A number of functional magnetic resonance imaging (fMRI) studies rely on application of anesthetic agents during scanning that can modulate and complicate interpretation of the measured hemodynamic blood oxygenation level-dependent (BOLD) response. The purpose of the present study was to investigate the effect of general anesthesia on two main components of BOLD signal including neuronal activity and vascular response. ⋯ This experiment for the first human study showed that anesthesia may play an important role in dissociation between neuronal and vascular responses contributed to hemodynamic BOLD signal using BH fMRI imaging that may assist the implication of general anesthesia and interpretation of outcomes in clinical setting.

Meta AnalysisUsefulness of Analgesia Nociception Index for guiding intraoperative opioid administration: a systematic review and meta-analysis.
This study primarily aimed at investigating the efficacy of Analgesia Nociception Index (ANI) for guiding intraoperative opioid administration in patients receiving surgery under general anesthesia. ⋯ Analgesia nociception index-guided analgesia was unable to reduce intraoperative opioid administration compared to monitoring using conventional clinical parameters. Further studies are required to support our findings.

At this centenary of the British Journal of Anaesthesia (BJA) in 2023, six of its 12 editors/editors-in-chief detail developments over the decades that have led to the BJA becoming a high-impact international scientific journal. As a charity, the BJA supports academic research and training in anaesthesia, critical care, and pain medicine including funding of research grants and postgraduate education. Building on this foundation, the BJA continues to innovate as it aims to become fully electronic, expand into open access publishing, and increase the diversity of its editorial board.
