ABSTRACT
BACKGROUND: Recent studies highlight that female anaesthesiology researchers have lower visibility on professional social networks (PSNs) than male researchers. OBJECTIVE: The objective of this work was to compare the use of PSNs between women and men in critical care research. METHODS: We included the first/last authors (FAs/LAs) among the most frequently cited articles in 2018 and 2019 in three critical care journals (Intensive Care Medicine, Critical Care Medicine, and Critical Care). We compared the use of three PSNs-Twitter, ResearchGate, and LinkedIn-between women and men in the FA/LA positions. RESULTS: We analysed 494 articles, which allowed us to include 426 FAs and 383 LAs. The use of a PSN was similar between women and men (Twitter: 35 vs. 31% FA p = 0.76, 38 vs. 31% LA p = 0.24; ResearchGate: 60 vs. 70% FA p = 0.06, 67 vs. 66% LA p = 0.95; LinkedIn: 54 vs. 56% FA p = 0.25, 68 vs. 64% LA p = 0.58; respectively). On ResearchGate, women had a lower reputation score (FA group 26.4 [19.5-31.5] vs. 34.8 [27.4-41.6], p < 0.01; LA group 38.5 [30.9-43.7] vs. 42.3 [37.6-46.4], p < 0.01) and fewer followers (FA group 28.5 [19-45] vs. 68.5 [72,5-657] p < 0.01; LA group 96.5 [43,8-258] vs. 178 [76.3-313.5] p = 0.02). Female researchers were FAs in 30% of the articles and LAs in 16%. CONCLUSION: In the field of critical care, the visibility of female researchers on the social networks dedicated to scientific research is lower than that of male researchers.

BACKGROUND: Although diarrhoea is a real source of morbidity for critically ill patients, this issue has been little studied, making it difficult to understand its mechanisms and management. AIMS: We conducted a quality improvement study in an adult surgical intensive care unit before/after the implementation of a specific protocol to firstly improve diarrhoea management for patient benefit and secondly to understand the impact on caregivers. STUDY DESIGN: The first part of this before/after study consisted in assessing the proportion of patients receiving an anti-diarrheal treatment before (phase I)/after (phase II) the implementation of the protocol. The second part of the study was to survey the caregivers on this topic. RESULTS: Sixty four adults were included (33 in phase I; 31 in phase II) with 280 diarrheal episodes (129 in phase I; 151 in phase II). The proportion of patients who received at least one anti-diarrheal treatment was similar between the two phases (79% (26/33) vs. 68% (21/31), p = .40). Diarrhoea incidence was also similar (9% (33 patients/368 admissions) vs. 11% (31 patients/275 admissions), p = .35). The delay to initiate at least one treatment was significantly shorter in phase II (2 days [1-7] vs. 0 day [0-2]; p < .001). The patients' rehabilitation was no longer impacted by the occurrence of a diarrheal episode in phase II (39% (13/33) vs. 0% (0/31), p < .001). Eighty team members completed the surveys in phase I and 70 in phase II. Caregivers perceived diarrhoea like a burden and its economic impact remained high. CONCLUSIONS: The implementation of a protocol for the management of ICU diarrhoea did not increase the proportion of patients treated, but it did significantly improve the delay to initiate a treatment. The patients' rehabilitation was no longer affected by diarrhoea. RELEVANCE TO CLINICAL PRACTICE: The use of specific anti-diarrhoea guidelines may help to reduce the burden of diarrhoea in an ICU.

