The lumbar epidural space in pregnancy: visualization by ultrasonography -- Grau et al. 86 (6): 798 -- British Journal of Anaesthesia

  • During pregnancy, the optimum puncture site available on the skin for epidural space cannulation was smaller, the soft-tissue channel between the spinal processes was narrower, and the skin–epidural space distance was greater. The epidural space was narrower and deformed by the tissue changes. The visibility of the ligamentum flavum, of the dura mater and of the epidural space decreased significantly during pregnancy.
