Summary

The purpose of this study is to analyze the spread of local anesthetic using magnetic resonance imaging after thoracic 2 paravertebral block in patients with cervical radiculopathy.

Conditions

  • Cervical Spinal Stenosis

Interventions

PROCEDURE

Ultrasound probe sagittal group

Place the ultrasound probe vertically against the patient's spine and insert the needle in-plane. The width of insertion of the needle is usually approximately 5 cm from the midline. After the needle penetrates the superior costovertebral ligament and pops, when it reaches the thoracic paravertebral space, perform aspiration and inject 10 mL of 1% lidocaine. At this time, it can be observed in real time as the infusion fluid pushes the bright pleura away from the needle.

PROCEDURE

Ultrasound probe transverse group

Place the ultrasound probe transverse to the spine and insert the needle in-plane. The reflection of a transverse process is a common landmark. The needle goes in from lateral to in plane. The goal is a triangle between the parietal pleura anteriorly and the internal intercostal membrane and intercostal muscle posteriorly. The final point of the needle is the transition zone from the intercostal to the thoracic paraspinal space, just anterior to the transverse process. When it is confirmed that the tip of the needle has reached the paravertebral space, 10 mL of 1% lidocaine is injected after checking the negative pressure, and after confirming the spread of the drug in real time with ultrasound.