OBJECTIVES: The aims of the current study were 1) to provide the prevalence of five types of gender-based violence (GBV) among male and female healthcare students; 2) to describe perpetrators' status, where the GBV occurred, and psychological and behavioural impacts of the GBV; and 3) to identify factors associated with GBV. DESIGN: A cross-sectional study was conducted among voluntary healthcare students in France. SETTING: Health Campus at Rouen and nursing schools in Normandy, France. PARTICIPANTS: Volunteer healthcare students of 18 years and over. DATA COLLECTED: Five types of GBV were recorded: GBV1: damage to a person's image due to a sexual connotation on social networks, GBV2: sexist remarks and behaviour, GBV3: comments with sexual connotations, GBV4: sexual assaults and GBV5: rape or attempted rape. Perpetrators' status, where the GBV occurred, psychological and behavioural impacts of GBV were also recorded. RESULTS: One thousand one hundred and fifty-two students were included. The mean age was 20.8 years (SD = 2.26), 82.6% of students were women (0.4% non-binary). Since the beginning of their healthcare study, 41.2% of students CI 95% [39.7-42.6] were victim of at least one type of GBV: 15.8% among men CI 95% [13.2-18.4] and 46.0% CI 95% [44.4-47.6] among women (p < 0.001). The perpetrators were student peers, regardless of the type of GBV, healthcare workers for the GB2 and GBV3, and patients except for GBV5. The main consequences of GBV on health was psychological and eating related. After multivariate analysis, being a woman, LGBTQ+ (Lesbian, Gay, Bi, Trans, Queer and other), a nurse, a physiotherapist student, having a job, living with roommates and year of study were risk factors for GBV. CONCLUSION: GBV is so common at healthcare universities and could have such severe consequences for students that more work is needed to generate a culture change and ensure safe learning environments.

INTRODUCTION: In case of COVID-19 related scarcity of critical care resources, an early French triage algorithm categorized critically ill patients by probability of survival based on medical history and severity, with four priority levels for initiation or continuation of critical care: P1 -high priority, P2 -intermediate priority, P3 -not needed, P4 -not appropriate. This retrospective multi-center study aimed to assess its classification performance and its ability to help saving lives under capacity saturation. METHODS: ICU patients admitted for severe COVID-19 without triage in spring 2020 were retrospectively included from three hospitals. Demographic data, medical history and severity items were collected. Priority levels were retrospectively allocated at ICU admission and on ICU day 7-10. Mortality rate, cumulative incidence of death and of alive ICU discharge, length of ICU stay and of mechanical ventilation were compared between priority levels. Calculated mortality and survival were compared between full simulated triage and no triage. RESULTS: 225 patients were included, aged 63.1±11.9 years. Median SAPS2 was 40 (IQR 29-49). At the end of follow-up, 61 (27%) had died, 26 were still in ICU, and 138 had been discharged. Following retrospective initial priority allocation, mortality rate was 53% among P4 patients (95CI 34-72%) versus 23% among all P1 to P3 patients (95CI 17-30%, chi-squared p = 5.2e-4). The cumulative incidence of death consistently increased in the order P3, P1, P2 and P4 both at admission (Gray's test p = 3.1e-5) and at reassessment (p = 8e-5), and conversely for that of alive ICU discharge. Reassessment strengthened consistency. Simulation under saturation showed that this two-step triage protocol could have saved 28 to 40 more lives than no triage. CONCLUSION: Although it cannot eliminate potentially avoidable deaths, this triage protocol proved able to adequately prioritize critical care for patients with highest probability of survival, hence to save more lives if applied.

BACKGROUND: The benefit of a stay in an intensive care unit (ICU) is not certain for older patients, particularly in the surgical context. AIMS: The objective of this study was to identify the factors associated with an unfavourable outcome in this population. DESIGN: Prospective, descriptive, monocentric study conducted in the surgical ICU of a French university hospital. METHODS: Patients aged ≥75 years admitted in the surgical ICU for a predicted length of stay ≥48 hours were included. Patients received an initial and a 6-months nutritional and functional assessment performed by physicians and nurses. The outcome was considered as favourable if the Katz Activities of Daily Living (ADL) variation (ADL delta = 6-months ADL - ICU admission ADL) was between 0 and -0.5 point 6 months after ICU discharge and unfavourable if the ADL delta decreased by more than 0.5 points or if the patient had died 6 months after ICU discharge. RESULTS: Fifty-six patients-32 (57%) male-aged 79 [77; 83] y were included. ICU mortality was 19%; 6-month mortality was 22%. Median ADL delta was -0.5 [-0.5-0] points. A low ADL score (P = .0438) and a low albumin level (P = .0213) at admission were the two independent factors associated with an unfavourable outcome. CONCLUSION: Mortality and loss of independence were high in this elderly population during and after their surgical ICU stay. The benefit of a systematic collaboration between intensive care specialists, ICU nurses, and geriatricians, to assess and manage nutritional and functional problems and to prevent a pejorative outcome in patients over 75 years old admitted in surgical ICU needs to be studied. RELEVANCE TO CLINICAL PRACTICE: There should be systematic screening for objective markers of undernutrition and frailty on ICU admission of older patients as they are associated with a poor prognosis.

