ABSTRACT
BACKGROUND: Unlike large hemothoraces (HTX), small HTX after blunt trauma may be observed without drainage. We aimed to study if there were risk factors that would predict the need for intervention in initially observed small HTX. METHODS: A retrospective review of patients with blunt traumatic HTX from 2016 to 2022 was performed. Patients with small HTX (pleural fluid volume <400 mL on admission chest computerized tomography [CT]) were included. Patients were considered as being "initially observed" if there was no intervention for the HTX within 48 hours after admission. Primary outcome was any HTX-related intervention (open, thoracoscopic or percutaneous procedures) occurring after 48 hours and up to 6 months after injury. Univariable and multivariable statistical analyses were employed. A P-value of <.05 was considered significant. RESULTS: Of 335 patients with HTX, 188 (59.6%) met inclusion criteria. Median (interquartile range) HTX volume was 90 (36-134) ml. One hundred and twenty-seven (68%) were initially observed. Of these, 31 (24%) had the primary outcome. These patients had a larger HTX volume (median, 129 vs 68 mL, P = .0001), and number of rib fractures (median, 7 vs 4, P = .0002) compared to those without the primary outcome. Chest-related readmission occurred in 8 (6%) with a median of 20 days from injury. Of these, 7 required an HTX-related intervention. Logistic regression analysis found that both the number of rib fractures and HTX volume independently predicted the primary outcome. CONCLUSION: For small HTX initially observed, number of rib fractures and initial volume predicted delayed HTX-related intervention.

INTRODUCTION: Although low-energy pelvic fractures seldom present with significant hemorrhage, early recognition of at-risk patients is essential. We aimed to identify predictors of transfusion requirements in this cohort. METHODS: A 7-y retrospective chart review was performed. Low-energy mechanism was defined as falls of ≤5 feet. Fracture pattern was classified using the Orthopedic Trauma Association/Arbeitsgemeinschaft für Osteosynthesefragen system as A, B, or C. Primary outcome was transfusion of ≥2 units of packed red blood cells in the first 48 h. Univariable analysis and logistic regression analysis were performed. A P value ≤0.05 was considered significant. RESULTS: Five hundred forty six patients were included with median (interquartile range) age of 86 (79-91) and median (interquartile range) Injury Severity Score of 5 (4-8). Five hundred forty one (99%) had type A fractures. Twenty six (5%) had the primary outcome and 17 (3%) died. Logistic regression found that systolic blood pressure <100 mmHg at any time in the Emergency Department, Injury Severity Score, and pelvic angiography were predictors of the primary outcome. Seventeen percent of those who had the primary outcome died compared with 2% who did not (P = 0.0004). Three hundred sixty four (67%) received intravenous contrast for computerized tomography scans and of these, 44 (12%) had contrast extravasation (CE). CE was associated with the primary outcome but not mortality. CONCLUSIONS: Hypotension at any time in the Emergency Department and CE on computerized tomography predicted transfusion of ≥2 units packed red blood cells in the first 48 h in patients with low-energy pelvic fractures.

There is very little literature on the overall management of adolescent traumatic amputation, specifically of the lower extremity. We present a case involving an adolescent patient involved in an industrial farm tractor rollover with substantial crush and degloving injuries requiring bilateral lower extremity amputations. The patient was initially assessed and acutely managed in the field before arriving at an adult level 1 trauma center having two right lower extremity tourniquets already applied and a pelvic binder in place. During his hospitalization, he was revised to bilateral above-knee amputations that required multiple debridements prior to being transferred to a pediatric trauma center due to the extent of the soft tissue injury and need for flap coverage. Our adolescent patient presented with an uncommon injury mechanism resulting in significantly mangled lower extremities highlighting the importance of a multidisciplinary approach in all aspects of the patient's prehospital, intrahospital, and posthospital care.

INTRODUCTION: Neostigmine (NEO) and decompressive colonoscopy (COL) are two efficacious treatment modalities for acute colonic pseudo-obstruction (ACPO). We hypothesize that a COL first strategy is associated with better outcomes compared to a NEO first strategy. METHODS: A single-center retrospective analysis was performed from 2013 to 2020. Patients ≥18 y with a diagnosis of ACPO were included. The outcome was a composite measure of acute operative intervention, 30-day readmission with ACPO, and 30-day ACPO-related mortality. A P-value of ≤ 0.05 indicated statistical significance. RESULTS: Of 910 encounters in 849 patients, 50 (5.5%) episodes of ACPO in 39 patients were identified after exclusion of one patient with colon perforation on presentation. The median (interquartile range) age was 68 (62-84) y. NEO and COL were administered in 21 and 25 episodes, respectively. In 16 (32%) episodes, no NEO or COL was administered. When patients were given NEO first, COL or additional NEO was required in 12/18 (67%) compared with a COL first strategy where a second COL and/or NEO was given in 5/16 (32%) (P = 0.05). Both strategies had similar outcomes (NEO, 4/18 versus COL, 4/16, P = 0.85). Twenty-two (44%) episodes had an early intervention (≤48 h) with NEO and/or COL. There was no difference in outcome between those that received an early intervention and those who did not (5/22 versus 5/28, P = 0.71). CONCLUSIONS: For patients failing conservative measures, a COL first approach was associated with fewer subsequent interventions, but with similar composite outcomes compared to a NEO first approach. Early (≤48 h) intervention with NEO and/or COL was not associated with improved outcomes.

