RESUMEN
BACKGROUND: This study evaluates the utility of chest (CXR) and pelvis (PXR) X-ray, as adjuncts to the primary survey, in screening geriatric blunt trauma (GBT) patients for abdominal injury or need for laparotomy. METHODS: We performed a retrospective analysis of patients 65-89 years in the 2014 National Trauma Data Bank. X-ray injuries were identified by ICD9 codes and defined as any injury felt to be readily detectable by a non-radiologist. X-ray findings were dichotomized as "both negative" (no injury presumptively apparent on CXR or PXR) or "either positive" (any injury presumptively apparent on CXR or PXR). Rates of abdominal injuries and laparotomy were compared and used to calculate sensitivity and specificity. The primary outcomes were abdominal injury and laparotomy. The secondary outcomes included mortality, ventilator days, and hospital days. RESULTS: A total of 202 553 patients met criteria. Overall, 9% of patients with either positive X-rays had abdominal injury and 2% laparotomy vs. 1.1% and .3% with both negative (P < .001). The specificity for any positive X-ray was 79% for abdominal injury and 78% for laparotomy. The sensitivity was 69% for abdominal injury and laparotomy. The either positive group had fewer ventilator days (.3 vs. .8, P < .0001), longer length of stay (7 vs. 5, P < .0001), and higher mortality (6% vs. 4%, P < .0001) vs both negative. CONCLUSION: CXR and PXR can be used to assess for intra-abdominal injury and need for laparotomy. GBT patients with either positive X-rays should continue workup regardless of mechanism due to the high specificity of this tool for abdominal injury and need for laparotomy.

INTRODUCTION: Large animal-related injuries (LARI) are relatively uncommon, but, nevertheless, a public hazard. The objective of this study was to better understand LARI injury patterns and outcomes. MATERIALS AND METHODS: We performed a retrospective review of the 2016 National Trauma Data Bank and used ICD-10 codes to identify patients injured by a large animal. The primary outcome was severe injury pattern, while secondary outcomes included mortality, hospital length of stay, ICU admission, and mechanical ventilation usage. RESULTS: There were 6,662 LARI included in our analysis. Most LARI (66%) occurred while riding the animal, and the most common type of LARI was fall from horse (63%). The median ISS was 9 and the most severe injuries (AIS ≥ 3) were to the chest (19%), head (10%), and lower extremities (10%). The overall mortality was low at 0.8%. Compared to non-riders, riders sustained more severe injuries to the chest (21% vs. 16%, p<0.001) and spine (4% vs. 2%, p<0.001). Compared to motor vehicle collisions (MVC), riders sustained fewer severe injuries to the head (10% vs. 12%, p<0.001) and lower extremity (10% vs. 12%, p=0.01). Compared to auto-pedestrian accidents, non-riders sustained fewer severe injuries to the head (11% vs. 19%, p<0.001) and lower extremity (10% vs. 20%, p<0.001). CONCLUSION: Patients involved in a LARI are moderately injured with more complex injuries occurring in the chest, head, and lower extremities. Fall from horse was the most common LARI mechanism. Overall mortality was low. Compared to non-riders, riders were more likely to sustain severe injuries to the chest and spine. Severe injury patterns were similar when comparing riders to MVC and, given that most LARI are riding injuries, we recommend trauma teams approach LARI as they would an MVC.

BACKGROUND: Several options exist for induction agents during rapid sequence intubation (RSI) in trauma patients, including etomidate, ketamine, and propofol. These drugs have reported variable hemodynamic effects (hypotension with propofol and sympathomimetic effects with ketamine) that could affect trauma resuscitations. The purpose of this study was to compare the hemodynamic effects of these three induction agents during emergency department RSI in adult trauma. We hypothesized that these drugs would display a differing hemodynamic profile during RSI. METHODS: We performed a retrospective (2014-2019), multicenter trial of adult (≥18 years) trauma patients admitted to eight ACS-verified Level I trauma centers who underwent emergency department RSI. Variables collected included systolic blood pressure (SBP) and pulse before and after RSI. The primary outcomes were change in heart rate and SBP before and after RSI. RESULTS: There were 2,092 patients who met criteria, 85% received etomidate (E), 8% ketamine (K), and 7% propofol (P). Before RSI, the ketamine group had a lower SBP (E, 135 vs. K, 125 vs. P, 135 mm Hg, p = 0.04) but there was no difference in pulse (E, 104 vs. K, 107 vs. P, 105 bpm, p = 0.45). After RSI, there were no differences in SBP (E, 135 vs. K, 130 vs. P, 133 mm Hg, p = 0.34) or pulse (E, 106 vs. K, 110 vs. P, 104 bpm, p = 0.08). There was no difference in the average change of SBP (E, 0.2 vs. K, 5.2 vs. P, -1.8 mm Hg, p = 0.4) or pulse (E, 1.7 vs. K, 3.5 bpm vs. P, -0.96, p = 0.24) during RSI. CONCLUSION: Contrary to our hypothesis, there was no difference in the hemodynamic effect for etomidate versus ketamine versus propofol during RSI in trauma patients. LEVEL OF EVIDENCE: Therapeutic, Level IV.

