    Transient signals from a buried horizontal magnetic dipole (1973)

    Notes: Summary The impulse response for a horizontal magnetic dipole buried in a conducting half-space is obtained in closed form by an inverse Fourier transform of the known time harmonic solution. Since displacement currents are neglected, the response is not valid for very short times. The waveforms of the magnetic field components at the surface have geometrical dependences which may have application to source location.

    Notes: Abstract The electromagnetic fields of an electric dipole located inside a cylindrical cavity or empty tunnel are formulated. The results are used to deduce an expression for the change of self-impedance due to the presence of the cavity or tunnel walls. A numerical evaluation of the resultant convergent integral and a summation of the angular harmonic series were performed. An important finding is that the input resistance of the dipole is approximately a constant for frequencies less than about 25 MHz for a typical tunnel radius of 2 m. Such results are shown to be in qualitative agreement with an earlier analysis of an electric dipole over a dissipative half-space.

    Epidural infusion of alfentanil or diamorphine with bupivacaine in labour—a dose finding study (1995)
    Oxford, UK : Blackwell Publishing Ltd

    Details

    Topics: Medicine
    Notes: Following induction of epidural analgesia with 0.375% bupivacaine, 120 healthy parturients were randomly assigned in a double blind fashion to one of eight infusion groups. All received 8ml.h-1 of0.125% bupivacaine either alone (control group), or with alfentanil at 133, 266 or 400μg.h-1 (groups A1-A3) or with diamorphine at 133, 266, 400 or 533μg.h1 (groups D1-D4). Significantly longer top-up intervals were achieved with the two highest doses of both alfentanil and diamorphine when compared with bupivacaine alone (p〈0.01), making the minimum effective doses 266 μg.h-1 of alfentanil and 400 ng.h-1 of diamorphine. Perineal analgesia was better in all the opioid groups compared with the control group (p 〈 0.05). The intensity of motor block was greater in the control group (p 〈 0.05). The incidence of pruritus did not differ between groups. The highest dose of diamorphine caused significantly more nausea. No significant neonatal side-effects were demonstrated.

    Two approaches to the axillary brachial plexus (1992)

    Notes: A new technique of cannulation of the axillary neurovascular sheath, using loss of resistance to saline, was evaluated and compared to the established technique of eliciting paraesthesiae with a short-bevelled needle. The cannulation technique produced a more reliable block of axillary, musculocutaneous and radial nerves, significantly fewer incomplete blocks and a lower incidence of accidental vessel puncture.

    The effect of alkalinisation of lignocaine on axillary brachial plexus anaesthesia (1996)
    Oxford, UK : Blackwell Publishing Ltd

    Topics: Medicine
    Notes: Alkalinisation of local anaesthetic drugs is a controversial technique for improving regional blockade. Forty-two patients scheduled for upper limb surgery received axillary brachial plexus anaesthesia using a cannula technique. Patients were randomly allocated to receive either lignocaine 1.5% with 1 in 200 000 adrenaline (pH = 4.2) or lignocaine 1.5% with I in 200000 adrenaline (pH = 7.2). There was no significant difference in the incidence of satisfactory blockade or distribution of anaesthesia between the two groups. The percentage of patients with complete anaesthesia at 10, 20 and 30 min following injection was significantly increased in the alkalinised group with regard to the ulnar and median nerves, and the median cutaneous nerve of the arm (p 〈 0.05). In the alkalinised group, there was a significant reduction in the time to useful anaesthesia and a reduced requirement for adjuvants (p 〈 0.05). There was no effect on the duration of anaesthesia.

    Respiratory effects of spinal anaesthesia for Caesarean section (1996)

    Details
    ISSN: 1365-2044

    Topics: Medicine
    Notes: We report the changes observed in a number of pulmonary function tests performed on 36 patients undergoing Caesarean section under spinal anaesthesia. The tests comprised peak expiratory flow, forced expiratory volume in one second, forced vital capacity, forced expiratory volume in one second to forced vital capacity ratio and the maximal mid-expiratory flow. Significant changes occurred that are consistent with a restrictive ventilatory defect. These changes persisted for four hours after the induction of spinal anaesthesia. Administration of 35% oxygen by facemask failed to change significantly fetal umbilical vein pH or partial pressure of oxygen.

    Diagnostic gold standard for soft tissue tumours: morphology or molecular genetics? (2000)
    Oxford, UK : Blackwell Science Ltd
    Histopathology 37 (2000), S. 0 
    Details
    ISSN: 1365-2559
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: The recognition of recurrent genetic alterations in specific tumour types has provided the basis for the reclassification of certain soft tissue neoplasms, and molecular analysis of patient material has the potential to provide both diagnostic and prognostic information. In this review, we evaluate the role of molecular genetic testing as the prospective ‘gold standard’ for sarcoma diagnosis. Molecular genetic testing, as with every new method, promises to improve accuracy and to be more sensitive and less subjective, claims that have been made previously by histochemistry, electron microscopy and immunohistochemistry. Technical limitations in molecular assays, as well as more general specificity issues, decrease the clinical usefulness of molecular pathological testing significantly and suggest that, at present, molecular evaluation is best considered an ancillary technique that neither supersedes other ancillary techniques nor eclipses traditional pathological examination.

    Intrathecal alfentanil with and without bupivacaine for analgesia in labour (2000)

    Notes: Combined spinal–epidural (CSE) for analgesia in labour is widely used as a method of providing pain relief while minimising motor blockade. Aiming to further reduce the associated motor weakness, we investigated the use of alfentanil alone as the initial intrathecal injection in a double-blind study. Thirty women were randomly allocated to receive either alfentanil 0.25 mg with bupivacaine 2.5 mg intrathecally, or alfentanil 0.25 mg in the same volume. Onset of analgesia did not differ significantly between groups but duration was significantly longer in those receiving alfentanil–bupivacaine (mean 55 min vs. 40 min; p 〈 0.05). Quality of analgesia was satisfactory for all women, although the cumulative analgesia scores were significantly lower in the women receiving the alfentanil–bupivacaine mixture (p = 0.003). More women in the alfentanil–bupivacaine group developed both a sensory level (15/15 vs. 6/15; p 〈 0.01) and sympathetic block (12/15 vs. 4/15; p 〈 0.01). Sixty per cent of women receiving the alfentanil–bupivacaine mixture demonstrated an impaired ability to straight leg raise compared with none of the women in the alfentanil–saline group (p 〈 0.01). The incidence of adverse effects in mother and fetus was similar in both groups. We conclude that intrathecal alfentanil 0.25 mg alone as part of a CSE technique provides rapid analgesia of satisfactory quality without detectable motor blockade.
