Introduction Non-operative management is currently the preferred approach in blunt liver trauma, including high grade liver lesions. However, hemodynamic instability imposes the need for an emergency laparotomy, with a perihepatic packing (PHP) to control liver bleeding in most cases. Our retrospective study aimed to assess the outcomes of liver trauma patients who underwent a shortened PHP. Methods All consecutive patients who underwent PHP for blunt liver trauma from 1998 to 2019 in our Level I trauma center were included in the study. Unstable patients with severe liver trauma were transferred to the operating room without any delay, and a collective decision was made to perform abbreviated laparotomy to pack the liver. Demographics, perioperative data, postoperative outcomes, and mortality were retrospectively collected, and survivors and deceased patients were compared with a paired t-test. Results Fifty-nine patients of 206 patients admitted with severe liver injuries were treated with shortened PHP. Thirty-four (57.6%) patients died, including 26 (76.5%) within the first 24 h. Twelve (20.3%) patients had a selective hepatic embolization and eight (13.6%) had an extrahepatic embolization. Forty-eight patients had an extra abdominal associated injury. This was not a predictive factor of mortality. The removal of packing was performed in 24 patients within 72 h after laparotomy, with an 80% survival rate in these patients. Conclusion Shortened PHP is an effective strategy for controlling liver bleeding in severe hepatic trauma. The mortality rate of these patients is high, but after the removal of packing, the survival is good.

BackgroundManagement of bowel traumatic injuries is a challenge. Although anastomotic or suture leak remains a feared complication, preserving bowel continuity is increasingly the preferred strategy. The aim of this study was to evaluate the outcomes of such a strategy.MethodsAll included patients underwent surgery for bowel traumatic injuries at a high volume trauma center between 2007 and 2017. Postoperative course was analyzed for abdominal complications, morbidity and mortality.ResultsAmong 133 patients, 78% had small bowel injuries and 47% had colon injuries. 87% of small bowel injuries and 81% of colon injuries were treated with primary repair or anastomosis, with no difference in treatment according to injury site (p = 0.381). Mortality was 8%. Severe overall morbidity was 32%, and abdominal complications occurred in 32% of patients. Risk factors for severe overall morbidity were stoma creation (p = 0.036), heavy vascular expansion (p = 0.005) and a long delay before surgery (p = 0.023). Fistula rate was 2.2%; all leaks occurred after repairing small bowel wounds.ConclusionPrimary repair of bowel injuries should be the preferred option in trauma patient, regardless of the site—small bowel or colon—of the injury. Stoma creation is an important factor for postoperative morbidity, which should be weighed against the risk of an intestinal suture or anastomosis.

International audience; Objective: Identify issues that are important to severe trauma survivors up to 3 years after the trauma. Background: Severe trauma is the first cause of disability-adjusted life years worldwide, yet most attention has focused on acute care and the impact on long-term health is poorly evaluated. Method: We conducted a large-scale qualitative study based on semi-structured phone interviews. Qualitative research methods involve the systematic collection, organization, and interpretation of conversations or textual data with patients to explore the meaning of a phenomenon experienced by individuals themselves. We randomly selected severe trauma survivors (abbreviated injury score ≥3 in at least 1 body region) who were receiving care in 6 urban academic level-I trauma centers in France between March 2015 and March 2018. We conducted double independent thematic analysis. Issues reported by patients were grouped into overarching domains by a panel of 5 experts in trauma care. Point of data saturation was estimated with a mathematical model. Results: We included 340 participants from 3 months to 3 years after the trauma [median age: 41 years (Q1-Q3 24-54), median injury severity score: 17 (Q1-Q3 11-22)].We identified 97 common issues that we grouped into 5 overarching domains: Body and neurological issues (29 issues elicited by 277 participants), biographical disruption (23 issues, 210 participants), psychological and personality issues (21 issues, 147 participants), burden of treatment (14 issues, 145 participants), and altered relationships (10 issues, 87 participants). Time elapsed because the trauma, injury location, or in-hospital trauma severity did not affect the distribution of these domains across participants' answers. Conclusions: This qualitative study explored trauma survivors' experiences of the long-term effect of their injury and allowed for identifying a set of issues that they consider important, including dimensions that seem overlooked in trauma research. Our findings confirm that trauma is a chronic medical condition that demands new approaches to post-discharge and longterm care.

New finding What is the central question of this study? Transition to supine posture induces an inspiratory load associated with cortical activation in awake healthy subjects. Some obstructive sleep apnoea patients exhibit this cortical activity in the sitting position contributing to the arousal-dependent compensation of their upper airway abnormalities. Does a transition to the supine posture in awake obstructive sleep apnoea patients increase this cortical activity? What is the main finding and its importance? The transition to supine posture induces a reduction in the cortical activity despite evidence of an increase in genioglossus activity, suggesting that genioglossus activation is not driven by cortical activity. Abstract The anatomy and mechanical properties of the upper airway (UA) depend on posture. Lying in a supine position causes cephalad fluid shift to the neck, thus narrowing the UA and predisposing the individual to obstructive sleep apnoea (OSA). Increased UA dilator muscle activity during wakefulness prevents the UA collapse but the underlying mechanism has not yet been elucidated. In the sitting position during wakefulness, some OSA patients exhibit preinspiratory cortical activity (preinspiratory potential, PIP) probably related to UA abnormalities. The aim of this study was to investigate changes in the preinspiratory cortical activity and UA dilator muscle in OSA patients during postural challenge. An electroencephalogram was used to detect PIP, and the genioglossus electromyographic activity and ventilation were analysed in 17 awake, male OSA patients while they were sitting, just after lying down, and then in response to leg positive pressure to enhance cephalad fluid shift. The prevalence of PIP decreased from 53% (sitting) to 12% (supine) (P = 0.002) in association with increased genioglossus activity (tonic from median (25th, 75th centiles) 2.3 (1.8, 2.8)% to 3.6 (1.7, 5.0)% of voluntary deglutition, P = 0.019; phasic from 2.3 (1.9, 2.8)% to 3.7 (2.0, 6.1)%, P = 0.024), and with increased transcutaneous carbon dioxide pressure (from 43.0 (42.4, 44.2) to 44.6 (43.5, 45.2) mmHg). No change was observed during leg-positive-pressure application. Moving from the sitting position to the supine position reduces respiratory-related premotor cortical activity in awake OSA patients. The concomitant increase in genioglossus activity, therefore, is not driven by cortical respiratory activity.

