患者女,33岁,在全麻下行心内直视房缺修补术切皮后电凝止血时,置于患者鼻腔内的数字体温计(上海医用仪表厂)控头与鼻腔粘膜之间出现放电火花,鼻粘膜灼伤,传感器烧坏。疑高频电力接触电极与皮膜接触不良,查无误。更换测温控头(连同传感器),继续测温,当关胸电凝止血过程中.上述情况再次出现,且鼻温控头与导线之连接烧断,控头部分遗留鼻腔内,以后经口腔取出。本例造成灼伤的原因可能为高频电刀与接触电极之间接触不良,当其偶尔发生开路时,高频电流经电
Patient female, 33 years old, under general anesthesia, open heart surgery, atrial septal defect, electrocautery, and hemostasis after incision of the skin, a digital thermometer placed in the patient’s nasal cavity (Shanghai Medical Instrument Factory) between the control head and nasal mucosa discharge sparks The nasal mucosa burns and the sensor burns. Suspected high-frequency power contact electrodes and film contact bad, check correct. Change the temperature measuring head (with sensor), continue to measure temperature, when the chest electrocoagulation hemostasis process. The above situation reappears, and the connection of the nose temperature control head and the wire is blown, the control head part is left inside the nasal cavity, and then the oral cavity take out. The cause of burn in this case may be poor contact between the high-frequency knife and the contact electrode. When an open circuit occurs occasionally, the high-frequency current passes through the electricity.
