患者：李护士，我是今天刚入院的患者，医生要给我做冷冻治疗，我想了解一下。
P：Nurse Li，I am a new patient and was scheduled to have a cryotherapy today.Could you please tell me more details about this treatment？
护士：好的，氩氦冷冻消融术是一种微创超低温冷冻消融肿瘤的先进技术，也叫作“氩氦刀”。它在CT或B超定位引导下将氩氦刀准确穿刺进入肿瘤内，先用氩气，刀尖会急速膨胀产生制冷作用，在15秒内将病变组织冷冻至零下140℃～零下170℃，持续15～20分钟后，关闭氩气，再使用氦气，氦气在刀尖急速膨胀，急速加热处于超低温状态的病变组织，使其温度从零下140℃上升至零上20～40℃，从而施行快速热疗。持续3～5分钟之后，再重复一次，可杀死病变组织。其降温及升温的速度、时间，摧毁区域的尺寸与形状等，由B超或CT等实时监测，计算机精确设定和控制。
N：Well，argon-helium cryoablation is an advanced minimally invasive therapy that ablates tumors with ultra-low temperature.This treatment method is also called“argon-helium knife”.The argon-helium knife punctures accurately into the tumor under the guidance of CT or ultrasound.Argon is first rapidly expanded on the tip of the knife to generate a cooling effect，which can freeze the lesion tissues to minus 140℃～minus 170℃in 15 seconds.After 15 to 20 minutes，argon is turned off and helium is released on the tip of the knife to generate a rapid heating effect to the lesion tissues to rapidly elevate the temperature from minus 140℃to 20～40℃，for rapid hyperthermia.After 3 to 5 minutes，repeat the procedure to kill the lesion tissues.The rate and time of temperature changes，size and shape of the desired target tissues are all monitored by ultrasound or CT in real-time mode，and they are set and controlled precisely by the computer.
患者：这样的温度我受不了吧！
P：I don't think I can tolerate such a temperature change！
护士：不用担心，只是肿瘤部位温度有变化，您不会有太多感觉。(https://www.daowen.com)
N：Oh，don't worry about it too much.The temperature change only occurs in the targeted area，you can hardly feel it.
患者：那就好。
P：That's good.
护士：它对其他部位组织无损伤或损伤极小，这是有别于放疗和化疗的独特优点。
N：This treatment has no or minimal damage to other tissues，which is the unique advantage compared with radiotherapy and chemotherapy.
患者：谢谢，那我要注意一些什么吗？
P：Thank you，what should I pay attention to？
护士：治疗前需要禁食4小时，术前医生常规会给你开点止血药，现在请在病房等待。
N：You should not eat or drink 4 hours before the treatment.The doctor usually gives you some hemostatic medicine before the surgery.Now please wait in the ward.
患者：谢谢，我现在没有那么紧张了。
P：Thank you.I am much relieved now.
护士：不客气。
N：You are welcome.
