Optimization of Perioperative Analgesia Protocol for Uniportal Video-assisted Thoracoscopic Surgery: a Randomized Controlled Trial
Trial design Despite video-assisted thoracic technology and procedure specific postoperative pain management (PROSPECT) have been promoted through recent years, thoracic surgery is still considered to be one of the most painful of surgical procedures. This study aims to optimize these conditions according to different perioperative analgesic modes recommended at present. This will be a single-blind randomized study to investigate the optimal analgesic effect of thoracic paravertebral block (TPB), erector spinae block (ESB), or sufentanil patient controlled intravenous analgesia (PCIA) for uniportal video-assisted thoracoscopic surgery (uVATS) and using minimally invasive drainage. Methods One-hundred and two patients undergoing uVATS will be enrolled. Patients will be randomly assigned to PVB group (20mL 0.3% ropivacaine with dexamethasone), ESB group (20mL 0.3% ropivacaine with dexamethasone) or CON group. PCIA with sufentanil will be provided to all patients after surgery. Primary outcome will be total opioid consumption from the end of the surgery to the time of discharge. Secondary outcomes consist of postoperative pain score, postoperative chronic pain, both at rest and during coughing, sensations of touch and pain on the chest wall, non-opioid analgesic drug use, length of stay (LOS), ambulation time, total cost of hospitalization and long-term postoperative analgesia. Adverse reaction to analgesics and adverse event related to regional block will also be recorded. Ethics and dissenmination This study is approved by the Ethics Committee of China-Japan Friendship Hospital (ID 2022-KY-127-1). The results will be published in peer-reviewed journals.
