Perceived Quality of Life in Intensive Care Medicine Physicians: A French National Survey.

Purpose: There is a growing interest in the quality of work life (QWL) of healthcare professionals and staff well-being. We decided to measure the perceived QWL of ICU physicians and the factors that could influence their perception. Methods: We performed a survey coordinated and executed by the French Trade Union of Intensive Care Physicians (SMR). QWL was assessed using the French version of the Work-Related Quality of Life (WRQoL) scale, perceived stress using the French version of 10 item-Perceived Stress Scale (PSS-10) and group functioning using the French version of the Reflexivity Scale, the Social Support at Work Questionnaire (QSSP-P). Results: 308 French-speaking ICU physicians participated. 40% perceived low WRQoL, mainly due to low general well-being, low satisfaction with working conditions and low possibility of managing the articulation between their private and professional lives. Decreased QWL was associated with being a woman (p = .002), having children (p = .022) and enduring many monthly shifts (p = .022). Conclusions: This work highlights the fact that ICU physicians feel a significant imbalance between the demands of their profession and the resources at their disposal. Communication and exchanges within a team and quality of social support appear to be positive elements to maintain and/or develop within our structures.

Fluid balance control in critically ill patients: results from as-treated analyses of POINCARE-2 randomized trial.

BACKGROUND: Intention-to-treat analyses of POINCARE-2 trial led to inconclusive results regarding the effect of a conservative fluid balance strategy on mortality in critically ill patients. The present as-treated analysis aimed to assess the effectiveness of actual exposure to POINCARE-2 strategy on 60-day mortality in critically ill patients. METHODS: POINCARE­2 was a stepped wedge randomized controlled trial. Eligible patients were ≥ 18 years old, under mechanical ventilation and had an expected length of stay in ICU > 24 h. POINCARE-2 strategy consisted of daily weighing over 14 days, and subsequent restriction of fluid intake, administration of diuretics, and/or ultrafiltration. We computed a score of exposure to the strategy based on deviations from the strategy algorithm. We considered patients with a score ≥ 75 as exposed to the strategy. We used logistic regression adjusted for confounders (ALR) or for an instrumental variable (IVLR). We handled missing data using multiple imputations. RESULTS: A total of 1361 patients were included. Overall, 24.8% of patients in the control group and 69.4% of patients in the strategy group had a score of exposure ≥ 75. Exposure to the POINCARE-2 strategy was not associated with 60-day all-cause mortality (ALR: OR 1.2, 95% CI 0.85-1.55; IVLR: OR 1.0, 95% CI 0.76-1.33). CONCLUSION: Actual exposure to POINCARE-2 conservative strategy was not associated with reduced mortality in critically ill patients. Trial registration POINCARE-2 trial is registered at ClinicalTrials.gov (NCT02765009). Registered 29 April 2016.

Valproic acid as adjuvant treatment for convulsive status epilepticus: a randomised clinical trial.

BACKGROUND: Generalised convulsive status epilepticus (GCSE) is a medical emergency. Guidelines recommend a stepwise strategy of benzodiazepines followed by a second-line anti-seizure medicine (ASM). However, GCSE is uncontrolled in 20-40% patients and is associated with protracted hospitalisation, disability, and mortality. The objective was to determine whether valproic acid (VPA) as complementary treatment to the stepwise strategy improves the outcomes of patients with de novo established GCSE. METHODS: This was a multicentre, double-blind, randomised controlled trial in 244 adults admitted to intensive care units for GCSE in 16 French hospitals between 2013 and 2018. Patients received standard care of benzodiazepine and a second-line ASM (except VPA). Intervention patients received a 30 mg/kg VPA loading dose, then a 1 mg/kg/h 12 h infusion, whilst the placebo group received an identical intravenous administration of 0.9% saline as a bolus and continuous infusion. Primary outcome was proportion of patients discharged from hospital by day 15. The secondary outcomes were seizure control, adverse events, and cognition at day 90. RESULTS: A total of 126 (52%) and 118 (48%) patients were included in the VPA and placebo groups. 224 (93%) and 227 (93%) received a first-line and a second-line ASM before VPA or placebo infusion. There was no between-group difference for patients hospital-discharged at day 15 [VPA, 77 (61%) versus placebo, 72 (61%), adjusted relative risk 1.04; 95% confidence interval (0.89-1.19); p = 0.58]. There were no between-group differences for secondary outcomes. CONCLUSIONS: VPA added to the recommended strategy for adult GCSE is well tolerated but did not increase the proportion of patients hospital-discharged by day 15.