Pancreatic ischemia with necrosis is an extremely rare complication of splenic angioembolization (SAE). A 48-year-old male with a grade IV blunt splenic injury underwent angiography which demonstrated no active bleeding or pseudoaneurysm. Proximal SAE was performed. One week later, he developed severe sepsis. Repeat CT imaging showed nonperfusion of the distal pancreas, and laparotomy found necrosis of approximately 40% of the pancreas. Distal pancreatectomy and splenectomy were performed. He endured a prolonged hospital course with multiple complications. Clinicians should have a high index of suspicion for ischemic complications after SAE when sepsis develops.

Angioembolization in blunt splenic trauma is used to maximize splenic preservation. Superiority of prophylactic embolization over expectant management in patients with a negative splenic angiography (SA) is debated. We hypothesized that embolization in negative SA would be associated with splenic salvage. Of 83 patients undergoing SA, 30 (36%) had a negative SA. Embolization was performed in 23 (77%). Grade of injury, contrast extravasation (CE) on computed tomography (CT) or embolization were not associated with splenectomy. In 20 patients with either a high-grade injury or CE on CT, 17 (85%) underwent embolization with a failure rate of 24%. In the remaining 10 without high-risk features, 6 underwent embolization with a 0% splenectomy rate. Despite embolization, the failure rate of nonoperative management (NOM) remains significant in those with high-grade injury or CE on CT. A low threshold for early splenectomy after prophylactic embolization is needed.

INTRODUCTION: Blunt traumatic injuries are a leading cause of morbidity and mortality in the pediatric population. Contrast-enhanced multidetector computed tomography is the best imaging tool for screening patients at risk of blunt abdominal injury. The Pediatric Emergency Care Applied Research Network (PECARN) abdominal rule was derived to identify patients at low risk for significant abdominal injury who do not require imaging. METHODS: We conducted a retrospective review of pediatric patients with blunt trauma to validate the PECARN rule in a non-pediatric specialized hospital from February 3, 2013, through December 31, 2019. We excluded those with penetrating or mild isolated head injury. The PECARN decision rule was retrospectively applied for the presence of a therapeutic intervention, defined as a laparotomy, angiographic embolization, blood transfusion, or administration of intravenous fluids for pancreatic or gastrointestinal injury. Sensitivity and specificity analysis were conducted along with the negative and positive predictive values. RESULTS: A total of 794 patients were included in the final analysis; 23 patients met the primary outcome for an acute intervention. The PECARN clinical decision rule (CDR) had a sensitivity of 91.3%, a negative predictive value of 99.5, and a negative likelihood ration of 0.16. CONCLUSION: In a non-pediatric specialty hospital, the PECARN blunt abdominal CDR performed with comparable sensitivity and negative predictive value to the derivation and external validation study performed at specialized children's hospitals.
ABSTRACT
Data are lacking regarding the use of diuretics in facilitating closure of the open abdomen (OA). For patients with an OA after 2 laparotomies, we hypothesized that diuretic use was associated with a higher rate of primary fascial closure than no diuretic use. A retrospective review of patients with trauma laparotomies over 7 years was performed. Primary fascial closure (PFC) was defined as apposition of fascial edges without interposition mesh. Of 321 patients, 30 (9%) remained with an OA after 2 laparotomies. Prior to the third laparotomy, median cumulative fluid balance was +12.6 L. Thirteen (43%) received diuretics. Primary fascial closure rates were similar for diuretic use vs no diuretic (38% vs 59%, P = .46). Primary fascial closure was not associated with age (P = .2), gender (P = 0.7), cumulative fluid balance (P = .3), or units of packed cells (P = .4). Diuretic use in trauma patients with an OA after 2 laparotomies was not associated with successful PFC.

BACKGROUND: The significance of external signs (EST) and signs or symptoms of trauma (SS) after ground level falls or found down (GLF/FD) is unclear. We hypothesized that EST and SS were associated with injury. METHODS: Patients with GLF/FD were retrospectively studied. SS was defined as having any EST, tenderness, or subjective complaint. Outcomes were any significant finding (SF) and Injury Severity Score (ISS) > 8. Diagnostic accuracy of EST and SS were assessed with positive and negative likelihood ratios (LR+, LR-). RESULTS: Of 578 patients, 66% and 95% had EST and SS respectively. For EST, LR+ and LR-were 1.14 and 0.76 (SF), and 1.21 and 0.64 (ISS>8). For SS, LR+ and LR-were 1.07 and 0.19 (SF), and 1.03 and 0.49 (ISS>8). CONCLUSION: EST lacked sufficient diagnostic accuracy for SF and ISS>8. Lack of SS was reasonably accurate in ruling out SF but not ISS>8. Triage utilizing EST alone for GLF/FD is not useful.

