Emergency Computed Tomography Angiogram of the Chest, Abdomen, and Pelvis

In the setting of blunt trauma, the rapid assessment of internal injuries is essential to prevent potentially fatal outcomes. Computed tomography is a useful diagnostic tool for both screening and diagnosis. In addition to trauma, acute chest syndromes often warrant emergent computed tomographic angiography, looking for etiologies such as aortic aneurysms or complications of aortic aneurysms, or both, pulmonary emboli, as well as other acute vascular process like aortic dissection and Takayasu aortitis. With continued improvements in diagnostic imaging, computed tomographic angiography of the chest, abdominal and pelvis proves to be an effective modality to image the aorta and other major vascular structures

Pregnancy is Not a Sufficient Indicator for Trauma Team Activation

BACKGROUND: Trauma complicates 6% to 7% of all pregnancies. Adverse outcomes are rare when monitoring is normal and early warning signs absent. Trauma systems often use pregnancy as the sole criterion (PSC) for partial trauma team activation. This study compares outcomes of pregnant patients presenting with PSC versus other physiologic, mechanistic, or anatomic (OPMA) activation criteria. METHODS: Three hundred fifty-two consecutive obstetric partial trauma team activation patients (2000-2005) were grouped by length of gestation and evaluated for activation criteria and early maternal and fetal outcomes. Data were analyzed using descriptive statistics and analysis of variance. RESULTS: Patients ranged in age from 16 to 44 (mean age, 28 +/- 6.4) and in weeks gestation between 1 and 40 weeks (mean, 25 +/- 8 weeks). Eighty-two percent had been in vehicle crashes. One hundred eighty-eight (58%) were activated based on PSC and 137 on OPMA. No PSC patient had injuries sufficient to warrant trauma service admission. Ninety-four percent of all PSCs of \u3c20 weeks were discharged home from the emergency department. There were no maternal mortalities. There were four fetal mortalities; two pregnancies were terminally compromised before the trauma event. No patient in the PSC group required admission to the trauma service. There were seven cases of abruption (2%) and 18 cases of vaginal bleeding or discharge (6%). No case of vaginal bleeding or abruption in the first 20 weeks was hypotensive at the scene or on arrival. CONCLUSION: In this study, pregnancy was not an independent predictor of the need for trauma team activation. Standard OPMA trauma activation criteria apply equally to pregnant and nonpregnant patients. These data provide support for more judicious allocation of scarce trauma systems resources

Intravenous vs. oral hydration administration for optimal ureteral opacification in computer tomographic urography

PURPOSE: Computed tomographic urography (CTU) is the gold standard in the radiologic detection of urinary tract disease. The goals of CTU protocols are to garner fully distended and opacified collecting systems, ureters, and bladder for adequate evaluation. Multiple techniques have been reported in the literature to optimize urinary tract visualization and enhance genitourinary assessment. However, currently no strict guidelines exist regarding the preferred method for optimal urinary tract opacification in CTU. MATERIALS AND METHODS: During the year 2013, a retrospective chart review of CTU examinations were done at either an academic institution where IV hydration was routinely administered or at an outpatient imaging center where oral hydration was preferred. Two attending radiologists experienced in cross-sectional body imaging, retrospectively reviewed all the images, blinded to the method of hydration. The reviewers were asked to quantify ureteral distension as well as to grade urinary tract opacification. RESULTS: A total of 176 patients and 344 ureters were analyzed. Mean maximal ureteral widths were largest in the mid ureter, followed closely by the proximal ureter. Mean opacification scores showed no statistical significance between hydration methods, stratified by ureteral segment. CONCLUSION: Our study results show that oral hydration is easy to implement, produces ureteral distention and opacification similar to CTU studies with IV hydration, without loss of diagnostic quality in our select patient population. Although not statistically significant, the oral hydration protocol is more cost effective, requires less hospital resources, and may be a useful step toward cost-containment strategies pertinent in today\u27s healthcare landscape
