Many eye surgeries in children are performed under general anesthesia, so it is fair to say that anesthesia is closely related to the work of our pediatric ophthalmologists. Whenever we explain the surgery to parents, we are always asked, “Is anesthesia dangerous?” “Will this anesthesia affect the child’s brain and will the IQ drop in the future?” The following is a brief introduction to the current anesthesia methods commonly used in children’s hospitals to allay parents’ preoperative concerns. The first step in anesthesia is to put a mask on the baby, who will smell an anesthetic gas with a scent. This anesthetic, called sevoflurane, is known as a landmark drug for inhalation anesthesia and is used for general anesthesia in children safely and without pain. The baby gradually drifts off to sleep and does not feel anything. At this point, the anesthesiologist will establish intravenous access and intubate the baby to ensure that the baby has enough oxygen throughout the procedure. The first step of anesthesia induction is complete and the baby will not have a horrible, painful struggle. Next, the ophthalmologist will maintain the baby in a drowsy anesthetic state with medication while the ophthalmologist performs the procedure. During the entire procedure, the baby’s circulation, breathing, oxygen level in the blood, etc. are closely monitored and very safe. At the end of the procedure, the anesthesiologist stops administering the medication and the child goes through the process of awakening from the anesthesia. This anesthesia is administered by inhalation and the drug is metabolized quickly. The baby will wake up from the anesthesia soon after the drug is stopped. So many parents are worried about the question, will the anesthesia we use damage the baby’s brain? The answer is clear: the anesthetic drugs currently used do not affect brain development. The risk of anesthesia is that if hypoxia occurs during surgery, it will cause damage to the brain’s nervous system, because the human brain is very sensitive to the need for oxygen, especially in children, and continuous hypoxia may produce some irreversible damage. In fact, nowadays, anesthesia techniques are very well developed, and the whole process is closely monitored, so the possibility of such anesthesia accidents is minimal. What parents need to pay attention to is that they must fast their children before the operation as required, otherwise the accidental aspiration caused by the child vomiting during anesthesia is also very dangerous. We hope that parents will have a scientific understanding of anesthesia and not delay their child’s surgery because of fear of anesthesia.
