ABSTRACT
ABSTRACT: Blunt cardiac injury (BCI) describes a spectrum of problems including severe, potentially life-threatening injuries from trauma. Pericardial effusion is an example of a BCI that has generally been assumed to imply serious underlying injury to the heart and should be considered hemopericardium until proven otherwise. A standard of care has been established to screen for BCI and treat hemodynamically unstable patients with an acute pericardial effusion presumably related to BCI. Less agreement exists on definitive treatment for hemodynamically stable patients with pericardial effusion after blunt cardiac trauma. This case study explores a new treatment for small to moderate hemopericardium in a stable patient after BCI.

BACKGROUND: The American Association for the Surgery of Trauma (AAST) has developed a grading system for emergency general surgery (EGS) conditions. We sought to validate the AAST EGS grades for patients undergoing urgent/emergent colorectal resection. METHODS: Patients enrolled in the "Eastern Association for the Surgery of Trauma Multicenter Colorectal Resection in EGS-to anastomose or not to anastomose" study undergoing urgent/emergent surgery for obstruction, ischemia, or diverticulitis were included. Baseline demographics, comorbidity severity as defined by Charlson comorbidity index (CCI), procedure type, and AAST grade were prospectively collected. Outcomes included length of stay (LOS) in-hospital mortality, and surgical complications (superficial/deep/organ-space surgical site infection, anastomotic leak, stoma complication, fascial dehiscence, and need for further intervention). Multivariable logistic regression models were used to describe outcomes and risk factors for surgical complication or mortality. RESULTS: There were 367 patients, with a mean (± SD) age of 62 ± 15 years. 39% were women. The median interquartile range (IQR) CCI was 4 (2-6). Overall, the pathologies encompassed the following AAST EGS grades: I (17, 5%), II (54, 15%), III (115, 31%), IV (95, 26%), and V (86, 23%). Management included laparoscopic (24, 7%), open (319, 87%), and laparoscopy converted to laparotomy (24, 6%). Higher AAST grade was associated with laparotomy (P = .01). The median LOS was 13 days (8-22). At least 1 surgical complication occurred in 33% of patients and the mortality rate was 14%. Development of at least 1 surgical complication, need for unplanned intervention, mortality, and increased LOS were associated with increasing AAST severity grade. On multivariable analysis, factors predictive of in-hospital mortality included AAST organ grade, CCI, and preoperative vasopressor use (odds ratio (OR) 1.9, 1.6, 3.1, respectively). The American Association for the Surgery of Trauma emergency general surgery grade was also associated with the development of at least 1 surgical complication (OR 2.5), while CCI, preoperative vasopressor use, respiratory failure, and pneumoperitoneum were not. CONCLUSION: The American Association for the Surgery of Trauma emergency general surgery grading systems display construct validity for mortality and surgical complications after urgent/emergent colorectal resection. These results support incorporation of AAST EGS grades for quality benchmarking and surgical outcomes research.

OBJECTIVE: Evidence comparing stoma creation (STM) versus anastomosis after urgent or emergent colorectal resection is limited. This study examined outcomes after colorectal resection in emergency general surgery patients. METHODS: This was an Eastern Association for the Surgery of Trauma-sponsored prospective observational multicenter study of patients undergoing urgent/emergent colorectal resection. Twenty-one centers enrolled patients for 11 months. Preoperative, intraoperative, and postoperative variables were recorded. χ, Mann-Whitney U test, and multivariable logistic regression models were used to describe outcomes and risk factors for surgical complication/mortality. RESULTS: A total of 439 patients were enrolled (ANST, 184; STM, 255). The median (interquartile range) age was 62 (53-71) years, and the median Charlson Comorbidity Index (CCI) was 4 (1-6). The most common indication for surgery was diverticulitis (28%). Stoma group was older (64 vs. 58 years, p < 0.001), had a higher CCI, and were more likely to be immunosuppressed. Preoperatively, STM patients were more likely to be intubated (57 vs. 15, p < 0.001), on vasopressors (61 vs. 13, p < 0.001), have pneumoperitoneum (131 vs. 41, p < 0.001) or fecal contamination (114 vs. 33, p < 0.001), and had a higher incidence of elevated lactate (149 vs. 67, p < 0.001). Overall mortality was 13%, which was higher in STM patients (18% vs. 8%, p = 0.02). Surgical complications were more common in STM patients (35% vs. 25%, p = 0.02). On multivariable analysis, management with an open abdomen, intraoperative blood transfusion, and larger hospital size were associated with development of a surgical complication, while CCI, preoperative vasopressor use, steroid use, open abdomen, and intraoperative blood transfusion were independently associated with mortality. CONCLUSION: This study highlights a tendency to perform fecal diversion in patients who are acutely ill at presentation. There is a higher morbidity and mortality rate in STM patients. Independent predictors of mortality include CCI, preoperative vasopressor use, steroid use, open abdomen, and intraoperative blood transfusion. Following adjustment by clinical factors, method of colon management was not associated with surgical complications or mortality. LEVEL OF EVIDENCE: Therapeutic study, level IV.

