Development and validation of the tic score for early detection of traumatic coagulopathy upon hospital admission: a cohort study.

BACKGROUND: Critically injured patients need rapid and appropriate hemostatic treatment, which requires prompt identification of trauma-induced coagulopathy (TIC) upon hospital admission. We developed and validated the performance of a clinical score based on prehospital resuscitation parameters and vital signs at hospital admission for early diagnosis of TIC. METHODS: The score was derived from a level-1 trauma center registry (training set). It was then validated on data from two other level-1 trauma centers: first on a trauma registry (retrospective validation set), and then on a prospective cohort (prospective validation set). TIC was defined as a PTratio > 1.2 at hospital admission. Prehospital (vital signs and resuscitation care) and admission data (vital signs and laboratory parameters) were collected. We considered parameters independently associated with TIC in the score (binomial logistic regression). We estimated the score's performance for the prediction of TIC. RESULTS: A total of 3489 patients were included, and among these a TIC was observed in 22% (95% CI 21-24%) of cases. Five criteria were identified and included in the TIC Score: Glasgow coma scale < 9, Shock Index > 0.9, hemoglobin < 11 g.dL-1, prehospital fluid volume > 1000 ml, and prehospital use of norepinephrine (yes/no). The score, ranging from 0 and 9 points, had good performance for the identification of TIC (AUC: 0.82, 95% CI: 0.81-0.84) without differences between the three sets used. A score value < 2 had a negative predictive value of 93% and was selected to rule-out TIC. Conversely, a score value ≥ 6 had a positive predictive value of 92% and was selected to indicate TIC. CONCLUSION: The TIC Score is quick and easy to calculate and can accurately identify patients with TIC upon hospital admission.

Prediction of neurocritical care intensity through automated infrared pupillometry and transcranial doppler in blunt traumatic brain injury: the NOPE study.

PURPOSE: This pilot study aimed to determine the capacity of automated infrared pupillometry (AIP) alone and in combination with transcranial doppler (TCD) on admission to rule out need for intense neuroAQ2 critical care (INCC) in severe traumatic brain injury (TBI). METHODS: In this observational pilot study clinicians performed AIP and TCD measurements on admission in blunt TBI patients with a Glasgow Coma Score (GCS) < 9 and/or motor score < 6. A Neurological Pupil index (NPi) < 3, Pulsatility Index (PI) > 1,4 or diastolic blood flow velocity (dV) of < 20 cm/s were used to rule out the need for INCC (exceeding the tier 0 Seattle Consensus Conference). The primary outcome was the negative likelihood ratio (nLR) of NPi < 3 alone or in combination with TCD to detect need for INCC. RESULTS: A total of 69 TBI patients were included from May 2019 to September 2020. Of those, 52/69 (75%) median age was 45 [28-67], median prehospital GCS of 7 [5-8], median Injury Severity Scale of 13.0 [6.5-25.5], median Marshall Score of 4 [3-5], the median Glasgow Outcome Scale at discharge was 3 [1-5]. NPi < 3 was an independent predictor of INCC. NPi demonstrated a nLR of 0,6 (95%CI 0.4-0.9; AUROC, 0.65, 95% CI 0.51-0.79), a combination of NPi and TCD showed a nLR of 0.6 (95% CI 0.4-1.0; AUROC 0.67 95% CI 0.52-0.83) to predict INCC. CONCLUSION: This pilot study suggests a possible useful contribution of NPi to determine the need for INCC in severe blunt TBI patients on admission.

Early management of adult traumatic spinal cord injury in patients with polytrauma: a consensus and clinical recommendations jointly developed by the World Society of Emergency Surgery (WSES) & the European Association of Neurosurgical Societies (EANS).

BACKGROUND: The early management of polytrauma patients with traumatic spinal cord injury (tSCI) is a major challenge. Sparse data is available to provide optimal care in this scenario and worldwide variability in clinical practice has been documented in recent studies. METHODS: A multidisciplinary consensus panel of physicians selected for their established clinical and scientific expertise in the acute management of tSCI polytrauma patients with different specializations was established. The World Society of Emergency Surgery (WSES) and the European Association of Neurosurgical Societies (EANS) endorsed the consensus, and a modified Delphi approach was adopted. RESULTS: A total of 17 statements were proposed and discussed. A consensus was reached generating 17 recommendations (16 strong and 1 weak). CONCLUSIONS: This consensus provides practical recommendations to support a clinician's decision making in the management of tSCI polytrauma patients.

