Prospects of molecular hydrogen in perioperative neuroprotection from basic research to clinical application.
The current systematic review summarizes recent, basic clinical achievements regarding the neuroprotective effects of molecular hydrogen in distinct central nervous system conditions. ⋯ Fundamental and clinical evidence supports the antioxidant, antiinflammation, antiapoptosis and mitochondrial protective effects of hydrogen in the pathophysiology of nervous system diseases. The clinically preventive and therapeutic effects of hydrogen on different neural diseases, however, remain uncertain, and the lack of support by large randomized controlled trials has delayed its clinical application.

ReviewEducation and training in ultrasound-guided regional anaesthesia and pain medicine.
Effective and safe regional anaesthesia and pain medicine procedures require clinicians to learn and master complex theoretical knowledge and motor skills. This review aims to summarize articles relevant to education and training in these skill sets in the previous 2 years. ⋯ Research into education and training in regional anaesthesia covered multiple and diverse topics. Methodological limitations were noted in several articles, reflecting the difficulties in designing and conducting medical education studies. Nonetheless, the evidence-base continues to mature and innovations provide exciting future possibilities.

ReviewPostoperative delirium: why, what, and how to confront it at your institution.
The current article reviews the importance of postoperative delirium (POD), focusing on the older surgical population, and summarizes the best-practice guidelines about POD prevention and treatment which have been published within the last several years. We also describe our local experience with implementing a perioperative delirium risk stratification and prevention pathway, and review implementation science principles which others may find useful as they move toward risk stratification and prevention in their own institutions. ⋯ POD continues to be a serious perioperative complication commonly experienced by older adults. Growing appreciation of its prognostic implications and evidence behind multidisciplinary, collaborative, and focused prevention strategies rooted in implementation science have prompted several major groups to issue consensus guidelines. Adopting best practices POD risk stratification and prevention pathways will improve perioperative care for older adults.

ReviewDouble standard: why electrocardiogram is standard care while electroencephalogram is not?
A compelling argument that the EEG and it's derivative monitors should be 'standard of care' during anaesthesia, contrasting this with the ECG, arguably a less useful, actionable or meaningful monitor, yet has been widely considered a routine monitor for three decades.
The authors' main thesis is that:
- Intraoperative EEG accurately monitors anaesthetic depth.
- Using EEG to guide intraoperative depth may reduce both anaesthetic use and postoperative delirium.
- Reducing drug exposure and depth of anaesthesia probably has significant patient and societal benefits.
- All anaesthetists and anesthesiologists should be familiar with interpreting the raw EEG in the context of anaesthesia.
However...
- While postoperative delirium is common in the over 65y age group (15-20%) and is associated with adverse outcomes, it is less clear that avoiding excessive depth reliably reduces postoperative delirium (some studies say yes, others...)
- Additionally, because post-op delirium is often used as (or at least inadvertently becomes) a surrogate marker for a range of adverse post-op events, then it follows that EEG monitoring should also be associated with reducing these events. This has not yet been shown.
