    Defect clusters and thermoluminescence in LiF crystals (1999)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 86 (1999), S. 1410-1414

    Notizen: The thermoluminescence of pure and doped LiF crystals has been measured following irradiation at ambient temperature with gamma and x rays. Factors investigated include the effects of dopants (Mg, Mg/Ti, and Fe) and of dose. Results are compared with optical absorption and photoluminescence measurements made previously on the same crystals. The role of F, F3+, Z2, and colloids in the emission process is discussed. Some new effects are reported including step-like features in the glow curves at large doses. These are explained in terms of the clustering of interstitial defects formed during radiolysis. © 1999 American Institute of Physics.

    Formation producibility and fractional flow curves from radial resistivity variation caused by drilling fluid invasion (1997)
    [S.l.] : American Institute of Physics (AIP)

    Notizen: In order to characterize conductivity profiles due to drilling fluid invasion into a hydrocarbon formation, a model for radial fluid transport is presented. The model assumes a water-based mud and accounts for the convective movement of oil, water, and salt. A mathematical analysis of the model using the method of characteristics is given. An equivalent graphical construction is also provided. Computations of radial conductivity profiles for specified formation characteristics and total filtrate loss are given. For typical fractional flow curves, it is shown that three qualitatively different profiles may occur depending on the initial water saturation. These results are compared with numerical simulations that include capillary pressure and gravity segregation. Next, the important issue of the inverse problem is analyzed. It is shown that from a single snapshot of the conductivity profile, an exact calculation of filtrate loss and formation fractional flow curve is possible. The calculation is valid provided there is a resistivity contrast between the drilling fluid filtrate and the formation water. For practical application, we show the limits of applicability of this result with complete numerical calculations. Thus, if wireline logs of resistivity variation away from the wellbore are available, formation oil producibility and water cut at native conditions may be estimated. © 1997 American Institute of Physics.

    The occurrence of bacteraemia associated with the use of oral and nasopharyngeal airways (1992)
    Oxford, UK : Blackwell Publishing Ltd
    Anaesthesia 47 (1992), S. 0 
    Details

    Thema: Medizin
    Notizen: In order to determine whether placement of oral or nasopharyngeal airways during anaesthesia induces a significant bacteraemia, 36 ASA grade 1 or 2 patients undergoing body surface surgery, in whom it was anticipated that spontaneous respiration would be maintained, were randomly allocated to one of two groups. One group was given oral airways and the other, nasopharyngeal. A series of blood samples, which were taken before and after airway insertion, were cultured aerobically and anaerobically. Nasal and oral swabs were taken at the same time. Single isolates of Corynebacterium species and Acinetobacter species, together with two isolates of Staphylococcus epidermidis were grown from one culture bottle from 4 of the 36 patients studied. None of the oral or nasal swabs, or any of the subsequent or previous blood samples produced positive cultures for these organisms in these four patients. We believe that these results represent skin commensal contamination rather than bacteraemia in these four patients, and that bacteriological considerations should not influence decisions about the type of airway used during anaesthesia. However, prophylactic antibiotic therapy should still be provided for all high risk cases.

    Notizen: A new oesophageal intubation detector device, the Fenem CO2 detector, was used in 100 patients intubated during anaesthesia for elective surgery. This new device was 100% accurate in the differentiation between tracheal and oesophageal placement of a tube.

    Anaesthetic management in Moya-moya disease (1985)
    Oxford, UK : Blackwell Publishing Ltd
    Anaesthesia 40 (1985), S. 0

    ISSN: 1365-2044

    Thema: Medizin
    Notizen: A case of Moya-moya disease requiring anaesthesia for both investigation and attempted surgical correction is presented. The influence of the anaesthetic technique on the abnormal cerebral vasculature, with particular reference to induced hypocapnia, is discussed. Guidelines for a safe method of anaesthesia in this group of patients are suggested.

    Decontamination of laryngoscopes: a survey of national practice[A summary ] (1999)

    Notizen: We conducted a postal questionnaire to survey methods of laryngoscope cleaning in units throughout Great Britain. We found that there was great variation in practice. Most units autoclave laryngoscope blades at some time, but less than one-quarter do so between each case. A wide range of methods is used to clean the blade in units where autoclaving was not undertaken. Most units had no guidelines relating to laryngoscope treatment between uses.

    Dr F. P. de Caux—the first user of curare for anaesthesia in England (1991)
    Oxford, UK : Blackwell Publishing Ltd
    Anaesthesia 46 (1991), S. 0 
    Details
    ISSN: 1365-2044
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Medizin
    Notizen: Curare was used in the 19th century in England by a wide variety of scientists, physicians and veterinarians. Their experiments indicated many of the properties of the drug, but its clinical usage remained very limited and was reserved for cases of tetanus, hydrophobia and strychnine poisoning. Griffith and Johnson are usually credited with the introduction of curare into clinical anaesthesia in 1942, but a Dr F.P. de Caux working at the North Middlesex Hospital, London, in 1928 utilised curare in a series of seven patients. His work was not widely publicised and this contribution to anaesthetic history has been overlooked by subsequent authors.

    Ginger root—a new antiemetic The effect of ginger root on postoperative nausea and vomiting after major gynaecological surgery (1990)
    Oxford, UK : Blackwell Publishing Ltd

    Thema: Medizin
    Notizen: The effectiveness of ginger (Zingiber officinale) as an antiemetic agent was compared with placebo and metoclopramide in 60 women who had major gynaecological surgery in a double-blind, randomised study. There were statistically significantly fewer recorded incidences of nausea in the group that received ginger root compared with placebo (p 〈 0.05). The number of incidences of nausea in the groups that received either ginger root or metoclopramide were similar. The administration of antiemetic after operation was significantly greater in the placebo group compared to the other two groups (p 〈 0.05).
