Cables and electrodes can burn patients during MRIBY SUSAN LANGE, ARRT, MPH, AND QUYNH NHU NGUYEN, BS(Article reprinted from Nursing2006, Volume 36, Number 11, p. 18.) PATIENTS UNDERGOING magnetic resonance imaging (MRI) while wearing ECG electrodes attached to cables have received second- and third-degree burns on skin under the electrodes. These burns were discovered after the MRI, according to reports received by the Food and Drug Administration. What went wrong?The radiofrequency fields that occur during an MRI can heat ECG cables and electrodes, seriously burning skin under the electrodes. The burns can be severe enough to require plastic surgery. What precautions can you take?The number of MRI studies performed annually is consistently increasing. As the imaging technology advances, more patients require monitoring during study because of the type of study or their general condition. Patient monitoring requires the use of MRI-compatible equipment. To help reduce patient adverse events during an MRI, follow these steps:
Although you need to support the adverse event- reporting policy of your health care facility, you may voluntarily report a medical device that doesn’t perform as intended by contacting MedWatch at 1-800-FDA-1088 (fax: 1-800-FDA-0178) or online at http://www.fda.gov/medwatch/how.htm.
