Giving a voice to patients at high risk of dying in the intensive care unit: a multiple source approach.

PURPOSE: Data are scarce regarding the experience of critically ill patients at high risk of death. Identifying their concerns could allow clinicians to better meet their needs and align their end-of-life trajectory with their preferences and values. We aimed to identify concerns expressed by conscious patients at high risk of dying in the intensive care unit (ICU). METHODS: Multiple source multicentre study. Concerns expressed by patients were collected from five different sources (literature review, panel of 50 ICU experts, prospective study in 11 ICUs, in-depth interviews with 17 families and 15 patients). All qualitative data collected were analyzed using thematic content analysis. RESULTS: The five sources produced 1307 concerns that were divided into 7 domains and 41 sub-domains. After removing redundant items and duplicates, and combining and reformulating similar items, 28 concerns were extracted from the analysis of the data. To increase accuracy, they were merged and consolidated, and resulted in a final list of 15 concerns pertaining to seven domains: concerns about loved-ones; symptom management and care (including team competence, goals of care discussions); spiritual, religious, and existential preoccupations (including regrets, meaning, hope and trust); being oneself (including fear of isolation and of being a burden, absence of hope, and personhood); the need for comforting experiences and pleasure; dying and death (covering emotional and practical concerns); and after death preoccupations. CONCLUSION: This list of 15 concerns may prove valuable for clinicians as a tool for improving communication and support to better meet the needs of patients at high risk of dying.

Unchanged Characteristics and Survival among Critically Ill COVID-19 Patients during First, Second, and Third Waves: A Prospective Observational Cohort.

BACKGROUND: This study was carried out to compare characteristics and outcomes in patients with acute respiratory failure related to COVID-19 during first, second, and third waves. METHODS: We included consecutive adults admitted to the intensive care unit between March 2020 and July 2021. We compared three groups defined by the epidemic intake phase: waves 1 (W1), 2 (W2), and 3 (W3). RESULTS: We included 289 patients. Two hundred and eight (72%) patients were men with a median age of 63 years (IQR: 54-72), of whom 68 (23.6%) died in hospital. High-flow nasal oxygen (HFNO) was inversely associated with the need for invasive mechanical ventilation (MV) in multivariate analysis (p = 0.003) but not dexamethasone (p = 0.25). The day-90 mortality rate did not vary from W1 (27.4%) to W2 (23.9%) and W3 (22%), p = 0.67. By multivariate analysis, older age (odds ratio [OR]: 0.94/year, p < 0.001), immunodeficiency (OR: 0.33, p = 0.04), acute kidney injury (OR: 0.26, p < 0.001), and invasive MV (OR: 0.13, p < 0.001) were inversely associated with higher day-90 survival as opposed to the use of intermediate heparin thromboprophylaxis dose (OR: 3.21, p = 0.006). HFNO use and dexamethasone were not associated with higher day-90 survival (p = 0.24 and p = 0.56, respectively). CONCLUSIONS: In patients with acute respiratory failure due to COVID-19, survival did not change between first, second, and third waves while the use of invasive MV decreased. HFNO or intravenous steroids were not associated with better outcomes, whereas the use of intermediate dose of heparin for thromboprophylaxis was associated with higher day-90 survival. Larger multicentric studies are needed to confirm our findings.

Management and outcomes of critically ill adult patients with convulsive status epilepticus and preadmission functional impairments.

