Understanding what treatments may facilitate perioperative care of Veterans with posttraumatic stress disorder (PTSD) is of great importance to the U.S. health care system. Patients with PTSD are characterized by elevated central nervous system catecholamine concentrations and exaggerated and prolonged adrenergic responses to stress stimuli. At present, there are no data on the effects of perioperative beta blocker therapy in patients with PTSD, despite the rising significance of PTSD in Veteran populations. This prospective, double-blind study proposes to randomize 150 Veterans with PTSD scheduled for orthopedic, thoracic or vascular surgery at the San Francisco VA Medical Center to either a 14-day course of propranolol or placebo. This study will then follow these Veterans for a one-year period to evaluate the effects of the intervention on Veterans' surgical outcomes. The investigators hypothesize that patients with PTSD randomized to the propranolol group will demonstrate a reduced incidence of perioperative and postoperative morbidity and mortality.

The goal of this study is to evaluate the analgesic efficacy of bilateral erector spinae plane (ESP) blocks after lumbar and lumbo-sacral spine surgery by assessing postoperative pain scores and opiate requirements as the primary outcome measures. We are aiming to investigate how ESP blocks, performed under ultrasound guidance at the T12 vertebral level, contribute to postoperative pain control. This will be determined by measuring numerical rating pain scores repeatedly following surgery and opiate consumption until patient discharge from hospital. These primary outcome measures will be compared between a treatment group of participants, who will receive ESP blocks and a control group who will receive a sham block. Our primary hypothesis is that ESP blocks significantly reduce postoperative pain and opiate requirements
