Pain Management for Elderly Patients with Rheumatoid Arthritis and Head Injury

First-Line Treatment

• For an elderly patient with rheumatoid arthritis and a head injury who is allergic to paracetamol, intravenous ketorolac is recommended as the first-line analgesic option, with careful consideration of reduced dosing in elderly patients 1, 2

Important Considerations

• The patient's age requires dose reduction of all analgesics due to altered pharmacokinetics and increased sensitivity to adverse effects 1, 2
• History of rheumatoid arthritis suggests chronic NSAID use, which may affect the efficacy and safety profile of additional NSAIDs 3
• Head injury requires careful monitoring for neurological status, making opioid-sparing strategies preferable 1, 4

Multimodal Approach

• Consider regional anesthesia techniques if appropriate for the location of injury and if expertise is available 1, 2
• Non-pharmacological measures such as proper positioning, ice application, and immobilization should be implemented concurrently 1, 2

Monitoring and Precautions

• Monitor vital signs closely, particularly blood pressure, as NSAIDs and opioids can cause hypotension in elderly patients 1
• Assess renal function before administering ketorolac, as elderly patients are at higher risk for NSAID-induced nephrotoxicity 1

Contraindications to Consider

• Avoid ketorolac if the patient has renal impairment, history of GI bleeding, or concurrent anticoagulant use 5
• Use caution with morphine if there are signs of increased intracranial pressure from the head injury 4
• Consider drug interactions with the patient's RA medications when selecting analgesics 1, 3
