As a pediatric anesthesiologist, one of the questions I often encounter is, “Will my child become stupid after using general anesthesia?” Yes, for a long time, there has been a saying circulating in the society that children will become dumb and stupid after using general anesthesia, which will affect learning and development. In fact, this statement is not scientific. Children often cry and are uncooperative when doing surgery because of their long-term dependence on their parents and their fear of surgery, anesthesia, and medical personnel, so general anesthesia is needed during surgery. General anesthesia means that children are temporarily unconscious after using general anesthetics, and they can complete various surgeries without pain and in quiet sleep. According to current medical data, there is no evidence that the currently used anesthetic drugs and methods are harmful to the health and intelligence of children. All general anesthetic drugs are temporary and reversible, and after a certain period of time in the body, they are gradually detoxified by the liver to reduce metabolism, partly by the respiratory tract, digestive tract, urinary tract out of the body, and the child gradually wakes up. Parents are reminded not to mistake the slow response of children during the postoperative recovery period for the effect of anesthetics on intelligence. Because of the low metabolic rate and poor excretory function of children, coupled with the “secondary distribution” of anesthetic drugs stored in fat, muscle and other tissues in the blood after surgery, children still have some residual anesthetic in their blood, which shows indifferent expression and slow reaction during the postoperative recovery period. This phenomenon is a normal metabolic process of anesthetic drugs and should not be a cause for concern. Therefore, we say that the anesthetic drug only temporarily acts on the child’s nerves, and the nervous system function will return to normal after the anesthesia. Intelligence is closely linked to brain activity. The activity of human brain cells is closely related to the amount of oxygen, and it is poorly tolerant to oxygen deprivation, and a general interruption of brain oxygen supply for 5 to 8 minutes can cause irreparable damage. If the airway is kept open during anesthesia to ensure the oxygen supply to the child, the brain cells will carry out normal metabolism as usual and the intelligence of the child will not be affected. Some people may say, “So-and-so child became stupid because of surgical anesthesia.” In this case, we have to make a specific analysis. As already mentioned, human brain cell activity is closely related to oxygen. In anesthesia or surgery, cerebral hypoxia can occur suddenly due to vomiting, blockage of the airway by the back of the tongue, laryngeal spasm leading to asphyxia, etc. Cerebral hypoxia can also occur during cardiac arrest, hemorrhage, and hemorrhagic shock, and without timely resuscitation, it can cause adverse consequences. These are all possible accidents in anesthesia, and cannot be simply considered as caused by the use of anesthetic drugs. Medical theory and domestic and foreign practice have long proved that general anesthesia does not affect the intelligence of children if no accidents occur; the accident rate of foreign surgery is only a few tens of thousands, even less than the death rate of traffic accidents in large cities. Although anesthesia has no effect on pediatric intelligence, but any anesthesia surgery is a certain risk exists, pediatric anesthesia surgery on the anesthesiologist, the surgeon’s technical requirements are more stringent, any pediatric is not a shrinking adult, so parents in the choice of hospital must choose a more professional women and children’s hospital for surgery, because respiratory infections, colds, etc. on pediatric anesthesia risk is quite large, elective A few days before the surgery, pay attention to the child to keep warm, do not let the child catch a cold and flu, increasing the risk in surgical anesthesia.
