[The application of holistic nursing in the rehabilitation of occupational pneumoconiosis complicated with chronic obstructive pulmonary disease].

Objective: To investigate the effect of holistic nursing on the rehabilitation of patients with occupational pneumoconiosis complicated with acute exacerbation of chronic obstructive pulmonary disease (COPD) . Methods: In October 2018, from September 2016 to September 2018, 120 pneumoconiosis patients with copd admitted to the occupational disease department of Laigang Hospital attached to Affilated to Shandong First Medical University were selected, according to random number table method is divided into experimental group (60 cases) and control group (60 cases) in the control group given conventional nursing, the experimental group to implement the holistic nursing, before and after the intervention were compared of two groups of patients with disease recognition grade self-management behavior of related parameters of blood gas analysis and lung function changes. Results: Comparison of disease recognition score between the two groups, the experimental group was higher than the control group (P<0.05) . Comparison of scores of self-management behaviors such as diseases medical management, daily life management. Emotion management and so on between the two groups showed that the experimental group was higher than the control group (P<0.05) . Comparison of blood gas analysis indicators between the two groups showed that PaO(2) in the experimental group was higher than that in the control group (P<0.05) . Comparison of pulmonary function indicators between the two groups showed that FEV(1) and FEV(1)/FVC in the experimental group were higher than that in the control group (P<0.05) . Conclusion: Holistic nursing can effectively improve the cognition of pneumoconiosis patients with copd in the acute exacerbation stage, regulate their self-management behavior, improve arterial oxygen content, improve pulmonary ventilation function. and promote the recovery of the disease.

[Clinical abservations of pulmonary surfactant' s autologous transfusion in massive lung lavage].

Objective: Investigate the pulmonary surfactant autotransfusion effect on the recovery of respiratory function in patients with whole lung lavage, to provide theoretical basis for the clinical application. Methods: We taken 30 patients of pneumoconiosis treated by whole lung lavage as the subjects. We extracted the pulmonary surfactant from lavage fluid, after single postoperative lung lavage for the first time; after one weeks when the second times of lung lavage were performed to the other side of the lung of patients, we put PS into the right side. We taken the patients the second times of lung lavage who were put PS into the right side as returning group, the first times of lung lavage who were not put PS into as on returning group. We observed indi-cators, such as expiratory resistance, respiratory work, lung compliance, airway pressure, PO(2), the pulmonary function recovery time and other indicators, comparing with the changes of pulmonary function before lung la-vage for the first time and at 0、60、90、120 min after the pulmonary surfactant autotransfusion. Results: Com-pared with the no returning group, the expiratory resistance of the returning group decreased significantly at 90 min、120 min after the pulmonary surfactant autotransfusion; the respiratory work and airway pressure of the re-turning group decreased significantly at 60、90、120 min after the pulmonary surfactant autotransfusion, there was statistically significant in the difference between different groups (P<0.05, P<0.01). Compared with the no returning group, the lung compliance and the PO(2) of the returning group increased significantly at 60 min、90 min、120 min after the pulmonary surfactant autotransfusion, there was statistically significant in the difference between different groups (P<0.05, P<0.01). The lung function recovery time of returning group was (155.7 ± 35.2) min, the lung function recovery time of no returning group was (183.71±41.81) min, there was statistical-ly significant in the difference between different groups (P<0.05). Compared with the no returning, there were not statistically significant in the difference of the Heart rate、the systolic blood pressure and the diastolic blood pressure about the returning at 60、90、120 min after the pulmonary surfactant autotransfusion.There was no ad-verse reactions such as pulmonary infection, pulmonary infection and so on. Conclusion: The pulmonary surfac-tant autotransfusion may reduce expiratory resistance, work of breathing, airway pressure; improve lung compliance, alveolar ventilation function; increase oxygen partial pressure and decrease the surgery recovery time in patients with pneumoconiosis.

[The effects of foot reflexology on fatigue and insomnia in patients suffering from coal workers' pneumoconiosis].

PURPOSE: The purpose of this study was to determine the effects of foot reflexology on fatigue and insomnia in patients suffering from coal workers' pneumoconiosis. METHOD: This study was a quasi-experimental study of pre-test and post-test design in a non-equivalent control group. The subjects of this study consisted of both the experimental group of twenty-nine and the control group of thirty coal workers' pneumoconiosis patients. Data was collected from December 10, 2002 to February 15, 2003. Foot reflexology was performed for 60 minutes twice a week through five weeks in the experimental group, but none in the control group. To evaluate the effects of foot reflexology, the scores of fatigue and insomnia were measured before and after the experiment in both groups. Fatigue was evaluated by Fatigue Symptoms Inventory. Insomnia was measured with the visual analogue scale (VAS). Data of this experiment was analyzed by Chi-square test, t-test, unpaired t-test and Repeated Measures ANOVA with the SAS Program. RESULTS: The scores of fatigue and insomnia decreased in the experimental group but not in the control group. There was a significant difference of fatigue and insomnia between the two groups. CONCLUSION: It is suggested that foot reflexology might have beneficial effects on reducing fatigue and insomnia in patients suffering from coal workers' pneumoconiosis, and can be recommended as a nursing intervention program for patients with coal workers' pneumoconiosis.

