Brief 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. 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 or disease Intervention/treatment Phase
Herpes Zoster CRPS Other: supine extended position of the neck Not Applicable

Arm Intervention/treatment
Experimental: neck extended group
We measured the distances from cricoid cartilage to C6 or C7 transverse process in supine neutral and extended position of the neck.
 Other: supine extended position of the neck
we measure the distances from cricoid cartilage to C6 or C7 transverse process in supine neutral and extended position of the neck


Outcome Measures

Primary Outcome Measures :
  1. 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 :
  1. 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
