ReviewA Scoping Review of the Mechanisms Underlying Developmental Anesthetic Neurotoxicity.
Although anesthesia makes painful or uncomfortable diagnostic and interventional health care procedures tolerable, it may also disrupt key cellular processes in neurons and glia, harm the developing brain, and thereby impair cognition and behavior in children. Many years of studies using in vitro, animal behavioral, retrospective database studies in humans, and several prospective clinical trials in humans have been invaluable in discerning the potential toxicity of anesthetics. The objective of this scoping review was to synthetize the evidence from preclinical studies for various mechanisms of toxicity across diverse experimental designs and relate their findings to those of recent clinical trials in real-world settings.

Randomized Controlled TrialThe effect of intravenous lidocaine infusion on subarachnoid anesthesia in patients undergoing total knee replacement: a randomised controlled trial.
Intravenous lidocaine is a non-opioid analgesic adjunct for perioperative pain relief. The aim of our study was to explore whether concurrent administration of intravenous lidocaine prolongs the duration of sensory block during total knee replacement (TKR) under spinal anaesthesia. ⋯ During unilateral TKR under spinal anaesthesia, concurrent use of intravenous lidocaine prolonged sensory block and reduced postoperative analgesic requirements.

Awake craniotomies with functional cortical mapping are performed to minimize post-operative deficits from the resection of lesions adjacent to eloquent cortex. The procedure is well-established in the adult patient population and is increasingly applied to well-selected pediatric patients. A review of recent literature demonstrated that the most commonly reported anesthetic techniques were "asleep-awake-asleep" protocols that relied on propofol, remifentanil, or fentanyl. ⋯ Awake craniotomies can safely be performed in the pediatric population with appropriate patient sel7ection, planning, and a multi-disciplinary approach.

Intravenous lidocaine is increasingly used as a nonopioid analgesic, but how it acts in the brain is incompletely understood. We conducted a functional MRI study of pain response, resting connectivity, and cognitive task performance in volunteers to elucidate the effects of lidocaine at the brain-systems level. ⋯ NCT05501600.

Life cycle assessment is increasingly used in the healthcare sector to facilitate more environmentally informed supply and medication use. A thorough life cycle assessment comparing the carbon impacts of 10 different single-use anaesthetic drug trays yielded surprising findings. Although life cycle assessment can guide decision-making, results must be interpreted clinically and in light of all available options, including eliminating unnecessary consumption altogether. Effective life cycle assessment in healthcare that is clinically applicable requires expertise from both environmental scientists and clinicians.
