不同影像特征的煤工尘肺患者院内获得性支气管—肺感染发热症状的分布

Distribution of Hospital-Acquired Bronchus-Pulmonary Infection among the Coalminers' Pneumoconiosis Patients with Different Image Feature

目的了解煤工尘肺不同影像学特征对院内获得性支气管—肺感染(HAPI)临床症状发热的影响。方法采用回顾性的研究方法,观察HAPI在不同小阴影类型及尘肺期别中临床症状发热的分布特点。结果类圆形小阴影、不规则小阴影类型煤工尘肺(CWP)患者,发生HAPI时,出现发热临床症状的分布比较,差异无统计学意义,P>0.05;相同期别(Ⅰ期)CWP中,P阴影出现发热临床症状的发生率高于s阴影,P<0.05;而在Ⅱ期CWP中,u阴影出现发热临床症状的发生率分别高于q、t阴影,P<0.05;不同期别CWP患者,发生HAPI时,出现发热临床症状的分布两两间比较差异无统计学意义,均P>0.05;相同小阴影类型(q阴影)CWP中,不同尘肺期别出现发热临床症状分布两两间比较差异无统计学意义,均P>0.05。结论不同小阴影类型的CWP患者,发生HAPI时,其发热发生率有差异,在Ⅰ期CWP中,P阴影出现发热临床症状的发生率高于s阴影,在Ⅱ期CWP中,u阴影出现发热临床症状的发生率高于q,t阴影;没有观察到不同尘肺期别的CWP患者,发生HAPI时,对发热发生率有影响。

[ Objective] To learn the effect of different image features of eoalminers＇pneumoeoniosis on the clinical symptoms of hospital - acquired bronchus - pulmonary infection. [ Methods] Retrospective study was conducted to observe the different HAPI images and the distribution of clinical symptoms of pneumoconiosis. [ Results ] No significant difference was found between the CWP patients with round-like small image and irregular small image in the clinical fever symptoms of HAPI （ P 〉 0.05 ） ; among the CWP of grade I, the incidence of clinical fever of the P image was higher than that of S image （ P 〈0.05 ） ; in grade II of CWP, the inci- dence of clinical fever of U image was higher than that of the Q and T image（ P 〈0.05 ） ; no significant difference was found between different grades of CWP （ P 〉 0.05） ; [ Conclusion ] Different HAPI images of CWP patients were not found to have any effect on the incidence of clinical fever when having HAPI.
