Aortic intimal injuries from blunt trauma: resolution profile in nonoperative management.

OBJECTIVE: To provide preliminary data on the resolution profile of aortic intimal injuries treated nonoperatively and on the safety of nonoperative management of these injuries. METHODS: Five blunt trauma patients diagnosed by transesophageal echocardiography (TEE) with traumatic intimal injury of the aorta were assigned to nonoperative management. This included beta-blockade to maintain systolic blood pressure between 80 and 90 mm Hg and heart rate between 60 and 80 beats/min, serial TEE studies, and invasive monitoring in the intensive care unit. The evolution of injury, the effectiveness of nonoperative treatment, and the potential need for an operative intervention were monitored. RESULTS: The patients had a mean Injury Severity Score of 32 and sustained multiple associated thoracic and extrathoracic injuries. Aortic injuries were located at the level of the ligamentum arteriosum and in the descending aorta adjacent to the diaphragm in three and two patients, respectively. The mean size of injury was 12.5 mm (range, 5-20 mm) and a thrombus attached to the endothelium was present in three of the five patients. Complete resolution of injury occurred within 9.4 +/- 6.6 days (range, 3-19 days). All patients remained hemodynamically stable and adequately perfused. All demonstrated progressive resolution of their aortic intimal injuries. No complications related to the aortic injuries were identified during a mean follow-up of 16.8 months. CONCLUSION: This small series suggests that aortic intimal injuries smaller than 20 mm in hemodynamically stable patients treated with beta-blockade resolve within several days. This approach appears safe when monitored by serial TEE studies performed by experienced experts, and continuous invasive hemodynamic monitoring.

The profile of level I trauma center directors.

BACKGROUND: No data are available regarding the characteristics of the trauma directors of Level I trauma centers. METHODS: Questionnaires were mailed to 102 directors of Level I trauma centers. Data were analyzed in a blinded fashion. RESULTS: Seventy-two directors responded. All were men, with a mean age of 48 +/- 6 years. Fifty-eight percent of directors were fellowship trained. Directorship was assumed 7.3 +/- 6.1 years after training and the average time on the job was 8.6 +/- 6.1 years. Directors work in urban (93%), university-affiliated (67%) institutions that admit 1,000 to 2,000 patients annually (50%). Practice time distribution is as follows: trauma clinical care, 33%; general surgery, 20%; administrative work, 18%; critical care delivery, 17%; and research, 11%. Directors take 6.6 +/- 2.2 night calls per month, with half of them taking in-house call. Eighty-eight percent of directors are involved in research. Seventy-eight percent of directors earn $200,000 to $325,000 per year, with the largest group making $225,000 to $250,000. Salary is derived from clinical revenues (42%) and hospital (37%) or university (20%) support. Compensation is higher in community hospitals and tends to be higher in the Midwest. CONCLUSION: The profile of the trauma director at a Level I trauma center was described. This may be important in trauma career and systems development.

Characterization of a murine model of endotoxin-induced acute lung injury.

Endotoxin-induced microvascular lung injury in mice is a commonly used experimental model of the acute respiratory distress syndrome (ARDS). The present paper aimed to characterize this popular model in a comprehensive and systematic fashion. Male C57bl/6 mice (n = 5) were administered an LD55 dose of E. coli endotoxin (15 mg/kg, i.p.), and lungs were harvested at several time points and evaluated for injury as well as for expression of a variety of inflammatory mediators. Endotoxin induced many features characteristic of acute microvascular lung injury. These included early (1-2 h) expression of inflammatory mediators (IL-1alpha, IL-1beta, IL-4, IL-6, IL-10, TNF-alpha, interferon-alpha, interferon gamma, and MCP-1) and leukocyte accumulation in lung tissue (lung myeloperoxidase activity 18.5 +/- 7.8 U/g tissue, P < 0.05), followed by pulmonary edema (lung water content index 17.4% +/- 2.5%, P < 0.05) and mortality. Histopathological evaluation of lung tissue was compatible with these findings. The characterization of this murine model of endotoxin-induced microvascular injury will facilitate its utilization in ARDS research.

MOB-1 and TNF-alpha interact to induce microvascular lung injury.

We have recently identified the alpha-chemokine mob-1 as a highly inducible gene in several rat models of microvascular lung injury, whose expression was suppressed by inhibition of tumor necrosis TNF-alpha (TNF-alpha). This work provides further insight into the relationship between mob-1 and TNF-alpha in the development of lung injury assessed by pulmonary edema and leukosequestration. First, pulmonary mob-1 and TNF-alpha were upregulated in animals subjected to lung injury produced by the intratracheal administration of recombinant TNF-alpha and recombinant mob-1, respectively. Second, mob-1 inhibition by intratracheal anti-mob-1 antibody attenuated lung injury induced by recombinant TNF-alpha. Third, pretreatment with anti-TNF-alpha monoclonal antibody administered intratracheally abrogated recombinant mob-1-induced microvascular lung injury. In vitro, mob-1 and TNF-alpha increased each other's production in RAW 264.7 cells and mob-1 or TNF-alpha inhibition prevented endotoxin-induced upregulation of TNF-alpha or mob-1, respectively, from these cells. Together, these data suggest that mob-1 and TNF-alpha interact to promote lung inflammation.

Evaluation of an emergency radiology quality assurance program at a level I trauma center: abdominal and pelvic CT studies.

PURPOSE: To evaluate the use of a redundant system in improving quality of care in the trauma setting by examining a subset of our quality assurance program. MATERIALS AND METHODS: Five hundred thirty-one consecutive abdominal and pelvic CT reports obtained in patients with trauma at a level I trauma center from August 22, 1999, to August 21, 2000, were retrospectively reviewed. Each case was initially interpreted by a board-certified or board-eligible radiologist during evaluation in the emergency department and was subsequently reviewed by a subspecialty abdominal imaging radiologist as part of a quality assurance program. Nineteen cases were excluded because available information was incomplete, resulting in 512 cases in the current study. Cases with discordant interpretations were followed up to discern care change. RESULTS: Of the 512 trauma cases, 153 (29.9%) showed discordant readings. Review of patient records demonstrated changes in patient care in 12 (7.8%) cases. Three (2.0%) cases were reviewed from the morbidity and mortality records of the Department of Trauma Surgery as a direct result of misinterpretations. Six (4%) cases involved additional diagnostic imaging for reevaluation; in four of these six cases the quality assurance reader's interpretation was confirmed, while in the other two, the initial interpretations were favored. CONCLUSION: Findings suggest that discordant radiologic interpretations most often do not result in a change in patient care and outcome. The quality assurance program did, however, identify and lead to changes in care in a number of cases by providing clinically important additional findings.
