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.
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
