Shedding Light On General Anesthesia: Uncovering The Molecular Mechanisms For Propofol And Volatile Anesthetics
General anesthetics have played a pivotal role in the history of medicine. Despite accounts of their use within the earliest of human records, our understanding of anesthetic mechanisms remains unclear. Understanding these molecular mechanisms would be a significant advance toward enhanced drug …

Wirkung von milder Hypothermie auf den negativ inotropen Effekt von Halothan, Isofluran und Sevofluran auf ventrikuläres Kaninchen-Myokard
… changes the negative inotropic response of the volatile anesthetics halothane, isoflurane and sevoflurane on ventricular rabbit myocardium. Measured parameters were contractility, the timing of contractions, response to the raise of extracellular calcium concentrations and the first contraction …

Einfluss der Inhalationsanästhetika Sevofluran und Desfluran auf die Ausbildung von Adhäsionsmolekülen auf Granulozyten in vitro
Volatile anesthetics are reported to reduce ischemia-reperfusion injury. One suggested mechanism was the attenuated expression of CD11b on activated neutrophils after exposure to volatile anesthetics. However, neutrophil adhesion to vascular endothelium is a multistep process involving several …

Veränderung der Hämodynamik durch die Kombinationsnarkose aus Xenon und Isofluran im Vergleich zu der aus Xenon und Sevofluran an Schweinen
… were taken as baseline values. Therefore the volatile anesthetics were administered at 1.0, 1.3 and 1.6 MAC. After that measurements together with xenon and one of the volatiles were performed. Xenon was delivered at increasing levels (15%, 30%, 40%, 50% and 65%) and each xenon concentration …

Unsupervised tracking and automated analysis of multi-population neural activity under anesthesia
Volatile anesthetics play an essential role in the practice of modern medicine due to their widespread use in general anesthesia. Research on anesthetics has mainly involved studies of molecular effects on ion channels and receptors, or on alterations of gross neural activity across large brain …

Implementing a postoperative nausea and vomiting protocol for adult patients undergoing general anesthesia
… non-smokers, post-operative opioid use, use of volatile anesthetics and/or nitrous oxide, gynecological procedures, and laparoscopic procedures. Patients with 1-2 risk factors should receive 2 anti-emetics and those with >2 risk factors should receive 3-4 anti-emetics. A mid-Michigan teaching …

Reducing the global footprint in an anesthesia department : a quality improvement project
Volatile anesthetic agents are potent greenhouse gases with high global warming potential (GWP), long atmospheric lifespans, and significant contributions to perioperative emissions. Despite scavenging systems, a significant portion of these agents are released into the environment, with Desflurane …

The Role of Neuronal Leak Channels in Anesthesia
<p>Volatile anesthetics (VAs) cause profound effects, including reversible lossof consciousness and immobility. The mechanism of action of VAs remains oneof the great, unsolved puzzles of neuroscience and medicine. Recent geneticstudies revealed that mutations that change anesthetic sensitivity in …