Fluid balance control in critically ill patients: results from POINCARE-2 stepped wedge cluster-randomized trial.

BACKGROUND: In critically ill patients, positive fluid balance is associated with excessive mortality. The POINCARE-2 trial aimed to assess the effectiveness of a fluid balance control strategy on mortality in critically ill patients. METHODS: POINCARE-2 was a stepped wedge cluster open-label randomized controlled trial. We recruited critically ill patients in twelve volunteering intensive care units from nine French hospitals. Eligible patients were ≥ 18 years old, under mechanical ventilation, admitted to one of the 12 recruiting units for > 48 and ≤ 72 h, and had an expected length of stay after inclusion > 24 h. Recruitment started on May 2016 and ended on May 2019. Of 10,272 patients screened, 1361 met the inclusion criteria and 1353 completed follow-up. The POINCARE-2 strategy consisted of a daily weight-driven restriction of fluid intake, diuretics administration, and ultrafiltration in case of renal replacement therapy between Day 2 and Day 14 after admission. The primary outcome was 60-day all-cause mortality. We considered intention-to-treat analyses in cluster-randomized analyses (CRA) and in randomized before-and-after analyses (RBAA). RESULTS: A total of 433 (643) patients in the strategy group and 472 (718) in the control group were included in the CRA (RBAA). In the CRA, mean (SD) age was 63.7 (14.1) versus 65.7 (14.3) years, and mean (SD) weight at admission was 78.5 (20.0) versus 79.4 (23.5) kg. A total of 129 (160) patients died in the strategy (control) group. Sixty-day mortality did not differ between groups [30.5%, 95% confidence interval (CI) 26.2-34.8 vs. 33.9%, 95% CI 29.6-38.2, p = 0.26]. Among safety outcomes, only hypernatremia was more frequent in the strategy group (5.3% vs. 2.3%, p = 0.01). The RBAA led to similar results. CONCLUSION: The POINCARE-2 conservative strategy did not reduce mortality in critically ill patients. However, due to open-label and stepped wedge design, intention-to-treat analyses might not reflect actual exposure to this strategy, and further analyses might be required before completely discarding it. Trial registration POINCARE-2 trial was registered at ClinicalTrials.gov (NCT02765009). Registered 29 April 2016.

Post-cardiac arrest myoclonus and in ICU mortality: insights from the Parisian Registry of Cardiac Arrest (PROCAT).

BACKGROUND: Post-cardiac arrest myoclonus (PCAM) is a frequent finding in resuscitated patients after cardiac arrest (CA), with rather poor prognostic significance. In this study, we evaluated the association of PCAM within intensive care unit (ICU) mortality from a university hospital CA patients' registry. METHODS: Clinical data of consecutive CA survivors admitted in the intensive care unit (ICU) between January and December 2016 at the Paris Cochin University Hospital were assessed from the Parisian registry of cardiac arrest (PROCAT) and analyzed. Neurologic outcome was assessed using the Cerebral Performance Categories (CPC) scale at ICU discharge. Prevalence of PCAM and their association with mortality at ICU discharge were computed. RESULTS: One hundred thirty-two (132) patients were included (73.5% males), median age of 66 years. Among them, 37 (28%) developed PCAM during their ICU stay. Only two patients with PCAM survived (5.4%). PCAM was strongly associated with mortality at ICU discharge (odds ratio 17.5 [4.2-123.2]). Sensitivity, specificity, PPV, and NPV of PCAM for prediction of death were 41%, 96%, 95%, and 46%, respectively. CONCLUSION: PCAM was observed in nearly one-third of CA patients admitted in ICU. Patients with PCAM had a significantly higher likelihood of ICU mortality and a low likelihood of a good outcome. The prognostic value of PCAM seems rather bleak but remains nuanced and merits study in larger-scale prospective studies taking into account confounding factors.

Endovascular Versus External Targeted Temperature Management for Patients With Out-of-Hospital Cardiac Arrest: A Randomized, Controlled Study.

