例1:女,35岁,于2005年9月15日行左侧乳癌根治术,负极板置于左腋后线与第十二肋交点周围。手术结束,麻醉作用消失后,左侧背部疼痛,查体见该处2cm×2cm水泡伴周围红肿。分析原因,负极板虽一小部分置于肋骨处,但骨骼易致电流回路不良。回忆手术时不断调大输出功率2次,致使阻抗在肋骨处出现小范围分布,肋骨附着处温度急剧升高,造成皮肤烧伤。
Example 1: Female, 35 years old, on the left on September 15, 2005 underwent radical mastectomy. The negative plate was placed around the intersection of the left axillary line and the twelfth rib. After surgery, anesthesia disappeared, the left back pain, physical examination see the Department 2cm × 2cm blisters around with swelling. Analysis of reasons, although a small part of the negative plate placed in the ribs, but the bone is likely to cause poor current loop. Memorize the operation continue to increase the output power of 2 times, resulting in a small impedance distribution in the ribs at the ribs attached to a sharp increase in temperature, resulting in skin burns.
