Purpose

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.

Condition	Intervention
Herpes Zoster CRPS	Other: supine extended position of the neck


Study Type:	Interventional
Study Design:	Intervention Model: Single Group Assignment Masking: None (Open Label) Primary Purpose: Treatment
Official Title:	Distances From Cricoid Cartilage to the Targets of Stellate Ganglion Block

Further study details as provided by jong bum Choi, Yonsei University:

Primary Outcome Measures:

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 ]
The distances from cricoid cartilage to C6, C7 transverse process will be measured in supine neural position and extended position of the neck up to 1 week after agreement to enroll

Secondary Outcome Measures:

the sexual difference in the distances from cricoid cartilage to C6, C7 transverse process in supine neutral or extended position of the neck [ Time Frame: up to 1 week ]
The sexual difference in the distances from cricoid cartilage to C6,C7 transverse process will be measured in supine neural position and extended position of the neck up to 1 week after agreement to enroll


Estimated Enrollment:	42