BACKGROUND: Targeted temperature management is recommended after out-of-hospital cardiac arrest. Whether advanced internal cooling is superior to basic external cooling remains unknown. The aim of this multicenter, controlled trial was to evaluate the benefit of endovascular versus basic surface cooling. METHODS AND RESULTS: Inclusion criteria were the following: age of 18 to 79 years, out-of-hospital cardiac arrest related to a presumed cardiac cause, time to return of spontaneous circulation <60 minutes, delay between return of spontaneous circulation and inclusion <240 minutes, and unconscious patient after return of spontaneous circulation and before the start of cooling. Exclusion criteria were terminal disease, pregnancy, known coagulopathy, uncontrolled bleeding, temperature on admission <30°C, in-hospital cardiac arrest, immediate need for extracorporeal life support or hemodialysis. Patients were randomized between 2 cooling strategies: endovascular femoral devices (Icy catheter, Coolgard, Zoll, formerly Alsius; n=203) or basic external cooling using fans, a homemade tent, and ice packs (n=197). The primary end point, that is, favorable outcome evaluated by survival without major neurological damage (Cerebral Performance Categories 1-2) at day 28, was not significantly different between groups (odds ratio, 1.41; 95% confidence interval, 0.93-2.16; P=0.107). Improvement in favorable outcome at day 90 in favor of the endovascular group did not reach significance (odds ratio, 1.51; 95% confidence interval, 0.96-2.35; P=0.07). Time to target temperature (33°C) was significantly shorter and target hypothermia was more strictly maintained in the endovascular than in the surface group (P<0.001). Minor side effects directly related to the cooling method were observed more frequently in the endovascular group (P=0.009). CONCLUSION: Despite better hypothermia induction and maintenance, endovascular cooling was not significantly superior to basic external cooling in terms of favorable outcome.

Functional outcome of prolonged refractory status epilepticus.

INTRODUCTION: To characterize etiology, clinical course and outcomes of patients in prolonged refractory status epilepticus (PRSE) and looking for prognostic factors. METHODS: Retrospective study conducted in patients hospitalized from January 1, 2001 to December 31, 2011 in 19 polyvalent intensive care units in French university and general hospitals. Patients were adults with a generalized convulsive refractory status epilepticus that lasted more than seven days, despite treatment including an anesthetic drug and mechanical ventilation. Patients with anoxic encephalopathy were excluded. Follow-up phone call was used to determine functional outcome using modified Rankin Scale (mRS) with mRS 0-3 defining good and mRS 4-6 poor outcome. RESULTS: 78 patients (35 female) were included. Median age was 57 years. Causes of status epilepticus were various, mainly including prior epilepsy (14.1%), CNS infection (12.8%), and stroke (12.8%). No etiology was found in 27 (34.6%) patients. PRSE was considered controlled in only 53 (67.9%) patients after a median duration of 17 (IQR 12-26) days. The median length of ICU stay was 28 (19-48) days. Forty-one (52.5%) patients died in the ICU, 26 from multiple organ failure, 8 from care withdrawal, 2 from sudden cardiac arrest, 1 from brain death and 4 from unknown causes. PRSE was previously resolved in 20 patients who died in the ICU. At one-year follow-up, there were 12 patients with good outcome and 58 with poor outcome and 8 lost of follow-up. On multivariate analysis, only vasopressor use was a predictor of poor outcome (OR 6.54; 95%CI 1.09-39.29; p = 0.04). CONCLUSION: Poor outcome was observed in about 80% of this population of PRSE. Most patients died from systemic complications linked to their ICU stay. Some patients can recover satisfactorily over time though we did not identify any robust factor of good outcome.

Effects of fluid resuscitation with colloids vs crystalloids on mortality in critically ill patients presenting with hypovolemic shock: the CRISTAL randomized trial.

