烧伤科患者感染病原菌调查及药敏分析

Pathogens causing infections in burn department patients and analysis of drug susceptibility

目的对烧伤科患者感染病原菌分布及药敏试验进行调查,探讨相应的消毒隔离措施,以期降低烧伤科患者感染风险。方法对烧伤科医护人员动态手指菌、清创室及病区的设施设备、清创室及病区空气等取样进行病原菌培养检测,并对致病菌进行药敏试验,根据检测结果,探讨烧伤科降低微生物污染的风险措施。结果烧伤科、清创室空气、关键设备器械表面、医护人员手指菌、病区空气等共取样126份,均进行微生物培养,分离出15种689株病原菌,其中金黄色葡萄球菌检出145株占21.0%、铜绿假单胞菌112株占16.3%、鲍氏不动杆菌103株占14.9%、真菌78株占11.3%,其他病原菌为表皮葡萄球菌、肺炎克雷伯菌、溶血性葡萄球菌、阴沟肠杆菌等;医护人员手指菌的阳性检出率最高为56.3%,其次为空气中微生物超标率为41.5%;金黄色葡萄球菌对万古霉素敏感性高,对其他抗菌药物有较高的耐药性,铜绿假单胞菌对氨曲南和亚胺培南较为敏感,对其他抗菌药物敏感性差,鲍氏不动杆菌的耐药性普遍较强,肺炎克雷伯菌、阴沟杆菌等对亚胺培南均具有较好的药敏性。结论加强烧伤科医护人员无菌意识的培养、采取措施提高清创室及病区空气质量是降低烧伤科病原菌检出率的重要措施,应引起烧伤科医护人员的重视。

OBJECTIVE To investigate the distribution of pathogens causing infections in the burn department patients, analyze the drug susceptibility and explore corresponding disinfection and isolation measures so as to reduce the risk of infections. METHODS Medical personnel dynamic finger bacteria, the operating room and equipment, and air samples were taken for bacteriology culture detection, the pathogenic bacteria were tested for antibacterial resistance. According to the test results, this paper discussed measures to try to reduce the risk of microbial contamination. RESULTS From burn department, debridement room air, key equipment instrument surface, health care workers fingers and ward air, 126 sample were taken, microbial cultures were performed, separating out 15 kinds of 689 strains of pathogenic bacteria, of which 145 strains of Staphylococcus aureus , accounting for 21.0%, 112 strains of Pseudomonas aeruginosa, accounting for 16.3%, 103 strains of Acineto- bacter baurnannii accounting for 14. 95%,78 strains of fungi, accounting for 11. 3%, other pathogenic bacterias were Staphylococcus e pidermid is , K lebsiella pneumoniae , Staphylococcus haernol yticus , Enterobacter cloacae, etc. Medical personnel finger bacteria had the highest positive detection rate for 56. 3~, followed by microorganisms in the air which was 41.5%. S. aureus to vancomycin sensitivity was high, to other antimicrobial agents had higher resistance, P. aeruginosa for actreonam and imipenem, was more sensitive, the drug resistance of Acinetobacter was generally strong, K. pneumoniae and E. cloaca had good drug sensitivity to imipenem. CONCLUSION To strengthen the cultivation of sterile consciousness of acute medical staff, and take measures to improve the quality of debridement room and ward room is one of the most important measures to reduce the rate of acute bacterial infection.
