A decade of managing pediatric major traumatic vascular injuries: insights from a referral center

Abstract Purpose Incidence, management, and outcomes of pediatric vascular injuries secondary to non-iatrogenic trauma were reviewed over a decade in our institution. Methods A retrospective review of medical records (2013–2022) of major traumatic vascular injuries, focusing on injury profiles, treatment modalities, and clinical outcomes. Results Thirty patients with 48 vessel injuries were included. Firearms were the leading mechanism, accounting for 43.3% (n = 13) of cases. We identified 29 arterial injuries and 19 venous injuries, with 30 (62.5%) of the overall injuries occurred in the lower extremities. Shock (17; 56.7%) and associated injuries (25; 83.3%) were common. Surgery was the most common management strategy. Autologous bypass graft was the most frequently performed procedure for arterial injuries (8; 42.1%), while ligation dominated in venous injuries (9; 64.3%). Blood transfusion requirements (24; 82.7%) and post-operative prescription of anticoagulant and antiplatelet agents (12; 41.4%) were similar for arterial and venous injuries (p > 0.05). Three patients demised, resulting in a 90% survival rate. Neither the mechanism of injury, anatomical location, and presence of shock on arrival nor the baseline hemoglobin level served as predictors of mortality. Conclusion Intensive resuscitation with blood transfusion and prompt surgical intervention achieve favorable survival rates for pediatric traumatic vascular injuries. Optimal post-operative anticoagulant and antiplatelet regimens remain unclear.

Abstract Su601: Missed Hypoxia in the Prehospital Care of Major Traumatic Brain Injury: Discrepancies Between Continuous Monitor Data and Clinical Documentation

Background: It is well established that prehospital hypoxia dramatically increases mortality in Traumatic Brain Injury (TBI). Thus, in EMS TBI research, case ascertainment and risk adjustment are highly dependent upon documentation of in-field O 2 saturation (SpO 2 ). Objective: To compare the rate of hypoxia identified by EMS personnel and documented in EMS patient care records (PCR) versus the actual rate of hypoxia recorded by continuous, non-invasive monitoring in TBI. Methods: A subset of major TBI cases (moderate/severe) from 5 EMS agencies reporting monitor data (Philips MRx™) in the EPIC EMS TBI Study (NIH 1R01NS071049) were evaluated (02/13-02/18). All monitor data available for post-hoc review were displayed and accessible to the providers during EMS care. We compared PCR documentation of hypoxia (SpO 2 <90%) to continuous monitor data in TBI patients (nasal canula O 2 , mask, basic or advanced airway). Statistic: exact McNemar’s test, α=0.05. Results: 120 cases were included [med. age 50; IQR (23.8, 68); 65% male. Monitors recorded 44 hypoxic cases (36.7%; 95%CI 28.1, 45.9%). Only 8 (6.7%; 2.9, 12.7%) were documented in the PCR (p<0.0001; Figure). Three machine-detected hypoxia cases had no PCR-documented SpO 2 at all. Conclusions: The difference in PCR-documented and monitor-identified hypoxia was dramatic. The monitor data revealed a five-fold greater incidence of hypoxia than that documented by EMS providers. This may be partially explained by the continuous nature of pulse oximetry in the face of ongoing care responsibilities and scene distractions. The field environment may cause providers to miss low readings as they fluctuate moment-by-moment. These findings have major clinical implications. While some of the discrepancy between PCR reporting and monitor data might simply be failure to document hypoxia, the much more concerning implication is that many cases might be unrecognized and untreated. Furthermore, these findings have important implications for case ascertainment, confounding, and risk-adjustment in EMS TBI research. Whenever possible, quality improvement and research projects should utilize continuous non-invasive monitor data to identify and evaluate hypoxic patients in the setting of TBI. These findings may also have implications for identifying hypoxia in EMS patients with other critical conditions.