IMPORTANCE: Evidence supporting the choice of intravenous colloid vs crystalloid solutions for management of hypovolemic shock remains unclear. OBJECTIVE: To test whether use of colloids compared with crystalloids for fluid resuscitation alters mortality in patients admitted to the intensive care unit (ICU) with hypovolemic shock. DESIGN, SETTING, AND PARTICIPANTS: A multicenter, randomized clinical trial stratified by case mix (sepsis, trauma, or hypovolemic shock without sepsis or trauma). Therapy in the Colloids Versus Crystalloids for the Resuscitation of the Critically Ill (CRISTAL) trial was open label but outcome assessment was blinded to treatment assignment. Recruitment began in February 2003 and ended in August 2012 of 2857 sequential ICU patients treated at 57 ICUs in France, Belgium, North Africa, and Canada; follow-up ended in November 2012. INTERVENTIONS: Colloids (n = 1414; gelatins, dextrans, hydroxyethyl starches, or 4% or 20% of albumin) or crystalloids (n = 1443; isotonic or hypertonic saline or Ringer lactate solution) for all fluid interventions other than fluid maintenance throughout the ICU stay. MAIN OUTCOMES AND MEASURES: The primary outcome was death within 28 days. Secondary outcomes included 90-day mortality; and days alive and not receiving renal replacement therapy, mechanical ventilation, or vasopressor therapy. RESULTS: Within 28 days, there were 359 deaths (25.4%) in colloids group vs 390 deaths (27.0%) in crystalloids group (relative risk [RR], 0.96 [95% CI, 0.88 to 1.04]; P = .26). Within 90 days, there were 434 deaths (30.7%) in colloids group vs 493 deaths (34.2%) in crystalloids group (RR, 0.92 [95% CI, 0.86 to 0.99]; P = .03). Renal replacement therapy was used in 156 (11.0%) in colloids group vs 181 (12.5%) in crystalloids group (RR, 0.93 [95% CI, 0.83 to 1.03]; P = .19). There were more days alive without mechanical ventilation in the colloids group vs the crystalloids group by 7 days (mean: 2.1 vs 1.8 days, respectively; mean difference, 0.30 [95% CI, 0.09 to 0.48] days; P = .01) and by 28 days (mean: 14.6 vs 13.5 days; mean difference, 1.10 [95% CI, 0.14 to 2.06] days; P = .01) and alive without vasopressor therapy by 7 days (mean: 5.0 vs 4.7 days; mean difference, 0.30 [95% CI, -0.03 to 0.50] days; P = .04) and by 28 days (mean: 16.2 vs 15.2 days; mean difference, 1.04 [95% CI, -0.04 to 2.10] days; P = .03). CONCLUSIONS AND RELEVANCE: Among ICU patients with hypovolemia, the use of colloids vs crystalloids did not result in a significant difference in 28-day mortality. Although 90-day mortality was lower among patients receiving colloids, this finding should be considered exploratory and requires further study before reaching conclusions about efficacy.

Risk Factors of AKI in Acute Respiratory Distress Syndrome: A Time-Dependent Competing Risk Analysis on Severe COVID-19 Patients.

Introduction: Acute kidney injury (AKI) is frequently observed in patients with COVID-19 admitted to intensive care units (ICUs). Observational studies suggest that cardiovascular comorbidities and mechanical ventilation (MV) are the most important risk factors for AKI. However, no studies have investigated the renal impact of longitudinal covariates such as drug treatments, biological variations, and/or MV parameters. Methods: We performed a monocentric, prospective, longitudinal analysis to identify the dynamic risk factors for AKI in ICU patients with severe COVID-19. Results: Seventy-seven patients were included in our study (median age: 63 [interquartile range, IQR: 53-73] years; 58 (75%) men). Acute kidney injury was detected in 28 (36.3%) patients and occurred at a median time of 3 [IQR: 2-6] days after ICU admission. Multivariate Cox cause-specific time-dependent analysis identified a history of hypertension (cause-specific hazard (CSH) = 2.46 [95% confidence interval, CI: 1.04-5.84]; P = .04), a high hemodynamic Sequential Organ Failure Assessment score (CSH = 1.63 [95% CI: 1.23-2.16]; P < .001), and elevated Paco2 (CSH = 1.2 [95%CI: 1.04-1.39] per 5 mm Hg increase in Pco2; P = .02) as independent risk factors for AKI. Concerning the MV parameters, positive end-expiratory pressure (CSH = 1.11 [95% CI: 1.01-1.23] per 1 cm H2O increase; P = .04) and the use of neuromuscular blockade (CSH = 2.96 [95% CI: 1.22-7.18]; P = .02) were associated with renal outcome only in univariate analysis but not after adjustment. Conclusion: Acute kidney injury is frequent in patients with severe COVID-19 and is associated with a history of hypertension, the presence of hemodynamic failure, and increased Pco2. Further studies are necessary to evaluate the impact of hypercapnia on increasing the effects of ischemia, particularly in the most at-risk vascular situations.

