A number of techniques for thoracic paravertebral block have been described, 18,19,20 but the “classic” TPVB technique with landmarks was comprehensively summarized by Eason and Wyatt based on anatomical landmarks. injection and continuous catheter block, abstract. Performing a thoracic paravertebral block, TPVB consists of injecting a local anesthetic into the thoracic paravertebral space, with the aim of segmental, somatic and sympathetic ipsilateral anesthesia. Ultrasound guidance is becoming the gold standard for the majority of practitioners performing these types of abstract exercises. Paravertebral block, especially thoracic paravertebral block, is an effective regional anesthesia technique that can provide significant analgesia for numerous surgical procedures, including thoracic surgery, pulmonary surgery, and herniorrhagia.
