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.
Maternal surgery during pregnancy has a transient adverse effect on the developing fetal rabbit brain
Recently, the US Food and Drug Administration called for cautious use of anesthetic drugs during pregnancy. In 0.2−2% of pregnancies, nonobstetric surgery is being performed. The consequences of anesthesia during pregnancy on fetal development remain unclear, and preclinical studies in relevant animal models may help to elucidate them.
Ketamine is widely used in infants and young children for anesthesia, and subanesthetic doses of ketamine make neurons form new protrusions and promote synapse formation. However, the precise pathological mechanisms remain to be elucidated. In this study, we demonstrated that ketamine administration significantly increased dendritic spine density and maturity in rat cortical neurons in vivo and in vitro.
Hypoxia, hypercarbia, and mortality reporting in studies of anaesthesia-related neonatal neurodevelopmental delay in rodent models: A systematic review.
The concept of anaesthesia-related neonatal neurotoxicity originated in neonatal rodent models, yet prospective clinical studies have largely not supported this concern.
We aimed to evaluate the neurotoxicity and mechanisms of anesthetics propofol in hESC-derived neurons. Cell apoptosis in hESC-derived neurons’ exposure to 4, 10 and 20 μg/mL propofol for 6 h was assessed using terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate in situ nick end labeling (TUNEL) staining and microRNA-665 (miR-665) expression was assessed using quantitative reverse transcription polymerase chain reaction (qRT-PCR).
Cognitive impairment and transcriptomic profile in hippocampus of young mice after multiple neonatal exposures to sevoflurane.
Children with repeated inhalational anesthesia may develop cognitive disorders. This study aimed to investigate the transcriptome-wide response of hippocampus in young mice that had been exposed to multiple sevoflurane in the neonatal period.
Dexmedetomidine pretreatment attenuates isoflurane-induced neurotoxicity via inhibiting the TLR2/NF-κB signaling pathway in neonatal rats
Isoflurane is a commonly used inhalational anesthetic that can induce neurotoxicity, while Dexmedetomidine (Dex) has significant neuroprotective effects. In our study, we explored the effects of Dex on isoflurane-induced neurotoxicity through the TLR2/NF-κB signaling pathway.