Introduction: L'insuffisance rénale aiguë (IRA) est fréquemment observée chez les patients atteints de COVID-19 admis dans les unités de soins intensifs (USI). Des études observationnelles suggèrent que les comorbidités cardiovasculaires et la ventilation mécanique (VM) seraient les plus importants facteurs de risque de l'IRA. Aucune étude n'a cependant examiné l'impact sur la fonction rénale de covariables longitudinales telles que les traitements médicamenteux, les variations biologiques et/ou les paramètres de la VM. Méthodologie: Nous avons procédé à une analyse prospective et longitudinale dans un seul centre hospitalier afin d'identifier les facteurs de risque dynamiques de l'IRA chez les patients hospitalisés aux USI en raison d'une forme grave de la COVID-19. Résultats: Soixante-dix-sept patients ont été inclus dans notre étude (75 % d'hommes [n=58]; âge médian: 63 ans [ÉIQ: 53-73]). L'IRA a été détectée chez 28 patients (36,3 %) et est survenue dans un délai médian de 3 jours (ÉIQ: 2-6 jours) après l'admission à l'USI. Une analyse de Cox multivariée, spécifique à la cause et tenant compte du temps, a permis de dégager les éléments suivants comme étant des facteurs de risque indépendants pour l'IRA: des antécédents d'hypertension (probabilité par cause [PPC]=2,46 [IC 95 %: 1,04-5,84]; p=0,04), un score SOFA hémodynamique élevé (PPC=1,63 [IC 95 %: 1,23-2,16]; p<0,001) et une concentration élevée de PaCO2 (PPC=1,2 [IC 95 %: 1,04-1,39] pour chaque augmentation de 5 mmHg de pCO2; p = 0,02). En ce qui concerne les paramètres de la VM, une pression expiratoire positive (PPC=1,11 [IC 95 %: 1,01-1,23] pour chaque augmentation de 1 cm H2O; p = 0,04) et l'utilisation d'un bloc neuromusculaire (PPC=2,96 [IC 95 %: 1,22-7,18]; p=0,02) ont été associés à l'IRA dans l'analyse univariée seulement, et non après ajustement. Conclusion: L'IRA est fréquente chez les patients atteints d'une forme grave de COVID-19 et elle est associé à des antécédents d'hypertension, à la présence d'une instabilité hémodynamique et à une augmentation de la pCO2. D'autres études sont nécessaires pour évaluer l'impact de l'hypercapnie sur l'augmentation des effets de l'ischémie, en particulier dans les situations vasculaires les plus à risque.

Hormonal status in protracted critical illness and in-hospital mortality.

INTRODUCTION: The aim of this study was to determine the relationship between hormonal status and mortality in patients with protracted critical illness. METHODS: We conducted a prospective observational study in four medical and surgical intensive care units (ICUs). ICU patients who regained consciousness after 7 days of mechanical ventilation were included. Plasma levels of insulin-like growth factor 1 (IGF-1), prolactin, thyroid-stimulating hormone, follicle-stimulating hormone, luteinizing hormone, estradiol, progesterone, testosterone, dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEAS) and cortisol were measured on the first day patients were awake and cooperative (day 1). Mean blood glucose from admission to day 1 was calculated. RESULTS: We studied 102 patients: 65 men and 37 women (29 of the women were postmenopausal). Twenty-four patients (24%) died in the hospital. The IGF-1 levels were higher and the cortisol levels were lower in survivors. Mean blood glucose was lower in women who survived, and DHEA and DHEAS were higher in men who survived. CONCLUSIONS: These results suggest that, on the basis of sex, some endocrine or metabolic markers measured in the postacute phase of critical illness might have a prognostic value.

Intermittent subglottic secretion drainage and ventilator-associated pneumonia: a multicenter trial.

