ARF etiologies are numerous, and despite extensive diagnostic workflow, some patients remain with undetermined ARF etiology. Methods: This is a post-hoc study of a prospective multicenter cohort performed on 1011 critically ill hematological patients. Relationship between ARF etiology and hospital mortality was assessed using a multivariable regression model adjusting for confounders. Results: This study included 604 patients with ARF. All patients underwent noninvasive diagnostic tests, and a bronchoscopy and bronchoalveolar lavage (BAL) was performed in 155 (25.6%). Definite diagnoses were classified into four exclusive etiological categories: pneumonia (44.4%), non-infectious diagnoses (32.6%), opportunistic infection (10.1%) and undetermined (12.9%), with corresponding hospital mortality rates of 40, 35, 55 and 59%, respectively. Overall hospital mortality was 42%. By multivariable analysis, factors associated with hospital mortality were invasive pulmonary aspergillosis (OR 7.57 (95% CI 3.06-21.62); p < 0.005), use of invasive mechanical ventilation (OR 1.65 (95% CI 1.07-2.55); p = 0.02), a SOFA score >7 (OR 3.32 (95% CI 2.15-5.15); p < 0.005) and an undetermined ARF etiology (OR 2.92 (95% CI 1.71-5.07); p < 0.005). Conclusions: In patients with hematological malignancies and ARF, up to 13% remain with undetermined ARF etiology despite comprehensive diagnostic workup. Undetermined ARF etiology is independently associated with hospital mortality. Studies to guide second-line diagnostic strategies are warranted.

Specificities in the management of critically ill neutropenic patients prompted the establishment of guidelines dedicated to intensivists. These recommendations were drawn up by a panel of experts brought together by the French Intensive Care Society in collaboration with the French Group for Pediatric Intensive Care Emergencies, the French Society of Anesthesia and Intensive Care, the French Society of Hematology, the French Society for Hospital Hygiene, and the French Infectious Diseases Society. Literature review and formulation of recommendations were performed using the Grading of Recommendations Assessment, Development and Evaluation system. Each recommendation was then evaluated and rated by each expert using a meth...

Few data are available on the performance of serum (1-3)-β-D-glucan (BG) assays for diagnosing IFI in patients with hematological malignancies admitted to the intensive care unit (ICU). In this study, 737 consecutive patients with hematological malignancies admitted to 17 ICUs routinely underwent a BG assay at ICU admission. IFIs were diagnosed using standard criteria applied by three independent specialists. Among the 737 patients, 439 (60%) required mechanical ventilation and 273 (37%) died before hospital discharge. Factors known to alter BG concentrations were identified in most patients. IFIs were documented in 78 (10.6%) patients (invasive pulmonary aspergillosis, n = 54; Pneumocystis jirovecii pneumonia, n = 13; candidemia, n = 13; and fusarium infections, n = 3). BG concentrations (pg/mL) were higher in patients with th...

We sought to appraise the incidence, risk factors, and outcome of AKI in a large multicentre cohort study of critically ill patients with haematological malignancies. We used a retrospective analysis of a prospectively collected database. The study was carried out in 17 university or university-affiliated centres in France and Belgium between 2010 and 2012. AKI was defined according to the Acute Kidney Injury Network (AKIN) definition. Of the 1011 patients admitted into the intensive care unit (ICU) during the study period, 1009 were included in this study. According to the AKIN definition, 671 patients (66.5%) developed an AKI during their ICU stay, of which 258 patients (38.4%) were AKI stage 1, 75 patients (11.2%) AKI stage 2 and 338 patients (50.4%) AKI stage 3. After adjustment for confounders, main adverse risk factors of AKI were older age, severity [non-rena...

Prospective open non comparative study. Twenty-nine class ASA I and II adults undergoing a stomatological procedure of short duration were included in the study. General anaesthesia was obtained with a continuous infusion of propofol, supplemented with alfentanil and N2O-O2 mixture. Neuromuscular blockade, assessed with electromyography of the adductor pollicis muscle, was obtained with mivacurium (150 micrograms.kg-1). After restoration of 5% of neuromuscular transmission, mivacurium was administered by continuous infusion in order to maintain a blockade between 91 and 99%. The delay for decreasing twitch height by 95% was 2.9 +/- 1.0 min. The mean dose for maintenance of blockade was 10.9 +/- 1.5 micrograms.kg-1.min-1. The delay of spontaneous recovery from blockade was 10.2 min, 16.6 min and 21.3 min for obtaining 25, 75 and 95% twitchs respectively. The delay for the twitch increase from 25 to 75% was 6.6 min. Mivacurium in continuous infusion provides rapidly a deep and stable neuromuscular blockade followed by a rapid spontaneous restoration of neuromuscular transmission in patients with normal pseudocholinesterases.

