摘要
目的探讨呼吸机相关性肺炎(VAP)发病原因、病理基础、X线诊断与临床的相关性。方法对25例VAP患者X线表现进行回顾并对照临床资料进行分析。结果25例均出现VAP不同临床症状和体征,X线表现为斑点浸润阴影及大片渗出灶,部分病灶呈肺脓肿或炎性假瘤改变,抗菌治疗后完全吸收15例,明显消散10例。结论发病原因为机械通气后多种诱发因素引起病原菌感染,病理基础是炎性渗出性病变,胸部X线表现无特殊性,诊断本病需密切结合临床病史。
Objeetlve To explore the etiology, basic pathology, X-ray diagnosis of ventilator associated pneumonia（VAP）, and it＇s clinical relevance. Methods The X-ray images and clinical records of 25 patients with VAP were analyzed retrospectively. Results Various kinds of symptoms and signs occurred in the 25 patients with VAP. X-ray images showed small dots, patches and multiple patches with blurred border. Pulmonary abscess or inflammatory pseudotumor could be found in some of the foci. After antibacterial treatment, complete absorption occurred in 15 cases, obvious dissipation in 10. Conclusion The etiology of VAP is pathogenic bacteria infection after mechanical ventilation resulting from multiple susceptible factors. The basic pathology is inflammatory exudative lesion, but no characteristic features on X-ray images. The X-ray diagnosis of VAP should be carried out bv combining with clinical documents.
