Determination of Optimal Positive End-expiratory Pressure Using Electrical Impedance Tomography in Children Under General Anesthesia: Comparison Between Supine and Prone Positions

Determination of Optimal Positive End-expiratory Pressure Using Electrical Impedance Tomography in Children Under General Anesthesia: Comparison Between Supine and Prone Positions

The purpose of this study was to determine the appropriate positive end-expiratory pressure (PEEP) using electrical impedance tomography (EIT) in children under general anesthesia and to investigate whether there is a difference between the supine and prone positions.

Inclusion Criteria:

• Children <= years of age who are scheduled for surgery in the prone position under general anesthesia

Exclusion Criteria:

• Respiratory distress, bronchopulmonary dysplasia
• Pneumothorax
• Increased intracranial pressure
• History of airway surgery
• Cervical or thoracic surgery
• Pulmonary hypertension
