Retrospective study of empyema cases in National Pediatric Hospital, Cambodia.

ABSTRACT

Majority of empyema cases admitted into the National Pediatric Hospital (NPH), Cambodia were of bacterial origin (EB 95%), the rest were caused by tuberculosis bacilli (ETB 5%). The morbidity of overall empyema, empyema of bacterial origin and empyema of TB origin between boys and girls was the same, even though boys were more likely to be exposed than girls. The mean age of patients with ETB was significantly greater than those of EB, 84.7 +/- 46 months versus 52.5 +/- 37 months. Since NPH is located in Phnom Penh, most of our cases were from Kandal, Phnom Penh, and provinces nearby. On average all of the patients stayed in the hospital for 23.26 +/- 14.9 days (rank 1-91 days), and the mean duration of hospitalization of the ETB patients was significantly longer than that of EB patients, 32 +/- 19 days versus 22 +/- 14 days respectirely. The yearly incidence of empyema cases in 1990-1993 had the trend of slightly increased frequency during March to May. The overall EB case fatality rate was 3%, contributed to by delayed referral of cases.
