See the 60-second demo →Regional anesthesia (epidural, spinal, peripheral nerve block) is performed millions of times per year in the US with low complication rates — but when neurologic complications occur, they tend to be catastrophic. Permanent paraplegia, foot drop, brachial plexus injury. The American Society of Regional Anesthesia (ASRA) has well-established guidelines for safe regional anesthesia. When those guidelines are violated, plaintiff verdicts follow.
The High-Risk Complications
Spinal/epidural hematoma
Bleeding into the spinal canal after regional anesthesia. Compresses spinal cord. Permanent paralysis if not surgically decompressed within 8-12 hours.
Risk factors: anticoagulants (warfarin, DOAC, LMWH, heparin), antiplatelets (aspirin, clopidogrel, ticagrelor), thrombocytopenia, coagulopathy. ASRA guidelines specify exact timing windows for safe neuraxial procedures relative to each anticoagulant. Violation of these windows is documented breach.
Standard of care: any patient on anticoagulants requires verification of timing before neuraxial procedure. Post-procedure, neurological checks every 2-4 hours. Any new lower-extremity weakness, back pain, or sensory deficit requires immediate MRI + neurosurgery consultation. Decompression within 8 hours is the standard.
Direct nerve injury
Needle trauma to spinal nerve roots or peripheral nerves. Risk factors: paresthesia during placement, multiple needle passes, deep needle insertion without ultrasound guidance.
Standard of care: severe paresthesia during placement is a stop sign. Withdraw, reposition, do not inject through pain. ASRA recommends ultrasound guidance for peripheral nerve blocks. Pre-procedure documentation of motor and sensory baseline.
Anterior spinal artery syndrome
Compression or injection-related compromise of the anterior spinal artery. Causes paralysis below the level of injury. Rare but catastrophic.
Cauda equina syndrome from regional
Direct trauma or chemical injury to the cauda equina nerve roots. Bowel/bladder dysfunction, saddle anesthesia, lower-extremity weakness.
Total spinal anesthesia
Accidental high spinal — anesthetic ascending too high, causing hypotension, bradycardia, respiratory arrest. Often from inadvertent intrathecal injection during attempted epidural.

Try Timeline Builder →The Common Breach Patterns
1. ASRA timing window violated
Patient on apixaban; ASRA requires 72 hours between last dose and neuraxial procedure. Patient gets epidural at 48 hours. Develops spinal hematoma.
2. Paresthesia ignored
Patient reports severe paresthesia during block placement. Provider continues, injects anyway. Permanent nerve damage results.
3. Post-procedure neuro checks not performed
Patient develops new lower-extremity weakness 6 hours after epidural. Nursing doesn't check, doesn't escalate. Diagnosis of spinal hematoma delayed beyond 8-hour decompression window.
4. MRI delayed
Neurological deficit recognized but MRI not obtained immediately. Or MRI obtained but neurosurgical consultation delayed.
5. Ultrasound not used for high-risk patients
Peripheral nerve block performed by landmark technique only in a patient with difficult anatomy (obesity, prior surgery). Multiple needle passes. Nerve injury.

- Post-procedure neurological assessment frequency and findings
- Imaging studies and timing
- Neurosurgical consult timing if obtained

Damages
- Permanent paraplegia from spinal hematoma: $5M-$15M typical
- Foot drop, partial peripheral nerve injury: $500K-$2M
- Cauda equina with bowel/bladder dysfunction: $3M-$8M
- Total spinal with respiratory arrest and hypoxic brain injury: $5M-$15M
Bottom Line
Regional anesthesia injuries are well-defined in the medical literature with clear standard-of-care frameworks (ASRA). The breaches are documented in the anesthesia record and the post-procedure neuro checks. Causation in spinal hematoma cases follows the 8-hour decompression window. These are technically complex cases but the standards are clear, and damages are substantial.
