On April 16 and 17, 2016, the Fifth biennial Pediatric Anesthesia & Neurodevelopment Assessment (PANDA) symposium was convened at the Morgan Stanley Children's Hospital of New York at Columbia University Medical Center. During the symposium, experts in the fields of anesthesiology, neuropsychology, and epidemiology were convened in a small group session to determine the level of confidence in the current clinical evidence and the next steps in anesthetic neurotoxicity clinical research. ⋯ It was, however, recognized that the continuum of data that is seen in studies of other toxic environmental exposures, such as lead poisoning, has not been established in the anesthetic neurotoxicity literature, specifically regarding the timing of the exposure, the dose effects, contributing perioperative conditions, or vulnerable populations. As a result, these questions may need to be addressed in observational studies to guide future clinical trials.

Neurotoxicity related to early exposure to various insults, both anesthesia-related and nonanesthesia-related, is a topic of ongoing and increasing interest. To better understand the process by which this might occur, the fifth PANDA Symposium convened a session in which 4 notable neuroscientists discussed current concepts and research in neurodevelopment, highlighting periods of particular susceptibility and ways in which neural connectivity and systemic functioning may be affected.

ReviewMolecular Mechanisms of Anesthetic Neurotoxicity: A Review of the Current Literature.
Data from epidemiologic studies and animal models have raised a concern that exposure to anesthetic agents during early postnatal life may cause lasting impairments in cognitive function. It is hypothesized that this is due to disruptions in brain development, but the mechanism underlying this toxic effect remains unknown. ⋯ The level of evidence for each putative mechanism is critically evaluated, and we attempt to draw connections between them where it is possible to do so. Although there are many promising avenues of research, at this time no consensus can be reached as to a definitive mechanism of injury.
