| 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. |

All Clinical Trials for Dexmedetomidine

| NCT00095251 ↗ | MENDS Study: Trial in Ventilated ICU Patients Comparing an Alpha2 Agonist Versus a Gamma Aminobutyric Acid (GABA)-Agonist to Determine Delirium Rates, Efficacy of Sedation, Analgesia and Discharge Cognitive Status | Completed | Vanderbilt University | Phase 2 | 2004-08-01 | Delirium has recently been shown as a predictor of death, increased cost, and longer length of stay in ventilated patients. Sedative and analgesic medications relieve anxiety and pain, but may contribute to patients' transitioning into delirium. It is possible that modifying the paradigm for sedation using novel therapies targeted at different receptors, such as dexmedetomidine targeting alpha2 receptors and sparing the GABA receptors, could provide efficacious sedation yet reduce the development, duration, and severity of acute brain dysfunction (delirium). |

| NCT00142493 ↗ | Effect of Affective Content on Drug Induced Amnesia of Episodic Memory | Completed | Memorial Sloan Kettering Cancer Center | Phase 1 | 2004-09-01 | The purpose of this research is to understand how some of the drugs commonly used in anesthesia impair memory. We are particularly interested in whether the emotion associated with a memory influences how well these drugs are able to block memory. We are studying four commonly used drugs-propofol, thiopental, midazolam, and dexmedetomidine, all of which may have slightly differing effects. We will also study an inactive substance, called a placebo, that should have no effect. The results of this study will provide information that will be useful in understanding how memory works, how these drugs affect memory, and possibly why some people don't have their memory blocked as easily as others. |
