Filter by:To evaluate the effect of use of automated chest compression device on blood pressure in patients presenting with cardiac arrest. Higher systolic, diastolic and mean blood pressures are expected.
Automated external defibrillators have improved survival for adult in hospital cardiac arrest. Automated external defibrillators are approved for children aged 1 year and older for out of hospital cardiac arrests. It is unknown whether automated external defibrillators have a role for in hospital pediatric cardiac arrests. The purpose of study is to compare the management of cardiac rhythm disorders by pediatric residents using an automated external defibrillator versus a standard defibrillator in simulated pediatric cardiac arrests. It is our hypothesis that residents using an automated external defibrillator will have a shorter time to defibrillation.
The design of this protocol is a prospective observational study to objectively measure the rate, depth and quality of chest compressions and ventilations delivered during cardiac arrest in the Pediatric Intensive Care Unit (PICU) and Emergency Department (ED) settings utilizing the MRx/Q-CPR. The data collected will be analyzed for several purposes - for comparison with current American Heart Association (AHA) Cardiopulmonary Resuscitation (CPR) guidelines and to determine chest wall stiffness for CPR modeling efforts and construction of biofidelic manikins or test dummies for CPR and auto safety.
Cardiac arrest has a very poor prognosis, especially with prolonged efforts at resuscitation, and unfortunately, survivors are often severely neurologically impaired. CPA in children is often the result of a prolonged illness rather than a sudden, primary cardiac event as is frequent in adults. This necessitates that resuscitation research must be conducted separately for pediatric and adult patients. Authorities currently endorse the use of epinephrine for restoring spontaneous circulation based on its ability to maintain diastolic blood pressure and subsequent blood flow to the heart during resuscitation. However, human studies have shown no clear survival benefit of epinephrine and have elucidated concerning adverse effects. Recently, both the European Resuscitation Council and the American Heart Association have recognized the use of vasopressin as a promising vasoconstrictor and an alternative or adjunct to epinephrine in the resuscitation of adults. Vasopressin causes profound vasoconstriction without the adverse effects of epinephrine and is associated with improved blood flow to the heart and brain. This increased cerebral blood flow has been associated with better neurologic outcome in animal studies. In light of compelling animal and human studies of combined vasopressin and epinephrine, pediatric trials are indicated for vasopressin usage in pediatric CPR. This study will evaluate the addition of the administration of vasopressin to standard advanced CPR therapy (epinephrine alone) for pediatric patients that experience in-intensive care unit CPA to assess for improved time to return of spontaneous circulation (ROSC), survival to 24 hours, survival to hospital discharge, and neurologic outcome. When a patient experiences a CPA, standard Pediatric Advanced Life Saving (PALS) protocols as endorsed by the American Heart Association will be initiated. This will include receiving epinephrine as the first vasopressor medication. Patients will then be randomized to receive vasopressin (treatment group) or epinephrine (control group) as the second vasopressor medication, if needed. If more then two doses of vasopressor medication is required in either group, epinephrine will be administered according to the PALS algorithm until the end of the event. All CPA events meeting inclusion criteria will be entered into the National Registry of Cardiopulmonary Resuscitation (NRCPR) Database, which tracts all CPA events at Children's Medical Center Dallas. Prior to commencement of the RCT, a pilot trial of 10 patients will be completed to assess preliminary safety, feasibility, and effectiveness of combination epinephrine-vasopressin for pediatric in-intensive care unit CPA refractory to initial epinephrine dosing. All pilot patients will receive vasopressin as the second vasopressor medication.
Patients resuscitated from a cardiac arrest undergo therapeutic hypothermia as a treatment option. Measuring the cardiac output in these patients is sometimes important, but difficult, as these patients require an invasive device for measurement. Recently, a non-invasive device based on pulse-contour analysis of the arterial pulse was developed (the Vigileo). Hypothermia changes the pulse contour, so the performance of the Vigileo in patients with induced therapeutic hypothermia is not known. Therefore we conduct this observational study in which the cardiac output of the patients is measured with the traditional method and the Vigileo simultaneously.
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 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.
The purpose of this study is to evaluate whether or not real-time feedback on CPR process variables will increase rates of restoration of spontaneous circulation during prehospital resuscitation and upon arrival at the receiving emergency room as well as increase rates of survival to hospital discharge.
This study is designed to examine the impact of an available technology within an automated external defibrillator (AEDs) to improve survival following out-of-hospital cardiac arrest for patients presenting in ventricular fibrillation.
