Clinical Trial Summary

This study will enroll patients meeting Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria for post-traumatic stress disorder (PTSD). Following an initial screening visit, clinical assessment, and enrollment, subjects will be randomized into treatment and placebo arms. Both cohorts will undergo a pre-intervention functional magnetic resonance imaging (fMRI) of their brain. Treatment subjects will receive unilateral two-level stellate ganglion block via ultrasound-guided injection of anesthetic (bupivacaine) into the cervical sympathetic tissue; placebo subjects will receive an identical volume of saline via the same procedures.

At approximately 4 weeks post-procedure, both cohorts will then undergo a post-intervention clinical assessment. Finally, both cohorts will undergo a post-intervention fMRI of their brain.

Intervention

Drug:
• Bupivacaine
At the C6 level, a total of 7cc of 0.5% bupivacaine will be injected slowly at this level, with negative aspiration every 2cc. The same procedure will be repeated at the C4 level directed towards the upper cervical ganglion ventral to the longus colli muscle with a total of 3cc of 0.5% bupivacaine.
• Saline
At the C6 level, a total of 7cc of saline control will be injected slowly at this level, with negative aspiration every 2cc. The same procedure will be repeated at the C4 level directed towards the upper cervical ganglion ventral to the longus colli muscle with a total of 3cc of saline control.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Skin Conductance Response (SCR) Amount	SCR will be reported as the number of sweat glads that are activated. The more emotionally aroused an individual is, the more the SCR amount is increased. SCR will be measured during three related viewing, learning, and choice tasks, quantified as the changes between the pre-intervention fMRI scan (visit 2) and the post-intervention fMRI scan (visit 5).	Week 2, Week 8
Primary	Change in Cerebral Blood Flow Levels	Blood flow levels will be obtained from Blood Oxygen Level Dependent (BOLD) fMRI signals during three related viewing, learning, and choice tasks, quantified as the changes between the pre-intervention fMRI scan (visit 2) and the post-intervention fMRI scan (visit 5).	Week 2, Week 8
Secondary	Posttraumatic Stress Disorder Checklist (PCL-5) Score	The PCL-5 is a 20-item self-report measure that assesses the 20 Diagnostic and Statistical Manual of Mental Disorders (DSM-5) symptoms of post-traumatic stress disorder (PTSD). The self-report rating scale is 0-4 for each symptom. Rating scale descriptors are the same: "Not at all," "A little bit," Moderately," "Quite a bit," and "Extremely." A total symptom severity score (range - 0-80) can be obtained by summing the scores for each of the 20 items; the higher the score, the more severe the PTSD symptoms.	Week 1

Secondary	Patient Health Questionnaire-9 (PHQ-9) Score	PHQ-9 consists of 9 items. Participants report how often they have been bothered by each item over the last 2 weeks with a score 0 (not at all) to 3 (nearly every day). The total score range is 0-27; the higher the score, the more severe the depression.	Week 1

Secondary	State-Trait Anxiety Inventory (STAI) - Form Y1 Score	STAI - Form Y1 is a commonly used measure of trait and state anxiety that consists of 20 statement which people have used to describe themselves.

Each item is scored from 1 (not at all characteristic of me) to 5 (entirely characteristic of me). The total score range is 12-60; the higher the score, the greater the intolerance of uncertainty.