OBJECTIVE: Functional status is among the criteria relevant to decisions about intensive care unit (ICU) admission and level of care. Our main objective was to describe the characteristics and outcomes of adult patients requiring ICU admission for Convulsive Status Epilepticus (CSE) according to whether their functional status was previously impaired. METHODS: We retrospectively analyzed data from consecutive adults who were admitted to two French ICUs for CSE between 2005 and 2018 and then included them retrospectively in the Ictal Registry. Pre-existing functional impairment was defined as a Glasgow Outcome Scale (GOS) score of 3 before admission. The primary outcome measure was a loss of ≥1 GOS score point at 1 year. Multivariate analysis was used to identify factors associated with this measure. RESULTS: The 206 women and 293 men had a median age of 59 years [47-70 years]. The preadmission GOS score was 3 in 56 (11.2%) patients and 4 or 5 in 443 patients. Compared to the GOS-4/5 group, the GOS-3 group was characterized by a higher frequency of treatment-limitation decisions (35.7% vs. 12%, P < 0.0001), similar ICU mortality (19.6 vs. 13.1, P = 0.22), higher 1-year mortality (39.3% vs. 25.6%, P < 0.01), and a similar proportion of patients with no worsening of the GOS score at 1 year (42.9 vs. 44.1, P = 0.89). By multivariate analysis, not achieving a favorable 1-year outcome was associated with age above 59 years (OR, 2.36; 95%CI, 1.55-3.58, P < 0.0001), preexisting ultimately fatal comorbidity (OR, 2.92; 95%CI, 1.71-4.98, P = 0.0001), refractory CSE (OR, 2.19; 95%CI, 1.43-3.36, P = 0.0004), cerebral insult as the cause of CSE (OR, 2.75; 95%CI, 1.75-4.27, P < 0.0001), and Logistic Organ Dysfunction score ≥ 3 at ICU admission (OR, 2.08; 95%CI, 1.37-3.15, P = 0.0006). A preadmission GOS score of 3 was not associated with a functional decline during the first year (OR, 0.61; 95%CI, 0.31-1.22, P = 0.17). SIGNIFICANCE: Preadmission functional status in adult patients with CSE is not independently associated with a functional decline during the first postadmission year. This finding may help physicians make ICU admission decisions and adult patients write advance directives. STUDY REGISTRATION: #NCT03457831.

Natraemia variations induced by acute dialysis in critically ill patients: a database study.

Natraemia is often abnormal in critically ill patients and may change rapidly during renal replacement therapy (RRT). This database study in a single intensive care unit (ICU) evaluated natraemia before and after the first RRT session for acute kidney injury. Of 252 patients who required RRT in 2018-2020, 215 were included. Prevalences were 53.9% for hyponatraemia (≤ 135 mmol/L) and 3.7% for hypernatraemia (> 145 mmol/L). Dialysate sodium was ≥ 145 mmol/L in 83% of patients. Median dialysis sodium gradient was 12 mmol/L, with a value above 16 mmol/L in 25% of patients. Median natraemia increased from 135 before to 140 mmol/L after RRT, the median hourly increase being faster than recommended, at 1.0 mmol/L [0.2-1.7]. By multivariate analysis, the only variable significantly associated with the RRT-induced natraemia change was the dialysis sodium gradient [odds ratio, 1.66; 95% confidence interval 1.39-2.10]. Pearson's correlation coefficient between the gradient and the natraemia change was 0.57. When performing RRT in ICU patients, in addition to the haemodynamic considerations put forward in recommendations, the dialysis sodium gradient deserves careful attention in order to control natraemia variations. Studies to devise a formula for predicting natraemia variations might prove helpful to confirm our results.

Cerebrospinal fluid features in comatose survivors of cardiac arrest: A pilot study.

INTRODUCTION: Lumbar puncture is among the investigations used to identify various neurological conditions, including some that can cause cardiac arrest (CA). However, CA per se may alter cerebrospinal fluid (CSF) characteristics. Few studies have investigated CSF findings after CA. In this descriptive work, we assessed the frequency and risk factors of abnormal CSF findings after CA and the contribution of CSF analysis to the etiological diagnosis. MATERIALS AND METHODS: We retrospectively studied data from prospectively established databases of consecutive patients who were admitted to two French ICUs in 2007-2016 with sustained return of spontaneous circulation (ROSC) after CA and who underwent lumbar puncture as an etiological investigation. RESULTS: Of 1984 patients with sustained ROSC, 55 (2.7%) underwent lumbar puncture and were included. Lumbar puncture identified a neurological cause of CA in 2/55 (3.6%) patients. Nonspecific CSF abnormalities were noted in 37/53 (69.8%) patients. By multivariate analysis, postresuscitation shock was positively associated with CSF abnormalities (OR, 6.92; 95% confidence interval [95%CI], 1.62-37.26; P = 0.013). A no-flow time above 6 minutes (OR, 0.19; 95%CI, 0.03-1.11; P = 0.076) and a respiratory cause of CA (OR, 2.91; 95%CI, 0.53-23.15; P = 0.24) were not statistically associated with CSF abnormalities. Nonspecific CSF abnormalities were not significantly associated with poor outcomes (Cerebral Performance Category ≥3; P = 0.06). CONCLUSIONS: Lumbar puncture, although infrequently performed, may contribute to the etiological diagnosis of CA, albeit rarely. Nonspecific CSF abnormalities seem common after CA, notably with postresuscitation shock, and may be related to blood-brain barrier disruption. These findings may help to interpret CSF findings after CA. Further studies are warranted to assess our results.

