[Anesthetic management for children undergoing magnetic resonance imaging (MRI) at Department of Anesthesia and ICU, National Center for Child Health and Development (NCCHD)].

We present here anesthetic management for children undergoing MRI at the Department of Anesthesia in NCCHD. Remaining motionless in the scanner of MRI is extremely important for data integrity because motion will blur the image. In patients who cannot remain still and in small children, general anesthesia or sedation is required for MRI. The MRI room is different from the conventional operating room as follows; the MRI machine emits the large sound continuously: the MRI room is the powerful magnetic field and the generation of radio frequency emissions necessitate the use of special equipment to provide continuous patient monitoring: the temperature in the MRI room is kept at 23 degrees to maintain the MRI machine: the patients positioned at the restricted area during the MRI scanning are hard to be accessed. We describe two cases of anesthetic management for children undergoing MRI by using propofol and in these cases we found that it should be better to follow the conventional setting for general anesthesia including monitoring system. Some hospitals encountered with serious complications such as cardiac arrest during MRI scanning under general anesthesia/sedation. MRI scanning under general anesthesia/sedation has a high risk due to the environment, indicating that we should be careful about the safety of the patients.
