Background: Delayed initiation of venovenous extracorporeal membrane oxygenation (VV-ECMO) may increase the risk of intracranial hemorrhage (ICH) in coronavirus patients. This study aimed to investigate the relationship between ECMO timing and the occurrence of ICH in this critically ill population, providing insights for future epidemic management.

Methods: This retrospective study included coronavirus patients treated with VV-ECMO from March to June 2020.

Introduction: New-onset supraventricular arrhythmia (NOSVA) is the most common arrhythmia in patients with septic shock and is associated with haemodynamic alterations and increased mortality rates. With no data available from randomised trials, clinical practice for patient management varies widely. In this setting, rate control or rhythm control could be beneficial in limiting the duration of shock and preventing evolution to multiorgan dysfunction.

Purpose: Hypoxemia is a risk factor for mortality and long-term neuropsychological impairment during severe acute respiratory distress syndrome (ARDS). Veno-venous extracorporeal membrane oxygenation (VV-ECMO) is a potential treatment for such cases but may not suffice. We aimed to evaluate the effects of pharmacological interventions for cardiac output (CO) control using ivabradine or beta-blockers for refractory hypoxemia during VV-ECMO.

Article Synopsis
  • The study investigated how patients with acute respiratory distress syndrome (ARDS) tolerate changes to the ECMO membrane during veno-venous ECMO (VV-ECMO).
  • Out of 70 patients treated with VV-ECMO, 32 required 56 membrane changes due to complications, with 59% of these changes resulting in severe adverse events such as hypoxemia or cardiac issues.
  • Key factors linked to poor tolerance of membrane changes were identified as low tidal volume, low respiratory compliance, low oxygen levels, and high blood flow through the ECMO system, with specific threshold values established for assessing risk.

Introduction: Prognostication of outcome in severe stroke patients necessitating invasive mechanical ventilation poses significant challenges. The objective of this study was to assess the prognostic significance and prevalence of early electroencephalogram (EEG) abnormalities in adult stroke patients receiving mechanical ventilation.

Methods: This study is a pre-planned ancillary investigation within the prospective multicenter SPICE cohort study (2017-2019), conducted in 33 intensive care units (ICUs) in the Paris area, France.

Introduction: Pulmonary vascular dysfunction during severe acute respiratory distress syndrome (ARDS) may lead to right ventricle (RV) dysfunction and acute cor pulmonale (ACP). The occurrence/persistence of ACP despite conventional extracorporeal membrane oxygenation (ECMO) is a challenging situation. We explored the usefulness of a specific dual-lumen cannula that bypasses the RV, and on which a veno-pulmonary arterial assist (V-P ECMO) was mounted, in ARDS patients.

Background: Left atrial strain (LAS) is a measure of atrial wall deformation during cardiac cycle and reflects atrial contribution to cardiovascular performance. Pathophysiological significance of LAS in critically ill patients with hemodynamic instability has never been explored. This study aimed at describing LAS and its variation during volume expansion and to assess the relationship between LAS components and fluid responsiveness.

Background: Hypercapnia worsens lung vascular dysfunction during acute respiratory distress syndrome (ARDS). We tested whether an extracorporeal carbon dioxide removal (ECCOR) device based on a renal replacement therapy platform (Prismalung®) may reduce PaCO and alleviate lung vascular dysfunction in ARDS patients with refractory hypercapnia.

Methods: We planned to prospectively include 20 patients with moderate-to-severe ARDS, pulmonary vascular dysfunction on echocardiography, and PaCO ≥ 48 mmHg despite instrumental dead space reduction and the increase in respiratory rate.

Article Synopsis
  • * Out of 364 patients, 66.5% experienced poor functional outcomes after one year, with a significant portion (52.2%) having died, while age, comorbidities, initial coma score, and stroke type were key factors linked to worse outcomes.
  • * Notably, delays in starting mechanical ventilation after stroke diagnosis appeared to improve survival chances, and over half of the survivors reported ongoing physical and mental health issues one year later.

