NCT02238691

Brief Summary

Continuous positive pressure during anesthetic induction is today not routinely used partly a to the risk of gastric insufflation because of higher ventilatory pressures. However there are conflicting data with improvement of GERD symptoms in CPAP treated OSA patients. The investigators aim to compare the risk of gastric insufflation regarding mask ventilation technique, with or without positive end expiratory pressure. For measurements a High Resolution Impedance Manometry Catheter is used.

Outcome Measures

Primary Outcomes (1)

  • Level of inspiratory pressure for gastric insufflation

    One hour

Secondary Outcomes (1)

  • Pressure changes in the esophagus related to ventilation technique.

    One hour

Other Outcomes (1)

  • Pressure changes in the stomach after gastric insufflation

    One hour

Study Arms (2)

Mask ventilation with PEEP

EXPERIMENTAL

15 subjects will undergo anesthetic induction with application of PEEP of 10 cm H2O during mask ventilation.

Procedure: Mask ventilation with PEEP via a face mask device

Mask ventilation without PEEP

NO INTERVENTION

15 subjects will undergo anesthetic induction without PEEP during mask ventilation.

Interventions

15 subjects will undergo anesthetic induction with an application of PEEP of 10 cm H2O during mask ventilation via a face mask. 15 subjects will undergo anesthetic induction without PEEP during mask ventilation via a face mask.
