Degloving soft tissue injuries (DSTIs) are serious surgical conditions. We aimed to evaluate the pattern, management and outcome of DSTIs in a single institute. A retrospective analysis was performed for patients admitted with DSTIs from 2011to 2013. Presentation, management and outcomes were analyzed according to the type of DSTI. Of 178 DSTI patients, 91 % were males with a mean age of 30.5 ± 12.8. Three-quarter of cases was due to traffic–related injuries. Eighty percent of open DSTI cases were identified. Primary debridement and closure (62.9 %) was the frequent intervention used. Intermediate closed drainage under ultrasound guidance was performed in 7 patients; however, recurrence occurred in 4 patients who underwent closed serial drainage for recollection and ended with a proper debridement with or without vacuum assisted closure (VAC). Closed DSTIs were mainly seen in the lower extremity and back region and initially treated with conservative management as compared to open DSTIs. Infection and skin necrosis were reported in 9 cases only. Open DSTIs were more likely involving head and neck region and being treated by primary debridement/suturing and serial debridement/washout with or without VAC. All-cause DSTI mortality was 9 % that was higher in the closed DSTIs (19.4 vs 6.3 %; p = 0.01). The incidence of DSTIs is 4 % among trauma admissions over 3 years, with a greater predilection to males and young population. DSTIs are mostly underestimated particularly in the closed type that are usually missed at the initial presentation and associated with poor outcomes. Treatment guidelines are not well established and therefore further studies are warranted.

Blunt trauma patients with rib fractures were studied to determine whether the number of rib fractures or their patterns were more predictive of abdominal solid organ injury and/or other thoracic trauma. Rib fractures were characterized as upper zone (ribs 1 to 4), midzone (ribs 5 to 8), and lower zone (ribs 9 to 12). Findings of sternal and scapular fractures, pulmonary contusions, and solid organ injures (liver, spleen, kidney) were characterized by the total number and predominant zone of ribs fractured. There were 296 men and 14 women. There were 38 patients with scapular fracture and 19 patients with sternal fractures. There were 90 patients with 116 solid organ injuries: liver (n = 42), kidney (n = 27), and spleen (n = 47). Lower rib fractures, whether zone-limited or overlapping, were highly predictive of solid organ injury when compared with upper and midzones. Scapular and sternal fractures were more common with upper zone fractures and pulmonary contusions increased with the number of fractured ribs. Multiple rib fractures involving the lower ribs have a high association with solid organ injury, 51 per cent in this series. The increasing number of rib fractures enhanced the likelihood of other chest wall and pulmonary injuries but did not affect the incidence of solid organ injury.

Introduction: This is a structured scoping review to assess whether there is a relationship between stress-induced hyperglycemia (SIH), cytokine interactions, and mortality in trauma patients in comparison to non-diabetic normoglycemia [NDN], diabetic normoglycemia [DN], and diabetic hyperglycemia [DH]. Methods: We conducted a literature search of MEDLINE (PubMed) databases from 2000 to 2022 using a search strategy to identify observational studies. Initially, 2879 articles were retrieved. Of these, 2869 were excluded due to insufficient variables, and non-trauma focuses. Results: Nine studies on the interaction between SIH and proinflammatory cytokines were analyzed. SIH was associated with the highest mortality rate (21.3%), followed by DH (5.4%), DN (2.8%), and NDN (2.3%) (p < 0.001). Furthermore, SIH patients exhibited an 11.28-fold higher likelihood of mortality compared to NDN patients (95% CI [9.13–13.93]; p < 0.001) and a 4.72-fold higher likelihood compared to DH patients (OR 4.72; 95% CI [3.55–6.27]; p < 0.001). Conclusions: SIH patients had elevated IL-6 concentrations relative to NDN, DN, and DH patients. SIH is linked to higher mortality in trauma, with greater odds than NDN. However, the robustness of this association is still being determined due to statistical and clinical variability. Uncertainties about injury severity and IL-6 level similarities between SIH and DH patients require further investigation.

Background: We aimed to study the presentation, management, and outcomes of patients with a pancreatic traumatic injury. Methods: We retrospectively analyzed data for all patients who were admitted with pancreatic injuries between 2011 and 2017 at the only level 1 trauma center in the country. Results: There were 71 patients admitted with pancreatic trauma (0.6% of trauma admissions and 3.4% of abdominal injury admissions) with a mean age of 31 years. Sixty-two patients had pancreatic injury grade I–II and nine had injury grade III–IV. Thirty-eight percent had Glasgow Coma Scale (GCS) 16. The level of pancreatic enzymes was significantly proportional to the grade of injury. Over half of patients required laparotomy, of them 12 patients had an intervention on the pancreas. Eight patients developed complications related to pancreatic injuries ranging from pancreatitis to pancreatico-cutaneous fistula while 35% developed hemorrhagic shock. Mortality was 31% and regardless of the grade of injury, the mortality was associated with high ISS, low GCS, and presence of hemorrhagic shock. Conclusion: Pancreatic injuries following blunt trauma are rare, and the injured subjects are usually young men. However, most injuries are of low-grade severity. This study shows that regardless of the pancreatic injury grade on-admission shock, higher ISS and lower GCS are associated with worse in-hospital outcomes. Non-operative management (NOM) may suffice in patients with lower grade injuries, which may not be the case in patients with higher grade injuries unless carefully selected.

We aimed to evaluate the outcomes of post-traumatic acute respiratory distress syndrome (ARDS) in young patients with and without Extracorporeal membrane oxygenation (ECMO) support. A retrospective analysis was conducted for trauma patients who developed ARDS at a level I trauma facility between 2014 and 2020. Data were analyzed and compared between ECMO and non-ECMO group. We identified 85 patients with ARDS (22 patients had ECMO support and 63 matched patients managed by the conventional mechanical ventilation; 1:3 matching ratio). The two groups were comparable for age, sex, injury severity score, abbreviated injury score, shock index, SOFA score, and head injury. Kaplan Meier survival analysis showed that the survival in the ECMO group was initially close to that of the non-ECMO, however, during follow-up, the survival rate was better in the ECMO group, but did not reach statistical significance (Log-rank, p = 0.43 and Tarone-Ware, p = 0.37). Multivariable logistic regression analysis showed that acute kidney injury (AKI) (Odds ratio 13.03; 95% CI 3.17–53.54) and brain edema (Odds ratio 4.80; 95% CI 1.10–21.03) were independent predictors of mortality. Sub-analysis showed that in patients with severe Murray Lung Injury (MLI) scores, non-ECMO group had higher mortality than the ECMO group (100% vs 36.8%, p = 0.004). Although ARDS is uncommon in young trauma patients, it has a high mortality. ECMO therapy was used in a quarter of ARDS cases. AKI and brain edema were the predictors of mortality among ARDS patients. ECMO use did not worsen the outcome in trauma patients; however, the survival was better in those who had severe MLI and ECMO support. Further prospective study is needed to define the appropriate selection criteria for the use of ECMO to optimize the outcomes in trauma patients.
