Summary

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.

Conditions

• General Anesthesia

Interventions

Type	Name	Description
OTHER	Exploration of optimal PEEP in supine and prone position	1. General anesthesia is done in routine manner 2. A sensor for electrical impedance tomography (EIT) is applied around the patient's chest. 3. In supine position, lung recruitment maneuver is done, followed by decremental PEEP trial. Based on EIT parameter, optimal PEEP which induces minimal overdistension and collapse of lungs is determined. 4. One hour after prone position, optimal PEEP is determined again.
