Resumo

A abordagem do derrame pleural parapneumónico complicado, em idade pediátrica, permanece controversa. As opções terapêuticas incluem antibioticoterapia e drenagem pleural contínua, instilação intrapleural de fibrinolíticos, videotoracoscopia e toracotomia com descorticação. O objectivo deste estudo foi rever, avaliar e actualizar a abordagem ao derrame pleural complicado. Procedeu-se à revisão retrospectiva dos processos clínicos das crianças internadas na UPP por derrame pleural complicado entre 1992 e 2003. Foram incluídos 25 doentes, com idade média (±DP): 37,4 (± 37,0) meses, sendo 15/25 (60%) do sexo masculino. A identificação do agente foi possível em 17/25 (68%) casos [S. Aureus 6/17 (35%), St. pneumoniae 5/17 (29%)], no líquido pleural em 16/17 (94%) casos. Todos os doentes realizaram toracocentese e antibioticoterapia sistémica. A drenagem pleural contínua foi instituída em 22/25 (88%) casos com duração média (±DP): 14,2 (± 7,8) dias; em 1 caso houve instilação de fibrinolíticos intrapleurais e em 11/25 (44%) realizou-se toracotomia com descorticação. Um doente foi submetido a videotoracoscopia primária. A duração média de internamento (±DP) foi de 30,4 (± 15,1) dias e não ocorreram óbitos. A experiência do centro é determinante na abordagem escolhida e na rapidez de actuação. Provavelmente ambas influenciam o prognóstico imediato.

Abstract

Pediatric management of complicated pleural effusion (CPE) remains controversial. Different approaches include antibiotics and chest tube drainage alone or the use of fibrinolitics, videothorascoscopy (VTC) and surgical decortication through thoracotomy. The aim of the present study was to review, evaluate and update technical approach to CPE. We retrospectively reviewed the clinical files of children admitted to the Pediatric Respiratory Ward between 1992 and 2003 with the diagnosis of CPE. Twenty-five patients were included [15 male (60%)]. Mean (±SD) age was 37,4 (±37,0) months. Bacteria were identified in 17/25 (68%) [S. aureus in 6/17 (35%), St. pneumoniae in 5/17 (29%)], 16/17 (94%)in the pleural fluid. Twenty-five children were treated with antibiotics and thoracocentesis (100%). Chest tube drainage was required in 22/25 (88%) with mean (±DP) duration of 14,2 (±7,8) days. Fibrinolitics were employed in 1 only case and surgical decortication in 11/25 (44%). One patient (4%) was submitted to primary VTC. Median length of stay was 30,4 (±15,1) days and no deaths were recorded. Center skills in CPE management are critical on the choice of the technique and the timing of approach. This seems to influence immediate prognosis.

Key-words: Pleural effusion, pleural empyema, child.
