what to expect
During the procedure
You will receive the Stellate Ganglion Block while you are awake, you will be asked to remove jewelry from around the head and neck area. An X-ray machine wil be used to locate the stellate ganglion and a small amount of local anesthetic will be injected to numb the treatment site. Using a Fluoroscopy, a type of x-ray, about 5cc of a long acting local anesthetic will be slowly injected into two areas of the stellate ganglion.
After the procedure
Do not drive or do any rigorous activity for 24 hours after your stellate ganglion block. Take it easy. You can return to your normal activities the next day. When your voice returns to normal, you may begin to sip water through a straw and gradually work up to eating solid foods.
What are the risk
The risk of complications from a stellate ganglion block is very low. However, there could be bruising or soreness at the injection site. Serious complications, including infection, bleeding and nerve damage, are uncommon.
preparing for your procedure
Clothing
Dress in loose, comfortable clothing, and leave jewelry and other valuables at home.
Driver
If at all possible, arrange for someone to drive you home. It is best if you do not have to deal with the stress of driving and traffic immediately after treatment
Fasting
If you are scheduled to be sedated, you must fast for 8 hours before the procedure.
Blood Thinners
Three days before your appointment, STOP taking fish oil and any blood thinners (such as Coumadin, Heparin, aspirin and ALL NSAIDS such as Advil, Motrin, etc.). The SGB treatment uses a medication that dilates blood vessels which, if paired with fish oil or blood thinners, could cause excessive bleeding and other complications.
