Active clinical trials for "Heart Arrest"

The primary aim of the trial is to compare survival to hospital discharge after continuous chest compressions (CCC) versus standard American Heart Association (AHA) recommended cardiopulmonary resuscitation (CPR) with interrupted chest compressions (ICC) in patients with out-of-hospital cardiac arrest (OOHCA). The primary null hypothesis will be that the rate of survival to hospital discharge is not affected by use of continuous compressions with passive or positive pressure ventilation (intervention group) versus CPR with compressions interrupted for ventilation at a ratio of 30:2 (control group).

The purpose of this study is to test the possible neuroprotective effect of early high dose erythropoietin alpha after out of hospital cardiac arrest (OHCA).

Cardiac arrest is a sudden, unexpected loss of heart function. Therapeutic hypothermia, in which the body's temperature is lowered and maintained several degrees below normal for a period of time, has been used to successfully treat adults who have experienced cardiac arrest. This study will evaluate the efficacy of therapeutic hypothermia at increasing survival rates and reducing the risk of brain injury in infants and children who experience a cardiac arrest while out of the hospital.

Experimental studies and previous clinical trials suggest an improvement in mortality and neurological function with hypothermia after cardiac arrest. However, the accrued evidence is inconclusive and associated with risks of systematic error, design error and random error. Elevated body temperature after cardiac arrest is associated with a worse outcome. Previous trials did not treat elevated body temperature in the control groups. The optimal target temperature for post-resuscitation care is not known. The primary purpose with the TTM-trial is to evaluate if there are differences in all-cause mortality, neurological function and adverse events between a target temperature management at 33°C and 36°C for 24 hours following return of spontaneous circulation after cardiac arrest.

The purpose of this study is to determine whether adding interactive video communication to dispatch instruction improves the quality of bystander cardiopulmonary resuscitation in simulated cardiac arrests.

We propose to randomize automatic external cardioverter/defibrillators (AECD) in patients who are at high risk for life-threatening abnormal heart rhythms (arrhythmias) and are admitted to the telemetry ward, all other treatments being constant including cardiopulmonary resuscitation. We hypothesize that the automatic, rapid, accurate and specific diagnostic and therapeutic technology used in AECDs will further increase the rate of survival in patients with cardiac arrest through rapid and automatic defibrillation, independent of operator initiation, as compared to standard cardiopulmonary resuscitation initiated by healthcare providers.

The broad objective of this study is to test the association between hyperoxia exposure after resuscitation from cardiac arrest and outcome. After obtaining written informed consent subjects enrolled in REOX II will undergo a rapid faction of inspired oxygen (FiO2) optimization protocol to prevent exposure to hyperoxia. We will compare outcomes between subjects enrolled in REOX I (observational study only) and REOX II (intervention: rapid FiO2 optimization protocol). Our overarching hypothesis is that exposure to hyperoxia after return of spontaneous circulation (ROSC) is associated with increased oxidative stress and worsened neurological and cognitive outcomes.

Introduction: The laryngeal mask airway (LMA) is used as the primary airway by paramedics in Singapore Civil Defense Force's Emergency Ambulance Service (SCDF's EAS) in the management of out-of-hospital cardiac arrest, because endotracheal intubation requires skilled and experienced personnel, and local paramedics are not trained to this level of skill and competency. However, self-reported insertion success rates by paramedics in the field are currently only about 50-87%. Devices like the laryngeal tube have been shown to have higher placement success rates and fewer complications. Aim: Investigators aim to evaluate the efficacy and safety of a new device, the Laryngeal Tube (LT), compared to the LMA. They hypothesize that the LT is superior to the LMA in terms of placement success rates by paramedics in SCDF's EAS, and is associated with fewer adverse events. Methodology: Investigators propose to conduct a prospective, longitudinal multi-centre randomized trial comparing LMA and LT in patients with cardiac arrest (medical or traumatic) managed by SCDF EAS. The trial will recruit 1,015 eligible patients presenting to SCDF irrespective of destination hospital over a period of 1 year to detect an expected 15% difference in placement success rate. Currently the LMA is used as standard of care by SCDF's EAS in patients with cardiac arrest. Results: Besides the primary outcome, the secondary outcomes of dislodgment rates, time to placement, number of attempts and adverse events will be analyzed and will be useful in guiding future SCDF cardiac arrest protocols.

This study must evaluate the benefit of a continuous audio guidance on the effectiveness of MCE directed by a volunteer. The evaluation of the MCE for this study is based on both quantitative criteria (based on the recommendations ERC 2010) frequency depth of chest compressions. This study compares two methods of continuous audio guide (one arm with an audio continuous guidance method by the regulator and second arm with an audio continuous guidance method by the controller relayed by an audio) to a method of incentive MCE based on a unique set made by the regulator(control arm).

the international recommendations don't explain the place of the intraosseous infusion in the reanimation of adult cardiac arrest; the goal of this preliminary study is to inform the delay for obtaining a vascular access by evaluation of a current strategy (using intraosseous infusion after one peripheral venous access failure) and to determine the potential failure risk factors of venous access.