Trauma Connect Clinic: Continuing the trauma case management model for patients affected by traumatic injuries: A quality improvement initiative

Background: A case-management model of care is frequently used in acute-care settings for patients with major traumatic injuries; however, its application to trauma follow-up care after hospital discharge remains unclear. Aim: To describe the services provided by the Trauma Connect Clinic (TCC): a NP- led case management model, in trauma follow-up care. Methods: An exploratory descriptive study design was used. Data collected included patient and injury characteristics, clinic activities, attendance rates, referral patterns and complications. Results: Three-hundred and twenty-four TCC appointments were scheduled for 194 patients (n = 302) with an attendance rate of 93% (n = 302). Ongoing health issues included pain (n = 22, 37%), thrombotic events (n = 8, 13%) and infection (n = 7, 12%). Clinic activity included 77 referrals to the wider MDT (n = 77), radiology reviews (n = 225) and 39 prescribing events, consisting mainly of analgesia. Conclusion: A case management model can successfully deliver trauma follow-up care and efficiently use limited resources. Key elements involve careful assessment and management of patients’ physical and emotional needs. Evaluation of longer-term outcomes of this model of care in trauma settings is required.

Peer mentor contributions to an early intervention vocational rehabilitation specialist service following trauma: A qualitative study

BackgroundPeer mentors have a role in facilitating the participation, health and well-being of people who have had a traumatic injury. Few studies have explored the involvement of peer mentors in an early intervention vocational rehabilitation (EIVR) service following trauma. ObjectiveThis study aimed to explore the experience of implementing peer support within the context of an EIVR service from the perspectives of the peer mentors themselves, the vocational therapists supervising them, and the patients that received peer mentoring. MethodsSemi-structured interviews were conducted with twenty participants from three groups: peer mentors (n = 4); vocational therapists (n = 3); and patients who received the EIVR intervention (n = 24). Data were thematically analysed. ResultsThree themes were identified: The value of peer input in an EIVR service, The facilitators impacting the value of peer involvement as part of the EIVR service, The challenges impacting peer input as part of an EIVR service. ConclusionsThe inclusion of peer mentors early after major traumatic injury was a unique and valuable addition to the EIVR service. Offering peer support early on in rehabilitation enabled patients to gain a sense of hope for their future, and the expectation that returning to work was a realistic option. The careful selection of peer mentors, and ensuring they receive adequate preparation and ongoing supervision are vital to support their well-being during the intervention. Aiming to match peer mentors with similar injuries and work backgrounds to patients is an important contributor to the likely ongoing engagement of the mentee with the mentor.

Early Intravenous Beta-Blockade with Esmolol in Adults with Severe Traumatic Brain Injury: A Phase 2a Intervention Design Study.

Targeted beta-blockade after severe traumatic brain injury may reduce secondary brain injury by attenuating the sympathoadrenal response. The potential role and optimal dosage for esmolol, a selective, short-acting, titratable beta-1 beta-blocker, as a safe, putative early therapy after major traumatic brain injury has not been assessed. We conducted a single-center, open-label dose-finding study using an adaptive model-based design. Adults (18 years or older) with severe traumatic brain injury and intracranial pressure monitoring received esmolol within 24 h of injury to reduce their heart rate by 15% from baseline of the preceding 4 h while ensuring cerebral perfusion pressure was maintained above 60 mm Hg. In cohorts of three, the starting dosage and dosage increments were escalated according to a prespecified plan in the absence of dose-limiting toxicity. Dose-limiting toxicity was defined as failure to maintain cerebral perfusion pressure, triggering cessation of esmolol infusion. The primary outcome was the maximum tolerated dosage schedule of esmolol, defined as that associated with less than 10% probability of dose-limiting toxicity. Secondary outcomes include 6-month mortality and 6-month extended Glasgow Outcome Scale score. Sixteen patients (6 [37.5%] female patients; mean age 36 years [standard deviation 13 years]) with a median Glasgow Coma Scale score of 6.5 (interquartile range 5-7) received esmolol. The optimal starting dosage of esmolol was 10 μg/kg/min, with increments every 30 min of 5 μg/kg/min, as it was the highest dosage with less than 10% estimated probability of dose-limiting toxicity (7%). All-cause mortality was 12.5% at 6 months (corresponding to a standardized mortality ratio of 0.63). One dose-limiting toxicity event and no serious adverse hemodynamic effects were seen. Esmolol administration, titrated to a heart rate reduction of 15%, is feasible within 24 h of severe traumatic brain injury. The probability of dose-limiting toxicity requiring withdrawal of esmolol when using the optimized schedule is low.

