Successful Mx of High Spinal Anesthesia Following C2-C3 Face
Occipital nerve blocks into the C2-C3 facet joint have proven to be a safe and effective form of treatment for occipital neuralgia.The third occipital nerve crosses the C2-C3 joint opposite the C3 superior articular process at its center.
Direct complications from cervical facet joint blocks are rare, and include intravascular injection, infection and, more rarely, intrathecal injection.

Intrathecal injection can lead to high spinal anesthesia, a medical emergency that can result in bradycardia, asystole and/or cardiopulmonary arrest.

Early recognition and intervention are crucial to reducing morbidity and mortality. the use of high spinal anesthesia and subsequent cardiopulmonary arrest reported in a patient receiving a fluoroscopy-guided bilateral C2-C3 occipital nerve block. The patient was managed with cardiopulmonary resuscitation (CPR), intubation and vasopressor support....
