What is the appropriate acute emergency evaluation, imaging, and management for a 60‑year‑old female with recurrent left‑sided falls, recent left facial swelling, numbness, slurred speech, headache, a history of narcolepsy, failed back‑surgery syndrome, a spinal cord stimulator, and chronic pain treated with high‑dose Percocet (oxycodone/acetaminophen), naproxen, methocarbamol, sumatriptan, and topiramate?

Immediate Emergency Evaluation and Management

This patient requires urgent emergency department evaluation with brain and cervical spine imaging to rule out stroke, intracranial hemorrhage, and cervical spine injury—the recurrent left-sided falls, facial numbness, slurred speech, and progressive left-sided weakness pattern constitute neurological red flags that demand immediate workup regardless of negative facial X-rays. 1, 2

Critical Red Flags Present

This patient exhibits multiple concerning features that mandate emergent evaluation:

• Recurrent unilateral (left-sided) falls with progressive pattern over time 1
• Acute neurological deficits: facial numbness, slurred speech (now improved but was present), left-sided facial swelling/ecchymosis 2, 3
• New-onset headache at base of skull, distinct from her usual migraine pattern and unresponsive to sumatriptan 3, 4
• Progressive left-sided weakness with frequent object dropping bilaterally 1
• Age 60 years with high-energy mechanism (significant facial impact) 1, 2

The combination of unilateral falls, facial trauma, transient speech disturbance, and atypical headache raises immediate concern for posterior circulation stroke, vertebral artery dissection, subdural hematoma, or cervical spine injury with cord compression 1, 3, 5.

Immediate Imaging Protocol

Brain Imaging - First Priority

Obtain non-contrast CT head immediately to exclude acute intracranial hemorrhage (subdural, epidural, or intraparenchymal hematoma) and mass effect 1, 2, 4. The ACR Appropriateness Criteria designate CT as the initial study for acute facial trauma with neurological symptoms 2.

Follow with brain MRI without contrast if CT is negative but neurological symptoms persist, as MRI is superior for detecting:

• Acute ischemic stroke (particularly posterior circulation) 1
• Brainstem or cerebellar pathology 1
• Subtle traumatic brain injury 1
• Spinal cord pathology at the craniocervical junction 1

Cervical Spine Imaging - Concurrent Priority

Obtain CT cervical spine immediately given the mechanism (multiple falls with head/facial impact) and new occipital headache 1. CT cervical spine has 94-100% sensitivity for fractures and is the standard for trauma clearance 1.

Add MRI cervical spine without contrast if:

• CT shows fracture or malalignment 1
• Neurological deficits are present (which they are in this case) 1
• Patient reports new neck pain or occipital headache (present here) 1

MRI is essential to evaluate for ligamentous injury, spinal cord compression, epidural hematoma, or vertebral artery dissection that may not be visible on CT 1. The guideline specifically states MRI is "the crucial diagnostic tool in the assessment of patients with suspected spinal cord injury" 1.

Additional Imaging Considerations

CT angiography of head and neck should be strongly considered given the constellation of symptoms suggesting possible vertebral or carotid artery dissection (recurrent falls, facial trauma, atypical headache, neurological deficits) 4.

Emergency Department Management

Immediate Actions

• Maintain cervical spine precautions until imaging excludes injury 1
• Obtain vital signs including blood pressure (both NSAIDs and opioids can affect BP) 6
• Perform detailed neurological examination documenting:
  • Cranial nerve function (especially facial sensation, motor function) 2
  • Motor strength in all extremities (quantify left-sided weakness) 1
  • Sensory examination (document facial and extremity numbness) 2
  • Cerebellar testing (given recurrent falls) 3
  • Gait assessment if safe 3

Laboratory Evaluation

• Complete blood count to assess for thrombocytopenia (patient on chronic naproxen) 6
• Comprehensive metabolic panel including renal function (BUN, creatinine) given chronic NSAID use and age >60 6
• Liver function tests (patient on chronic acetaminophen via Percocet 4-5 times daily) 6
• Coagulation studies if intracranial hemorrhage is suspected 4

Critical Medication Safety Issues

High-Risk Opioid Regimen

This patient is taking Percocet (oxycodone/acetaminophen) 4-5 times daily, which represents a significant opioid burden with multiple safety concerns:

Sedation and fall risk: The FDA label explicitly warns that opioids cause "severe drowsiness, decreased awareness" and impair coordination 7. Opioid-induced sedation is a likely contributor to her recurrent falls 7.

