In the movie “Killing Surgery”, the main character Clayton regained consciousness during the operation although he was anesthetized. He can feel the terrible pain and hear the dialogue between doctors and nurses. The trouble is that his body cannot move or make any cry for help…….
Clayton in the movie, What we experienced was not a dream, It is an extremely rare general anesthesia complication-intraoperative knowledge. To be exact, It refers to the conscious state of the patient under general anesthesia. After the operation, The patient can also recall the events related to the operation that occurred during the operation. The consequences known during the operation can be light or heavy. Severe cases can cause serious emotional and mental health problems, Some patients even have auditory hallucinations, anxiety, asphyxia and even dying memories. After watching this movie, Must feel the risk of anesthesia has increased by one point. But then again, The movie “Killing Surgery” exaggerates the thriller known during the operation. In fact, In the real operating room, The rate of knowing during general anesthesia is very low. Professor Yue Yun of the Department of Anesthesiology of Chaoyang Hospital conducted a survey on this topic. He selected a total of 11 101 patients undergoing general anesthesia from 25 hospitals. Ask them on the first and fourth days after the operation. The last thing you remember before entering anesthesia is what? After waking up from anesthesia, the first thing you remember is what. Do you remember whether something happened between the two events? Did you dream during the operation? During the operation, do you remember that the worst thing was what? According to the survey results, 46 patient did have intraoperative awareness, 255 patients dreamed during the operation (but not necessarily knew it during the operation). Many netizens have promised, I have experienced it personally, know it during the operation, But they can’t stand careful scrutiny. Most of them receive local anesthesia. For example, spinal anesthesia or epidural anesthesia (for example, cesarean section, appendix surgery and lower limb surgery), just because anesthesiologists give some sedative drugs, they enter a hazy or lethargy state, accompanied by some dreams or memories. So, who is prone to know during the operation? The answer is that people who have received anesthesia before, all patients who use intravenous anesthesia drugs. Do you know the people who are actively awakened? In some operations, the doctor will take the initiative to wake up the anesthetized patient. Talk to them, the patient can move his hands and feet. Why does the doctor need the patient to wake up? It is usually used in brain and spinal surgery. These parts are the [headquarters] of the human body. The brain controls the whole body and gives instructions. The spinal cord in the spine has an important function of uploading and distributing. The operation requires not only removal of lesions, It is also necessary to ensure that the normal parts are not damaged. Intraoperative wake-up is the most direct and effective method, It can check and ensure the integrity of neurological function, Make sure the damage to these [forbidden zones] is minimized. Although it sounds good, The demand for anesthesiologists is very high. To make a simple analogy, The difficulty of awakening during the operation is equivalent to letting a drunk wake up immediately and being able to answer questions with you like a flow of water. This requires not only complicated and accurate anesthesia management, but also the cooperation of the entire operation team. It is necessary to ensure the safety of the patient and the effect of the operation. Should I worry? At first glance, Intraoperative awareness and awakening are important factors in the process of operation, The patients are all awake. But in fact, There is a big difference between the two. Wake-up is the doctor’s initiative to wake up a person who is under anesthesia. Intentionally. Anesthesiologists control narcotic drugs precisely, It ensures that the patient has the lowest degree of pain when awakened, But also can quietly cooperate with the doctor’s instructions. Knowing during the operation is the patient who should be under anesthesia. Only to find that I could still hear the doctor talking. Feel the stimulation of pain, But he could not move his body to remind the doctor that he was in this state. Knowing during the operation is an anesthesia complication. The impact on patients varies from person to person. Not all intraoperative knowledge has malignant consequences. For example, When a patient calmly said to the doctor after the operation: I heard you guys talking during surgery, I also heard the tinkling of surgical instruments. But when you asked him, When you have what’s worse feelings, The answer he gave you is no, It means that this may be known during the operation and no adverse consequences have occurred. Don’t worry too much about it, This is a preventable complication, This mainly depends on perfect preoperative judgment and strengthening intraoperative management to achieve, Such as reducing equipment failures, Preventive use of sedatives before surgery, accurate judgment of anesthesia depth, reduction of unnecessary stimulation to patients during surgery, etc. For the average person, if you are likely to undergo surgery under general anesthesia, you may as well mention the term [know during surgery] to the anesthesiologist before surgery. This is not only an expression of your concern, but also a natural reminder.
