When doing surgical operations, general anesthesia is often required, and many parents will have all kinds of worries about whether it is safe and whether it will have an impact on the child’s growth and development, intelligence and so on, so will general anesthesia surgery make the child stupid? “Doctor, can we use local anesthesia? Will general anesthesia numb the child silly?” Almost all parents will be in the child into the operating room before the implementation of general anesthesia for children to show concern. Children’s surgery more than 95% of the need for general anesthesia is difficult for children to cooperate with the operation, for example, some operations need to maintain the same position for a long time, the children are difficult to tolerate the discomfort. Secondly, out of fear of the unfamiliar environment in the operation or the operation itself, children will cry more than, which is also not conducive to the operation. In the past, local anesthesia could be used for some of the more cooperative and older children, but the surgery will leave a memory of fear in the child, which may leave a shadow in the child’s psyche as he or she grows older. Anesthesia will not make the child become stupid proposed surgery children into the operating room, the anesthesiologist will immediately give anesthesia drugs through the vein to let them fall asleep quickly, and then according to the needs of the operation to give the child regional nerve block anesthesia, or give intravenous inhalation compound anesthesia. Regional nerve block anesthesia is a medication that is injected into the spinal cord, nerve trunks, or around nerve endings so that the pain sensation cannot be transmitted to the brain and the pain is relieved. These medications do not work in the brain, so they do not directly affect intelligence. General anesthetics are injected or breathed into the bloodstream by the lungs and play a role, the effect on the brain is transient, that is, to reach a certain concentration of blood to produce pain relief, but through the metabolism and transformation, the concentration in the blood gradually decreases, the drug is metabolized out of the child will be awake and return to normal. The activity of human brain cells is closely related to the amount of oxygen carried by the blood, and its tolerance to oxygen deprivation is very poor. Generally, interrupting the oxygen supply to the brain for 5-8 minutes will cause irreparable damage. During anesthesia or surgery, cerebral hypoxia may occur due to vomiting and aspiration, tongue drop blocking the airway, and asphyxia due to laryngospasm. In addition, cerebral hypoxia can also occur during surgery due to cardiac arrest, hemorrhage, toxic shock, etc., which can lead to adverse consequences if not rescued in time. Therefore, parents cannot simply think that all the adverse effects on brain cells are caused by anesthesia. Some children in the postoperative anesthesia awake process may experience a period of agitation, different children have different performance, for example, some children show irritability, restlessness, love to cry, serious and even have a transient memory, cognitive dysfunction, parents must not be postoperative recovery during the children’s slow response to be mistaken for anesthesia on the impact of intelligence. Because of the low metabolic rate of children, poor excretory function, coupled with the storage of anesthesia drugs in fat, muscle and other tissues in the operation of the secondary distribution of anesthetics in the blood after the operation, children still have a certain amount of residual anesthetics in the blood or due to some of the anesthetics metabolites produced by the side effects of the child showed postoperative recovery period of indifference to the expression of the children, unresponsive. This phenomenon is a normal reaction during the metabolism of anesthesia drugs, parents do not need to worry too much, usually within a day these symptoms will disappear. Preoperative anesthesia with children to visit the anesthesia clinic anesthesia is like a plane ride, the plane before takeoff to carry out a detailed “physical examination”, the child anesthesia before the same to ensure that the organism is in a better state, parents may wish to take their children to the hospital to see the anesthesia clinic. Generally speaking, before the operation, the child can not catch a cold, diarrhea, vital signs to meet the standards of normal children, exclude cardiovascular, respiratory, blood system of serious diseases, correct anemia. This will ensure the safety and smoothness of the child’s anesthetic flight for this surgery. However, if it is an emergency surgery is another matter, to save the life of the main, then the child’s family should be with the doctor to face the risk and the courage to bear.
