What does general anesthesia body “experience”? Does general anesthesia hurt memory?

General anesthesia is referred to as general anesthesia, which refers to the temporary inhibition of central nervous system function by anesthetics injected into human body through muscle or vein injection and respiratory tract inhalation. The clinical manifestations are general pain loss, lost mind, forgetfulness, skeletal muscle relaxation and reflex inhibition. The concentration of drugs in blood directly determines the degree of inhibition on the central nervous system. Therefore, the inhibition degree of central nervous system can be controlled by adjusting the concentration of anesthetics. And this inhibition is completely reversible, when the drug is metabolized or discharged from the body, the patient’s mind and various reflections will be gradually recovered. What is the body going through when it comes to general anesthesia? Can memory in the brain be hurt? And so on, through the introduction below, may eliminate some of the confusion.
1、 What is the body going through during general anesthesia?

  1. Induction period
    According to the different operation time and the patient’s physical condition, doctors will choose to give general anesthesia to the patients by intravenous anesthesia or by the combination of intravenous anesthesia and oxygen mask inhalation anaesthetic. Then the patient will gradually become sleepy and the respiratory rate will slow down until the brain is completely unconscious. Because the brain is unconscious at this time, it may cause the patient to stop breathing, so the ventilator will be used in the operating room to help the patient maintain the breath.
  2. Maintenance period
    The anesthesia agent that doctors give patients in induction period can only be maintained for a short period of time. Therefore, during the operation, anesthesiologist will continue to supplement the anesthetics to patients by injection pump, so as to maintain the patients in anesthesia state during the whole operation, and no discomfort will be generated.
  3. Recovery period
    When the operation is near the end, the doctor will gradually reduce the amount of anesthetics used to the patient, so that the consciousness of the patient can be gradually restored, blood pressure and heart rate will gradually return to normal until the body can recover and maintain the breath independently.
    2、 After general anesthesia, will memory be hurt?
    General anesthesia generally does not harm the memory of the patients, but when some patients wake up after general anesthesia, they will have temporary memory loss. Memory is like a variety of levels in the brain, and when all general anesthesia drugs enter, all levels of the brain are closed. After waking up, these levels are gradually opened in a certain order, some of them are delayed to open, so some patients have the phenomenon of not knowing people after operation, even talking nonsense, in fact, it is the reason that some levels of brain caused by anesthesia have not been opened.
    From heart bypass to tooth extraction, people may experience an anesthesia operation in their life. When general anesthesia is carried out, the human body will experience three stages: induction period, maintenance period and recovery stage. After general anesthesia, memory will not be damaged, so you can not worry about general anesthesia.
