Determination of Optimal Mask Ventilation Mode in Pediatrics Using Real-time Ultrasonography

Not Applicable

• Conditions: Ultrasound; Ventilator Lung
• Interventions: Other: Peak inspiratory pressure; Other: Peep 5cmH2O

• Registration Number: NCT03881033
• Lead Sponsor: Ajou University School of Medicine

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.
