ReviewKeeping patients in the dark: perioperative anesthetic considerations for patients receiving 5-aminolevulinic acid for glioma resection.
5-Aminolevulinic acid hydrochloride (5-ALA), available under the trade name Gleolan, is an orally administered fluorophore drug used to enhance visual differentiation of cancerous tissue from healthy tissue, primarily during surgical resection of high-grade gliomas. Although given preoperatively, 5-ALA has important implications for anesthetic care throughout the perioperative period. This article reviews pharmacology, safety concerns, and perioperative considerations for patients who receive oral 5-ALA. ⋯ Mitigating the possible side effects of 5-ALA requires an understanding of its basic mechanism as well as focused perioperative planning and communication. Administration of this medication may result in nausea, vomiting, photosensitivity, increase in serum concentration of liver enzymes, and hypotension. Patients who receive 5-ALA must be protected from prolonged light exposure during the first 48 h after consumption and administration of other photosensitizing agents should be avoided (Supplemental Video File/Video abstract).

Although effects of general anesthesia on neuronal activity in the human neonatal brain are incompletely understood, electroencephalography provides some insight and may identify age-dependent differences. ⋯ Although evidence gaps were identified, both increasing sevoflurane concentration and decreasing temperature are associated with increasing discontinuity.

ReviewOptimizing peripheral regional anaesthesia: strategies for single shot and continuous blocks.
Regional anaesthesia is increasingly prominent within anaesthesia, offering alternative analgesic options amidst concerns over opioid-based analgesia. Since Halsted's initial description, the field has burgeoned, with ultrasound visualization revolutionizing local anaesthetic spread assessment, leading to the development of numerous novel techniques. The benefits of regional anaesthesia have gained increasing evidence to support their application, leading to changes within training curricula. Consequently, regional anaesthesia is at a defining moment, embracing the development of core skills for the general anaesthesiologist, whilst also continuing the advancement of the specialty. ⋯ This review highlights recent scientific advances in optimizing both single-shot and continuous peripheral regional anaesthesia techniques. By synthesizing these developments, this review offers valuable insights into the evolving landscape of regional anaesthesia, aiming to improve clinical practice and patient care.

Review Comparative StudyTotal Intravenous Anesthesia Is Preferred Over Volatile Agents in Cardiac Surgery.
The choice of maintenance anesthetic during cardiopulmonary bypass has been a subject of ongoing debate. Systematic reviews on the topic have so far failed to demonstrate a difference between volatile agents and total intravenous anesthesia (TIVA) in terms of mortality, myocardial injury, and neurological outcomes. Studies using animal models and noncardiac surgical populations suggest numerous mechanisms whereby TIVA has been associated with more favorable outcomes. However, even if the different anesthetic methods are assumed to equivalent in terms of patient outcomes in the context of cardiac surgery, additional factors, namely variables of occupational exposure and environmental impact, strongly support the preferred use of TIVA.
