Special Devices for Regional Anaesthesia

The rapid growth of regional anaesthesia in the last 20 years has resulted in an increasing number of technical devices. Technical resources play a very considerable role in modern regional anaesthesia and they are being introduced to facilitate the quality performance of this type of anaesthesia. The task of this survey is to summarise the most important technical devices currently utilised for regional anaesthesia and to provide a review of the history of their introduction. Technical devices for performing regional anaesthesia could be divided in seven groups: 1) neurostimulation and simple needles and catheters; 2) neurostimulator with transcutaneous nerve stimulation (TENS); 3) ultrasonograph with a device to fix the probe; 4) devices for injection of local anaesthetics, such as perfusors, patient controlled analgesia systems and elastomeric infusion systems; 5) arm, leg and instruments supports; 6) regional anaesthesia injection monitor and data register devices, and 7) catheter fastenings and auxiliary materials. It is recommended that all of the apparatus applied should be classified to make it easier to acquire more immediate and understanding, and be easy to add this knowledge to the overall checklist before starting anaesthesia. The history of the introduction of technical equipment shows how much time was necessary for the development of modern regional anaesthesia methods.publishersversionPeer reviewe

Descartes'o žmogaus samprata

This article is an analysis of Rene Descartes’ considerations about the human being. Those considerations take us into the realm of philosophical anthropology. Referring to its base, Descartes analysed ontological and ethical problems. Contents of the Human mind and consciousness attracted the great scientist's attention. His conclusion, “Cogito ergo sum” - I think, therefore I exist – was dualistic and one-sided. Rational understanding of the human being brought the classics into the wrong propositions of the subject question.Straipsnyje nagrinėjama R. Descartes‘o žmogaus, kaip kūniškos ir mąstančios būtybės, samprata. Teigiama, kad R. Descartes praplėtė kūno sąvokos apimtį ir susiaurino sielos funkcijas, susiejo jas su mąstymo aktais. Kūniškas žmogaus buvimas intensyviai veikia sielos išgyvenimus. Mąstymas yra neabejotinai egzistuojantis, substanciškas ir žmogiškas fenomenas. R. Descartes, sekdamas šv. Augustinu, laikėsi radikalaus dualizmo: sielą ir kūną traktavo kaip lygiavertes, savarankiškas, substanciškas būtis, nereikalaujančias savo egzistavimo pagrindo. R. Descartes, griežtai atskyręs sielos ir materijos pasaulius, pakreipė gamtos, socialinių ir humanitarinių mokslų tyrimus į materiją, kurios matavimas ir pseudomatavimas tapo mokslo raidos pagrindu. Autorius teigia, kad vertingiausia R. Descartes‘o pažiūrose (nors ir nerealizuota) yra mąstančios esmės ir kūniškos substancijos vieningumo programa

A method of open cluster membership determination

A new method for the determination of open cluster membership based on a cumulative effect is proposed. In the field of a plate the relative x and y coordinate positions of each star with respect to all the other stars are added. The procedure is carried out for two epochs t_1 and t_2 separately, then one sum is subtracted from another. For a field star the differences in its relative coordinate positions of two epochs will be accumulated. For a cluster star, on the contrary, the changes in relative positions of cluster members at t_1 and t_2 will be very small. On the histogram of sums the cluster stars will gather to the left of the diagram, while the field stars will form a tail to the right. The procedure allows us to efficiently discriminate one group from another. The greater the distance between t_1 and t_2 and the more cluster stars present, the greater is the effect. The accumulation method does not require reference stars, determination of centroids and modelling the distribution of field stars, necessary in traditional methods. By the proposed method 240 open clusters have been processed, including stars up to m<13. The membership probabilities have been calculated and compared to those obtained by the most commonly used Vasilevskis-Sanders method. The similarity of the results acquired the two different approaches is satisfactory for the majority of clusters.Comment: 10 pages, 5 figure

Proper motions and membership probabilities of stars in the region of globular cluster NGC 6809

NGC 6809 is a luminous metal-poor halo globular cluster that is relatively easy to study due to its proximity and low concentration. Because of its high Galactic latitude (b = -23deg), interstellar reddening and contamination is not very high. We aim to determine the relative proper motion and membership probability of the stars in the wide area of globular cluster NGC 6809. To target cluster members reliably during spectroscopic surveys and both spatial and radial distributions in the cluster outskirts without including field stars, a good proper motion and membership probability catalogue of NGC 6809 is required.The archival data of two epochs with a time-base line of 7.1 years have been collected with Wide Field Imager (WFI) mounted on the 2.2m MPG/ESO telescope. The CCD images of both epochs have been reduced using the astrometric techniques as described in Anderson et al. (2006). The calibrated UBVI magnitudes have been derived using Stetson's secondary standard stars. We derived the relative proper motion and membership probabilities for \sim 12600 stars in the field of globular cluster NGC 6809. The measurement error in proper motions for the stars of V \sim 17 mag is 2.0 mas/yr, gradually increasing up to \sim 3 mas/yr at V = 20 mag. We also provide the membership probability for the published different types of sources in NGC 6809. An electronic catalogue with proper motion and membership probability for the stars will be available to the astronomical community.Comment: Accepted for publication in The A&A. 11 pages. 11 figures,5 Table

New membership determination and proper motions of NGC 1817. Parametric and non-parametric approach

We have calculated proper motions and re-evaluated the membership probabilities of 810 stars in the area of two NGC objects, NGC 1817 and NGC 1807. We have obtained absolute proper motions from 25 plates in the reference system of the Tycho-2 Catalogue. The plates have a maximum epoch difference of 81 years; and they were taken with the double astrograph at Zo-Se station of Shanghai Observatory, which has an aperture of 40 cm and a plate scale of 30 arcsec/mm. The average proper motion precision is 1.55 mas/yr. These proper motions are used to determine the membership probabilities of stars in the region, based on there being only one very extended physical cluster: NGC 1817. With that aim, we have applied and compared parametric and non-parametric approaches to cluster/field segregation. We have obtained a list of 169 probable member stars.Comment: 11 pages, 8 figures, A&A in pres
