This preliminary study was designed to investigate the ability of multiple axial volume three-dimensional fourier transform (3DFT) time-of-flight (TOF) magnetic resonance angiography (MRA) to depict the carotid bifurcation in the early post-carotid endarterectomy period. Five patients underwent intra-operative digital subtraction angiography (DSA) and carotid MRA within 5 days of carotid endarterectomy. An axial volume fast imaging in steady-state precession (FISP) gradient-echo 3DFT TOF carotid MRA technique in this limited series appeared to display accurately the surgically significant abnormalities at the carotid bifurcation after endarterectomy. However, in normal or near-normal intra-operative DSA studies, overestimation of internal carotid artery stenoses was encountered. Postoperative MRA demonstrates potential as a useful non-invasive investigation after carotid endarterectomy but should be interpreted with caution until larger studies become available. 相似文献

An original method is proposed for treatment of long-standing intractable wounds and trophic ulcers using viable cryopreserved allodermotransplants and a distant air-plasma treatment. The main source of the allodermotransplants is the cadaverous skin. It was shown that the cadaverous skin taken during 17 hours after the donor's death was viable. The maximum period for storage of the viable skin when the worked out preservative is used at the temperature regimen -18 degrees C is 10 days, and at -70 degrees C it can be as long as 45 days. The analysis performed included 101 patients with long-standing intractable wounds and trophic ulcers. In 51 of them the new worked out method was used. An analysis of clinical and histomorphological data has proved that the application of the viable cryopreserved allodermotransplants and distant air-plasma treatment favor the better course of reparative processes. By the end of the forth week the wounds were completely closed in 19.7% of patients, the wound areas were considerably less (more than by 50% of the initial size) in 43.1%, less reduction of the wound area (less than 50% of the initial size) in 27.4%, in 9.8% there was no effect. No negative results were noted. It should be noted that closure of the tissue defect can be achieved by stimulation of the physiological regeneration of the patient's tissues. This method of regeneration of the skin is effective in trophic ulcers, long-standing intractable wounds and is also recommended in case of deficit of donor resources or when the severe state of the patient does not allow active surgical treatment. 相似文献

Psychophysiologic indices in evaluation of working capacity,fatigue and overstrain in seamen 总被引:1,自引:0,他引:1

The authors have discussed the new conceptual neurophysiological model of genesis and pathogenesis of fatigue and overstrain in seamen. The complex phase character of the developing changes was revealed. Use of the complex of psychophysiological methods with consideration of neurophysiological nature of the changes detected allowed us to obtain the objective assessment concerning fatigue and overstrain in seamen. It is shown that the existing conceptions about the dynamics of nervous processes developed in seamen during fatigue and overstrain including those described in the corresponding documents of the Navy and their evaluation are too simplified and theoretically incorrect. These incorrect concepts practically prevent the conduction of appropriate medical and prophylactic measures, complicate the standardization of some characteristics of habitability of the Navy ships and submarines, not ensure trouble-free conditions at sea in terms of human factor. 相似文献

Nurses' perceived barriers to the implementation of a Fall Prevention Clinical Practice Guideline in Singapore hospitals 总被引:1,自引:0,他引:1

Background
Theories of behavior change indicate that an analysis of barriers to change is helpful when trying to influence professional practice. The aim of this study was to assess the perceived barriers to practice change by eliciting nurses' opinions with regard to barriers to, and facilitators of, implementation of a Fall Prevention clinical practice guideline in five acute care hospitals in Singapore. 相似文献50.
