When babies need surgery, many parents feel ambivalent about anesthesia—hoping it eases their child's pain yet worrying it might affect brain development. This stems from common misconceptions about anesthesia.
Misconception 1: Anesthesia impairs intelligence—avoid surgery if possible
The physical damage and psychological distress caused by a child's illness can already lead to lower cognitive abilities before surgery. So, does anesthesia actually affect a child's intellectual development? The answer is no. Numerous domestic and international studies have shown that any impact on cognitive development is related to the child's underlying illness, not the anesthesia itself.
The period before age 3 is a critical stage for brain development. Experts note that repeated or prolonged use of general anesthesia or sedatives in children under 3 may potentially affect brain development. When surgery exceeds 3 hours or involves multiple procedures for children under 3, the risks and benefits of surgery should be carefully weighed.
Therefore, only major surgeries lasting over 3 hours or repeated surgical anesthesia may potentially cause effects, and even then, the impact is limited.Thus, when anesthesia is necessary, it should be chosen as the lesser of two evils. Regardless of whether anesthesia affects a child's learning or memory abilities, surgery should proceed under anesthesia when it is life-saving.
For brief, single-session general anesthesia during minor procedures, there is no impact on the child's attention span, cognitive abilities, reading skills, observational skills, or computational abilities.
Misconception 2: Surgery is necessary, so avoid anesthesia if possible. A child's fear of surgery can cause long-term psychological harm. The physiological reactions triggered by surgical pain, along with negative memories of that pain, can disrupt the child's daily life. These painful experiences and memories may persist throughout life, potentially leading to psychological issues such as attention deficits.
Anesthesia is becoming a key component of comfort-oriented healthcare, particularly for uncooperative children. It significantly reduces discomfort during examinations, lowers the risk of injury during procedures, greatly diminishes psychological fear, and enhances patient comfort and compliance with regular follow-ups.
Misconception 3: If anesthesia is necessary, choose local over general anesthesia. Local anesthesia requires the child to remain awake and cooperative during the procedure. Nearly 100% of children cannot achieve this level of cooperation, causing anesthesia risks to skyrocket. In comparison, general anesthesia is the optimal choice.
Misconception 4: Eating a little before anesthesia is okay. Children are not miniature adults. Due to their unique anatomical and physiological characteristics, pediatric anesthesia-related mortality rates are significantly higher than in adults. It is absolutely essential that children not eat or drink anything for 6 to 8 hours before surgery.
This is because children's stomachs function very differently from adults'. A child's stomach lies horizontally in their abdomen. While adults have a higher stomach entrance than exit, a child's are nearly level.The adult stomach's entrance closes tightly, but the child's entrance does not seal properly. Additionally, children have smaller stomachs. Eating too much or consuming greasy foods makes digestion difficult and increases the risk of reflux. Refluxed food can enter the child's windpipe, easily blocking it and causing suffocation—a highly dangerous situation.
Therefore, for your child's safety, ensure they eat lightly and in small portions the day before surgery, and strictly observe preoperative fasting. Parents need not worry about their child going hungry—necessary fluids and nutritional support will be provided during the procedure.
Finally, a reminder to parents: Children, as a special group, often struggle to communicate effectively with medical staff.Therefore, before anesthesia, parents should actively cooperate with doctors. Do not conceal medical history, drug allergies, or special conditions. Adhere to the preoperative fasting and fluid restriction, and cooperate fully with the anesthesiologist's care. This will ensure a safe and smooth passage through the anesthesia period.
