Many operations require general anesthesia, which not only relieves the patient’s pain and ensures the smooth progress of the operation, but also helps prevent permanent psychological trauma to the patient during the operation.
However, many people are very resistant to general anesthesia, thinking that it is like having died once, or worrying that general anesthesia will affect the health of the brain, reduce the level of intelligence and responsiveness in the future, and make people stupid and dumb. Does it really have such an impact? What is going on with general anesthesia? Let me explain clearly to you one by one.
There are two commonly used methods of general anesthesia, and there are three changes in the body after anesthesia
General anesthesia usually uses sedation and muscle relaxation drugs through intravenous injection or inhalation of the patient Way of administration.
After the drug enters the human body, it will act on the central nervous system. It can change the balance of chemicals in the brain, inhibit part of the brain activity, and achieve the effect of anesthesia.
After general anesthesia, the body will experience the following changes:
1. Loss of consciousness
After being anesthetized, the patient is in an unconscious "coma", and some general anesthesia can also stop breathing spontaneously_ span13span requires breathing support by a ventilator.
Patients will have no idea what will happen during this period. In very few cases, someone in the clinic will experience unexpected "intraoperative sobriety".
2. Loss of athletic ability
After general anesthesia, the muscles are completely relaxed, so that the body is unable to exert strength, and the body is in a stationary state, which is convenient for doctors to perform surgical operations. The effect of the operation will not be affected by the patient's actions.
3. Loss of perception
After general anesthesia,The patient does not perceive pain, etc., which can reduce physical and psychological trauma.
What happens before, during and after general anesthesia?
Before general anesthesia surgery, medical staff will ask the patient in detail about the patient’s medical history, allergy history, etc., and perform pre-operative examinations to comprehensively assess whether the patient is eligible for general anesthesia, and will inform the patient of general anesthesia and during surgery The possible risks, some diseases can allow the patient to choose the anesthesia method, such as whether it can be performed under semi-anaesthesia.
Patients also need to make corresponding physical preparations. For example, they generally need to start fasting the night before surgery, and some also need to abstain from water, which can avoid adverse complications caused by food reflux during anesthesia. Some patients also need an enema to empty the body of waste.
Before general anesthesia, it may be necessary to inject the patient or allow the patient to take some drugs orally to prepare for anesthesia.
During anesthesia surgery , medical staff will first monitor blood pressure, ECG monitoring , intravenous channel construction, oxygen mask, etc., and then administer intravenous injection and inhalation. Way to deliver anesthetic drugs into the patient's body. The patient will enter a state of loss of consciousness under the assisted breathing of the oxygen machine . In order to ensure breathing safety, the anesthesiologist will insert a thin tube into the throat if necessary.
During the whole process, medical staff will monitor the patient's anesthesia status and carry out necessary interventions in time.
Wake up after operation, due to differences in the dosage of anesthetics and physical functions, the specific time for different patients to wake up after anesthesia will vary, but generally, it takes 1 hour to 1.5 hours after entering the stage , You can gradually wake up, and your body's perception and basic activity ability will slowly return to the state before the operation. Some patients have poor metabolic capacity, and there may be a period of time when the consciousness is restored but the body is unable to move.
General anesthesia surgery will affect a person’s IQ,Does it make people stupid or stupid?
Many people believe that the drunkenness-like state of loss of consciousness during general anesthesia will damage the brain cells, causing people to experience decreased IQ, decreased memory, and become stupid and stupid in the future. Is it really?
There is no clear evidence that general anesthesia will affect a person’s IQ . In theory, maintaining a normal oxygen supply during the operation will not cause irreversible death of the vital organs of the body, especially the cells of the brain. As long as the drug components are metabolized in time, it will not have long-term effects on the body.
Although general anesthesia is of great significance, not everyone is suitable for general anesthesia.
Generally speaking, four conditions are not suitable for general anesthesia.
1. With cold symptoms
may cause continuous contraction of airway muscles and affect breathing. If it is an elective operation, generally speaking, it is better to undergo anesthesia 2-3 weeks after the cold is cured.
2. hyperthyroidism
Patients with hyperthyroidism undergoing general anesthesia are prone to hyperthyroidism crisis and may be life-threatening. This should be carefully evaluated.
3. High blood pressure
The risk of cardiovascular accidents during or after anesthesia will be greater. The higher the blood pressure, the more dangerous it is. The blood pressure should be monitored before anesthesia.
4. High blood sugar
General anesthesia when blood sugar is too high may increase the risk of infection.
