The safety of anaesthesia has improved as a result of better control of anaesthetic depth. However, conventional monitoring does not inform on the nature of nociceptive processes during unconsciousness. A means of inferring the quality of potentially painful experiences could derive from analysis of brain activity using neuroimaging. We have evaluated the dose effects of remifentanil on brain response to noxious stimuli during deep sedation and spontaneous breathing. ⋯ The response to moderately intense focal pressure in pain-related brain networks is effectively eliminated with safe remifentanil doses. However, the safety margin in deep sedation-analgesia would be narrowed in minimising not only nociceptive responses, but also arousal-related biological stress.

The clinical actions of sugammadex have been well studied, but the detailed molecular mechanism of the drug encapsulation process has not been systematically documented. The hypothesis was that sugammadex would attract rocuronium and vecuronium via interaction with the sugammadex side-chain "tentacles," as previously suggested. ⋯ Computational simulations demonstrate the dynamics of neuromuscular blocking drug encapsulation by sugammadex occurring from the opposite direction to that hypothesized and also how high concentrations of unbound sugammadex can potentially weakly bind to other drugs given during general anesthesia.

Aim To compare the outcome of sole dexmedetomidine or with other sedative drugs in paediatric patients during magnetic resonance imaging (MRI). Methods Literature was obtained from PubMed and ScienceDirect from 2010-2020 using key words: sedation, paediatric, dexmedetomidine, ambulatory, MRI, ketamine, propofol, midazolam. The literature selection was based on Participant, Intervention, Comparators, Outcomes (PICO) analysis. ⋯ Intranasal dexmedetomidine is more recommended than its combination with midazolam. Combining dexmedetomidine with ketamine, propofol or midazolam provides a shorter recovery time. Conclusion A combination of dexmedetomidine with other sedatives such as ketamine, propofol and midazolam is better than sole dexmedetomidine for paediatric sedation during magnetic resonance imaging.
