Thoracic paravertebral block technique

Paravertebral blocks are typically done using ultrasound guidance to precisely localize the injection and improve success, and to avoid the pain of needle contact with bone (not shown). An anatomic landmark approach is an alternative technique, as shown here, with placement of a paravertebral block between the T4 and T5 transverse processes. For further details, please refer to UpToDate topics addressing nerve blocks of the trunk, including the thoracic paravertebral block.
