The analgesic efficacy of ultrasound-guided thoracic paravertebral block in pulmonary tumor ablation surgery: a prospective single-arm study

Background: Local thermal ablation is a rapidly developing minimally invasive treatment for lung tumors. This technique has the advantages of less trauma, ease and convenience of the operation, fast recovery, and fewer complications. Thoracic paravertebral block (TPVB) has been demonstrated can provide sufficient pain relief with high safety. This study aimed to evaluate the efficacy of TPVB for anesthesia management during the ablation surgery of lung tumors.