In patients with severe hypoxemia, high-flow nasal oxygen (HFNO) therapy has been used as an alternative to delivery of oxygen via a Venturi mask. Our objective in the present study was to compare HFNO and Venturi mask oxygen in immunocompromised patients with ARF. We conducted a multicenter, parallel-group randomized controlled trial in four intensive care units. Inclusion criteria were hypoxemic ARF and immunosuppression, defined as at least one of the following: solid or hematological malignancy, steroid or other immunosuppressant drug therapy, and HIV infection. Exclusion criteria were hypercapnia, previous IMV, and immediate need for IMV or noninvasive ventilation (NIV). Patients were randomized to 2 h of HFNO or Venturi mask oxygen. The primary endpoint was a need for IMV or NIV during the 2-h oxygen therapy peri...

It is unclear whether these complications impact equally on long-term outcome. Prospective observational study including the patients admitted to the surgical intensive care unit between January 2009 and October 2011 after elective gastroesophageal and pancreatic surgery. Risk factors for 30-day major postoperative events and long-term outcome were evaluated. During the study period, 259 patients were consecutively included. Among them, 166 (64%), 54 (21%), and 39 (15%) patients underwent pancreatic surgery, gastric surgery, and esophageal surgery, respectively. Using the Clavien-Dindo classification, 117 patients (45%) developed at least 1 postoperative complication, including 60 (23%) patients with acute respiratory failure, 77 (30%) with sepsis, and 89 (34%) with surgical complications. The median follow-up from the time of intensive care unit admission was 34 months (95% confidence interval, 30-37 months).The 1-year survival was 95% (95% confidence interval, 92-98). Among the perioperative variables, postoperative sepsis and an American Society of Anesthesiologists score higher than 2 were independently associated with long-term mortality. In septic patients, death (n = 16) was significantly associated with cancer recurrence (n = 10; P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; .0001). Independent factors associated with postoperative sepsis were a Sequential Organ Failure Assessment score on day 1, a systemic inflammatory response syndrome on day 3, positive intraoperative microbiological samples, Simplified Acute Physiology Score II and an American Society of Anesthesiologists score higher than 2 (P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; .005). Postoperative sepsis was the only major postoperative event associated with long-term mortality. Postoperative sepsis may reflect a deep impairment of immune response, which is potentially associated with cancer recurrence and mortality.

However, mortality of intubated patients decreased in the last years. In this study, we assess outcomes in those patients according to the initial ventilation strategy. We performed a post hoc analysis of a prospective multicentre study of critically ill hematology patients, in 17 intensive care units in France and Belgium. Patients with hematological malignancies admitted for ARF in 2010 and 2011 and who were not intubated at admission were included in the study. A propensity score-based approach was used to assess the impact of NIV compared to oxygen only on hospital mortality. Among 1011 patients admitted to ICU during the study period, 380 met inclusion criteria. Underlying diseases included lymphoid (n = 162, 42.6 %) or myeloid (n = 141, 37.1 %) diseases. ARF etiologies were pulmonary infections (n = 161, 43 %), mal...

However, its effectiveness for this indication remains unclear. To determine whether early noninvasive ventilation improved survival in immunocompromised patients with nonhypercapnic acute hypoxemic respiratory failure. Multicenter randomized trial conducted among 374 critically ill immunocompromised patients, of whom 317 (84.7%) were receiving treatment for hematologic malignancies or solid tumors, at 28 intensive care units (ICUs) in France and Belgium between August 12, 2013, and January 2, 2015. Patients were randomly assigned to early noninvasive ventilation (n = 191) or oxygen therapy alone (n = 183). The primary outcome was day-28 mortality. Secondary outcomes were intubation, Sequential Organ Failure Assessment score on day 3, ICU-acquired infections, duration of mechanical ventilation, and ICU length of stay. At randomization, median ...

Overall, when these patients receive reduced intensity conditioning (RIC) regimens, the survival is better. To date, no study has specifically evaluated the outcome of RIC allogeneic HSCT admitted to the ICU. We realized a retrospective study of 102 patients admitted to the ICU among a cohort of 601 consecutive patients receiving RIC regimens. The primary objective of the study was to assess in-ICU and inhospital mortality rates. The ICU mortality was 39.2%, and the hospital mortality was 59.8%. The median overall survival of ICU patients was 8.2 months (95% confidence interval [CI], 5.7-10.6) vs 75 (95% CI, 63-87) in non-ICU patients (P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; .0001). During hospital stay, an ICU admission for neurologic dysfunction was independently associated with hospital survival (P = .012). The use of invasive mechanical ventilation (IMV; P = .011), Simplified Acute Physiology Score II (P = .003), and longer time between diagnosis of malignancy and HSCT (P = .012) were associated with hospital mortality. The overall survival of the ICU survivors was significantly lower than that of non-ICU patients (hazard ratio, 3.61 [95% CI, 2.18-4.59]; P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; .001). The median survival of ICU survivors was 9 months (95% CI, 4-14) vs 75 (95% CI, 63-87) in non-ICU patients (P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; .0001). Noninvasive ventilation (NIV) was successful (not followed by IMV in 61% of cases [25/41 NIV patients]), and failure of NIV was not associated with hospital mortality in patients treated with subsequent IMV. From our study, short-term survival rates of ICU patients receiving RIC regimens justify a broad ICU admission policy. The use of IMV is associated with hospital mortality, whereas the use of NIV is frequently successful. Long-term outcome remains poor after ICU discharge.

