Lateral Position MRI in Preterm Infants, an Observational Study

Lateral Position for Premature Babies Undergone Sedation During Magnetic Resonance Imaging: an Observational Study

The goal of this observational study is to evaluate safety of sedation in lateral position in premature babies undergone MRI. The main question it aims to answer are:

• number of apneas during sedation
• Maintenance of eupnea during deep sedation

Premature babies will be sedated in lateral position during Magnetic Resonance Imaging. During procedure we provide a close control about eupnea maintenance (SaO2 and EtCO2) in order to verify the safety of laying.
