全身麻醉不会让人变傻变笨！专家辟谣：成人大脑不受影响
中新网8月24日电 近日，网络上流传着“全身麻醉会让人变傻变笨”的说法，引发不少人的担忧。对此，中国新闻网“中新真探”栏目特别邀请专家进行辟谣，证实这一说法并不属实。
根据现有的医学研究和临床实践，全身麻醉（全麻）并不会对3岁以上人群的大脑造成伤害。通常情况下，全麻药物在体内数天甚至数小时就会被代谢完全，难以对大脑带来持续性的影响。
专家解释，全麻药物的作用机制是暂时抑制神经系统活动，使患者失去意识和感觉，从而完成手术操作。而全麻药物在进入人体后，会迅速被代谢，不会在体内长期残留。
“对于3岁以下的儿童，由于大脑发育尚未完全，全麻可能会对脑部发育造成一定影响，但对成人来说，这种影响微乎其微。”专家强调。
需要注意的是，个体差异可能会导致部分患者在麻醉后出现短暂的认知功能下降，例如记忆力减退、注意力不集中等。但这些症状通常会在麻醉药代谢完成后逐渐消失，不会对智力造成持久的影响。
专家建议，在进行手术前，患者应与医生充分沟通，了解手术风险和麻醉风险，并根据自身情况选择合适的麻醉方式。同时，患者也应保持积极乐观的心态，消除对麻醉的恐惧，有助于手术顺利进行。
总而言之，全身麻醉不会让人变傻变笨，大家不必对此过度担忧。相信随着医学技术的不断发展，麻醉技术会更加安全有效，为患者提供更加舒适的手术体验。

BEIJING, Aug. 24 (Xinhua) – Rumors circulating online claiming that general anesthesiacan lead to cognitive decline have sparked widespread concern. However, experts have debunked this myth, assuring the public that there is no evidence to support it.
According to current medical research and clinical practice, general anesthesia (GA) poses no harm to the brain for individuals aged 3 and above. Typically, GA drugs are fully metabolized within the body within days or even hours, making itunlikely to have any lasting impact on the brain.
Experts explain that GA drugs work by temporarily suppressing nervous system activity, rendering patients unconscious and insensitive, enabling surgical procedures. Upon entering the body, these drugs are quickly metabolized and do notpersist in the body for extended periods.
“While there might be some developmental impact on the brain for children under 3 due to their incomplete brain development, the effects on adults are negligible,” emphasized the experts.
It’s worth noting that individual differences may lead to temporary cognitive decline in some patients after anesthesia,such as memory impairment or difficulty concentrating. However, these symptoms usually subside after the anesthetic wears off and do not cause lasting intellectual impairment.
Experts advise patients to communicate openly with their doctors before surgery to understand the risks associated with the procedure and anesthesia, and to choose the most suitable anesthetic method based on their individual circumstances.Maintaining a positive and optimistic attitude can also help alleviate fear of anesthesia, contributing to a smoother surgical experience.
In conclusion, general anesthesia does not lead to cognitive decline, and there is no need for excessive worry. As medical technology continues to advance, anesthesia techniques will become even safer and more effective, providing patients with amore comfortable surgical experience.