Alcohol is a risk factor for helmet non-use and fatalities in off-road vehicle and motorcycle crashes.

Off-road vehicle (ORV) and motorcycle use is common in Canada; however, risk of serious injury is heightened when these vehicles are operated without helmets and under the influence of alcohol. This study evaluated the impact of alcohol intoxication on helmet non-use and mortality among ORV and motorcycle crashes. Using data collected from the Nova Scotia Trauma Registry, a retrospective analysis (2002-2017) of ORV and motorcycle crashes resulting in major traumatic brain injury was performed. Patients were grouped by blood alcohol concentration (BAC) as negative (< 2 mmol/L), legally intoxicated (2-17.3 mmol/L) or criminally intoxicated (> 17.3 mmol/L). Logistic regression models were constructed to test for helmet non-use and mortality. A total of 424 trauma patients were included in the analysis (220 ORV, 204 motorcycle). Less than half (45%) of patients involved in ORV crashes were wearing helmets and 65% were criminally intoxicated. Most patients involved in motorcycle crashes were helmeted at time of injury (88.7%) and 18% were criminally intoxicated. Those with criminal levels of intoxication had 3.7 times the odds of being unhelmeted and were 3 times more likely to die prehospital compared to BAC negative patients. There were significantly increased odds of in-hospital mortality among those with both legal (OR = 5.63), and criminal intoxication levels (OR = 4.97) compared to patients who were BAC negative. Alcohol intoxication is more frequently observed in ORV versus motorcycle crashes. Criminal intoxication is associated with helmet non-use. Any level of intoxication is a predictor of increased in-hospital mortality.

Follow-up after major traumatic injury: a survey of services in Australian and New Zealand public hospitals

BackgroundIncreased survival from traumatic injury has led to a higher demand for follow-up care when patients are discharged from hospital. It is currently unclear how follow-up care following major trauma is provided to patients, and how, when, and to whom follow-up services are delivered. The aim of this study was to describe the current follow-up care provided to patients and their families who have experienced major traumatic injury in Australia and New Zealand (ANZ).MethodsInformed by Donabedian’s ‘Evaluating the Quality of Medical Care’ model and the Institute of Medicine’s Six Domains of Healthcare Quality, a cross-sectional online survey was developed in conjunction with trauma experts. Their responses informed the final survey which was distributed to key personnel in 71 hospitals in Australia and New Zealand that (i) delivered trauma care to patients, (ii) provided data to the Australasian Trauma Registry, or (iii) were a Trauma Centre.ResultsData were received from 38/71 (53.5%) hospitals. Most were Level 1 trauma centres (n = 23, 60.5%); 76% (n = 16) follow-up services were permanently funded. Follow-up services were led by a range of health professionals with over 60% (n = 19) identifying as trauma specialists. Patient inclusion criteria varied; only one service allowed self-referral (3.3%). Follow-up was within two weeks of acute care discharge in 53% (n = 16) of services. Care activities focused on physical health; psychosocial assessments were the least common. Most services provided care for adults and paediatric trauma (60.5%, n = 23); no service incorporated follow-up for family members. Evaluation of follow-up care was largely as part of a health service initiative; only three sites stated evaluation was specific to trauma follow-up.ConclusionFollow-up care is provided by trauma specialists and predominantly focuses on the physical health of the patients affected by major traumatic injury. Variations exist in terms of patient selection, reason for follow-up and care activities delivered with gaps in the provision of psychosocial and family health services identified. Currently, evaluation of trauma follow-up care is limited, indicating a need for further development to ensure that the care delivered is safe, effective and beneficial to patients, families and healthcare organisations.