Current guidelines recommend monitoring the anticoagulant effect of unfractionated heparin (UFH) by measuring anti-Xa activity rather than activated partial thromboplastin time (aPTT) in intensive care unit (ICU) patients. The primary objective of this study was to evaluate the correlation of aPTT, anti-Xa activity, and thrombin generation in UFH-treated ICU patients. A prospective observational pilot study was conducted in adult surgical ICU patients treated with UFH. aPTT and anti-Xa activity were monitored daily. The therapeutic target was aPTT between 50 s and 84 s, and/or anti-Xa between 0.3 and 0.7 U/mL. Correlation among aPTT, anti-Xa activity, and thrombin generation was determined by measuring endogenous thrombin potential (ETP), with the inflammatory response evaluated. C-reactive protein (CRP) was used as a marker of inflammatory response. The plasma of 107 samples from 30 ICU patients was analyzed. The correlation between aPTT and anti-Xa activity was 0.66, CI95% [0.54;0.76] (p < 0.0001). Although thrombin generation, aPTT, and anti-Xa were correlated with inflammatory responses, the correlation was higher with thrombin generation and anti-Xa activity compared to aPTT. When aPTT was in a therapeutic range, a low thrombin generation was observed but was 50% inhibited when anti-Xa was in a therapeutic range. Coagulation testing with aPTT, anti-Xa correlated with thrombin generation. A 50% decrease in thrombin generation was observed when anti-Xa was within a therapeutic range. Further work is needed to evaluate coagulation biomarker responses and clinical outcomes in specific ICU populations.

PURPOSE: Intensive care medicine (ICM) has the particularity of being a multidisciplinary specialty and its literature reflects this multidisciplinarity. However, the proportion of each field in this literature and its trend dynamics are not known. The objective of this study was to analyze the ICM literature, extract latent topics and search for the presence of research trends. MATERIAL AND METHODS: Abstracts of original articles from the top ICM journals, from their inception until December 31st, 2019, were included. This corpus was fed into a structural topic modeling algorithm to extract latent semantic topics. The temporal distribution was then analyzed and the presence of trends was searched by Mann-Kendall trends tests. RESULTS: Finally, 49,276 articles from 10 journals were included. After topic modeling analysis and experts' feedback, 124 research topics were selected and labeled. Topics were categorized into 19 categories, the most represented being respiratory, fundamental and neurological research. Increasing trends were observed for research on mechanical ventilation and decreasing trends for cardiopulmonary resuscitation. CONCLUSIONS: This study reviewed all articles from major ICM journals in a comprehensive way. It provides a better understanding of ICM research landscape by analyzing the temporal evolution of latent research topics in the ICM literature.