Ferric derisomaltose and tranexamic acid, combined or alone, for reducing blood transfusion in patients with hip fracture (the HiFIT trial): a multicentre, 2 × 2 factorial, randomised, double-blind, controlled trial.

BACKGROUND: Anaemia and blood transfusion are associated with poor outcomes after hip fracture. We evaluated the efficacy of intravenous iron and tranexamic acid in reducing blood transfusions after hip fracture surgery. METHODS: In this double-blind, randomised, 2 × 2 factorial trial, we recruited adults hospitalised for hip fractures in 12 medical centres in France who had preoperative haemoglobin concentrations between 9·5 and 13·0 g/dL. We randomly allocated participants (1:1:1:1), via a secure web-based service, to ferric derisomaltose (20 mg/kg intravenously) and tranexamic acid (1 g bolus followed by 1 g over 8 h intravenously at inclusion and 3 g topically during surgery), iron plus placebo (normal saline), tranexamic acid plus placebo, or double placebo. Unmasked nurses administered study drugs; participants and other clinical and research staff remained masked to treatment allocation. The primary outcome was the percentage of patients transfused during hospitalisation (or by day 30). The primary analysis included all randomised patients. This study is registered on ClinicalTrials.gov (NCT02972294) and is closed to new participants. FINDINGS: Of 413 patients (51-104 years old, median [IQR] 86 [78-91], 312 [76%] women, 101 [24%] men), 104 received iron plus tranexamic acid, 103 iron plus placebo, 103 tranexamic acid plus placebo, and 103 double placebo between March 31, 2017 and June 18, 2021 (study stopped early for efficacy after the planned interim analysis done on the first 390 patients included on May 25, 2021). Data for the primary outcome were available for all participants. Among patients on double placebo, 31 (30%) were transfused versus 16 (15%) on both drugs (relative risk 0·51 [98·3% CI 0·27-0·97]; p=0·012). 27 (26%) participants on iron (0·81 [0·50-1·29]; p=0·28) and 28 (27%) on tranexamic acid (0·85 [0·54-1·33]; p=0·39) were transfused. 487 adverse events were reported with similar event rates among the groups; among prespecified safety endpoints, severe postoperative anaemia (haemoglobin <8 g/dL) was more frequent in the double placebo group. Main common adverse event were sepsis, pneumonia, and urinary infection, with similar rates among all groups. INTERPRETATION: In patients hospitalised for hip fracture surgery with a haemoglobin concentration 9·5-13·0 g/dL, preoperative infusion of ferric derisomaltose plus tranexamic acid reduced the risk of blood transfusion by 50%. Our results suggest that combining treatments from two different pillars improves patient blood-management programmes. Either treatment alone did not reduce transfusion rates, but we might not have had the power to detect it. FUNDING: French Ministry of Health, HiFIT trial.

Association of Organizational Pathways With the Delay of Emergency Surgery.

