Filter by: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).
1. Pre-shock cardiopulmonary resuscitation might benefit the survival of out-of-hospital cardiac patients with ventricular fibrillation / ventricular tachycardia in a post-hoc analysis of a prehospital trial conducted in Europe (L.Wik,2002). However, it's effectiveness in the Asian countries, where most firstly recorded rhythm in out-of-hospital cardiac arrests patients were asystole/pulseless electric activity rather than ventricular fibrillation / ventricular tachycardia, were not explored yet. 2. This trial was designed to exam if pre-shock cardiopulmonary resuscitation by emergency medical technicians improves the outcome of all out-of-hospital cardiac arrest patients in an Asian metropolitan city.
Sudden death is a major problem in industrially developed countries. Despite a decline in ischemic heart disease mortality and the progress has been made in resuscitation, treatment of sudden death victims is frequently unsuccessful. the ideal solution would be to prevent the disease process that causes the initial episode of cardiac arrest. Parental sudden death is an independent risk factor for sudden death. So, detect a gene predisposing to sudden death may help provide better identification of subjects at high risk of cardiac arrest. This research is a genetic study of sudden cardiac death, recruited 2000 subjects in out-of-hospital cardiac arrest.
During resuscitation of out of hospital cardiac arrest patients the use of a mechanical chest compression device Autopulse will improve survival compared to manual compressions.
The overall goal of this study is to determine whether initiating hypothermia in cardiac arrest patients as soon as possible in the field results in a greater proportion of patients who survive to hospital discharge compared to standard prehospital/field care.
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 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.
Recent studies have suggested that arginine-vasopressin could be more effective in the treatment of cardiac arrests. The last published study did not outline obvious improvements in the prognosis of all cardiac arrests but pointed out a possible increased survival rate when arginine-vasopressin is associated with epinephrine. The aim of this study is to compare the efficacy of two successive injections of epinephrine (1 mg) with two successive injections of epinephrine associated with arginine-vasopressin (40 UI) in out-of-hospital cardiac arrests occurring in adult patients. The primary endpoint is the survival rate at hospital admission. The inclusion period lasts 18 months and 2416 patients are planned to be enrolled.
