Isoflurane is associated with a similar incidence of emergence agitation/delirium as sevoflurane in young children ? a randomized controlled study
2006
Summary Background: Children may be agitated or even delirious especially when recovering from general anesthesia using volatile anesthetics. Many trials have focused on the newer agents sevoflurane and desflurane but for the widely used isoflurane little is known about its potential to generate agitation. We investigated the emergence characteristics of small children after sevoflurane or isoflurane with caudal anesthesia for postoperative pain control. Methods: After institutional approval and parental consent, anesthesia was randomly performed with sevoflurane (n = 30) or isoflurane (n = 29) in children at the age of 3.8 ± 1.8 years during surgical interventions on the lower part of th…
Economic Considerations of the Use of New Anesthetics
1998
UNLABELLED: Cost control in anesthesia is no longer an option; it is a necessity. New anesthetics have entered the market, but economic differences in comparison to standard anesthetic regimens are not exactly known. Eighty patients undergoing either subtotal thyroidectomy or laparoscopic cholecystectomy were randomly divided into four groups, with 20 patients in each group. Group 1 received propofol 1%/sufentanil, Group 2 received desflurane/sufentanil, Group 3 received sevoflurane/sufentanil, and Group 4 received isoflurane/sufentanil (standard anesthesia) for anesthesia. A fresh gas flow of 1.5-2 L/min and 60% N2O in oxygen was used for maintenance of anesthesia, and atracurium was given…
Новый ЛЕФ и киновещь
2019
Abstract In the 1920s, the LEF project moved the discussion about the role of “things in film” – as metonymic and metaphoric, photogenic and functional, and as tools that filled gaps in the narrative, stood in for actors, or operated as generic markers – in a distinctly materialist direction. Sergei Eisenstein and Dziga Vertov were sharply criticized for turning things into symbols in their films. To avoid this aesthetic dispute, Tret’iakov advocated production scripts based on the dominance of material things over plot. Eisenstein, in his unfinished text ‘Play of Objects' (‘Ob igre predmetov’), offers another understanding of things in film. A film-thing (kinoveshch’), in his reading, is f…
Aesthetics of Geometry and the Problem of Representation in Monument Sculpture
2017
Since the 1920s and 1930s, constructivist and concretist visual art movements have stressed geometric forms, proportions and orders as a base for artistic expressions and aesthetic experiences. After the World War II geometric form was adopted to the public sculpture. Abstract, geometrically constructed sculpture was also used in commemorative functions in modern monument art. The combination of the commemoration of a significant historical event or a national hero, and the aesthetic ideas based on constructivist or concretist art movements caused a lot of debates and confrontations in many Western countries. In particular, the interpretation of abstract monuments problematized: abstract mo…
Invisible Ends Justify Secret Means: Homeland, Machiavelli, and the Least of All Possible Evils
2021
In the rhetoric informing Niccolò Machiavelli’s thought and the contemporary War on Terror, the dialectic between ethics and necessity within the framework of the process of secularization represents a cohesive thread. This very dialectic constitutes also the narrative principle presiding Homeland, one of most insightful TV shows having developed a critical reflection about the present time so far. Dealing with terrorist practices and counterterrorism tactics, the series provides an accurate depiction of the fears featuring nowadays Western societies and the means through which American institutions attempt to answer them . This essay proposes a survey of the conceptual core belonging to th…
Stimulation of hippocampal acetylcholine release by hyperforin, a constituent of St. John’s Wort
2004
Abstract Extracts of the medicinal plant St. John’s Wort ( Hypericum perforatum ) are widely used in the therapy of affective disorders and have been reported to exert antidepressant, anxiolytic, and cognitive effects in experimental and clinical studies. We here report that hyperforin, the major active constituent of the extract, increases the release of acetylcholine from rat hippocampus in vivo as determined by microdialysis. Hippocampal acetylcholine levels were increased by 50–100% following the systemic administration of pure hyperforin at doses of 1 and 10 mg/kg. The effect was almost completely suppressed by local perfusion with calcium-free buffer or with tetrodotoxin (1 μM). We co…
The Blaumanis Moment: National Literature Enters the Stage of Art
2012
My aim in this article is to discuss the literary field in Latvia slightly before 1900. More specifically, I want to focus on the particular situation when literature written in the Latvian language ceases to be a product of didactic intention and moralizing value, and makes the crucial step in recognizing its rights to submerge into primarily aesthetic issues. It is also the moment when the personality of the author cuts through the still mostly realistic surface of literary works, making him (or her) be perceived as unmistakably present, even if this move often remains unnoticed by most contemporary and even later observers.1 The author who in my article represents this departure, which u…
Evaluation of the anaesthetic properties and tolerance of 1:100,000 articaine versus 1:100,000 lidocaine. : a comparative study in surgery of the low…
2011
Objectives: To evaluate the anaesthetic properties and tolerance of articaine versus lidocaine at equal vasoconstrictor concentration. Study Design: A total of 96 male and female patients who underwent surgical treatment of the lower third molar participated. Patients were randomly assigned to articaine hydrochloride with epinephrine 1:100,000 and lidocaine hydrochloride with epinephrine 1:100,000. The variables analysed were latency period, duration of anaesthetic effect, tolerance and adverse reactions. Results: Both the latency period and the duration of anaesthetic effect were greater for articaine, although the differences were not statistically significant. Latency: mean difference of…
Can buccal infiltration of articaine replace traditional inferior alveolar nerve block for the treatment of mandibular molars in pediatric patients?:…
2021
Background It is unclear if buccal articaine infiltration can be used as an alternative to standard inferior alveolar nerve block (IANB) for treating mandibular molars in pediatric patients. Therefore, this study aimed to pool evidence to compare the efficacy of buccal infiltration of articaine vs IANB with lignocaine for pediatric dental procedures. Material and Methods We searched the PubMed, Embase, ScienceDirect, CENTRAL, and Google Scholar databases for randomized controlled trials (RCTs) comparing the two techniques in pediatric patients and reporting the success of anesthesia and/or pain during treatment. PRISMA guidelines were followed. Results Seven RCTs were included. Pooled analy…
Glossary of Morphology
2020
This book is a significant novelty in the scientific and editorial landscape. Morphology is both an ancient and a new discipline that rests on Goethe's heritage and re-forms it in the present through the concepts of form and image. The latter are to be understood as structural elements of a new cultural grammar able to make the late modern world intelligible. In particular, compared to the original Goethean project, but also to C.P. Snow's idea of unifying the “two cultures”, the fields of morphological culture that are the object of this glossary have profoundly changed. The ever-increasing importance of the image as a polysemic form has made the two concepts absolutely transitive, so to s…
