目的研究住院患者鲍曼不动杆菌医院感染的临床分布及耐药性,为提出有效防控策略提供依据。方法通过回顾性分析,对某医院住院患者送检标本分离的鲍曼不动杆菌检验结果进行调查与分析。结果该医院2年时间内,从住院患者送检标本中共分离出鲍曼不动杆菌66株,主要分离自病人痰标本,构成比为81.82%。鲍曼不动杆菌感染标本主要来自重症监护病房,构成比占69.70%。临床分离的鲍曼不动杆菌对阿米卡星和头孢哌酮/舒巴坦尚比较敏感,但对氨苄西林和头孢替坦耐药率达到88.0%~100%。结论该医院鲍曼不动杆菌感染患者主要分布在ICU,痰标本分离率最高,其耐药率呈上升趋势。
Objective To study the clinical distribution and drug resistance of Acinetobacter baumannii inpatients with nosocomial infection and provide evidence for effective prevention and control strategies. Methods Through retrospective analysis, the Acinetobacter baumannii test results of hospitalized patients seized in a hospital were investigated and analyzed. Results During the 2 years, 66 strains of Acinetobacter baumannii were isolated from inpatients, which were mainly isolated from the sputum of patients. The constituent ratio was 81.82%. Acinetobacter baumannii infection mainly from intensive care unit, accounting for 69.70%. Acinetobacter baumannii was more sensitive to cefoperazone / sulbactam, but the drug resistance rate to ampicillin and cefotetan reached 88.0% -100%. Conclusion Acinetobacter baumannii infection in this hospital mainly distributes in the ICU. The sputum specimens have the highest separation rate and the drug resistance rate is on the rise.
