The Department of Hernia and Abdominal Wall Surgery has been performing laparoscopic inguinal hernia capsulotomy for more than a year, and we often encounter parents who are always concerned about the need for general anesthesia for surgical procedures, thinking that the brain will be stupid after anesthesia and that it will affect the intelligence of the child. If the brain cells stop supplying oxygen for 5-8 minutes, the metabolism of the brain cells will be seriously affected and the brain function will be affected, even causing irreversible consequences. Therefore, to answer the question of whether anesthesia will affect pediatric intelligence, we must first analyze whether there will be cerebral hypoxia after anesthesia. There are four commonly used anesthesia methods: 1, basic anesthesia, which refers to preoperative sedation followed by local anesthesia or plexus anesthesia. 2, site anesthesia, including local anesthesia, lumbar anesthesia, and plexus anesthesia. These two types of anesthesia only impede the conduction of nerve fibers or nerve trunks and play a local anesthetic role, and the mind is clear during the anesthesia. Therefore, the intelligence is not affected. 3, general anesthesia, the so-called general anesthesia is the inhalation of anesthetics or intravenous injection of anesthetics, inhibit the cerebral cortex, so that the child temporarily unconscious, in the case of painless sleep to ensure the completion of various surgeries. During the process of general anesthesia, the child’s breathing is controlled by the machine, oxygen supply is guaranteed, and all vital indicators such as blood pressure and heartbeat are in the normal range, which do not affect the respiratory and circulatory functions and do not cause cerebral hypoxia. In the process of general anesthesia, although the child loses consciousness, but after the anesthesia, the child gradually wakes up and everything returns to normal, just like waking up from a sleep, and the child’s intelligence is not affected. 4.Cryogenic anesthesia, generally used for pediatric cardiovascular surgery. This anesthesia needs to block the circulation and bring down the body temperature, the respiration and circulation of the pediatric patient, and bring down the body temperature, the respiration and circulation of the pediatric patient is replaced by an artificial heart-lung machine to keep the metabolism at a minimum level. Intelligence tests were done to compare these pediatric patients before and after surgery, and it was found that there was no significant difference in IQ before and after surgery. Children who underwent surgery after anesthesia had normal memory and their academic performance did not decline, so parents’ concerns about anesthesia are unnecessary. Many parents are concerned about whether general anesthesia will have a negative impact on their child’s brain, whether it will affect intelligence and memory, etc. In fact, this concern is unnecessary. Although any medical operation is risky, the risk of general anesthesia is very low, and the risk is even lower for inhalation anesthesia, which has a fast onset and quick awakening. The anesthetic effects of general anesthesia on the brain are also short-lived, and when the anesthesia ends and the drugs are rapidly excreted, the brain’s function will return to normal. In fact, the real impact on brain function does not depend on anesthesia, but directly on whether or not cerebral hypoxia has occurred. This is because the brain is very sensitive to oxygen. However, parents do not need to worry, during the whole general anesthesia, your baby will be supplied with sufficient oxygen, there is the monitoring of blood oxygen saturation throughout the whole process, and there is also the watchful eye of modern high-tech life monitor, the doctor can always know the change of oxygen level and other vital indicators in the child’s body, to ensure that there is no hypoxia. Therefore, general anesthesia is very safe. One year after carrying out pediatric laparoscopic inguinal hernia capsulolysis, hundreds of pediatric patients treated by this procedure have been treated, and according to the postoperative follow-up survey, no anesthesia or surgical complications have occurred, and none of them have been affected by mental development due to general anesthesia.