The American College of Surgeons Committee on Trauma requires that trauma centers with greater than 10 per cent injured patients admitted to non-trauma services (NTSs) have processes to review these for appropriateness of care. We previously described an algorithm to determine the appropriateness of NTS admissions. Our objective was to determine if the outcome and process of care was similar between TS- and NTS-admitted patients. We conducted a retrospective analysis of our trauma registry. NTS-appropriate patients by algorithm were included. Differences between patients admitted to a TS and an NTS were compared. Nine hundred forty-one patients met the algorithm criteria as appropriate for the NTS; 694 were admitted to TS and 247 to NTS. Contact with TS was the most common association with admission to TS. NTS patients were older and had similar Injury Severity Scores, and a similar proportion had three or greater pre-existing comorbidities. NTS-admitted patients had similar risk for mortality and complications, but longer length of stay, and were less likely to have a desirable discharge disposition. Minimally injured elderly patients constitute most of NTS and a large proportion of TS admissions. NTS admission seems appropriate with respect to mortality and complications. Differences in the care process may have accounted for longer length of stay and differences in disposition destination.

BACKGROUND: Occupational exposure is an important consideration during emergency department thoracotomy (EDT). While human immunodeficiency virus/hepatitis prevalence in trauma patients (0-16.8%) and occupational exposure rates during operative trauma procedures (1.9-18.0%) have been reported, exposure risk during EDT is unknown. We hypothesized that occupational exposure risk during EDT would be greater than other operative trauma procedures. METHODS: A prospective, observational study at 16 US trauma centers was performed (2015-2016). All bedside EDT resuscitation providers were surveyed with a standardized data collection tool and risk factors analyzed with respect to the primary end point, EDT occupational exposure (percutaneous injury, mucous membrane, open wound, or eye splash). Provider and patient variables and outcomes were evaluated with single and multivariable logistic regression analyses. RESULTS: One thousand three hundred sixty participants (23% attending, 59% trainee, 11% nurse, 7% other) were surveyed after 305 EDTs (gunshot wound, 68%; prehospital cardiopulmonary resuscitation, 57%; emergency department signs of life, 37%), of which 15 patients survived (13 neurologically intact) their hospitalization. Overall, 22 occupational exposures were documented, resulting in an exposure rate of 7.2% (95% confidence interval [CI], 4.7-10.5%) per EDT and 1.6% (95% CI, 1.0-2.4%) per participant. No differences in trauma center level, number of participants, or hours worked were identified. Providers with exposures were primarily trainees (68%) with percutaneous injuries (86%) during the thoracotomy (73%). Full precautions were utilized in only 46% of exposed providers, while multiple variable logistic regression determined that each personal protective equipment item utilized during EDT correlated with a 34% decreased risk of occupational exposure (odds ratio, 0.66; 95% CI, 0.48-0.91; p = 0.010). CONCLUSIONS: Our results suggest that the risk of occupational exposure should not deter providers from performing EDT. Despite the small risk of viral transmission, our data revealed practices that may place health care providers at unnecessary risk of occupational exposure. Regardless of the lifesaving nature of the procedure, improved universal precaution compliance with personal protective equipment is paramount and would further minimize occupational exposure risks during EDT. LEVEL OF EVIDENCE: Therapeutic/care management study, level III.

