Lung Ultrasound in Pediatric Acute Chest Syndrome

Sickle-cell disease is a common disease with serious complications, in particular acute chest syndrome (ACS), which can be life threatening. The pathophysiology of ACS is poorly understood, but alveolar hypoventilation appears to play an important role. Pulmonary ultrasound is increasingly used in pediatrics to diagnose ACS. The management of ACS is complex, including oxygen therapy, antibiotics, spirometry, transfusions and ventilatory support. ACS and acute vaso-occlusive pain are the main reasons for hospitalisation in pediatric intensive care units. The aim of this study was to identify the pulmonary indicators correlated with ventilation time in these children, and to study the correlations between the results of lung ultrasound (LUS) and the clinical severity of the episode. The inclusion criteria for this study are the presence of an ACS in a child aged between 1 month and 17 years hospitalised in the pediatric intensive care unit at Robert-Debre Hospital who has not expressed any opposition and without opposition from their legal representative. The study will run for 2 years, with a target of 60 patients. Each patient included in the study will have multiple LUS during their care, in accordance with a protocol, and their clinical, biological and radiological data will be collected during their stay in the department.
