Metabolomic profiling of cardiac allografts after controlled circulatory death.

Background: Assessment of myocardial viability during ex situ heart perfusion (ESHP) is based on the measurement of lactate concentrations. As this provides with limited information, we sought to investigate the metabolic signature associated with donation after circulatory death (DCD) and the impact of ESHP on the myocardial metabolome.

Methods: Porcine hearts were retrieved either after warm ischemia (DCD group, N = 6); after brain-stem death (BSD group, N = 6); or without DCD nor BSD (Control group, N = 6).

Extubation Failure Prediction by Echography of the Diaphragm After Cardiothoracic Surgery: The EXPEDIA Study.

Background: Successful extubation is difficult to predict. Ultrasound measurement of the diaphragm thickening fraction (DTF) might help predict weaning failure after cardiothoracic surgery.

Methods: We assessed the predictive performance of diaphragm ultrasound in a derivation cohort of 50 prospectively included cardiothoracic surgery subjects ready for a weaning trial and in a validation cohort of 39 subjects ventilated for ≥ 48 h.

Ex vivo perfusion of the donor heart: Preliminary experience in high-risk transplantations.

Background: The number of heart transplantations (HTs) has decreased in France since 2017 (-5%/year) despite a stable rate of patients referred on the waiting list. Ex vivo heart perfusion (EVHP) is an innovative approach for organ preservation, reducing graft ischaemic time and facilitating continuous organ monitoring before transplantation.

Aim: To report our preliminary experience of seven donor hearts preserved with EVHP, including the first heart resuscitated after circulatory-determined death in France.

Effect of Recruitment Maneuvers and PEEP on Respiratory Failure After Cardiothoracic Surgery in Obese Subjects: A Randomized Controlled Trial.

Background: Obesity may increase the risk of respiratory failure after cardiothoracic surgery. A recruitment maneuver followed by PEEP might decrease the risk of respiratory failure in obese subjects. We hypothesized that the routine use after heart surgery of a recruitment maneuver followed by high or low PEEP level would decrease the frequency of respiratory failure in obese subjects.

Lung and heart-lung transplantation for children with PAH: Dramatic benefits from the implementation of a high-priority allocation program in France.

Purpose: Pulmonary arterial hypertension (PAH) is rare but remains fatal in infants and children despite the advance of targeted therapies. Lung transplantation (LTx), first performed in pediatric patients in the 1980s, is, with the Potts shunt, the only potentially life-extending option in patients with end-stage PAH but is possible only in tightly selected patients. Size-matching challenges severely restrict the donor organ pool, resulting-together with peculiarities of PAH in infants-in high waitlist mortality.

Specific Considerations for Venovenous Extracorporeal Membrane Oxygenation During Coronavirus Disease 2019 Pandemic.

Extracorporeal membrane oxygenation (ECMO) is recognized as organ support for potentially reversible acute respiratory distress syndrome (ARDS). However, limited resource during the outbreak and the coagulopathy associated with coronavirus disease 2019 (COVID-19) make the utilization of venovenous (VV) ECMO highly challenging. We herein report specific considerations for cannulation configurations and ECMO management during the pandemic.

Neuromuscular Blockade Monitoring in Acute Respiratory Distress Syndrome: Randomized Controlled Trial of Clinical Assessment Alone or With Peripheral Nerve Stimulation.

Background: Whether train-of-four (TOF) monitoring is more effective than clinical monitoring to guide neuromuscular blockade (NMB) in patients with acute respiratory distress syndrome (ARDS) is unclear. We compared clinical monitoring alone or with TOF monitoring to guide atracurium dosage adjustment with respect to drug dose and respiratory parameters.

Methods: From 2015 to 2016, we conducted a randomized controlled trial comparing clinical assessments every 2 hours with or without corrugator supercilii TOF monitoring every 4 hours in patients who developed ARDS (Pao2/Fio2 <150 mm Hg) in a cardiothoracic intensive care unit.

Ultrasound Assessment of Respiratory Workload With High-Flow Nasal Oxygen Versus Other Noninvasive Methods After Chest Surgery.

Objective: To compare the respiratory workload using the diaphragm thickening fraction (DTf) determined by sonography during high-flow nasal oxygen (HFNO), standard oxygen therapy (SOT), and noninvasive bilevel positive airway pressure support (BIPAP) in patients with acute respiratory failure (ARF) after cardiothoracic surgery.

Design: Prospective controlled clinical trial.

Setting: A French 23-bed cardiothoracic surgical intensive care unit.

Connection of a Renal Replacement Therapy or Plasmapheresis Device to the ECMO Circuit.

In patients under extracorporeal membrane oxygenation (ECMO) support requiring renal replacement therapy or plasmapheresis, connecting such extracorporeal therapy device to the ECMO circuit provides many advantages compared with central venous catheterization. However, high pressures of the ECMO circuit limit the usefulness of this technique. We propose a new approach to connect extracorporeal therapy lines to the ECMO circuit.

Evaluation of Reperfusion Pulmonary Edema by Extravascular Lung Water Measurements After Pulmonary Endarterectomy.

Objectives: Reperfusion pulmonary edema is a specific complication of pulmonary endarterectomy for chronic thromboembolic pulmonary hypertension. Extravascular lung water measurement may be valuable for diagnosing reperfusion pulmonary edema. The primary objective of this study was to describe and assess the clinical significance of extravascular lung water variations after pulmonary endarterectomy.

Fiber optic bronchoscopy and remifentanil target-controlled infusion in critically ill patients with acute hypoxaemic respiratory failure: A descriptive study.

Introduction: Sedation optimizes patient comfort and ease of execution during fiber optic bronchoscopy (FOB). Our objective was to describe the safety and efficacy of remifentanil-TCI during FOB in non-intubated, hypoxaemic, thoracic surgery ICU patients.

Methods: Consecutive spontaneously breathing adults requiring FOB after thoracic surgery were included if they had hypoxaemia (PaO/FiO<300mmHg or need for non-invasive ventilation [NIV]) and prior FOB failure under topical anaesthesia.

[Fatal Panton-Valentine leukocidine-associated Staphylococcus aureus necrotizing pneumonia].

Panton-Valentine leukocidin-producing Staphylococcus aureus necrotizing pneumonia is an unusual cause of community-acquired pneumonia associated with a high fatality rate. The specificities of its presentation must be known by the critical care doctor, in order to quickly make the diagnosis and start the right antibiotics and discuss adjunctive therapy with intravenous immunoglobin. Moreover, the management of close contacts (household and healthcare workers) of patient with such a pneumonia is not well-known.

[Impact of the decrease of nitrous oxide use on the consumption of halogenated agents].

Objective: Nitrous oxide (N2O) toxicity and its impact on pollution lead to restrict its use. A decrease of N2O consumption should increase the hypnotic inhaled consumption. This monocentric study estimated consumptions and costs of halogenated agents (HA) and N2O over 5 years when the N2O consumption was reduced.