Neurologic outcome of VZV encephalitis one year after ICU admission: a multicenter cohort study.

BACKGROUND: Varicella-zoster virus (VZV) is one of the main viruses responsible of acute encephalitis. However, data on the prognosis and neurologic outcome of critically ill patients with VZV encephalitis are limited. We aimed to describe the clinical features of VZV encephalitis in the ICU and to identify factors associated with a favorable neurologic outcome. We performed a multicenter cohort study of patients with VZV encephalitis admitted in 18 ICUs in France between 2000 and 2017. Factors associated with a favorable neurologic outcome, defined by a modified Rankin Score (mRS) of 0-2 1 year after ICU admission, were identified by multivariable regression analysis. RESULTS: Fifty-five patients (29 (53%) men, median age 53 (interquartile range 36-66)) were included, of whom 43 (78%) were immunocompromised. ICU admission occurred 1 (0-3) day after the onset of neurological symptoms. Median Glasgow Coma Score at ICU admission was 12 (7-14). Cerebrospinal fluid examination displayed a median leukocyte count of 68 (13-129)/mm3, and a median protein level of 1.37 (0.77-3.67) g/L. CT scan and MRI revealed brain lesions in 30% and 66% of the cases, respectively. Invasive mechanical ventilation was implemented in 46 (84%) patients for a median duration of 13 (3-30) days. Fourteen (25%) patients died in the ICU. One year after ICU admission, 20 (36%) patients had a favorable neurologic outcome (mRS 0-2), 12 (22%) had significant disability (mRS 3-5), and 18 (33%) were deceased (lost to follow-up n = 5, 9%). On multivariable analysis, age (OR 0.92 per year, (0.88-0.97), p = 0.01), and invasive mechanical ventilation (OR 0.09 CI 95% (0.01-0.84), p = 0.03) reduced the likelihood of favorable neurologic outcome. CONCLUSION: One in every three critically ill patients with VZV encephalitis had a favorable neurologic outcome 1 year after ICU admission. Older age and invasive mechanical ventilation were associated with a higher risk of disability and death.

Association of ventilator type with hospital mortality in critically ill patients with SARS-CoV2 infection: a prospective study.

BACKGROUND: To evaluate the association between ventilator type and hospital mortality in patients with acute respiratory distress syndrome (ARDS) related to COVID-19 (SARS-CoV2 infection), a single-center prospective observational study in France. RESULTS: We prospectively included consecutive adults admitted to the intensive care unit (ICU) of a university-affiliated tertiary hospital for ARDS related to proven COVID-19, between March 2020 and July 2021. All patients were intubated. We compared two patient groups defined by whether an ICU ventilator or a less sophisticated ventilator such as a sophisticated turbine-based transport ventilator was used. Kaplan-Meier survival curves were plotted. Cox multivariate regression was performed to identify associations between patient characteristics and hospital mortality. We included 189 patients (140 [74.1%] men) with a median age of 65 years [IQR, 55-73], of whom 61 (32.3%) died before hospital discharge. By multivariate analysis, factors associated with in-hospital mortality were age ≥ 70 years (HR, 2.11; 95% CI, 1.24-3.59; P = 0.006), immunodeficiency (HR, 2.43; 95% CI, 1.16-5.09; P = 0.02) and serum creatinine ≥ 100 µmol/L (HR, 3.01; 95% CI, 1.77-5.10; P < 0.001) but not ventilator type. As compared to conventional ICU (equipped with ICU and anesthesiology ventilators), management in transient ICU (equipped with non-ICU turbine-based ventilators) was associated neither with a longer duration of invasive mechanical ventilation (18 [IQR, 11-32] vs. 21 [13-37] days, respectively; P = 0.39) nor with a longer ICU stay (24 [IQR, 14-40] vs. 27 [15-44] days, respectively; P = 0.44). CONCLUSIONS: In ventilated patients with ARDS due to COVID-19, management in transient ICU equipped with non-ICU sophisticated turbine-based ventilators was not associated with worse outcomes compared to standard ICU, equipped with ICU ventilators. Although our study design is not powered to demonstrate any difference in outcome, our results after adjustment do not suggest any signal of harm when using these transport type ventilators as an alternative to ICU ventilators during COVID-19 surge.

