Ultrasound estimates of the epidural depth in the paramedian sagittal oblique and transverse median planes: the correlation between estimated and actual depth to the epidural space in children with scoliosis
Authors' conclusion
The PSO view can be a reliable guide to facilitate epidural puncture in children with scoliosis with better visualization.
Study context
- Population
- Children aged 3–14 years with thoracolumbar scoliosis (Cobb angle >10°) requesting postoperative epidural analgesia
- Participants
- 55 children
- Exposure
- Ultrasound epidural depth estimation in the paramedian sagittal oblique (PSO) vs transverse median (TM) plane
- Outcome
- Correlation and agreement between ultrasound-estimated and actual epidural depth (Pearson's and concordance correlation coefficients)
Main finding
As reported in the abstract
Correlation of ultrasound-estimated vs actual epidural depth
| Group | Pearson's correlation coefficient | Concordance correlation coefficient |
|---|---|---|
| PSO | 0.964 | 0.952 |
| TM | 0.930 | 0.892 |
Pearson's correlation coefficient
PSO0.964
