Anaesthesia is a fundamental aspect of modern medical practice, enabling surgical and diagnostic procedures to be performed without pain or distress by inducing a reversible loss of sensation or consciousness. Anaesthetic drugs exert their effect by interrupting neural signal transmission, thereby ensuring patient comfort and procedural safety. This study investigates the structural properties of selected anaesthetic agents through the application of topological indices derived from molecular graph theory. Both degree-based and neighborhood degree-based indices are computed to characterize the physical and chemical behavior of the drugs. Furthermore, a Quantitative Structure-Property Relationship (QSPR) analysis, utilizing quadratic regression models, demonstrates strong correlations between these topological descriptors and various physicochemical parameters. The results provide valuable theoretical insights into structure-property relationships, contributing to the advancement of drug discovery and molecular design in pharmaceutical research.

Background: Volatile anesthetics are gaining recognition for their benefits in long-term sedation of mechanically ventilated patients with bacterial pneumonia and acute respiratory distress syndrome. In addition to their sedative role, they also exhibit anti-bacterial and anti-inflammatory properties, though the mechanisms behind these effects remain only partially understood. In vitro studies examining the prolonged impact of volatile anesthetics on bacterial growth, inflammatory cytokine response, and surfactant proteins - key to maintaining lung homeostasis - are still lacking.

Background: Medical societies around the world are exploring strategies to reduce their carbon footprint. In this context, organizational readiness can serve as an important facilitator for the success of change. In this study we assessed whether a series of educational interventions improved anesthesia departments' organizational readiness for climate change mitigation.

Autism is a neurodevelopmental condition associated with altered resting-state brain function. An increased excitation-inhibition ratio is discussed as a pathomechanism but in-vivo evidence of disturbed neurotransmission underlying functional alterations remains scarce. We compare local resting-state brain activity and neurotransmitter co-localizations between autism (N = 405, N = 395) and neurotypical controls (N = 473, N = 474) in two independent cohorts and correlate them with excitation-inhibition changes induced by glutamatergic (ketamine) and GABAergic (midazolam) medication.

No existing literature details infusion rates of remimazolam delivered by manually adjusted infusion pumps. This case report describes the administration of manually infused remimazolam to an 86-year-old man for the surgical extraction of third molars under procedural sedation.

Objective: The purpose of this study was to compare nitrous oxide (N2O) vs virtual reality (VR) as methods for reducing pain and anxiety during a dental injection. The primary objectives were to assess acute changes in stress responses by comparing salivary cortisol levels between the 2 groups and differences in injection pain scores.
Methods: A total of 132 female subjects serving as their own control received maxillary lateral incisor infiltration injections with the use of either N2O or a VR headset during separate appointments spaced at least 2 weeks apart.
