Management of parapneumonic effusions in pediatrics: current practice

Pleural Thickening after Pleural Effusion: How can we Follow-Up in Children?

INTRODUCTION

No clear information exists about the factors affecting pleural thickening following parapneumonic effusion in children. We aimed to investigate factors that affect the resolving time of pleural thickening after parapneumonic effusion.

METHODS

Between the years of 2007-18, 91 patients, which were followed due to diagnosis of pleural thickening after parapneumonic effusion, were assessed. Ages, complaints, physical examination findings, laboratory results, chest x-ray and ultrasonography findings, treatments, duration of treatment and recovery time of the patients were examined terms in of pleural thickening resolving time.

RESULTS

The mean age of patients was 7.5 ± 5.0 years. Pleural thickening resolving time was 151 ± 6.8 days. The resolving time for pleural thickening was delayed with older ages, longer duration of complaints, fever before hospital admission and treatment, lower oxygen saturation at the time of admission, crackles in the physical examination, higher white blood cell count and pleural fluid density (p = 0.018, p = 0.001, p = 0.021, p = 0.020, p = 0.024, p = 0.025, p = 0.021, p = 0.019). In addition, the amount of effusion measured by thorax ultrasonography, fibrinolytic usage, and complications had a role in the delayed resolving time (p = 0.034, p = 0.001, p = 0.034). Pleural thickening resolved in 80% of the patients.

CONCLUSION

In this report, 80% of pleural thickening, following parapneumonic effusion resolved within 5 months. Patients who do not have a complication during follow-up are not required to monitor with frequent chest x-ray. Patients with a higher amount of pleural effusion, complications and need for fibrinolytic treatment should be followed more carefully.

Seventeen-year study shows rise in parapneumonic effusion and empyema with higher treatment failure after chest tube drainage

AIM

To evaluate epidemiology, pre-admission characteristics and management of paediatric parapneumonic effusions (PPEs) and empyema in a tertiary paediatric pulmonary centre between 1993 and 2010.

METHODS

Retrospective chart review study using paediatric and thoracic database searches, with particular emphasis on pre-admission characteristics, disease stage (simple or complex effusion or empyema), general management and surgical procedures.

RESULTS

One hundred children were eligible, exhibiting a significant increase in incidence from 0.5 to 2.6 per 100 000 across the study period. Baseline characteristics were similar across disease stages. Streptococcus pneumoniae was the most common pathogen. Surgical intervention beyond chest tube drainage (CTD) was required in 50%; this rate showed a particular increase in children aged 0-5 years (OR, 3.1), but was otherwise not influenced by baseline characteristics, disease stage or use of intrapleural fibrinolytics. Length of hospitalisation did not differ across disease stages or primary interventional procedures.

CONCLUSION

This study confirmed an increasing incidence of PPEs and empyema in a Scandinavian tertiary paediatric pulmonary centre. Young children exhibited higher treatment failure after CTD. Length of hospitalisation was similar across disease stages and was comparable to previous reports according to primary interventional procedure.

Current evidence for the management of paediatric parapneumonic effusions

BACKGROUND

Parapneumonic effusions (PPE) and empyema, secondary to bacterial pneumonia, are relatively uncommon but their prevalence is increasing lately. Even if their prognosis is generally good, they may still cause significant morbidity. The traditional treatment of PPE has been intravenous antibiotics and, when necessary, chest tube drainage. Open thoracotomy with decortication has usually been applied in case of failure of the traditional approach. Lately, the use of fibrinolysis and/or video-assisted thoracoscopic surgery (VATS) are utilized in the management of PPE; however, there is still little consensus on the most effective primary treatment.

SCOPE

In this article our goal was to summarize, based on up-to-date evidence, all the management options for PPE available to physicians and weigh the benefits and risks of the most popular ones, in an effort to figure out which one is superior as a first-line approach in children.

FINDINGS

A literature search of randomized and retrospective studies that pinpoint methods of evaluation and treatment of PPE was carried out in Medline and Scopus databases. Chest X-ray, ultrasound as well as microbiology and biochemical characteristics of the pleural fluid will facilitate decision-making. Small uncomplicated effusions resolve with antibiotics alone, larger ones require small-bore chest tube drainage and in case of complicated loculated PPE, fibrinolysis or VATS should be considered. Both methods promote faster drainage, reduce hospital stay and obviate the need for further interventions when used as first-line approach. However, primary treatment with VATS is not advised by the majority of studies as a first choice intervention, unless medical treatment has failed.

CONCLUSION

The main steps in treatment are diagnostic thoracocentesis and imaging, small percutaneous drainage, and considering fibrinolysis in complicated PPE. In case of failure, VATS should be the surgical method to be applied.
