Abstract:
Objective To investigate the types ,specimen types ,department distribution and drug resistance of multi‐drug resist‐ant bacteria in our hospital during the recent 5 years to provide the scientific guidance for the clinical treatment ,prevention and con‐trol of multi‐drug resistant bacteria .Methods The specimens of laboratory bacterial culture positive during 2011-2015 were col‐lected ,and analyzed on the types ,proportion and drug resistance situation of multi‐drug resistant bacteria and their distribution in clinical specimens and clinical departments .Results A total of 2 568 strains of multi‐drug resistant bacteria were isolated and ac‐counted for 37 .41% the positive specimens ,in which top 5 bacteria were Escherichia coli ,Acinetobacter baumannii ,Staphylococcus aureus ,Klebsiella pneumoniae and Pseudomonas aeruginosa;the sputum ,midstream urine ,blood and secretions had the higher posi‐tive rate of multi‐drug resistant bacteria ,while the secretions from the catheter tip and ear discharge had the lower positive rate(P<0 .05);the multi‐drug resistant bacteria had difference among different departments ,in which ICU ,respiratory department and sur‐gery department were highest ,while the lowest was in the spleen and stomach department and breast department ;the resistance of multi‐drug resistant bacteria occurred over a wide range ,which had higher resistance to beta lactam and aminoglycosides and had higher sensitivity to compound antibacterial drugs such as sulfamethoxazole antibiotics and enzyme inhibitors .Conclusion Multi‐drug resistant bacteria are more and more common in clinic .The positive rate is increased year by year .The drug resistant strains widely distributed .The clinical departments should pay high attention to .Rational and scientific use of antibacterial drugs ,strict control of multi‐drug resistant bacterial spread and strength of the patients′isolation have an important significance to effectively prevent and control the multi‐drug resistant bacterial spread .
