During the past 5 years of Operation Iraqi Freedom (OIF), a significant majority of the severe closed and penetrating head trauma has presented for definitive care at the National Naval Medical Center (NNMC) in Bethesda, MD, and at the Walter Reed Army Medical Center (WRAMC) in Washington, DC. The purpose of this article is to review our experience with this population of patients. ⋯ OIF has resulted in the highest concentration of severe closed and penetrating head trauma to return to NNMC and WRAMC since the Vietnam Conflict. Management scenarios were complex, incorporating principles designed to maximize outcomes in all body systems. Meaningful survival can potentially be achieved in a subset of patients with presenting GCS

Recent publications have dismissed the need for routine repeat computed tomography (CT) scans in patients with minimal brain injury (MBI) (Glasgow Coma Scale score 13-15 with positive initial CT) unless physical examination changes. In an attempt to better allocate scarce resources, we hypothesized that not only was repeat head CT unnecessary but also routine intensive care unit (ICU) monitoring of these patients with MBI and stable examinations were unnecessary. ⋯ Routine follow-up CT scans are beneficial in those patients with MBI and may lead to higher levels of medical management or neurosurgical intervention in patients with worsening CT findings. These patients should be kept in an ICU setting until head CT has stabilized. With these dissimilar results from previous studies, a prospectively randomized multicentered trial would be beneficial.

Extravasation of intravenous computed tomography scan contrast in blunt abdominal and pelvic trauma.
Intravenous contrast extravasation (CE) on computed tomography (CT) scan in blunt abdominal trauma is generally regarded as an indication for the need for invasive intervention (either angiography or laparotomy). More recently, improvements in CT scan technology have increased the sensitivity in detecting CE, and, thus, we postulate that not all patients with this finding require intervention. ⋯ Although evidence of CE may suggest significant vascular injury, our data suggest that not all patients require invasive intervention. Further studies are needed to better define criteria for nonoperative management in patients with CE identified on their initial CT scan.

Helicopter transport of injured or ill patients in Operation Iraqi Freedom is a necessary but often high-risk endeavor. Our facility initiated a thorough process improvement and standardization initiative after several adverse outcomes. This report describes the results after this initiative, and evaluates the applicability of a civilian transport risk assessment tool to the combat environment. ⋯ Helicopter transport in a combat environment carries significant risk of adverse events because of the patient characteristics and inherent limitations of the transport platform. Strict attention to standardization, training, and process improvement is necessary to achieve optimal outcomes. The civilian TRS had lower discriminative ability in this military setting.

Midazolam, a short-acting benzodiazepine, is administered preoperatively and intraoperatively for amnesia and anxiolysis. Subsequently, patients often do not recall events which occurred while they were sedated. Recent studies have also reported retrograde facilitation after midazolam exposure. Posttraumatic stress disorder PTSD is based on memory of a traumatic event. Because of the concern that midazolam may enhance memory of the traumatic event in which soldiers were injured, we investigated the prevalence of PTSD in those burned soldiers who received perioperative midazolam and those who did not. We also investigated the intensity of the memories related to the traumatic event. ⋯ Rates of PTSD are not statistically different in combat casualties receiving midazolam during intraoperative procedures. Intraoperative midazolam is not associated with increased PTSD development or with increased intensity of memory of the traumatic event. Patients receiving midazolam had similar injuries (TBSA and ISS) and underwent a similar number of operations as those not receiving midazolam.