Background Reports published directly after terrorist mass casualty incidents frequently fail to capture difficulties that may have been encountered. An anonymised consensus-based platform may enable discussion and collaboration on the challenges faced. Our aim was to identify where to focus improvement for future responses. Methods We conducted a mixed methods study by email of clinicians' experiences of leading during terrorist mass casualty incidents. An initial survey identified features that worked well, or failed to, during terrorist mass casualty incidents plus ongoing challenges and changes that were implemented as a result. A follow-up, quantitative survey measured agreement between responses within each of the themes using a Likert scale. Results Thirty-three participants responded from 22 hospitals that had received casualties from a terrorist incident, representing 17 cities in low-middle, middle and high income countries. The first survey identified themes of sufficient (sometimes abundant) human resource, although coordination of staff was a challenge. Difficulties highlighted were communication, security, and management of blast injuries. The most frequently implemented changes were education on specific injuries, revising future plans and preparatory exercises. Persisting challenges were lack of time allocated to training and psychological well-being. The follow-up survey recorded highest agreement amongst correspondents on the need for re-triage at hospital (90% agreement), coordination roles (85% agreement), flexibility (100% agreement), and large-scale exercises (95% agreement). Conclusion This survey collates international experience gained from clinicians managing terrorist mass casualty incidents. The organisation of human response, rather than consumption of physical supplies, emerged as the main finding. NHSH Clinical Effectiveness Unit project registration number: 2020/21–036.

Backround Triage is key in the management of mass casualty incidents. Objective The objective of this study was to assess the prehospital triage performed during the 2015 Paris area terrorist attack. Design setting and participant This was a retrospective cohort study that included all casualties of the attacks on 13 November 2015 in Paris area, France, that were admitted alive at the hospital within the first 24 h after the events. Patients were triaged as absolute emergency or relative emergency by a prehospital physician or nurse. This triage was then compared to the one of an expert panel that had retrospectively access to all prehospital and hospital files. Outcomes measures and analysis The primary endpoints were the rate of overtriage and undertriage, defined as number of patients misclassified in one triage category, divided by the total number of patients in this triage category. Main result Among 337 casualties admitted to the hospital, 262 (78%) were triaged during prehospital care, with, respectively, 74 (28%) and 188 (72%) as absolute and relative emergencies. Among these casualties, the expert panel classified 96 (37%) patients as absolute emergencies and 166 (63%) as relative emergency. The rate of undertriage and overtriage was 36% [95% confidence interval (CI), 27-47%] and 8% (95% CI, 4-13%), respectively. Among undertriaged casualties, 8 (23%) were considered as being severely undertriaged. Among overtriaged casualties, 10 (77%) were considered as being severely overtriaged. Conclusion A simple prehospital triage for trauma casualties during the 13 November terrorist attack in Paris could have been performed triaged in 78% of casualties that were admitted to the hospital, with a 36% rate of undertriage and 8% of overtriage. Qualitative analysis of undertriage and overtriage indicate some possibilities for further improvement.

We aimed to assess the incidence and the risk factors for secondary wound infections associated to high-energy ammunition injuries (HEAI) in the cohort of civilian casualties from the 2015 terrorist attacks in Paris.This retrospective multi-centric study included casualties presenting at least one HEAI who underwent surgery during the first 48 h following hospital admission. HEAI-associated infection was defined as a wound infection occurring within the initial 30 days following trauma. Risk factors were assessed using univariate and multivariate analysis.Among the 200 included victims, the rate of infected wounds was 11.5%. The median time between admission and the surgical revision for secondary wound infection was 11 days [IQR 9-20]. No patient died from an infectious cause. Infections were polymicrobial in 44% of the cases. The major risk factors for secondary wound infection were ISS (p 0.001), SAPS II (p 0.001), MGAP (p 0.001), haemorrhagic shock (p = 0.003), use of vasopressors (p 0.001), blood transfusion (p 0.001), abdominal penetrating trauma (p = 0.003), open fracture (p = 0.01), vascular injury (p = 0.001), duration of surgery (p = 0.009), presence of surgical material (p = 0.01). In the multivariate analysis, the SAPS II score (OR 1.07 [1.014-1.182], p = 0.019) and the duration of surgery (OR 1.005 [1.000-1.012], p = 0.041) were the only risk factors identified.We report an 11.5% rate of secondary wound infection following high-energy ammunition injuries. Risk factors were an immediately severe condition and a prolonged surgery.

International audience; Background This study provides a detailed imaging assessment in a large series of patients infected with coronavirus disease 2019 (COVID-19) and presenting with neurologic manifestations. Purpose To review the MRI findings associated with acute neurologic manifestations in patients with COVID-19. Materials and Methods This was a cross-sectional study conducted between March 23 and May 7, 2020, at the Pitié-Salpêtrière Hospital, a reference center for COVID-19 in the Paris area. Adult patients were included if they had a diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection with acute neurologic manifestations and referral for brain MRI. Patients with a prior history of neurologic disease were excluded. The characteristics and frequency of different MRI features were investigated. The findings were analyzed separately in patients in intensive care units (ICUs) and other departments (non-ICU). Results During the inclusion period, 1176 patients suspected of having COVID-19 were hospitalized. Of 308 patients with acute neurologic symptoms, 73 met the inclusion criteria and were included (23.7%): thirty-five patients were in the ICU (47.9%) and 38 were not (52.1%). The mean age was 58.5 years ± 15.6 [standard deviation], with a male predominance (65.8% vs 34.2%). Forty-three patients had abnormal MRI findings 2-4 weeks after symptom onset (58.9%), including 17 with acute ischemic infarct (23.3%), one with a deep venous thrombosis (1.4%), eight with multiple microhemorrhages (11.3%), 22 with perfusion abnormalities (47.7%), and three with restricted diffusion foci within the corpus callosum consistent with cytotoxic lesions of the corpus callosum (4.1%). Multifocal white matter-enhancing lesions were seen in four patients in the ICU (5%). Basal ganglia abnormalities were seen in four other patients (5%). Cerebrospinal fluid analyses were negative for SARS-CoV-2 in all patients tested (n = 39). Conclusion In addition to cerebrovascular lesions, perfusion abnormalities, cytotoxic lesions of the corpus callosum, and intensive care unit-related complications, we identified two patterns including white matter-enhancing lesions and basal ganglia abnormalities that could be related to severe acute respiratory syndrome coronavirus 2 infection. © RSNA, 2020 Online supplemental material is available for this article.