Forensic significance and inferential value of PMCT features in charred bodies: A bicentric study

Post-mortem computed tomography (PMCT) is a diagnostic tool that provides essential information in forensic field. This radiological technique can play a pivotal role in personal identification, gunshot injuries, major traumatic injuries, child abuse, drowning asphyxia, embolism, COVID-19, sudden death, and charring cases.Post-mortem imaging can be used to investigate charred bodies as it allows the forensic examiner to distinguish traumatic and heat injuries. PMCT images can also provide additional information to determine whether the individual was alive at the time the fire started.In our bicentric study, we performed PMCT on 15 cases of charred bodies (10 males and 5 females) collected at the Florence University (Florence, Italy) and Catholic University of The Sacred Heart (Rome, Italy) before the external examination and/or full autopsy examination. In both the institutions, PMCT was performed through a Siemens SOMATOM 16-slice CT scanner (Siemens Aktiengesellschaft, Berlin, 2010).The aim of the current study was to obtain unambiguous information that could help determine the cause of death by comparing our PMCT findings with the most recent evidence in the scientific literature. Our investigations focused on the evaluation of bone texture and differences from traumatic fractures, leading also to an improvement in the interpretation of some aspecific findings (e.g., soot) from the integration of the radiological information with the autopsy results.The data obtained in our study support PMCT as a reliable diagnostic tool in the study of charred corpses and represent basic evidence for further applications of radiology in the forensic field.

Major trauma in working-age adults in New Zealand.

To describe the demographic and injury profile of major trauma among 20-65-year-old New Zealanders. A retrospective analysis of routinely collected data from the New Zealand Major Trauma Registry for the period 1 July 2017 to 30 June 2020 was conducted. Sex, age and ethnicity-based rates were then calculated using census-based population estimates to compare the rates of injury across different demographic groups. Of the 4,186 major trauma incidents among 20-65-year-olds in New Zealand during the 3-year period reviewed, 235 died (5.6%). Males accounted for 77% of those injured. Māori (New Zealand's Indigenous population) had significantly higher rates of major trauma (79.2 per 100,000; 95% confidence interval [CI] 74.4-84.3) compared to non-Māori (44.4 per 100,000; 95% CI 42.9-46.0). The most common cause of injury was transport-related incidents (63%; n=2,632/4,186), followed by falls (19%; n=788/4,186). Demographic characteristics have a significant relationship with major trauma injuries among 20-65-year-old New Zealanders. Continued injury prevention efforts focussing on males, Māori and transport incidents are required. Interventions that improve the safety of roads, such as lane separators, speed limits and raised intersections, should be implemented in high-crash-risk areas to reduce risk.

Caregiver reported long-term outcomes in children with major trauma and traumatic brain injuries: A single-centre retrospective study.

We aim to investigate the functional outcomes and long-term health-related quality of life (HRQOL) in children with major trauma associated with traumatic brain injury (TBI). We performed a retrospective review of records among patients >2 and ≤16 years old in a tertiary paediatric hospital between January 2014 and October 2019 with major trauma (Injury Severity Score of ≥16) and TBI of all severities. We recorded each child's Glasgow Outcome Scale-Extended Pediatric Version (GOS-E Peds) at 12 months post-injury and Pediatric Quality of Life Inventory (PedsQL) scores at 6 and 12 months post-injury based on the parent proxy-report scales. We included 53 patients with a median age of 9.0 years old (interquartile range 2.3-15.5). Most injuries were due to falls (30, 56.6%) or road traffic collisions (15, 28.3%); 41 patients (77.3%) required intensive care while 30 patients (56.6%) underwent neurosurgical intervention. Most patients (43, 81.1%) had GOS-E Peds scores of ≤2 at 12 months post-injury. We reported a significant mean difference between the 6- and 12-month parent-reported scores for physical functioning (6.6, 95% confidence interval [CI] 0.3-12.8, P=0.041), psychosocial functioning (4.1, 95% CI 1.0-7.2, P=0.012) and overall scores (5.0, 95% CI 1.4-8.7, P=0.008). Compared with the validated PedsQL scores, our mean scores were higher across all domains at 12 months. With current standard of care, parents of children with major trauma and TBI reported gains in quality of life, physical, psychosocial and overall function between 6 and 12 months post-injury.

EMS Treatment Guidelines in Major Traumatic Brain Injury With Positive Pressure Ventilation.

