Filter by:This study will compare the effect of constant low-level energy [150 joules] to an escalating energy [200-300-360 joules] regimen of biphasic waveform defibrillation on multiple patient outcomes.
The purpose of the study is to evaluate the incremental benefit of a full advanced life support EMS program on the outcomes of chest pain, respiratory and major trauma patients.
Airway control and ventilation is vital during cardiopulmonary resuscitation (CPR) in cardiac arrest. Endotracheal intubation is the gold standard for airway control, but several studies have shown high rates of unrecognized placements of the tube in the esophagus instead of in the airway out-of-hospital. This is lethal. There are no failproof technique for recognising such mistakes clinically in the cardiac arrest situation. Changes on the air volume in the lungs with ventilation changes the impedance (resistance to alternating current) through the thorax. This impedance is already measured routinely by the defibrillators used during CPR. We propose that we can measure ventilation volumes and also discover failed intubations by monitoring this impedance during CPR with the possibility of giving feedback on both to the rescuers.
The purpose of this study is to determine whether performing active compression decompression cardiopulmonary resuscitation (ACD-CPR) with an impedance threshold device (ITD) compared to conventional standard cardiopulmonary resuscitation (S-CPR) will impact the neurologic recovery and survival to hospital discharge following out-of-hospital cardiac arrest.
The purpose of this study is to evaluate the strategy of implanting an ICD with or without EPS before, during and after ICD-implantation in a randomised controlled trial, using a combined endpoint of major ICD-related adverse events as the primary outcome measure.
Analysis of the patients' data who were rescued with extracorporeal membrane oxygenation and without ECMO. The survival rate and the weaning rate were analyzed to see the effect of ECMO on the prolonged CPR.
Out-of-hospital cardiac arrest (OHCA) is an important issue for the emergency physicians and co-workers. How to improve the return of spontaneous circulation (ROSC) rate and prognosis of these patients challenges the emergency team. When encounters stress, the hypothalamus of human releases corticotropin releasing hormone, which in turn stimulates the pituitary gland to release ACTH. Then ACTH acts on the adrenal gland to release glucocorticoid to against stress. Foley PJ et al found the dogs with bilateral adrenalectomy had lower ROSC rate during resuscitation than those without surgery[1]. Karl H. Linder et al showed OHCA patients had high serum vasopressin and ACTH level but low serum cortisol level. Besides, the serum cortisol level had a negative correlation with collapse duration (no CPR duration)[2]. Studies also revealed the successfully resuscitated patients had higher serum ACTH and cortisol level than non-resuscitated ones[2,3]. In addition, the serum cortisol level was found to be correlated with short term survival rate and hemodynamic status in resuscitated OHCA patients[3]. Animal study also showed mice receiving higher dosage of hydrocortisone had higher ROSC rate and lower epinephrine requirement than those receiving lower dosage of hydrocortisone or normal saline. <Reference> 1.

The general aim of this study is to compare the efficacy and safety of tenecteplase to standard treatment during cardiopulmonary resuscitation in patients suffering from out-of-hospital cardiac arrest.
Hypothermic resuscitation is proven to be benefit to the cardiac origin cardiac arrest patients for it improve brain recovery dramatically. However, traditional cooling devices and methods, most external cooling methods, include ice blanket, cooling helmet, or ice packing lower the body temperature slowly or inefficiently which make many emergency physicians hesitate to perform hypothermic resuscitation. To improve and promote the practice of hypothermia resuscitation, more efficient temperature control method is necessary. We conduct this clinical trial to evaluate the safety and feasibility of internal cooling catheter and temperature regulatory device, which is approved by FDA in neurologic ICU for temperature control, in the cardiac arrest patients.
The aim of the trial is to evaluate a new AED algorithm that proposes a new timeline between the time devoted to administer a defibrillation shock, and the time devoted to chest compressions. The researchers propose to decrease the periods of interruption of cardiopulmonary resuscitation (CPR), while keeping the principle of early defibrillation.
