Background: Inter-facility transport of patients with acute respiratory distress syndrome (ARDS) in the prone position (PP) is a high-risk situation, compared to other strategies. We aimed to quantify the prevalence of complications during transport in PP, compared to transports with veno-venous extracorporeal membrane oxygenation (VV-ECMO) or in the supine position (SP).
Methods: We performed a retrospective, single center cohort study in Lyon university hospital, France.
Impacts of chest compression cycle length and real-time feedback with a CPRmeter® on chest compression quality in out-of-hospital cardiac arrest: study protocol for a multicenter randomized controlled factorial plan trial.

July 2020
Background: With a survival rate of 6 to 11%, out-of-hospital cardiac arrest (OHCA) remains a healthcare challenge with room for improvement in morbidity and mortality. The guidelines emphasize the highest possible quality of cardiopulmonary resuscitation (CPR) and chest compressions (CC). It is essential to minimize CC interruptions, and therefore increase the chest compression fraction (CCF), as this is an independent factor for survival.

We sought to assess the frequency and effect of an optimal therapy upon discharge according to current international guidelines on 1-year all-cause mortality in a prospective cohort of reperfused patients with STEMI. Using data from the French Reseau Cardiologie Urgence (RESCUe) Network, we studied all patients with STEMI admitted and discharged alive from hospital between 2009 and 2013.

- Cyclosporine may help reduce the negative effects of systemic ischemia reperfusion following cardiac arrest, potentially preventing multiple organ failure in patients after out-of-hospital cardiac arrest (OHCA).
- A clinical trial known as CYRUS tested the early administration of cyclosporine during resuscitation in 6758 patients across multiple hospitals in France from 2010 to 2013, evaluating its impact on organ function and survival.
- The study found no significant difference in organ failure scores 24 hours post-admission between patients who received cyclosporine and those who did not, indicating that standard resuscitation methods alone may not be improved by the drug in this context.
Background: The main objective of this study was to compare the volume of gas insufflated in the stomach with continuous external chest compressions plus continuous oxygen insufflation (C-CPR) versus standard-CPR (S-CPR) which alternates external chest compressions and synchronized positive insufflations through a bag-valve-mask with a 30/2 ratio. The secondary objective was to compare upper airway pressures (intratracheal and intramask) generated during continuous oxygen insufflation.
Material And Methods: Open, prospective, randomized, cross over, comparative, non-inferiority study.
Background: Compared with administration in the catheterization laboratory, early treatment with glycoprotein IIb/IIIa inhibitors provides benefits to patients with ST-segment elevation myocardial infarction who undergo primary percutaneous intervention. Whether this benefit is maintained on top of a 600 mg loading dose of clopidogrel is unknown.
Methods: In a multicentre, controlled, randomized study, 320 patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention received a high-dose bolus of tirofiban given either in the ambulance (prehospital group) or in the catheterization laboratory.
Aims: The CAPTIM (Comparison of primary Angioplasty and Pre-hospital fibrinolysis In acute Myocardial infarction) study found no evidence that a strategy of primary angioplasty was superior in terms of 30-day outcomes to a strategy of pre-hospital fibrinolysis with transfer to an interventional facility in patients managed early at the acute phase of an acute myocardial infarction. The present analysis was designed to compare both strategies at 5 years.
Methods And Results: The CAPTIM study included 840 patients managed in a pre-hospital setting within 6 h of an acute ST-segment elevation myocardial infarction.
Background: During the administration of advanced cardiac life support for resuscitation from cardiac arrest, a combination of vasopressin and epinephrine may be more effective than epinephrine or vasopressin alone, but evidence is insufficient to make clinical recommendations.
Methods: In a multicenter study, we randomly assigned adults with out-of-hospital cardiac arrest to receive successive injections of either 1 mg of epinephrine and 40 IU of vasopressin or 1 mg of epinephrine and saline placebo, followed by administration of the same combination of study drugs if spontaneous circulation was not restored and subsequently by additional epinephrine if needed. The primary end point was survival to hospital admission; the secondary end points were return of spontaneous circulation, survival to hospital discharge, good neurologic recovery, and 1-year survival.
After publication of the 2005 international recommendations on resuscitation, a French panel of experts on cardiac arrest published guidelines adapted to French practice. Despite the absence of placebo-controlled trials, adrenaline remains the standard vasopressor for cardiac arrest, at a dose of 1 mg about every 4 minutes. Amiodarone has replaced lidocaine in treatment of refractory ventricular fibrillation.

Our aim was to compare the outcome of patients with traumatic or nontraumatic ("medical") out-of-hospital cardiac arrest.
Design: Cohort analysis of patients with out-of-hospital cardiac arrest included in the European Epinephrine Study Group's trial comparing high vs.
Aims: The CAPTIM study randomized patients managed within 6 h of acute ST-segment elevation myocardial infarction to primary angioplasty or prehospital fibrinolysis (rt-PA), with immediate transfer to a centre with interventional facilities. It found a similar incidence of the primary endpoint of death, recurrent MI, or stroke at 30 days with both strategies. We report here the outcome in the diabetic subgroup.
View Article and Find Full Text PDFBackground: CAPTIM was a randomized trial comparing prehospital thrombolysis with transfer to an interventional facility (and, if needed, percutaneous intervention) with primary percutaneous coronary intervention (PCI) in patients with ST-segment-elevation myocardial infarction (STEMI). Because the benefit of thrombolysis is maximal during the first 2 hours after symptom onset, and because prehospital thrombolysis can be implemented earlier than PCI, this analysis studied the relationship between the effect of assigned treatment and the time elapsed from symptom onset.
Methods And Results: Randomization within 2 hours (n=460) or > or =2 hours (n=374) after symptom onset had no impact on the effect of treatment on the 30-day combined primary end point of death, nonfatal reinfarction, and disabling stroke.
Background: Although both prehospital fibrinolysis and primary angioplasty provide a clinical benefit over in-hospital fibrinolysis in acute myocardial infarction, they have not been directly compared. Our aim was to find out whether primary angioplasty was better than prehospital fibrinolysis.
Methods: We did a randomised multicentre trial of 840 patients (of 1200 planned) who presented within 6 h of acute myocardial infarction with ST-segment elevation, initially managed by mobile emergency-care units.