Preliminary clinical data indicate that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is associated with neurological and neuropsychiatric illness. Responding to this, a weekly virtual coronavirus disease 19 (COVID-19) neurology multi-disciplinary meeting was established at the National Hospital, Queen Square, in early March 2020 in order to discuss and begin to understand neurological presentations in patients with suspected COVID-19-related neurological disorders. Detailed clinical and paraclinical data were collected from cases where the diagnosis of COVID-19 was confirmed through RNA PCR, or where the diagnosis was probable/possible according to World Health Organization criteria. Of 43 patients, 29 were SARS-CoV-2 PCR positive and definite, eight probable and six possible. Five major categories emerged: (i) encephalopathies (n = 10) with delirium/psychosis and no distinct MRI or CSF abnormalities, and with 9/10 making a full or partial recovery with supportive care only; (ii) inflammatory CNS syndromes (n = 12) including encephalitis (n = 2, para- or post-infectious), acute disseminated encephalomyelitis (n = 9), with haemorrhage in five, necrosis in one, and myelitis in two, and isolated myelitis (n = 1). Of these, 10 were treated with corticosteroids, and three of these patients also received intravenous immunoglobulin; one made a full recovery, 10 of 12 made a partial recovery, and one patient died; (iii) ischaemic strokes (n = 8) associated with a pro-thrombotic state (four with pulmonary thromboembolism), one of whom died; (iv) peripheral neurological disorders (n = 8), seven with Guillain-Barré syndrome, one with brachial plexopathy, six of eight making a partial and ongoing recovery; and (v) five patients with miscellaneous central disorders who did not fit these categories. SARS-CoV-2 infection is associated with a wide spectrum of neurological syndromes affecting the whole neuraxis, including the cerebral vasculature and, in some cases, responding to immunotherapies. The high incidence of acute disseminated encephalomyelitis, particularly with haemorrhagic change, is striking. This complication was not related to the severity of the respiratory COVID-19 disease. Early recognition, investigation and management of COVID-19-related neurological disease is challenging. Further clinical, neuroradiological, biomarker and neuropathological studies are essential to determine the underlying pathobiological mechanisms, which will guide treatment. Longitudinal follow-up studies will be necessary to ascertain the long-term neurological and neuropsychological consequences of this pandemic.

SARS-CoV-2 can cause severe pneumonia requiring invasive mechanical ventilation [2], in the context of atypical acute respiratory distress syndrome (ARDS) [3]. The magnitude of the epidemic places an unprecedented pressure on intensive care units (ICU), making avoidance of intubation a critical issue., COVID-19 pneumonia can be life-threatening. Given the unprecedented burden place on ICU resources by the epidemic, avoiding intubation is a major issue. This study suggests that CPAP can achieve this objective.

Background The value of intravenous oxycodone compared to morphine remains controversial. The purpose of this trial was to compare opioid-related adverse events (ORAES) of intravenous oxycodone and morphine after total hip arthroplasty. Methods Patients scheduled for total hip arthroplasty were enrolled in this study of postoperative pain treatment with intravenous oxycodone or intravenous morphine (ratio 1:1). After surgery, patients received similar drug regimens for titration in the postoperative care unit followed by intravenous patient-controlled analgesia (PCA). The primary outcome was the number of patients with ≥1 ORAEs within the first 24 hours defined as either nausea, vomiting, respiratory depression, pruritus, urinary retention requiring evacuation, allergy, hallucinations. Secondary outcomes included pain scores and opioid consumption. Results The analysis included 238 patients with similar characteristics. There were 55 patients with at least one ORAEs in the oxycodone group versus 46 in the morphine group: 48% vs 40%, p=0.19; relative risk= 1.22 (0.91:1.63). Intravenous oxycodone vs intravenous morphine requirements were respectively (median, IQR): 6 (0-11) versus 8 (0-12) mg (p=0.06) for titration, 15 (8-26) vs 8 (5-16) mg (p=0.001) for PCA, and 22 (12-37) mg vs 19 (11-28) mg for cumulated intravenous consumption (p=0.048). During the first 24hr, there was no difference in secondary outcomes (oxycodone versus morphine, respectively, in %): nausea (15 vs 13), vomiting (5 vs 5), urinary retention (20 vs 12) or pain scores. Conclusion This study demonstrates that IV oxycodone did not significantly reduce ORAEs within the first 24 hours compared to similar ratio of IV morphine.

Wearable EEG systems have become accessible to researchers and clinicians over the last decade, thus requiring neurotechnology companies to seek for outstanding EEG signal quality. Here, we show that the melomind™ headset equipped with dry electrodes (myBrain Technologies, Paris, France) allows the recording of reliable electro-cortical dynamics as compared to a wet-based standard-EEG system (actiCAP, Brain Products GmbH, Gilching, Germany). EEGs were acquired simultaneously from the two systems while thirteen subjects underwent a visual oddball, a steady-state visually-evoked potentials (SSVEPs) and two resting-state (RS) tasks. RS were acquired with eyes-closed and eyes-open (2 minutes each) and repeated twice (before and after the cognitive tasks). During the oddball task, participants responded on a gamepad when a target-stimulus was displayed. In the SSVEPs, visual responses were elicited at 15 and 20 Hz through a series of 15-second stimuli presented 5 times each. The power of theta- [4-8 Hz], alpha- [8-13 Hz], and beta- [13-30 Hz] band was extracted from the two RS. The signal-to-noise-ratio in the 15 (± 1) and 20 (± 1) Hz range was computed from the SSVEPs. The shape of the N2/P300 complex was analysed from the oddball task. Strong correlations resulted between the parameters obtained from the two EEG systems (0.53 < Pearson’s r < 0.97). Bland and Altman analysis revealed small dissimilarities between the two systems, with values laying in the 95% confidence interval in all the tasks. Our results demonstrate that the melomind™ is an affordable solution to reliably assess humans’ electro-cortical dynamics at-rest and during cognitive tasks, thus paving the way to its use in neuroscience studies and brain-computer interfaces.

Objective Hemorrhage is the leading cause of death after terrorist attack, and the immediacy of labile blood product (LBP) administration has a decisive impact on patients' outcome. The main objective of this study was to evaluate the transfusion patterns of the Paris terrorist attack victims, November 13, 2015. Methods We performed a retrospective analysis including all casualties admitted to hospital, aiming to describe the transfusion patterns from admission to the first week after the attack. Results Sixty-eight of 337 admitted patients were transfused. More than three quarters of blood products were consumed in the initial phase (until November 14, 11:59 PM), where 282 packed red blood cell (pRBC) units were transfused along with 201 plasma and 25 platelet units, to 55 patients (16% of casualties). Almost 40% of these LBPs (134 pRBC, 73 plasma, 8 platelet units) were transfused within the first 6 hours after the attack. These early transfusions were massive transfusion (MT) for 20 (6%) of 337 patients, and the average plasma/red blood cell ratio was 0.8 for MT patients who received 366 (72%) of 508 LBPs.The median time from admission to pRBC transfusion was 57 (25-108) minutes and 208 (52-430) minutes for MT and non-MT patients, respectively. These same time intervals were 119 (66-202) minutes and 222 (87-381) minutes for plasma and 225 (131-289) minutes and 198 (167-230) minutes for platelets. Conclusion Our data suggest that improving transfusion procedures in mass casualty setting should rely more on shortening the time to bring LBP to the bedside than in increasing the stockpile. Level of evidence Epidemiological study, Therapeutic IV.

