  The oxygen concentrator is a suitable alternative to oxygen cylinders in Nepal

  摘要：

  Purpose: To review the efficacy and reliability of oxygen concentrators used over the last six years in Nepal. The apparatus used was a DeVilbiss(R) oxygen concentrator that provided O-2 for anesthesia supplemented with compressed air to drive a Penlon Manley Multivent Ventilator(R). It remains difficult to supply oxygen in cylinders to peripheral hospitals in Nepal due to lack of proper roads.Methods: We conducted a retrospective analysis of a sample of 378 cases anesthetized at the Bir Hospital and at a private hospital in Kathmandu from April through October 1999. The Bain circuit or its modification was used in adults, and Bain or Ayre's T piece in children. High flows from the oxygen concentrator used with the Bain and Ayre's T circuits were reduced to 2 L(.)min(-1), delivered through the halothane vaporizer, supplemented by room air in the modified Bain circuit. Positive pressure ventilation was provided with an Ambubag, Oxford Inflating Bellows or Penlon Manley Multivent Ventilator. Blood pressure, electrocardiogram, FiO(2) and SpO(2) were monitored in all cases.Results: Surgery included urologic, general surgery, obstetrics and gynecological procedures, neurosurgery and closed mitral valvotomy. Age ranged from six months to 78 yr. The anesthetic time lasted from 45 min to 12 hr. The FiO(2) ranged from 0.5 to 0.6 in the Bain and Ayre's T circuits, and from 0.34 to 0.40 in the modified Bain circuit with a flow of oxygen of 2 L(.)min(-1) from the concentratorConclusion: With regular maintenance and servicing done locally, the oxygen concentrator can be used safely in adults and children. Use of the oxygen concentrator is a suitable alternative to oxygen cylinders in the developing world.

  Pulsed electron nuclear double resonance (ENDOR) spectra have been obtained for the exchangeable Mo-OH proton of the low-pH form of native chicken liver sulfite oxidase (SO) and recombinant human SO for the first time. The spectra of the two enzymes are very similar, indicating a similar binding geometry of the hydroxyl ligand to the Mo center. The isotropic hyperfine interaction (hfi) constant for the proton of the OH ligand in both enzymes is about 26 MHz. The anisotropic components of the hfi obtained from the pulsed ENDOR spectra are about 1.6-1.8 times larger than those obtained by continuous-wave electron paramagnetic resonance and electron spin echo envelope modulation. These hfi differences are explained by a rotational disorder of the Mo-OH group. A similar rotational disorder of the coordinated exchangeable ligand has been found previously for the high-pH and phosphate-inhibited forms of SO.
