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.

Pediatric Anesthesia Questions and Myths-Mayo Clinic

Dr. Randall Flick at Mayo Clinic “debunks myths” and answers common questions raised by parents in regard to anesthesia.

False Interpretation of Scientific Data Leads to Biased Conclusions About the Association Between Cesarean Deliveries Under General Anesthesia and Risk of Autism Spectrum Disorder.

In their recent letter to the editor, Sagi-Dain et al. severely criticized our recent study entitled “Exposure to general anesthesia may contribute to the association between cesarean delivery and autism spectrum disorder” by Huberman et al. Here, we respond point-by-point to their criticism, clarify several false statements and interpretations, and explain the importance and validity of our study.

Exposure to General Anesthesia May Contribute to the Association between Cesarean Delivery and Autism Spectrum Disorder.

Cesarean section (CS) has been consistently associated with susceptibility to autism spectrum disorder (ASD), however, the underlying mechanism for this association remains vague. Here, we studied various pre-peri-and-neonatal factors among 347 children with ASD, 117 children with other developmental delays (DD), and 2226 age, sex and ethnicity matched controls.

Effects of Xenon-Based Anesthetic Exposure on the Expression Levels of Polysialic Acid Neural Cell Adhesion Molecule (PSA-NCAM) on Human Neural Stem Cell-Derived Neurons.

Numerous studies suggest a long duration of anesthesia during the late gestation period and infancy is associated with an increased risk of neuronal damage and neurocognitive impairment. The noble gas xenon is an anesthetic that is reported to have neuroprotective effects in some circumstances at certain concentrations. Currently, the effects of xenon on the brain and its potential neuroprotective properties, and/or the effects of xenon used in combination with other anesthetics, are not clearly understood and some reported data appear contradictory.

Downregulation of CDK5 Restores Sevoflurane-Induced Cognitive Dysfunction by Promoting SIRT1-Mediated Autophagy.

An increasing number of studies have found that use of traditional anesthetics may lead to cognitive impairment of the immature brain. Our previous studies verified that cyclin-dependent kinase 5 (CDK5) plays a role in sevoflurane-induced cognitive dysfunction. Autophagy was shown to protect against anesthesia-induced nerve injury. Therefore, the current study aimed to ascertain if autophagy participates in anesthesia-induced neurotoxicity.

Desflurane and Surgery Exposure During Pregnancy Decrease Synaptic Integrity and Induce Functional Deficits in Juvenile Offspring Mice.

Anesthesia in pregnant women may cause adverse effects in the hippocampus of unborn babies and fetal brain development. The mechanisms underlying pathological changes resulting from anesthetics are unclear. This study tested the hypothesis that exposure to desflurane during pregnancy may impair cognition and memory functions of juvenile offspring.

Ketamine exerts neurotoxic effects on the offspring of pregnant rats via the Wnt/β-catenin pathway.

Ketamine is an anesthetic and analgesic drug widely used in clinical anesthesia. To ensure the safety of anesthesia, it is necessary to study its side effects. Pregnancy is a key period for the development and growth of offspring. During this period, the proliferation and differentiation of brain cells and the synaptic formation are easily affected by external stimuli.