BACKGROUND: American College of Surgeons (ACS) verification is believed to provide benefits for trauma patients, but is associated with direct costs. STUDY DESIGN: We performed a 1-year retrospective review of the National Trauma Data Bank (NTDB) for 2012. Patients were separated into 3 age groups; Pediatric (PEDS), 0 to 14 years; adult, 15 to 65 years; and elderly (ELD), older than 65 years. We analyzed 2 injury severity cohorts, Injury Severity Score (ISS) 9 to 74 (ALL) and ISS 25 to 74 (MAJ). Multiple logistic regression to determine significance of ACS verification on mortality and major complications, controlling for age, ISS, shock, Glasgow Coma Scale, sex, age, comorbidities, and mechanism. Patients were excluded with an ISS <8 or equal to 75, dead on arrival, emergency department transfers, and burns. RESULTS: There were 392,997 patients: 262,644 in ACS centers and 130,353 in non-ACS centers. Distribution was: PEDS 3.8%, adults 64.5%, ELD 31.7%. For ALL adults, no differences were observed for primary outcome in ACS vs non-ACS centers (p = 0.128 and 0.061, for mortality and complications, respectively). For ALL PEDS and ELD, complications were more likely in non-ACS centers: (p = 0.003, odds ratio [OR] 2.61 [95% CI 1.36 to 5.0], and p < 0.0001, OR 3.17 [95% CI 2.21 to 4.56]). For MAJ trauma, death was more likely in adults in ACS vs non-ACS centers (p = 0.013, OR 0.82 [95% CI 0.71 to 0.96]). Complications for MAJ trauma were more likely in all age groups in non-ACS centers (adult: p = 0.028, OR 1.48 [95% CI 1.04 to 2.1]; ELD: p < 0.0001, OR 2.49 [95% CI 1.7 to 3.7]; PEDS: p < 0.0001, OR 4.29 [95% CI 2.13 to 8.69]). Length of stay was increased for all patients with complications (p < 0.0001). CONCLUSIONS: Measurable benefits in complications were observed in all age groups with MAJ trauma and in PEDS and ELD for ALL injury severity in ACS vs non-ACS trauma centers.

BACKGROUND: The objective is to examine the long-term survival status of geriatric trauma patients (GTPs) after major trauma. METHODS: A 10-year retrospective review at a Level I trauma center was performed. GTP were defined as age ≥ 65 years, with Injury Severity Score ≥ 30. Primary endpoints: survival at hospital discharge and long-term survival and discharge status. Two groups were defined: Abbreviated Injury Score (AIS) head >3 (G1, n = 116) and AIS head ≤ 3 (G2, n = 29). For GTP surviving hospitalization, two subgroups were defined: AIS head >3 (SG1, n = 77) and AIS head ≤ 3 (SG2, n = 20). Comparisons were analyzed for exploratory purposes only by independent t-tests or Mann-Whitney rank sums tests as appropriate. Long-term survival was plotted by a Kaplan-Meier curve. RESULTS: A total of 145 GTP met inclusion criteria. In-hospital mortality was 33%. Nonsurvivors had lower Glasgow Coma Scale score (6 vs. 14, p < 0.001), higher Injury Severity Score (38 vs. 34, p < 0.003), and lower Revised Trauma Score (5.97 vs. 7.84, p < 0.002). Hospital mortality for G1 was 34% (39 of 116) and for G2 was 31% (9 of 29). In group 1 (n = 116), 39 patients (34%) died while 77 (66%) survived a median of 29 months (interquartile range [IQR] = 6-62). In group 2 (n = 29), 9 patients (31%) died while 20 (69%) survived a median of 46.50 months (IQR = 26.75-79). For the 77 patients who were alive at discharge (subgroup 1, AIS >3), 25 (32%) died while 52 (68%) survived a median of 33 months (IQR = 10.50-72.75). For the 20 patients with AIS ≤ 3 (subgroup 2), 7 of 20 (35%) died while 13 (65%) survived a median of 49 months (IQR = 30.50-93.50). A total of 28 patients (19%) survived more than 5 years from the time of discharge. For these 65 GTPs who are currently alive at the time of follow-up, living status could be determined for 49 (75%) and 33 of 49 (67%) were living at home. CONCLUSIONS: This study documents appreciable long-term survival for GTP with major injury including severe head injury. A substantial proportion of these patients was able to return home. LEVEL OF EVIDENCE: III, prognostic/epidemiological study.