The Excellence in Prehospital Injury Care (EPIC) study demonstrated improved survival in patients with severe traumatic brain injury (TBI) following implementation of the prehospital treatment guidelines. The impact of implementing these guidelines in the subgroup of patients who received positive pressure ventilation (PPV) is unknown. To evaluate the association of implementation of prehospital TBI evidence-based guidelines with survival among patients with prehospital PPV. The EPIC study was a multisystem, intention-to-treat study using a before/after controlled design. Evidence-based guidelines were implemented by emergency medical service agencies across Arizona. This subanalysis was planned a priori and included participants who received prehospital PPV. Outcomes were compared between the preimplementation and postimplementation cohorts using logistic regression, stratified by predetermined TBI severity categories (moderate, severe, or critical). Data were collected from January 2007 to June 2017, and data were analyzed from January to February 2023. Implementation of the evidence-based guidelines for the prehospital care of patient with TBI. The primary outcome was survival to hospital discharge, and the secondary outcome was survival to admission. Among the 21 852 participants in the main study, 5022 received prehospital PPV (preimplementation, 3531 participants; postimplementation, 1491 participants). Of 5022 included participants, 3720 (74.1%) were male, and the median (IQR) age was 36 (22-54) years. Across all severities combined, survival to admission improved (adjusted odds ratio [aOR], 1.59; 95% CI, 1.28-1.97), while survival to discharge did not (aOR, 0.94; 95% CI, 0.78-1.13). Within the cohort with severe TBI but not in the moderate or critical subgroups, survival to hospital admission increased (aOR, 6.44; 95% CI, 2.39-22.00), as did survival to discharge (aOR, 3.52; 95% CI, 1.96-6.34). Among patients with severe TBI who received active airway interventions in the field, guideline implementation was independently associated with improved survival to hospital admission and discharge. This was true whether they received basic airway interventions or advanced airways. These findings support the current guideline recommendations for aggressive prevention/correction of hypoxia and hyperventilation in patients with severe TBI, regardless of which airway type is used.

Severe thermal and major traumatic injury results in elevated plasma concentrations of total heme that are associated with poor clinical outcomes and systemic immune suppression.

Traumatic and thermal injuries result in a state of systemic immune suppression, yet the mechanisms that underlie its development are poorly understood. Released from injured muscle and lysed red blood cells, heme is a damage associated molecular pattern with potent immune modulatory properties. Here, we measured plasma concentrations of total heme in over 200 traumatic and thermally-injured patients in order to examine its relationship with clinical outcomes and post-injury immune suppression. Blood samples were collected from 98 burns (≥15% total body surface area) and 147 traumatically-injured (injury severity score ≥8) patients across the ultra-early (≤1 hour) and acute (4-72 hours) post-injury settings. Pro-inflammatory cytokine production by lipopolysaccharide (LPS) challenged whole blood leukocytes was studied, and plasma concentrations of total heme, and its scavengers haptoglobin, hemopexin and albumin measured, alongside the expression of heme-oxygenase-1 (HO-1) in peripheral blood mononuclear cells (PBMCs). LPS-induced tumour necrosis factor-alpha (TNF-α) production by THP-1 cells and monocytes following in vitro heme treatment was also examined. Burns and traumatic injury resulted in significantly elevated plasma concentrations of heme, which coincided with reduced levels of hemopexin and albumin, and correlated positively with circulating levels of pro and anti-inflammatory cytokines. PBMCs isolated from trauma patients 4-12 and 48-72 hours post-injury exhibited increased HO-1 gene expression. Non-survivors of burn injury and patients who developed sepsis, presented on day 1 with significantly elevated heme levels, with a difference of 6.5 µM in heme concentrations corresponding to a relative 52% increase in the odds of post-burn mortality. On day 1 post-burn, heme levels were negatively associated with ex vivo LPS-induced TNF-α and interleukin-6 production by whole blood leukocytes. THP-1 cells and monocytes pre-treated with heme exhibited significantly reduced TNF-α production following LPS stimulation. This impairment was associated with decreased gene transcription, reduced activation of extracellular signal-regulated kinase 1/2 and an impaired glycolytic response. Major injury results in elevated plasma concentrations of total heme that may contribute to the development of endotoxin tolerance and increase the risk of poor clinical outcomes. Restoration of the heme scavenging system could be a therapeutic approach by which to improve immune function post-injury.