Importance: Delayed admission of patients with surgical emergencies to the operating room occurs frequently and is associated with poor outcomes. In France, where 3 distinct organizational pathways in hospitals exist (a dedicated emergency operating room and team [DET], a dedicated operating room in a central operating theater [DOR], and no dedicated structure or team [NOR]), neither the incidence nor the influence of delayed urgent surgery is known, and no guidelines are available to date. Objective: To examine the overall frequency of delayed admission of patients with surgical emergencies to the operating room across the 3 organizational pathways in hospitals in France. Design, Setting, and Participants: This prospective multicenter cohort study was conducted in 10 French tertiary hospitals. All consecutive adult patients admitted for emergency surgery from October 5 to 16, 2020, were included and prospectively monitored. Patients requiring pediatric surgery, obstetrics, interventional radiology, or endoscopic procedures were excluded. Exposures: Emergency surgery. Main Outcomes and Measures: The main outcome was the global incidence of delayed emergency surgery across 3 predefined organizational pathways: DET, DOR, and NOR. The ratio between the actual time to surgery (observed duration between surgical indication and incision) and the ideal time to surgery (predefined optimal duration between surgical indication and incision according to the Non-Elective Surgery Triage classification) was calculated for each patient. Surgery was considered delayed when this ratio was greater than 1. Results: A total of 1149 patients were included (mean [SD] age, 55 [21] years; 685 [59.9%] males): 649 in the DET group, 320 in the DOR group, and 171 in the NOR group (missing data: n = 5). The global frequency of surgical delay was 32.5% (95% CI, 29.8%-35.3%) and varied across the 3 organizational pathways: DET, 28.4% (95% CI, 24.8%-31.9%); DOR, 32.2% (95% CI, 27.0%-37.4%); and NOR, 49.1% (95% CI, 41.6%-56.7%) (P < .001). The adjusted odds ratio for delay was 1.80 (95% CI, 1.17-2.78) when comparing NOR with DET. Conclusions and Relevance: In this cohort study, the frequency of delayed emergency surgery in France was 32.5%. Reduced delays were found in organizational pathways that included dedicated theaters and teams. These preliminary results may pave the way for comprehensive large-scale studies, from which results may potentially inform new guidelines for quicker and safer access to emergency surgery.

Early management of isolated severe traumatic brain injury patients in a hospital without neurosurgical capabilities: a consensus and clinical recommendations of the World Society of Emergency Surgery (WSES).

BACKGROUND: Severe traumatic brain-injured (TBI) patients should be primarily admitted to a hub trauma center (hospital with neurosurgical capabilities) to allow immediate delivery of appropriate care in a specialized environment. Sometimes, severe TBI patients are admitted to a spoke hospital (hospital without neurosurgical capabilities), and scarce data are available regarding the optimal management of severe isolated TBI patients who do not have immediate access to neurosurgical care. METHODS: A multidisciplinary consensus panel composed of 41 physicians selected for their established clinical and scientific expertise in the acute management of TBI patients with different specializations (anesthesia/intensive care, neurocritical care, acute care surgery, neurosurgery and neuroradiology) was established. The consensus was endorsed by the World Society of Emergency Surgery, and a modified Delphi approach was adopted. RESULTS: A total of 28 statements were proposed and discussed. Consensus was reached on 22 strong recommendations and 3 weak recommendations. In three cases, where consensus was not reached, no recommendation was provided. CONCLUSIONS: This consensus provides practical recommendations to support clinician's decision making in the management of isolated severe TBI patients in centers without neurosurgical capabilities and during transfer to a hub center.

Time to source control and outcome in community-acquired intra-abdominal infections: The multicentre observational PERICOM study.

BACKGROUND: Optimal management of community-acquired intra-abdominal infections (IAI) requires timely surgical source control and adequate anti-infective treatment. OBJECTIVE: To describe the initial management of community-acquired IAI admitted to the emergency department and assess the association between the length of time to either diagnosis or therapeutic procedures and patient outcomes. DESIGN: A prospective, multicentre, observational study. SETTING: Thirteen teaching hospitals in France between April 2018 and February 2019. PATIENTS: Two hundred and five patients aged at least 18 years diagnosed with community-acquired IAI. MAIN OUTCOME MEASURES: The primary outcome was hospital length of stay. The secondary outcome was hospital mortality. RESULTS: Patients had a mean age of 56 (± 21) years and a median [interquartile] SAPS II of 26 [17 to 34]. Among the study cohort, 18% were postoperatively transferred to intensive care unit and 7% had died by day 28. Median [IQR] time to imaging, antibiotic therapy and surgery were 4 [2 to 6], 7.5 [4 to 12.5] and 9 [5.5 to 17] hours, respectively. The length of time to surgical source control [0.99, 95% confidence interval (CI), 0.98 to 0.99], SOFA greater than 2 [0.36 (95% CI, 0.26 to 0.651)], age greater than 60 years [0.65 (95% CI, 0.45 to 0.94)], generalized peritonitis [0.7 (95% CI, 0.56 to 0.89)] and laparotomy surgery [0.657 (95% CI, 0.42 to 0.78)] were associated with longer hospital length of stay. The duration of time to surgical source control [1.02 (95% CI, 1.01 to 1.04)], generalized peritonitis [2.41 (95% CI, 1.27 to 4.61)], and SOFA score greater than 2 [6.14 (95% CI, 1.40 to 26.88)] were identified as independent risk factors for 28-day mortality. CONCLUSION: This multicentre observational study revealed that the time to surgical source control, patient severity and generalized peritonitis were identified as independent risk factors for increased hospital LOS and mortality in community-acquired IAI. Organisational strategies to reduce the time to surgical management of intra-abdominal infections should be further evaluated. STUDY REGISTRATION: ClinicalTrials.gov on 1 April 2018, NCT03544203.

