. the analysis of the trial will be conducted in accordance with a pre-specified statistical analysis plan, which will be submitted for publication or made publicly available prior to the conclusion of enrollment. the primary outcome is successful intubation on the first attempt the secondary outcome is severe hypoxemia (lowest arterial oxygen saturation between induction and two minutes following intubation of less than 80%)

Eligibility criteria:
inclusion criteria: 1. patient is located in a participating unit of an adult hospital 2. planned procedure is tracheal intubation with sedative administration (or tracheal intubation without sedative administration during cardiac arrest) 3. planned operator is a clinician expected to routinely perform tracheal intubation in the participating unit 4. planned laryngoscopy device is a non-hyperangulated laryngoscope blade exclusion criteria: 1. patient is pregnant 2. patient is a prisoner 3. urgency of intubation precludes safe performance of study procedures 4. operator feels an approach to intubation other than use of a bougie or use of an endotracheal tube with stylet would be best for the care of the patient 5. operator feels use of a bougie is required or contraindicated for the care of the patient 6. operator feels use of an endotracheal tube with stylet is required or contraindicated for the care of the patient
