    Postanaesthetic shivering in children (1996)

    Notizen: This study was designed to assess the incidence, severity and possible aetiological factors ofpostanaesthetic shivering in children. Three hundred and seventy-six children undergoing general anaesthesia were enrolled in the study. Tympanic membrane temperatures were recorded pre-operatively and every 15 min postoperatively in the recovery room until discharge to the ward. Also recorded were all anaesthetic data including fluid administration, methods of temperature preservation used, sedation scores and shivering (using a four-point scale). The overall incidence of shivering was 14.4%. Multiple regression analysis identified three factors that were significantly related to shivering: age, the administration of atropine and peri-operative temperature changes. Children who shivered rewarmed faster in the recovery room.

    The effect of passive smoking on the incidence of airway complications in children undergoing general anaesthesia (1996)
    Oxford, UK : Blackwell Publishing Ltd
    Anaesthesia 51 (1996), S. 0 
    Details

    Thema: Medizin
    Notizen: The aim of this study was to assess whether passive smoking affected the frequency of airway complications in children undergoing general anaesthesia. One hundred and twenty-five children undergoing general anaesthesia for elective daycase surgery were monitored for adverse respiratory events and desaturation during induction, intra-operatively and in the recovery room. Oxygen saturation was monitored throughout and a venous sample was taken for estimation of carboxyhaemoglobin levels. Parents were asked to fill in a questionnaire detailing their smoking habits. Sixty-three of the children were passive smokers with a potential daily exposure varying from 5–130 cigarettes. There was no difference in the frequency of respiratory events between passive smokers and those not exposed to cigarette smoke at induction or intra-operatively. However, in the recovery room, desaturation was significantly more common in passive smokers (p〈0.02). This was related to the cumulative number of cigarettes smoked by individuals to whom the child was exposed (p〈0.05). Neither carboxyhaemoglobin levels nor domiciliary address were predictive of desaturation. This study suggests that passive smoking contributes to postoperative arterial oxygen desaturation following general anaesthesia in children.

    Thema: Medizin
    Notizen: One hundred and fifty ASA 1 and 2 patients were randomly allocated to receive pethidine 25 mg (1 ml), lignocaine Wing (1 ml) or 0.9% saline (1 ml) on a double-blind basis, as pretreatment to reduce pain on injection of propofol. Both active treatments were significantly better than placebo at preventing pain (p〈0.01). Lignocaine was most effective in preventing pain in men (p〈0.05) whilst pethidine was more effective in women (p〈0.05).

    Pain relief with low-dose intravenous clonidine in a child with severe burns (1996)

    Notizen: Abstract  The case of an 11-year-old boy who suffered second and third degree burns to 78% of his body is reported. The large doses of morphine used as analgesia resulted in severe side effects: ventilatory dependence, impairment of gastrointestinal function and psychological disturbance. Intravenous lignocaine was added without benefit. The addition of low-dose intravenous clonidine, however, precipitated a dramatic reduction in morphine consumption with an attendant improvement in ventilatory, gastrointestinal and psychological functions.

    The design and development of a 140GHz beam-lead diode subharmonically pumped mixer (1992)
    Springer
    International journal of infrared and millimeter waves 13 (1992), S. 267-274

    Thema: Physik
    Notizen: Abstract The possibility of using beam-lead diodes in the design of a 140GHz subharmonically pumped mixer was investigated. An easily assembled, rugged mixer structure was developed which avoids the problems associated with present production techniques and reduces costs. The construction of the circuit developed makes it ideally suited to space and other environmentally demanding application. Computer analysis techniques were used to predict millimetre-wave performance and a large-scale low-frequency model was used to optimize the circuit. The millimetre-wave mixer was constructed using a circuit implemented on suspended substrate stripline. Results of millimetre-wave performance are presented.

    The charactization of high-speed swept reflectometer for plasma diagnostics on the RFX reversed-field pinch (1992)
    Springer
    International journal of infrared and millimeter waves 13 (1992), S. 309-318 
    Details
    ISSN: 1572-9559
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Physik
    Notizen: Abstract An ordinary mode IMPATT-based reflectometer operating over 26.5–110GHz has been developed for density diagnostic application on the RFX reversedfield pinch experimental fusion machine. The reflectometer uses polarization rotators located at the antennas for optimizing the polarization of the emitted E-field A sweep speed of 1.25ms for the full band is possible. Single subbands may be swept at a rate of 200us. The provision of polarization rotators and high-speed solid-state oscillators maximises the immunity of the system to the effects of high fluctuation frequencies and mode mixing due to high magnetic shear. The reflectometer uses an IMPATT oscillator system for the source which has not been used in previous reflectometer circuits. A previously unachievable temporal resulution is therefore available with this system. The reflectometer is the first to be developed for use on a reversed-field pinch (RFP) machine. Verification of reflectometer operation was achieved using plane metal targets to simulate the reflecting plasma cut-off layer. Targets were located at various distances from the antennas to cover the expected spatial reflection range. The theoretical and experimental characteristics were obtained by processing the intermediate frequency output of the detectors. Spurious signals are removed by calibrating the target data using residual fringe data. A zero-crossing detection algorithm was developed to accurately identify the beat fringes and to deduce the phase/frequency characteristic. Single subband and full sweep results are presented.

    Experimental and theoretical analysis of a waveguide based quasi-optical multiplier (1992)
    Springer
    International journal of infrared and millimeter waves 13 (1992), S. 679-704 
    Details

    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Physik
    Notizen: Abstract A design for a submillimeter quasi-optical multiplier is evaluated both experimentally and theoretically. It is concluded that multipliers should use separate pump and harmonic waveguides to facilitate independent optimisation of the fundamental and harmonics. In addition, the harmonic waveguide should be single moded at the output at least, to prevent power loss to higher order modes.