Is it possible to improve prediction of outcome and blood requirements in the severely injured patients by defining categories of coagulopathy?

PURPOSE: It has been suggested to define the Trauma-induced coagulopathy (TIC) with a PTratio threshold of 1.20. We hypothesized that a more pragmatic classification would grade severity according to the PTratio (or corresponding ROTEM clotting time: EXTEM-CT), and that this would correlate better with the need for blood products (BP) and prognosis. METHODS: Retrospective analysis of prospectively collected data of 1076 severely injured patients admitted from 01/2011 to 12/2019 in a university hospital. To determine the number of TIC categories and the best PTratio or EXTEM-CT thresholds for mortality at 24-h, a modified Mazumdar approach was used. Multivariate regression analyses were done to describe the relationship between PTratio and ROTEM parameter subclasses with mortality. RESULTS: Three thresholds were, respectively, identified for PTratio (1.20, 1.90 and 3.00) and EXTEM-CT (90 s, 130 s, 200 s). The following categories were defined for PTratio: ≤ 1.20 (No TIC), 1.21-1.90 (Moderate TIC), 1.91-3.00 (severe TIC), > 3.00 (major TIC); and for EXTEM-CT: < 91 s (no TIC), 91-130 s (moderate TIC), 131-200 s (severe TIC) and > 200 s (major TIC). We observed that when the PTratio (or EXTEM-CT) increased, mortality and BP requirements increased. After multiple adjustments, we observed that each subclass of PTratio and EXTEM-CT was independently associated with mortality at 24-h. CONCLUSION: In this study, we have described a pragmatic classification of coagulopathy utilizing PTratio and EXTEM-CT where increasing severity was associated with prognosis and the amount of BP administered. This could allow clinicians to better predict the outcome and anticipate the need for blood products.

Complications and outcomes in 69 consecutive patients with floating hip.

BACKGROUND: Floating hip is a rare and potentially serious injury. The objective of this study was to evaluate our management strategy for patients with floating hip. HYPOTHESIS: A standardized strategy with specialised multidisciplinary management is associated with a low mortality rate. METHODS: Consecutive patients who had surgery to treat floating hip between January 2010 and December 2019 were included in this single-centre retrospective study. Epidemiological, clinical, and radiological data were collected and analysed. Patients were managed according to a standardised strategy adapted to the haemodynamic status and type of floating hip (type A, femoral and pelvic ring fractures; type B, femoral and acetabular fractures; and type C, femoral, acetabular, and pelvic ring fractures). The clinical outcome at last follow-up was determined by a telephone interview, based on the Majeed and Oxford scores, sports resumption, and work resumption. To assess the radiological outcomes, we applied Matta's criteria for the acetabulum and Tornetta's criteria for the pelvic ring. RESULTS: We included 69 patients with a mean age of 38.5 years. Among them, 39 (57%) had haemodynamic instability requiring embolisation (n=15, 22%) or multiple blood transfusions (n=24, 35%). Type A injuries predominated (n=57, 83%). The need for multiple blood transfusions was significantly associated with type C floating hip, underlining the risk of heavy bleeding with this injury. Two (3%) patients died. When management was complete, the reduction was anatomical or satisfactory for 76% (13/17) of the acetabula according to Matta's criteria (maximum residual displacement <3mm) and for 85% (56/66) of the pelvic rings according to Tornetta's criteria (maximum residual displacement <10mm). One or more complications occurred in 45 (65%) patients. After a mean follow-up of 5 years, the mean Oxford Hip Score in patients with acetabular fractures was 35.5 and the mean Majeed score in patients with pelvic ring fractures was 71.5. Only 30% of patients were able to resume physical activities at the former level and to return to their former professional activities. CONCLUSION: Type C floating hip, which combines fractures of the pelvic ring and acetabulum, carries a high risk of bleeding. Special attention should be directed to the reduction of pelvic ring fractures, to avoid malunion. Acetabular fractures that are complex in the Letournel classification carry a risk of imperfect reduction. The results of this study confirm the severity of these rare injuries and the need for specialised multidisciplinary management according to a standardised strategy that is appropriate for the haemodynamic status and type of floating hip (A, B, or C). LEVEL OF EVIDENCE: IV; retrospective study.