Pre-oxygenation using high-flow nasal oxygen versus tight facemask in trauma patients undergoing emergency anaesthesia.

Patients suffering from major traumatic injuries frequently require emergency anaesthesia. Due to often compromised physiology and the time-sensitive management, trauma patients may be more prone to desaturate during induction of anaesthesia. We hypothesised that pre-oxygenation using high-flow nasal oxygen would decrease the risk of desaturation during induction of anaesthesia in trauma patients and the study therefore aimed to compare the frequency of desaturation when pre-oxygenation was performed with high-flow nasal oxygen or a traditional facemask. This exploratory, prospective, before-and-after study was conducted at the Karolinska University Hospital, Sweden. Adult (≥18 years of age) patients suffering major traumatic injuries needing emergency anaesthesia were included around the clock. Patients were pre-oxygenated using a tight-fitting facemask during the first nine months of enrollment. High-flow nasal oxygen was then introduced as a method for pre-oxygenation of trauma patients. The primary outcome was the proportion of patients desaturating <93% during induction of anaesthesia, assessed from the start of pre-oxygenation until one minute after intubation. Secondary outcomes included perceived difficulty of pre-oxygenation among anaesthetists (assessed on a scale between 1 and 10) and safety outcomes, such as incidence of regurgitations and intracranial gas (assessed radiologically). Data from 96 patients were analysed. Facemask pre-oxygenation was performed in 66 patients, while 30 patients were pre-oxygenated with high-flow nasal oxygen. The most frequent trauma mechanisms were stabbing injuries (n = 34 (35%)) and fall injuries (n = 21 (22%)). There were no differences in patient characteristics between the groups. Eight (12%) versus three (10%) patients desaturated <93% in the facemask and high-flow nasal oxygen group respectively, OR 0.81 (95% CI 0.20-3.28), p = .76. Anaesthetists assessed pre-oxygenation using high-flow nasal oxygen as easier compared to facemask pre-oxygenation. No patient in any group showed signs of regurgitation. Among patients with facial or skull fractures requiring anaesthesia before radiology was performed, intracranial gas was seen in four (40%) patients pre-oxygenated with a facemask and in no patient pre-oxygenated with HFNO (p = .23). In this prospective study investigating trauma patients undergoing emergency anaesthesia, we could not see any difference in the number of patients desaturating when pre-oxygenation was performed with high-flow nasal oxygen compared to a tight-fitting facemask. Pre-oxygenation using high-flow nasal oxygen was assessed as easier compared to facemask pre-oxygenation.

Functional survival of cementless trapeziometacarpal total joint arthroplasty after upper extremity trauma

IntroductionOur purpose with this publication is to document the survival of uncemented and unconstrained total trapeziometacarpal arthroplasty after energy trauma to the upper extremity. Material and MethodsFrom 1999 to the present, ten patients carrying total TMC arthroplasty suffered major traumatic injuries on the hand. Eight patients had fractures of the distal radius, one patient had scapho-lunate dissociation and one patient had a dorsal pullout of the triquetrum. A clinical and radiological examination of the patients after the trauma was carried out and compared with the pre-traumatic prosthesis status. ResultsThree patients required surgical intervention for the associated traumatic injury. The postraumatic clinical and functional follow-up of the patients was good, and no differences were documented with respect to mobility, strength and pain at the level of the thumb with respect to the prior to the trauma. No signs of loosening, instability or alteration in the alignment of the components of the protheses were observed in the radiological examinations following the trauma. ConclusionsThere is a high survival rate of uncemented total trapeziometacarpal arthroplasty in the long term, even in the face of energy trauma. It is then a safe implant. Despite of being non-constrained, a good alignment of the prosthetic components is the key to avoid dislocation of the prosthesis.

