Background The benefit–risk ratio of prophylactic non-invasive ventilation (NIV) and high-flow nasal oxygen therapy (HFNC-O 2 ) during the early stage of blunt chest trauma remains controversial because of limited data. The main objective of this study was to compare the rate of endotracheal intubation between two NIV strategies in high-risk blunt chest trauma patients. Methods The OptiTHO trial was a randomized, open-label, multicenter trial over a two-year period. Every adult patients admitted in intensive care unit within 48 h after a high-risk blunt chest trauma (Thoracic Trauma Severity Score ≥ 8), an estimated PaO 2 /FiO 2 ratio < 300 and no evidence of acute respiratory failure were eligible for study enrollment (Clinical Trial Registration: NCT03943914). The primary objective was to compare the rate of endotracheal intubation for delayed respiratory failure between two NIV strategies: i) a prompt association of HFNC-O 2 and “early” NIV in every patient for at least 48 h with vs. ii) the standard of care associating COT and “late” NIV, indicated in patients with respiratory deterioration and/or PaO 2 /FiO 2 ratio ≤ 200 mmHg. Secondary outcomes were the occurrence of chest trauma-related complications (pulmonary infection, delayed hemothorax or moderate-to-severe ARDS). Results Study enrollment was stopped for futility after a 2-year study period and randomization of 141 patients. Overall, 11 patients (7.8%) required endotracheal intubation for delayed respiratory failure. The rate of endotracheal intubation was not significantly lower in patients treated with the experimental strategy (7% [5/71]) when compared to the control group (8.6% [6/70]), with an adjusted OR = 0.72 (95%IC: 0.20–2.43), p  =  0.60 . The occurrence of pulmonary infection, delayed hemothorax or delayed ARDS was not significantly lower in patients treated by the experimental strategy (adjusted OR = 1.99 [95%IC: 0.73–5.89], p  =  0.18, 0.85 [95%IC: 0.33–2.20], p  =  0.74 and 2.14 [95%IC: 0.36–20.77], p  =  0.41 , respectively). Conclusion A prompt association of HFNC-O 2 with preventive NIV did not reduce the rate of endotracheal intubation or secondary respiratory complications when compared to COT and late NIV in high-risk blunt chest trauma patients with non-severe hypoxemia and no sign of acute respiratory failure.

Background Hemorrhage from intra-abdominal injuries (IAI) is a leading cause of traumatic deaths in children. Concern over misdiagnosing IAIs has resulted in excessive use of abdominal computed tomography (CT). Despite its many benefits, CT presents risks to children most notably radiation-induced malignancies. Thus, we must safely limit abdominal CT evaluation to those at non-negligible risk. The focused assessment with sonography for trauma (FAST) examination uses abdominal ultrasonography to detect the presence of intraperitoneal fluid in injured patients and may decrease abdominal CT use in some children. Limited and conflicting data exists on the utility of the FAST examination in children. A large multicenter study is thus necessary to determine if the FAST examination should routinely be included in the diagnostic evaluation of injured children. Methods This is a multicenter, randomized controlled clinical trial to assess the impact of the FAST examination on the initial evaluation of children with blunt abdominal trauma. Enrolled participants will be randomized 1:1 to the FAST examination plus routine care or routine care alone during their initial emergency department (ED) evaluation. The study will enroll 3194 (initial sample size) to 4346 (second sample size) children at six diverse sites. The primary outcomes are as follows: (1) The proportion of abdominal CT in the initial 24 h of care and (2) the proportion of missed or delayed diagnoses of IAIs. Secondary outcomes include (1) ED length of stay, (2) hospitalization proportion and length of hospital stay, (3) physician suspicion of IAI, (4) the proportion of abdominal CT use in the subgroup of children 0 to 3 years old, and (5) laparotomy proportion. Hospitalized participants will be followed through their stay, and guardians of those discharged from the ED will be contacted after 1 week to assess their status. Discussion The study will determine if the FAST examination results in a safe reduction of CT use in injured children and will provide definitive evidence if the FAST examination should be routinely implemented in the initial evaluation of children with blunt abdominal trauma.

