Key result
Current clinical evidence suggests minimal or nonexistent long-term neurodevelopmental risk associated with a single anesthesia exposure in healthy infants and children.
Why the study?
Growing research suggests sedative drugs and anesthetic agents may have long-lasting detrimental neurocognitive effects in children, prompting concern from parents and regulatory agencies.
Does general anesthesia and sedative drug exposure cause long-lasting detrimental neurocognitive effects in infants and children?
Does general anesthesia and sedative drug exposure cause long-lasting detrimental neurocognitive effects in infants and children?
Despite animal models demonstrating neuroapoptosis, clinical evidence indicates that a single, short exposure to general anesthesia does not significantly impair long-term neurocognitive development in healthy children.
Single short exposures appear low-risk in healthy children; leaves open cumulative effects of repeated or prolonged anesthesia.
The clinical pediatric anesthesiology community has been greatly affected by a growing body of research suggesting that sedative drugs and anesthetic agents may have long lasting detrimental neurocognitive effects in children. Various animal models have indicated apoptotic brain cell death and neurocognitive impairment following anesthetic exposure in early life. Although these studies cannot be directly extrapolated to anesthesia in children, parents and governmental regulatory agencies have been paying attention nonetheless. Adding to the evidence are a number of human epidemiologic studies that have documented neurologic deficits and cognitive decline following early anesthetic exposure. 1-4 Clinical studies in children exposed to general anesthesia have assessed outcome measures including academic performance or school readiness, validated neuropsychologic testing, and educational interventions for neurodevelopmental or behavioral problems.

Irim Salik (2022) conducted a review in Anesthetic neurotoxicity. General anesthesia vs. Unexposed or regional anesthesia was evaluated on Neurocognitive and developmental outcomes. Current clinical evidence suggests minimal or nonexistent long-term neurodevelopmental risk associated with a single anesthesia exposure in healthy infants and children.
