Ultrasound, Ventilator Lung
Conditions
Brief summary
The peak inspiratory pressure during face mask ventilation for general anesthesia is closely correlated with gastric insufflation. High pressure increases the amount of air in stomach and low pressure could decrease the tidal volume, therefore ideal pressure means the pressure guarantee adequate ventilation with minimal gastric insufflation. The aim of this study is finding the proper pressure and mode of face mask ventilation in pediatric patients.
Interventions
OTHERPeep 5cmH2O
Face mask ventilation with peak inspiratory pressure according to the group P7+5 means face mask ventilation with peak inspiratory pressure 7cmH2O plus PEEP 5 cmH2O.
OTHERPeak inspiratory pressure
Face mask ventilation with peak inspiratory pressure according to the group P12 means face mask ventilation with peak inspiratory pressure 12cmH2O without PEEP.
