Update on applied epidural anatomy - BJA Education
The epidural space contains the dural sac, spinal nerves, blood vessels, connective tissue and fat. The boundaries are summarised in Table 1 and the definitions of epidural regions in Table 2. 3 Cadaveric examination has shown that the contents, shape and physical environment of the epidural space vary depending on the region. There is ...
Comparison of the skin-to-epidural space distance at the …
2020年9月24日 · The objective of our study was to compare the distance from the skin to the epidural space (SED) at multiple levels, focusing on T 6-7, T 9-10, and L 2-3 using MRI.
2023年9月26日 · Dural puncture epidurals may safely improve detection of the epidural space. Some commonly encountered difficulties may be troubleshooted, whilst others require a new attempt. This tutorial covers the techniques to gain access to the epidural space.
The epidural space is bounded supe riorly by the fusion of the sp inal and periosteal layers of the dura mater at the foramen magnum. Inferiorly, it is bound by the sacrococcygeal
Epidural Space - an overview | ScienceDirect Topics
The distance from the skin to the epidural space in normal adults usually ranges from 3 to 5 cm. In the mid-lumbar region, the depth of the posterior epidural space is about 5 to 6 mm, and it gradually decreases to 2 mm at the S1 level. The epidural space is widest in the midline below the junction of the lamina and it narrows laterally.

2012年11月1日 · Three-dimensional diagram demonstrating segmented nature of the epidural space. (a) Posterior segment of epidural space; (b) epidural fat in intervertebral foramina; (c) dural sac in spinal canal. (From Hogan 23).
Results: The proposed equation relates skin surface to epidural space distance with the Body Mass Index (BMI). Illustrations and computational experiments demonstrate propositions quality. Conclusion: More universal equations for estimate dis-tance from skin to epidural space in parturients are pro-

2005年6月1日 · Epidural space. The boundaries of the epidural space are summarized in Table 1 and the definitions of the cervical, thoracic, lumbar and sacral regions are defined in Table 2. The epidural space contains fat, the dural sac, spinal nerves, blood vessels and connective tissue .
A Novel Actuator for Simulation of Epidural Anesthesia and Other …
For a midline approach to the epidural space, the clinician advances the needle between the spinous processes at the appropriate vertebral level. The needle must pass through five distinct tissue layers: Skin, subcutaneous fat, supraspinous ligament, interspinous ligament, and ligamentum flavum.
Epidural space: Anatomy and function - Kenhub
2023年10月30日 · The term "epidural space" commonly denotes the area between the dura mater, the outermost layer of the spinal meninges, and the inner surface of the vertebral canal. However, the term is also used to describe the extradural space of the cranial cavity, which typically exists as a potential space.