BACKGROUND: The natural history of traumatic hemothorax (HTX) remains unclear. We aimed to describe outcomes of HTX following tube thoracostomy drainage and to delineate factors that predict progression to a retained hemothorax (RH). We hypothesized that initial large-volume HTX predicts the development of an RH. METHODS: We conducted a prospective, observational, multi-institutional study of adult trauma patients diagnosed with an HTX identified on computed tomography (CT) scan with volumes calculated at time of diagnosis. All patients were managed with tube thoracostomy drainage within 24 hours of presentation. Retained hemothorax was defined as blood-density fluid identified on follow-up CT scan or need for additional intervention after initial tube thoracostomy placement for HTX. RESULTS: A total of 369 patients who presented with an HTX initially managed with tube thoracostomy drainage were enrolled from 17 trauma centers. Retained hemothorax was identified in 106 patients (28.7%). Patients with RH had a larger median (interquartile range) HTX volume on initial CT compared with no RH (191 [48-431] mL vs. 88 [35-245] mL, p = 0.013) and were more likely to be older with a higher burden of thoracic injury. After controlling for significant differences between groups, RH was independently associated with a larger HTX on presentation, with a 15% increase in risk of RH for each additional 100 mL of HTX on initial CT imaging (odds ratio, 1.15; 95% confidence interval, 1.08-1.21; p < 0.001). Patients with an RH also had higher rates of pneumonia and longer hospital length of stay than those with successful initial management. Retained hemothorax was also associated with worse functional outcomes at discharge and first outpatient follow-up. CONCLUSION: Larger initial HTX volumes are independently associated with RH, and unsuccessful initial management with tube thoracostomy is associated with worse patient outcomes. Future studies should use this experience to assess a range of options for reducing the risk of unsuccessful initial management. LEVEL OF EVIDENCE: Therapeutic/care management study, level III.

BACKGROUND: We sought to determine if clinician suspicion of injury was useful in predicting injuries found on pan-body computed tomography (PBCT) in clinically intoxicated patients. METHODS: We prospectively enrolled awake, intoxicated patients with low-energy mechanism of injury. For each of four body regions (head/face, neck, thorax and abdomen/pelvis), clinician suspicion for injury was recorded as "low index" or "more than a low index". The reference standard was the presence of any pre-defined significant finding (SF) on CT. Sensitivity, specificity, positive (LR+) and negative (LR-) likelihood ratios were calculated. RESULTS: Enrollment of 103 patients was completed. Sensitivity, specificity, LR+ and LR-for clinician index of suspicion were: 56%, 68%, 1.75, 0.64 (head/face), 50%, 92%, 6.18, 0.54 (neck), 10%, 96%, 2.60, 0.94 (thorax) and 67%, 93%, 9.56, 0.36 (abdomen/pelvis). CONCLUSION: Clinician judgement was most useful to guide need for CT imaging in the neck and abdomen/pelvis. Routine PBCT may not be necessary. SUMMARY: For awake, stable intoxicated patients after falls and assaults, clinician index of suspicion was most useful to guide the need for CT imaging in the neck and abdomen/pelvis. Our findings support selective use of CT if the index of suspicion is low. Routine PBCT may not be necessary.

BACKGROUND: In the nonoperative management (NOM) of blunt splenic injuries (BSI), the clinical relevance of age as a risk factor has not been well studied. METHODS: Using the 2011 National Trauma Data Bank data set, age was analyzed both as a continuous variable and a categorical variable (group 1 [13-54 y], group 2 [55-74 y], and group 3 [≥75 y]). BSI severity was stratified by abbreviated injury scale (AIS): group 1 (AIS ≤2), group 2 (AIS 3), and group 3 (AIS ≥4). A semiparametric proportional odds model was used to model NOM outcomes and effects due to age and BSI severity. RESULTS: Of 15,113 subjects, 15.3% failed NOM. The odds of failure increased by a factor of 1.014 for each year of age, or factor of 1.5 for groups 2 and 3 each. BSI severity groups 2 and 3 had increases in the odds of failure by factors of 3.9 and 13, respectively, compared with those of group 1. Most failures occurred by 48 h irrespective of age. The effect of age was most pronounced in age groups 2 and 3 with the most severe BSI, where a NOM failure rate of >50% was seen. Both age and failure of NOM were independent predictors of mortality. CONCLUSIONS: Age is associated with failure of NOM but its effect seems more clinically relevant only in high-grade BSI. Factors that could influence NOM success in elderly patients with high-grade injuries deserve further study.
