摘要
目的:探讨呼吸机相关性肺炎(VAP)患者病原菌分布及耐药性,以指导临床防治提供依据。方法:收集VAP患者下呼吸道分泌物进行细菌培养及药物敏感试验分析。结果:从vAP患者下呼吸道分泌物中分离出134株病原菌,以革兰阴性杆菌为主(94/134)70.15%,且呈多药耐药性;对派拉西林、头孢他啶、头孢噻肟等药物耐药,其耐药率在72.72%以上,革兰阳性球菌占(24/134)17.91%,分离的葡萄球菌均为耐苯唑西林葡萄球菌(MKS);对青霉素、头孢唑啉耐药率〉80.00%,对大部分抗菌药耐药,对万古霉素高度敏感;分离出的真菌占(16/134)11.94%。结论:vAP患者的病原菌以革兰阴性杆菌为主,其次是革兰阳性球菌,且耐药现象严重,应加强VAP患者预防控制,缩短机械通气,合理使用抗菌药。
Objective: To investigate the distribution and drug resistance of pathogens in patients with ventilator associated pneumonia (VAP) in order to provide evidence for clinical prevention and treatment. Methods: the bacterial culture and drug sen- sitivity test of lower respiratory tract secretions from patients with VAP were collected and analyzed. Results: 134 strains of pathogenic bacteria were isolated from lower respiratory tract secretions of VAP patients, dominated by Gram negative bacilli (94/ 134, 70.15%) , and showed multi drug resistance; They wereresistant to piperacillin, ceftazidime ceftazidime, and cefotaxime, with the resistance rate at more than 72.72%. Gram positive cocci accounted for (24/134, 17.91%) , Isolated Staphylococcus was resistant to oxacillin (MRS) ; They were resistant to pemcillin and cefazolin, with the resistant rate 〉80.00%. They were resistant to most an- timicrobial drugs and highly sensitive to vancomycin;Isolated fungi accounted for 11.94% (16/134) . Conclusion: The pathogenic bacteria in VAP patients were mainly gram-negative bacilli, followed by Gram positive bacteria, with serious drug resistance. We should strengthen the prevention and control of VAP patients, shorten the mechanical ventilation, and use antimicrobial agents ratio- nally.