A three-step support strategy for relatives of patients dying in the intensive care unit: a cluster randomised trial.

BACKGROUND: In relatives of patients dying in intensive care units (ICUs), inadequate team support can increase the prevalence of prolonged grief and other psychological harm. We aimed to evaluate whether a proactive communication and support intervention would improve relatives' outcomes. METHODS: We undertook a prospective, multicentre, cluster randomised controlled trial in 34 ICUs in France, to compare standard care with a physician-driven, nurse-aided, three-step support strategy for families throughout the dying process, following a decision to withdraw or withhold life support. Inclusion criteria were relatives of patients older than 18 years with an ICU length of stay 2 days or longer. Participating ICUs were randomly assigned (1:1 ratio) into an intervention cluster and a control cluster. The randomisation scheme was generated centrally by a statistician not otherwise involved in the study, using permutation blocks of non-released size. In the intervention group, three meetings were held with relatives: a family conference to prepare the relatives for the imminent death, an ICU-room visit to provide active support, and a meeting after the patient's death to offer condolences and closure. ICUs randomly assigned to the control group applied their best standard of care in terms of support and communication with relatives of dying patients. The primary endpoint was the proportion of relatives with prolonged grief (measured with PG-13, score ≥30) 6 months after the death. Analysis was by intention to treat, with the bereaved relatives as the unit of observation. The study is registered with ClinicalTrials.gov, NCT02955992. FINDINGS: Between Feb 23, 2017, and Oct 8, 2019, we enrolled 484 relatives of ICU patients to the intervention group and 391 to the control group. 379 (78%) relatives in the intervention group and 309 (79%) in the control group completed the 6-month interview to measure the primary endpoint. The intervention significantly reduced the number of relatives with prolonged grief symptoms (66 [21%] vs 57 [15%]; p=0·035) and the median PG-13 score was significantly lower in the intervention group than in the control group (19 [IQR 14-26] vs 21 [15-29], mean difference 2·5, 95% CI 1·04-3·95). INTERPRETATION: Among relatives of patients dying in the ICU, a physician-driven, nurse-aided, three-step support strategy significantly reduced prolonged grief symptoms.

Ventilator-associated pneumonia due to Stenotrophomonas maltophilia: Risk factors and outcome.

BACKGROUND: Stenotrophomonas maltophilia (SM) is increasingly identified in intensive care unit (ICU). This study aim to identify risk factors for SM ventilator-associated pneumonia (VAP) and whether it affects ICU mortality METHODS: Two nested matched case-control studies were performed based in OUTCOMEREA database. The first episodes of SM-VAP patients were matched with two different control groups: VAP due to other micro-organisms (VAP-other) and Pseudomonas aeruginosa VAP (Pyo-VAP). Matching criteria were the hospital, the SAPS II, and the previous duration of mechanical ventilation (MV). RESULTS: Of the 102 SM-VAP patients (6.2% of all VAP patients), 92 were matched with 375 controls for the SM-VAP/other-VAP matching and 84 with 237 controls for the SM-VAP/Pyo-VAP matching. SM-VAP risk factors were an exposition to ureido/carboxypenicillin or carbapenem during the week before VAP, and respiratory and coagulation components of SOFA score upper to 2 before VAP. SM-VAP received early adequate therapy in 70 cases (68.6%). Risk factors for Day-30 were age (OR = 1.03; p < 0.01) and Chronic heart failure (OR = 3.15; p < 0.01). Adequate treatment, either monotherapy or combination of antimicrobials, did not modify mortality. There was no difference in 30-day mortality, but 60-day mortality was higher in patients with SM-VAP compared to Other-VAP (P = 0.056). CONCLUSIONS: In a large series, independent risk factors for the SM-VAP were ureido/carboxypenicillin or carbapenem exposure the week before VAP, and respiratory and coagulation components of the SOFA score > 2 before VAP. Mortality risk factors of SM-VAP were age and chronic heart failure. Adequate treatment did not improve SM-VAP prognosis.