RATIONALE: Ventilator-associated pneumonia (VAP) causes substantial morbidity and mortality. The influence of subglottic secretion drainage (SSD) in preventing VAP remains controversial. OBJECTIVES: To determine whether SSD reduces the overall incidence of microbiologically confirmed VAP. METHODS: Randomized controlled clinical trial conducted at four French centers. A total of 333 adult patients intubated with a tracheal tube allowing drainage of subglottic secretions and expected to require mechanical ventilation for ≥48 hours was included. Patients were randomly assigned to undergo intermittent SSD (n = 169) or not (n = 164). MEASUREMENTS AND MAIN RESULTS: Primary outcome was the overall incidence of VAP based on quantitative culture of distal pulmonary samplings performed after each clinical suspicion. Other outcomes included incidence of early- and late-onset VAP, duration of mechanical ventilation, and hospital mortality. Microbiologically confirmed VAP occurred in 67 patients, 25 of 169 (14.8%) in the SSD group and 42 of 164 (25.6%) in the control group (P = 0.02), yielding a relative risk reduction of 42.2% (95% confidential interval, 10.4-63.1%). Using the Day 5 threshold, the beneficial effect of SSD in reducing VAP was observed in both early-onset VAP (2 of 169 [1.2%] patients undergoing SSD vs. 10 of 164 [6.1%] control patients; P = 0.02) and late-onset VAP (23 of 126 [18.6%] patients undergoing SSD vs. 32 of 97 [33.0%] control patients; P = 0.01). VAP was clinically suspected at least once in 51 of 169 (30.2%) patients undergoing SSD and 60 of 164 (36.6%) control patients (P = 0.25). No significant between-group differences were observed in duration of mechanical ventilation and hospital mortality. CONCLUSIONS: Subglottic secretion drainage during mechanical ventilation results in a significant reduction in VAP, including late-onset VAP. Clinical trial registered with www.clinicaltrials.gov (NCT00219661).

Not all patients with convulsive status epilepticus intubated in pre-hospital settings meet the criteria for refractory status epilepticus.

INTRODUCTION: Mechanically ventilated patients admitted to the intensive care unit (ICU) for generalized convulsive status epilepticus (GCSE) are a heterogeneous population. Our objective was to evaluate the number of patients who fulfilled the diagnostic criteria for refractory GCSE and describe their initial management and prognosis. METHODS: This multicenter retrospective study was conducted in four French ICUs in Pitié-Salpêtrière University Hospital in Paris and in the Hospital of Jossigny. Mechanically ventilated patients admitted to the ICU for GCSE between, January 1, 2014, and, December 31, 2016, were included. Patients with anoxia and traumatic brain injury were excluded. Their pre-hospital and ICU medical records were reviewed. The collected data included pre-hospital clinical status, pre-hospital antiepileptic treatment, reason for mechanical ventilation, duration of general anesthesia, and prognosis in the ICU. A retrospective initial diagnosis based on the findings of the analysis of the clinical records was attributed to each patient. RESULTS: Among the 98 patients included, 88.8% (n = 87/98) fulfilled the diagnostic criteria for GCSE; of these cases, 16.1% (n = 14/87) were refractory. Eleven percent of the patients did not fulfill the criteria for GCSE at the time of initial management (retrospective diagnosis of single convulsive seizure, repetitive convulsive seizures, or psychogenic non-epileptic seizures). Most patients were intubated for coma (58.9%, n = 56/95, missing data: n = 3). In the ICU, the median [Q1-Q3] duration of general anesthesia before weaning was 12.3 h (5.0-18.0 h); 7% of the patients had a relapse of status epilepticus, and 2% died in the ICU. CONCLUSION: Among the cases of confirmed GCSE in the mechanically ventilated patients admitted to the ICU, 16.1% were refractory, with an overall good prognosis. A significant proportion of patients did not fulfill the diagnostic criteria for refractory GCSE.

Valproic Acid as an Adjuvant Treatment for Generalized Convulsive Status Epilepticus in Adults Admitted to Intensive Care Units: Protocol for a Double-Blind, Multicenter Randomized Controlled Trial.