This is the result of intensive and effective treatments that also increase the probability of infiltrative, infectious or toxic life threatening event. Over the last two decades, the number of patients with HMs admitted to the ICU increased and their mortality has dropped sharply. ICU patients with HMs require an extensive diagnostic workup and the optimal use of ICU treatments to identify the reason for ICU admission and the nature of the complication that explains organ dysfunctions. Mortality of ARDS or septic shock is up to 50%, respectively. In this review, the authors share their experience with managing critically ill patients with HMs. They discuss the main aspects of the diagnostic and therapeutic management of critically ill patients with HMs and argue that outcomes have improved over time and that many classic determinants of mortality have become irrelevant.

Patients are frequently admitted to Intensive Care Unit (ICU) for severe sepsis or septic shock. Empirical antibiotic treatment, including monotherapy β-lactam covering Pseudomonas aeruginosa, must be prompt. The ICU management is slightly different, due to a particular microbial ecology. A standardized approach to obtain a microbiological documentation is the cornerstone in these patients, leading to an adapted antimicrobial treatment. Systematic reassessment of initial antibiotic regimen should be realised. Neutropenic patients with severe sepsis or septic shock should receive promptly a β-lactam-aminoglycoside combination, as well as glycopeptides in case of severity or absence of documented infection. Early catheter removal should be considered widely. In the actual context of growing resistance, antibiotics saving became a major concern. According to context and microbial documentation, an escalade or d...

The main objective of this study was to describe outcomes and to identify early predictors of hospital mortality in critically ill cancer patients with ARF during chemotherapy-induced neutropenia. Retrospective analysis of prospectively collected data extracted from two recent prospective multicentre studies. We included neutropenic adults admitted to the ICU for ARF. Of the 123 study patients, 107 patients (87%) had haematological malignancies; 78 (64%) were male, median age was 57 years (44-62), and median LOD score at ICU admission was 6 (4-9). ICU and hospital mortality rates were 42% and 77%, respectively. Endotracheal mechanical ventilation was an independent risk factor for hospital mortality (odds ratio [OR], 7.73; 95% confidence interval [95%CI], 2.52-23.69); two factors independently protected from hospital mortality, namely, ICU admission for AR...

We analyzed data from a previous randomized controlled trial in which nonintubated oncology and hematology subjects with ARF were randomized to early bronchoalveolar lavage or routine care in 16 ICUs in France. Consecutive patients with malignancies were admitted to the ICU for ARF in 2005 and 2006 with no intervention. During the study period, 219 patients were admitted to the ICU for ARF, and 8 patients were not included due to a nonintubation order. Data on the underlying disease, pulmonary involvement, and extrapulmonary organ dysfunctions were recorded at admission in the 211 remaining subjects. Ventilatory support included oxygen only (49 subjects), noninvasive ventilation (NIV) only (81 subjects), NIV followed by invasive mechanical ventilation (49 subjects), and first-line invasive mechanical ventilation (32 subjects). The 81 subjects who required ...

However, its effectiveness for this indication remains unclear. To determine whether early noninvasive ventilation improved survival in immunocompromised patients with nonhypercapnic acute hypoxemic respiratory failure. Multicenter randomized trial conducted among 374 critically ill immunocompromised patients, of whom 317 (84.7%) were receiving treatment for hematologic malignancies or solid tumors, at 28 intensive care units (ICUs) in France and Belgium between August 12, 2013, and January 2, 2015. Patients were randomly assigned to early noninvasive ventilation (n = 191) or oxygen therapy alone (n = 183). The primary outcome was day-28 mortality. Secondary outcomes were intubation, Sequential Organ Failure Assessment score on day 3, ICU-acquired infections, duration of mechanical ventilation, and ICU length of stay. At randomization, median ...

