BACKGROUND: Extracorporeal life support (ECLS) for cardiopulmonary resuscitation (CPR) may increase end organ perfusion and thus survival when conventional CPR fails. The aim was to investigate, if after ventricular fibrillation cardiac arrest in rodents ECLS improves outcome compared to conventional CPR. METHODS: In 24 adult male Sprague-Dawley rats (460 to 510 g) resuscitation was started after 10 min of no-flow with ECLS (consisting of an open reservoir, roller pump and membrane oxygenator, connected to a cannulas in the jugular vein and femoral artery, n = 8) or CPR (mechanical chest compressions plus ventilations, n = 8) and compared to a sham group (n = 8)...

Boulos S Nassar, Richard Kerber
Cardiac arrest continues to represent a public health burden with most patients having dismal outcomes. Cardiopulmonary resuscitation (CPR) is a complex set of interventions requiring leadership, coordination, and best practices. Despite the widespread adoption of new evidence in various guidelines, the provision of CPR remains variable with poor adherence to published recommendations. Key steps health care systems can take to enhance the quality of CPR and, potentially, to improve outcomes, include optimizing chest compressions; avoiding hyperventilation; encouraging intraosseus access, and monitoring capnography...

The purpose of cardiopulmonary resuscitation after sudden cardiac arrest is to restore minimal blood flow to provide oxygen to the brain and other vital organs. Chest compressions and external defibrillation are the first line for circulatory support. Although early defibrillation is the main factor influencing survival, cardiopulmonary resuscitation must be characterized by high-quality external chest compressions. Unfortunately, the performance of manual chest compressions decreases during time and in hostile conditions...

AIM: Chest compression devices are useful during mountain rescue but may cause a delay in transport if not immediately available. The aims of this prospective observational study were to compare manual and mechanical cardiopulmonary resuscitation (CPR) during transport on a sledge connected to a snowmobile with a non-moving setting and to compare CPR quality between manual and two mechanical chest compression devices. METHODS: Sixteen healthcare providers simulated four different combined CPR scenarios on a sledge in a non-moving setting and during transport and two mechanical chest compression devices during transport on the sledge...

BACKGROUND: Cardiopulmonary resuscitation (CPR) with the use of mechanical devices is recommended during ambulance transport. However, the CPR quality en route and while in transfer to the emergency department (ED) for out-of-hospital cardiac arrests (OHCAs) remains uncertain. We developed a mechanical CPR device outfitted on a reducible stretcher (M-CPR) and compared with standard manual CPR on a standard stretcher (S-CPR) to evaluate CPR quality. METHODS: Adult OHCAs transported by five ambulances in a metropolitan area with a population of 3...

In a healthy 12-year-old female with scoliosis, prone positioning resulted in pressor-refractory cardiovascular collapse. Resumption of supine position immediately improved hemodynamics. Intraoperative transesophageal echocardiography (TEE) revealed a collapsed left atrium and biventricular failure. Repeat prone positioning resulted in a recurrence of hypotension. However, hemodynamic stabilization was restored and maintained by repositioning chest pads caudally. The patient successfully underwent a 6-hour scoliosis repair without perioperative morbidity...

INTRODUCTION: High-quality cardiopulmonary resuscitation (CPR) is critical for successful cardiac arrest outcomes. Mechanical devices may improve CPR quality. We simulated a prehospital cardiac arrest, including patient transport, and compared the performance of the LUCAS™ device, a mechanical chest compression-decompression system, to manual CPR. We hypothesized that because of the movement involved in transporting the patient, LUCAS would provide chest compressions more consistent with high-quality CPR guidelines...

BACKGROUND: Mechanical chest compression devices may help to maintain high-quality cardiopulmonary resuscitation (CPR), but little evidence exists for their effectiveness. We evaluated whether or not the introduction of Lund University Cardiopulmonary Assistance System-2 (LUCAS-2; Jolife AB, Lund, Sweden) mechanical CPR into front-line emergency response vehicles would improve survival from out-of-hospital cardiac arrest (OHCA). OBJECTIVE: Evaluation of the LUCAS-2 device as a routine ambulance service treatment for OHCA...

INTRODUCTION: The LINC trial evaluated two ALS-CPR algorithms for OHCA patients, consisting of 3min' mechanical chest compression (LUCAS) cycles with defibrillation attempt through compressions vs. 2min' manual compressions with compression pause for defibrillation. The PARAMEDIC trial, using 2min' algorithm found worse outcome for patients with initial VF/VT in the LUCAS group and they received more adrenalin compared to the manual group. We wanted to evaluate if these algorithms had any outcome effect for patients still in VF/VT after the initial defibrillation and how adrenalin timing impacted it...

BACKGROUND: Potential cardiovascular benefits of precordial percussion pacing (PPP) during cardiac standstill are unknown.Methods and Results:A cardiac standstill model in amicrominipigwas created by inducing complete atrioventricular block with a catheter ablation technique (n=7). Next, the efficacy of cardiopulmonary resuscitation by standard chest compressions (S-CPR), PPP and ventricular electrical pacing in this model were analyzed in series (n=4). To assess the mechanism of PPP, a non-selective, stretch-activated channel blocker, amiloride, was administered during PPP (n=3)...

BACKGROUND: Performing advanced cardiac life support (ACLS) in the cardiac catheterization laboratory (CCL) is challenging. Mechanical chest compression (MCC) devices deliver compressions in a small space, allowing for simultaneous percutaneous coronary intervention and reduced radiation exposure to rescuers. In refractory cases, MCC devices allow rescuers to initiate percutaneous mechanical circulatory support (MCS) and extracorporeal life support (ECLS) during resuscitation. This study sought to assess the efficacy and safety of MCC when compared to manual compressions in the CCL...

Background Fatalities from acute compression have been reported with soft-drink vending machine tipping, motor vehicle accidents, and trench cave-ins. A major mechanism of such deaths is flail chest but the amount of force required is unclear. Between the range of a safe static chest compression force of 1000 N (102 kg with earth gravity) and a lethal dynamic force of 10-20 kN (falling 450 kg vending machines), there are limited quantitative human data on the force required to cause flail chest, which is a major correlate of acute fatal compression asphyxia...

Pectus excavatum (PE), the most common skeletal anomaly of chest wall, sometimes requires a surgical correction but recurrent PE is not uncommon. PE usually has a benign course; however, this chest deformity may be associated with symptomatic tachyarrhythmias due to mechanical compression. We report a case of a patient with recurrent PE after surgical correction presenting with palpitation and electrocardiogram (ECG) showing ST-segment elevation on the right precordial leads, which could be mistaken for a Brugada syndrome (BrS)...
