There are clear clinical and logistic reasons for pursuing the best possible post-operative pain management avoiding the negative side effects of opioid treatment; in order to garantee an enhanced recovery after surgery. A short hospital stay is fundamental to reduce patient morbidity and costs. Regional anesthetic nerve blocks are an ideal option to achieve this goal.~Paravertebral block serves as an ideal approach for thoracic and abdominal surgery through delivering segmental anesthesia of operative sites. Thoracic paravertebral block has superior analgesia as well as fewer complications than systemic opioids. It has been successfully applied in sternotomy, breast surgery, abdominoplasty, and laparoscopic cholecystectomy. ESP block is a recently described technique, with promising results in different scenarios. It probabily has a better risk profile than PVB, for its lower possibility of accidental pleural puncture and reabsorption of local anesthtetic than PVB one
The aim of the study is to compare two different locoregional techniques in VATS.
