Silencing SP1 Alleviated Sevoflurane-Induced POCD Development via Cholinergic Anti-inflammatory Pathway.
Abstract Postoperative cognitive dysfunction (POCD) is a common complication induced by anesthesia or surgery, which affects the concentration, cognition and memory of patients. Sevoflurane, a clinical anesthetic, could stimulate neuro-inflammation and lead to POCD. Recent studies found that specificity protein 1 (SP1) participates in the development of neurological diseases. Our study aims to elucidate the role of SP1 in sevoflurane-induced POCD pathogenesis. We anesthetized Sprague-Dawley rats and treated the primary hippocampal neurons with sevoflurane to construct the in vivo and in vitro POCD models. Besides,...

General Anesthesia Maintained with Sevoflurane versus Propofol in Pediatric Surgery Shorter Than 1 Hour: A Randomized Single-Blind Study.
Authors: Wu G, Xu X, Fu G, Zhang P Abstract BACKGROUND Sevoflurane was compared with propofol for general anesthesia maintenance in pediatric operations lasting less than 1 hour in terms of anesthetic effect and postoperative recovery. MATERIAL AND METHODS Children scheduled for inguinal hernia repair or hydrocele testis repair were randomly assigned to receive general anesthesia maintained with either sevoflurane (n=43) or propofol (n=43). The ilioinguinal nerve was blocked with 1% lidocaine (7 mg/kg) after intravenous administration of ketamine (2 mg/kg). At the end of the surgery in patients receiving sevofluran...

Inhaled Anesthetic Agents
General anesthesia refers to a drug-induced loss of consciousness during which patients are not arousable, even by painful stimuli and often have impaired ventilatory function.1 Inhaled anesthetic gases can be administered to impart general anesthesia and are often administered adjunctively with intravenous sedatives (eg, propofol, fentanyl, midazolam) to maintain appropriate depths of anesthesia throughout the surgical case.2 Inhaled anesthetic agents include isoflurane, sevoflurane, desflurane, and nitrous oxide (N2O).

New Method of Destroying Waste Anesthetic Gases Using Gas-Phase Photochemistry.
on MS Abstract BACKGROUND: The inhalation anesthetics are potent greenhouse gases. To reduce the global environmental impact of the health care sector, technologies are sought to limit the release of waste anesthetic gas into the atmosphere. METHODS: Using a photochemical exhaust gas destruction system, removal efficiencies for nitrous oxide, desflurane, and sevoflurane were measured at various inlet concentrations (25% and 50%; 1.5%, 3.0%, and 6.0%; and 0.5%, 1.0%, and 2.0%, respectively) with flow rates ranging from 0.25 to 2.0 L/min. To evaluate the economic competitiveness of the anesthetic waste gas dest...

Combination of intramuscular alfaxalone, butorphanol, and midazolam as a novel immobilization protocol in 3 ring-tailed lemurs ( Lemur catta )
ConclusionsThe combination of intramuscular alfaxalone, butorphanol and midazolam provided a clinically useful sedation/immobilization in ring-tailed lemurs with only minor complications such as mild hypothermia, hypotension, hypoventilation and bradycardia. This protocol could be considered in ring-tailed lemurs that need to be immobilized for minor procedures, or as a pre-anaesthetic premedication, especially if a full pre-anaesthetic clinical exam is not possible.

Hippocampus is more vulnerable to neural damages induced by repeated sevoflurane exposure in the second trimester than other brain areas.
Abstract During the rapidly developing and sensitive period of the central nervous system (CNS), a harmful stimulus may have serious consequences. The effect of anesthetic exposure on the development of the offspring's CNS during pregnancy is still unclear and has been widely concerned. In the present study, we compared the susceptibility of the hippocampus with those of other brain regions in offsprings when the mother mice were exposed to repeated sevoflurane. We found that other than affecting motor sensation, emotion, or social behavior of offspring mice, repeated sevoflurane exposure induced significant memor...

COVID-19 and heme oxygenase: novel insight into the disease and potential therapies.
Abstract The COVID-19 pandemic needs therapies that are presently available and safe. We propose that subjects with metabolic syndrome, old age, and male gender have the greatest morbidity and mortality and have low stress proteins, in particular, low intracellular heme oxygenase (HO-1), making them particularly vulnerable to the disease. Additionally, COVID-19's heme reduction may contribute to even lower HO-1. Low-grade inflammation associated with these risk factors contributes to triggering a cytokine storm that spreads to multi-organ failure and near death. The high mortality of those treated with ventilator ...

Optimization of Ultrasound Backscatter Spectroscopy to Assess Neurotoxic Effects of Anesthesia in the Newborn Non-human Primate Brain
Studies in animal models have revealed that long exposures to anesthetics can induce apoptosis in the newborn and young developing brain. These effects have not been confirmed in humans because of the lack of a non-invasive, practical in vivo imaging tool with the ability to detect these changes. Following the successful use of ultrasound backscatter spectroscopy (UBS) to monitor in vivo cell death in breast tumors, we aimed to use UBS to assess the neurotoxicity of the anesthetic sevoflurane (SEVO) in a non-human primate (NHP) model.

Neurotoxicity of sub-anesthetic doses of sevoflurane and dexmedetomidine co-administration in neonatal rats.
CONCLUSIONS: In the neonatal rat model, co-administration of a clinically relevant dose of DEX (1 µg/kg) with a sub-anesthetic dose of SEVO (1.1%) does not affect the neurotoxicity of the anesthetic while co-administration of higher doses of DEX with SEVO 1.1% potentiates it.
