Abstract: Background: The purpose of this study is to characterize traumatic suicide attempts (TSA) by age, gender, race, and mechanism of injury. Methods: This is a retrospective review of TSA patients (identified by E-codes) admitted to our urban, level I trauma center from 1992 through 2005. Mechanisms of TSA included jump from height, firearm (gunshot wound [GSW]), cutting or piercing instrument (stab wound [SW]), and motor vehicle (MV)-related. Patients were categorized in groups by age in years (< 18, 18–35, 36–54, 55–69, ≥ 70). Results: A total of 876 TSA patients were identified; 83% were male, with a mean age of 35 years and a mean Injury Severity Score of 10. The most common mechanism was SW (39%), followed by jump (26%), GSW (21%), and MV-related (13%). Primary mechanism of TSA varied by age (p < 0.0001), with GSW most common in those patients aged < 18 years (64%) and ≥ 70 years (44%), and SW most common in all other age groups. Overall, 16% of TSAs were successful. The adjusted odds ratio (AOR) for mortality for age 70+ vs. age 36–54 was 12.4 (95% confidence interval [CI] 2.3–78, p = 0.005), and the AOR for mortality from GSW vs. SW was 9.8 (95% CI 2.6–44, p = 0.001). Conclusions: The most common mechanism for TSA was SW, although GSW was the most effective. The mechanism of choice for TSA depends on age, with the extremes of age more commonly choosing a firearm. Age and method of TSA are significant contributing factors to success of suicide attempts. [ABSTRACT FROM AUTHOR]

Agitation on arrival in trauma patients is known as a sign of impending demise. The aim of this study is to determine outcomes for trauma patients who present in an agitated state. We hypothesized that agitation in the trauma bay is an early indicator for hemorrhage in trauma patients. We performed a single-institution prospective observational study from September 2018 to December 2020 that included any trauma patient who arrived agitated, defined as a Richmond Agitation-Sedation Scale of +1 to +4. Variables collected included demographics, mechanism of injury, admission physiology, blood alcohol level, toxicity screen, and injury severity. The primary outcomes were need for massive transfusion (≥ 10 units) and need for emergent therapeutic intervention for hemorrhage control (laparotomy, preperitoneal pelvic packing, sternotomy, thoracotomy, or angioembolization). Of 4657 trauma admissions, 77 (2%) patients arrived agitated. Agitated patients were younger (40 versus 46, P = 0.03), predominantly male (94% versus 66%, P < 0.0001) sustained more penetrating trauma (31% versus 12%, P < 0.0001), had a lower systolic blood pressure (127 versus 137, P < 0.0001), and a higher Injury Severity Score (17 versus 9, P < 0.0001). On multivariable logistic regression, agitation was independently associated with massive transfusion (odds ratio: 2.63 [1.20-5.77], P = 0.02) and emergent therapeutic intervention for hemorrhage control (odds ratio: 2.60 [1.35-5.03], P = 0.005). Agitation in trauma patients may serve as an early indicator of hemorrhagic shock, as agitation is independently associated with a two-fold increase in the need for massive transfusion and emergent therapeutic intervention for hemorrhage control.

INTENSIVE care units , *TRAUMA centers , *HOSPITAL mortality - Abstract
Failed extubation in critically ill patients is associated with poor outcomes. In critically ill trauma patients who have failed extubation, providers must decide whether to proceed with tracheostomy or attempt extubation again. The aim of this study was to describe the natural history of failed extubation in trauma patients and determine whether tracheostomy or a second attempt at extubation is more appropriate. Trauma patients admitted to our level I trauma center from 2013 to 2019 were identified. Patients who failed extubation, defined as an unplanned reintubation within 48 h of extubation, were included. Patients who immediately underwent tracheostomy were compared with those who had subsequent attempts at extubation. The primary outcome was mortality, and the secondary outcomes were intensive care unit (ICU) length of stay (LOS), ventilator days, and hospital LOS. The population included 93 patients who failed extubation and met inclusion criteria. A total of 53 patients were ultimately successfully extubated, whereas 40 patients underwent a tracheostomy. There was no statistically significant difference in demographics or injury patterns. Patients who underwent tracheostomy had a longer ICU LOS and more ventilator days. There was no difference in mortality or hospital LOS between the two groups. In trauma patients, those who underwent subsequent attempts at extubation did not experience higher rates of mortality than those who received a tracheostomy. Tracheostomy was associated with longer ICU LOS and ventilator days. In certain situations, it is appropriate to consider subsequent attempts at extubation in trauma patients who fail extubation rather than proceeding directly to tracheostomy. [ABSTRACT FROM AUTHOR]