BACKGROUND: Generalized convulsive status epilepticus (GCSE) is a frequent medical emergency. GCSE treatment focuses on the administration of benzodiazepines followed by a second-line antiepileptic drug (AED). Despite this stepwise strategy, GCSE is not controlled in one-quarter of patients and is associated with protracted hospitalization, high mortality, and long-term disability. Valproic acid (VPA) is an AED with good tolerability and neuroprotective properties. OBJECTIVE: This study aims to demonstrate that administration of VPA as an adjuvant for first- and second-line treatment in GCSE can improve outcomes. METHODS: A multicenter, double-blind, randomized controlled trial was conducted, comparing VPA with a placebo in adults admitted to intensive care units (ICUs) for GCSE in France. GCSE was diagnosed by specifically trained ICU physicians according to standard criteria. All patients received standard of care, including a benzodiazepine and a second-line AED (not VPA), at the discretion of the treating medical team. In the intervention arm, VPA was administered intravenously at a loading dose of 30 mg/kg over 15 minutes, followed by a continuous infusion of 1 mg/kg/hour over the next 12 hours. In the placebo group, an identical intravenous administration of 0.9% saline was used. The primary outcome was the proportion of patients discharged alive from the hospital by day 15. Secondary outcomes were frequency of refractory and super refractory GCSE, ICU-related morbidity, adverse events related to VPA, and cognitive dysfunction at 3 months. Statistical analyses will be performed according to the intent-to-treat principle. RESULTS: The first patient was randomized on February 18, 2013, and the last patient was randomized on July 7, 2018. Of 248 planned patients, 98.7% (245/248) were enrolled across 20 ICUs. At present, data management is still ongoing, and all parties involved in the trial remain blinded. CONCLUSIONS: The Valproic Acid as an Adjuvant Treatment for Generalized Convulsive Status Epilepticus (VALSE) trial will evaluate whether the use of VPA as an adjuvant for first- and second-line treatment in GCSE improves outcomes.

Immune thrombocytopenia in a patient with COVID-19.

This case report describes immune thrombocytopenic purpura in a 41-year-old man hospitalized in the intensive-care unit for COVID-19, 13 days after the onset of COVID-19 symptoms with respiratory failure at admission. Acute respiratory distress syndrome was treated with, among other drugs, low-molecular-weight heparin. On day 8, his platelet count began descending rapidly. On day 10, heparin treatment was replaced by danaparoid sodium, but by day 13, the continued low platelet count made a diagnosis of heparin-induced thrombocytopenia unlikely. Normocytic nonregenerative anemia gradually developed. On day 13, a bone marrow aspiration showed numerous megakaryocytes and a few signs of hemophagocytosis. Corticosteroids were introduced on day 14, and platelets began rising after 3 days and then fell again on day 19. Intravenous immunoglobulin (IV Ig) was then administered. Two days later, the platelet count returned to normal. The immune cause was confirmed by ruling out the differential diagnoses and the excellent and rapid response to intravenous immunoglobulins. Finally, the patient's respiratory state improved. He was discharged to a respiratory rehabilitation unit on day 38. Our case suggests that an immunological cause should be considered in patients with thrombocytopenia during COVID-19.

Intensive care unit-acquired weakness: risk factors and prevention.

Intensive care unit-acquired weakness, the main clinical sign of critical illness neuromyopathy, is an increasingly recognized cause of prolonged mechanical ventilation and delayed return to physical self-sufficiency. Identifying risk factors and developing preventive measures are therefore important goals. Several studies on risk factors for critical illness neuromyopathy including prospective observational studies with a multivariate analysis of potential risk factors were conducted over the last decade. A large body of data is also available from two large prospective randomized trials comparing the effect of strict vs. conventional blood-glucose control on intensive care unit mortality and on secondary outcomes including the occurrence of critical illness neuromyopathy. Five central risk factors and their related potential measures to prevent intensive care unit-acquired weakness can be identified including multiple organ failure, muscle inactivity, hyperglycemia, and use of corticosteroids and neuromuscular blockers. Although strong evidence regarding the efficacy of preventive measures is still lacking, the results of available studies are promising and cast doubt on the widespread belief that the treatment of intensive care unit-acquired weakness is essentially supportive. Early identifying and treating conditions leading to multiple organ failure, especially severe sepsis and septic shock, avoiding unnecessary deep sedation and excessive blood glucose levels, promoting early mobilization, and carefully weighing the risks and benefits of corticosteroids might contribute to reduce the incidence and severity of intensive care unit-acquired weakness.