"You helped me keep my head above water"-experience of bereavement research after loss of a loved one in the ICU: insights from the ARREVE study.

PURPOSE: Bereavement research has helped to improve end-of-life practices in the ICU. However, few studies have explored bereaved relatives experience of research participation in this context. We aimed to explore the experience of bereaved relatives' participation in the ARREVE study which included three telephone follow-up calls to complete several quantitative tools. METHODS: Volunteer relatives who participated in the 12-month follow-up call completed a questionnaire about research participation that included ten open-ended questions so that respondents could use their own words and thoughts. These open-ended questions were analyzed using qualitative analysis that examines themes within the data. RESULTS: 175/311 relatives completed the questionnaire. Three themes were derived from the thematic analysis: (1) struggling: reactivation of emotional distress associated with the ICU experience and the loss is frequent, specifically during the 1st follow-up call. (2) Resilience: as time goes by, research participation becomes increasingly positive. The calls are a help both in giving meaning to the relatives' experience and in accepting the loss. (3) Recognition: research calls can compensate for the absence of support during bereavement. CONCLUSION: Although some emotional difficulties must be acknowledged, bereavement research is overall associated with benefits, by facilitating emotional adjustments, meaning-making and resilience. Lack of support and social isolation during bereavement are frequent experiences, revealing that support strategies for bereaved relatives should be developed after the loss of a loved one in the ICU.

Optimizing Initial Intrathecal Drug Ratio for Refractory Cancer-Related Pain for Early Pain Relief. A Retrospective Monocentric Study.

OBJECTIVE: Intrathecal (IT) drug delivery has shown its efficiency in treating refractory cancer pain, but switching opioids from the systemic to the intrathecal route is a challenging phase. Moreover, associations are widely used and recommended. Few data deal with the initial dosage of each drug. Analyzing conversion factors and initial dosages used in intrathecal therapy seems essential to decreasing the length of titration and to delivering quick pain relief to patients. METHODS: We retrospectively analyzed data from consecutive adult patients implanted with an intrathecal device for cancer pain and treated at the Institut de Cancérologie de l'Ouest, in Angers, France, for four years. The main goal was to identify factors associated with early pain relief after intrathecal drug delivery system (IDDS) implantation. RESULTS: Of the 220 IDDS-treated patients, 70 (32%) experienced early pain relief (EaPR) and 150 (68%) delayed pain relief (DePR). Performance Status stage and initial IT ropivacaine:IT morphine ratio were the variables independently associated with EaPR. The best IT ropivacaine:IT morphine ratio to predict EaPR was 5:1, with a 73% (95% confidence interval [CI] = 64.8% to 79.6%) sensitivity and a 67.1% (95% CI = 54.9% to 77.9%) specificity. EaPR subjects experienced better pain relief (-84% vs -60% from baseline pain score, P < 0.0001), shorter length of hospitalization (7 vs 10 days, P < 0.0001), and longer survival (155 vs 82 days, P = 0.004). CONCLUSIONS: Local anesthetic:morphine ratio should be considered when starting IDDS treatment. EaPR during the IT analgesia titration phase was associated with better pain relief and outcomes in patients with refractory cancer-related pain.

Neutropenic Enterocolitis in Critically Ill Patients: Spectrum of the Disease and Risk of Invasive Fungal Disease.

