Extracorporeal membrane oxygenation in trauma patient in France: a retrospective nationwide registry.

Background: Indications for Veno-venous (VV) or veno-arterial (VA) extracorporeal membrane oxygenation (ECMO) after trauma rely on poor evidence. The main aims were to describe the population of trauma patients requiring either VV or VA ECMO and report their clinical management and outcomes.

Methods: An observational multicentre retrospective study was conducted in 17 Level 1 trauma centres in France between January 2010 and December 2021.

Should we perform decompressive laparotomy during severe acute pancreatitis with intra-abdominal hypertension below 25 mmHg: Only the gut knows.

We suggest that during severe acute pancreatitis (SAP) with intra-abdominal hypertension, practitioners should consider decompressive laparotomy, even with intra-abdominal pressure (IAP) below 25 mmHg. Indeed, in this setting, non-occlusive mesenteric ischemia (NOMI) may occur even with IAP below this cutoff and lead to transmural necrosis if abdominal perfusion pressure is not promptly restored. We report our experience of 18 critically ill patients with SAP having undergone decompressive laparotomy of which one third had NOMI while IAP was mostly below 25 mmHg.

Oxygenation management during veno-arterial ECMO support for cardiogenic shock: a multicentric retrospective cohort study.

Backgound: Hyperoxemia is common and associated with poor outcome during veno-arterial extracorporeal membrane oxygenation (VA ECMO) support for cardiogenic shock. However, little is known about practical daily management of oxygenation. Then, we aim to describe sweep gas oxygen fraction (FO), postoxygenator oxygen partial pressure (PO), inspired oxygen fraction (FO), and right radial arterial oxygen partial pressure (PO) between day 1 and day 7 of peripheral VA ECMO support.

Prone Positioning During Extracorporeal Membrane Oxygenation in Patients With Severe ARDS: The PRONECMO Randomized Clinical Trial.

Importance: Prone positioning may improve outcomes in patients with severe acute respiratory distress syndrome (ARDS), but it is unknown whether prone positioning improves clinical outcomes among patients with ARDS who are undergoing venovenous extracorporeal membrane oxygenation (VV-ECMO) compared with supine positioning.

Objective: To test whether prone positioning vs supine positioning decreases the time to successful ECMO weaning in patients with severe ARDS supported by VV-ECMO.

Design, Setting, And Participants: Randomized clinical trial of patients with severe ARDS undergoing VV-ECMO for less than 48 hours at 14 intensive care units (ICUs) in France between March 3, 2021, and December 7, 2021.

Plasma citrulline concentration and plasma LPS detection among critically ill patients a prospective observational study.

Purpose: Gut can be a source of sepsis but sepsis itself can induce gut dysfunction. We aimed to study whether plasma citrulline, a marker of enterocyte mass, was correlated with plasma lipopolysaccharide, a potential marker of bacterial translocation among critically ill patients.

Materials And Methods: Critically ill patients admitted to the ICU.

Coma With Hyperammonemia in a Patient With Kwashiorkor.

We describe a case of coma-related hyperammonemia in a woman presenting with severe edematous malnutrition (Kwashiorkor-like), without underlying hepatic disease. Our main hypothesis is that the patient developed a functional urea cycle disorder, due to the inability to synthesize N-acetylglutamate which is the activator of the first enzymes (carbamoyl phosphate synthetase) of urea cycle, in a context of severe deficiency of essential amino acids and of acetyl-CoA. Severe hyperammonemia is a medical emergency exposing to the risk of cerebral edema.

Comparative outcomes of extracorporeal membrane oxygenation for COVID-19 delivered in experienced European centres during successive SARS-CoV-2 variant outbreaks (ECMO-SURGES): an international, multicentre, retrospective cohort study.

Background: To inform future research and practice, we aimed to investigate the outcomes of patients who received extracorporeal membrane oxygenation (ECMO) for acute respiratory distress syndrome (ARDS) due to different variants of SARS-CoV-2.

Methods: This retrospective study included consecutive adult patients with laboratory-confirmed SARS-CoV-2 infection who received ECMO for ARDS in 21 experienced ECMO centres in eight European countries (Austria, Belgium, England, France, Germany, Italy, Portugal, and Spain) between Jan 1, 2020, and Sept 30, 2021. We collected data on patient characteristics, clinical status, and management before and after the initiation of ECMO.

Abdominal atherosclerosis is not a risk factor of nonocclusive mesenteric ischemia among critically ill patients: a propensity matching study.

Background: Although risk factors of occlusive acute mesenteric ischemia are well known, triggering factors of nonocclusive mesenteric ischemia (NOMI) remain unclear. Alongside to the known risk factors for NOMI, the role of atherosclerosis is not fully elucidated. The purpose of our study was to evaluate whether abdominal atherosclerosis is a risk factor for NOMI.

One-Year Mental and Physical Health Assessment in Survivors after Extracorporeal Membrane Oxygenation for COVID-19-related Acute Respiratory Distress Syndrome.

Long-term outcomes of patients with coronavirus disease (COVID-19)-related acute respiratory distress syndrome treated with extracorporeal membrane oxygenation (ECMO) are unknown. To assess physical examination, pulmonary function tests, anxiety, depression, post-traumatic stress disorder and quality of life at 6 and 12 months after ECMO onset. Multicenter, prospective study in patients who received ECMO for COVID-19 acute respiratory distress syndrome from March to June 2020 and survived hospital discharge.

Management and outcomes of pregnant women admitted to intensive care unit for severe pneumonia related to SARS-CoV-2 infection: the multicenter and international COVIDPREG study.

Purpose: Management and outcomes of pregnant women with coronavirus disease 2019 (COVID-19) admitted to intensive care unit (ICU) remain to be investigated.

