Abstract
Nerve blocks in the cervical region may result in some complications due to an unexpected spread of injected local anesthetics. We report a case of transient severe hypertension after a deep cervical plexus block (DCPB) for degenerative cervical spondylosis. A 70-year-old female presented with pain and numbness radiating from the back of the head to the left upper arm. After a series of cervical nerve blocks, an occipital nerve block, a superficial cervical plexus block, and a brachial plexus block were normally provided, and DCPBs were scheduled for the remaining neck pain. Though each DCPB progressed normally with ultrasound guidance, all three consecutive DCPBs led to transient hypertension for more than a half-hour. This is the first report concerning transient hypertension after DCPB. A careful observation of vital signs after cervical nerve block is important to detect some adverse events such as hypertension, caused by the spread of local anesthetics.