The routine use of mechanical circulatory support during lung transplantation (LTx) is still controversial. The use of prophylactic human albumin (HA) or hypertonic sodium lactate (HSL) prime in mechanical circulatory support during LTx could prevent ischemia−reperfusion (IR) injuries and pulmonary endothelial dysfunction and thus prevent the development of pulmonary graft dysfunction. The objective was to investigate the impact of cardiopulmonary bypass (CPB) priming with HA and HSL compared to a CPB prime with Gelofusine (GF) on pulmonary endothelial dysfunction in a lung IR rat model. Rats were assigned to four groups: IR-CPB-GF group, IR-CPB-HA group, IR-CPB-HSL group and a sham group. The study of pulmonary vascular reactivity by wire myograph was the primary outcome. Glycocalyx degradation (syndecan-1 and heparan) was also assessed by ELISA and electron microscopy, systemic and pulmonary inflammation by ELISA (IL-1ß, IL-10, and TNF-α) and immunohistochemistry. Clinical parameters were evaluated. We employed a CPB model with three different primings, permitting femoral−femoral assistance with left pulmonary hilum ischemia for IR. Pulmonary endothelium-dependent relaxation to acetylcholine was significantly decreased in the IR-CPB-GF group (11.9 ± 6.2%) compared to the IR-CPB-HA group (52.8 ± 5.2%, p < 0.0001), the IR-CPB-HSL group (57.7 ± 6.3%, p < 0.0001) and the sham group (80.8 ± 6.5%, p < 0.0001). We did not observe any difference between the groups concerning glycocalyx degradation, and systemic or tissular inflammation. The IR-CPB-HSL group needed more vascular filling and developed significantly more pulmonary edema than the IR-CPB-GF group and the IR-CPB-HA group. Using HA as a prime in CPB during Ltx could decrease pulmonary endothelial dysfunction's IR-mediated effects. No effects of HA were found on inflammation.

Introduction: Anesthesia remains a young medical discipline still relatively unknown by the general public and probably by some health professionals. The objective of the study was to evaluate the perception of anesthesiologist by health professionals working with this specialty. Methods: We distributed a computerized survey to physicians, residents, paramedical, midwives, and administrative staff in different hospitals between April and July 2018 in Normandy, France. The survey included 38 questions on 6 different topics: communicated image, skills and knowledge, communication, place in patient care, workload, and initial anesthesiologist formation. The survey was validated by a semi-directive interview methodology. A Likert scale from ×2 to +2 ("completely disagree" to "completely agree") was used for each item. Results: Six hundred and twenty five out of 2,000 surveys sent were analyzed. The anesthesiologist conveys an image of serenity (+0.94 ± 0.79), has a high degree of responsibility (+1.72 ± 0.59) with important decision-making power (+1.39 ± 0.82). He guarantees patient safety and comfort (+1.07 ± 0.88) with his/her dual competence in anesthesia and intensive care (+1.36 ± 0.82). Anesthesiology requires teamwork (+1.68 ± 0.58) and good communication skills (+1.48 ± 0.73). The anesthesiologist is not perceived as a service provider (-0.33 ± 1.15) but is the physician responsible for perioperative care (+1.69 ± 1.00). His/her workload is moderately perceived as high (+0.71 ± 1.17) but is confronted with potentially conflictual relationships with colleagues from other specialties (+1.40 ± 0.68) and stressful situations (+1.44 ± 0.80). Conclusion: The overall perception of the anesthesiologist in our study appears to be good.
ABSTRACT
PURPOSE: Duration of antibiotic therapy for ventilator-associated pneumonia (VAP) due to non-fermenting Gram-negative bacilli (NF-GNB), including Pseudomonas aeruginosa (PA) remains uncertain. We aimed to assess the non-inferiority of a short duration of antibiotics (8 days) vs. prolonged antibiotic therapy (15 days) in VAP due to PA (PA-VAP). METHODS: We conducted a nationwide, randomized, open-labeled, multicenter, non-inferiority trial to evaluate optimal duration of antibiotic treatment in PA-VAP. Eligible patients were adults with diagnosis of PA-VAP and randomly assigned in 1:1 ratio to receive a short-duration treatment (8 days) or a long-duration treatment (15 days). A pre-specified analysis was used to assess a composite endpoint combining mortality and PA-VAP recurrence rate during hospitalization in the intensive care unit (ICU) within 90 days. RESULTS: The study was stopped after 24 months due to slow inclusion rate. In intention-to-treat population (n = 186), the percentage of patients who reached the composite endpoint was 25.5% (N = 25/98) in the 15-day group versus 35.2% (N = 31/88) in the 8-day group (difference 9.7%, 90% confidence interval (CI) -1.9%-21.2%). The percentage of recurrence of PA-VAP during the ICU stay was 9.2% in the 15-day group versus 17% in the 8-day group. The two groups had similar median days of mechanical ventilation, of ICU stay, number of extra pulmonary infections and acquisition of multidrug-resistant (MDR) pathogens during ICU stay. CONCLUSIONS: Our study failed to show the non-inferiority of a short duration of antibiotics in the treatment of PA-VAP, compared to a long duration. The short duration strategy may be associated to an increase of PA-VAP recurrence. However, the lack of power limits the interpretation of this study.

