A fundamental requirement for the safe and effective performance of paravertebral blockade is reliable estimates of the depth from skin to paravertebral space at different thoracic levels. This distance was assessed using a nerve stimulator guided paravertebral blockade technique in 527 separate blocks in 186 patients scheduled for various surgical procedures on the trunk. The median skin-paravertebral depth was 55.0 mm. The skin-paravertebral distance at upper (T1-3) and lower (T9-12) thoracic levels were significantly greater than mid-thoracic levels (T4-8) (p < 0.05). Body mass index significantly influences this depth at upper and lower thoracic levels (p < 0.001) but not in the mid-thoracic region.
椎旁阻滞安全有效实施的一项基本要求是可靠估计不同胸段水平从皮肤到椎旁间隙的深度。在186例计划进行躯干各种外科手术的患者中，采用神经刺激器引导的椎旁阻滞技术对527次独立阻滞进行了该距离评估。皮肤至椎旁的中位深度为55.0毫米。胸段上部（T1 - 3）和下部（T9 - 12）水平的皮肤至椎旁距离显著大于胸段中部水平（T4 - 8）（p < 0.05）。体重指数对上胸段和下胸段水平的该深度有显著影响（p < 0.001），但对胸段中部区域无影响。
