Description

The aim of this clinical trial is to investigate the effects of local anesthetic diffusion range and sensory block range during retro-SCTLB(retro superior costotransverse ligament space block) and TPVB(thoracic paravertebral block) in patients undergoing CT-guided lung nodule localization. The main issue of the study is to determine the differences in the diffusion range and sensory block range of local anesthetics between the retro-SCTLB and TPVB nerve block methods.

Interventions

  • Ultrasound-guided retro-SCTLB (Procedure)
    Patients undergoing CT-guided lung nodule localization were selected for the study. Before the surgery, the retro-SCTLB was performed under ultrasound guidance.
  • Ultrasound-guided TPVB (Procedure)
    Patients undergoing CT-guided lung nodule localization were selected for the study. Before the surgery, the TPVB was performed under ultrasound guidance.

Eligibility criteria

Inclusion Criteria: Patients scheduled for CT-guided lung nodule localization under local anesthesia will be selected 1. aged 18-80 years 2. BMI 18-30 kg/m² 3. ASA classification I-III Exclusion Criteria: 1. Allergy to the study drug or local anesthetic; 2. History of opioid abuse; 3. Pre-existing skin infection at the puncture site of ITPN or TPVB; 4. Peripheral infectious neuropathy; 5. Dysfunction of blood coagulation
