Surgical energy-based devices emit energy, which can interfere with other electronic devices (eg, implanted cardiac pacemakers and/or defibrillators). The purpose of this study was to quantify the amount of unintentional energy (electromagnetic interference [EMI]) transferred to an implanted cardiac defibrillator by common surgical energy-based devices.
A transvenous cardiac defibrillator was implanted in an anesthetized pig. The primary outcome measure was the average maximum EMI occurring on the implanted cardiac device during activations of multiple different surgical energy-based devices.
The EMI transferred to the implanted cardiac device is as follows: traditional bipolar 30 W .01 ± .004 mV, advanced bipolar .004 ± .003 mV, ultrasonic shears .01 ± .004 mV, monopolar Bovie 30 W coagulation .50 ± .20 mV, monopolar Bovie 30 W blend .92 ± .63 mV, monopolar instrument without dispersive electrode .21 ± .07 mV, plasma energy 3.48 ± .78 mV, and argon beam coagulator 2.58 ± .34 mV.
Surgeons can minimize EMI on implanted cardiac defibrillators by preferentially utilizing bipolar and ultrasonic devices.
基于手术能量的设备会发射能量，这可能会干扰其他电子设备（如植入式心脏起搏器和/或除颤器）。本研究的目的是量化常见的基于手术能量的设备传输到植入式心脏除颤器的无意能量（电磁干扰[EMI]）量。
将经静脉心脏除颤器植入一只麻醉的猪体内。主要结局指标是在激活多种不同的基于手术能量的设备期间，植入式心脏设备上出现的平均最大电磁干扰。
传输到植入式心脏设备的电磁干扰如下：传统双极30W为0.01±0.004mV，先进双极为0.004±0.003mV，超声刀为0.01±0.004mV，单极博威30W凝血为0.50±0.20mV，单极博威30W混合为0.92±0.63mV，无分散电极的单极器械为0.21±0.07mV，等离子体能量为3.48±0.78mV，氩束凝固器为2.58±0.34mV。
外科医生可通过优先使用双极和超声设备，将植入式心脏除颤器上的电磁干扰降至最低。
