Fracture locations influence the likelihood of rectal and lower urinary tract injuries in patients sustaining pelvic fractures.

BACKGROUND Rectal and lower urinary tract injuries in pelvic fractures can lead to significant complications. We sought to determine whether fracture locations could serve as markers for injury. METHODS In our retrospective review of patients with blunt pelvic fractures, the association of fracture locations with injury to the rectum, bladder, and urethra was explored with Fishers exact test and subsequently analyzed with multiple logistic regression. RESULTS Of the 362 patients reviewed, 8 had rectal injury and 24 had lower urinary tract injury. The following locations were found to be significant. Rectum: symphysis pubis (relative risk [RR] = 3.3, p < 0.001) and sacroiliac (SI) joint (RR = 2.1, p = 0.014). Bladder: symphysis pubis (RR = 2.1, p < 0.001), SI joint (RR = 2.0, p < 0.001), and sacrum (RR = 1.6, p = 0.002). Urethra: symphysis pubis (RR = 2.9, p = 0.003), SI joint (RR = 1.8, p = 0.04), and inferior ramus (RR = 4.6, p = 0.008). After multivariate analysis, the primary and independent predictors for each of the injuries were as follows: rectal injury, widened symphysis; bladder injury, widened symphysis and SI joint; and urethral injury, widened symphysis and fracture of the inferior pubic ramus. Although these associations were significant, the overall prevalence of associated rectal and urologic injuries was low. Consequently, the predictive values of these radiologic findings were also low, ranging from 5% to 9% for urethral and rectal injuries to 20% for bladder injuries. CONCLUSION Certain fracture locations are associated with increased risk for rectal, bladder, or urethral injury. Fractures involving these locations should prompt further work-up for assessment.

Emergency room thoracotomy for penetrating chest injury: effect of an institutional protocol.

BACKGROUND Emergency room thoracotomy (ERT) can be life saving in patients with penetrating chest injury. A protocol was established at our institution stating that ERT be performed for cases of cardiac tamponade secondary to penetrating chest trauma on patients with vital signs/mentation in the field or on arrival to the emergency room. To validate our protocol, we reevaluated patients undergoing ERT at our institution. METHODS In our retrospective review, there were 49 patients undergoing ERT over a 6-year period. RESULTS Survival in patients with vital signs was approximately 50%. Survival in those without was 0%. Compared with the preprotocol data, the number of ERTs declined from 32.2 cases per year to 8.1 cases per year. Overall survival increased from 4% to 20%. Neurologic outcome remained unchanged. CONCLUSION We believe that the data validate our protocol, and the establishment of a guideline has enabled us to maximize patient survival and minimize exposure risks to our staff.

Severe complicated Clostridium difficile infection: Can the UPMC proposed scoring system predict the need for surgery?

INTRODUCTION Clostridium difficile infection (CDI) is one of the most common health care–associated infections, and it continues to have significant morbidity and mortality. The onset of fulminant colitis often requires total abdominal colectomy with ileostomy, which has a mortality rate of 35% to 57%. University of Pittsburgh Medical Center (UPMC) developed a scoring system for severity and recommended surgical consultation for severe complicated disease. The aim of this study was to evaluate if the UPMC-proposed scoring system for severe complicated CDI can predict the need for surgical intervention. METHODS This is a retrospective review of all patients who developed severe complicated CDI at Geisinger Medical Center between January 2007 and December 2012 as defined by the UPMC scoring system. Main outcomes were the need for surgical intervention and 30-day mortality. RESULTS Eighty-eight patients had severe complicated CDI based on the UPMC scoring system. Fifty-nine patients (67%) required surgery and 29 did not. All patients had a diagnosis of CDI as shown by positive toxin assays. There was no difference between the groups with respect to age, sex, body mass index, or comorbidities. When comparing the surgical group to the nonsurgical cohort, the surgical cohort averaged 20 points on the scoring system compared to 9 in the nonoperative cohort. In patients with severe complicated CDI, 15 or more points predicted the need for surgery 75% of the time. Forty-two percent of the surgical cohort had respiratory failure requiring mechanical ventilation compared to 0% in the nonsurgical cohort (p < 0.0001). Forty-nine percent of the surgical cohort required vasopressors for septic shock before surgery compared to 0% in the nonsurgical cohort (p < 0.0001). Acute kidney injury was present in 92% of the surgical cohort versus 72% within the nonsurgical cohort (p = 0.026). Seventy-six percent of the surgical patients were admitted to the ICU before surgery. Within the nonsurgical cohort, only 24% of patients required ICU stay during admission. Overall, 30-day mortality in the surgical cohort was 30%, and there was no mortality in the nonsurgical cohort. CONCLUSIONS The UPMC scoring system for severe complicated CDI can help us predict patients who need a surgical consult and the need for surgical intervention. In patients with severe complicated CDI, evidence of end-organ failure predicts surgical intervention. LEVEL OF EVIDENCE Prognostic study, level III; therapeutic study, level IV.

Utility of Prophylactic Antibiotics in Nonoperative Facial Fractures.

AbstractFacial fractures are commonly managed nonoperatively. Patients with facial fractures involving sinus cavities commonly receive 7 to 10 days of prophylactic antibiotics, yet no literature exists to support or refute this practice. The aim of this study was to compare the administration and duration of antibiotic prophylaxis on the incidence of soft tissue infection in nonoperative facial fractures. A total number of 289 patients who were admitted to our level I trauma center with nonoperative facial fractures from the beginning of 2012 to the end of 2014 were studied. Patients were categorized into 3 groups: no antibiotic prophylaxis, short-term antibiotic prophylaxis (1–5 days), and long-term antibiotic prophylaxis (>5 days). The primary outcome was the incidence of facial soft tissue infection and Clostridium difficile colitis. Fifty patients received no antibiotic prophylaxis. Sixty-three patients completed a short course of antibiotic prophylaxis and 176 patients received long-term antibiotics. Ampicillin/sulbactam, amoxicillin/clavulanic acid, or a combination of both were used in 216 patients. Twenty-three patients received clindamycin due to penicillin allergy. Short and long courses of antibiotic prophylaxis were administered more commonly in patients with concomitant maxillary and orbital fractures (P <0.0001). No mortality was found in any group. Soft tissue infection was not identified in any patient. C. difficile colitis was identified in 1 patient who had received a long course of antibiotic prophylaxis (P = 0.7246). There was no difference in the outcome of patients receiving short-term, long-term, and no antibiotic prophylaxis. Prospective randomized studies are needed to provide further clinical recommendations.
