SPSIP Block vs SAP Block for Post-VATS Pain

Comparison of Superior Serratus Posterior Intercostal Plane Block and Serratus Anterior Plane Block for Pain Management Following Video-Assisted Thoracoscopic Surgery: A Randomized Prospective Study Introduction Video-assisted thoracoscopic surgery (VATS) is associated with lower postoperative pain, shorter hospital stays, and better preservation of pulmonary function compared with conventional thoracotomy, owing to its minimally invasive nature. Although VATS was initially performed using a multi-port technique, it has evolved into a single-port approach, reflecting advances in surgical techniques and equipment. In Uniportal VATS, limiting surgical trauma to a single intercostal space may reduce the risk of chronic postoperative pain by decreasing intercostal nerve damage. Because inadequate pain control after VATS may predispose patients to developing chronic post-thoracotomy pain syndrome (PTPS), effective postoperative analgesia is critically important. Therefore, regional analgesic techniques are recommended as part of multimodal analgesia. PROSPECT guidelines do not recommend the routine use of thoracic epidural analgesia for VATS, despite its effectiveness, because of its invasiveness; instead, they emphasize peripheral blocks such as paravertebral block and erector spinae plane block. Although not included among first-line analgesic interventions in PROSPECT guidelines, the serratus anterior plane block (SAPB) is a widely used and well-established technique in thor…
