Determination of optimal positive end‐expiratory pressure using electrical impedance tomography in infants under general anesthesia: Comparison between supine and prone positions
Authors' conclusion
The prone position required higher positive end-expiratory pressure than the supine position in mechanically ventilated infants under general anesthesia.
Study context
- Population
- Infants under GA scheduled for surgery in the prone positionanalysed
- Participants
- 30 participants
- Exposure
- Prone vs supine position
- Outcome
- Optimal PEEP determined by EIT (decremental trial)
Methodological detailssingle-centre
- Single-centre
Main finding
As reported in the abstract
EIT-based optimal PEEP
P < 0.001
Observational data: associations, not effects.
Further findings
Electrical impedance tomography (EIT)- vs compliance-based optimal PEEP
- Significant differences between EIT- and compliance-based optimal PEEP
Airway pressures (peak, mean, plateau, driving) · up to 1 h after prone positioning
- Increased in prone vs supine
Centre of ventilation
- Ventral–dorsal ventilation balance improved
