Brief Summary

Objective: to compare the effect of alveolar recruitment manouver through stepwise increase and decrease in airway pressure or sustained 30 secondes 30 cmH2O continuous positive airway pressure on cardiac stroke volume estimated by oesophageal doppler in preload independent anesthetized patients scheduled for surgery.

Outcome Measures

Primary Outcomes (1)

  • cardiac stroke volume

    change in cardiac stroke volume during the alveolar recruitment manoeuver

    1 min

Secondary Outcomes (2)

  • arterial pressure

    1 min

  • recovery at 3 min

    3 min

Study Arms (2)

CPAP30

ACTIVE COMPARATOR

a 30 secondes 30 cmH2O continuous positive airway pressure applied after the orotracheal intubation will be checked and secured following induction of general anesthesia

Procedure: alveolar recruitment manoeuver

STEP30

ACTIVE COMPARATOR

a stepwise increase (+5 cmH2O) in postivie airway pressure from +5 cmH2O to +30 cmH2O and decrease (-5 cmH2O) from +30 cmH2O to +5 cmH2O applied after the orotracheal intubation will be checked and secured following induction of general anesthesia

Procedure: alveolar recruitment manoeuver

Interventions

alveolar recruitment manoeuver are recommended during general anesthesia to prevent pulmonary atelectasis

Masking Details
The patient will not know the allocation group because he will be anesthetised before randomisation. The care provider (anesthetist) will not know the allocation group because the intervention will be applied by an independent investigator not involved in care of the patient.
