Oxycodone Dosing for Elderly Patient with Hip Fracture
For a 71-year-old female (52 kg) with an acute intertrochanteric hip fracture and moderate to severe pain, the recommended initial dose of oxycodone is 2.5-5 mg orally every 4-6 hours as needed, with careful monitoring for respiratory depression and sedation.
Initial Dosing Considerations
Age and Weight Considerations
- For elderly patients (>70 years), oxycodone dosing should be reduced due to:
- Decreased renal function
- Increased sensitivity to opioid effects
- Higher risk of respiratory depression
- Higher risk of delirium 1
Recommended Initial Dosing
- Start with 2.5-5 mg oral oxycodone every 4-6 hours as needed 2
- This is lower than the standard adult starting dose (5-15 mg) recommended in the FDA label
- Titrate based on individual response, balancing pain control with side effects
Multimodal Pain Management Approach
First-Line Treatments (Before Opioids)
Acetaminophen:
- Regular IV acetaminophen every 6 hours 1
- Strongly recommended as first-line treatment
Consider Regional Anesthesia:
- Peripheral nerve blocks are strongly recommended for hip fractures 1
- Reduces preoperative and postoperative opioid requirements
NSAIDs:
- Consider adding if no contraindications 1
- Monitor for renal effects, especially in elderly
Opioid Use Guidelines
- Use oxycodone only for breakthrough pain 1
- Administer for the shortest period at the lowest effective dose
- Immediate-release formulations are preferred over extended-release 1
Monitoring and Titration
Monitoring Parameters
- Respiratory rate and sedation level (most critical)
- Pain scores at rest and with movement
- Mental status (watch for delirium)
- Constipation
Dose Titration
- Reassess efficacy and side effects every 60 minutes after oral administration 3
- If pain remains uncontrolled after 2-3 cycles, consider:
- Increasing dose by 25-50% if no adverse effects
- Changing to alternative pain management strategy
- Consulting pain specialist
Special Considerations for Elderly Patients
Risk Factors to Assess
- Renal function (may require dose reduction)
- Hepatic function (primary site of oxycodone metabolism)
- Concurrent CNS depressants
- History of respiratory conditions
- Cognitive status
Common Pitfalls to Avoid
- Overdosing: Starting with standard adult doses in elderly patients
- Underdosing: Inadequate pain control can delay mobilization and recovery
- Fixed schedules: Using around-the-clock dosing when PRN dosing may be sufficient
- Prolonged use: Most patients with acute fracture pain require opioids for only 3-4 days 4
Practical Recommendations
- Liquid oral formulations may be easier to administer and allow for more precise dosing
- Avoid modified-release opioid preparations in acute settings 1
- Implement non-pharmacological measures (immobilization, ice packs) 1
- Plan for opioid weaning as soon as pain improves
- When pain requirements decrease, wean opioids first, then NSAIDs, then acetaminophen 1
By following these guidelines, you can effectively manage this elderly patient's hip fracture pain while minimizing the risks associated with opioid therapy.
