Local Anaesthetic Spread and Sensory Block Range of the Retro-superior Costotransverse Ligament Space Block

Comparison of Local Anaesthetic Spread Between the Retro-superior Costotransverse Ligament Space Block and Thoracic Paravertebral Block: A Three-dimensional CT Reconstruction Imaging Study

Sponsor

Nanjing First Hospital, Nanjing Medical University

Enrollment

50 participants

Start Date

Sep 12, 2025

Study Type

INTERVENTIONAL

Conditions

Nerve BlockPulmonary Nodules

Summary

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.

Plain Language Summary

Simplified for easier understanding

This study is comparing how well a new type of nerve block (called the Retro-Superior Costotransverse Ligament Space Block) spreads local anesthetic and numbs sensation, in patients having a CT-guided procedure to mark small lung nodules before surgery. **You may be eligible if...** - You are between 18 and 80 years old - You are scheduled for a CT-guided lung nodule localization procedure under local anesthesia - Your BMI is between 18 and 30 - Your health status is classified as ASA I–III (relatively stable health) **You may NOT be eligible if...** - You are allergic to the study drug or any local anesthetic - You have a history of opioid abuse - You have a skin infection at the injection site - You have nerve damage in the area to be treated - You have a blood clotting disorder Talk to your doctor to see if this trial is right for you.

Interventions

PROCEDUREUltrasound-guided retro-SCTLB

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

PROCEDUREUltrasound-guided TPVB

Patients undergoing CT-guided lung nodule localization were selected for the study. Before the surgery, the TPVB was performed under ultrasound guidance.
