"Don''t worry, take your time. Director Peng, just said half. Please tell me about today''s operation." Wu Mian said.


    "Miss Wu, this is a film of cervical vertebra. Please give me a look." director Peng took out his mobile phone, found the prepared picture and handed it to Wu Mian.


    There are four position films of cervical spine and CT of cervical spine. Wu Mian looked at the image data and said, "you continue."


    "The patient had twice block anesthesia in a few months. No abnormality was found in the first and second planetary ganglion block, which was the third operation." director Peng continued, "the operation was smooth. After the injection of drugs, the patient complained of hand anesthesia and dizziness. Then..."


    "Director Peng, tell me more about the process of pushing medicine." Wu Mian looked at the film carefully and said.


    "The patient took the supine position and put a thin pillow under the shoulder. I stood on the patient''s affected side, pressed the tip of the middle finger of my left hand close to the upper edge of the sternoclavicular joint, and gently pressed down along the side of the tracheal wall 2.5cm above the sternoclavicular joint to push the sternocleidomastoid muscle and its deep common carotid sheath to the outside."


    "When the fingertip is pressed down, the transverse process of the seventh cervical vertebra can be touched. The right hand holds a 3.5cm long No. 7 puncture needle, and vertically pierces the skin along the fingertip of the middle finger of the left hand. The needle enters the bone, which is the transverse process of the seventh cervical vertebra. Slightly withdraw the needle, draw back without blood and cerebrospinal fluid, and inject 10ml diluted lidocaine."


    Director Peng can almost recite the whole process.


    Now recount it again, think about your operation process carefully, there is no problem at all, and every step is clear and clear.


    Ten thousand old drivers can''t be reached by anyone.


    This is stellate ganglion block anesthesia. The time is relatively short. Peng Peng can do nearly 10000 cases. It would be nice if surgery were changed and many doctors could do thousands of cases in a lifetime.


    There must be no problem with the process just described!


    Only the first and second times of the whole process, a small amount of fresh blood seems to be wrong.


    At that time, there was a small amount of fresh blood in the syringe. He thought it was capillary rupture, which should have nothing to do with the vertebral artery. Therefore, director Peng doesn''t care, and tries to explain the whole process concisely and concisely.


    "What are the complications of stellate ganglion block?" asked Wu Mian.


    "Local anesthetic poisoning; total spinal anesthesia; recurrent laryngeal nerve block; phrenic nerve block or spasm; bleeding and hematoma formation; and pneumothorax."


    "Well, almost so." Wu Mian nodded.


    "Miss Wu..."


    "It is very dangerous for the needle to enter the vertebral artery by mistake and total spinal anesthesia. Both of them will have cardiac and respiratory arrest. However, total spinal anesthesia pierces the arachnoid and the drug solution mistakenly enters the subarachnoid space. The main feature is the rapid development of extensive sensory and motor nerve block after drug injection."


    "Director Peng, let me ask you something." Wu Mian put Peng Peng''s cell phone down, looked at him seriously and said, "since you know there are these complications, why don''t you have a ventilator in the clinic?"


    "..." Peng Peng wanted to say something, but his lips moved slightly, and finally swallowed all his words.


    "Patients with serious complications will have hypotension and bradycardia, and sometimes stop breathing. The patient with planetary ganglion block immediately experienced hand numbness, dizziness and gradually dyspnea after injection of drugs. After 5 minutes, he stopped breathing, lost consciousness, and decreased blood pressure and heart rate significantly."


    "Normally, it''s all expected, just the probability. In this case, we must intubate immediately. You may say that the ventilator is too expensive and the hospital doesn''t match it." Wu Mian smiled and tapped his right finger on the table, "but in case of an accident, do you think the director in charge will think it''s his fault?"


    "..." Peng Peng was in a cold sweat.


    At first, he thought that Mr. Wu was just an academic doctor. Most doctors who came back from studying abroad were academic. They thought that the machine was not good enough and kept complaining that the head nurse had to take care of things such as wearing gloves.


    But the next words prove that Mr. Wu is clear about all kinds of clinical tricks.


    "Maybe the hospital leaders who refused your request at that time have retired. Even if they don''t retire, what evidence do you have? Application report? It''s strange that the hospital leaders can take care of you." Wu Mian said with a smile. "Domestic hospital leaders are good at turning small things into big things. There are not many leaders who can do things peacefully."


    Speaking of this, not only Peng Peng, but also Zhang Zimo and director Qian have a sense of confidant. Mr. Wu is really a clinician and knows that clinical work is difficult to do.


    "But!" Wu Mian raised the volume slightly, and the strength of his right finger hitting the table increased a bit at the same time.


    "The work is not meticulous. This is your problem. If you don''t have a ventilator, you can intubate first. If you don''t have an endotracheal intubation, you can use an air bag first. You don''t have anything ready. Are you trying your luck?"


    Wu Mian looked at Peng Peng jokingly and looked at him. Director Peng immediately lowered his head and didn''t dare to look at Wu Mian''s eyes.


    "No accident, that''s lucky. Once an accident happens, the whole business may be delayed." Wu Mian smiles, and his tone is not as severe as that of video guidance rescue. "Many years ago, when some cities just carried out painless gastroenteroscopy, it was because the preparation work was not enough that the patients died."


    This... Is true, not to mention many cities, even several branches of Provincial Medical University.


    The profession of doctor is different from other professions. When accumulating experience, it is particularly prone to various problems. The big deal in other industries is economic loss, while the cost of the medical industry is human life.


    We can''t expect everyone''s level to reach the world''s top level like a machine. In that case, the world is no longer what it is.


    However, Wu Mian''s cognition is that any operation should be cautious, cautious, cautious, careful. Even if you have OCD, you can''t be too careful, and any preparation is not superfluous.


    Peng Peng, an old driver of 10000 games, can''t avoid mistakes. What about others?


    However, if new technologies are not developed for fear of complications, it will be a slackening of efforts, and the residents within the radiation range of the hospital will have to pay a greater intangible price.


    "Miss Wu, you''re right." director Peng bowed his head and said in some frustration.


    "Ha ha." Wu Mian smiled, "I just want to say a few more words. I have another question. I want to ask director Peng you."


    “……”


    Peng Peng''s heels are cold.


    Different from the criticism of the hospital leaders, those are laymen guiding experts and will only oppress people.


    Mr. Wu, this is another situation. Listening to him, stellate ganglion block anesthesia is more expert than his 10000 field old driver.


    Peng Peng is really afraid of Wu Mian. It''s not surprising that Mr. Wu scolds when he slaps the table. He even pastes the coffee cup in front of him on his face.
