Abstract

Abstract: Co-occurrence of posttraumatic stress disorder (PTSD) and traumatic brain injury (TBI) symptoms are particularly prevalent in the special operations forces' community, along with other related conditions (e.g., endocrine dysregulation, sleep disorders, chronic pain). Ketamine infusion (KI) has been shown to increase neuroplasticity as well as memory improvement and cervical sympathetic block (CSB) has been shown to improve cognitive function, reduce sympathetic overactivity, and improve other symptoms of PTSD. We want to report the efficacious use of a single intervention consisting of bilateral CSB technique with subanesthetic KI X5 in a Special Operations Forces patient, diagnosed with PTSD with comorbid TBI, evaluated during treatment and at 1-year follow-up. We postulated KI and CSB would have a synergistic effect. Our patient received KI starting at 0.5 mg/kg, which was escalated daily. KI was combined with right-sided ultrasound-guided CSB (C6 and C4 levels). This was followed the next day by left-sided CSB and KI. Patient's PTSD symptoms were evaluated using the Posttraumatic Stress Disorder Checklist (PCL-5), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), suicidal ideation and other related factors by Concise Health Risk Tracking Self Report (CHRTSR). All measures were assessed prior to treatment, during treatment, and 394 days after. KI combined with CSB showed immediate and prolonged benefits 394 days later regarding the symptoms of PTSD, anxiety, depression, suicidal ideation, and cognitive deterioration (patient report). KI combined with CSB can markedly reduce symptoms of PTSD, psychiatric comorbidities, and cognitive dysfunction.
