Updated Findings on the Efficacy of Combined Subanesthetic Ketamine Infusion and Cervical Sympathetic Blockade as a Symptomatic Treatment of PTSD/TBI in a Special Forces Patient with a 2-year Follow-up: A Case Report.

Posttraumatic stress disorder (PTSD)/blast traumatic brain injury (bTBI) in a Special Operations Forces (SOF) cohort has been shown to be successfully treated using a cervical sympathetic blockade (CSB)/ketamine infusion (KI) combination, termed the SOF method. In a prior case report, the patient was followed for 1 year. This report followed the same patient for a total of 720 days and found prolonged and sustained benefits with respect to PTSD and bTBI symptoms with further application of the SOF method.
