Outcome of pediatric empyema thoracis managed by tube thoracostomy

The proper management of empyema thoracis in children continues to be a source of debate. This study assessed the clinical profile and outcome of patients managed by tube thoracostomy. Chart review was performed in 31 patients managed from January 1989 to December 2003. Outcome measures were duration and outcome of thoracostomy, number of days to radiologic lung re-expansion, length of hospitalization, and microbiologic flora involved. The mean age was 9 years (male/female, 2:1) and the most commonly affected group were those aged 1 year and below. Staphylococcus aureus was the most frequent infecting organism. A few (6%) achieved lung re-expansion 1 week postoperatively, but 64% did not achieve full lung re-expansion even after 3 weeks. Most (71%) of the thoracostomies were converted to open drainage. Half (52%) of the patients were hospitalized for at least 5 weeks. There were 3 recurrences and 3 deaths, 2 of which were most likely associated with empyema. Empyema managed by tube thoracostomy alone showed evidence of delayed lung re-expansion, prolonged drainage and hospitalization, and unfavorable outcome.
