Case PresentationAn 8-month-old previously healthy, full-term girl presented with altered mental status after falling approximately 3 feet from a bed, landing on her head. In the ED, she had a CT scan of her head (Fig 1) and was intubated for airway protection. While in the PICU, initial chest radiography showed bilateral infiltrates that were consistent with ARDS, which subsequently resolved. Her respiratory status continued to improve, which allowed a trial on CPAP with invasive neurally adjusted ventilatory assist (NAVA) support, which she was unable to tolerate because of the need for increased support during sleep. On hospital day 8, she was extubated to noninvasive NAVA and was noted to have poor truncal tone and inability to lift or rotate her head. Repeat head CT scans were unchanged. Despite nasal CPAP and NAVA support, she experienced hypercapnia to 83 mm Hg that required reintubation. Brain MRI was completed on hospital day 10 (Fig 1). Lumbar puncture results were obtained, which were unremarkable. Extubation was attempted again on hospital days 15 and 22 with subsequent hypercapnia that required reintubation. She was able to gradually lengthen her CPAP trials but continued to have periods of hypercapnia and bradypnea.Copyright © 2021 American College of Chest Physicians. Published by Elsevier Inc.
