To characterize etiology, clinical course and outcomes of patients in prolonged refractory status epilepticus (PRSE) and looking for prognostic factors.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.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).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.

Early recognition and an attempt at obtaining microbiological documentation are recommended in patients with non-community-acquired pneumonia (NCAP), whether hospital-acquired (HAP) or health care-associated (HCAP). We aimed to characterize the clinical features and microbial etiologies of NCAP to assess the impact of microbiological investigation on their management.This was a prospective 1-y study in a university hospital with 141 non-mechanically ventilated subjects suspected of having HAP (n = 110) or HCAP (n = 31).Clinical criteria alone poorly identified pneumonia (misdiagnosis in 50% of cases). Microbiological confirmation was achievable in 80 subjects (57%). Among 79 microorganisms isolated, 28 were multidrug-resistant aerobic Gram-negative bacilli and group III Enterobacteriaceae and 6 were methicillin-resistant Staphylococcus aureus. Multidrug-resistant aerobic Gram-negative bacilli accounted for one third of the microorganisms in early-onset HAP and for 50% in late-onset HAP. Methicillin-resistant S. aureus was most often recovered from subjects with HCAP. Inappropriate empirical antibiotics were administered to 36% of subjects with confirmed pneumonia. Forty subjects were admitted to the ICU, 13 (33%) of whom died. Overall, 39 subjects (28%) died in the hospital.Integrating the microbiological investigation in the complex clinical diagnostic workup of patients suspected of having NCAP is mandatory. Respiratory tract specimens should be obtained whenever possible for appropriate management.

OBJECTIVE: Very few data are available for critically ill patients with central or extrapontine myelinolysis and according to available evidence, the prognosis seems to be poor. We aimed to describe the baseline characteristics, the management, the long-term prognosis, and the prognostic factors in central or extrapontine myelinolysis. DESIGN: Retrospective observational study considering modified Rankin Scale score >3 or death as an unfavorable outcome. SETTING: Forty-six French intensive care units. PATIENTS: Thirty-six patients with central or extrapontine myelinolysis treated in 2000-2010. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: At baseline, 31 (86%) patients were alcoholics and 33 (92%) presented with hyponatremia. Mechanical ventilation was required in 32 (89%) patients. At 1-yr follow-up, 11 (31%) patients have died, whereas 14 (56%) survivors have returned to a Rankin score ≤1. Life-supporting therapies were withheld in 11 (31%) patients. Severe cerebral motor disability was the most frequently cited reason. However, five of them were still alive at 1 yr with Rankin score ≤1 for four of them. We found no statistical difference between the 18 (50%) patients with a favorable outcome and the 18 (50%) patients with an unfavorable outcome with regard to severity of illness, suggesting that recovery is possible and unpredictable on the basis of clinical presentation. Chronic alcoholism was less frequent in patients with a favorable outcome as compared with patient with an unfavorable outcome (13 [72%] vs. 18 [100%], p = .04). CONCLUSIONS: The prognosis of critically ill patients with central or extrapontine myelinolysis is better than thus far thought despite initial severe clinical manifestations. Regarding the high rate of decisions to withhold life-supporting therapies, the probability of a favorable outcome might be underestimated by intensivists.

French law allows organ donation after death due to cardiocirculatory arrest. In the Maastricht classification, type III non-heart-beating donors are those who experience cardiocirculatory arrest after the withdrawal of life-sustaining treatments. French authorities in charge of regulating organ donation (Agence de la Biomédecine, ABM) are considering organ collection from Maastricht type III donors. We describe a scenario for Maastricht type III organ donation that fully complies with the ethical norms governing care to dying patients. That organ donation may occur after death should have no impact on the care given to the patient and family. The dead-donor rule must be followed scrupulously: the organ retrieval procedure must neither cause nor hasten death. The decision to withdraw life-sustaining treatments, withdrawal modalities, and care provided to the patient and family must adhere strictly to the requirements set forth in patient-rights legislation (the 2005 Léonetti law in France) and should not be influenced in any way by the possibility of organ donation. A major ethical issue regarding the family is how best to transition from discussing treatmentwithdrawal decisions to discussing possible organ retrieval for donation should the patient die rapidly after treatment withdrawal. Close cooperation between the healthcare team and the organ retrieval team is crucial to minimize the distress of family members during this transition. Modalities for implementing Maastricht type III organ donation are discussed here, including the best location for withdrawing life-sustaining treatments (operating room or intensive care unit). © 2012 Graftieaux et al.

