Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The of epidurals and spinals, relies primarily on palpation of anatomic landmarks that are not always easy to find, More so, even after correct identification of palpable landmarks, Variability exists leading to performing neuraxial injection in undetermined intralaminar level. The most accurate method for identifying the interspace is the using of the fluoroscopy or CT technique, but exposure to radiation and availability make it unpractical in majority of cases. As ultrasound technology becomes more accessible to the clinician, it holds great potential to facilitate performing neuraxial anesthesia by the anesthesiologist in routine cases.

The aim of this study to compare the accuracy of identifying the intervertebral space, between manual palpation, versus ultrasound versus fluoroscopy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Neuraxial anesthesia relies upon a sound knowledge of anatomy to accurately direct needle placement both to achieve consistent success, and to avoid damage to other nearby structures. This prospective randomized study, will be performed in the pain management unit. We will assess patients who are scheduled to receive an epidural steroid injection. The investigator will request permission fro the ethics committee of Hadassah Medical Hospital.

Three anesthesiologist will perform this study, every one of the anesthesiologist will be asked to identify intralaminar space by one technique and we will compare the accuracy of the identifying of the intralaminar space.