INTRODUCTION: Intra-abdominal infections represent the second most frequently acquired infection in the intensive care unit (ICU), with mortality rates ranging from 20% to 50%. Candida spp. may be responsible for up to 10-30% of cases. This study assesses risk factors for development of intra-abdominal candidiasis (IAC) among patients admitted to ICU. METHODS: We performed a case-control study in 26 European ICUs during the period January 2015-December 2016. Patients at least 18 years old who developed an episode of microbiologically documented IAC during their stay in the ICU (at least 48 h after admission) served as the case cohort. The control group consisted of adult patients who did not develop episodes of IAC during ICU admission. Matching was performed at a ratio of 1:1 according to time at risk (i.e. controls had to have at least the same length of ICU stay as their matched cases prior to IAC onset), ICU ward and period of study. RESULTS: During the study period, 101 case patients with a diagnosis of IAC were included in the study. On univariate analysis, severe hepatic failure, prior receipt of antibiotics, prior receipt of parenteral nutrition, abdominal drain, prior bacterial infection, anastomotic leakage, recurrent gastrointestinal perforation, prior receipt of antifungal drugs and higher median number of abdominal surgical interventions were associated with IAC development. On multivariate analysis, recurrent gastrointestinal perforation (OR 13.90; 95% CI 2.65-72.82, p = 0.002), anastomotic leakage (OR 6.61; 95% CI 1.98-21.99, p = 0.002), abdominal drain (OR 6.58; 95% CI 1.73-25.06, p = 0.006), prior receipt of antifungal drugs (OR 4.26; 95% CI 1.04-17.46, p = 0.04) or antibiotics (OR 3.78; 95% CI 1.32-10.52, p = 0.01) were independently associated with IAC. CONCLUSIONS: Gastrointestinal perforation, anastomotic leakage, abdominal drain and prior receipt of antifungals or antibiotics may help to identify critically ill patients with higher probability of developing IAC. Prospective studies are needed to identify which patients will benefit from early antifungal treatment.
ABSTRACT
INTRODUCTION: In 2015, France authorised controlled donation after circulatory death (cDCD) according to a nationally approved protocol. The aim of this study is to provide an overview from the perspective of critical care specialists of cDCD. The primary objective is to assess how the organ donation procedure affects the withdrawal of life-sustaining therapies (WLST) process. The secondary objective is to assess the impact of cDCD donors' diagnoses on the whole process. MATERIAL AND METHODS: This 2015-2019 prospective observational multicentre study evaluated the WLST process in all potential cDCD donors identified nationwide, comparing 2 different sets of subgroups: 1- those whose WLST began after organ donation was ruled out vs. while it was still under consideration; 2- those with a main diagnosis of post-anoxic brain injury (PABI) vs. primary brain injury (PBI) at the time of the WLST decision. RESULTS: The study analysed 908 potential cDCD donors. Organ donation remained under consideration at WLST initiation for 54.5% of them with longer intervals between their WLST decision and its initiation (2 [1-4] vs. 1 [1-2] days, P < 0.01). Overall, 60% had post-anoxic brain injury. Time from ICU admission to WLST decision was longer for primary brain injury donors (10 [4-21] vs. 6 [4-9] days, P < 0.01). Median time to death (agonal phase) was 15 [15-20] min. CONCLUSIONS: French cDCD donors are mostly related to post-anoxic brain injury. The organ donation process does not accelerate WLST decision but increases the interval between the WLST decision and its initiation.

