Ketorolac Use in 10-Year-Old Children
Ketorolac is appropriate and effective for acute pain management in 10-year-old children, administered intravenously at 0.5 mg/kg (not to exceed 30 mg as a single dose), with oral continuation therapy contraindicated in this age group per FDA labeling. 1
FDA-Approved Dosing and Route
- The FDA explicitly states that oral ketorolac is NOT approved for children under 17 years of age. 1
- Intravenous ketorolac is the appropriate route for a 10-year-old child at 0.5 mg/kg per dose. 2
- The recommended IV dosing regimen is 0.5 mg/kg as an initial dose, followed by either bolus injections of 1.0 mg/kg every 6 hours OR a continuous infusion of 0.17 mg/kg/hour. 2
- Maximum daily dose should not exceed 90 mg, and treatment duration must be limited to 48 hours maximum in pediatric patients. 2
- Intramuscular injections should be avoided in children unless IV access is unavailable. 2
Clinical Efficacy in Pediatric Populations
- Ketorolac provides analgesic efficacy equivalent to morphine and superior to codeine for postoperative pain in children. 2
- Recent meta-analysis demonstrates a mean pain score reduction of -2.06 points with ketorolac in pediatric patients. 3
- Pain freedom at discharge was achieved in 66% of pediatric patients treated with ketorolac. 3
- Ketorolac reduces postoperative opioid requirements by 25-50% when used as part of multimodal analgesia. 4, 5
Critical Safety Considerations and Contraindications
Absolute contraindications in children include: 6
- Active or history of gastrointestinal bleeding or peptic ulcer disease
- Known hypersensitivity to aspirin or other NSAIDs
- Renal impairment or compromised kidney function
- Compromised hemostasis or bleeding disorders
Special caution is required in: 4, 7
- Children with sickle cell disease (particularly during vaso-occlusive crisis) due to elevated acute kidney injury risk 4, 7
- Children with mastocytosis (one lethal idiosyncratic reaction reported in an adult; recommend complete avoidance) 4
- Patients with marginal baseline kidney function 7
- Dehydrated or volume-depleted children 7
Monitoring Requirements
Before initiating ketorolac therapy, obtain: 8
- Baseline blood pressure
- BUN and creatinine
- Complete blood count
- Liver function tests
During therapy, monitor for: 6, 3
- Signs of gastrointestinal bleeding (the pooled rate of GI adverse events is only 1.53% in pediatric patients) 3
- Renal function deterioration
- Bleeding complications (bleeding time may be slightly increased but typically remains within normal limits) 2
Clinical Advantages Over Opioids
- Ketorolac provides opioid-level analgesia without respiratory depression, sedation, nausea/vomiting, urinary retention, or addiction potential. 5, 2
- Unlike opioids, ketorolac can be discontinued abruptly without withdrawal symptoms. 5
- Recovery of bowel function after abdominal surgery occurs sooner with ketorolac compared to opioid-treated patients. 2
- When combined with opioids, ketorolac exhibits marked opioid-sparing effects, reducing opioid-related adverse events. 2
Pharmacokinetic Considerations in Children
- Children have a 2-fold increased volume of distribution compared to adults, requiring higher weight-based dosing. 2
- Plasma clearance is higher in children due to lower plasma protein binding. 2
- Despite these differences, elimination half-life remains similar to adults, so dosing intervals remain the same (every 6 hours). 2
- Younger children and infants may require slightly higher dosages than older children to achieve equivalent pain relief. 2
Common Pitfalls to Avoid
- Do not prescribe oral ketorolac for discharge in a 10-year-old—this is off-label and not FDA-approved for children under 17 years. 1
- Do not exceed 48 hours of IV therapy in pediatric patients (unlike the 5-day limit in adults). 2
- Do not use ketorolac in children with even marginal renal impairment without careful risk-benefit assessment. 7
- Do not administer intramuscular injections as first-line in children when IV access is available. 2
- Avoid ketorolac entirely in children with mastocytosis due to reported fatal reactions. 4
