Abstract: | Thoracic paravertebral block is the technique of injecting local anesthetic adjacent to the intervertebral foramina, resulting in unilateral somatic and sympathetic nerve blockade. Previous studies have reported its effectiveness for thoracic surgery including breast surgery and relief of postoperative and chronic pain of unilateral origin from the chest and abdomen. The technique is relatively easy to learn and safer than thoracic epidural. Its clinical advantages include the inhibition of stress and pressor responses to surgical stimuli, maintenance of hemodynamic stability, low incidence of complication, long duration of analgesia, and few contraindications. Recent advances in ultrasound technology can further increase the effectiveness and the safety of thoracic paravertebral block, although identification of the nerve and needle is not still possible. |
