Radiofrequency Scanning for Retained Surgical Items Can Cause Electromagnetic Interference and Pacing Inhibition if an Asynchronous Pacing Mode Is Not Applied.

ABSTRACT

Radiofrequency (RF) scanning is an increasingly popular method of detecting retained surgical items. RF systems are generally regarded as safe but have the potential to cause electrical interference with pacemakers. This may lead to serious adverse events, including asystole. We present a case of an RF system used with a temporary pacemaker resulting in asystole. With the use of RF devices becoming widespread, it is important for all operating room personnel to recognize the potential for pacemaker interference from RF scanning devices and the requirements for asynchronous pacing when these devices are in use.
