Radiofrequency ablation (RFA) is used to treat unresectable liver tumor. The authors described a case of RFA complicated by skin burn around a ground pad. A 70-year-old female underwent RFA of liver metastatic tumor under general anesthesia. Preoperatively, two ground pads were placed on the patient's right thigh and right calf after left lateral positioning. RFA was performed three times by 90 watts for 15 min each. At the end of surgery we noticed skin burn on the right thigh. It seems that electric current concentrated on the ground pad of the right thigh especially on the proximal side. In conclusion, two ground pads should be placed one on each thigh to distribute electric current.
射频消融术（RFA）用于治疗无法切除的肝肿瘤。作者描述了一例RFA并发接地垫周围皮肤烧伤的病例。一名70岁女性在全身麻醉下接受了肝转移瘤的RFA治疗。术前，在患者左侧卧位后，将两个接地垫分别置于患者右大腿和右小腿。RFA以90瓦功率进行了3次，每次15分钟。手术结束时，我们注意到右大腿皮肤烧伤。似乎电流集中在右大腿的接地垫上，尤其是近端。总之，应在每条大腿上各放置一个接地垫以分散电流。
