Abstract:
BACKGROUND: Atelectasis is a state of a collapsed and non-aerated region of the lung parenchyma, which is otherwise normal. This condition is usually associated with pulmonary disorders. The purpose of this study is to analyze the incidence and risk factors of atelectasis in patients admitted to the pediatric intensive care unit (PICU). METHODS: We retrospectively analyzed the clinical characteristics and chest radiography of 280 PICU patients under 18 years old. We analyzed the incidence and pattern of atelectasis and compared the incidence according to the phase and mode of mechanical ventilation. We compared the incidence of ventilator care need and respiratory disease in 93 atelectasis patients. RESULTS: Atelectasis incidence was 33.2%. The age (4.9 +/- 4.4 years) was younger and the admission-duration (17.8 +/- 25.1 days) was significantly longer in atelectasis patients (p < 0.01). Ventilator care need and respiratory disease in atelectasis patients (86.0%, 66.7% respectively) was significantly higher than in non-atelectasis patients (62.6%, 43.3% respectively) (p < 0.01). Atelectasis incidence in ventilator-required patients and respiratory-diagnosed patients (40.6%, 43.4% respectively) was significantly higher than that in non ventilator-required patients and non respiratory-diagnosed patients (15.7%, 22.6% respectively) (p < 0.01). Atelectasis was more common in the right upper lobe (55.6%) and during or after ventilator care (62.6%) (p < 0.05). Atelectasis incidence in ventilator care did not differ between the assist-control and intermittent mandatory ventilation modes. CONCLUSIONS: In the PICU, atelectasis incidence was higher in patients with ventilator care and respiratory disease. Atelectasis was more common in the right upper lobe and in the phase after ventilator initiation. Atelectasis incidence in ventilator care did not differ between ventilation modes.