BACKGROUND AND AIMS: Energy metabolism (energy deficit, substrate consumption) in the early phase of septic shock is not clearly understood. The objective of this study was to describe its evolution using indirect calorimetry. METHODS: Prospective observational pilot study including ventilated adult patients with septic shock admitted in a surgical intensive care unit (ICU). Metabolic data were collected using the COSMED Q-NRG + ® calorimeter: carbon dioxide production (VCO2), oxygen consumption (VO2), resting energy expenditure (REE), respiratory quotient (RQ) and the rate of substrate utilization (proteins, lipids, and carbohydrates). The main criterion was the evolution of the energy deficit (dE) from D1 to D6. RESULTS: In total, 34 patients were included and 15 patients (age: 57.6 ± 12.8 years; Simplified Acute Physiology Score II: 52 ± 11) were eligible for final analysis. Time for initiation of nutritional support was 2.5 ± 1.5 days. The dE improved during the study period (slope = 2.9 [1.8; 4.2]; p < 0.001). The REE remained stable during the first week with no significant variation (slope = -0.16 [-1.49; 0.79]; p = 0.78). The RQ remained stable overall (slope = 0.01 [0.00; 0.03]; p = 0.10). The substrates utilization significantly changed at D3 in favor of protein consumption (slope = 6.50 [4.44; 8.85]; p < 0.001) with an overall significant decrease in the consumption of non-protein substrates. CONCLUSION: Energy deficit improved while REE and RQ remained relatively stable during the first week of ICU stay. The significance of the variations of substrates consumption was unclear. These preliminary results should be further explored with larger studies.

BACKGROUND: The respiratory consequences of daily nursing care interventions in patients with acute respiratory distress syndrome (ARDS) are not clearly established. AIMS AND OBJECTIVES: The main objective of this study was to assess the feasibility of alveolar collapse analysis by the measurement of lung impedance distribution technique during nursing care in patients with ARDS. DESIGN: Prospective observational pilot physiologic study in a surgical intensive care unit of a tertiary care hospital including adult intubated patients with moderate-to-severe ARDS. METHODS: Each patient was monitored for 12 hours using a chest impedance device. Daily care interventions studied were as follows: endotracheal suctioning, mouth care, bed-bathing, and blood sampling. The primary endpoint was the variation in end-expiratory lung impedance (reflecting functional residual capacity) before and 1, 5, 15, and 30 minutes after nursing care interventions. Data are presented as median (interquartile-range). RESULTS: One hundred and eight events were collected in 18 patients. Endotracheal suctioning (n = 42), mouth care (n = 26), and bed-bathing (n = 23) induced a significant decrease in lung impedance after care: endotracheal suctioning (-40.0 [-53.8; -28.6]% at 1 minute [P < .001], -10.4 [-27.9; 1.8]% at 30 minutes [P = .03]; mouth care -17.9 [-45.4; -14.6]% at 1 minute [P < .001], -10.4 [-21.3; 3.4]% at 30 minutes [P = .01]; bed-bathing -40.2 [-53.5; -14.3]% at 1 minute [P < .001], -10.6 [-36.4; 1.6]% at 30 minutes [P = .01]). Blood sampling (n = 17) did not induce significant changes in lung impedance. CONCLUSIONS: The lung impedance distribution technique during nursing care appears feasible in the majority of patients with ARDS. Some daily nursing care in ARDS patients (including bed-bathing and mouth care) resulted in a prolonged decrease in lung functional residual capacity and therefore could be associated with pulmonary de-recruitment. RELEVANCE TO CLINICAL PRACTICE: A caregiver who has to assess the functional residual capacity of these patients should probably be informed of the schedules of the nursing care interventions.

