Monitoring: With the ICU MRI-compatible monitor, you can monitor ECG (which will have a lot of artefact), NIBP or invasive pressures, SpO2, and capnography. At this stage, we do not have anaesthetic agent monitoring. The risks of awareness in a non-paralysed patient receiving volatile agents is low, as are the potential consequences of awareness given that the patient is not undergoing surgery. The master monitor stays in the scanner with the patient. The slave monitor sits, with you, outside the scanner in the control booth. If, for clinical reasons, you wish to sit in the scanning room with the patient, this is fine. The monitor employs a similar logic to the Datex monitors in theatre i.e. a control wheel which is rotated and then pressed to confirm the – selection. Recovery: Transport the patient to main PACU after the scan. The anaesthetist will need to decide whether to allow the patient to emerge and be extubated in the MRI suite before transport, or to transport the patient anaesthetised. Either is preferable to allowing the patient to emerge en route. If the decision is to transport the patient anaesthetised, then a propofol infusion, or manually administered boluses will be required. For the transport, take with you the grab bag” and whatever drugs “airway you think you might need (or the whole drug trolley if you have an extra pair of hands).