BACKGROUND: We aimed to identify risk factors and risk scoring models to help identify post-traumatic pulmonary embolisms (PE). METHODS: We performed a retrospective review (2014-2019) of all adult trauma patients admitted to our Level I trauma center that received a CT pulmonary angiogram (CTPA) for a suspected PE. A systematic literature search found eleven risk scoring models, all of which were applied to these patients. Scores of patients with and without PE were compared. RESULTS: Of the 235 trauma patients that received CTPA, 31 (13%) showed a PE. No risk scoring model had both a sensitivity and specificity above 90%. The Wells Score had the highest area under the curve (0.65). After logistic regression, no risk scoring model variables were independently associated with PE. CONCLUSIONS: In trauma patients with clinically suspected PE, clinical variables and current risk scoring models do not adequately differentiate patients with and without PE.

BACKGROUND: Whether magnetic resonance imaging (MRI) adds value to surgical planning for patients with acute traumatic cervical spinal cord injury (ATCSCI) remains controversial. In this study, we compared surgeons' operative planning decisions with and without preoperative MRI. We had two hypotheses: (1) the surgical plan for ATCSCI would not change substantially after the MRI and (2) intersurgeon agreement on the surgical plan would also not change substantially after the MRI. METHODS: We performed a vignette-based survey study that included a retrospective review of all adult trauma patients who presented to our American College of Surgeons-verified level 1 trauma center from 2010 to 2019 with signs of acute quadriplegia and underwent computed tomography (CT), MRI, and subsequent cervical spine surgery within 48 hours of admission. We abstracted patient demographics, admission physiology, and injury details. Patient clinical scenarios were presented to three spine surgeons, first with only the CT and then, a minimum of 2 weeks later, with both the CT and MRI. At each presentation, the surgeons identified their surgical plan, which included timing (none, <8, <24, >24 hours), approach (anterior, posterior, circumferential), and targeted vertebral levels. The outcomes were change in surgical plan and intersurgeon agreement. We used Fleiss' kappa (κ) to measure intersurgeon agreement. RESULTS: Twenty-nine patients met the criteria and were included. Ninety-three percent of the surgical plans were changed after the MRI. Intersurgeon agreement was "slight" to "fair" both before the MRI (timing, κ = 0.22; approach, κ = 0.35; levels, κ = 0.13) and after the MRI (timing, κ = 0.06; approach, κ = 0.27; levels, κ = 0.10). CONCLUSION: Surgical plans for ATCSCI changed substantially when the MRI was presented in addition to the CT; however, intersurgeon agreement regarding the surgical plan was low and not improved by the addition of the MRI. LEVEL OF EVIDENCE: Diagnostic, level II.

AIM: The number of geriatric trauma patients is rising; yet, there is no established best team to care for them. This study analyzed a geriatric trauma service (GTS) that is integrated into the trauma surgery workflow rather than a separate consultation service. We hypothesize this team will lead to decreased mortality, shorter length of stay and increased favorable discharges for geriatric trauma patients. METHODS: In July 2017, we established a GTS consisting of geriatric nurse practitioners who were part of the hospital's geriatrics service, trauma surgeons and surgery residents on the acute care surgery service. The geriatric nurse practitioners were integrated into the trauma surgery workflow and functioned as independent members. The GTS responded to traumas and consultations for patients aged ≥65 years. Trauma surgeons carried out intensive care and operative management, while the geriatric nurse practitioners managed medical issues, family communication and end-of-life planning. We carried out a 2 year retrospective analysis of trauma patients aged ≥65 years seen at Dell Seton Medical Center at the University of Texas, Austin, Texas, USA, comparing patient outcomes before and after the GTS. The primary outcome was mortality, whereas secondary outcomes included hospital days, intensive care unit days, and discharge disposition. RESULTS: We found no difference in mortality, intensive care unit days or hospital days with the GTS. However, post-GTS patients were more often discharged to home, rehabilitation, or hospice, and less often to nursing homes. CONCLUSION: An integrated geriatric and trauma team is feasible, and significant changes in disposition can be made by utilizing geriatric nurse practitioners. Geriatr Gerontol Int 2020; 20: 817-821.
