Although the use of high-frequency units is routine in all surgical disciplines, there is still a justification for reminding users of the attendant risks. The most common injuries sustained by patients are burns caused by fault currents. Such risks increase when a combination of several electric devices is used, and in particular when the operation is performed with simultaneous anesthesiologic monitoring. All electrically conductive, direct or indirect contacts between the patient and the ground lead potential, and all connections resulting in a low resistance or a shorter distance between the active and "neutral" high-frequency electrode than the correct current pathway, may become competing "neutral" electrodes with high current densities. It is therefore imperative that all those involved should strictly observe the safety rules. The systematization of problem points is intended to introduce greater clarity into the relatively long list of admonitions, and to indicate possible organizational solutions.
尽管高频设备在所有外科领域的使用已很常规，但仍有必要提醒使用者注意相关风险。患者最常见的损伤是由故障电流导致的烧伤。当同时使用多种电气设备时，尤其是在进行手术并同步进行麻醉监测时，此类风险会增加。患者与接地导线电位之间的所有导电直接或间接接触，以及所有导致有源和“中性”高频电极之间电阻低或距离比正确电流路径短的连接，都可能成为具有高电流密度的竞争性“中性”电极。因此，所有相关人员必须严格遵守安全规则。对问题点进行系统化整理旨在使相对冗长的警示清单更加清晰，并指出可能的组织解决方案。
