The aim of this clinical trial is to investigate the effects of postoperative analgesia during retro-SCTLB(retro superior costotransverse ligament space block) and TPVB(thoracic paravertebral block) in patients undergoing thoracoscopic radical resection of lung cancer。By comparing the dosage of opioid drugs after surgery, the impact of retro-SCTLB and TPVB on the postoperative analgesic effect was evaluated.
Patients scheduled for thoracoscopic radical lung cancer surgery under general anesthesia；
aged 18-80 years；
BMI 18-30 kg/m²；
ASA classification I-III；
Allergy to the study drug or local anesthetic;
History of opioid abuse;
Pre-existing skin infection at the puncture site of ITPN or TPVB;
Peripheral infectious neuropathy;
Parallel
Ultrasound-guided retro-SCTLB
Procedure/SurgeryPatients undergoing thoracoscopic radical resection of lung cancer were selected for the study. Before the surgery, the retro-SCTLB was performed under ultrasound guidance。
Ultrasound-guided TPVB
Procedure/SurgeryPatients undergoing thoracoscopic radical resection of lung cancer were selected for the study. Before the surgery, the TPVB was performed under ultrasound guidance.
Postoperative sufentanil dosage
Cumulative sufentanil dosage 24 hour postoperatively
NRS(Numeric Rating Scales) score
Postoperative 1, 3, 6, 12, 24 and 48 hour NRS (Numeric Rating Scales) score during the resting and active . Numerical Rating Scale (NRS): This scale is composed of 11 numbers from 0 to 10, with higher numbers increasing the severity of pain.
Opioid dosage
opioid consumption dosage during the operation
Adverse reaction
This includes dizziness, nausea, vomiting, etc
Time of first ambulation after surgery
The early time of the first postoperative ambulation indicates that the nerves blocks has a good effect.
