Etiology, diagnosis, and treatment in childhood atelectasis

Abstract

Introduction: Atelectasis is the loss of lung volume secondary to collapse. Narrow and collapsible airways and underlying chronic diseases facilitate the development of atelectasis in children. Since atelectasis is an important cause of morbidity and mortality in children, early diagnosis and treatment are of great importance. Methods: Thirty-six patients who were followed up in the pediatric service and pediatric intensive care unit of our clinic be - tween December 1, 2018, and June 1, 2019, and were diagnosed radiologically with atelectasis were evaluated retrospectively. Results: The median age was 1.85 years (1.0–7.37). The most common cause for hospitalization was pneumonia (n=30, 83%). Except for two patients, all patients had an underlying disease that increased the risk of atelectasis. Neurological diseases were the most common diseases among the underlying diseases (n=12, 36%). For the treatment, 4 (11.1%) patients received chest physiotherapy, 19 (52.7%) patients received nebulized medications, and chest physiotherapy, and 13 (36.1%) patients received positive end-expiratory pressure support in addition to these treatments. The frequency of atelectasis in more than one localization was higher in children with the neurological disease than in other patients (n=7, [54%] vs. n=3, [13%]; p=0.018). In patients with atelectasis in more than one localization, the duration of hospitalization was longer (median 12.5 days [9.5–16.75] vs. 19 days [13–22.75]; p=0.034). Discussion and Conclusion: Atelectasis is common in hospitalized children with an underlying disease. In the presence of pathological respiratory symptoms and signs, atelectasis should be kept in mind, and treatment should be started early.
