‘Still an Unknown’
Seniha Nur Ozudogru, MD, assistant professor of clinical neurology at Penn Medicine in Philadelphia, echoed the need for further study.
The role of IV ketamine in refractory pediatric headache is “still an unknown,” said Dr. Ozudogru, who was not involved in the study.
She noted that currently, there is “no standard protocol for ketamine infusion, even for adults. Every institution has their own protocols, which makes it difficult.”
Dr. Ozudogru also wonders how “doable” in-hospital IV infusions over 3 days may be for children.
“Especially for chronic migraine patients, it can be really tricky to manage expectations in that even if they don’t respond and the headache doesn’t go away, they still may have to be discharged. That requires a specific approach and discussion with the patients,” Dr. Ozudogru said.
Intranasal ketamine is another potential option, she said, with a recent study suggesting that intranasal ketamine is an effective treatment for children hospitalized with refractory migraine.
“However, there is some concern about the potential of addiction and the side effects of hallucinations and what the main protocol will be, so this not a standard treatment and has to be studied further,” she said.
The study had no specific funding. Dr. Rosenthal and Dr. Ozudogru have no relevant disclosures.
