Nerve block comparison for CT-guided lung nodule localization: retro‑SCTLB versus TPVB

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Forty adults undergoing CT-guided lung nodule localization under local anesthesia will be randomized 1:1 to receive either ultrasound-guided retro‑SCTLB or ultrasound-guided TPVB before the localization procedure. Group allocation is concealed using sealed opaque envelopes prepared by an uninvolved nurse to maintain objectivity. The study will compare the radiographic diffusion range of the local anesthetic and the sensory block range measured after the block. Standard inclusion criteria include age 18–80, BMI 18–30 kg/m², and ASA I–III, while patients with local infection, coagulation dysfunction, opioid abuse history, or allergy to local anesthetics are excluded.
