Insights
A 15 mg dose of intravenous ketorolac provided similar pain relief as higher doses in pediatric emergency department patients. This finding suggests a potentially safer dosing strategy for pediatric pain management with ketorolac.
Area of Science:
- Pediatric Emergency Medicine
- Pharmacology
- Pain Management
Background:
- Ketorolac is frequently used for analgesia in pediatric emergency departments.
- Optimal dosing guidelines for pediatric ketorolac are lacking, increasing the risk of adverse effects.
- Standard pediatric dosing often involves a weight-based approach capped at 30 mg, exceeding typical adult maximums.
Purpose of the Study:
- To compare the analgesic efficacy of a 15 mg dose of intravenous ketorolac against higher doses in pediatric patients.
- To evaluate the impact of ketorolac dosing on pain score reduction in an emergency department setting.
Main Methods:
- A retrospective observational study was conducted at a pediatric tertiary academic medical center.
- Data from July 2021 to July 2022 identified pediatric patients receiving monotherapy intravenous ketorolac (≥15 mg) for acute pain.
- The primary outcome measured was the change in pain score comparing patients who received 15 mg versus >15 mg of ketorolac.
Main Results:
- The study included 599 pediatric patients with comparable baseline demographics between groups.
- No statistically significant difference was observed in pain score reduction between the 15 mg and >15 mg ketorolac dose groups (p=0.84).
Conclusions:
- A capped dose of 15 mg of intravenous ketorolac demonstrated comparable analgesic effects to higher doses in pediatric emergency department patients.
- This suggests that a lower, capped dose may be effective for managing acute pain in this population.
Background:
The use of ketorolac for analgesia in the emergency department is a common practice for pediatric patients. There is a lack of guidance on optimal dosing to limit the risk of side effects especially in pediatric patients. The standard dosing is weight based with a cap at 30 mg, a dose which is higher than the typical max used for adult patients. The objective of this study is to compare the analgesic effect of intravenous ketorolac at doses of 15 mg versus doses greater than 15 mg.
Methods:
This retrospective observational study was performed at a single-center, pediatric tertiary academic medical center. A system-generated report identified patients with an order for IV ketorolac within the ED from July 2021 to July 2022. Pediatric patients presenting to the ED with acute pain and being treated with monotherapy ketorolac for analgesia at a minimum dose of 15 mg were included. The primary outcome of this study evaluated the change in pain score in patients receiving one dose of ketorolac dosed at 15 mg as compared to doses greater than 15 mg.
Results:
Our study population included 599 patients receiving ketorolac IV in the ED with baseline demographics similar between groups. For the primary outcome there was no statistically significant difference in the number of patients with a decrease in pain score between patient groups (p = 0.84).
Conclusion:
This retrospective review demonstrates an association of similar analgesic effects using a capped dose of 15 mg of IV ketorolac as compared to larger doses in pediatric patients admitted to the ED.

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
