NCT02167334

Brief Summary

the aim of the study is to determine if Spontaneous Ventilation with Positive Pressure Ventilation (PPV) preoxygenation allows a longer non hypoxemic apnea time during panendoscopy compared to spontaneous breathing preoxygenation. the hypothesis is PPV extends the residual functional capacity of lung so it provides more oxygen during apnea.

Outcome Measures

Primary Outcomes (1)

  • non hypoxemic apnea time

    time the oxygen saturation is going down to 90% during apnea

    up to 5 minutes after stopping oxygenation

Secondary Outcomes (2)

  • surgical laryngoscopy frequency

    up to 15 minutes after stopping oxygenation

  • preoxygenation time

    up to 10 min after the start of oxygenation

Study Arms (2)

positive pressure ventilation

EXPERIMENTAL

Positive Pressure Ventilation with a 4 cmH2O inhale pressure, a positive end-expiratory pressure of 4 cm H2O, a trigger 2, an inspiratory slope of 0, an inhaled oxygen fraction of 100% administered at a 10 L / min flow.

Device: positive pressure ventilation

Oxygenation with simple breathing mask

ACTIVE COMPARATOR

spontaneously breathing preoxygenation with adapted face mask, to restrict leakage, at 10L/min oxygen, with inhaled fraction of 100% and a 2 L balloon volume.

Procedure: Oxygenation with simple breathing mask

Interventions

Positive Pressure Ventilation with a 4 cmH2O inhale pressure, a positive end-expiratory pressure of 4 cm H2O, a trigger 2, an inspiratory slope of 0, an inhaled oxygen fraction of 100% administered at a 10 L / min flow.

Also known as: non invasive ventilation (NIV)
positive pressure ventilation

Spontaneously breathing preoxygenation with adapted face mask, to restrict leakage, at 10L/min oxygen, with inhaled fraction of 100% and a 2 L balloon volume.
