Study Overview

Brief 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.

Arms & Interventions

Children <= 1 years old

Experimental

Pediatric patients <= 1 years old of age scheduled for surgery in the prone position

Intervention: Exploration of optimal PEEP in supine and prone position (Other)

Outcomes

Primary Outcomes

Optimal PEEP level at spine position

Time Frame: 10 minutes after intubation (supine)

Optimal PEEP level (cmH2O) determination using electrical impedance tomography at supine position

Optimal PEEP level at prone position

Time Frame: 1 hour after prone positioning (prone)

Optimal PEEP level (cmH2O) determination using electrical impedance tomography at prone position

Secondary Outcomes

  • pulmonary opening pressure measured using Electrical impedance tomography(until 1 hour after prone positioning)
  • Dynamic compliance measured using Electrical impedance tomography(until 1 hour after prone positioning)
  • regional ventilation delay measured using Electrical impedance tomography(until 1 hour after prone positioning)
  • atelectasis/overdistension ratio measured using Electrical impedance tomography(until 1 hour after prone positioning)