[The correction of the status of the pulmonary surfactant system as a method for preventing experimental pneumoconiosis]. / Korrektsiia sostoianiia surfaktantnoi sistemy legkikh kak metod profilaktiki éksperimental'nogo pnevmokonioza.

Using a model of experimental pneumoconiosis in albino rats, induced by breathing in a rock dust, we attempted correction of the pulmonary surfactant system, for which purpose we tried choline chloride as a drug preparation. The action of the above drug was found out to be depended upon the moment of its administration and time during which it is being administered, and is that of influence on both the concentration and mechanism of absorbtion of surface-active fractions of the surfactant in the liquid-gas interface. Early administration of choline chloride (during the dust factor exposure) increases concentration of those surfactants notable for their surface-active properties being maintained, and improves the processes of diffusion of surface-active substances, which observation is accompanied by decrease in intensity of the processes of fibroformation in the lung tissue. Choline chlorid employed on the discontinuation of the dust exposure has adverse effects leading to changes in the lipid composition, impairing the surface-active properties and processes of diffusion of the pulmonary surfactant, which fact may contribute to aggravation of fibrosis in the lungs.

Mineralogical analysis of the respiratory tract in aluminium oxide-exposed workers.

A retrospective study was conducted in order to characterize the retention of fibrous and nonfibrous mineral particles in the respiratory tract in subjects with previous occupational exposure in the aluminium industry. Bronchoalveolar lavage (BAL) fluid (three samples) or lung parenchyma (two samples) were studied using analytical transmission electron microscopy in five patients. A high concentration of aluminium fibres (> 10(7) fibres.g-1 dry lung) was identified in two lung tissue samples, and aluminium fibres were also identified in BAL fluid in three patients. All fibres were short (mean length: 1-2 microns), with no fibre longer than 5 microns. Some biopersistence of these fibres in the respiratory tract is suggested from these observations, since fibres were identified in biological samples collected more than 4 yrs after cessation of exposure in four out of five patients. Occupational physicians should be aware of possible exposure to short, thin aluminium fibres during primary aluminium production. Further studies are needed to assess the potential health effects of these fibres. Industrial hygiene measurements should also be performed to document the potential sources of exposure to aluminium fibres in this industry.

[Effectiveness of climatic health resort complex treatment of patients with pneumoconiosis and dust-induced bronchitis using underwater massage shower]. / Effektivnost' klimaticheskogo sanatorno-kurortnogo lecheniia bol'nykh pnevmokoniozom i pylevym bronkhitom s vkliucheniem v lechebny kompleks protsedur podvodnogo dusha-massazha.

The article provides the results of studies of 167 cases affected with occupationally-related pneumoconiosis and dust bronchitis. 117 patients were treated with complex resort therapy including under-water massage, and 50 patients were given the same complex therapy without shower massage. The effectiveness of the therapeutic techniques were evaluated basing on both objective and subjective criteria, including supplementary laboratory and functional techniques. The results were positive in both groups, but in the major group, the favourable shifts were more expressed but statistically were not reliable. Thus, the underwater shower massage may be regarded as a positive but not decisive factor in the complex resort treatment of occupational diseases of lungs.

[The use of hyperbaric oxygenation for the treatment of patients with pneumoconiosis and pulmonary heart failure]. / Primenenie giperbaricheskoi oksigenatsii dlia lecheniia bol'nykh pnevmokoniozom s legochno-serdechnoi nedostatochnost'iu.

Examination of 76 patients with pneumoconiosis (stage I) revealed that hyperbaric oxygenation is increasing the force of cardiac contractions, reduction of the general peripheral resistance and reduction of the lesser circulation hypertension. The therapeutic action of hyperbaric oxygenation is related to its ability to remove the sequels of oxygen.

Epidemiologic studies of Scottish oil shale workers: II. Lung function in shale workers' pneumoconiosis.

In a case control study of 122 ex-shale workers, half of whom had simple pneumoconiosis and half of whom did not, those with pneumoconiosis were found to have the poorer lung function. Significant reductions in forced expiratory capacity (FEV1), forced vital capacity (FVC), Vmax50, lung volumes, and carbon monoxide transfer were found in men with pneumoconiosis. It is suggested that these abnormalities may represent a mixture of pulmonary fibrosis and airways obstruction related to exposure to dust and fumes in shale mines and at shale retorts.
