Performing regional nerve blocks in anesthetized adults is debated. This case study supports an individualized approach, using ultrasound-guided blocks in complex patients, even when heavily sedated, to manage hypertrophic obstructive cardiomyopathy.
Area of Science:
- Anesthesiology
- Cardiology
- Regional Anesthesia
Background:
- The safety of performing regional anesthesia in heavily sedated or anesthetized adults is controversial.
- Potential benefits include early detection of nerve injury or local anesthetic systemic toxicity in conversant patients.
- Limited data exists on performing these blocks in non-conversant, heavily sedated patients.
