Parents are already worried about having surgery on their child’s eyes… surgery on the eyes, it’s scary! And the doctor said there is also anesthesia, which is even more scary, will it affect the child’s intelligence? Ophthalmic surgery for children mostly uses general anesthesia, and many parents are worried about whether general anesthesia will have a negative impact on the child’s brain, whether it will affect intelligence, memory, etc. In fact, this worry is unnecessary. Although any medical operation has risk, the risk of general anesthesia is very low, and the inhalation anesthesia drugs currently used for children are fast-acting, quick to wake up, and metabolized quickly in the body, which is safer if the child’s liver and kidney function is normal. The effect of general anesthesia on the brain is also short-lived, and when the anesthesia is over and the drug is rapidly excreted, the brain function will be completely restored to normal. In fact, the real impact on brain function does not depend on the anesthesia, but directly on whether brain hypoxia occurs. Because the brain is very sensitive to oxygen, but throughout the process of general anesthesia, the child will receive an adequate supply of oxygen, there is the whole process of blood oxygen saturation monitoring, and at the same time there is a modern high-tech life monitor to look after, the anesthesiologist can always understand the changes in the oxygen level and other vital indicators in the child’s body, to ensure that no hypoxia will occur. Of course, parents should also pay attention to the following: before the anesthesia must be fasted for more than 6 hours, must improve the relevant blood and electrocardiogram, imaging examination, a week before the operation can not have a cold and fever, etc., the child’s safety depends on us together to ensure.