Respiratory depression risk: At age 60, she is approaching the geriatric threshold where "elderly patients may have increased sensitivity" and face "respiratory depression as the chief risk" 7. The combination of high-dose opioids with her narcolepsy (which already causes excessive daytime sleepiness) creates compounded sedation risk 8, 9.

Polypharmacy interactions: The FDA label warns that "taking PERCOCET with other opioid medicines, benzodiazepines, alcohol, or other central nervous system depressants can cause severe drowsiness, decreased awareness, breathing problems, coma, and death" 7. Her methocarbamol (muscle relaxant) adds to CNS depression 7.

NSAID Toxicity Risk

This patient meets multiple high-risk criteria for NSAID complications on chronic naproxen 500 mg:

• Age 60 years (guideline threshold for increased GI, renal, and cardiac toxicity) 6
• Chronic high-dose use (naproxen 500 mg chronically) 6
• Concomitant opioid use (Percocet 4-5 times daily) increases bleeding risk 6
• No documented monitoring (guidelines require baseline and q3-month CBC, renal function, liver function, BP, fecal occult blood) 6

Immediate NSAID discontinuation should be considered given acute head trauma with facial swelling and the need for potential neurosurgical intervention 6. NSAIDs increase bleeding risk and should be stopped if surgical intervention is anticipated 6.

Narcolepsy and Fall Risk

Her narcolepsy is a critical factor in recurrent falls. The first fall occurred "during narcoleptic episode" in the shower 8. However, opioids may paradoxically worsen narcolepsy symptoms despite some evidence suggesting benefit 9. The current high-dose opioid regimen is more likely contributing to falls through sedation than helping her narcolepsy 7, 8.

Disposition and Follow-Up

If Imaging Reveals Acute Pathology

• Neurosurgical consultation for any intracranial hemorrhage, mass effect, or unstable spine fracture 1
• Stroke neurology consultation for acute ischemic stroke 4
• Hospital admission for observation and further management 1, 4

If Imaging is Negative

Do not discharge without neurology consultation given the progressive nature of symptoms and high pretest probability of neurological disease. The pattern of recurrent left-sided falls with progressive weakness suggests an evolving process that may not yet be visible on imaging 1, 3.

Outpatient neurology referral within 24-48 hours is inadequate—this patient needs same-day evaluation 3, 4.

Pain Management Restructuring

Immediate Changes

Reduce or eliminate Percocet given fall risk and lack of efficacy (she reports inadequate pain control despite 4-5 doses daily) 7. The FDA label states "if your pain gets worse after you take PERCOCET, do not take more" and to contact the provider 7.

Consider duloxetine 30 mg daily for one week, then 60 mg daily for neuropathic pain component (left arm pulling sensation, nerve-related pain from failed back syndrome) 10. Duloxetine has analgesic efficacy independent of antidepressant effects and does not carry fall risk like opioids 10.

Discontinue naproxen given age >60, chronic use without monitoring, acute head trauma, and lack of documented efficacy 6. If NSAID is needed after acute period, consider selective COX-2 inhibitor with gastroprotection and close monitoring 6.

Contraindications to Current Regimen

Topiramate 300 mg may contribute to cognitive slowing and coordination problems, potentially worsening fall risk 11. However, do not abruptly discontinue due to seizure risk 11.

Methocarbamol 1400 mg adds to CNS depression with opioids and should be tapered or discontinued 7.

Common Pitfalls to Avoid

• Do not attribute all symptoms to chronic pain syndrome or narcolepsy—new neurological deficits require full workup 3, 4
• Do not rely on negative facial X-rays—they do not exclude intracranial or cervical spine pathology 1, 2
• Do not continue cervical collar beyond 48 hours without clear indication—prolonged immobilization worsens outcomes 1
• Do not discharge with "follow up with PCP"—this requires emergency or urgent specialty evaluation 3, 4
• Do not increase opioid dose for worsening pain—this suggests treatment failure and need for alternative approach 7
