Abstract:
OBJECTIVE:To pro vide reference for rational use of antibiotics in pediatric department. METHODS :Clinical bacterial strains isolated from children outpatients and inpatients were collected from West China Guang ’an Hospital of Sichuan University(called“our hospital ”for short )during Jan. 2014 to Jun. 2019. Distribution and drug resistance of bacteria were analyzed retrospectively. RESULTS :During 2014-2019,total of 4 692 strains were detected ,accounting for 29.56% of total ;those were mainly from sputum (3 749 strains,79.90%),blood(203 strains,4.33%)and secretion (137 strains,2.92%)specimen. Among them ,1 488 strains of Gram-positive bacteria (31.71%)were mainly Streptococcus pneumoniae (711 strains,15.15%) and Staphylococcus aureus (574 strains,12.23%);3 204 strains of Gram-negative bacteria (68.29%)were mainly 2 466 strains of Haemophilus influenza (52.56%). Totally 172 strains of methicillin-resistant S. aureus and 1 517 strains of β-lactamase producing H. influenzae were detected ;the detection rates were 29.97% and 61.52% ,respectively. Resistance rates of H. influenza to ampicillin,cefaclor and cefuroxime were higher than 50%,and the overall trend was on the rise ,resistance rates of cefotaxime , rifampin and ofloxacin were all lower than 6%. Resistance rates of S. pneumoniae to erythromycin and tetracycline were more than 70%,and the resistance rate to erythromycin was increasing year by year. Resistance rates of S. pneumoniae to β-lactams and quinolones were generally lower than 20%. No resistant strains of linezolid and vancomycin were found. Resistance rate of S. aureus to penicillin G was more than 90%. S. aureus was relarively sensitive to aminoglycosides ,macrolides and tetracyclines ;no furantoin,linezolid and vancomycin-resistant strains were found. CONCLUSIONS :Gram-negative bacteria are the main pathogens isolated from children in our hospital ,and most of them are H. influenza e,S. pneumon iae and other caustic bacteria. The detection rate of drug-resistant and enzyme producing strains is high , and the resistance rate of several pathogens to commonly used 0826-2600251。E-mail:wenxiaozheng269@sina.com antibiotics is increasing year by year. Drug resistance is severe. In order to delay the emergence and spread of drug-resistant pathogens in real time and further standardize the use of pediatric antibiotics.