Rib fractures, which are among the most common injuries in blunt thoracic trauma, are usually encountered in Emergency Departments. Kinesiotape (KT) is a drug-free elastic therapeutic tape used for treating various musculoskeletal problems such as injury, dysfunction and pain. We aimed to investigate whether kinesotaping should be used safely and effectively in rib fractures in emergency setting. This was a prospective, randomized controlled study conducted in an Emergency Department of a University Hospital. Patients diagnosed with isolated rib fractures were included in the study. Pain severity of patients assessed with 0–10 cm visual analog scale (VAS), then patients assigned into 2 treatment groups. One of them received treatment with flurbiprofen 200 mg/day and the other group received kinesiotaping in addition to the same oral therapy. On the 4th day of the procedure, both groups were assessed with VAS in the followup visit. Total of 82 patients presented with rib fractures, 52 of them were excluded. Remaining 30 constituted the study group and randomly allocated to kinesiotaping (n = 16) or control group (n = 14). In both groups, pain intensity on the 4th day was significantly reduced when compared with baseline (p for both<0.01). Additionally, considering the reducing the pain intensity on 4th day, kinesiotaping was significantly superior than the control group (p < 0.01). This study investigated the use of kinesiotaping in emergency departments. When compared to NSAID therapy alone, combined kinesiotaping and NSAID therapy appears to be more effective in terms of pain reduction in rib fractures.

Background Multi-organ dysfunction syndrome and multi-organ failure are the leading causes of late death in patients sustaining severe blunt trauma. So far, there is no established protocol to mitigate these sequelae. This study assessed the effect of hemoperfusion using resin-hemoadsorption 330 (HA330) cartridges on mortality and complications such as acute respiratory distress syndrome (ARDS) and systemic inflammatory response syndrome (SIRS) among such patients. Methods This quasi-experimental study recruited patients ≥ 15 years of age with blunt trauma, injury severity score (ISS) ≥ 15, or initial clinical presentation consistent with SIRS. They were divided into two groups: the Control group received only conventional acute care, while the case group received adjunctive hemoperfusion. P-values less than 0.05 were statistically significant. Results Twenty-five patients were included (Control and Case groups: 13 and 12 patients). The presenting vital signs, demographic and injury-related features (except for thoracic injury severity) were similar (p > 0.05). The Case group experienced significantly more severe thoracic injuries than the Control group (Thoracic AIS, median [IQR]: 3 [2–4] vs. 2 [0–2], p = 0.01). Eleven and twelve patients in the Case group had ARDS and SIRS before the hemoperfusion, respectively, and these complications were decreased considerably after hemoperfusion. Meanwhile, the frequency of ARDS and SIRS did not decrease in the Control group. Hemoperfusion significantly reduced the mortality rate in the Case group compared to the Control group (three vs. nine patients, p = 0.027). Conclusions Adjunctive Hemoperfusion using an HA330 cartridge decreases morbidity and improves outcomes in patients suffering from severe blunt trauma.

BackgroundThe aim was to complete a feasibility study that would test the methods of the main trial, that will investigate whether early thoracic and shoulder girdle exercises reduce chronic pain in patients with blunt chest wall trauma, when compared with normal care.MethodsA single centre, parallel, feasibility randomised controlled trial was completed at a University Teaching Hospital in Wales between June and September 2019. Adult patients with blunt chest wall trauma, admitted to hospital for greater than 24 hours, with no concurrent, immediately life-threatening injuries, were included. The intervention was a simple physiotherapy programme comprising thoracic and shoulder girdle exercises. Feasibility outcome measures included: primary outcomes: (1) 80% or more of identified eligible patients were approached for potential recruitment to the trial (2) 30% or less of approached, eligible patients dissented to participate in the trial; secondary outcomes: (3) follow-up data for patient secondary outcomes can be collected for 80% or more of patients, (4) there should be no greater than 10% increase in serious adverse events in the intervention group compared with the control group.ResultsA total of 19/19 (100%) patients were deemed eligible for the trial and were approached for participation, 5/19 (26%) eligible patients declined to participate in the trial, follow-up data were collected for n=10/14 (71%) patients and there were no serious adverse events reported in either group.ConclusionsWe have demonstrated that a fully powered randomised clinical trial of the EarLy Exercise in blunt Chest wall Trauma Trial is feasible.Trial registration number ISRCTN16197429

IntroductionThe aim of this study was to compare observation and early drainage by ureteral stenting in patients with blunt renal trauma and urinary extravasation.Materials and methodsA retrospective national multicenter study was performed including all patients admitted for renal trauma at 17 hospitals between 2005 and 2015. Patients presenting with a urinary extravasation on initial imaging were considered for inclusion. Patients were divided in two groups according to the initial approach: observation vs. early drainage by ureteral stent (within 48 h after admission). The primary endpoint was the persistence of urinary extravasation on follow-up imaging.ResultsOut of 1799 patients with renal trauma, 238 were included in the analysis (57 in the early drainage and 181 in the observation group). In the early drainage group, 29 patients had persistent urinary extravasation vs. 77 in the observation group (50.9% vs. 42.5%; p value = 0.27). The rates of secondary upper urinary tract drainage did not differ significantly between the early drainage group (26.4%) and the observation group (16%) (p = 0.14). There were no statistically significant differences between the two groups in terms of secondary nephrectomy (0% vs. 2.8%; p = 0.34), and death from trauma (0% vs. 1.8%; p = 0.99). In multivariate analysis, early drainage remained not statistically associated with persistence of urinary extravasation on follow-up imaging (OR = 1.35; p = 0.36)ConclusionIn this multicenter cohort, observation was not different from early drainage in terms of persistent urinary extravasation after grade IV blunt renal trauma. Further randomized controlled prospective trials are needed to confirm these findings.

