In advanced cancer patients close to death, delirium, multifocal myoclonus, and restlessness may occur. Multi-organ failure and related metabolic changes are mostly responsible for these symptoms. A pharmacologic approach to manage the delirium is necessary in the majority of cases. Benzodiazepines, neuroleptics, and barbiturates are the most common drugs used. In the case reported, propofol administered at very low doses provided good control of neuropsychiatric symptoms. After a loading dose of 20 mg, an infusion of 50-70 mg per hr was started. The patient died peacefully after 8 hr of propofol infusion, without requiring opioids. Propofol seems to be a promising drug in treating the terminal agitated state that can be associated with the dying process.

Aim: The aim of this study was to compare the effects of dexmedetomidine, midazolam, propofol, and intralipid on lidocaine-induced cardiotoxicity and neurotoxicity.
Methods: Forty-eight male Sprague-Dawley rats were randomly divided into six groups (n = 8 per group): control (C), lidocaine (L), lidocaine + dexmedetomidine (LD), lidocaine + midazolam (LM), lidocaine + propofol (LP), and lidocaine + intralipid (LI). Dexmedetomidine (100 µg/kg), midazolam (4 mg/kg), propofol (40 mg/kg), and intralipid (10 mg/kg) were administered intraperitoneally as pretreatment.

Objective: We investigated the mechanism of Dexmedetomidine (Dex) in infant rats with brain injury.
Methods: The infant rats underwent brain injury modelling. The motor function, spatial learning and memory abilities in rats, and the hippocampal CA1 region Nissl body level and apoptosis were evaluated by behavioural tests and histological stainings.

Awake craniotomy (AC) facilitates real-time brain mapping, maximizing tumor resection while preserving critical neurological functions. This study systematically reviews the efficacy of several anesthetic protocols under Monitored Anesthesia Care (MAC) during AC, focusing on clinical outcomes. A systematic review and meta-analysis were conducted using data from observational studies and randomized trials involving AC under MAC.

Background: Emergence agitation (EA) occurs in preschool children after ophthalmic surgery as eye shields induce visual disturbance. We aimed to investigate the efficacy of light-transmitting eye shields as an alternative to traditional medical gauze eye shields for wound dressing in terms of EA incidence following strabismus surgery.
Methods: We randomly assigned 70 preschool children undergoing bilateral strabismus surgery to receive either light-transmitting (LT group, n = 35) or medical gauze (MG group, n = 35) eye shields upon the completion of surgery.
Objective: This study aimed to evaluate whether pretreatment with gabapentin or alprazolam in cats increases sedation, facilitates intravenous catheter placement (IVCP), or reduces propofol requirements for intubation compared to placebo.
Methods: All cats that participated in this prospective, randomized, blinded, controlled clinical trial were admitted for elective ovariohysterectomy at a veterinary teaching hospital from 2022 to 2023. The cats were healthy, were ≥ 6 months old, and weighed > 3 kg.
