Evaluation and Management of Blunt Traumatic Aortic Injury: A Practice Management Guideline from the Eastern Association for the Surgery of Trauma

BACKGROUND Blunt traumatic aortic injury (BTAI) is the second most common cause of death in trauma patients. Eighty percent of patients with BTAI will die before reaching a trauma center. The issues of how to diagnose, treat, and manage BTAI were first addressed by the Eastern Association for the Surgery of Trauma (EAST) in the practice management guidelines on this topic published in 2000. Since that time, there have been advances in the management of BTAI. As a result, the EAST guidelines committee decided to develop updated guidelines for this topic using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework recently adopted by EAST. METHODS A systematic review of the MEDLINE database using PubMed was performed. The search retrieved English language articles regarding BTAI from 1998 to 2013. Letters to the editor, case reports, book chapters, and review articles were excluded. Topics of investigation included imaging to diagnose BTAI, type of operative repair, and timing of operative repair. RESULTS Sixty articles were identified. Of these, 51 articles were selected to construct the guidelines. CONCLUSION There have been changes in practice since the publication of the previous guidelines in 2000. Computed tomography of the chest with intravenous contrast is strongly recommended to diagnose clinically significant BTAI. Endovascular repair is strongly recommended for patients without contraindications. Delayed repair of BTAI is suggested, with the stipulation that effective blood pressure control must be used in these patients.

Blunt cerebrovascular injury screening guidelines: what are we willing to miss?

BACKGROUND Blunt cerebrovascular injury (BCVI) is reported to occur in approximately 2% of blunt trauma patients, with a stroke rate of up to 20%. Guidelines for BCVI screening are based on clinical and radiographic findings. We hypothesized that liberal screening of the neck vasculature, as part of initial computed tomographic (CT) imaging in blunt trauma patients with significant mechanisms of injury, identifies BCVI that may go undetected. METHODS As per protocol, patients at risk for significant injuries undergo a noncontrast head CT scan followed by a multislice CT scan (40-slice or 64-slice) incorporating an intravenous contrast-enhanced pass from the circle of Willis through the pelvis (whole-body CT [WBCT] scan). The trauma registry was retrospectively reviewed, and all patients with BCVI from 2009 to 2012 were analyzed. Patients undergoing WBCT scan were then identified, and records were reviewed for BCVI indicators (skull base fracture, cervical spine injury, displaced facial fracture, mandible fracture, Glasgow Coma Scale score ⩽ 8, flexion mechanism, hard signs of neck vascular injury, or focal neurologic deficit). RESULTS Of 16,026 patients evaluated during the study period, 256 (1.6%) were diagnosed with BCVI. The population consisted of 185 patients with suspected BCVI after WBCT scan. One hundred twenty-nine patients (70%) had at least one indicator for BCVI screening, while 56 (30%) had no radiographic or clinical risk factors; 48 of the 56 patients underwent confirmatory CT angiography of the neck within 71 hours of initial WBCT scan, with 35 patients having 45 injuries. CONCLUSION More liberalized screening for BCVI during initial CT imaging in trauma patients clinically judged to have sufficient mechanism is warranted. Using current BCVI screening guidelines leads to missed BCVI and risk of stroke. LEVEL OF EVIDENCE Diagnostic study, level III.

Nontrauma open abdomens: A prospective observational study.

