    Clinical evaluation of the ‘T-Dagger™’: a new bedside percutaneous dilational tracheostomy device (2005)

    Notes: A number of percutaneous dilational tracheostomy devices are now available for clinical use. Recently, a new percutaneous dilational tracheostomy device, the ‘T-Dagger™’ (Criticure Invasives, India), has been introduced for rapid bedside percutaneous tracheostomy. In a prospective preliminary study, we have performed percutaneous dilational tracheostomy (PDT) using the T-Dagger™ in 20 adult ventilated patients in order to evaluate the safety and efficacy of the new device. The T-Dagger™ facilitated bedside PDT in about 3 min with no untoward incidents. There was no significant bleeding, pneumothorax, pneumomediastinum, tracheal wall injuries or difficulty in ventilation in any of the patients. We conclude that the T-Dagger™ shows early promise in bedside percutaneous dilational tracheostomy. However, controlled studies are required in a larger patient population before it can be recommended for routine use.

    Evaluation of capsaicin ointment at the Korean hand acupressure point K-D2 for prevention of postoperative nausea and vomiting (2005)

    Notes: The K-D2 point is the Korean hand acupressure point in Koryo Hand Therapy for prevention of postoperative nausea and vomiting. We evaluated the efficacy of capsaicin ointment at the K-D2 point in 186 patients undergoing laparoscopic cholecystectomy in a randomised, prospective, double-blind and placebo-controlled study. Patients were randomised to have either placebo ointment or capsaicin ointment applied to the K-D2 point of both hands 1 h before surgery under standardised anaesthesia. The ointment was removed 8 h later. Postoperative nausea and vomiting was evaluated 6 and 24 h following surgery. The incidence of postoperative nausea and vomiting was lower in the capsaicin group, with an absolute risk reduction (ARR) of 21%, a relative risk reduction (RRR) of 50% and a number-needed-to-treat (NNT) of 5 at 0–6 h (p = 0.001), and an ARR of 11%, a RRR of 85% and a NNT of 9 at 6–24 h (p = 0.003). The need for rescue anti-emetic treatment was also lower at 0–6 h (3 (3%) vs 11 (12%); p = 0.04) and at 6–24 h (5 (5%) vs 0; p = 0.02).

    Electrochemistry of copper in aqueous acetonitrile (1981)
    Springer
    Journal of solution chemistry 10 (1981), S. 757-774 
    Details
    ISSN: 1572-8927
    Keywords: Cu(II)/Cu(I) couple ; Cu(I)/Cu(0) couple ; acetonitrile-water mixtures ; Fe(III) ; 2-hydroxycyanoethane ; electrochemistry ; voltammetry

    Notes: Abstract The electrochemical characteristics of the Cu (II)/Cu (I) and the Cu (I)/Cu (0) couples at platinum, carbon, mercury and copper have been studied in acetonitrile-water (AN-H2O) mixtures. All the electrode processes are moderately fast with mercury the fastest but slower on platinum and carbon paste in that order. A slow chemical step precedes oxidation of Cu (I) to Cu (II) on allectrodes in solutions of high AN content. The slow step may be partial removal of AN from the solvated Cu (I) ion prior to electron transfer. Electrode processes are faster in chloride ions than in sulfate ion solutions. Reduction of Cu (I) in AN−H2O is quite slow on glassy carbon. Adsorption of AN on platinum and carbon influences the processes. Diffusion coefficients in sulfate solutions are in the order, Cu (I) (AN−H2O)〉Cu (II)(AN−H2O)〉Fe (III)(H2O) and 2-hydroxy-cyanoethane (2-HCE) strongly decreases the mobility of Cu (I) when added to H2O. The relevance of the measurements to hydrometallurgical processes is considered. CuSO4 in 30% v/v AN−H2O is a ‘faster’ oxidant than the common oxidant Fe2(SO4)3 in H2O because of the greater mobility and faster electron acceptance from a corroding surface of Cu (II). Only in solutions of very high nitrile content is the reduction potential of CuSO4 as high as that of Fe2(SO4)3 in H2O.

    Notes: Abstract The limiting conductance of various salts of Na+, Ag+, Cu+, Cu2+ and Ph4As+ in acetonitrile-water (AN-H2O) and pyridine-water (Py−H2O) mixtures are reported. Single ion values are calculated for AN-H2O mixtures using the TATB assumption [λo(Ph 4 As +) = λo(Ph 4 B −)]. The trends observed for the limiting Walden products (λoη) of the electrolytes and individual ions are discussed in terms of specific ion-solvent interactions and the structural effects of the solvent mixtures.

    Solvation of ions, part XXX. Thermodynamics of transfer of copper ions from water to solvent mixtures (1982)
    Springer
    Journal of solution chemistry 11 (1982), S. 495-508 
    Details
    ISSN: 1572-8927
    Keywords: Thermodynamic transfer quantities ; acetonitrile ; pyridine ; 2-hydroxycyanoethane ; aqueous organic solvent mixtures ; Cu2+, Cu+, and Ag+ ions ; hydrometallurgy
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Free energies and Walden products show that the Cu+ and Ag+ ions are specifically solvated by acetonitrile (AN), 2-hydroxycyanoethane (HAN), and by pyridine (Py) whereas Na+ is specifically solvated by water, in mixtures of these organics with water. The Cu2+ ion is specifically solvated by pyridine in pyridine-water mixtures, but by water in acetonitrile-water mixtures. Ion-solvent, coordinated solvent-bulk solvent, and solvent-solvent interactions produce large entropy losses in the order Cu+≫Ag+〉Na+ for transfer of these ions from water to dilute acetonitrile-water. The metallurgically important oxidations of copper, silver, CuS and Cu2 with CuSO4 in water are strongly favored in an enthalpic and free energy sense by the addition of acetonitrile, but addition of acetonitrile also produces a large loss of entropy for the reactions.

    On the possibility of the existence of NO+ in interstellar space (1980)
    Springer

    ISSN: 1572-946X

    Topics: Physics
    Notes: Abstract Frequencies are computed for transitions in the NO+ ion which are expected to occur in the millimeter and infrared regions usually covered by millimeter-wave and infrared astronomy. The emission cross-sections and spontaneous emission rates of the microwave transitions of NO+ ion are presented. The NO+ molecule is likely to be detectable in low-temperature sources whose state temperatures are not greater than 15 K. Transition probabilities and oscillator strengths for the Δv=1, 2, 3 and 4 vibration-rotation bands are derived from published theoretical dipole moment functions, obtained by an accurate multi-configuration self-consistent field procedure, in the1∑ ground state of NO+ ion. On the basis of binary gas phase reactions, the formation and destruction of NO+ in interstellar space are also discussed.

    Notes: Abstract The24MgH+ (A 1Σ+ −X 1Σ+) molecular lines have been identified in the photospheric spectrum. The rotational excitation temperature determined from the analysis of molecular line intensities of24MgH+ is found to be of the order of 4850 K which corresponds to the photospheric temperature of the Sun. The CNDO/2 dipole moments of24MgH+ for internuclear distance range: (1.3–2.1) Å in theX 1Σ+ state can be approximated byM(R)=4.92+1.33R. Estimations for the spontaneous emission Einstein coefficients (A v′ v″ ) and the absorption oscillator strengths (f v′ v″ ) for the (1, 0), (2, 0), and (2, 1) transitions in theX 1Σ+ state of the24MgH+ ion are also made.