Given the increasing number of operational nuclear reactors worldwide, combined with the continued use of radioactive materials in both healthcare and industry, the unlikely occurrence of a civilian nuclear incident poses a small but real danger. This article provides an overview of the most important historical, medical, and scientific aspects associated with the most notable nuclear incidents to date. We have discussed fundamental principles of radiation monitoring, triage considerations, and the short- and long-term management of radiation exposure victims. The provision and maintenance of adequate radiation safety among first responders and emergency personnel are emphasized. Finally, an outline is included of decontamination, therapeutic, and prophylactic considerations pertaining to exposure to various radioactive materials.
ABSTRACT
The role of Emergency Medicine Physicians (EMP) in the care of trauma patients in North America has evolved since the advent of the specialty in the late 1980's. The evolution of this role in the context of the overall demands of the specialty and accreditation requirements of North American trauma centers will be discussed. Limited available data published in the literature examining the role of EMP's in trauma care will be reviewed with respect to its implications for an expanded role for EMPs in trauma care. Two training models currently in the early stages of development have been proposed to address needs for increased manpower in trauma and the critical care of trauma patients. The available information regarding these models will be reviewed along with the implications for improving the care of trauma patients in both Europe and North America.

BACKGROUND: Decreasing manpower available to care for trauma patients both in and out of the ICU has led to a number of proposed solutions, including increasing involvement of emergency medicine-trained physicians in the care of these patients. We performed a descriptive comparative study in an effort to define the role of fellowship-trained emergency medicine physicians as full-time traumatologists. STUDY DESIGN: We performed a retrospective review of concurrent and prospectively collected data comparing process of care and outcomes for the resuscitative phase of trauma patients cared for by full-time fellowship-trained trauma surgeons (TS), a fellowship-trained emergency medicine physician (ET), and a first-year fellowship-trained trauma surgeon (TS1). RESULTS: Patient age, Revised Trauma Score, and Injury Severity Score were similar between groups. Process of care, defined by transfusion of uncrossmatched blood, prevalence of hypotension in patients receiving uncrossmatched blood, time spent in the emergency department, frequency of ICU admission, severity of injury for ICU admission, and time between emergency department and operating room for patients requiring surgery, was equivalent between groups. Outcomes evaluated by mortality and length of stay in the hospital and ICU did not differ between groups, and provider group was not predictive of mortality in stepwise logistic regression. CONCLUSIONS: These data suggest that emergency traumatologists can provide trauma care effectively within a defined scope of practice and may provide an effective solution to manpower issues confronting trauma centers.

Systemic inflammatory response can be associated with clinically significant and, at times, refractory hypotension. Despite the lack of uniform definitions, this condition is frequently called vasoplegia or vasoplegic syndrome (VS), and is thought to be due to dysregulation of endothelial homeostasis and subsequent endothelial dysfunction secondary to direct and indirect effects of multiple inflammatory mediators. Vasoplegia has been observed in all age groups and in various clinical settings, such as anaphylaxis (including protamine reaction), sepsis, hemorrhagic shock, hemodialysis, and cardiac surgery. Among mechanisms thought to be contributory to VS, the nitric oxide (NO)/cyclic guanosine monophosphate (cGMP) pathway appears to play a prominent role. In search of effective treatment for vasoplegia, methylene blue (MB), an inhibitor of nitric oxide synthase (NOS) and guanylate cyclase (GC), has been found to improve the refractory hypotension associated with endothelial dysfunction of VS. There is evidence that MB may indeed be effective in improving systemic hemodynamics in the setting of vasoplegia, with reportedly few side effects. This review describes the current state of clinical and experimental knowledge relating to MB use in the setting of VS, highlighting the potential risks and benefits of therapeutic MB administration in refractory hypotensive states.