IntroductionPreventing in-flight hypoxia in pilots is typically achieved by wearing oxygen masks. These masks must be as comfortable as possible to allow prolonged and repeated use. The consequences of mask-induced facial contact pressure have been extensively studied, but little is known about mask-induced breathing discomfort. Because breathlessness is a strong distractor and engages cerebral resources, it could negatively impact flying performances.MethodsSeventeen volunteers (age 20–32) rated respiratory discomfort while breathing with no mask and with two models of quick-donning full-face crew oxygen masks with regulators (mask A, mask B). Electroencephalographic recordings were performed to detect a putative respiratory-related cortical activation in response to inspiratory constraint (experiment 1, n=10). Oxygen consumption was measured using indirect calorimetry (experiment 2, n=10).ResultsWith mask B, mild respiratory discomfort was reported significantly more frequently than with no mask or mask A (experiment 1: median respiratory discomfort on visual analogue scale 0.9 cm (0.5–1.4), experiment 1; experiment 2: 2 cm (1.7–2.9)). Respiratory-related cortical activation was present in 1/10 subjects with no mask, 1/10 with mask A and 6/10 with mask B (significantly more frequently with mask B). Breathing pattern, sigh frequency and oxygen consumption were not different.ConclusionsIn a laboratory setting, breathing through high-end aeronautical full-face crew oxygen masks can induce mild breathing discomfort and activate respiratory-related cortical networks. Whether or not this can occur in real-life conditions and have operational consequences remains to be investigated. Meanwhile, respiratory psychometric and neuroergonomic approaches could be worth integrating to masks development and evaluation processes.

Background Haemorrhagic shock is the leading cause of early preventable death in severe trauma. Delayed treatment is a recognized prognostic factor that can be prevented by efficient organization of care. This study aimed to develop and validate Red Flag, a binary alert identifying blunt trauma patients with high risk of severe haemorrhage (SH), to be used by the pre-hospital trauma team in order to trigger an adequate intra-hospital standardized haemorrhage control response: massive transfusion protocol and/or immediate haemostatic procedures. Methods A multicentre retrospective study of prospectively collected data from a trauma registry (Traumabase®) was performed. SH was defined as: packed red blood cell (RBC) transfusion in the trauma room, or transfusion ≥ 4 RBC in the first 6 h, or lactate ≥ 5 mmol/L, or immediate haemostatic surgery, or interventional radiology and/or death of haemorrhagic shock. Pre-hospital characteristics were selected using a multiple logistic regression model in a derivation cohort to develop a Red Flag binary alert whose performances were confirmed in a validation cohort. Results Among the 3675 patients of the derivation cohort, 672 (18%) had SH. The final prediction model included five pre-hospital variables: Shock Index ≥ 1, mean arterial blood pressure ≤ 70 mmHg, point of care haemoglobin ≤ 13 g/dl, unstable pelvis and pre-hospital intubation. The Red Flag alert was triggered by the presence of any combination of at least two criteria. Its predictive performances were sensitivity 75% (72–79%), specificity 79% (77–80%) and area under the receiver operating characteristic curve 0.83 (0.81–0.84) in the derivation cohort, and were not significantly different in the independent validation cohort of 2999 patients. Conclusion The Red Flag alert developed and validated in this study has high performance to accurately predict or exclude SH.

Objectives To compare the association between a restrictive transfusion strategy and cardiovascular complications during hospitalization for hip fracture with the association between a liberal transfusion strategy and cardiovascular complications, accounting for all transfusions from the emergency department to postacute rehabilitation settings. Design Retrospective study. Setting Perioperative geriatric care unit. Participants All individuals aged 70 and older admitted to the emergency department for hip fracture and hospitalized in our perioperative geriatric care unit (N=667; n=193 in the liberal transfusion group, n=474 in the restrictive transfusion group) from July 2009 to April 2016. Intervention A restrictive transfusion strategy (hemoglobin level threshold ≥8 g/dL or symptoms) used from January 2012 to April 2016 was compared with the liberal transfusion strategy (hemoglobin level threshold ≥10 g/dL) used from July 2009 to December 2011. Measurements Primary endpoint was in‐hospital acute cardiovascular complications (heart failure, myocardial infarction, atrial fibrillation or stroke). Results The change to a restrictive transfusion strategy was associated with fewer acute cardiovascular complications (odds ratio=0.45, 95% confidence interval (CI)=0.31–0.67, p

BACKGROUND Use of the internet as an information search tool has increased dramatically. Our study assessed preoperative use of the internet by patients to search for information regarding anaesthesia, surgery, pain or outcomes. OBJECTIVE(S) The aim of this study was to test whether patients used the internet prior to surgery and what kinds of information they looked for (anaesthetic technique, pain, adverse events, outcomes and surgery). Correlation between patient age and information sought about surgery from the internet was also explored. DESIGN A prospective multicentre observational study. SETTING In total, 14 French private and public institutions from May 2015 to January 2016. PATIENTS In total, 3161 adult patients scheduled for elective surgery under regional or general anaesthesia. INTERVENTION(S) An anonymous questionnaire was presented to adult patients scheduled for elective surgery under regional or general anaesthesia for completion before the first meeting with the anaesthesiologist. The investigator at each centre completed specific items that the patient could not complete. MAIN OUTCOME MEASURES We defined the primary endpoint as the number of patients who searched for information about their anaesthesia or surgery on the internet by the time of the their preanaesthetic consultation. RESULTS Of the 3234 questionnaires distributed, responses were received from 3161 patients. Within this respondent sample, 1304 (45%) were professionally active and 1664 (59%) used the internet at least once per day. Among 3098 (98%) patients who answered the question concerning the primary endpoint, 1506 (48%) had searched the internet for information about their health. In total, 784 (25%) used the internet to find information about their surgery and 113 (3.5%) looked for specific information about anaesthesia. Of the 3161, 52% reported difficulty searching for appropriate information about anaesthesia on the internet. 'Daily use of the web' [odds ratio (OR) 2.0; (95% CI: 1.65 to 2.55) P

OBJECTIVES The Paris terrorist attacks on 13 November 2015 caused 482 casualties, including 130 deaths and 352 wounded. Facing these multisite terrorist attacks, Parisian public and military hospitals simultaneously managed numerous patients with penetrating thoracic injuries. The aim of this study was to analyse this cohort, the injury patterns, and assess the results of this mobilization. METHODS The clinical records of all patients admitted to Parisian public and military hospitals with a penetrating thoracic injury related to the Paris 13 November terrorist attacks were reviewed. RESULTS The study group included 25 patients (7% of the casualties) with a mean age of 34 ± 8 years and a majority of gunshot wounds ( n = 20, 80%). Most patients presented with severe thoracic injury (Abbreviated Injury Score Thorax 3.3 ± 1.2), and also associated non-thoracic injuries in 21 cases (84%). The mean Injury Severity Score was 26.8 ± 9.4. Eight patients (32%) were managed with chest tube insertion and 17 (68%) required thoracic surgery. Lung resection, diaphragmatic repair, and lung suture were performed in 6 (36%), 6 (35%), and 5 cases (29%), respectively. Extra-thoracic surgical procedures were performed in 16 patients, mostly for injuries to the extremities. Postoperative mortality was 12% ( n = 3) and postoperative morbidity was 60% ( n = 15). CONCLUSIONS The coordination of Parisian military and civilian hospitals allowed the surgical management of 25 patients. The mortality is high but consistent with what has been reported in previous series. The current times expose us to the threat of new terrorist attacks and require that the medical community be prepared.

