对20例老年和14例中青年绿脓假单胞菌肺炎患者的临床资料进行对比分析，结果显示：老年组病死率及治疗无效率在各类细菌感染中仍属最高；其病情常进行性加重，较中青年组预后差（P＜0．05）。对于有严重基础疾患、出现严重呼吸困难的老年肺炎患者，应及早作细菌学检查，以确定是否有绿脓假单胞菌感染，而不宜仅凭咳痰颜色判断；丁胺卡那霉素、氧呱嗪青霉素等治疗仍有良好效果，但需联合用药，同时还必须采取其他综合性治疗措施。
The clinical data of 20 elderly patients and 14 middle-aged and young patients with Pseudomonas aeruginosa pneumonia were compared and analyzed. The results showed that the mortality and treatment inefficiency in elderly patients were still the highest in all kinds of bacterial infections; Aggravated, compared with the poor prognosis of young group (P <0.05). For patients with severe underlying diseases and elderly patients with severe pneumonia who have severe respiratory distress, bacteriological examination should be conducted as soon as possible to determine whether there is Pseudomonas aeruginosa infection and not only based on the color of sputum. Amikacin, Oxychlorine and other penicillin treatment is still good results, but the need for combination therapy, but also must take other comprehensive treatment.