BACKGROUND Damage-control surgery with open abdomen (OA) is described for trauma, but little exists regarding use in the emergency general surgery. This study aimed to better define the following: demographics, indications for surgery and OA, fascial and surgical site complications, and in-hospital/long-term mortality. We hypothesize that older patients will have increased mortality, patients will have protracted stays, they will require specialized postdischarge care, and the indications for OA will be varied. METHODS A prospective observational study of emergency general surgery OA patients from June 2013 to June 2014 was performed. Demographics, clinical/operative variables, comorbidities, indications for procedure and OA, wound/fascial complications, and disposition were collected. Patients were stratified into age groups (⩽60, 61–79, and ≥80 years). Six-month and 1-year mortality was determined by query of the Social Security Death Index. RESULTS A total of 338 laparotomies were performed, of which 96 (28%) were managed with an OA. Median age was 61 years (interquartile range [IQR], 0–68 years), and 51% were male. The median Charlson Comorbidity Index was 2 (IQR, 1.5–5.1), and the median hospital stay was 25 days (IQR, 15–50 days). The most common indications for operation were perforated viscus/free air (20%), mesenteric ischemia (17%), peritonitis (16%), and gastrointestinal hemorrhage (12%). The most common indication for OA was damage control (37%). In the 63 patients with fascial closure, there were 9 (14%) wound infections and 6 (10%) fascial dehiscences. A total of 30% of the patients died in the hospital, and an additional six patients died 6 months after discharge. Patients in the oldest age stratum were more likely to die at 6 months than those in the lower strata. CONCLUSION Older patients were more likely to die by 6 months, the median hospital stay was 3 weeks, and there were multiple indications for OA management. With a 6-month mortality of 36% and 70% of survivors requiring postdischarge care, this population represents a critically ill population meriting additional study.

Angiographic embolization for hemorrhage following pelvic fracture: Is it "time" for a paradigm shift?

Introduction Major pelvic disruption with hemorrhage has a high rate of lethality. Angiographic embolization remains the mainstay of treatment. Delays to angiography have been shown to worsen outcomes in part because time spent awaiting mobilization of resources needed to perform angiography allows ongoing hemorrhage. Alternative techniques like pelvic preperitoneal packing and aortic balloon occlusion now exist. We hypothesized that time to angiographic embolization at our Level 1 trauma center would be longer than 90 minutes. Methods A retrospective review was performed of patients with pelvic fracture who underwent pelvic angiography at our trauma center over a 10-year period. The trauma registry was queried for age, sex, injury severity score, hemodynamic instability (HI) on presentation, and transfusion requirements within 24 hours. Charts were reviewed for time to angiography, embolization, and mortality. Results A total of 4712 patients were admitted with pelvic fractures during the study period, 344 (7.3%) underwent pelvic angiography. Median injury severity score was 29. Median 24-hour transfusion requirements were five units of red blood cells and six units of fresh frozen plasma. One hundred fifty-one patients (43.9%) presented with HI and 104 (30%) received massive transfusion (MT). Median time to angiography was 286 minutes (interquartile range, 210–378). Times were significantly shorter when stratified for HI (HI, 264 vs stable 309 minutes; p = 0.003), and MT (MT, 230 vs non-MT, 317 minutes; p < 0.001), but still took nearly 4 hours. Overall mortality was 18%. Hemorrhage (35.5%) and sepsis/multiple-organ failure (43.5%) accounted for most deaths. Conclusion Pelvic fracture hemorrhage remains a management challenge. In this series, the median time to embolization was more than 5 hours. Nearly 80% of deaths could be attributed to early uncontrolled hemorrhage and linked to delays in hemostasis. Earlier intervention by Acute Care Surgeons with techniques like preperitoneal packing, aortic balloon occlusion, and use of hybrid operative suites may improve outcomes.

Acute Care Surgery: Defining the Economic Burden of Emergency General Surgery

BACKGROUND Trauma centers (TCs) have been shown to provide lifesaving, but more expensive, care when compared with non-TCs (NTC). Limited data exist about the economic impact of emergency general surgery (EGS) patients on health care systems. We hypothesized that the economic burden would be higher for EGS patients managed at TCs vs NTCs. METHODS The Maryland Health Services Cost Review Commission database was queried from 2009 to 2013. The American Association for the Surgery of Trauma EGS ICD-9 codes were used to define the top 10 EGS diagnoses. Demographic characteristics, TC designation, severity of illness, and hospital charge data were collected. Differences in total charges between TCs and NTCs were analyzed by Wilcoxon test using SAS 9.3 software (SAS Institute). RESULTS A total of 435,623 patients were included. Median age was 61 years (interquartile range 47 to 76 years) and 55.9% were female. Median length of stay was 4 days; 90.3% were admitted via emergency department; and overall mortality was 5.1%. Overall median charges were