Background Initial blood lactate and base deficit have been shown to be prognostic biomarkers in trauma, but their respective performances have not been compared. Methods Blood lactate levels and base deficit were measured at admission in trauma patients in three level 1 trauma centers. This was a retrospective analysis of prospectively acquired data. The association of initial blood lactate and base deficit with mortality was tested using receiver operating characteristics curve, logistic regression using triage scores (Revised Trauma Score and Mechanism Glasgow scale and Arterial Pressure score), and Trauma Related Injury Severity Score as a reference standard. The authors also used a reclassification method. Results The authors evaluated 1,075 trauma patients (mean age, 39 ± 18 yr, with 90% blunt and 10% penetrating injuries and a mortality of 13%). At admission, blood lactate was elevated in 425 (39%) patients and base deficit was elevated in 725 (67%) patients. Blood lactate was correlated with base deficit (R2 = 0.54; P < 0.001). Using logistic regression, blood lactate was a better predictor of death than base deficit when considering its additional predictive value to triage scores and Trauma Related Injury Severity Score. This result was confirmed using a reclassification method but only in the subgroup of normotensive patients (n = 745). Conclusions Initial blood lactate should be preferred to base deficit as a biologic variable in scoring systems built to assess the initial severity of trauma patients.

Dyspnoea is frequent and distressing in patients receiving mechanical ventilation, but it is often not properly evaluated by caregivers. Electroencephalographic signatures of dyspnoea have been identified experimentally in healthy subjects. We hypothesized that adjusting ventilator settings to relieve dyspnoea in MV patients would induce EEG changes. This was a first-of-its-kind observational study in a convenience population of 12 dyspnoeic, mechanically ventilated patients for whom a decision to adjust the ventilator settings was taken by the physician in charge (adjustments of pressure support, slope, or trigger). Pre- and post-ventilator adjustment electroencephalogram recordings were processed using covariance matrix statistical classifiers and pre-inspiratory potentials. The pre-ventilator adjustment median dyspnoea visual analogue scale was 3.0 (interquartile range: 2.5–4.0; minimum-maximum: 1–5) and decreased by (median) 3.0 post-ventilator adjustment. Statistical classifiers adequately detected electroencephalographic changes in 8 cases (area under the curve ≥0.7). Previously present pre-inspiratory potentials disappeared in 7 cases post-ventilator adjustment. Dyspnoea improvement was consistent with electroencephalographic changes in 9 cases. Adjusting ventilator settings to relieve dyspnoea produced detectable changes in brain activity. This paves the way for studies aimed at determining whether monitoring respiratory-related electroencephalographic activity can improve outcomes in critically ill patients under mechanical ventilation.

Introduction Prevalence and tobacco-related perioperative complications have been largely reported. The impact of vaping (e-cigarette use) on the perioperative period has been rarely evaluated. The purpose of this multicentre cross-sectional survey was to assess the prevalence of vaping and behaviour of patients undergoing elective surgery. Methods After institutional review board committee and patient approvals, patients (aged ≥18 years) scheduled for elective non-cardiac surgery in six French hospitals were assessed preoperatively. Demographic characteristics, and information on vaping, smoking or dual-use status and consumption were reported. Results In six centres, 1712 eligible patients were approached and 1664 patients were included in this study from June 2016 to January 2017. Of these, 62 patients used e-cigarettes in the preoperative period (3%; 95% CI: 2–4), including 24 exclusive e-cigarette users (1%; 95% CI: 1–2), 38 dual-users (2%; 95% CI: 2–3) and 365 smokers (22%; 95% CI: 20–24). Vapers were older than smokers (53 vs 47 years old; p=0.01). During the preoperative period, 12 patients (1%) reported vaping the morning of surgery. Conclusions In the preoperative period, vaping was ten-fold less prevalent than smoking. Although the clinical relevance may be weak, further research is needed to explore the real impact of vaping on patients’ outcomes and to elaborate on clinical recommendations.

Over the last 20 years, numerous studies have fairly consistently reported an improvement in the prognosis of patients with severe trauma after the establishment of a trauma network. These systems can be either exclusive, in which all patients are referred only to a small number of specifically designated centres that meet strict criteria, or inclusive, in which patients may be referred to any hospital of a particular area according to capacity, which is observed in France. Hospitals are classified (level 1 to level 3) according to their technical facilities and the number of patients admitted for severe trauma, knowing that studies have also shown an improvement of the outcome for the most severely injured patients (haemorrhagic shock, severe head trauma), in hospitals with the greatest technical facilities and the most important activity. The triage of the patients to a suitable centre must be done after careful prehospital evaluation, which is made on clinical criteria (mechanism, injury, medical history), measurement of vital signs, calculation of scores (RTS, MGAP) or based on classifications. According to this assessment, the patients will then be triaged to a centre that has the capacity for the optimal and definitive management of these injuries. The goal is then to avoid under triage which is synonymous of retransfer, loss of time, and probably also prognosis worsening, and to avoid over triage that may induce an inadequate use of resources, activity overload and cost increase. Thus, it seems essential to develop trauma networks to improve mortality and morbidity of patients that undergone a severe injury. These trauma networks will then have to be evaluated and a register set up.

Introduction In elderly patients, goal-directed haemodynamic therapy (GDHT), depth of anaesthesia monitoring and lung-protective ventilation have been shown to improve postoperative outcomes. The aim of this study was to evaluate current practices concerning strategies of anaesthesia optimisation in patients aged ≥ 75 years. Patients and methods A multicentre observational study was performed from February to May 2015 in 23 French academic centres. On 30 consecutive days in each centre, patients ≥ 75 years with at least one major comorbidity undergoing elective or emergency procedures (femoral-neck fractures surgery, intraperitoneal abdominal surgery or vascular surgery) were included. Patient characteristics and data related to GHDT, management of hypotension, monitoring of temperature and depth of anaesthesia, lung ventilation, point of care haemoglobin testing were collected. Results In total, 807 patients were included. Only 2% of patients [95% CI: 1–3] received GHDT in full accordance with guidelines. Depth of anaesthesia monitoring was largely performed (53% [95% CI: 50–56]). The multifaceted strategy of lung-protective ventilation combining low tidal volumes (6–8 mL/kg), PEEP of 5–8 cm cmH2O, and repeated recruitment manoeuvres, was performed in only 4% [95% CI: 3–5] of patients. A centre effect was a major determinant of variation concerning implementation of these strategies. Discussion In patients’ ≥ 75 years, strategies of anaesthesia optimisation are not in accordance with eligible guidelines. Implementation of these techniques varies independently of factors related to the patient or the type of surgery and may be dependent on the generated constraints.