BACKGROUND: The autopsy remains the gold standard for evaluating traumatic deaths. The number of autopsies performed has declined dramatically. This study examines whether postmortem computed tomography ("CATopsy") can be used to determine cause of death in trauma patients. METHODS: Patients who presented to the trauma service and subsequently died within the first 24 hours of their hospitalization were prospectively enrolled. Any patient who underwent a major invasive procedure within this time frame was excluded. After pronouncement of death, each patient had a CATopsy performed, which was a noncontrast whole body scan. The patient then underwent an autopsy. These results were compared with those generated by the CATopsy. RESULTS: There were 12 patients enrolled in the study; average Injury Severity Scores was 33.5 +/- 19.0. In 10 of the 12 cases (83%), the CATopsy successfully indicated cause of death when compared with the autopsy. Seven of the 12 (58%) CATopsies demonstrated air in various parts of the circulatory system, including the heart in four cases. Five of the 12 (42%) patients had clinically significant findings (including the presence of an esophageal intubation) noted on the CATopsy not previously identified on any radiographic studies or on the autopsy. These findings were addressed as part of our performance improvement process. CONCLUSION: This study suggests that a postmortem imaging test, a CATopsy, can be used to determine cause of death in trauma patients. Beyond offering a noninvasive alternative to autopsy, it provides similar information to that provided in postmortem examination and may be used in trauma performance improvement activities.

Since the initial description of a concentrated outbreak of pneumocystis carnii pneumonia in 1981, the human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) pandemic has accounted for nearly 25 million deaths worldwide. This review focuses on estimations of prevalence by geographic region and identification of high-risk populations within each region, outcome for trauma patients with HIV and AIDS and risk management for health care workers who sustain occupational exposures. Trauma surgeons are more likely to encounter patients infected with HIV in geographic areas where HIV prevalence is high or in areas where intravenous drug use, high-risk sexual behaviours and penetrating trauma are more common. Patients with HIV may be expected to have higher rates of infectious and respiratory complications if they have active AIDS and/or liver disease caused by one of the hepatitis viruses. Certain aspects of therapy may change in this group of patients. Clinicians should be aware that highly active anti-retroviral therapy (HAART) might produce complications. Occupational exposure among healthcare workers is uncommon. Cases of infection in healthcare workers from needlesticks are rare. Certain precautions regarding body fluid and needlestick exposures have been widely adopted over the past decade. When percutaneous injury results in known exposure to HIV, post-exposure prophylaxis (PEP) should be used and can be expected to be effective in preventing infection in the large majority of cases.

Acute ovarian torsion is an uncommon cause of abdominal pain in female children and is often difficult to differentiate from other conditions causing lower abdominal pain. Acute adnexal pathology associated with appendicitis is very rare, with only a handful of reports available in the literature. Reported is a case of ovarian torsion associated with appendicitis in a 5-year-old girl along with a comprehensive literature review.

Deep venous thrombosis (DVT) and pulmonary embolism (PE) affect high-risk trauma patients (HRTP). Accurate incidence and clinical importance of DVT and PE in HRPT may be overstated. We performed a ten-year retrospective analysis of HRTP of the Pennsylvania Trauma Outcome Study. High-risk factors (HRF) included pelvic fracture (PFx), lower extremity fracture (LEFx), severe head injury (CHI) (AIS - head > or =3), and spinal cord injury. HRF alone or in combination, age, Injury Severity Score (ISS), and Glasgow Coma Score (GCS) were examined for association with DVT/PE. A total of 73,419 HRTP were included: 1377 (1.9%) had DVT, 365 (0.5%) had PE. The incidence of DVT in level I trauma centers was 2.2 per cent and was 1.5 per cent in level II centers. The lowest incidence of DVT was 1.3 per cent for isolated LEFx; highest was 5.4% for combined PFx, LEFx, and CHI. Variables associated with DVT included age, ISS, and GCS (all P < 0.001). In logistic regression analysis, only ISS was consistently predictive for DVT and PE. Though increased during the past decade, the overall incidence of DVT in HRTP remains below 3 per cent. Only the combination of multiple injuries or an ISS >30 result in DVT incidence of > or =5 per cent. We believe that current guidelines for screening for DVT may need to be reevaluated.
