How Much Damage Does a Single General Anesthesia Cause to the Brain?

General anesthesia generally refers to the anesthesia of the entire body. There is no such statement that general anesthesia can cause significant harm to the brain in a single administration, as general anesthesia usually does not harm the brain. If there are any discomforting symptoms, it is recommended to seek medical attention promptly. General anesthesia involves the administration of anesthetics through intravenous injection, inhalation, intramuscular injection, or rectal infusion to suppress the central nervous system and achieve the effect of general anesthesia. After general anesthesia, patients will experience loss of consciousness, painlessness throughout the body, and temporarily reversible loss of memory, thereby reducing the pain of treatment and increasing the success rate of surgery. During general anesthesia, an artificial airway and ventilator-assisted ventilation are generally required to prevent cerebral hypoxia and direct damage to brain tissue. There is no such statement that general anesthesia can cause significant harm to the brain in a single administration. Fasting is required before general anesthesia to prevent food reflux and aspiration in patients during surgery, as well as complications such as coughing and choking or respiratory issues after surgery. After surgery, it is important to rest more, maintain emotional stability, and develop good sleep habits.
