Cardiopulmonary Arrest

In the United States, the current standard of prehospital (i.e. outside of hospitals) emergency care for children with life-threatening illnesses in the community includes remote physician support for paramedics providing life-saving therapy while transporting the child to the hospital. Most prehospital emergency medical services (EMS) agencies use radio-based (audio only) communication between paramedics and physicians to augment this care. However, this communication strategy is inherently limited as the remote physician cannot visualize the patient for accurate assessment and to direct treatment. The purpose of this pilot randomized controlled trial (RCT) is to evaluate whether use of a 2-way audiovisual connection with a pediatric emergency medicine expert (intervention = "telemedical support") will improve the quality of care provided by paramedics to infant simulator mannequins with life threatening illness (respiratory failure). Paramedics receiving real-time telemedical support by a pediatric expert may provide better care due to decreased cognitive burden, critical action checking, protocol verification, and error correction. Because real pediatric life-threatening illnesses are rare, high stakes events and involve a vulnerable population (children), this RCT will test the effect of the intervention on paramedic performance in simulated cases of pediatric medical emergencies. The two specific aims for this research are: * Aim 1: To test the intervention efficacy by determining if there is a measurable difference in the frequency of serious safety events between study groups * Aim 2: To compare two safety event detection methods, medical record review, and video review

The NEURESCUE device is the first intelligent balloon catheter for aortic balloon occlusion (ABO), an emergency technique that supercharges blood flow to the heart and brain within one minute from deployment. The catheter-based device is delivered via the femoral artery, temporarily inflating a soft balloon in the descending to redirect blood flow towards the upper body. The purpose of this study is to compare the clinical safety and performance of Advanced Cardiovascular Life Support (ACLS) versus ACLS in combination with Aortic Balloon Occlusion (ABO) using the NEURESCUE device in subjects with cardiac arrest.

This is a prospective, observational, multi-center cohort study of pediatric cardiac arrests. The purpose of the study is to determine the association between chest compression mechanics (rate, depth, flow fraction, compression release) and patient outcomes. In addition, the investigators will determine the association of post cardiac arrest care with patient outcomes.

This study will be a prospective, single-center, randomized controlled trial in a tertiary pediatric emergency department with two parallel groups of voluntary pediatric physicians and nurses. The impact of a mHealth supportive tool will be compared with conventional communication methods on situational awareness, leadership, team communication effectiveness and performance during standardized, simulation-based, pediatric in-hospital cardiac arrest scenario using a high-fidelity manikin. Thirty-six participants will be randomized (1:1). The primary endpoint is the situational awareness score measured with the situation awareness global assessment technique (SAGAT) instrument.

Cognitive aids are decision support tools that present prompts to encourage recall of information, thus freeing up mental resources to increase the likelihood of desired behaviors. Cognitive aids have been trialed in different forms for use during resuscitation, including pocket reference cards and digital apps. Simulation-based studies of cognitive aid used during cardiac arrest events have shown improved adherence to guidelines, improved time to completing critical tasks, and reduced rate of critical errors. Unfortunately, existing pocket reference cards and mobile apps have significant flaws - they all require providers to search through content to identify relevant information. In the proposed study, the investigators will evaluate the impact of an enhanced system, InterFACE-AR, which provides role-specific decision support to the team leader and medication nurse through AR devices, while concurrently optimizing team situational awareness by displaying a roadmap for patient care on the LCD screen. Clinical data will be collected from the mobile app on a tablet used by the charting nurse. The trial aims to assess the individual and combined effectiveness of InterFACE-AR components (i.e. AR devices and LCD screen) on adherence to AHA resuscitation guidelines during simulated cardiac arrest by conducting a randomized controlled trial with a factorial design.

The investigators propose a multicenter randomized controlled trial in South Korea and Taiwan to observe the clinical effects of REBOA on nontraumatic out-of-hospital-cardiac-arrest (OHCA) patients. While REBOA has been traditionally used in trauma for hemorrhage control, it has also shown promising results in nontraumatic cardiac arrests by rerouting circulation to increase perfusion in the coronary and brain.

Long-term neurological outcome after successful resuscitation of cardiac arrest remains poor, mainly due to cerebral hypoperfusion and severe hypoxic-ischemic brain injuries. Automated head and chest elevation during cardiopulmonary resuscitation (AHUP-CPR) improves cerebral perfusion by decreasing the intracranial pressure and increasing cerebral perfusion in experimental pig studies. The addition of an impedance threshold device (ITD) and active chest compression-decompression device (ACD) improved hemodynamics and cerebral perfusion. In addition, early implementation of AHUP-CPR in patients with out-of-hospital cardiac arrest (OHCA) was associated with improved survival to hospital discharge, in a multicenter observational study. A 2-year prospective clinical trial in Grenoble evaluating this combination was just completed. This study showed for the first time that the value of end-tidal CO2 (EtCO2), a surrogate for cardiopulmonary resuscitation (CPR) quality and cardiac output, measured with this combination therapy, was significantly higher than with standard CPR. Resuscitative endovascular balloon occlusion of the aorta (REBOA) has recently been proposed during CPR. This technique temporarily diverts blood flow to the coronary and cerebral circulation. Its beneficial effect on hemodynamics, cerebral blood flow and survival has been experimentally validated. In several feasibility studies, encouraging results were observed by slightly optimizing cerebral perfusion and coronary pressure when REBOA was used in combination with standard CPR. In a porcine model of cardiac arrest, the addition of REBOA to AHUP CPR was associated with a marked improvement in coronary perfusion pressure and near-normalization of cerebral perfusion pressure. These two interventions act synergistically. REBOA directs flow and pressure to the heart and brain, while AHUP CPR improves preload on the right side of the heart and reduces intracranial pressure. The aims of this clinical investigation are to assess the feasibility of placing a REBOA catheter combined with automated CPR with head and chest elevation, and to quantify the associated changes in clinical parameters for OHCA.

We aim to investigate the effects of pre-arrest corticosteroid use for any reason on the time of return of spontaneous circulation in patients experiencing witnessed cardiac arrest, either in-hospital or out-of-hospital. Additionally, we plan to study the effects of corticosteroid use on post-ROSC administration of vasoactive agents, required dosage of vasoactive agents and number of vasoactive agents needed in order to reach targeted blood pressure levels.
