A comparison cohort was made up of all patients (2,021 individuals) admitted to the trauma center between October 1, 2004, and September 30, 2005 prior to implementation of the antioxidant protocol. While pneumonia and renal failure were similar between the groups, the incidence of abdominal compartment syndrome was significantly less (90 versus 31), as were catheter-related infections (75 versus 50) and surgical site infections (101 versus 44). Pulmonary failure meaning the patient could not get off the ventilator was less as well (721 versus 528).

Dr. Cotton is now prescribing high-dose antioxidants only to the most seriously ill patients in the ICU, as they seem to derive the greatest benefit. He and his colleagues will now focus on dose adjustments and length of administration to see if the doses and duration they are currently using are optimal. They have been approached by several groups that are interested in collaborating and investigating these agents as part of multiinstitutional trials and expanding their use to critically ill nontrauma patients. 

"While we are all looking for that magic bullet to cure some of the horrible things that can happen after someone is injured or has an operation, we have something at our disposal," Dr. Cotton said. "It might not be that magic bullet, but it is a very inexpensive and safe way to reduce complications and mortality in the sickest patients."

Assisting Dr. Cotton with this study were Aviram Giladi, BS; Bryan R. Collier, DO, FACS; Lesly A. Dossett, MD; and Sloan B. Fleming, PharmD, all from Vanderbilt. He received no funding for this research.