Overall, when these patients receive reduced intensity conditioning (RIC) regimens, the survival is better. To date, no study has specifically evaluated the outcome of RIC allogeneic HSCT admitted to the ICU. We realized a retrospective study of 102 patients admitted to the ICU among a cohort of 601 consecutive patients receiving RIC regimens. The primary objective of the study was to assess in-ICU and inhospital mortality rates. The ICU mortality was 39.2%, and the hospital mortality was 59.8%. The median overall survival of ICU patients was 8.2 months (95% confidence interval [CI], 5.7-10.6) vs 75 (95% CI, 63-87) in non-ICU patients (P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; .0001). During hospital stay, an ICU admission for neurologic dysfunction was independently associated with hospital survival (P = .012). The use of invasive mechanical ventilation (IMV; P = .011), Simplified Acute Physiology Score II (P = .003), and longer time between diagnosis of malignancy and HSCT (P = .012) were associated with hospital mortality. The overall survival of the ICU survivors was significantly lower than that of non-ICU patients (hazard ratio, 3.61 [95% CI, 2.18-4.59]; P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; .001). The median survival of ICU survivors was 9 months (95% CI, 4-14) vs 75 (95% CI, 63-87) in non-ICU patients (P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; .0001). Noninvasive ventilation (NIV) was successful (not followed by IMV in 61% of cases [25/41 NIV patients]), and failure of NIV was not associated with hospital mortality in patients treated with subsequent IMV. From our study, short-term survival rates of ICU patients receiving RIC regimens justify a broad ICU admission policy. The use of IMV is associated with hospital mortality, whereas the use of NIV is frequently successful. Long-term outcome remains poor after ICU discharge.

This is the result of intensive and effective treatments that also increase the probability of infiltrative, infectious or toxic life threatening event. Over the last two decades, the number of patients with HMs admitted to the ICU increased and their mortality has dropped sharply. ICU patients with HMs require an extensive diagnostic workup and the optimal use of ICU treatments to identify the reason for ICU admission and the nature of the complication that explains organ dysfunctions. Mortality of ARDS or septic shock is up to 50%, respectively. In this review, the authors share their experience with managing critically ill patients with HMs. They discuss the main aspects of the diagnostic and therapeutic management of critically ill patients with HMs and argue that outcomes have improved over time and that many classic determinants of mortality have become irrelevant.

Patients are frequently admitted to Intensive Care Unit (ICU) for severe sepsis or septic shock. Empirical antibiotic treatment, including monotherapy β-lactam covering Pseudomonas aeruginosa, must be prompt. The ICU management is slightly different, due to a particular microbial ecology. A standardized approach to obtain a microbiological documentation is the cornerstone in these patients, leading to an adapted antimicrobial treatment. Systematic reassessment of initial antibiotic regimen should be realised. Neutropenic patients with severe sepsis or septic shock should receive promptly a β-lactam-aminoglycoside combination, as well as glycopeptides in case of severity or absence of documented infection. Early catheter removal should be considered widely. In the actual context of growing resistance, antibiotics saving became a major concern. According to context and microbial documentation, an escalade or d...

The main objective of this study was to describe outcomes and to identify early predictors of hospital mortality in critically ill cancer patients with ARF during chemotherapy-induced neutropenia. Retrospective analysis of prospectively collected data extracted from two recent prospective multicentre studies. We included neutropenic adults admitted to the ICU for ARF. Of the 123 study patients, 107 patients (87%) had haematological malignancies; 78 (64%) were male, median age was 57 years (44-62), and median LOD score at ICU admission was 6 (4-9). ICU and hospital mortality rates were 42% and 77%, respectively. Endotracheal mechanical ventilation was an independent risk factor for hospital mortality (odds ratio [OR], 7.73; 95% confidence interval [95%CI], 2.52-23.69); two factors independently protected from hospital mortality, namely, ICU admission for AR...

We analyzed data from a previous randomized controlled trial in which nonintubated oncology and hematology subjects with ARF were randomized to early bronchoalveolar lavage or routine care in 16 ICUs in France. Consecutive patients with malignancies were admitted to the ICU for ARF in 2005 and 2006 with no intervention. During the study period, 219 patients were admitted to the ICU for ARF, and 8 patients were not included due to a nonintubation order. Data on the underlying disease, pulmonary involvement, and extrapulmonary organ dysfunctions were recorded at admission in the 211 remaining subjects. Ventilatory support included oxygen only (49 subjects), noninvasive ventilation (NIV) only (81 subjects), NIV followed by invasive mechanical ventilation (49 subjects), and first-line invasive mechanical ventilation (32 subjects). The 81 subjects who required ...

In this situation, the mortality rate is very high despite amphotericin B therapy. We report a case of disseminated T. asahii infection in a 17-year-old neutropenic patient with acute leukemia, septic shock, and acute respiratory distress syndrome (ARDS)