Presence and severity of intensive care unit-acquired paresis at time of awakening are associated with increased intensive care unit and hospital mortality.

OBJECTIVES: To assess whether the presence and severity of intensive care unit-acquired paresis are associated with intensive care unit and in-hospital mortality. DESIGN: Prospective, observational study. SETTING: Two medical, one surgical, and one medico-surgical intensive care units in two university hospitals and one university-affiliated hospital. PATIENTS: A total of 115 consecutive patients were enrolled after > 7 days of mechanical ventilation. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The Medical Research Council score (from 0-60) was used to evaluate upper and lower limb strength at time of awakening, identified as the ability to follow five commands. Intensive care unit-acquired paresis was defined as a Medical Research Council score <48. Patients were followed-up until hospital discharge. The primary end point was hospital mortality. At awakening, median Medical Research Council score was 41 (interquartile range, 21-52), and 75 (65%) patients had intensive care unit-acquired paresis. Hospital non-survivors had a significantly lower Medical Research Council score at awakening (21 [11-43]) vs. 41 [28-53]; p = .008) and a significantly higher rate of intensive care unit-acquired paresis (85.1% vs. 58.4%; p = .02) compared to survivors. After multivariate risk adjustment, intensive care unit-acquired paresis was independently associated with higher hospital and intensive care unit mortality (odds ratio for hospital mortality, 2.02; 95% confidence interval, 1.03-8.03; p = .048). Each Medical Research Council point decrease was associated with a significantly higher hospital mortality (odds ratio, 1.03; 95% confidence interval, 1.01-1.05; p = .033). CONCLUSIONS: Both the presence and severity of intensive care unit-acquired paresis at the time of awakening are associated with increased intensive care unit and hospital mortality; the mechanisms underlying this association need further study.

Staged laparoscopic adjuvant intraperitoneal chemohyperthermia after complete resection for locally advanced colorectal or gastric cancer: a preliminary experience.

BACKGROUND: Cytoreductive surgery followed by intraperitoneal chemohyperthermia (IPCH) is a promising treatment for patients with peritoneal carcinomatosis, a disease with dismal prognosis. METHODS: We describe our preliminary experience with staged adjuvant laparoscopic IPCH after complete resection in patients with locally or regionally advanced colorectal or gastric cancer. RESULTS: Twenty-one patients underwent resection for colorectal (N = 16) or gastric cancer (N = 5) followed by staged laparoscopic IPCH. No conversion to laparotomy was required. No major operative incident occurred. Mean duration of hospital stay was 12 days (range 9-23 days). No mortality occurred in the 30-day postoperative period. Four patients developed major complications (19%). One patient (5%) was reoperated. Mean follow-up period was 15.5 months (range 9-29 months). Three patients died, including two of cancer-related causes. No patient developed peritoneal carcinomatosis during the follow-up period. CONCLUSION: Staged laparoscopic adjuvant IPCH after open or laparoscopic resection in selected patients with colorectal or gastric cancer is feasible and reasonably safe. However, additional data are required to determine the effect on long-term survival.

Update in Neurocritical Care: a summary of the 2018 Paris international conference of the French Society of Intensive Care.

The 2018 Paris Intensive Care symposium entitled "Update in Neurocritical Care" was organized in Paris, June 21-22, 2018, under the auspices of the French Intensive Care Society. This 2-day post-graduate educational symposium comprised several chapters, aiming first to provide all-board intensivists with current standards for the clinical assessment of altered consciousness states (including coma and delirium) and peripheral nervous system in critically ill patients, monitoring of brain function (specifically, electro-encephalography) and best practices for sedation-analgesia-delirium management. An update on the treatment of specific severe brain pathologies-including ischaemic/haemorrhagic stroke, cerebral venous thrombosis, hypoxic-ischaemic brain injury, immune-mediated and infectious encephalitis and refractory status epilepticus-was also provided. Finally, we discuss how to approach some difficult decisions, namely the role of decompressive craniectomy and prognostication models in patients with head injury. For each chapter, the scope of the present review was to provide important issues and key messages, provide most recent and relevant literature in the field, and briefly describe new developments in the field.
