The potential anesthetic neurotoxicity on the neonate is an important focus of research investigation in the field of pediatric anesthesiology. It is essential to understand how these anesthetics may affect the development and growth of neonatal immature and vulnerable brains. Functional magnetic resonance imaging (fMRI) has suggested that using anesthetics result in reduced functional connectivity may consider as core sequence for the neurotoxicity and neurodegenerative changes in the developed brain. Anesthetics either directly impact the primary structures and functions of the brain or indirectly alter the hemodynamic parameters that contribute to cerebral blood flow (CBF) in neonatal patients. We hypothesis that anesthetic agents may either decrease the brain functional connectivity in neonatal patients or animals, which was observed by fMRI. This review will summarize the effect and mechanism of anesthesia on the rapid growth and development infant and neonate brain with fMRI through functional connectivity. It is possible to provide the new mechanism of neuronal injury induced by anesthetics and objective imaging evidence in animal developing brain.
新生儿潜在的麻醉神经毒性是小儿麻醉学领域研究调查的一个重要焦点。了解这些麻醉剂如何影响新生儿未成熟且脆弱大脑的发育和生长至关重要。功能磁共振成像(fMRI)表明,使用麻醉剂导致功能连接性降低可能被视为发育中大脑神经毒性和神经退行性变化的核心序列。麻醉剂要么直接影响大脑的主要结构和功能,要么间接改变有助于新生儿患者脑血流量(CBF)的血流动力学参数。我们假设麻醉剂可能会降低新生儿患者或动物的脑功能连接性,这可通过fMRI观察到。本综述将通过功能连接性总结麻醉对婴儿和新生儿快速生长发育大脑的影响及机制。这有可能提供麻醉剂诱导神经元损伤的新机制以及动物发育中大脑的客观成像证据。
