Abstract

Abstract: Background: There is limited data describing the characteristics of paediatric post-operative cardiac surgery patients who develop pneumothoraces after chest tube removal. Patient management after chest tube removal is not standardised across paediatric cardiac surgery programmes. The purposes of this study were to describe the frequency of pneumothorax after chest tube removal in paediatric post-operative cardiac surgical patients and to describe the patient and clinical characteristics of those patients who developed a clinically significant pneumothorax requiring intervention. Methods: A single-institution retrospective descriptive study (1 January, 2010–31 December, 2018) was utilised to review 11, 651 paediatric post-operative cardiac surgical patients from newborn to 18 years old. Results: Twenty-five patients were diagnosed with a pneumothorax by chest radiograph following chest tube removal (0.2%). Of these 25 patients, 15 (1.6%) had a clinically significant pneumothorax and 8 (53%) did not demonstrate a change in baseline clinical status or require an increase in supplemental oxygen, 14 (93%) required an intervention, 9 (60%) were <1 year of age, 4 (27%) had single-ventricle physiology, and 5 (33%) had other non-cardiac anomalies/genetic syndromes. Conclusions: In our cohort of patients, we confirmed the incidence of pneumothorax after chest tube removal is low in paediatric post-operative cardiac surgery patients. This population does not always exhibit changes in clinical status despite having clinically significant pneumothoraces. We suggest the development of criteria, based on clinical characteristics, for patients who are at increased risk of developing a pneumothorax and would require a routine chest radiograph following chest tube removal.