BACKGROUND: Social networks are now essential tools for promoting research and researchers. However, there is no study investigating the link between presence or not on professional social networks and scientific publication or citation for a given researcher. OBJECTIVE: The objective of this study was to study the link between professional presence on social networks and scientific publications/citations among anesthesia researchers. METHODS: We included all the French full professors and associate professors of anesthesia. We analyzed their presence on the social networks Twitter (professional account with ≥1 tweet over the 6 previous months) and ResearchGate. We extracted their bibliometric parameters for the 2016-2020 period via the Web of Science Core Collection (Clarivate Analytics) database in the Science Citation Index-Expanded index. RESULTS: A total of 162 researchers were analyzed; 42 (25.9%) had an active Twitter account and 110 (67.9%) a ResearchGate account. There was no difference between associate professors and full professors regarding active presence on Twitter (8/23 [35%] vs. 34/139 [24.5%], respectively; P=.31) or ResearchGate (15/23 [65%] vs. 95/139 [68.3%], respectively; P=.81). Researchers with an active Twitter account (median [IQR]) had more scientific publications (45 [28-61] vs. 26 [12-41]; P<.001), a higher h-index (12 [8-16] vs. 8 [5-11]; P<.001), a higher number of citations per publication (12.54 [9.65-21.8] vs. 10.63 [5.67-16.10]; P=.01), and a higher number of citations (563 [321-896] vs. 263 [105-484]; P<.001). Researchers with a ResearchGate account (median [IQR]) had more scientific publications (33 [17-47] vs. 26 [9-43]; P=.03) and a higher h-index (9 [6-13] vs. 8 [3-11]; P=.03). There was no difference between researchers with a ResearchGate account and those without it concerning the number of citations per publication and overall number of citations. In multivariate analysis including sex, academic status, and presence on social networks, the presence on Twitter was associated with the number of publications (ß=20.2; P<.001), the number of citations (ß=494.5; P<.001), and the h-index (ß=4.5; P<.001). CONCLUSIONS: Among French anesthesia researchers, an active presence on Twitter is associated with higher scientific publication and citations.

INTRODUCTION: Pre-emptive inhaled antibiotics may be effective to reduce the occurrence of ventilator-associated pneumonia among critically ill patients. Meta-analysis of small sample size trials showed a favourable signal. Inhaled antibiotics are associated with a reduced emergence of antibiotic resistant bacteria. The aim of this trial is to evaluate the benefit of a 3-day course of inhaled antibiotics among patients undergoing invasive mechanical ventilation for more than 3 days on the occurrence of ventilator-associated pneumonia. METHODS AND ANALYSIS: Academic, investigator-initiated, parallel two group arms, double-blind, multicentre superiority randomised controlled trial. Patients invasively ventilated more than 3 days will be randomised to receive 20 mg/kg inhaled amikacin daily for 3 days or inhaled placebo (0.9% Sodium Chloride). Occurrence of ventilator-associated pneumonia will be recorded based on a standardised diagnostic framework from randomisation to day 28 and adjudicated by a centralised blinded committee. ETHICS AND DISSEMINATION: The protocol and amendments have been approved by the regional ethics review board and French competent authorities (Comité de protection des personnes Ouest I, No.2016-R29). All patients will be included after informed consent according to French law. Results will be disseminated in international scientific journals. TRIAL REGISTRATION NUMBERS: EudraCT 2016-001054-17 and NCT03149640.

BACKGROUND: Therapeutic failure is a frequent issue in the management of post-operative peritonitis. OBJECTIVES: A post hoc analysis of the prospective, multicentre DURAPOP trial analysed the risk factors for failures in post-operative peritonitis following adequate source control and empirical antibiotic therapy in critically ill patients. PATIENTS AND METHODS: Overall failures assessed post-operatively between Day 8 and Day 45 were defined as a composite of death and/or surgical and/or microbiological failures. Risk factors for failures were assessed using logistic regression analyses. RESULTS: Among the 236 analysed patients, overall failures were reported in 141 (59.7%) patients, including 30 (12.7%) deaths, 81 (34.3%) surgical and 95 (40.2%) microbiological failures. In the multivariate analysis, the risk factors associated with overall failures were documented piperacillin/tazobactam therapy [adjusted OR (aOR) 2.10; 95% CI 1.17-3.75] and renal replacement therapy on the day of reoperation (aOR 2.96; 95% CI 1.05-8.34). The risk factors for death were age (aOR 1.08 per year; 95% CI 1.03-1.12), renal replacement therapy on reoperation (aOR 3.95; 95% CI 1.36-11.49) and diabetes (OR 6.95; 95% CI 1.34-36.03). The risk factors associated with surgical failure were documented piperacillin/tazobactam therapy (aOR 1.99; 95% CI 1.13-3.51), peritoneal cultures containing Klebsiella spp. (aOR 2.45; 95% CI 1.02-5.88) and pancreatic source of infection (aOR 2.91; 95% CI 1.21-7.01). No specific risk factors were identified for microbiological failure. CONCLUSIONS: Our data suggest a predominant role of comorbidities, the severity of post-operative peritonitis and possibly of documented piperacillin/tazobactam treatment on the occurrence of therapeutic failures, regardless of their type.

