The purpose of this study was to 1. investigate the degree of agreement between the ultrasound-measured depth (in the transverse median and paramedian sagittal oblique plane) and the actual depth to the epidural space in pediatric patients with scoliosis. 2. investigate the quality of ultrasound view for detecting ligamentum flavum and dura mater.
Study Type
OBSERVATIONAL
Enrollment
55
Using ultrasound with transverse median and paramedian sagittal oblique approach, the screens that show the target epidural space in the center are obtained and stored for evaluation.
Yonsei University Health System, Severance Hospital

the degree of agreement between the ultrasound-measured depth and the actual depth to the epidural space
the degree of agreement between the ultrasound-measured depth (in the transverse median and paramedian sagittal oblique plane) and the actual depth to the epidural space in pediatric patients with scoliosis.
Time frame: Ultrasound image, which is obtained before epidural Touhy needle insertion, will be evaluated within 1 week after epidural Touhy needle insertion
the quality of ultrasound view for detecting ligamentum flavum and dura mater (in the transverse median and paramedian sagittal oblique plane)
the quality of ultrasound view for detecting ligamentum flavum and dura mater (in the transverse median and paramedian sagittal oblique plane). Good: The distinction is clear and visible Fair: Visible by adjusting the probe Poor: Observation is difficult even when the probe is adjusted
Time frame: Ultrasound image, which is obtained before epidural Touhy needle insertion, will be evaluated within 1 week after epidural Touhy needle insertion
