Cervical Spinal Stenosis Clinical Trial
Official title:
A Magnetic Resonance Imaging Study of the Spread of Local Anesthetic Solution in Patients Receiving Ultrasound-guided Paravertebral Block at the Thoracic 2 Spinal Level: Prospective Randomized Controlled Study
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.
1. Ultrasound guided thoracic 2 paravertebral block will be done using sagittal scan or transverse scan. 2. Clinical parameters will be monitored (temperature, perfusion index, assessment of sensory block and analgesic effect, vital sign, adverse events) after the nerve block. 3. Cervical MRI will be taken 1 hour after the nerve block. 4. Follow up 7 days and 28 days after the MRI at outpatient clinic (numeric rating scale, medication quantification scale) ;
