Analgesia for Fracture Reduction in Geriatric Patients

First-Line Approach

The American College of Emergency Physicians recommends regular administration of intravenous acetaminophen every 6 hours as the cornerstone of pain management for geriatric patients undergoing fracture reduction 1
Oral acetaminophen can be substituted if IV access is limited, as studies show equivalent efficacy for pain control in elderly trauma patients 2
Consider adding NSAIDs for severe pain, but carefully evaluate potential adverse effects and drug interactions in the elderly population 1

Peripheral nerve blocks should be placed at the time of presentation to reduce both preoperative and postoperative opioid requirements 1
For upper extremity fractures: brachial plexus blocks are recommended 1
Thoracic epidural and paravertebral blocks are strongly recommended for patients with rib fractures, as they improve respiratory function and reduce opioid consumption, infections, and delirium 1, 2
Carefully evaluate the use of neuraxial and plexus blocks in patients receiving anticoagulants to avoid bleeding complications 1

Low-dose ketamine (0.3 mg/kg IV over 15 minutes) can be considered as an alternative to opioids, providing comparable analgesic efficacy with fewer cardiovascular side effects 2
Gabapentinoids may be included as part of the multimodal approach, particularly for neuropathic pain components 1
Lidocaine patches applied to the area of pain can provide localized analgesia without systemic effects 1

Reserve opioids only for breakthrough pain, administered for the shortest period possible at the lowest effective dose 1, 3
When opioids are necessary, implement progressive dose reduction due to the high risk of accumulation, over-sedation, respiratory depression, and delirium in elderly patients 3

Implement non-pharmacological measures such as proper positioning, immobilization techniques, and application of ice packs to the affected area 1, 4
These should be used in conjunction with pharmacological therapy to enhance pain control 1

Systematic pain evaluation is crucial as elderly patients often receive inadequate analgesia despite reporting moderate to high pain levels 3
Elderly patients with cognitive impairment often receive inadequate pain management, leading to poorer mobility, quality of life, and higher mortality 3

Avoid excessive reliance on opioids, as both inadequate analgesia and excessive opioid use increase the risk of postoperative delirium in elderly patients 3
Regular reassessment of pain and analgesic efficacy is essential to optimize pain control while minimizing adverse effects 4

The World Journal of Emergency Surgery recommends that NSAIDs are contraindicated in patients with moderate renal impairment (GFR <45) and concurrent aspirin use due to increased risks of bleeding, gastrointestinal complications, acute kidney injury, and cardiovascular events 5
Elderly patients are particularly vulnerable to morphine accumulation leading to over-sedation, respiratory depression, and delirium, according to the World Journal of Emergency Surgery 5
Tramadol may be considered as it has reduced respiratory and gastrointestinal depression compared to other opioids, but confusion may be problematic and it is contraindicated in patients with seizure history, as stated in the World Journal of Emergency Surgery 5
Avoid concomitant use with other CNS depressants (benzodiazepines, skeletal muscle relaxants) outside highly monitored settings, as recommended by the World Journal of Emergency Surgery 5

Early mobilization as tolerated to prevent complications is recommended, according to the Annals of the Rheumatic Diseases 6

The World Journal of Emergency Surgery advises against delaying pain medication administration, as drugs should be administered early in trauma patients 5
The World Journal of Emergency Surgery also recommends not relying solely on patient self-report, but instead using behavioral pain assessment tools (CPOT, BPS) for non-verbal patients 5
