Comparison of Local Anaesthetic Spread Between the Retro-superior Costotransverse Ligament Space Block and Thoracic Paravertebral Block: A Three-dimensional CT Reconstruction Imaging Study
Status: Recruiting
Location: See all (2) locations...
Intervention Type: Procedure
Study Type: Interventional
Study Phase: Not Applicable
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.

Target number of participants: 50
Treatments
Experimental: retro-SCTLB group
A total of 20 ml of the local anesthetic solution (0.375% ropivacaine 10ml+ iohexol 10ml) is injected in the retro-superior costotransverse ligament space in the retro-SCTLB group within 60 seconds.
Experimental: TPVB group
A total of 20 ml of the local anesthetic solution (0.375% ropivacaine 10ml+ iohexol 10ml) is injected in the paravertebral space in the TPVB group within 60 seconds.