Thrombocytopenia is a very frequent disorder in the intensive care unit. Many etiologies should be searched, and therapeutic approaches differ according to these different causes. However, no guideline exists regarding optimum practices for these situations in critically ill patients. We present recommendations for the management of thrombocytopenia in intensive care unit, excluding pregnancy, developed by an expert group of the French-Language Society of Intensive Care (Société de Réanimation de Langue Française (SRLF), the French Language Group of Paediatric Intensive Care and Emergencies (GFRUP) and of the Haemostasis and Thrombosis Study Group (GEHT) of the French Society of Haematology (SFH). The recommendations cover six fields of application: definition, epidemiology, and prognosis; diagnostic approach; therapeutic aspects; thrombocytopenia and sepsis; iatrogenic thrombocytopenia, with a special focus on heparin-induced thrombocytopenia; and thrombotic microangiopathy. © 2012 Van der Linden et al.; licensee Springer.

Objective: The prognosis of patients with idiopathic pulmonary fibrosis or fibrosing idiopathic nonspecific interstitial pneumonia undergoing invasive mechanical ventilation (MV) for acute respiratory failure is known to be poor. The issue of life support in these patients needs to be reconsidered in light of changes during the past decade in ventilator settings and in the management of acute exacerbation. We therefore aimed to reassess the prognosis of such patients. Methods: We retrospectively assessed the outcomes of all medical patients with idiopathic pulmonary fibrosis or fibrosing idiopathic nonspecific interstitial pneumonia who required invasive MV in 3 university hospitals in the Paris area from January 2002 to April 2009. Results: In total, 27 patients (mean age, 66 ± 12.8 years) required invasive MV in the intensive care unit: 8 (30%) were successfully weaned from MV, and 6 and 4 were discharged from the intensive care unit and the hospital, respectively. Survivals for patients who did not undergo lung transplant were 22%, 3.7%, and 3.7%, at 30 days, 6 months, and 12 months, respectively. Conclusions: We confirm that use of invasive MV for acute respiratory failure in patients with idiopathic pulmonary fibrosis or fibrosing idiopathic nonspecific interstitial pneumonia is associated with a high mortality; however, a subset of patients may be discharged alive from the intensive care unit and hospital, providing an opportunity to consider lung transplant in case of eligibility. Our results suggest that invasive MV should not be systematically denied to these patients but discussed on a case-by-case basis. Copyright © 2014 by The American Association for Thoracic Surgery.

Background: Chronic obstructive pulmonary disease (COPD) patients may develop metabolic alkalosis during weaning from mechanical ventilation. Acetazolamide is one of the treatments used to reverse metabolic alkalosis. Methods: 619 time-respiratory (minute ventilation, tidal volume and respiratory rate) and 207 time-PaCO2 observations were obtained from 68 invasively ventilated COPD patients. We modeled respiratory responses to acetazolamide in mechanically ventilated COPD patients and then simulated the effect of increased amounts of the drug. Results: The effect of acetazolamide on minute ventilation and PaCO2 levels was analyzed using a nonlinear mixed effect model. The effect of different ventilatory modes was assessed on the model. Only slightly increased minute ventilation without decreased PaCO2 levels were observed in response to 250 to 500 mg of acetazolamide administered twice daily. Simulations indicated that higher acetazolamide dosage (>1000 mg daily) was required to significantly increase minute ventilation (P<.001 vs pre-acetazolamide administration). Based on our model, 1000 mg per day of acetazolamide would increase minute ventilation by >0.75 L min-1 in 60% of the population. The model also predicts that 45% of patients would have a decrease of PaCO2>5 mmHg with doses of 1000 mg per day. Conclusions: Simulations suggest that COPD patients might benefit from the respiratory stimulant effect after the administration of higher doses of acetazolamide. © 2014 Heming et al.

