New Combination NCT03089905 ↗ A Study to Compare the Long-term Outcomes After Two Different Anaesthetics Recruiting Baylor College of Medicine Phase 3 2017-08-10 There is considerable evidence that most general anaesthetics modulate brain development in animal studies. The impact is greater with longer durations of exposure and in younger animals. There is great controversy over whether or not these animal data are relevant to human clinical scenarios. The changes seen in preclinical studies are greatest with GABA agonists and NMDA antagonists such as volatile anaesthetics (eg sevoflurane), propofol, midazolam, ketamine, and nitrous oxide. There is less evidence for an effect with opioid (such as remifentanil) or with alpha 2 agonists (such as dexmedetomidine). Some, but not all, human cohort studies show an association between exposure to anaesthesia in infancy or early childhood and later changes in cognitive tests, school performance or risk of developing neurodevelopmental disorders. The evidence is weak due to possible confounding. A recent well designed cohort study (the PANDA study) comparing young children that had hernia repair to their siblings found no evidence for a difference in a range of detailed neuropsychological tests. In that study most children were exposed to up to two hours of anaesthesia. The only trial (the GAS trial) has compared children having hernia repair under regional or general anesthesia and has found no evidence for a difference in neurodevelopment when tested at two years of age. The GAS and PANDA studies confirm the animal data that short exposure is unlikely to cause any neurodevelopmental impact. The impact of longer exposures is still unknown. In humans the strongest evidence for an association between surgery and poor neurodevelopmental outcome is in infants having major surgery. However, this is also the group where confounding is most likely. The aim of our study is to see if a new combination of anaesthetic drugs results in a better long-term developmental outcome than the current standard of care for children having anaesthesia expected to last 2 hours or longer. Children will be randomised to receive either a low dose sevoflurane/remifentanil/dexmedetomidine or standard dose sevoflurane anaesthetic. They will receive a neurodevelopmental assessment at 3 years of age to assess global cognitive function.

Trial ID Title Status Sponsor Phase Start Date Summary
NCT00205712 ↗ Prevention of N-methyl-D-aspartate (NMDA) Antagonist-induced Psychosis in Kids Completed National Alliance for Research on Schizophrenia and Depression Phase 4 2003-02-01 Ketamine, an FDA approved anesthetic agent, is becoming the sedative/analgesic of choice for emergency sedation in children because it causes deep sedation with minimal respiratory depression in comparison to other available agents. However, emergence reactions are an important adverse effect of ketamine, characterized by transient changes in cognitive function, dissociation and mild schizophrenia-like symptoms. These cognitive and behavioral effects are dose-dependently induced by ketamine and other antagonists of the N-methyl-D-aspartate (NMDA) glutamate receptor. NMDA receptor hypofunction can disinhibit excitatory (cholinergic/glutamatergic) projections in key areas of the brain, and this has been proposed to explain key features of schizophrenia. Several treatments that block excessive excitatory transmitter release have also been shown to prevent cognitive and behavioral effects of ketamine-induced NMDA receptor hypofunction in humans. Alpha-2 adrenergic agonists, which can presynaptically inhibit acetylcholine release, can prevent mild ketamine-induced behavioral and cognitive symptoms in healthy human adults. However, this prevention strategy has not been evaluated in children. Children currently receive clinically-indicated treatment with the NMDA antagonist, ketamine, and this age group is an important target for pharmacological strategies aimed at the prevention of schizophrenia. This application proposes a double-blind, placebo-controlled, randomized trial to test the safety and effectiveness of dexmedetomidine, an FDA approved alpha-2 adrenergic agonist, in preventing ketamine-induced mental symptoms in children. Planned primary analyses will evaluate effects of the hypothesized prevention treatment on clinical and cognitive variables using analysis of variance (ANOVA). The proposed experiments are relevant to future prevention trials for individuals at risk for schizophrenia, and to preventing adverse effects of NMDA antagonist anesthetic agents (ketamine, nitrous oxide).
