A system and method to facilitate a stellate ganglion block or a pulsed radiofrequency procedure to treat post-traumatic stress disorder. The method can be fully automated and guided by a computer or the process can be guided by the surgeon. A computer including a central processing unit (CPU) is connected to a body scanning device and an injection mechanism. The body scanning device is used to read images of a patients body. The information collected from the images is transmitted to the CPU. A housing for the injection mechanism encloses syringes for delivery of an anesthetic and a clonidine mixture. After the anesthetic is injected into the patients skin from a first syringe, the housing is relocated by a connecting arm and a second syringe moves a needle into contact with the patients bone. An electric eye scans for blood before the clonidine mixture is injected by the second syringe.
