LESI LESI Post-Procedure Care and Outcomes 1 — Questions and Answers
Question 1: How long should patients typically be observed in recovery after an LESI before discharge?
- 5-10 minutes
- 15-30 minutes (Correct answer)
- 2-4 hours
- Overnight admission
Correct answer: 15-30 minutes
Patients are typically observed for 15-30 minutes post-ESI to monitor for immediate complications such as vasovagal reactions, allergic responses, or unexpected motor block from local anesthetic.
Question 2: Patients should be instructed to avoid which activity for 24 hours following LESI?
- Taking oral medications
- Driving or operating heavy machinery (Correct answer)
- Drinking water
- Sleeping on their back
Correct answer: Driving or operating heavy machinery
Patients should not drive for 24 hours after ESI because residual local anesthetic effects, sedation from pre-procedural medications, and potential for unexpected neurological effects impair safe driving.
Question 3: Which outcome measure is most commonly used to assess pain relief following LESI in clinical practice?
- Oswestry Disability Index (ODI) only
- Numerical Rating Scale (NRS) or Visual Analog Scale (VAS) for pain intensity (Correct answer)
- EMG/nerve conduction studies
- Serum inflammatory marker (CRP) levels
Correct answer: Numerical Rating Scale (NRS) or Visual Analog Scale (VAS) for pain intensity
The NRS (0-10) and VAS are the standard patient-reported outcome measures for tracking pain intensity before and after ESI in both clinical practice and research settings.
Question 4: What is the appropriate response if a patient calls 48 hours post-ESI reporting worsening back pain and a fever of 101.5°F?
- Prescribe oral antibiotics over the phone and reassure
- Advise ice application and reassure that this is normal steroid flare
- Direct immediately to emergency department for urgent evaluation to exclude epidural abscess (Correct answer)
- Reschedule for a repeat injection in one week
Correct answer: Direct immediately to emergency department for urgent evaluation to exclude epidural abscess
Back pain with fever after ESI must be treated as epidural abscess until proven otherwise; urgent emergency evaluation with MRI is required because delays can result in permanent paralysis.
Question 5: After an ESI, when is the optimal time to assess whether the injection was clinically effective?
- Immediately upon leaving the procedure room
- 2-4 weeks after injection (allowing full steroid effect) (Correct answer)
- 12 months after injection
- Only after three injections in a series
Correct answer: 2-4 weeks after injection (allowing full steroid effect)
The full anti-inflammatory effect of epidural corticosteroids takes 1-2 weeks to develop; re-evaluation at 2-4 weeks provides the best assessment of clinical benefit.
Question 6: A patient reports complete pain relief for 3 weeks after their first LESI but pain gradually returns. What is the recommended next step?
- Proceed directly to surgical consultation
- Consider a repeat injection if clinically appropriate within the recommended annual limit (Correct answer)
- Prescribe long-term opioid therapy
- Discontinue all treatment as the patient failed ESI
Correct answer: Consider a repeat injection if clinically appropriate within the recommended annual limit
If a patient had meaningful but temporary relief (indicating the target was correct), a repeat injection is appropriate and supported by guidelines, typically no sooner than 2-4 weeks after the first.
