Active clinical trials for "Heart Arrest"

This Phase 2 study aims to determine the feasibility of paramedic titration of oxygen delivery in adult patients who have been resuscitated from OHCA.

The aim of this randomized out-of-hospital cardiopulmonary resuscitation study is to investigate haemodynamics generated by the standard mechanical external chest compression device (LUCAS™ 2) compared to a new version generating chest compressions and active decompression above the initial starting position of the suction cup (LUCAS™ 2AD).

Objective: Safety and efficacy of low-dose prostacyclin administration and blood pressure target in addition to standard therapy, as compared to standard therapy alone, in post-cardiac-arrest-syndrome (PCAS) patients.

The purpose of this study is to estimate the effect of medical treatment of electro-encephalographic status epilepticus on neurological outcome of patients with postanoxic encephalopathy after cardiac arrest.

The objective of this study will be to assess the frequency of return of spontaneous circulation (ROSC), survival to admission, survival to discharge from the hospital, and neurologic function at time of discharge from the hospital among patients experiencing out of hospital cardiac arrest randomized to receive either intra-arrest induction of therapeutic hypothermia (IATH) or post-arrest therapeutic hypothermia (TH).

In patients with out-of-hospital cardiac arrest in Singapore, investigators aim to assess the benefit of introducing a resuscitation protocol including the use of intravenous (IV) access and/or intraosseous (IO) vascular access in the pre-hospital setting. The assumption is that low vascular access rates could be due to difficulty of setting IV cannulas in the field due to certain factors like poor lighting or space constraints. Thus, by introducing a protocol including IO access for difficult IV cases, success rates for vascular access will be higher and this might lead to higher survival rates. This will be a study comparing 'IV+IO' and 'IV alone' protocols in patients with cardiac arrest managed by Singapore Civil Defence Force (SCDF) emergency ambulance service. The trial will recruit 400 patients over 1 year. Each of the 30 SCDF ambulances will provide both 'IV+IO' and 'IV alone' treatments in 2 consecutive phases of 6-months in order to allow for all ambulance crew a chance to be trained on usage of IO. Currently, IO insertion is the accepted standard of care in Singapore General Hospital, Department of Emergency Medicine.

Mild therapeutic hypothermia is currently recommended in management of cardiac arrests with shockable rhythm. In mechanically ventilated patients who were resuscitated after out-of-hospital cardiac arrests, mild therapeutic hypothermia side effects are conductive for infectious complications and especially for ventilator-associated pneumonia (VAP). Despite high incidence of VAP and other infectious complications, it is not currently recommended to use antibiotic prophylaxis on the responsible germs. Yet VAP incidence could be decreased if an antibiotic therapy was systematically given to patient treated with mild therapeutic hypothermia after a cardiac arrest. Several retrospective studies showed less infectious complications but also decreased morbidity and mortality related to these complications when antibiotic therapy was given early to patients treated with therapeutic hypothermia after cardiac arrest.

The main purpose of this study is to explore whether xenon is neuroprotective in humans. In addition, the purpose is to explore the underlying mechanisms for the possible synergistic neuroprotective interaction of xenon and hypothermia in patients suffering cerebral ischemia post cardiac arrest, by undertaking brain imaging to evaluate their effects on cerebral hypoxia, neuronal loss and mitochondrial dysfunction. In addition, the investigators aim to correlate these findings with neurological outcome to determine surrogate markers of favourable clinical outcome at six months.

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.

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.
