Summary

Comparison of peak airway pressure and gastric insufflation in manual ventilation and pressure-controlled ventilation with facemask during anesthesia induction in children.

Conditions

  • Elective Urologic Surgeries

Interventions

OTHER

manual ventilation

Anesthesia will be induced by propofol 1mg/kg via intravenous line. Once loss of eyelash reflex occurred, ultrasonography of antral area will be started by same physician. After administration of muscle relaxant (rocuronium 0.2-0.4mg/kg), manual ventilation will be performed with respiratory rate 20 breathes/min, I:E ratio of 1:1 and tidal volume with 9-10mL/kg. The pop-off valve will be set at 15cmH2O at fixed gas flow of 500mL/min of oxygen. Pressure-controlled ventilation will be performed with respiratory rate 20 breaths/min, I:E ratio of 1:1 and peak airway pressure will be set to get a tidal volume of 9-10mL/kg. The peak airway pressure during facemask ventilation will be checked. Another physician will auscultate the epigastric area to detect gastric insufflation during facemask ventilation. Ultrasonography of antral area will be checked once again after 3 minutes of facemask ventilation.
