Abstract:
Objective To analyze the etiological results and clinical characteristics in infants with acute pneumonia at the age of 0 ～ 1 years and to evaluate the rationality of the use of antibiotics.Methods Thirty-four infants hospitalized during Dec 2010 to Nov 2012 were selected.The throat swabs were sent to the Beijing Disease Prevention and Control Center for rapid nucleic acid test for influenza; the sputum was sent to the bacteriological laboratory of the hospital for the bacterial culture.Children drug utilization index (cDUI)was used to assess the rationality of the medication amount of antibiotic drugs.For defined daily dose statistic (DDDs),the larger the value of DDDs,the more frequent the clinical use of the drug.Results In the confirmed cases of acute pneumonia,21 cases were of viral infection,9cases were of bacterial infection and 4 cases were of mixed infection.The probability of bacterial pneumonia (4/9) was higher than that of viral pneumonia(5/21) in the case with underlying disease (P ＜0.001) ;the virus detection rate(12/21) of children with contact history with respiratory tract infection patients was higher than bacteria detection rate(4/9)(P =0.01).In case of no risk of cross infection,the infants were more susceptible to bacterial infection (P =0.006).The sputum culture of 25 cases of positive virus detection showed 13 cases of colonization of conditional pathogenic bacteria and 4 cases of pathogenic bacteria.The ratio of combination use of antibiotic drugs in case of bacterial infection (4/9) was higher than that in mixed infection (1/4) (P =0.001).The durations of the use of antibiotic drugs for every group showed no statistical difference (P =0.29).This research involved 7 antibiotic drugs.The medication frequencies and durations of ceftriaxone (DDDs =1813.45,total medication duration =187 days) and cefuroxirne (DDDs =1513.73,total medication duration =162 days) were higher than those of the other 5 antibiotic drugs.The cDUI of all drugs ≤ 1.0.The decreasing order of drugs by cDUI was amoxicillin and clavulanate potassium (cDUI =1.0),cefuroxime (cDUI=0.89),ceftriaxone (cDUI =0.87),azithromycin oral agent and cefepime (cDUI =0.80),midecamycin oral agent (cDUI =0.75) and penicillin injections (cDUI =0.50).Conclusion Virus is the main pathogen of the acute pneumonia in children in this research.Virus provides preliminary conditions for bacterial colonization.The overuse of ceftriaxone aggravates the pathogenic risks of conditional pathogenic virus.Some children are treated by antibiotic drugs for a long time or by the combination use of drugs,which are irrational mediation.