EGS P06 Pattern of oesophago-gastric injuries and its outcome in major trauma and tertiary UGI centre

Abstract Background Oesophago-gastric injuries in major trauma are relatively rare. These injuries are known to be associated with high morbidity and mortality. Major trauma involving oesophagus and stomach are linked with high velocity, high impact blunt or penetrating force. There is also a strong association between oesophago-gastric injuries and other systemic injuries including thoracic, major vessels, skull, brain and abdominal viscerae. In this study we aimed to evaluate the pattern of injury in oesophageal and gastric major trauma its association with widely used injury severity score (ISS), multi organ system involvement, survival and factors affecting mortality. Methods Patients presenting between January 2012 and December 2022 as major trauma as moderate / severe trauma (ISS &amp;gt; 9) with oesophageal and gastric injuries were included in this study. Retrospective analysis was carried out on prospectively maintained trauma data base in an urban major trauma centre with specialist tertiary upper GI cover. Mechanism of injury, ISS and mortality were calculated. Analysis was carried out on variables to identify factors contributing to overall index admission mortality. MedCalc ® was used to perform statistical analysis. Results A total of 8984 patients presented in urban major trauma centre with moderate to severe trauma (ISS &amp;gt;9). Among them 13 had gastric injuries and 3 had oesophageal injuries (total n=16). Mechanism of injury in gastric patients was blunt force in 8 (61.5%) and penetrating force was in 5 (38.5%) patients whereas all oesophageal injuries were linked with penetrating trauma. Median ISS in gastric injuries was 17 and in oesophageal injuries was 34. Overall mortality was 31.2%(n=5). Variables including high ISS, thoracic injury, diaphragmatic rupture, skull injuries &amp; blood transfusion were linked with mortality on multivariate logistic regression. Conclusions Our study finds an association of oesophago-gastric injuries with high impact penetrating and blunt trauma. Presence of oesophageal and gastric injuries are surrogate indicators of severity of trauma, it is not only associated with high ISS but also has relatively high mortality. Therefore, early involvement of specialist senior decision maker in time critical setting is recommended. Due to scarce volume of OG trauma, national UGI trauma collaborative can be helpful to share experience, learn lessons and promote research.

A Ten-Year Retrospective Cohort Study on Neck Collar Immobilization in Trauma Patients with Head and Neck Injuries.

Background and Objectives: In the context of prehospital care, spinal immobilization is commonly employed to maintain cervical stability in head and neck injury patients. However, its use in cases of unclear consciousness or major trauma patients is often precautionary, pending the exclusion of unstable spinal injuries through appropriate diagnostic imaging. The impact of prehospital C-spinal immobilization in these specific patient populations remains uncertain. Materials and Methods: We conducted a retrospective cohort study at Taipei Tzu Chi Hospital from January 2009 to May 2019, focusing on trauma patients suspected of head and neck injuries. The primary outcome assessed was in-hospital mortality. We employed multivariable logistic regression to investigate the relationship between prehospital C-spine immobilization and outcomes, while adjusting for various factors such as age, gender, type of traumatic brain injury, Injury Severity Score (ISS), Revised Trauma Score (RTS), and activation of trauma team. Results: Our analysis encompassed 2733 patients. Among these, patients in the unclear consciousness group (GCS ≤ 8) who underwent C-spine immobilization exhibited a higher mortality rate than those without immobilization. However, there was no statistically significant difference in mortality among patients with alert consciousness (GCS > 8). Multivariable logistic regression analysis revealed that advanced age (age ≥ 65), unclear consciousness (GCS ≤ 8), major traumatic injuries (ISS ≥ 16 and RTS ≤ 7), and the use of neck collars for immobilization (adjusted OR: 1.850, 95% CI: 1.240-2.760, p = 0.003) were significantly associated with an increased risk of mortality. Subgroup analysis indicated that C-spine immobilization was significantly linked to an elevated risk of mortality in older adults (age ≥ 65), patients with unclear consciousness (GCS ≤ 8), those with major traumatic injuries (ISS ≥ 16 and RTS ≤ 7), and individuals in shock (shock index > 1). Conclusions: While our findings do not advocate for the complete abandonment of neck collars in all suspected head and neck injury patients, our study suggests that prehospital cervical and spinal immobilization should be applied more selectively in certain head and neck injury populations. This approach is particularly relevant for older individuals (age ≥ 65), those with unclear consciousness (GCS ≤ 8), individuals experiencing major traumatic injuries (ISS ≥ 16 or RTS ≤ 7), and patients in a state of shock (shock index ≥ 1). Our study employs a retrospective cohort design, which may introduce selection bias. Therefore, in the future, there is a need for confirmation of our results through a two-arm randomized controlled trial (RCT) arises, as this design is considered ideal for addressing this issue.

