SmartTots – Perspectives from the Front Lines
Millions of children undergo surgery annually. Recent studies suggest there may be reason for concern. This video, featuring Dr. Dean Andropoulos, Dr. Peter Davis, and Dr. Caleb Ing, provides a summary as to why research is needed and the type that is needed.
SmartTots to Help Make Anesthetics and Sedatives Safer for Children
Dr. Janet Woodcock, director of the Center for Drug Evaluation and Research at the Food and Drug Administration, and Dr. Michael Roizen, of the International Anesthesia Research Society, unveil a new partnership that aims to make anesthesia safer for children.

Join SmartTots and world-renowned scientists as they discuss the up-to-the-minute findings and progress of the research – clinical, pre-clinical, in vitro, they’ll discuss it all!
Detrimental effects of general anaesthesia on young primates: are we closer to understanding the link?
The complexity of investigating a phenomenon where a direct cause-and-effect relationship may not be possible to establish cannot be overestimated. How can one with absolute certainty make a causal connection between an event in the distant past with the currently observed outcome?
General anaesthesia during infancy reduces white matter micro-organisation in developing rhesus monkeys British Journal of Anaesthesia
Non-human primates are commonly used in neuroimaging research for which general anaesthesia or sedation is typically required for data acquisition. In this analysis, the cumulative effects of exposure to ketamine, Telazol® (tiletamine and zolazepam), and the inhaled anaesthetic isoflurane on early brain development were evaluated in two independent cohorts of typically developing rhesus macaques.
A synthetic peptide rescues rat cortical neurons from anesthetic-induced cell death, perturbation of growth and synaptic assembly
Anesthetics are deemed necessary for all major surgical procedures. However, they have also been found to exert neurotoxic effects when tested on various experimental models, but the underlying mechanisms remain unknown. Earlier studies have implicated mitochondrial fragmentation as a potential target of anesthetic-induced toxicity, although clinical strategies to protect their structure and function remain sparse.
The Effects of Hesperidin on Neuronal Apoptosis and Cognitive Impairment in the Sevoflurane Anesthetized Rat are Mediated Through the PI3/Akt/PTEN and Nuclear Factor-κB (NF-κB) Signaling Pathways
Hesperidin (HPD) is a bioflavonoid found in citrus fruits. This study aimed to investigate the effects of HPD on cerebral morphology and cognitive behavior in sevoflurane anesthetized neonatal rats and the molecular mechanisms involved.
Dexmedetomidine and Clonidine Attenuate Sevoflurane-Induced Tau Phosphorylation and Cognitive Impairment in Young Mice via α-2 Adrenergic Receptor
Anesthetic sevoflurane induces tau phosphorylation and cognitive impairment in young mice. The underlying mechanism and the targeted interventions remain largely unexplored. We hypothesized that dexmedetomidine and clonidine attenuated sevoflurane-induced tau phosphorylation and cognitive impairment by acting on α-2 adrenergic receptor.
