Rhomboid Intercostal and Subserratus / Paravertebral Block

Postoperative pain is a significant concern following video-assisted thoracoscopic surgery (VATS). Pain after thoracic surgery not only causes a strong stress reaction and adverse emotional experience but also affects postoperative rehabilitation. Hence, different analgesia techniques, including local anesthetic infiltration, intercostal nerve block, paravertebral block, and thoracic epidural anesthesia, have been described to attenuate the intensity of acute postoperative painparavertebral block (PVB) and Rhomboid intercostal block with sub-serratus plane block (RISS) are the two types of plane blocks used for postoperative analgesia after video-assisted thoracoscopic surgery (VATS). This prospective randomized controlled trial was performed to analyze the postoperative analgesic effects of ultra- sound-guided PVB and RISS block after video-assisted thoracoscopic surgery.
