Rationale: Prospective studies that evaluated the outcome of childhood empyema are limited.
Objective: To compare the outcome of pulmonary function in children with empyema.
Patients and methods: Children discharged with a diagnosis of empyema underwent a longitudinal study including measurement of pulmonary function and radiographic imaging.
Results: The population consisted of 39 patients, 24 males, and 15 females; with a median age of 4.6 years. Etiology was defined in 20/39 patients, and predominant microorganism was Streptococcus pneumoniae (19/20 isolates). Chest tube drainage with or without fibrinolytic agents was the primary intervention in 25 children. Video-assisted thoracoscopic surgery was performed in 14 and 5 children as primary and secondary intervention, respectively. Thirty-five children completed the lung function follow-up. At first follow-up visit, 5 out of 17 children able to perform spirometry (initially collaborating children) had normal tests, and 12 had mild-to-moderate defects of lung function that returned to normal over 2-57 months. Eighteen children unable to perform spirometry at first follow-up visit (initially non-collaborating children) had normal tests when they were evaluated 5-78 months postdischarge. At the end of the follow-up, all patients had normal lung function. Time to normalize did not differ between groups receiving different treatments (initially collaborating children, P = 0.064; initially non-collaborating children P = 0.223). Three previously healthy children had recurrent cough, and all children had normal chest radiographs aside from pleural thickening.
Conclusions: The respiratory outcome in children with empyema is generally good and is not influenced by the type of intervention.
