In two patients undergoing open heart operations, electrochemical burns developed at the sites of connection to an external pacing system. Investigation revealed that failure of the pacing generator caused a small, continuous, direct current to pass through the patients, resulting in electrolysis at the sites of contact with the pacing and grounding wires. This electrolytic reaction was recreated in a mock pacing system and resulted in tissue injury and disintegration of the pacing wire. Guidelines to help recognize and prevent this complication are presented.
在两名接受心脏直视手术的患者中，与外部起搏系统连接的部位出现了电化学烧伤。调查显示，起搏发生器故障导致一小股持续直流电通过患者身体，在与起搏线和接地线接触的部位引发了电解反应。这种电解反应在模拟起搏系统中重现，并导致组织损伤和起搏线解体。本文提出了有助于识别和预防这种并发症的指南。
