Many patients who need surgical treatment are more afraid of “anesthesia” before surgery than they are of the surgery itself. They often have questions about anesthesia, such as: “Will general anesthesia affect my intelligence?” “Will people become stupid after having general anesthesia?” “Will general anesthesia be more dangerous than semi-anesthesia?” Some people even “specifically” ask the doctor, “I only receive half-body anesthesia, not general anesthesia,” or “Can I have surgery without anesthesia?” Questions such as these sometimes make it very difficult for anesthesiologists, even if they patiently explain to patients and their families, they may still be half-hearted, in fact, the development of modern medicine, anesthesia should not make you so afraid. A. Why is the fear of “anesthesia” more than the fear of “surgery”? Whether it is semi-anesthesia or general anesthesia there must be a way to use the drug into the body in order to play a role, the kind of folklore “a suction will be numb” drugs or ways actually do not exist, if there is really that magical drugs, will be widely promoted in medicine, and the world’s anesthesiologists do not yet have Such an ideal drug. The pain and a series of pathological stress reactions generated by surgery can have a very negative impact on the body, Hua Tuo scraped the bones for Guan Yu without anesthesia because there was no good anesthesia technology in ancient times but had to do so in order to save lives. Therefore, we must be anesthetized before surgery, and before the anesthesia must first be injected, that is, to be anesthetized, you must first small anesthesia, small anesthesia before the first injection, of course, the patient has to hurt a little, which has a “surgery does not hurt anesthesia pain” phenomenon. There is also a common misunderstanding of anesthesia, fearing that anesthesia affects intelligence, in addition to the mechanism and process of anesthesia is not understood, many people are still stuck in: “anesthesia injection, if the surgery is not done anesthesia drug effects, people will have to suffer” in the superficial understanding, do not know that the current anesthesia technology is a very mature and profound We can say that from the time the patient is on the operating table until he or she returns to the ward, the anesthesiologist is always by your side to help you eliminate pain and ensure safety. What is the basic process of anesthesia? The anesthesiologist will visit the patient before surgery to understand the patient’s condition and develop a suitable anesthesia plan based on the surgical procedure and the patient’s functional status. Each type of anesthesia has its own indications and contraindications. On the day of surgery, the patient enters the operating room, the anesthesiologist first induces anesthesia for you, and after the anesthesia effect takes full effect, the surgeon starts the surgery. The pathological changes of the disease during the surgery and the trauma of the surgery itself bring a continuous blow to the patient, and at this time it is up to the anesthesiologist to balance, and all anesthetic drugs have a certain degree of respiratory and/or circulatory mimicry, and the skill of the anesthesiologist is to give full play to the anesthetic effect of each drug while actively regulating respiration and supporting circulation to complete. Respiratory and circulatory mimicry is not a problem because anesthesiologists have reliable circulatory and respiratory support equipment and techniques. The anesthesia process is like the takeoff and landing of an airplane, with induction of anesthesia like takeoff and awakening like landing, and the anesthesiologist will be there for you until the patient returns safely to the ward. This is the reason why some people say that “the surgeon is in charge of the disease and the anesthesiologist is in charge of the life” during surgery. Of course, this is inaccurate, because intraoperative surgeons and anesthesiologists will definitely cooperate and work closely together to ensure the smooth operation, only the division of labor is different, each focus on it. Third, does general anesthesia affect intelligence? Is it more dangerous than half-body anesthesia? The general anesthetics used in modern anesthesia are all drugs that have little effect on the human body and are completely reversible, and can be completely excreted by human metabolism after surgery. In addition, general anesthesia and semi-anesthesia are two different types of anesthesia, each with a different scope of adaptation and different sites of action of the drugs, but the metabolic pathways are basically similar, and both are completely reversible drugs. General anesthesia will be safer than semi-anesthesia for children or patients who cannot remain quiet during surgery and for all types of major surgery. Sometimes the anesthesiologist will choose to combine shallow general anesthesia with semi-body anesthesia to take advantage of their respective advantages, both of which are reasonable choices depending on the specific situation. If the patient does not understand anesthesia and only relies on some superficial understanding to unreasonably request a certain type of anesthesia or emphasize not to make anesthesia, it will interfere with the doctor’s best treatment plan and eventually delay the treatment of the disease.
