In this episode of "PICU Doc on Call," Drs. Monica Gray, Pradip Kamat, and Rahul Damania discuss the use of intranasal medications in pediatric intensive care. Using the case of a four-month-old infant needing an MRI, they explore when and why intranasal drugs are preferred over IV access, the science behind nasal drug delivery, safe administration techniques, and common medications used. The episode highlights the benefits of intranasal sedation—such as rapid onset and needle-free delivery—while emphasizing teamwork and careful monitoring for safe, effective pediatric care.

Show Highlights:

• Use of intranasal medications in pediatric intensive care settings
