Distances From Cricoid Cartilage to the Targets of Stellate Ganglion Block
A study testing supine extended position of the neck in people with Herpes Zoster and CRPS, run by Yonsei University at 1 site in South Korea.
Trial summary
Stellate ganglion block targets are C6 transverse process or C7 transverse process in anterior paratracheal approach which is most popular method. Cricoid cartilage is known that it is located at C6 level in supine neutral position of the neck. Read more about this study

About this study
Stellate ganglion block targets are C6 transverse process or C7 transverse process in anterior paratracheal approach which is most popular method. Cricoid cartilage is known that it is located at C6 level in supine neutral position of the neck. But stellate ganglion block is performed in supine extended position of the neck. So cricoid cartilage will move up to cephalad direction and pain doctors should find C6 or C7 transverse process at lower neck area than cricoid cartilage.

The record says: status not confirmed, as of the sponsor's last update on 24 Jan 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

How can a doctor refer a patient or contact the research team?
Contact Jong B Choi (82-2-2019-6093, romeojb@naver.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
the distances from cricoid cartilage to C6, C7 transverse process in supine neutral and extended position of the neck (time frame: up to 1 week). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
