Preventing Hypoxemia With Manual Ventilation During Endotracheal Intubation (PreVent) Trial (PreVent)

12. september 2018 oppdatert av: Matthew Semler, Vanderbilt University Medical Center
Complications are common during endotracheal intubation of critically ill adults. Manual ventilation between induction and intubation ("bag-valve-mask" ventilation) has been proposed as a means of preventing hypoxemia, the most common complication of intubation outside the operating room. Safety and efficacy data, however, are lacking. PreVent is a randomized trial comparing manual ventilation between induction and laryngoscopy to no manual ventilation between induction an laryngoscopy during endotracheal intubation of critically ill adults. The primary efficacy endpoint will be the lowest arterial oxygen saturation. The primary safety endpoints will be the lowest oxygen saturation, highest fraction of inspired oxygen, and highest positive end-expiratory pressure in the 24 hours after the procedure.

Detaljert beskrivelse

PreVent is a prospective, parallel-group, pragmatic, randomized trial comparing manual ventilation between induction and laryngoscopy to no manual ventilation between induction an laryngoscopy during endotracheal intubation of critically ill adults. The primary aim of the PreVent trial is to compare the effect of manual ventilation between induction and intubation versus no manual ventilation on the lowest arterial oxygen saturation experienced by critically ill adults undergoing endotracheal intubation. The PreVent trial is anticipated to begin enrollment in January 2017 and will enroll adults undergoing endotracheal intubation with sedation and/or neuromuscular blockade in participating units. Patients will be randomized 1:1 to manual ventilation versus no manual ventilation. In the manual ventilation group, manual ventilation using a bag-valve-mask will be provided from the time of induction until the time of endotracheal intubation, except during laryngoscopy. In the no manual ventilation group, no manual ventilation will be provided between induction and endotracheal intubation, except for the treatment of hypoxemia. The primary efficacy endpoint will be the lowest arterial oxygen saturation during the procedure. The primary safety endpoints will be the lowest oxygen saturation, highest fraction of inspired oxygen, and highest positive end expiratory pressure in the 24 hours after intubation. Conduct of the trial will be overseen by a Data Safety Monitoring Board. An interim analysis will be performed after the enrollment of 175 patients. The analysis of the trial will be conducted in accordance with a pre-specified statistical analysis plan made publicly available prior to the conclusion of enrollment. The initial planned enrollment of 350 patients was increased by the Data and Safety Monitoring Board at the interim analysis to a final planned enrollment of 400 patients.

Aktiv komparator: Manual Ventilation
Beginning after the administration of sedation/neuromuscular blockade, manual ventilation will be provided by bag-valve-mask until the initiation of laryngoscopy. In patients requiring more than one attempt at laryngoscopy, bag-valve-mask ventilation will resume between laryngoscopy attempts.
Annen: Manual Ventilation
Beginning after the administration of sedation/neuromuscular blockade, manual ventilation will be provided by bag-valve-mask until the initiation of laryngoscopy. In patients requiring more than one attempt at laryngoscopy, bag-valve-mask ventilation will resume between laryngoscopy attempts.

  • Bag-valve-mask ventilation
Aktiv komparator: No Manual Ventilation
Between the administration of sedation/neuromuscular blockade and intubation, ventilation will not be provided unless the patient experiences an arterial oxygen saturation less than 90%. For patients who experience an oxygen saturation less than 90% after induction, bag-valve-mask ventilation may be provided.

If the patient is receiving assisted ventilation at day 28 or dies prior to day 28, VFD will be 0. If a patient is discharged while receiving assisted ventilation, VFD will be 0.

For patients who return to an ICU and are subsequently discharged prior to day 28, ICU-free days will be counted from the date of final ICU discharge. All data will be censored at the first of hospital discharge or 28 days.