Traumatic brain injury in children with thoracic injury: clinical significance and impact on ventilatory management.

PURPOSE: This study aims to describe the epidemiology and management of chest trauma in our center, and to compare patterns of mechanical ventilation in patients with or without associated moderate-to-severe traumatic brain injury (TBI). METHODS: All children admitted to our level-1 trauma center from February 2012 to December 2018 following chest trauma were included in this retrospective study. RESULTS: A total of 75 patients with a median age of 11 [6-13] years, with thoracic injuries were included. Most patients also had extra-thoracic injuries (n = 71, 95%) and 59 (79%) had TBI. A total of 52 patients (69%) were admitted to intensive care and 31 (41%) were mechanically ventilated. In patients requiring mechanical ventilation, there was no difference in tidal volume or positive end-expiratory pressure in patients with moderate-to-severe TBI when compared with those with no-or-mild TBI. Only one patient developed Acute Respiratory Distress Syndrome. A total of 6 patients (8%) died and all had moderate-to-severe TBI. CONCLUSION: In this small retrospective series, most patients requiring mechanical ventilation following chest trauma had associated moderate-to-severe TBI. Mechanical ventilation to manage TBI does not seem to be associated with more acute respiratory distress syndrome occurrence.

Study protocol for a multicentre, 2×2 factorial, randomised, controlled trial evaluating the interest of intravenous iron and tranexamic acid to reduce blood transfusion in hip fracture patients (the HiFIT study).

INTRODUCTION: Blood transfusion and anaemia are frequent and are associated with poor outcomes in patients with hip fracture (HF). We hypothesised that preoperative intravenous iron and tranexamic acid (TXA) may reduce the transfusion rate in these patients. METHODS AND ANALYSIS: The HiFIT study is a multicentre, 2×2 factorial, randomised, double-blinded, controlled trial evaluating the effect of iron isomaltoside (IIM) (20 mg/kg) vs placebo and of TXA (intravenously at inclusion and topically during surgery) versus placebo on transfusion rate during hospitalisation, in patients undergoing emergency surgery for HF and having a preoperative haemoglobin between 95 and 130 g/L. 780 patients are expected. The primary endpoint is the proportion of patients receiving an allogenic blood transfusion of packed red blood cells from the day of surgery until hospital discharge (or until D30 if patient is still hospitalised). Enrolment started on March 2017 in 11 French hospitals. The study was stopped between July 2017 and August 2018 (because of investigation of serious AEs with IIM in Spain) and slowed down since March 2020 (COVID-19 crisis). The expected date of final follow-up is May 2022. Analyses of the intent-to-treat and per-protocol populations are planned. ETHICS AND DISSEMINATION: The HiFIT trial protocol has been approved by the Ethics Committee of Comité de Protection des Personnes Ouest II and the French authorities (ANSM). It will be carried out according to the principles of the Declaration of Helsinki and the Good Clinical Practice guidelines. The results will be disseminated through presentation at scientific conferences and publication in peer-reviewed journals. The HiFIT trial will be the largest study evaluating iron and TXA in patients with HF. TRIAL REGISTRATION NUMBER: clinicalTrials.gov identifier: NCT02972294; EudraCT Number 2016-003087-40.