BACKGROUND AND IMPORTANCE: Hyperoxemia may be associated with increased mortality in emergency room or ICU patients. However, its effect during septic shock is still debated. OBJECTIVE: To evaluate the effect of hyperoxemia on ICU mortality, during the first 24 h of ICU stay, in mechanically ventilated patients with septic shock according to SEPSIS-3 criteria. DESIGN, SETTINGS AND PARTICIPANTS: A retrospective cohort study of ICU admissions recorded in the Medical Information Mart for Intensive Care-III, a retrospective ICU database, was performed. INTERVENTION: Two oxygen exposures during the first 24 h were compared: average PaO2 (TWA-PaO2) between 70 and 120 mmHg in the normoxemia group and above 120 mmHg in the hyperoxemia group. OUTCOME MEASURES AND ANALYSIS: The primary outcome was mortality during ICU stay. MAIN RESULTS: Four hundred eighty-eight ICU admissions met the inclusion criteria: 214 in the normoxemia group and 274 in the hyperoxemia group. The median TWA-PaO2 was 99.1 (88.9-107.6) mmHg in the normoxemia group and 151.5 (133.6-180.2) mmHg in the hyperoxemia group. ICU mortality was lower in the hyperoxemia group than in the normoxemia group in univariate analysis [29.6 vs. 39.7%, respectively; OR 0.64 (0.44-0.93); P = 0.024], but not in multivariate analysis [OR 0.98 (0.62-1.56); P = 0.93]. There was no difference between the two groups in ICU length of stay [8.0 (4.3-15.0) vs. 8.4 (4.7-15.0) days; P = 0.82]. CONCLUSION: We did not find any impact of early hyperoxemia on mortality in this population of mechanically ventilated patients with SEPSIS-3 septic shock criteria.

BACKGROUND: Ventilator-associated pneumonia (VAP) is the most frequent health care-associated infection in severely ill patients, and aspiration of contaminated oropharyngeal content around the cuff of the tracheal tube is the main route of contamination. RESEARCH QUESTION: Is continuous regulation of tracheal cuff pressure using a pneumatic device superior to manual assessment three times daily using a portable manometer (routine care) in preventing VAP in patients with severe trauma? STUDY DESIGN AND METHODS: In this open-label, randomized controlled superiority trial conducted in 13 French ICUs, adults (age ≥ 18 years) with severe trauma (Injury Severity Score > 15) and requiring invasive mechanical ventilation for ≥ 48 h were enrolled. Patients were randomly assigned (1:1) via a secure Web-based random number generator in permuted blocks of variable sizes to one of two groups according to the method of tracheal cuff pressure control. The primary outcome was the proportion of patients developing VAP within 28 days following the tracheal intubation, as determined by two assessors masked to group assignment, in the modified intention-to-treat population. This study is closed to new participants. RESULTS: A total of 434 patients were recruited between July 31, 2015, and February 15, 2018, of whom 216 were assigned to the intervention group and 218 to the control group. Seventy-three patients (33.8%) developed at least one episode of VAP within 28 days following the tracheal intubation in the intervention group compared with 64 patients (29.4%) in the control group (adjusted subdistribution hazard ratio, 0.96; 95% CI, 0.76-1.20; P = .71). No serious adverse events related to the use of the pneumatic device were noted. INTERPRETATION: Continuous regulation of cuff pressure of the tracheal tube using a pneumatic device was not superior to routine care in preventing VAP in patients with severe trauma.