OBJECTIVES: Neutropenic enterocolitis occurs in about 5.3% of patients hospitalized for hematologic malignancies receiving chemotherapy. Data from critically ill patients with neutropenic enterocolitis are scarce. Our objectives were to describe the population of patients with neutropenic enterocolitis admitted to an ICU and to investigate the risk factors of invasive fungal disease. DESIGN: A multicentric retrospective cohort study between January 2010 and August 2017. SETTING: Six French ICUs members of the Groupe de Recherche Respiratoire en Onco-Hématologie research network. PATIENTS: Adult neutropenic patients hospitalized in the ICU with a diagnosis of enteritis and/or colitis. Patients with differential diagnosis (Clostridium difficile colitis, viral colitis, inflammatory enterocolitis, mesenteric ischemia, radiation-induced gastrointestinal toxicity, and Graft vs Host Disease) were excluded. INTERVENTIONS: None. MEASUREMENT AND MAIN RESULTS: We included 134 patients (median Sequential Organ Failure Assessment 10 [8-12]), with 38.8% hospital mortality and 32.1% ICU mortality rates. The main underlying malignancies were acute leukemia (n = 65, 48.5%), lymphoma (n = 49, 36.6%), solid tumor (n = 14, 10.4%), and myeloma (n = 4, 3.0%). Patients were neutropenic during a median of 14 days (9-22 d). Infection was documented in 81 patients (60.4%), including an isolated bacterial infection in 64 patients (47.8%), an isolated fungal infection in nine patients (6.7%), and a coinfection with both pathogens in eight patients (5.0%). Radiologically assessed enteritis (odds ratio, 2.60; 95% CI, 1.32-7.56; p = 0.015) and HIV infection (odds ratio, 2.03; 95% CI, 1.21-3.31; p = 0.016) were independently associated with invasive fungal disease. CONCLUSIONS: The rate of invasive fungal disease reaches 20% in patients with neutropenic enterocolitis when enteritis is considered. To avoid treatment delay, antifungal therapy might be systematically discussed in ICU patients admitted for neutropenic enterocolitis with radiologically assessed enteritis.

Cuff Leak Test for the Diagnosis of Post-Extubation Stridor: A Multicenter Evaluation Study.

BACKGROUND:: Cuff leak test was developed to predict the occurrence of post-extubation stridor (PES). This study evaluated the diagnostic performance of this test in unselected critically ill patients. METHODS:: Multicenter prospective study including unselected ventilated patients at the time of their first planned extubation. The diagnostic performance of 4 different cuff leak tests was assessed. RESULTS:: Post-extubation stridor occurred in 34 (9.4%) of 362 included patients. Compared to patients without PES, patients with PES required more frequently reintubation (6 [17.6%] vs 26 [7.9%], P = .041), prolonged duration of ventilation (6 [3-13] vs 5 [2-9] days, P = .029), and longer intensive care unit (ICU) stay (12 [6-17.5] vs 7.5 [4-13] days, P = .018). However, ICU mortality was similar in both groups (1 [2.9%] vs 23 [7.0%], P = .61). The 4 cuff leak tests display poor diagnostic accuracy: sensitivities ranging from 27% to 46%, specificities from 70% to 88%, positive predictive values from 14% to 19%, and negative predictive values from 92% to 93%. CONCLUSION:: Post-extubation stridor occurs in less than 10% of unselected critically ill patients. The several cuff leak tests display limited diagnostic performance for the detection of PES. Given the high rate of false positives, routine cuff leak test may expose to undue prolonged mechanical ventilation.

Questions to improve family-staff communication in the ICU: a randomized controlled trial.

