Impact of chest x-ray before discharge in asymptomatic children after cardiac surgery-prospective evaluation


Quandt, Daniel; Knirsch, Walter; Niesse, Oliver; Schraner, Thomas; Dave, Hitendu; Kretschmar, Oliver (2013). Impact of chest x-ray before discharge in asymptomatic children after cardiac surgery-prospective evaluation. Pediatric Cardiology, 34(1):155-158.

Abstract

In many paediatric cardiac units chest radiographs are performed routinely before discharge after cardiac surgery. These radiographs contribute to radiation exposure. To evaluate the diagnostic impact of routine chest X-rays before discharge in children undergoing open heart surgery and to analyze certain risk factors predicting pathologic findings. This was a prospective (6 months) single-centre observational clinical study. One hundred twenty-eight consecutive children undergoing heart surgery underwent biplane chest X-ray at a mean of 13 days after surgery. Pathologic findings on chest X-rays were defined as infiltrate, atelectasis, pleural effusion, pneumothorax, or signs of fluid overload. One hundred nine asymptomatic children were included in the final analysis. Risk factors, such as age, corrective versus palliative surgery, reoperation, sternotomy versus lateral thoracotomy, and relevant pulmonary events during postoperative paediatric intensive care unit (PICU) stay, were analysed. In only 5.5 % (6 of 109) of these asymptomatic patients were pathologic findings on routine chest X-ray before discharge found. In only three of these cases (50 %), subsequent noninvasive medical intervention (increasing diuretics) was needed. All six patients had relevant pulmonary events during their PICU stay. Risk factor analysis showed only pulmonary complications during PICU stay to be significantly associated (p = 0.005) with pathologic X-ray findings. Routine chest radiographs before discharge after cardiac surgery can be omitted in asymptomatic children with an uneventful and straightforward perioperative course. Chest radiographs before discharge are warrantable if pulmonary complications did occur during their PICU stay, as this is a risk factor for pathologic findings in chest X-rays before discharge.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