Summary: Purpose: To evaluate the prevalence of the acute respiratory distress syndrome (ARDS) among blunt trauma patients with severe traumatic brain injury (TBI) and to determine if ARDS is associated with higher mortality, morbidity and worse discharge outcome. Methods: Blunt trauma patients with TBI (head abbreviated injury score {AIS}≥4) who developed predefined ARDS criteria between January 2000 and December 2004 were prospectively collected as part of an ongoing ARDS database. Each patient in the TBI+ARDS group was matched with two control TBI patients based on age, injury severity score (ISS) and head AIS. Outcomes including complications, mortality and discharge disability were compared between the two groups. Results: Among 362 TBI patients, 28 (7.7%) developed ARDS. There were no differences between the two groups with respect to age, sex, ISS, Glasgow coma score (GCS), head, abdomen and extremity AIS. The TBI+ARDS group had significantly more patients with chest AIS≥3 (57.1% versus 32.1%, p =0.03). There was no difference with respect to overall mortality between the TBI+ARDS group (50.0%) and the TBI group (51.8%) (OR 0.79: 95% CI 0.31–2.03, p =0.63). There was no significant difference with respect to discharge functional capacity between the two groups. There were significantly more overall complications in the TBI+ARDS group (42.9%) compared to the TBI group (16.1%) (OR 3.66: 95% CI 1.19–11.24, p =0.02). The TBI+ARDS group had an overall mean intensive care unit (ICU) length of stay of 15.6 days, versus 8.4 days in the TBI group (p <0.01). The TBI+ARDS group had significantly higher hospital charges than the TBI group ($210,097 versus $115,342, p <0.01). Conclusion: The presence of ARDS was not associated with higher mortality or worse discharge disability. It was, however, associated with higher hospital morbidity, longer ICU and hospital length of stay. [Copyright &y& Elsevier]

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.

Angioembolization (AE) is an adjunct to nonoperative management (NOM) of splenic injuries. We hypothesize that failure of AE is associated with blood transfusion, grade of injury, and technique of AE. We performed a retrospective (2010-2017) multicenter study (nine Level I trauma centers) of adult trauma patients with splenic injuries who underwent splenic AE. Variables included patient physiology, injury grade, transfusion requirement, and embolization technique. The primary outcome was NOM failure requiring splenectomy. Secondary outcomes were mortality, complications, and length of stay. A total of 409 patients met inclusion criteria; only 33 patients (8%) required delayed splenectomy. Patients who failed received more blood in the first 24 h (P = 0.009) and more often received massive transfusion (P = 0.01). There was no difference in failure rates for grade of injury, contrast blush on computed tomography, and branch embolized. After logistic regression, transfusion in the first 24 h was independently associated with failure of NOM (P = 0.02). Patients who failed NOM had more complications (P = 0.002) and spent more days in the intensive care unit (P < 0.0001), on the ventilator (P = 0.0001), and in the hospital (P < 0.0001). Patients who failed NOM had a higher mortality (15% versus 3%, P = 0.007), and delayed splenectomy was independently associated with mortality (odds ratio, 4.2; 95% confidence interval, 1.2-14.7; P = 0.03). AE for splenic injury leads to effective NOM in 92% of patients. Transfusion in the first 24 h is independently associated with failure of NOM. Patients who required a delayed splenectomy suffered more complications and had higher hospital length of stay. Failure of NOM is independently associated with a fourfold increase in mortality. • Splenic angioembolization in trauma is safe. • There is no difference in embolization failure rates for grade of splenic injury. • There is no difference in failure rate for patients with a contrast blush on CT. • Transfusion in the first 24 h is associated with splenic embolization failure. • Failure of splenic embolization is associated with five-fold increase in mortality.

