Protective ventilation (association of a tidal volume < 8 ml/kg with a positive end expiratory pressure) is poorly used in severe brain-injured patients. Moreover, a systematic approach to extubation may decrease the rate of extubation failure and enhance outcomes of brain-injured patients.

We hypothesized that medical education and implementation of an evidence-base care bundle associating protective ventilation and systemic approach to extubation can reduce the duration of mechanical ventilation in brain-injured patients.

Primary Outcome Measures:
  • Mechanical ventilatory free days [ Time Frame: Day-90 ] [ Designated as safety issue: No ]
    The number of ventilator-free days was defined as the number of days from day 1 to day 90 on which a patient breaths spontaneously and is alive

Secondary Outcome Measures:
  • Mortality [ Time Frame: day-90 ] [ Designated as safety issue: No ]
  • In-ICU mortality [ Time Frame: 90 days ] [ Designated as safety issue: No ]
  • Duration of mechanical ventilation [ Time Frame: 90 days ] [ Designated as safety issue: No ]
  • ICU free days at day 90 [ Time Frame: day 90 ] [ Designated as safety issue: No ]
    The number of ICU free days was defined as the number of days from day 1 to on which a patient is alive and not hospitalized in ICU

  • Acute respiratory distress syndrome / acute lung injury [ Time Frame: day-90 ] [ Designated as safety issue: No ]
  • Hospital acquired pneumonia [ Time Frame: day-90 ] [ Designated as safety issue: No ]
  • Blood gaz [ Time Frame: day-5 ] [ Designated as safety issue: No ]
    PaO2 (arterial pressure of oxygen) and PaCO2 (arterial pressure of dioxide of carbon)

  • Intracranial pressure [ Time Frame: day-5 ] [ Designated as safety issue: No ]
  • Glasgow outcome scale [ Time Frame: day-90 ] [ Designated as safety issue: No ]
  • Extubation failure [ Time Frame: day-90 ] [ Designated as safety issue: No ]
  • Ventilatory setting [ Time Frame: day-5 ] [ Designated as safety issue: No ]
    Tidal volume and Positive end expiratory pressure

Estimated Enrollment: 560
Study Start Date: July 2013
Estimated Primary Completion Date: June 2014 (Final data collection date for primary outcome measure)
Control phase (before)
Process of care and outcomes before the educational program
Training phase (after)

Process of care and outcomes after the educational program which recommends:

  • the use of tidal volume < 7 ml/kg and of a positive expiratory pressure = 6 to 8 cmH20 (centimeter of water)
  • extubation as soon as ventilatory weaning is associated with a glasgow coma scale equal or above 10 and cough

Detailed Description:

A before/after study design will be used. The before period (control phase) will consisted of all consecutive patients with severe brain-injury who were admitted to the participating ICUs.

During the interphase, all physicians, residents, physiotherapists and nurses will receive a formal training for the processes and procedures related to the 2 point bundle: protective ventilation and systematic approach to extubation (according to recommendation for the use of tidal volume < 7 ml/kg and of a positive expiratory pressure = 6 to 8 cmH20 (centimeter of water) and extubation as soon as ventilatory weaning is associated with a glasgow coma scale equal or above 10 and cought).

The after period consisted of all consecutive severe brain-injured patients admitted to the participating ICUs after the formal training.
