Impact of Different Injection Rate on Local Anaesthetic Spread of Ultrasound-guided Erector Spinae Plane Block
Status: Recruiting
Location: See location...
Intervention Type: Procedure
Study Type: Interventional
Study Phase: Not Applicable
SUMMARY
The aim of this clinical trial is to investigate the effect of different injection speeds on the spread of local anesthetic during ultrasound-guided erector spinae plane block (ESPB) in patients undergoing CT-guided lung nodule localization. The primary question addressed is whether a high injection speed (30 ml delivered within 30 seconds) produces a different local anesthetic distribution compared with a lower injection speed (30 ml delivered within 180 seconds).

Treatments
Other: Group C
A total of 30 ml of the local anesthetic solution (0.375% ropivacaine, comprising 15 ml ropivacaine and 15 ml iodinated contrast) is injected. In the Group C, the injection is administered within 180 seconds.
Experimental: Group S
A total of 30 ml of the local anesthetic solution (0.375% ropivacaine, comprising 15 ml ropivacaine and 15 ml iodinated contrast) is injected. In the Group S, the injection is administered within 30 seconds.
