Study Description

Brief 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.

  • Condition or Disease:Acute Respiratory Failure
  • Intervention/Treatment: Other: Bougie
    Other: Endotracheal Tube with Stylet
  • Phase: N/A
Detailed Description

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%)

Arms and interventions
Arm Intervention/treatment
Active Comparator: BOUGIE
For patients randomized to use of a bougie, the operator will use a bougie on the first attempt at intubation. If successful, an assistant will load an endotracheal tube over the bougie, and the operator (without removing the laryngoscope from the mouth) will guide the tube through the vocal cords to the desired depth in the trachea. If the bougie is not successfully placed in the trachea or the endotracheal tube cannot be successfully advanced over the bougie on the first attempt at intubation, the operator may use any approach during subsequent attempts at tracheal intubation.
Other: Bougie
disposable tracheal tube introducer of approximately 70 cm in length
Active Comparator: Endotracheal Tube with Stylet
For patients randomized to use of an endotracheal tube with stylet, the operator will use an endotracheal tube containing a removeable, malleable stylet, on the first attempt at intubation. Manipulation of the shape/curve of the endotracheal tube with stylet is at the discretion of the operator, however a "straight-to-cuff" shape and a bend angle of 25° to 35° is encouraged. The stylet will be left in place until the tube is advanced to the trachea. If the endotracheal tube with stylet is not successfully placed in the trachea on the first attempt at intubation, the operator may use any approach during subsequent attempts at tracheal intubation.
Other: Endotracheal Tube with Stylet

Outcome Measures
  • Primary Outcome Measures: 1. Number of intubations with successful intubation on the first attempt [ Time Frame: from induction to 2 minutes following tracheal intubation ]
    The primary outcome is successful intubation on the first attempt. Successful intubation on the first attempt is defined as placement of an endotracheal tube in the trachea (confirmed by standard means including capnography) following: (1) a single insertion of a laryngoscope blade into the mouth and (2) EITHER a single insertion of a bougie into the mouth followed by a single insertion of an endotracheal tube into the mouth OR a single insertion of an endotracheal tube with stylet into the mouth.
  • Secondary Outcome Measures: 1. Number of intubations with severe hypoxemia [ Time Frame: from induction to 2 minutes following tracheal intubation ]
    Defined as an oxygen saturation less than 80% during the time interval from induction to two minutes after completion of the intubation procedure
  • Other Outcome Measures: 1. Number of intubations with cardiac arrest within 1 hour following intubation [ Time Frame: within 1 hour following intubation ]
  • 2. Cormack-Lehane grade of glottic view on first attempt [ Time Frame: from induction to 2 minutes following tracheal intubation ]
    Grade 1: Full view of glottis Grade 2: Partial view of glottis Grade 3: Only epiglottis seen (none of glottis) Grade 4: Neither glottis nor epiglottis seen
  • 3. Number of laryngoscopy attempts [ Time Frame: from induction to 2 minutes following tracheal intubation ]
  • 4. Number of attempts at passing bougie [ Time Frame: from induction to 2 minutes following tracheal intubation ]
  • 5. Number of attempts at passing endotracheal tube [ Time Frame: from induction to 2 minutes following tracheal intubation ]

    Operator-reported difficulty will be reported by the operator immediately following intubation as one of three values on a three-point ordinal scale with 1 (easy) being the best score and 3 (difficult) being the worse score: easy moderate difficult
