[目的]探讨老年肺癌患者伴发呼吸道感染的病原菌及耐药情况。[方法]回顾性调查分析126例老年肺癌患者呼吸道感染痰培养及药敏试验的临床资料。[结果]共送痰培养检测203次,培养出病原菌26种118株,其中细菌89株,真菌29株;革兰阴性菌70例次占78.7%,革兰阳性菌19例次占21.3%。[结论]老年肺癌患者的呼吸道感染病菌多为革兰阴性菌,常用抗生素耐药明显。临床医生应勤做痰培养,合理使用抗生素,防止药物滥用致细菌耐药引起难治性感染。
[Objective] To investigate the pathogens and drug resistance of respiratory tract infections in elderly patients with lung cancer. [Methods] The clinical data of 126 sputum cultures and drug susceptibility tests of respiratory tract infection in elderly lung cancer patients were retrospectively analyzed. [Result] Totally 203 sputum culture tests were carried out, of which 26 strains and 118 strains were cultured, of which 89 were bacteria and 29 were fungi. Gram-negative bacteria accounted for 78.7% of gram-negative bacteria and 19 gram-positive bacteria, accounting for 21.3%. [Conclusion] The majority of respiratory tract infections in elderly patients with lung cancer are Gram-negative bacteria, and antibiotic resistance is obvious. Clinicians should do Qin sputum culture, the rational use of antibiotics to prevent drug abuse caused by bacterial resistance refractory infections.
