目的研究纤维支气管镜检查与院内感染关系。方法将住院病人胸部Ｘ线（正侧位）表现为肺部块影而待进一步明确诊断的病例按照随机原则分成Ａ、Ｂ两组。Ａ组９２例全部行纤维支气管镜检查（活检和刷检），Ｂ组８７例做ＣＴ或ＭＲＩ检查作为对照组，两组病例全部进行院内感染综合性指标监测。结果Ａ组出现发热２４例，其中高热５例，血培养（＋）２例，痰普通培养（＋）５例，痰霉菌培养（＋）２例，血象升高８例，肺部出现新浸润灶８例。Ｂ组发热５例，肺部新浸润病灶２例，血、痰培养（－）。Ａ、Ｂ两组发热及肺部浸润病灶例数比较，差异皆有显著性（Ｐ＜０．０１，Ｐ＜０．０５）。结论纤支镜检查与院内感染有明显相关性。
Objective To study the relationship between bronchoscopy and nosocomial infection. Methods The inpatients chest X-ray (posterior lateral) showed pulmonary block shadow and to be further clear diagnosis of cases according to the random principle is divided into A, B two groups. A group of 92 patients underwent all bronchoscopy (biopsy and brush examination), B group of 87 patients underwent CT or MRI as a control group, the two groups of patients with comprehensive monitoring of nosocomial infections. Results There were 24 cases of fever in group A, including 5 cases of hyperpyrexia, 2 cases of blood culture (+), 5 cases of sputum common culture (+), 2 cases of sputum mold culture (+), 8 cases of blood hyperplasia, 8 cases stove. B group fever in 5 cases, pulmonary infiltration in 2 cases, blood, sputum culture (-). There were significant differences in the number of cases of fever and pulmonary infiltrates between groups A and B (P <0.01, P <0.05). Conclusion There are obvious correlation between bronchoscopy and nosocomial infection.
