Summary

This study tracks how common pain and anesthesia drugs behave in the bodies of children and teens aged 0 to 18. Researchers will measure drug levels in up to 500 participants who are already receiving these medications as part of their standard care. The goal is to create better dosing guidelines tailored to young patients.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Ketorolac, Hydromorphone, Ketamine, Oxycodone, Morphine
What this could lead to
If successful, this could lead to safer, more effective dosing guidelines for pain and anesthesia drugs in children.
What could go wrong
This is an observational study, not a treatment trial. It only measures drug levels, so it won't directly improve care for participants.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Approximately 60 participants will be enrolled to each of the study drug of interests (DOI) cohorts. Participants who satisfy eligibility criteria and are receiving one or more DOIs per standard of care will be consented into the study and assigned to the corresponding DOI cohort. DOI cohort assignments will be at the discretion of the treating physician based on the DOIs that are administered per standard of care. Participants will be selected from a variety of centers including but not limited to trauma and intensive care units. Participants will not be randomized. Participants may count towards 1 or more DOIs within the same 90-day period.