Relationship between systolic blood pressure and mortality in older vs younger trauma patients – a retrospective multicentre observational study

BackgroundThe population of older trauma patients is increasing. Those patients have heterogeneous presentations and need senior-friendly triaging tools. Systolic blood pressure (SBP) is commonly used to assess injury severity, and some authors advocated adjusting SBP threshold for older patients. We aimed to describe and compare the relationship between mortality and SBP in older trauma patients and their younger counterparts.MethodsWe included patients admitted to three level-I trauma centres and performed logistic regressions with age and SBP to obtain mortality curves. Multivariable Logistic regressions were performed to measure the association between age and mortality at different SBP ranges. Subgroup analyses were conducted for major trauma and severe traumatic brain injury admissions.ResultsA total of 47,661 patients were included, among which 12.9% were aged 65–74 years and 27.3% were ≥ 75 years. Overall mortality rates were 3.9%, 8.1%, and 11.7% in the groups aged 16–64, 65–74, and ≥ 75 years, respectively. The relationship between prehospital SBP and mortality was nonlinear (U-shape), mortality increased with each 10 mmHg SBP decrement from 130 to 50 mmHg and each 10-mmHg increment from 150 to 220 mmHg across all age groups. Older patients were at higher odd for mortality in all ranges of SBP. The highest OR in patients aged 65–74 years was 3.67 [95% CI: 2.08–6.45] in the 90–99 mmHg SBP range and 7.92 [95% CI: 5.13–12.23] for those aged ≥ 75 years in the 100–109 mmHg SBP range.ConclusionThe relationship between SBP and mortality is nonlinear, regardless of trauma severity and age. Older age was associated with a higher odd of mortality at all SBP points. Future triage tools should therefore consider SBP as a continuous rather than a dichotomized predictor.

Stepped collaborative care for pain and posttraumatic stress disorder after major trauma: a randomized controlled feasibility trial

Purpose To examine feasibility and acceptability of providing stepped collaborative care case management targeting posttraumatic stress disorder (PTSD) and pain symptoms after major traumatic injury. Materials and methods Participants were major trauma survivors in Victoria, Australia, at risk of persistent pain or PTSD with high baseline symptoms. Participants were block-randomized, stratified by compensation-status, to the usual care (n = 15) or intervention (n = 17) group (46% of eligible patients). The intervention was adapted from existing stepped collaborative care interventions with input from interdisciplinary experts and people with lived experience in trauma and disability. The proactive case management intervention targeted PTSD and pain management for 6-months using motivational interviewing, cognitive behavioral therapy strategies, and collaborative care. Qualitative interviews explored intervention acceptability. Results Intervention participants received a median of 7 h case manager contact and reported that they valued the supportive and non-judgmental listening, and timely access to effective strategies, resources, and treatments post-injury from the case manager. Participants reported few disadvantages from participation, and positive impacts on symptoms and recovery outcomes consistent with the reduction in PTSD and pain symptoms measured at 1-, 3- and 6-months. Conclusions Stepped collaborative care was low-cost, feasible, and acceptable to people at risk of PTSD or pain after major trauma. IMPLICATIONS FOR REHABILITATION After hospitalization for injury, people can experience difficulty accessing timely support to manage posttraumatic stress, pain and other concerns. Stepped case management-based interventions that provide individualized support and collaborative care have reduced posttraumatic stress symptom severity for patients admitted to American trauma centers. We showed that this model of care could be adapted to target pain and mental health in the trauma system in Victoria, Australia. The intervention was low cost, acceptable and highly valued by most participants who perceived that it helped them use strategies to better manage post-traumatic symptoms, and to access clinicians and treatments relevant to their needs.