Effect of under triage on early mortality after major pediatric trauma: a registry-based propensity score matching analysis.

BACKGROUND: Little is known about the effect of under triage on early mortality in trauma in a pediatric population. Our objective is to describe the effect of under triage on 24-h mortality after major pediatric trauma in a regional trauma system. METHODS: This cohort study was conducted from January 2009 to December 2017. Data were obtained from the registry of the Northern French Alps Trauma System. The network guidelines triage pediatric trauma patients according to an algorithm shared with adult patients. Under triage was defined by the number of pediatric trauma patients that required specialized trauma care transported to a non-level I pediatric trauma center on the total number of injured patients with critical resource use. The effect of under triage on 24-h mortality was assessed with inverse probability treatment weighting (IPTW) and a propensity score (Ps) matching analysis. RESULTS: A total of 1143 pediatric patients were included (mean [SD], age 10 [5] years), mainly after a blunt trauma (1130 [99%]). Of the children, 402 (35%) had an ISS higher than 15 and 547 (48%) required specialized trauma care. Nineteen (1.7%) patients died within 24 h. Under triage rate was 33% based on the need of specialized trauma care. Under triage of children requiring specialized trauma care increased the risk of death in IPTW (risk difference 6.0 [95% CI 1.3-10.7]) and Ps matching analyses (risk difference 3.1 [95% CI 0.8-5.4]). CONCLUSIONS: In a regional inclusive trauma system, under triage increased the risk of early death after pediatric major trauma.

Diagnostic performance of thromboelastometry in trauma-induced coagulopathy: a comparison between two level I trauma centres using two different devices.

PURPOSE: The implementation of a ROTEM®-based algorithm requires reliable thresholds to mirror a prothrombin time (PT) ratio > 1.2 and/or a fibrinogen concentration < 1.5 g l-1. Our goal was to compare the diagnostic performances of two devices (ROTEM® Sigma and Delta, IL Werfen, Munich, Germany) in two level-I trauma centres for the diagnostic of post-traumatic coagulopathy. METHODS: We conducted a retrospective analysis of two registries across two periods of time: from September 2014 to December 2015 in Lyon-Sud university trauma centre and from April 2016 to January 2018 in the Grenoble Alps Trauma Centre. Accuracies of EXTEM and FIBTEM assays to detect patients with coagulation disorders were tested for each device using receiver operating characteristic (ROC) analyses. RESULTS: Within the study period, 74 trauma patients in the Grenoble cohort and 75 trauma patients in the Lyon cohort had concomitant ROTEM® and standard coagulation testing on admission. No statistically significant difference was found between the two ROC curves for FIBTEM amplitude at 5 min (A5), FIBTEM maximum clot firmness, EXTEM clotting time (CT) and EXTEM A5 for ROTEM® Sigma and Delta to diagnose post-traumatic coagulation disorders. The best threshold for FIBTEM A5 to predict low fibrinogen concentration was 7 mm for each device. EXTEM CT thresholds to diagnose PT ratio > 1.2 were 78 s and 74 s for ROTEM® Sigma and Delta, respectively. CONCLUSIONS: These results suggest that ROTEM®-based algorithms may be transposed from one trauma centre to another independently of the setting and the ROTEM® device in use.

Effect of Prophylactic Embolization on Patients With Blunt Trauma at High Risk of Splenectomy: A Randomized Clinical Trial.

