Neocaridina davidi, a small freshwater shrimp native to Asia, specifically China, Japan, Korea, and Vietnam, possesses remarkable resistance to poor water quality and offers various advantages over other invertebrate species to examine crucial issues in neuroscience and other related areas. These advantages include robustness, ease of maintenance, and transparency, making them useful for in vivo studies with optical imaging techniques. Despite its suitability for research purposes, particularly in the fields of imaging and fluorescent techniques, the lack of attention given to this species has resulted in the absence of a robust and replicable sedation protocol for immobilization and safe manipulation. Consequently, researchers face challenges in performing experimental procedures while minimizing harm to this specimen. In this study, we have developed and evaluated a simple sedation protocol specifically designed for Neocaridina davidi, assessing its effectiveness using light microscopy and image processing.

Malignant hyperthermia is a rare, life-threatening hypermetabolic reaction that can strike unexpectedly in the emergency department, demanding swift recognition and intervention to save lives. This syndrome can be fatal if not treated and occurrs in 1 in 100,000 adults and 1 in 30,000 children, with a 3% to 5% mortality rate. Although often associated with perioperative environments, malignant hyperthermia should remain on the radar for emergency nurses, especially when patients exhibit sudden hyperthermia, muscle rigidity, and tachycardia after intubation or procedural sedation.

Background And Aim: Echocardiographic assessment in equines is typically performed on standing animals; however, no studies have evaluated left ventricular function in anesthetized mules using high-dose xylazine. Given the unique pharmacokinetics in mules and their higher anesthetic requirements, this study aimed to assess the effects of acepromazine-xylazine-diazepam-ketamine anesthesia, using the upper limit xylazine dose (1.6 mg/kg), on the left ventricular size and function in mules.

Introduction: Delirium, a common acute brain dysfunction in older adults, features rapid changes in attention, awareness, and thinking that fluctuate. It presents diversely with altered activity levels and sleep. Postoperative delirium (POD), often seen in the postanesthesia care unit, is a temporary mental status change, with hypoactivity being common.

Background: In pediatric intensive care units, pain, sedation, delirium, and iatrogenic withdrawal syndrome (IWS) must be managed as interrelated conditions. Although clinical practice guidelines (CPGs) exist, new evidence needs to be incorporated, gaps in recommendations addressed, and recommendations adapted to the European context.
Objective: This protocol describes the development of the first patient- and family-informed European guideline for managing pain, sedation, delirium, and IWS by the European Society of Paediatric and Neonatal Intensive Care.

ObjectiveThe sedation protocol for flexible fiberoptic bronchoscopy has long been a matter of inconclusiveness. The aim of this study was to evaluate the safety and efficacy of remimazolam combined with alfentanil in flexible fiberoptic bronchoscopy and provide insights for optimizing clinical anesthesia strategies.MethodsThis study was a randomized, single-blind controlled trial.
