目的:观察呼吸机相关肺炎(VAP)病原菌及其耐药性。方法:回顾分析60例VAP的临床资料、病原菌的构成及其耐药性。结果:60例VAP患者共培养出致病菌126例,其中革兰阴性菌77株,占61.1%,其中以铜绿假单胞菌、大肠埃希菌、鲍曼不动杆菌为主,对多种抗生素耐药。革兰阳性菌18株,占14.3%,以金黄色葡萄球菌最常见;真菌31株,占24.6%,以白色念珠菌为主。结论:VAP病原菌以革兰阴性菌为主,其对多种抗生素耐药严重。临床上应重视病原菌培养和药敏结果,合理应用抗生素。
Objective: To observe the pathogens and their drug resistance of ventilator-associated pneumonia (VAP). Methods: A retrospective analysis of 60 cases of VAP clinical data, the composition of pathogens and drug resistance. Results: Totally 126 pathogenic bacteria were co-cultivated in 60 patients with VAP, of which 77 were Gram-negative bacteria, accounting for 61.1%, of which Pseudomonas aeruginosa, Escherichia coli and Acinetobacter baumannii were the most common Antibiotic resistance. Gram-positive bacteria 18 strains, accounting for 14.3% to Staphylococcus aureus is the most common; 31 strains of fungi, accounting for 24.6%, mainly Candida albicans. Conclusion: Gram-negative bacteria are the main pathogens of VAP and their resistance to many antibiotics is serious. Clinic should pay attention to pathogen culture and susceptibility results, rational use of antibiotics.