IntroductionChronic pain and disability are now well-recognised long-term complications of blunt chest wall trauma. Limited research exists regarding therapeutic interventions that can be used to address these complications. A recent feasibility study was completed testing the methods of a definitive trial. This protocol describes the proposed definitive trial, the aim of which is to investigate the impact of an early exercise programme on chronic pain and disability in patients with blunt chest wall trauma.Methods/analysisThis mixed-methods, multicentre, parallel randomised controlled trial will run in four hospitals in Wales and one in England over 12-month recruitment period. Patients will be randomised to either the control group (routine physiotherapy input) or the intervention group (routine physiotherapy input plus a simple exercise programme completed individually by the patient). Baseline measurements including completion of two surveys (Brief Pain Inventory and EuroQol 5-dimensions, 5-Levels) will be obtained on initial assessment. These measures and a client services receipt inventory will be repeated at 3-month postinjury. Analysis of outcomes will focus on rate and severity of chronic pain and disability, cost-effectiveness and acceptability of the programme by patients and clinicians. Qualitative feedback regarding acceptability will be obtained through patient and clinician focus groups.Ethics/disseminationLondon Riverside Research Ethics Committee (Reference number: 21/LO/0782) and the Health Research Authority granted approval for the trial in December 2021. Patient recruitment will commence in February 2022. Planned dissemination is through publication in a peer-reviewed Emergency Medicine Journal, presentation at appropriate conferences and to stakeholders at professional meetings.Trial registration numberISRCTN65829737; Pre-results.

There is continued debate regarding the optimal period of bed-rest and in-hospital monitoring for non-operative management of solid organ injury following blunt trauma. Single center, prospective, observational study of blunt solid organ injuries from 07/2014–02/2016, managed initially without surgical or angiographic intervention. Early ambulation was defined as ≤24 h. 79 patients met inclusion criteria, with 36 (45.6%) in the early ambulation group and 43 (54.4%) in the late ambulation group. There were zero complications in the early ambulation group, and three complications in the late ambulation group (complications, p = 0.246; further interventions, p = 0.498). Median ICU LOS was zero days and three days for early vs. late ambulation, p = 0.001. Median total LOS was two days and five days for early vs. late ambulation, p < 0.001. Early ambulation is safe in patients undergoing non-operative management of their solid organ injury, and may result in a reduced length of stay.

ObjectiveA new prognostic model has been developed and externally validated, the aim of which is to assist in the management of the blunt chest wall trauma patient in the emergency department (ED). The aim of this trial is to assess the feasibility and acceptability of a definitive impact trial investigating the clinical and cost-effectiveness of a new prognostic model for the management of patients with blunt chest wall trauma in the ED.DesignStepped wedge feasibility trial.SettingFour EDs in England and Wales.ParticipantsAdult blunt chest wall trauma patients presenting to the ED with no concurrent, life-threatening injuries.InterventionA prognostic model (the STUMBL score) to guide clinical decision-making.Outcome measuresPrimary: participant recruitment rate and clinicians’ use of the STUMBL score. Secondary: composite outcome measure (mortality, pulmonary complications, delayed upgrade in care, unplanned representations to the ED), physical and mental components of quality of life, clinician feedback and health economic data gathering methodology for healthcare resource utilisation.ResultsQuantitative data were analysed using the intention-to-treat principle. 176 patients were recruited; recruitment targets were achieved at all sites. Clinicians used the model in 96% of intervention cases. All feasibility criteria were fully or partially met. After adjusting for predefined covariates, there were no statistically significant differences between the control and intervention periods. Qualitative analysis highlighted that STUMBL was well-received and clinicians would support a definitive trial. Collecting data on intervention costs, health-related quality of life and healthcare resource use was feasible.DiscussionWe have demonstrated that a fully powered randomised clinical trial of the STUMBL score is feasible and desirable to clinicians. Minor methodological modifications will be made for the full trial.Trial registration number ISRCTN95571506; Post-results.
