   Afraid that Geng would be stimulated, Ren Chongda led the students to rest in the doctor\'s office to wait for news.

   Chest pain, ECG did not show any abnormality such as myocardial infarction, but the heart rate was relatively fast. The initial cause was suspected to be bronchitis and orthopedic problems, and no one from the cardiothoracic surgery department was called again. The situation actually appears to be better and not life-threatening for the time being. But when the patient complains of pain, the family must be anxious. How do doctors handle it. For this kind of neuralgia, in addition to surgery to remove the cause, the drug can only be given analgesics or even a local seal (local anesthesia and other drugs are injected into the nerve-involved area for an analgesic and anti-inflammatory treatment).

  The painkiller can\'t be beaten indiscriminately. Painkillers are basically addictive, and only temporary pain relief cannot eradicate the cause. Domestic clinicians have always used it very cautiously. . The condition of the patients inside is worrying.

   "Cao Yong." Knowing that he was coming, Ren Chongda asked the monitor to accompany him, and he came out of the office to call him.

  Cao Yong turned around and asked his insider: "What\'s the condition of the patient?"

Ren Chongda said: "Chang Jiawei didn\'t call you, did he? He said last night that he might need an extraneurological consultation. He was going to send it for extra cranial CT today. After yesterday\'s film came out, what I can see now is At the level of the thoracic 5 to 7 vertebral bodies, there is an extradural space occupying the inner and outer spinal canal, which is considered to be an epidural tumor. It may be for this reason that Chang Jiawei calls it a CT of other parts.”

   Like epidural tumors, most of them are metastases, and there are many malignant tumors. Doctors must be careful. Surgery for malignant tumors is different from surgery for benign tumors. Like spine surgery, if it is judged to be malignant, the first consideration is not to remove the tumor, but to think about how to decompress the patient to prolong the physiological function of the patient\'s survival period and improve the happiness index of the survival period. The resection is of little significance. If it is benign, it should be removed as cleanly as possible to prevent recurrence.

   "Where is the film, I\'ll watch it again." Cao Yong said.

   Ren Chongda took him to the office. The others followed behind Cao Yong like little followers.

  The films from last night were taken out and hung on the light board in turn. Due to the distance yesterday, I couldn\'t see clearly. Today I finally had the opportunity to see the patient\'s film up close, Xie Wanying seized the opportunity to stand a little bit forward. Who made the orthopedic film look more complicated than other departments. Think of just a single vertebra. Anyone who has read anatomy knows that its morphological structure is already very complex. Each bone in the human body has its own special shape and special physiological meaning. It is as difficult to figure out the meaning of a bone as it is to study an organ.

   "Here, here." Ren Chongda helped Cao Yong point to the lesion, so that Cao Yong could grasp the key points of the case faster in a short time.

  Cao Yong watched the film and stayed silent.

   "If it is a metastatic tumor, is it better to do whole body CT?" Ren Chongda asked his opinion.

   Metastases are not necessarily transferred from outside the brain, and it seems that the majority of spinal metastases are transferred from the brain.

  While waiting for Senior Brother Cao to express his opinion, Xie Wanying could hear the surrounding students in her own class discussing in private first.