Abstract: Introduction: Retained haemothorax (RH) is a problematic sequela of thoracic trauma, reported in up to 20% of patients following chest injury. RH is associated with a higher severity of thoracic trauma and may portend the onset of other serious post-traumatic complications, including pneumonia. The development of pneumonia has previously been reported to be as high as 19.5% in the setting of traumatic RH. The purpose of this study was to identify risk factors for the development of pneumonia as a complication in RH. Methods: We utilized the American Association for the Surgery of Trauma Post-Traumatic Retained Haemothorax database. Patients with post-traumatic RH were prospectively enrolled from 2009 to 2011. Inclusion criteria were placement of a thoracostomy tube within 24h of admission for the evacuation of pneumothorax or haemothorax and subsequent chest computed tomography scan chest showing RH. Patients treated with thoracotomy before placement of tube thoracostomy were excluded. For univariate analysis, the Chi-square test with Yates correction was used for comparison of categorical risk factors and the Student's t-test or the Mann–Whitney test for comparison of continuous risk factors. To identify independent risk factors for the development of pneumonia, variables from the univariate analysis significant at p <0.2 were entered into a forward logistic regression model. Adjusted odds ratio and 95% confidence intervals (CI) were derived. Results: 328 patients with post-traumatic RH from 20 United States centres were enrolled. After stepwise regression analysis, ISS>25 (adjusted OR: 7.1; 95% CI: 3.1, 16.4; p <0.001), blunt mechanism of injury (adjusted OR: 3.5; 95% CI: 1.7, 7.2; p =0.001), and failure to administer peri-procedural antibiotics on the initial thoracostomy tube placement (adjusted OR: 2.6; 95% CI: 1.30, 5.4; p =0.01) were found to be independent predictors of the pneumonia in patients with post-traumatic RH. Conclusions: To our knowledge, our current study is the largest attempt to identify the independent predictors for pneumonia in this population. Our data show that elevated ISS, blunt thoracic trauma, and failure to administer peri-procedural antibiotics on tube thoracostomy placement are the statistically significant independent risk factors.

Abstract: Purpose: Both lactate and base deficit (BD) are used as predictors of injury severity and mortality. We examined the significance of these measures when used in combination, and particularly when they provide conflicting data. Methods: We reviewed all intensive care unit patients with simultaneously obtained lactate and BD measurements. The ability to predict mortality and hospital stay was compared alone, in combination, and when there was disagreement between the measures. Receiver operating characteristic curves were generated to compare predictive abilities. Results: There were 1,298 patients with 12,197 sets of paired laboratory data; 1,026 trauma patients and 272 surgical patients. Lactic acidosis was present in 41% and a significant BD level (>2) was found in 52%. Nonsurvivors had higher admission lactate (6.2 vs. 3.3) and base deficit (6.1 vs. 3.2) levels than survivors (both P < .01), with a modest correlation (r = .52) between the measures. The admission lactate and BD levels had similar predictive ability for mortality, with areas under the receiver operating characteristic curve of .7 and .66, respectively (both P < .01). However, the predictive ability of the BD level decreased significantly during the intensive care unit stay (area, .5) compared with lactate level (area, .68). Lactate and BD levels disagreed in 44% of all laboratory sets. In patients with a normal lactate level (<2.2), the BD level had no predictive ability for mortality (area, .48; P = .26). However, in patients with a normal BD level (<2.0), the lactate level retained its predictive ability for mortality (area, .67; P < .01). Lengths of stay were longer among patients with an increased lactate level, even when the BD level was normal. There was no improvement in predictive ability using a combination of the 2 measures. Conclusions: Both lactate and BD levels may be used to identify lactic acidosis and predict mortality at admission. Increased lactate levels predict mortality and a prolonged course regardless of the associated BD level, whereas an increased BD level has no predictive value if the lactate level is normal.