International audience; Background: Arterial injury secondary to acute knee dislocation (KD) is a rare but devastative complication. The aim of this study is to evaluate functional sequelae and factors of poor prognosis.Methods: A retrospective monocentric series of consecutive KD with acute ischemia by popliteal artery injury was analyzed between 2005 and 2017. The main outcome was the amputation rate.Results: Sixteen dislocations were included. Nine (56%) were due to public road accidents, 5 (31%) were due to falls from height, and 2 (13%) were due to sports injuries. Dislocation had occurred in the posterior location in 8 (50%) cases. Regarding arterial injury, there were 7 (44%) ruptures, 7 (44%) dissections, and 2 (13%) isolated thromboses. Eleven (69%) KDs with vascular trauma were associated with signs of acute ischemia. Revascularization was achieved by anatomical venous bypass in 14 (88%), resection and direct anastomosis in one (6%), and isolated thrombectomy in one (6%). Median time to surgery (time between trauma and vascular repair) was 7 hours (3.25-60.92 hours). Primary revascularization was performed in 12 (75%) cases. In three cases (19%), orthopedic reduction and stabilization were performed first. In one case, (6%) three-step management with vascular shunt at first, then with knee stabilization, and finally vascular bypass was carried out. Stabilization was achieved by using an external fixator in 13 (82%) cases, by open reduction and internal fixation in one case (6%), by ligamentoplasty in one (6%), and by using a long leg cast in one (6%). Fasciotomy was required in 12 (75%) cases. Two patients had early vascular complications, and 2 had early systemic complications. Three secondary transfemoral amputations were performed. Median follow-up duration was 23 months. No secondary amputation was recorded. At the end of follow-up, functional outcomes were evaluated using the Oxford Knee Score (OKS). The median OKS was 30 versus the pretrauma median OKS of 47 (P < 0.00028). No risk factor associated with limb amputation has been highlighted.Conclusions: Analysis of these results provided indications for therapeutic management of this condition. This study shows poor functional outcomes because of severity of vascular lesion in patients with orthopedic trauma but with healthy arteries.

New Findings: What is the central question of this study? Moving to supine induces upper airway modifications and a fluid shift to the neck, which represent inspiratory load that predisposes to upper airway collapse.Is there cortical participation in the response to the load induced by transition to a supine posturein awake healthy subjects? What is the main finding and its importance? Moving to supine induces transient cortical activation in awake healthy subjects, with greater fluid shift, supporting possible cortical participation in the response to upper airway load induced by transition to a supine posture. Our findings open new perspectives in the understanding of the pathogenesis of obstructive sleep apnoea. Abstract: Moving from sitting upright to lying supine causes anatomical modifications and a fluid shift to the neck, which represent inspiratory loads that predispose to upper airway collapse. The pre-inspiratory potential (PIP) corresponds to the cortical activity observed during inspiratory load. In the sitting position during wakefulness, some obstructive sleep apnoea patients exhibit PIP, probably in relationship to upper airway abnormalities. The aim of this study was to investigate whether moving to the supine position induces respiratory-related cortical activation (PIP) in awake healthy subjects. The ECG was analysed to detect PIP, and EMG activity of the genioglossus muscle and ventilation were measured in the sitting position, immediately after moving to the supine position, and during application of leg positive pressure in the supine position to promote fluid shift, which was measured by bioelectrical impedance. Twenty-four subjects were included. From sitting to lying, PIP prevalence increased from 1/24 to 11/24 (P=0.002), and ventilation decreased with no change in genioglossus activity. The fluid shift from sitting to supine was higher in the subjects exhibiting PIP while supine compared with the subjects without PIP [median (25th; 75th centiles) 440(430; 520) versus 320(275; 385)ml, P=0.018], without any other differences. From before to during leg positive pressure, PIP disappeared (P=0.006). These results indicate that moving from sitting to lying induces transient respiratory-related cortical activity in awake healthy subjects with greater fluid shift, supporting possible cortical participation in the response to upper airway loading induced by moving from sitting upright to lying supine. This study offers new perspectives in the understanding of obstructive sleep apnoea pathogenesis.

International audience; PURPOSE: The majority of terrorist acts are carried out by explosion or shooting. The objective of this study was first, to describe the management implemented to treat a large number of casualties and their flow together with the injuries observed, and second, to compare these resources according to the mechanism of trauma.METHODS: This retrospective cohort study collected medical data from all casualties of the attacks on November 13th 2015 in Paris, France, with physical injuries, who arrived alive at any hospital within the first 24 h after the events. Casualties were divided into two groups: explosion injuries and gunshot wounds.RESULTS: 337 casualties were admitted to hospital, 286 (85%) from gunshot wounds and 51 (15%) from explosions. Gunshot casualties had more severe injuries and required more in-hospital resources than explosion casualties. Emergency surgery was required in 181 (54%) casualties and was more frequent for gunshot wounds than explosion injuries (57% vs. 35%, p

Background Although prehospital cardiac arrest (CA) remains associated with poor long-term outcome, recent studies show an improvement in the survival rate after prehospital trauma associated CA (TCA). However, data on the long-term neurological outcome of TCA, particularly from physician-staffed Emergency Medical Service (EMS), are scarce, and results reported have been inconsistent. The objective of this pilot study was to evaluate the long-term outcome of patients admitted to several trauma centres after a TCA. Methods This study is a retrospective database review of all patients from a multicentre prospective registry that experienced a TCA and had undergone successful cardiopulmonary resuscitation (CPR) prior their admission at the trauma centre. The primary end point was neurological outcome at 6 months among patients who survived to hospital discharge. Results 88 victims of TCA underwent successful CPR and were admitted to the hospital, 90% of whom were victims of blunt trauma. Of these 88 patients, 10 patients (11%; CI 95% 6% to 19%) survived to discharge: on discharge, 9 patients displayed a GCS of 15 and Cerebral Performance Categories (CPC) 1-2 and one patient had a GCS 7 and CPC of 3. Hypoxia was the most frequent cause of CA among survivors. 6-month follow-up was achieved for 9 patients of the 10 surviving patients. The 9 patients with a good outcome on hospital discharge had a CPC of 1 or 2 6 months post discharge. All returned to their premorbid family and social settings. Conclusions Among patients admitted to hospital after successful CPR from TCA, hypoxia as the likely aetiology of arrest carried a more favourable prognosis. Most of the patients successfully resuscitated from TCA and surviving to hospital discharge had a good neurological outcome, suggesting that prehospital resuscitation may not be futile.

