Novel Use of Intranasal Dexmedetomidine for Refractory Irritability in Pediatric Home Care.

Background: Dexmedetomidine is a selective alpha-2 agonist with sedative, analgesic, and anxiolytic properties used intravenously for procedural sedation and in the intensive care unit. The reported use of intranasal (IN) dexmedetomidine for symptom management in pediatric palliative care is limited. Case History: A boy with cardiofaciocutaneous syndrome and refractory irritability was supported by pediatric palliative care throughout numerous hospitalizations for goals of care discussions and pain and symptom management. Given functional and multiorgan system deterioration, he was enrolled in home hospice to optimize comfort measures at anticipated end of life. After the addition of scheduled IN dexmedetomidine for management of irritability, the boy demonstrated marked improvement in comfort and sleep. Conclusion: This case report shows the successful use of IN dexmedetomidine for management of refractory irritability with no noted adverse effects. Future studies and use of this medication will need to consider potential indications, optimal dosing, and long-term effects in the pediatric palliative care setting.
