RESUMO
The reversal of lung collapse is one of the challenges of lung injury prevention in pediatric acute respiratory distress syndrome. In this case, lung recruitment maneuver (RM) with positive end-expiratory pressure under computed tomography guidance is the procedure of choice, but cumulative ionizing radiation exposure is a major radiologic concern, especially in infants. Real-time guidance of lung recruitment under bedside lung ultrasound (US) assessment in adults has shown to be an effective procedure for performing RM that avoids ionizing radiation overexposure. We report a case of US-guided lung recruitment procedure applied in an infant with severe acute respiratory distress syndrome and advocate that the lung US-guided RM in infants is a feasible and safe procedure.
