Summary
A rare case of acute neurogenic pulmonary edema occurred after bupivacaine hydrochloride trigeminal nerve blockade. Neurologic deficits suggest brain stem involvement in this previously unreported complication.
Area of Science:
- Neurology
- Anesthesiology
- Pulmonary Medicine
Background:
- Trigeminal nerve blockade is a common procedure for facial pain.
- Bupivacaine hydrochloride is a frequently used anesthetic agent.
Observation:
- A 32-year-old man developed acute neurogenic pulmonary edema immediately following bupivacaine hydrochloride injection into the trigeminal cistern.
- The patient had atypical facial pain and no prior cardiopulmonary issues.
Findings:
- This represents a previously unreported complication of trigeminal nerve blockade.
- Associated neurologic deficits were observed, indicating potential brain stem involvement.
Implications:
- The findings suggest the brain stem plays a crucial role in the development of neurogenic pulmonary edema after trigeminal nerve blockade.
- This case highlights the importance of monitoring for pulmonary complications after such procedures.
