To figure out whether general anesthesia will affect intelligence, first of all, we must talk about brain cell activity from a healthy person, brain cell activity requires sufficient oxygen and glycogen, if the respiratory and circulatory dysfunction, brain cells will be hypoxic, when the lack of oxygen for 5-8 minutes, brain cells will swell and degeneration, or even death, this damage is irreversible, will make a great impact on intelligence or even become stupid. In contrast, anesthetic drugs enter the body through veins and inhalation, and only play a transient inhibitory effect on the human nervous system, and generally do not affect respiratory and circulatory functions, much less cause cerebral hypoxia. Although the patient will temporarily lose consciousness during anesthesia, he or she will be awake immediately after the anesthesia, just like sleeping for a while, and there will be no effect on intelligence. In order to prevent the anesthesia from being too deep and inhibiting breathing, which leads to cerebral hypoxia, anesthesiologists will closely monitor and constantly adjust the depth of anesthesia, and cooperate with oxygen absorption, so that the patient’s depth of anesthesia is always maintained at a level that is conducive to surgery and does not cause cerebral hypoxia. Nowadays, the level of anesthesia and intraoperative monitoring is so high that there has been no anesthesia accident since the establishment of our hospital. In addition, for common pediatric diseases such as hernia, syringomyelia and appendicitis, the operation time is very short and the amount of anesthesia used is very small, so under normal circumstances anesthesia will not have any effect on the child’s intelligence, and the child will not become stupid after anesthesia! So the family has absolutely nothing to worry about.
