Patient Unconscious

Answer this...

What advice should you give regarding the screening of a patient with no recorded medical history and who is unconscious or unresponsive?

If you have correctly answered the safety questions so far, you should have no problem with this one. The same contraindications apply. Make a visual check of the patient for superficial scars, and investigate the possibility of implanted or embedded objects with plain film x-rays. Can you rule out intra-ocular fragments, aneurysm clips or pacemakers without a plain film x-ray? Of course not. You can see how a careful and considered approach using your knowledge of MR safety can be applied step by step. Consider also heating effects and ear protection. Make sure a clinician responsible for the patient is present at all times.