PURPOSE: Relatives of intensive care unit (ICU) patients suffer emotional distress that impairs their ability to acquire the information they need from the staff. We sought to evaluate whether providing relatives with a list of important questions was associated with better comprehension on day 5. METHODS: Randomized, parallel-group trial. Relatives of mechanically ventilated patients were included from 14 hospitals belonging to the FAMIREA study group in France. A validated list of 21 questions was handed to the relatives immediately after randomization. The primary endpoint was comprehension on day 5. Secondary endpoints were satisfaction (Critical Care Family Needs Inventory, CCFNI) and symptoms of anxiety and depression (Hospital Anxiety and Depression Scale, HADS). RESULTS: Of 394 randomized relatives, 302 underwent the day-5 assessment of all outcomes. Day-5 family comprehension was adequate in 68 (44.2%) and 75 (50.7%) intervention and control group relatives (P = 0.30), respectively. Over the first five ICU days, median number of family-staff meetings/patient was 6 [3-9], median total meeting time was 72.5 [35-110] min, and relatives asked a median of 20 [8-33] questions including 11 [6-13] from the list, with no between-group difference. Satisfaction and anxiety/depression symptoms were not significantly different between groups. The only variable significantly associated with better day-5 comprehension by multivariable analysis was a higher total number of questions asked before day 5. CONCLUSIONS: Providing relatives with a list of questions did not improve day-5 comprehension, secondary endpoints, or information time. Further research is needed to help families obtain the information they need. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02410538.

Comparison of etomidate and sodium thiopental for induction during rapid sequence intubation in convulsive status epilepticus: A retrospective single-center study.

PURPOSE: Few outcome data are available about morbidity associated with endotracheal intubation modalities in critically ill patients with convulsive status epilepticus. We compared etomidate versus sodium thiopental for emergency rapid sequence intubation in patients with out-of-hospital convulsive status epilepticus. METHODS: Patients admitted to our intensive care unit in 2006-2015 were studied retrospectively. The main outcome measure was seizure and/or status epilepticus recurrence within 12 h after rapid sequence intubation. RESULTS: We included 97 patients (60% male; median age, 59 years [IQR, 48-70]). Median time from seizure onset to first antiepileptic drug was 60 min [IQR, 35-90]. Reasons for intubation were coma in 95 (98%), acute respiratory distress in 18 (19%), refractory convulsive status epilepticus in 9 (9%), and shock in 6 (6%) patients; 50 (52%) patients had more than one reason. The hypnotic drugs used were etomidate in 54 (56%) and sodium thiopental in 43 (44%) patients. Seizure and/or status epilepticus recurred in 13 (56%) patients in the etomidate group and 11 patients (44%) in the sodium thiopental group (adjusted common odds ratio [aOR], 0.98; 95%CI, 0.36-2.63; P = 0.97). The two groups were not significantly different for proportions of patients with hemodynamic instability after intubation (aOR, 0.60; 95%CI, 0.23-1.58; P = 0.30) or with difficult endotracheal intubation (OR, 1.28; 95% CI 0.23 to 7.21; P=0.77). CONCLUSIONS: Our findings argue against a difference in seizure and/or status epilepticus recurrences rates between critically ill patients with convulsive status epilepticus given etomidate vs. sodium thiopental as the induction agent for emergency intubation.

Usefulness of early plasma S-100B protein and Neuron-Specific Enolase measurements to identify cerebrovascular etiology of out-of-hospital cardiac arrest.

BACKGROUND: While S-100B protein and Neuron-Specific Enolase (NSE) dosages have been extensively investigated for neurological prognostication after cardiac arrest (CA), there is no data about their ability to detect a cerebrovascular cause of CA. We assessed the utility of plasma S-100B protein and NSE measurements for early diagnosis of primary neurological cause in resuscitated CA patients. PATIENTS AND METHODS: Case control study based on two prospectively acquired CA databases. Patients with a primary cerebrovascular etiology were compared with randomly selected CA of non-neurological cause. S-100B protein and NSE were measured at ICU admission in all patients. RESULTS: CA was due to a cerebrovascular etiology in 18 patients (subarachnoid hemorrhage, n = 15; ischemic stroke, n = 3), with an ICU mortality of 100%. Comparative group was constituted with 66 patients (cardiac etiology n = 45, respiratory etiology n = 21), with an ICU mortality of 71%. Admission S-100B protein concentration was 2.0 [0.63-7.15] µg/L in the cerebrovascular group and 0.45 [0.24-1.95] in the non-cerebrovascular group (p < 0.001). In contrast, NSE concentration was similar in cerebrovascular and non-cerebrovascular etiologies (35 [25-103] µg/L vs. 27 [19-47] respectively, p = 0.16). Area under ROC curves for S-100B protein and NSE to predict cerebrovascular cause of CA was 0.75 [95% CI: 0.64-0.87] and 0.61 [95% CI: 0.45-0.76], respectively. CONCLUSIONS: Even if S-100B protein dosage performs slightly better than NSE, early dosages of these biomarkers are poorly predictive of a cerebrovascular etiology of CA. Our results suggest that early measurement of brain biomarkers should not be recommended to tailor the imaging strategy employed to investigate the CA cause.

