ReviewRegional anesthesia global health collaborations- a scoping review of current intervention methods.
Perioperative anesthesia-related mortality is significantly higher in low-resource compared to high-resource countries. Regional anesthesia techniques can provide safety, cost, and access benefits when compared to general anesthesia in these settings but is underutilized primarily due to a lack of experienced educators and training opportunities. Academic institutions and international organizations are attempting to fill this educational gap through collaborations, but these efforts need examination for best practices going forward. ⋯ Robust reports on international collaborations providing capacity enhancing educational interventions in regional anesthesia have increased in recent years but are still rare and should be encouraged going forward. Short courses supported by high-resource countries can be effective in low-resource areas when partnerships produce curricula that are well designed.

ReviewUse of regional analgesia to prevent the conversion from acute to chronic pain.
Chronic post-surgical pain (CPSP) prevalence has not changed over the past decades what questions the efficacy of preventive strategies. Regional analgesia is used to control acute pain, but preventive effect on CPSP remains debated. Failures and future application of regional analgesia to prevent transition from acute to chronic pain will be discussed. ⋯ Regional analgesia failure to prevent CPSP development should prompt us to reconsider its perioperative utilization. Patients' stratification, for example high-pain responders, might help to target those who will most benefit of regional analgesia. The impact of regional analgesia on secondary pain-related outcomes such as intensity and neuropathic character despite no difference on CPSP incidence requires more studies. Finally, the preventive effect of regional analgesia targeted interventions on CPSP in patients suffering from severe subacute pain deserves to be assessed.

Observational StudyKetamine Associated Intraoperative Electroencephalographic Signatures of Elderly Patients With and Without Preoperative Cognitive Impairment.
Ketamine is typically used by anesthesiologists as an adjunct for general anesthesia and as a nonopioid analgesic. It has been explored for prevention of postoperative delirium, although results have been contradictory. In this study, we investigated the association of ketamine with postoperative delirium and specific encephalographic signatures. Furthermore, we examined these associations in the context of baseline neurocognition as measured by a validated assessment. ⋯ Ketamine-related changes in EEG are observed in a heterogeneous group of patients receiving spine surgery. This result was driven primarily by the effect of ketamine on cognitively normal patients and not observed in patients that were cognitively impaired at baseline. Furthermore, patients who were cognitively impaired at baseline and who had received ketamine were more likely to develop postoperative delirium, suggesting that cognitive vulnerability might be predicted by the lack of a neurophysiologic response to ketamine.

Meta AnalysisProphylactic Postoperative Noninvasive Ventilation in Adults Undergoing Upper Abdominal Surgery: A Systematic Review and Meta-Analysis.
Postoperative pulmonary complications (PPCs) are a leading cause of morbidity and mortality following upper abdominal surgery. Applying either noninvasive ventilation (NIV) or continuous positive airway pressure (CPAP) in the early postoperative period is suggested to prevent PPC. We aimed to assess whether postoperative NIV or CPAP or both prevent PPCs compared with standard care in adults undergoing upper abdominal surgery, including in those identified at higher PPC risk. Additionally, the different interventions used were evaluated to assess whether there is a superior approach. ⋯ These findings suggest routine provision of either prophylactic NIV or CPAP following upper abdominal surgery may not be effective to reduce PPCs' including in those identified at higher risk.

ReviewHyperlactatemia and other perioperative metabolic disturbances in neuroanesthesia.
The concept of 'brain-body cross-talking' has gained growing interest in the last years. The understanding of the metabolic disturbances (e.g., hypernatraemia/hyponatraemia and hyperlactatemia) in neurosurgical patients has improved during the last years. ⋯ These findings will contribute to a better understanding of the pathophysiology involved and enable better prevention and therapy where possible in clinical practice.