Importance: Splenic arterial embolization (SAE) improves the rate of spleen rescue, yet the advantage of prophylactic SAE (pSAE) compared with surveillance and then embolization only if necessary (SURV) for patients at high risk of spleen rupture remains controversial. Objective: To determine whether the 1-month spleen salvage rate is better after pSAE or SURV. Design, Setting, and Participants: In this randomized clinical trial conducted between February 6, 2014, and September 1, 2017, at 16 institutions in France, 133 patients with splenic trauma at high risk of rupture were randomized to undergo pSAE or SURV. All analyses were performed on a per-protocol basis, as well as an intention-to-treat analysis for specific events. Interventions: Prophylactic SAE, preferably using an arterial approach via the femoral artery, or SURV. Main Outcomes and Measures: The primary end point was an intact spleen or a spleen with at least 50% vascularized parenchyma detected on an arterial computed tomography scan at 1 month after trauma, assessed by senior radiologists masked to the treatment group. Secondary end points included splenectomy and pseudoaneurysm, secondary SAE after inclusion, complications, length of hospital stay, quality-of-life score, and length of time off work or studies during the 6-month follow-up. Results: A total of 140 patients were randomized, and 133 (105 men [78.9%]; median age, 30 years [interquartile range, 23-47 years]) were retained in the study. For the primary end point, data from 117 patients (57 who underwent pSAE and 60 who underwent SURV) could be analyzed. The number of patients with at least a 50% viable spleen detected on a computed tomography scan at month 1 was not significantly different between the pSAE and SURV groups (56 of 57 [98.2%] vs 56 of 60 [93.3%]; difference, 4.9%; 95% CI, -2.4% to 12.1%; P = .37). By the day 5 visit, there were significantly fewer splenic pseudoaneurysms among patients in the pSAE group than in the SURV group (1 of 65 [1.5%] vs 8 of 65 [12.3%]; difference, -10.8%; 95% CI, -19.3% to -2.1%; P = .03), significantly fewer secondary embolizations among patients in the pSAE group than in the SURV group (1 of 65 [1.5%] vs 19 of 65 [29.2%]; difference, -27.7%; 95% CI, -41.0% to -15.9%; P < .001), and no difference in the overall complication rate between the pSAE and SURV groups (19 of 65 [29.2%] vs 27 of 65 [41.5%]; difference, -12.3%; 95% CI, -28.3% to 4.4%; P = .14). Between the day 5 and month 1 visits, the overall complication rate was not significantly different between the pSAE and SURV groups (11 of 59 [18.6%] vs 12 of 63 [19.0%]; difference, -0.4%; 95% CI, -14.4% to 13.6%; P = .96). The median length of hospitalization was significantly shorter for patients in the pSAE group than for those in the SURV group (9 days [interquartile range, 6-14 days] vs 13 days [interquartile range, 9-17 days]; P = .002). Conclusions and Relevance: Among patients with splenic trauma at high risk of rupture, the 1-month spleen salvage rate was not statistically different between patients undergoing pSAE compared with those receiving SURV. In view of the high proportion of patients in the SURV group needing SAE, both strategies appear defendable. Trial Registration: ClinicalTrials.gov Identifier: NCT02021396.

Early management of severe abdominal trauma.

OBJECTIVE: To develop French guidelines on the management of patients with severe abdominal trauma. DESIGN: A consensus committee of 20 experts from the French Society of Anaesthesiology and Critical Care Medicine (Société française d'anesthésie et de réanimation, SFAR), the French Society of Emergency Medicine (Société française de médecine d'urgence, SFMU), the French Society of Urology (Société française d'urologie, SFU) and from the French Association of Surgery (Association française de chirurgie, AFC), the Val-de-Grâce School (École du Val-De-Grâce, EVG) and the Federation for Interventional Radiology (Fédération de radiologie interventionnelle, FRI-SFR) was convened. Declaration of all conflicts of interest (COI) policy by all participants was mandatory throughout the development of the guidelines. The entire guideline process was conducted independently of any industry funding. The authors were advised to follow the principles of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system for assessment of the available level of evidence with particular emphasis to avoid formulating strong recommendations in the absence of high level. Some recommendations were left ungraded. METHODS: The guidelines are divided in diagnostic and, therapeutic strategy and early surveillance. All questions were formulated according to Population, Intervention, Comparison, and Outcomes (PICO) format. The panel focused on three questions for diagnostic strategy: (1) What is the diagnostic performance of clinical signs to suggest abdominal injury in trauma patients? (2) Suspecting abdominal trauma, what is the diagnostic performance of prehospital FAST (Focused Abdominal Sonography for Trauma) to rule in abdominal injury and guide the prehospital triage of the patient? and (3) When suspecting abdominal trauma, does carrying out a contrast enhanced thoraco-abdominal CT scan allow identification of abdominal injuries and reduction of mortality? Four questions dealt with therapeutic strategy: (1) After severe abdominal trauma, does immediate laparotomy reduce morbidity and mortality? (2) Does a "damage control surgery" strategy decrease morbidity and mortality in patients with a severe abdominal trauma? (3) Does a laparoscopic approach in patients with abdominal trauma decrease mortality or morbidity? and (4) Does non-operative management of patients with abdominal trauma without bleeding reduce mortality and morbidity? Finally, one question was formulated regarding the early monitoring of these patients: In case of severe abdominal trauma, which kind of initial monitoring does allow to reduce the morbi-mortality? The analysis of the literature and the recommendations were conducted following the GRADE® methodology. RESULTS: The SFAR/SFMU Guideline panel provided 15 statements on early management of severe abdominal trauma. After three rounds of discussion and various amendments, a strong agreement was reached for 100% of recommendations. Of these recommendations, five have a high level of evidence (Grade 1±), six have a low level of evidence (Grade 2±) and four are expert judgments. Finally, no recommendation was provided for one question. CONCLUSIONS: Substantial agreement exists among experts regarding many strong recommendations for the best early management of severe abdominal trauma.

