Can Ultrasound-Guided Continuous Paravertebral Block Reduce the Incidence of Chronic Postsurgical Pain in Patients with Thoracoscopic Lung Cancer Surgery? A Randomized Controlled Trial

<div>The nerve block needle reached the position through the out-of-plane technique (A); after confirming negative aspiration, ropivacaine was injected (B). TP, transverse process; PP, parietal pleural; SCTL, superior costotransverse ligament; TPVS, thoracic paravertebral space; probe selection: low-frequency linear array probe; yellow arrow: puncture approach.</div>