Background: The implantation of venovenous extracorporeal membrane oxygenation (VV-ECMO) support to manage severe acute respiratory distress syndrome generates large variations in carbon dioxide partial pressure (PaCO) that are associated with intracranial bleeding. We assessed the feasibility and efficacy of a pragmatic protocol for progressive dual titration of sweep gas flow and minute ventilation after VV-ECMO implantation in order to limit significant PaCO variations.

Patients And Methods: A protocol for dual titration of sweep gas flow and minute ventilation following VV-ECMO implantation was implemented in our unit in September 2020.

Background: Low-dose steroids are known to increase arterial pressure during septic shock through restoration of vasopressor response to norepinephrine. However, their effects on cardiac performance and ventriculo-arterial coupling (VAC) have never been scrutinized during human septic shock. The aim of this study was to perform a comprehensive description of the cardiovascular effects of low-dose steroids using modern echocardiographic tools (including speckle tracking imaging).

Background: The role of dobutamine during septic shock resuscitation is still controversial.

Methods: The aim of this prospective multicentre study was to comprehensively characterize the hemodynamic response of septic shock patients with systolic myocardial dysfunction to incremental doses of dobutamine (0, 5, 10, and 15 μg/kg/min).

Results: Thirty two patients were included in three centers.

Background: Right ventricular () dysfunction is associated with pulmonary vasoconstriction in mechanically ventilated patients. Enhancing the activity of angiotensin-converting enzyme 2 (2), a key enzyme of the renin-angiotensin system (), using recombinant human 2 (2) could alleviate -mediated vasoconstriction and vascular remodeling.

Methods: This prospective observational study investigated the association between concentrations of peptides (Ang II or Ang(1-7)) and markers of function, as assessed by echocardiography (ratio of to left ventricular end-diastolic area, interventricular septal motion, and pulmonary arterial systolic pressure ()).

Purpose: Acute kidney injury (AKI) is common in patients with COVID-19, however, its mechanism is still controversial, particularly in ICU settings. Urinary proteinuria profile could be a non-invasive tool of interest to scrutinize the pathophysiological process underlying AKI in COVID-19 patients. Material and Methods: We conducted a retrospective study between March 2020 and April 2020.

Background: Cardiogenic shock (CS) is a life-threatening condition characterized by circulatory insufficiency caused by an acute dysfunction of the heart pump. The pathophysiological approach to CS has recently been enriched by the tissue consequences of low flow, including inflammation, endothelial dysfunction, and alteration of the hypothalamic-pituitary-adrenal axis. The aim of the present trial is to evaluate the impact of early low-dose corticosteroid therapy on shock reversal in adults with CS.

Background: Veno-arterial Extracorporeal Life Support (V-A ECLS) has gained increasing place into the management of patients with refractory cardiogenic shock or cardiac arrest. Both surgical and percutaneous approach can be used for cannulation, but percutaneous approach has been associated with fewer complications. Angio-guided percutaneous cannulation and decannulation may further decrease the rate of complication.

Rationale: Acute respiratory failure (ARF) in patients admitted to the intensive care unit (ICU) with known or de novo small-vessel vasculitis (Svv) may be secondary to the underlying immune disease or to other causes. Early identification of the cause of ARF is essential to initiate the most appropriate treatment in a timely fashion.

Methods: A retrospective multicenter study in 10 French ICUs from January 2007 to January 2018 to assess the clinical presentation, main causes and outcome of ARF associated with Svv, and to identify variables associated with non-immune etiology of ARF in patients with known Svv.

Background: Critical illness-related corticosteroid insufficiency (CIRCI) is common during critical illness and is usually associated with poor outcomes, as prolonged duration of mechanical ventilation (MV) and higher mortality. CIRCI may alter cardiac and vascular functions. Weaning-induced pulmonary oedema (WiPO) is a major mechanism of weaning failure.