WSES consensus conference guidelines: monitoring and management of severe adult traumatic brain injury patients with polytrauma in the first 24 hours.

The acute phase management of patients with severe traumatic brain injury (TBI) and polytrauma represents a major challenge. Guidelines for the care of these complex patients are lacking, and worldwide variability in clinical practice has been documented in recent studies. Consequently, the World Society of Emergency Surgery (WSES) decided to organize an international consensus conference regarding the monitoring and management of severe adult TBI polytrauma patients during the first 24 hours after injury. A modified Delphi approach was adopted, with an agreement cut-off of 70%. Forty experts in this field (emergency surgeons, neurosurgeons, and intensivists) participated in the online consensus process. Sixteen recommendations were generated, with the aim of promoting rational care in this difficult setting.

Association of Prehospital Time to In-Hospital Trauma Mortality in a Physician-Staffed Emergency Medicine System.

Importance: The association between total prehospital time and mortality in physician-staffed trauma systems remains uncertain. Objective: To describe the association of total prehospital time and in-hospital mortality in prehospital, physician-staffed trauma systems in France, with the hypothesis that total prehospital time is associated with increased mortality. Design, Setting, and Participants: This cohort study was conducted from January 2009 to December 2016. Data for this study were derived from 2 distinct regional trauma registries in France (1 urban and 1 rural) that both have a physician-staffed emergency medical service. Consecutive adult trauma patients admitted to either of the regional trauma referral centers during the study period were included. Data analysis took place from March 2018 to September 2018. Main Outcomes and Measures: The association between death and prehospital time was assessed with a multivariable model adjusted with confounders. Total prehospital time was the primary exposure variable, recorded as the time from the arrival of the physician-led prehospital care team on scene to the arrival at the hospital. The main outcome of interest was all-cause in-hospital mortality. Results: A total of 10 216 patients were included (mean [SD] age, 41 [18] years; 7937 men [78.3%]) affected by predominantly nonpenetrating injuries (9265 [91.5%]), with a mean (SD) Injury Severity Score of 17 (14) points. Of the patients, 6737 (66.5%) had at least 1 body region with an Abbreviated Injury Scale score of 3 or more. A total of 1259 patients (12.4%) presented in shock (with systolic pressure <90 mm Hg) and 2724 (26.9%) with severe head injury (Abbreviated Injury Scale score ≥3 points). On unadjusted analysis, increasing prehospital times (in 30-minute categories) were associated with a markedly and constant increase in the risk of in-hospital death. The odds of death increased by 9% for each 10-minute increase in prehospital time (odds ratio, 1.09 [95% CI, 1.07-1.11]) and after adjustment by 4% (odds ratio, 1.04 [95% CI, 1.01-1.07]). Conclusions and Relevance: In this study, an increase in total prehospital time was associated with increasing in-hospital all-cause mortality in trauma patients at a physician-staffed emergency medical system, after adjustment for case complexity. Prehospital time is a management objective in analogy to physiological targets. These findings plead for a further streamlining of prehospital trauma care and the need to define the optimal intervention-to-time ratio.