Acute respiratory failure (ARF) is the leading reason for intensive care unit (ICU) admission in patients with cancer. The aim of this study was to identify early predictors of death in patients with cancer admitted to the ICU for ARF who were not intubated at admission. We conducted analysis of a prospective randomized controlled trial including 219 patients with cancer with ARF in which day-28 mortality was a secondary endpoint. Mortality at day 28 was 31.1%. By multivariate analysis, independent predictors of day-28 mortality were: age (odds ratio [OR] 1.30/10 years, 95% confidence interval [CI] [1.01-1.68], p = 0.04), more than one line of chemotherapy (OR 2.14, 95% CI [1.08-4.21], p = 0.03), time between respiratory symptoms onset and ICU admission > 2 days (OR 2.50, 95% CI [1.25-5.02], p = 0.01), oxygen flow at admission (OR 1.07/L, 95% CI [1.00-1.14], p = 0.04) and extra-respiratory symptoms (OR 2.84, 95%CI [1.30-6.21], p = 0.01). After adjustment for the logistic organ dysfunction (LOD) score at admission, only time between respiratory symptoms onset and ICU admission > 2 days and LOD score were independently associated with day-28 mortality. Determinants of death include both factors non-amenable to change, and delay in ARF management. These results suggest that early intensive care management of patients with cancer with ARF may translate to better survival. © 2013 Informa UK, Ltd.

To evaluate the diagnostic performances of two training programs for residents with no prior ultrasound experience to reach competences in extended basic critical care transthoracic echocardiography (CCE) including Doppler capabilities.This is a prospective observational study in two intensive care units of teaching hospitals. Group I (five residents) completed a short training program (4-h theory; 3-h practical); group II (six residents) completed a longer training program (6-h theory; 12-h practical). The residents and an expert examined all patients who required a transthoracic echocardiography. Their agreement studied by Cohens coefficient, concordance coefficient correlation (CCC) and Bland-Altman plots was used as an indicator of program effectiveness.Group I performed 136 CCEs (mean/resident 27; range 22-32; 65 in ventilated patients) in 115 patients (62 men; 6418years; Simplified Acute Physiologic Score [SAPS] II 3718). Group II performed 158 CCEs (mean/resident 26; range 21-31; 65 in ventilated patients) in 108 patients (64men; 5817 years; SAPS II 4222). Both groups adequately assessed left ventricular (LV) systolic function ( 0.75, 95% confidence interval [CI] 0.64-0.86; 0.77, 95% CI 0.66-0.88, respectively) and pericardial effusion ( 0.83, 95% CI 0.67-0.99; 0.76, 95% CI 0.60-0.93, respectively). Group II appraised severe right ventricular dilatation and significant left-sided valve disease with good to very good agreement ( 0.80, 95% CI 0.56-0.96; 0.79, 95% CI 0.66-0.93, respectively). Regarding left ventricular ejection fraction, E/A ratio, E/e ratio and aortic peak velocity assessed by group II, CCCs were all >0.70 and the bias (mean difference) SD on Bland-Altman analysis was 1.38.8%, 00.3, 0.42.2 and 0.10.4m/s, respectively. Detection of paradoxical septum ( 0.65, 95% CI 0.37-0.93), of heterogeneous LV contraction ( 0.49, 95% CI 0.33-0.65) and of respiratory variation of the inferior vena cava ( 0.27, 95% CI 0.09-0.45), as well as stroke volume measurement (CCC 0.65, 95% CI 0.54-0.74; biasSD -1.44.7cm), was appraised by group II with moderate agreement requiring probably more comprehensive training.Although a training program blending 6-h theory and 12-h practical may be adapted to achieve some essential competences, it seems to be insufficiently to perform a complete extended basic critical care transthoracic echocardiography including Doppler capabilities.

High frequency oscillatory ventilation (HFOV) has been the subject of extensive physiological research for 30 years and even more so of an intense debate on its potential usefulness in the treatment of acute respiratory distress syndrome (ARDS). This technique has been enthusiastically promoted by some teams until two high-quality randomized clinical trials in adults with ARDS showed that HFOV did not decrease and might have even increased mortality. As a consequence of these results, physiological concepts such as atelectrauma and biotrauma on which ARDS management with HFOV were based should be reexamined. In contrast, the concept of volutrauma, i.e., end-inspiratory overdistension, as the cause for ventilator-induced lung injury might help explain excess mortality during mechanical ventilation of ARDS when inspiratory volumes are too high. This is what might have happened during one of the recent studies on HFOV. Failure of this complex technique must be put in perspective with the dramatic improvement of ARDS prognosis with very simple interventions such as tidal volume reduction, early pharmacological paralysis, and prone positioning which all limited end-inspiratory volume.