Background The diagnosis of small bowel and mesenteric injuries (BBMI) after blunt abdominal trauma remains difficult, which results in delayed treatment and increased mortality and morbidity. Diagnostic peritoneal lavage (DPL) in patients with 1 or 2 abnormal CT findings that are suggestive of BBMI was proposed, but the rate of unnecessary surgical exploration remains high. Patients and methods Blunt abdominal trauma patients with 1 or 2 CT findings predictive of BBMI from 2001 to 2014 underwent a DPL with calculation of a cell count ratio (CCR) dividing the ratio of white blood cells (WBCs) to red blood cells (RBCs) (WBC/RBC ratio) in the lavage fluid by the WBC/RBC ratio in peripheral blood. Surgical exploration of the abdomen was performed immediately in cases with a CCR ≥ 1. CT findings, DPL and surgery results, and global outcome were analyzed. Results Thirty-seven were included in the study (27 males, median age of 30 years (range, 17–69 years)). Exploratory laparotomy was performed in 24 patients (65%). Sixteen patients (67%) had BBMI: 7 hollow organ perforations or tears (29%), including 4 bowel resection with primary anastomosis and 3 single sutures, and 9 patients had mesenteric injuries. CT findings associated with BBMI and hollow organ perforation were large peritoneal effusion ( p = 0.02) and small bowel wall abnormalities ( p = 0.002). No postoperative complications were observed. Sensitivity and specificity of DPL for the diagnosis of bowel injuries were respectively 100% (CI 95% [59–100]) and 43% (CI 95% [25–63]). The sensitivity remained 100% (CI 95% [59–100]) when the ratio was ≥4 ( n = 10 patients), and the specificity reached 90% (CI 95% [73–98]). Conclusion DPL is sensitive for the diagnosis of BBMI in stable trauma patients with 1 or 2 unexplained CT abnormalities, but specificity is low with a high rate of nontherapeutic laparotomy in case of CCR ≥ 1. Indications for exploratory laparotomy could be restricted to patients with a CCR ≥ 4 to improve the specificity of diagnosis management.

The presence of a respiratory-related cortical activity during tidal breathing is abnormal and a hallmark of respiratory difficulties, but its detection requires superior discrimination and temporal resolution. The aim of this study was to validate a computational method using EEG covariance (or connectivity) matrices to detect a change in brain activity related to breathing. In 17 healthy subjects, EEG was recorded during resting unloaded breathing (RB), voluntary sniffs, and breathing against an inspiratory threshold load (ITL). EEG were analyzed by the specially developed covariance-based classifier, event-related potentials, and time-frequency (T-F) distributions. Nine subjects repeated the protocol. The classifier could accurately detect ITL and sniffs compared with the reference period of RB. For ITL, EEG-based detection was superior to airflow-based detection ( P < 0.05). A coincident improvement in EEG-airflow correlation in ITL compared with RB ( P < 0.05) confirmed that EEG detection relates to breathing. Premotor potential incidence was significantly higher before inspiration in sniffs and ITL compared with RB ( P < 0.05), but T-F distributions revealed a significant difference between sniffs and RB only ( P < 0.05). Intraclass correlation values ranged from poor (−0.2) to excellent (1.0). Thus, as for conventional event-related potential analysis, the covariance-based classifier can accurately predict a change in brain state related to a change in respiratory state, and given its capacity for near “real-time” detection, it is suitable to monitor the respiratory state in respiratory and critically ill patients in the development of a brain-ventilator interface.

Receiving a great number of firearms casualties in a trauma center requires a preexisting plan. This plan must define the different steps, starting from patients' arrival preparation to operating room occupation. It must also define how the involved physicians and nurses interact with each other. The delay between the alert and the first patients' arrival is dedicated to staff recruitment among those who are on duty, and staff recall of those who are at home or on call. The two main pieces of the puzzle that can prevent trauma center saturation are a one-way patient influx and a sufficient amount of staff physicians and nurses leaded by a medical director. We present the organization of a level-1 trauma center that received 53 casualties from the Paris attacks on November the 13th 2015, including 28 absolute emergencies. We subsequently provide feedback including the keys of success and stumbling blocks. Language: fr

International audience; Respiratory-related premotor potentials from averaged electroencephalography (EEG) over the motor areas indicate cortical activation in healthy participants to maintain ventilation in the face of moderate inspiratory or expiratory loads. These experimental conditions are associated with respiratory discomfort, i.e., dyspnea. Premotor potentials are also observed in resting breathing in patients with reduced automatic respiratory drive or respiratory muscle strength due to respiratory or neurological disease, presumably in an attempt to maintain ventilation. The aim of this study was to determine if small voluntary increases in ventilation or smaller load-capacity imbalances, that generate an awareness of breathing but aren't necessarily dyspneic, give rise to respiratory premotor potentials in healthy participants. In 15 healthy subjects, EEG was recorded during voluntary large breaths (∼3× tidal volume, that were interspersed with smaller non-voluntary breaths in the same trial; in 10 subjects) and breathing with a 'low' inspiratory threshold load (∼7 cmH2O; in 8 subjects). Averaged EEG signals at Cz and FCz were assessed for premotor potentials prior to inspiration. Premotor potential incidence in large breaths was 40%, similar to that in the smaller non-voluntary breaths in the same trial (20%; p > 0.05) and to that in a separate trial of resting breathing (0%; p > 0.05). The incidence of premotor potentials was 25% in the low load condition, similar to that in resting breathing (0%; p > 0.05). In contrast, voluntary sniffs were always associated with a higher incidence of premotor potentials (100%; p < 0.05). We have demonstrated that in contrast to respiratory and neurological disease, there is no significant cortical contribution to increase tidal volume or to maintain the load-capacity balance with a small inspiratory threshold load in healthy participants as detected using event-related potential methodology. A lack of cortical contribution during loading was associated with low ratings of respiratory discomfort and minimal changes in ventilation. These findings advance our understanding of the neural control of breathing in health and disease and how respiratory-related EEG may be used for medical technologies such as brain-computer interfaces.

Speech or programmed sentences must often be interrupted in order to listen to and interact with interlocutors. Among many processes that produce such complex acts, the brain must precisely adjust breathing to produce adequate phonation. The mechanism of these adjustments is multifactorial and still poorly understood. In order to selectively examine the adjustment in breath control, we recorded respiratory-related premotor cortical potentials from the scalp of human subjects while they performed a single breathing initiation or inhibition task. We found that voluntary breathing is initiated if, and only if, the cortical premotor potential activity reaches a threshold activation level. The stochastic variability in the threshold correlates to the distribution of initiation times of breathing. The data also fitted a computerized interactive race model. Modeling results confirm that this model is also as effective in respiratory modality, as it has been found to be for eye and hand movements. No modifications were required to account for respiratory cycle inhibition processes. In this overly simplified task, we showed a link between voluntary initiation and control of breathing and activity in a fronto-median region of the cerebral cortex. These results shed light on some of the physiological constraints involved in the complex mechanisms of respiration, phonation, and language.

