Prolonged exposure to ketamine increases neurodegeneration in the developing monkey brain
Abstract
Ketamine, a widely used pediatric anesthetic, has been associated with enhanced neuronal toxicity in the developing brain, but mechanisms and neuronal susceptibility to neurotoxic insult leading to neuronal cell death remain poorly defined. One of the main goals of this study was to determine whether there is a duration of ketamine‐induced anesthesia below which no significant ketamine‐induced neurodegeneration can be detected. Newborn rhesus monkeys (postnatal day 5 or 6) were administered ketamine intravenously for 3, 9 or 24 h to maintain a steady anesthetic plane, followed by a 6‐h withdrawal period. The 9‐ and 24‐h durations were selected as relatively long and extremely long exposures, respectively, while the 3‐h treatment more closely approximates a typical duration of pediatric general anesthesia. Animals were subsequently perfused under anesthesia and brain tissue was processed for analyses using silver and Fluoro‐Jade C stains and caspase‐3 immunostain. The results indicated that no significant neurotoxic effects occurred if the anesthesia duration was 3 h. However, ketamine infusions for either 9 or 24 h significantly increased neuronal cell death in layers II and III of the frontal cortex. Although a few caspase‐3‐ and Fluoro‐Jade C‐positive neuronal profiles were observed in some additional brain areas including the hippocampus, thalamus, striatum and amygdala, no significant differences were detected between ketamine‐treated and control monkeys in these areas after 3, 9 or 24 h of exposure. These data show that treatment with ketamine up to 3 h is without adverse effects as determined by nerve cell death. However, anesthetic durations of 9 h or greater are associated with significant brain cell death in the frontal cortex. Thus, the threshold duration below which no neurotoxicity would be expected is somewhere between 3 and 9 h.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
