Recruitment manoeuvres, consisting of sustained inflations at high airway pressures, have been advocated as an adjunct to mechanical ventilation in lung protective ventilation strategies to prevent the collapse of the lung.

This study aims to determine the safety and efficacy of a recruitment manoeuvre, by considering its impact on gas exchange, hemodynamics and on the release of systemic inflammatory mediators.

  • Echographic score of lung aeration [ Time Frame: T0 (baseline), T2 (1 hr), T4 (3 hrs) ]
  • Chest X-Ray [ Time Frame: T6 (24 hrs) ]

Secondary Outcome Measures:
  • Levels of IL-1, IL6, IL-8, IL-19, TNFa in the bronchoalveolar lavage [ Time Frame: T0 (baseline), T4 (3 hrs) ]

Estimated Enrollment: 10
Study Start Date: June 2010
Estimated Study Completion Date: December 2010
Estimated Primary Completion Date: October 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 40/30 Recruitment Manoeuvre
Patients with respiratory failure that will be first ventilated for 30 minutes according to standardized baseline protective ventilation and after that will receive the recruitment manoeuvre
Procedure: 40/30 recruitment manoeuvre
The ventilator will be switched to the continuous positive airway pressure (CPAP) mode and the pressure will be increased to 40 cmH20 for 30 seconds.
Other Names:
  • Recruitment Manoeuvres
  • ARDS open lung strategy
  • PEEP
Device: continuous positive airway pressure (CPAP)
continuous positive airway pressure (CPAP)

Detailed Description:
This prospective study will analyse the effects of a single recruitment manoeuvre in critically ill patients. Subjects will be mechanically ventilated patients needing alveolar RMs. After a period of stable lung protective approach ventilation, they will receive the "40/30" RM; lung mechanics, gas exchange, hemodynamics and plasmatic concentration of inflammatory mediators will be obtained before and after the RM. An ultrasound score, established from the lung aeration status of upper and lower parts of anterior and lateral chest wall, will also be calculated before and after the manoeuvre.In selected patients cytokine release in the bronchoalveolar lavage will be measured as well.
