McGrath Mac Videolaryngoscope Versus Macintosh Laryngoscope for Orotracheal Intubation in Critical Care Unit

The aim of this study is to demonstrate that the rate of successful orotracheal intubation at first laryngoscopy will be higher in patients intubated with McGrath Mac videolaryngoscope compared to patients intubated with classical Macintosh laryngoscope in patients requiring an orotracheal intubation in ICU.

Primary outcomes

  1. Proportion of successful orotracheal intubation at first laryngoscopy

    Time frame: intubation procedure, an expected average of 15 minutes

    Number of successful intubation at first laryngoscopy in one arm/number of included patients in the same arm.

Secondary outcomes

  1. Proportion of successful orotracheal intubation all laryngoscopies pooled

    Time frame: intubation procedure, an expected average of 15 minutes

  2. Time to successful orotracheal intubation

    Time frame: intubation procedure, an expected average of 15 minutes

    Defined by the time between the beginning of induction (injection of anesthetic drugs) and the time of confirmation of the intratracheal nature of the endotracheal tube (defined as apparition of first inflexion on the expired carbon dioxide curve)

Other outcomes

  1. Cormack and Lehane grade

    Time frame: intubation procedure, an expected average of 15 minutes

  2. Percentage of glottic opening (POGO) score

    Time frame: intubation procedure, an expected average of 15 minutes

  3. Difficult Intubation

    Time frame: intubation procedure, an expected average of 15 minutes

  4. Resort to alternative intubation technique

    Time frame: intubation procedure, an expected average of 15 minutes

  5. Frequency of occurence of unexpected events

    Time frame: Discharge from Intensive Care unit, an expected average of 7 days

  6. Mechanical ventilation duration

    Time frame: Time from extubation, an expected average of 6 days

  7. Intensive Care Unit length of stay

    Time frame: Discharge from Intensive Care unit, an expected average of 7 days

  8. Hospital length of stay

    Time frame: Discharge from hospital, an expected average of 14 days

  9. Intensive Care Unit Mortality

    Time frame: Discharge from Intensive Care unit, an expected average of 7 days
