Insights
A pediatric fall resulted in altered mental status and respiratory distress, requiring mechanical ventilation. Persistent hypercapnia and poor tone suggested a potential neurological complication following the head injury.
Area of Science:
- Pediatric Neurology
- Critical Care Medicine
- Traumatic Brain Injury
Background:
- A previously healthy infant experienced altered mental status after a fall.
- Initial presentation included respiratory distress consistent with ARDS.
Observation:
- The patient required intubation and mechanical ventilation, including Neurally Adjusted Ventilatory Assist (NAVA).
- Following extubation, poor truncal tone and persistent hypercapnia were observed.
- Multiple extubation attempts failed due to recurrent hypercapnia and bradypnea.
Findings:
- Head CT scans were unchanged, but brain MRI was performed.
- Despite ventilatory support, the patient exhibited significant respiratory compromise.
- The case highlights challenges in managing post-traumatic respiratory and neurological deficits in infants.
Implications:
- This case underscores the importance of comprehensive neurological evaluation after head trauma in children.
- Understanding the interplay between traumatic brain injury and respiratory control is crucial.
- Further investigation may be needed to elucidate the underlying pathophysiology of persistent respiratory failure.
Case Presentation:
An 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.
