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.

This is a prospective, randomized controlled study. Patients who are scheduled for elective uniportal thoracoscopic surgery in our hospital will be enrolled. Patients will be randomly assigned to one of the three groups: ultrasound-guided paravertebral block, ultrasound-guided erector spinae block, or intravenous patient-controlled analgesia pump group. Different nerve block operation schemes will be used in different groups. In any of the three groups, general anesthesia will be performed according to the standard, and multi-mode analgesic treatment will be appied as the combination of NSAIDs analgesics, opioid analgesics, and postoperative rescue analgesic treatment. Participants will be followed up at 1, 4, 12, 18 hours, on 1, 2, 3, 4, 7 days, and in 1, 2, 3, 4, 6 months after surgery. At each follow-up visit, rest and cough pain level will be recorded, and sense of touch and pain in the chest will be examined. Additional analgesic treatment will be given if necessary. Comparisons of the postoperative analgesic use, cough and rest pain, ambulation time, length of hospital stay, and hospital costs will be made in the three groups.

Patients in this group will receive ultrasound-guided paraspinal block with 0.3% ropivacaine and 5mg dexamethasone in total of 20mL saline at T5 level on the operative side. Patients in all the groups will be treated with PCIA after surgery. PCIA with sufentanil will be applied to all participants, with background infusion at 1.8μg/hour, and total dosage \<5μg/hour.

RECRUITINGtotal opioid consumption
total opioid (morphine equivalent/body weight) consumption from the end of the surgery to the time of discharge.
Time frame: up to 6 months, total opioid use from postoperative period till the discontinuation of surgery-related therapy.
postoperative pain score assessed by Visual Analogue Scale VAS (1-10)
rest and cough pain
Time frame: from the time at the end of surgery to 24 weeks after surgery
postoperative pain score assessed by Numeric Rating Scales, NRS (1-10)
rest and cough pain
Time frame: from the time at the end of surgery to 24 weeks after surgery
sensations of touch on the chest wall
difference in tactile sense on bilateral chest-wall. Tactile sensation and cold sensation will be measured at four points (\<3cm near the incision, and on the other side on the symmetrical chest wall, and at the point of bilateral mid-clavicular-costal arch) with an alcohol-stained cotton swab
Time frame: from the time at the end of surgery to 24 weeks after surgery
non-opioid analgesic drug use
number of patients with long-term (≥3 days) use of non-opioid analgesic drug
Time frame: from the time at the end of surgery to 24 weeks after surgery
length of stay (LOS)
days of hospital stay
Time frame: up to 1 month, LOS is the amount of days the patient spends in the hospital, determined by subtracting the date of admission from the date of discharge
ambulation time
first time of successful activity off bed, the time between the end of surgery to the time of the first successful ambulation
Time frame: up to 1 month, ambulation time is the time the patient first ambulated following the surgical procedure
total cost of hospitalization
the in-patients costs total cost of hospitalization=medication cost + hospitalization cost + nursing cost + delay compensation
Time frame: up to 1 month, total charges settled on the day of discharge
long-term postoperative analgesia
number of patient who needs long-term postoperative analgesia (≥3 days after discharge)
Time frame: from the time at the end of surgery to 24 weeks after surgery