Methods: A retrospective multicenter study conducted in 32 ICUs in France, Belgium and Switzerland. Maternal management as well as maternal and neonatal outcomes were reported.

Optimizing PO during peripheral veno-arterial ECMO: a narrative review.

During refractory cardiogenic shock and cardiac arrest, veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is used to restore a circulatory output. However, it also impacts significantly arterial oxygenation. Recent guidelines of the Extracorporeal Life Support Organization (ELSO) recommend targeting postoxygenator partial pressure of oxygen (PO) around 150 mmHg.

Prognostic Factors in Non-occlusive mesenteric ischemia: A pragmatic pre-operative score for the prediction of 28-day mortality.

Background: The prognosis of critical ill patients with non-occlusive mesenteric ischemia (NOMI) is poor and not fully understood. We aimed to determine preoperative factors associated with 28-day mortality in NOMI.

Methods: Variables associated with 28-day mortality were entered into a multivariate cox regression model and were used to compute a NOMI mortality score.

Result of one-year, prospective follow-up of intensive care unit survivors after SARS-CoV-2 pneumonia.

Introduction: Survivors of viral ARDS are at risk of long-term physical, functional and neuropsychological complications resulting from the lung injury itself, but also from potential multiorgan dysfunction, and the long stay in the intensive care unit (ICU). Recovery profiles after severe SARS-CoV-2 pneumonia in intensive care unit survivors have yet to be clearly defined.

Material And Methods: The goal of this single-center, prospective, observational study was to systematically evaluate pulmonary and extrapulmonary function at 12 months after a stay in the ICU, in a prospectively identified cohort of patients who survived SARS-CoV-2 pneumonia.

β-lactam dosing at the early phase of sepsis: Performance of a pragmatic protocol for target concentration achievement in a prospective cohort study.

Purpose: We hypothesized that a protocol of standardized fixed dose using prolonged infusion during the early phase of sepsis may avoid insufficient β-lactam concentrations.

Methods: In this single center prospective study, patients with sepsis and vasopressors were enrolled if they were treated by either piperacillin-tazobactam, meropenem or cefepime. Βeta-lactams were administered at fixed dose by prolonged infusion.

Evaluating the Risk of Irreversible Intestinal Necrosis Among Critically Ill Patients With Nonocclusive Mesenteric Ischemia.

Introduction: To identify factors associated with irreversible transmural necrosis (ITN) among critically ill patients experiencing nonocclusive mesenteric ischemia (NOMI) and to compare the predictive value regarding ITN risk stratification with that of the previously described Clichy score.

Methods: All consecutive patients admitted to the intensive care unit between 2009 and 2019 who underwent exploratory laparotomy for NOMI and who had an available contrast-enhanced computed tomography with at least 1 portal venous phase were evaluated for inclusion. Clinical, laboratory, and radiological variables were collected.

Extracorporeal Membrane Oxygenation Cannula-Related Infections: Epidemiology and Risk Factors.

Although being a potential major source of infection in extracorporeal membrane oxygenation (ECMO) patients, data regarding cannula-related infections (CRI) remain scarce. We therefore aimed at describing the epidemiology of CRI among critically ill patients supported by ECMO. Between October 2017 and November 2019, adult patients supported by either venoarterial (VA), venopulmonary arterial, or venovenous (VV) ECMO for more than 24 hours were prospectively enrolled.

New clinical algorithm including fungal biomarkers to better diagnose probable invasive pulmonary aspergillosis in ICU.

Background: The classification of invasive pulmonary aspergillosis (IPA) issued by the European Organization for the Research and Treatment of Cancer/Mycoses Study Group Education and Research Consortium (EORTC/MSGERC) is used for immunocompromised patients. An alternative algorithm adapted to the intensive care unit (ICU) population has been proposed (AspICU), but this algorithm did not include microbial biomarkers such as the galactomannan antigen and the Aspergillus quantitative PCR. The objective of the present pilot study was to evaluate a new algorithm that includes fungal biomarkers (BM-AspICU) for the diagnosis of probable IPA in an ICU population.

Diagnostic performance of CT for the detection of transmural bowel necrosis in non-occlusive mesenteric ischemia.

Objectives: To evaluate the diagnostic performance of CT for transmural necrosis (TN) in non-occlusive mesenteric ischemia (NOMI) according to the bowel segment involved.

Methods: From January 2009 to December 2019, all patients admitted to the intensive care unit (ICU) and requiring laparotomy for NOMI were retrospectively studied. CT had to have been performed within 24 h prior to laparotomy and were reviewed by two abdominal radiologists, with a consensus reading in case of disagreement.

Semi-elemental versus polymeric formula for enteral nutrition in brain-injured critically ill patients: a randomized trial.

Background: The properties of semi-elemental enteral nutrition might theoretically improve gastrointestinal tolerance in brain-injured patients, known to suffer gastroparesis. The purpose of this study was to compare the efficacy and tolerance of a semi-elemental versus a polymeric formula for enteral nutrition (EN) in brain-injured critically ill patients.

Methods: Prospective, randomized study including brain-injured adult patients [Glasgow Coma Scale (GCS) ≤ 8] with an expected duration of mechanical ventilation > 48 h.

Atherosclerosis is associated with poorer outcome in non-occlusive mesenteric ischemia.

Purpose: To evaluate whether abdominal atherosclerosis was associated with poorer outcome in a single-centre cohort of patients suffering from nonocclusive mesenteric ischemia (NOMI).

Methods: From January 2009 to December 2019, 121 consecutive patients from the critical care unit who underwent laparotomy for suspected NOMI and with available unenhanced and contrast-enhanced CT were included. Clinical and biological data at the time of the CT scan were retrospectively extracted from medical charts and reviewed by a single radiologist.
