The impact of cricoid pressure on oesophagus position and compressibility in Malaysian patients: A prevalence study / Aaron Wilson
Get PDFBackground
Cricoid pressure (CP) is an airway manoeuvre used during rapid sequence induction to
reduce the risk of pulmonary aspiration. Classically it was thought that CP was effective
for this as it compressed onto the oesophagus located centrally. However, anatomical
studies involving CP showed various relative oesophagus positions with variable
degrees of compressibility, and ultrasound is a non-invasive tool that could be used to
assess these parameters.
Purpose:
To determine the sonographic prevalence of relative position of oesophagus to cricoid
cartilage in patients undergoing general anaesthesia; and to assess the qualitative impact
of CP on change of oesophagus position and its compressibility.
Methods
A prospective, cross-sectional study was performed on patients would undergo general
anaesthesia for elective surgery in single tertiary centre in Malaysia. Written consent
obtained from all eligible patients. Prior to induction of general anaesthesia, baseline
ultrasound scan of the neck to assess the position of oesophagus relative to cricoid
cartilage was done and designated as either: central, partially lateral, or completely
lateral. Scan was repeated post general anaesthesia and pre CP. Then CP force of 30N
was applied on cricoid cartilage. Patient’s sonogram was assigned to one of three
groups: directly behind the trachea (“central”), partially behind trachea (“partial”), or
completely lateral to the trachea (“lateral”). Oesophagus was assumed “central” (and
iii
compressible) if scan did not detect oesophagus; “partial”, if the entire tubular structure
of the oesophagus located behind cricoid cartilage was not visualised (lateral borders of
cricoid cartilage and the oesophagus overlapped); and “central”, if there lateral border
of the two structures overlapped. The position and compressibility of oesophagus were
recorded. Two investigators with fixed roles were involved in obtaining the data,
whereby one applied CP and the other performed the ultrasound scan of the neck. Chi
square test, McNemar or Fisher exact was performed for statistical analysis (α = 0.05).
Results
There were 50 patients recruited. Results pre vs post general anaesthesia were as follow:
44% (vs 34%) patients with central oesophagus, 42% (vs 44%) were partial and 14%
(vs 22%) lateral. The effect of general anaesthesia on oesophagus placement was
significant (p = 0.046). There is no change in oesophagus position pre and post CP.
There was higher prevalence (54%) of oesophagus occlusion with CP in the central and
partial groups (p <0.001). No oesophagus occlusion seen in lateral group.
Conclusions
There was more non-centrally located oesophagus compared to central oesophagus.
Anaesthesia effect has an association with further displacing the oesophagus.
Oesophagus occlusion was less likely if it is deviated from cricoid cartilage
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
