The Impact of Different Regional Anesthesia Techniques on the Incidence of Chronic Post-surgical Pain in Patients Undergoing Video-Assisted Thoracoscopic Surgery: A Network Meta-analysis

Chronic post-surgical pain (CPSP) remains a prevalent issue following video-assisted thoracic surgery (VATS), despite advancements in surgical techniques. Various regional anesthesia techniques, including thoracic paravertebral block (PVB), intercostal nerve block (ICNB), serratus anterior plane block (SAPB), erector spinae plane block (ESPB), and thoracic epidural anesthesia (TEA), have been employed in VATS procedures to mitigate this issue. This study aims to compare the efficacy of these analgesia methods in reducing the incidence of CPSP in VATS patients through a network meta-analysis.
