Abstract

|
Febrile diseases were frequently experienced in the pediatric fields, in which 6-10% was bacteremia patients. It was invaded in any organ by blood stream, resulting in meningitis, pneumonia, empyema etc, also serious disease causing high mortality. In these reasons, early detection and treatment of any pediatric patients suspected of having bacteremia must be initiated as rapidly as possible.
Present study was carried out to early detection of baeteremia, performed white blood cell (WBC) count, differential count, blood culture, in the 507 cases of upper 38°C febrile diseases who were admitted to the department of pediatrics of Korea University Hospital during the period of 21/2 years from September 1983 to December 1985 were studied.
Results obtained were as follows:
1. Sex ratio male to female in 507 patients were 2:1, which bacteremia were 60 cases (12%) and sex ratio male to female was 1.4:1.
The highest age incidence was in the age more than 24 months (246 cases, 49%), next was under 6 months (115cases, 23%). Among 60 bacteremic patients, highest age incidence was in the age under 6 months (24 cases, 40%).
2. Individual test of 60 bacteremic patients among 507 patients for WBC>15,000/mL, band cell>500/mL, seg. cell>10,000/mL, PMNs>10,500/mL and 3/4 test (more than 3 abnormalities) was performed and found WBC>15,000/mL, 3/4 test only significant for early detection of bactermia (p<0.05).
3. The causative organism of 60 cases of bacteremia, 41 cases (68%) were gram positive, in which staphylococcus (27 cases) was most common organism and 29 cases (32%) were gram negative, in which salmonella sp. (8 cases) was most common.
4. The most common associated disease was meningitis (8 cases, 21%) and gastroenteritis and skin infection were the next.
5. Average temperature in associated with focal disease was 38°9C, not associated case was 38°8C, in negative on blood culture was 38°C.