Background: Although cardio-respiratory (CR) system is generally controlled by the autonomic nervous system, interactions between the cortex and these primary functions are receiving an increasing interest in neurosciences. New method: In general, the timing of such internally paced events (e.g. heartbeats or respiratory cycles) may display a large variability. For the analysis of such CR event-related EEG potentials, a baseline must be correctly associated to each cycle of detected events. The open-source toolbox CARE-rCortex provides an easy-to-use interface to detect CR events, define baselines, and analyse in time-frequency (TF) domain the CR-based EEG potentials. Results: CARE-rCortex provides some practical tools to detect and validate these CR events. Users can define baselines time-locked to a phase of respiratory or heart cycle. A statistical test has also been integrated to highlight significant points of the TF maps with respect to the baseline. We illustrate the use of CARE-rCortex with the analysis of two real cardio-respiratory datasets. Comparison with existing methods: Compared to other open-source toolboxes, CARE-rCortex allows users to automatically detect CR events, to define and check baselines for each detected event. Different baseline normalizations can be used in the TF analysis of EEG epochs. Conclusions: The analysis of CR-related EEG activities could provide valuable information about cognitive or pathological brain states. CARE-rCortex runs in Matlab as a plug-in of the EEGLAB software, and it is publicly available at https://github.com/FannyGrosselin/CARE-rCortex., This manuscript contains 13 pages including 7 color figures

Background Organ failure, including acute kidney injury (AKI), is the third leading cause of death after bleeding and brain injury in trauma patients. We sought to assess the prevalence, the risk factors and the impact of AKI on outcome after trauma. Methods We performed a retrospective analysis of prospectively collected data from a multicenter trauma registry. AKI was defined according to the risk, injury, failure, loss of kidney function and end-stage kidney disease (RIFLE) classification from serum creatinine only. Prehospital and early hospital risk factors for AKI were identified using logistic regression analysis. The predictive models were internally validated using bootstrapping resampling technique. Results We included 3111 patients in the analysis. The incidence of AKI was 13% including 7% stage R, 3.7% stage I and 2.3% stage F. AKI incidence rose to 42.5% in patients presenting with hemorrhagic shock; 96% of AKI occurred within the 5 first days after trauma. In multivariate analysis, prehospital variables including minimum prehospital mean arterial pressure, maximum prehospital heart rate, secondary transfer to the trauma center and data early collected after hospital admission including injury severity score, renal trauma, blood lactate and hemorrhagic shock were independent risk factors in the models predicting AKI. The model had good discrimination with area under the receiver operating characteristic curve of 0.85 (0.82–0.88) to predict AKI stage I or F and 0.80 (0.77–0.83) to predict AKI of all stages. Rhabdomyolysis severity, assessed by the creatine kinase peak, was an additional independent risk factor for AKI when it was forced into the model (OR 1.041 (1.015–1.069) per step of 1000 U/mL, p

Les fractures de l’extremite superieure du femur (FESF) representent un enjeu de sante publique chez les patients âges, en raison de leur frequence et de leur severite, dues en particulier aux comorbidites presentes chez ces patients. Un tiers des patients âges ayant une FESF decede dans l’annee qui suit, et chez les survivants, on observe une degradation de l’autonomie et de la qualite de vie. L’une des grandes difficultes de leur prise en charge reside dans le parcours de soins que represente l’hospitalisation de ces patients, comprenant l’admission aux urgences, l’intervention chirurgicale, l’anesthesie, la prise en charge au decours puis en rehabilitation, dont chaque etape requiert une prise en compte des particularites des patients geriatriques (vulnerabilite, multicomorbidites, polymedication, et frequence des complications postoperatoires). Au sein de ce parcours, les principales pistes d’amelioration reposent sur l’amelioration du delai chirurgical et la creation de filieres efficaces d’orthogeriatrie, dont le benefice devra etre confirme par des etudes a venir.

International audience; Despite orthogeriatric management, 12% of the elderly experienced PUs after hip fracture surgery. PUs were significantly associated with a low albumin level, history of atrial fibrillation coronary artery disease, and diabetes. The risk ratio of death at 6 months associated with pressure ulcer was 2.38 (95% CI 1.31-4.32%, p = 0.044).Introduction: Pressure ulcers in hip fracture patients are frequent and associated with a poor outcome. An orthogeriatric management, recommended by international guidelines in hip fracture patients and including pressure ulcer prevention and treatment, could influence causes and consequences of pressure ulcer. However, remaining factors associated with pressure ulcer occurrence and prognostic value of pressure ulcer in hip fracture patients managed in an orthogeriatric care pathway remain unknown.Methods: From June 2009 to April 2015, all consecutive patients with hip fracture admitted to a unit for Post-operative geriatric care were evaluated for eligibility. Patients were included if their primary presentation was due to hip fracture and if they were ≥ 70 years of age. Patients were excluded in the presence of pathological fracture or if they were already hospitalized at the time of the fracture. In our unit, orthogeriatric principles are implemented, including a multi-component intervention to improve pressure ulcer prevention and management. Patients were followed-up until 6 months after discharge.Results: Five hundred sixty-seven patients were included, with an overall 14.4% 6-month mortality (95% CI 11.6-17.8%). Of these, 67 patients (12%) experienced at least one pressure ulcer. Despite orthogeriatric management, pressure ulcers were significantly associated with a low albumin level (RR 0.90, 95% CI 0.84-0.96; p = 0.003) and history of atrial fibrillation (RR 1.91, 95% CI 1.05-3.46; p = 0.033), coronary artery disease (RR 2.16, 95% CI 1.17-3.99; p = 0.014), and diabetes (RR 2.33, 95% CI 1.14-4.75; p = 0.02). A pressure ulcer was associated with 6-month mortality (RR 2.38, 95% CI 1.31-4.32, p = 0.044).Conclusion: In elderly patients with hip fracture managed in an orthogeriatric care pathway, pressure ulcer remained associated with poorly modifiable risk factors and long-term mortality.

International audience; Chest trauma remains an issue for health services for both severe and apparently mild trauma management. Severe chest trauma is associated with high mortality and is considered liable for 25% of mortality in multiple traumas. Moreover, mild trauma is also associated with significant morbidity especially in patients with preexisting conditions. Thus, whatever the severity, a fast-acting strategy must be organized. At this time, there are no guidelines available from scientific societies. These expert recommendations aim to establish guidelines for chest trauma management in both prehospital an in hospital settings, for the first 48 hours. The ``Societe francaise d'anesthesie reanimation'' and the ``Societe francaise de mdecine d'urgence'' worked together on the 7 following questions: (1) criteria defining severity and for appropriate hospital referral; (2) diagnosis strategy in both pre- and in-hospital settings; (3) indications and guidelines for ventilatory support; (4) management of analgesia; (5) indications and guidelines for chest tube placement; (6) surgical and endovascular repair indications in blunt chest trauma; (7) definition, medical and surgical specificity of penetrating chest trauma. For each question, prespecified ``crucial'' (and sometimes also ``important'') outcomes were identified by the panel of experts because it mattered for patients. We rated evidence across studies for these specific clinical outcomes. After a systematic Grade (R) approach, we defined 60 recommendations. Each recommendation has been evaluated by all the experts according to the DELPHI method. (C) 2017 Societe francaise d'anesthesie et de reanimation (Sfar). Published by Elsevier Masson SAS.