Terminal weaning or immediate extubation for withdrawing mechanical ventilation in critically ill patients (the ARREVE observational study).

PURPOSE: The relative merits of immediate extubation versus terminal weaning for mechanical ventilation withdrawal are controversial, particularly regarding the experience of patients and relatives. METHODS: This prospective observational multicentre study (ARREVE) was done in 43 French ICUs to compare terminal weaning and immediate extubation, as chosen by the ICU team. Terminal weaning was a gradual decrease in the amount of ventilatory assistance and immediate extubation was extubation without any previous decrease in ventilatory assistance. The primary outcome was posttraumatic stress symptoms (Impact of Event Scale Revised, IES-R) in relatives 3 months after the death. Secondary outcomes were complicated grief, anxiety, and depression symptoms in relatives; comfort of patients during the dying process; and job strain in staff. RESULTS: We enrolled 212 (85.5%) relatives of 248 patients with terminal weaning and 190 relatives (90.5%) of 210 patients with immediate extubation. Immediate extubation was associated with airway obstruction and a higher mean Behavioural Pain Scale score compared to terminal weaning. In relatives, IES-R scores after 3 months were not significantly different between groups (31.9 ± 18.1 versus 30.5 ± 16.2, respectively; adjusted difference, -1.9; 95% confidence interval, -5.9 to 2.1; p = 0.36); neither were there any differences in complicated grief, anxiety, or depression scores. Assistant nurses had lower job strain scores in the immediate extubation group. CONCLUSIONS: Compared to terminal weaning, immediate extubation was not associated with differences in psychological welfare of relatives when each method constituted standard practice in the ICU where it was applied. Patients had more airway obstruction and gasps with immediate extubation. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT01818895.

The Clinical Picture of Severe Systemic Capillary-Leak Syndrome Episodes Requiring ICU Admission.

OBJECTIVE: Systemic capillary-leak syndrome is a very rare cause of recurrent hypovolemic shock. Few data are available on its clinical manifestations, laboratory findings, and outcomes of those patients requiring ICU admission. This study was undertaken to describe the clinical pictures and ICU management of severe systemic capillary-leak syndrome episodes. DESIGN, SETTING, PATIENTS: This multicenter retrospective analysis concerned patients entered in the European Clarkson's disease (EurêClark) Registry and admitted to ICUs between May 1992 and February 2016. MEASUREMENTS AND MAIN RESULTS: Fifty-nine attacks occurring in 37 patients (male-to-female sex ratio, 1.05; mean ± SD age, 51 ± 11.4 yr) were included. Among 34 patients (91.9%) with monoclonal immunoglobulin G gammopathy, 20 (58.8%) had kappa light chains. ICU-admission hemoglobin and proteinemia were respectively median (interquartile range) 20.2 g/dL (17.9-22 g/dL) and 50 g/L (36.5-58.5 g/L). IV immunoglobulins were infused (IV immunoglobulin) during 15 episodes (25.4%). A compartment syndrome developed during 12 episodes (20.3%). Eleven (18.6%) in-ICU deaths occurred. Bivariable analyses (the 37 patients' last episodes) retained Sequential Organ-Failure Assessment score greater than 10 (odds ratio, 12.9 [95% CI, 1.2-140]; p = 0.04) and cumulated fluid-therapy volume greater than 10.7 L (odds ratio, 16.8 [1.6-180]; p = 0.02) as independent predictors of hospital mortality. CONCLUSIONS: We described the largest cohort of severe systemic capillary-leak syndrome flares requiring ICU admission. High-volume fluid therapy was independently associated with poorer outcomes. IV immunoglobulin use was not associated with improved survival; hence, their use should be considered prudently and needs further evaluation in future studies.
