Anesthesia for MRI in the paediatric patient.

The magnetic resonance imaging suite is a challenging environment for the anaesthesiologists, and carries inherent risks. Several factors account for this, including the remote location, the unique features of the magnetic resonance imaging scanner and patient-related factors. A systematic approach, similar to that of anesthesia provided in the operating room (i.e. proper fasting, informed consent, focused airway examination, medical and surgical history, family history, previous sedation experiences) is mandatory. Understanding the implications of the magnetic resonance imaging environment will facilitate ensuring the safety of the patient. A well-equipped anesthesia machine, standard monitoring (electrocardiogram, oxygen saturation and non-invasive blood pressure), trained personnel and adequate planning should be standard for all out of the operating room procedures. Finally, rigorous discharge criteria are recommended to detect residual sedation.
