Filter by:Cardiac arrest (CA) is a major public health problem (1) because of its frequency (30000 to 50000 new cases of CA per year in France), a high mortality 80-90% and a relevant morbidity : 50% of survivors have cerebral sequela. Neurologic prognostication after CA is paramount. The American Academy of Neurology identifies accurate predictors of poor neurologic outcome (2): clinical examination findings such as no pupil response, no corneal reflexes, no motor response to stimulation and early myoclonus status epilepticus; biologic parameters like high neuron specific enolase (NSE) greater than 33 μg/L (3-4) and electrophysiologic results like flat electroencephalogram (EEG) or with burst suppression and Somatosensory evoked potentials (SEP) with no response to N20. Brain imaging may provide additional informations but not recommended yet. However, these pronotic markers were developed before the introduction therapeutic hypothermia (TH) (5-6). TH is now recommended after cardiac arrest by international guidelines, based on demonstration of improved survival and neurological recovery in comatose survivors of CA (7). TH and its associated use of sedative and paralytic agent may delay neurologic recovery and affect the optimal timing of prognostic variables (8). Many classifications of electroencephalogram (EEG) (9-12) exist but no one is generally accept and recommended and they were created before TH. In a preliminary study based on a retrospective cohort of 64 patients in CA with initial TH, we developped an electroencephalographic score to predict precocity the neurologic outcome according to the Cerebral performance category (CPC) (13-14). The purpose of this study is to evaluate a simple and objective electroencephalographic score helpful to predict neurologic outcome after CA. Then, we would like to create a composite score to have a multimodal prognostication. Patients and methods After CA resuscitation, all patients underwent coronary angioplasty if indicated and then were immediately admitted in emergency room of ICU. All patients were intubated and mechanically ventilated. Sedation was performed with continuous infusion of midazolam 0,15-0,2 mg/kg/h and sufentanil 0,15-0,2 μg/kg/h. All our patients were curarized with cisatracurium 0,2-0,3 mg/kg/h to prevent shivering during TH and took anti-epileptic medication phenobarbital 10-15 mg/ kg two times a day to prevent infra-clinic convulsive seizure. Mild TH between 33 -34 °C was performed by active cooling with intravascular device (CoolGard® - Zoll, Chelmsford, UK) for 24 hours. Mean arterial pressure was maintained between [75-80] mmHg by titrated norepinephrine with or without inotropics (dobutamine, epinephrine) according cardiac output monitored by echocardiography. After 24 hours of hypothermia, warming was started at a rate of 0.2 ° C/hr; neuromuscular blocking agents were arrested at 35.5°C and sedation at 36.5°C. Neurological evaluation performed at 48 hours off sedation included a clinical evaluation (Glasgow score, myoclonus status, response to orders, motor response to stimulation, brain-stem reflexes). NSE was sampled between 48 and 72 H. EEGs were performed at Day-2, Day-3 and Day-5 off sedation and SEP at Day-5 off sedation. All EEGs were interpreted by two certified electroencephalographers blind from clinical neurologic outcome. Survival and neurologic outcome according to CPC were assessed at ICU discharge and three months later.
In the last ten years patient safety during routine surgical interventions has increased; however as there is an increase in the number of specialized surgical interventions and high risk patients like elderly and emergency patients, the incidence of perioperative cardiac arrest has not reduced but remains fixed. The incidence of perioperative cardiac arrest varies from 4.3-34.6 for each 10,000 procedures. However as in a lot of other countries exact data are lacking also for Turkey. With this study the investigators want to start collecting data about intraoperative cardiac arrest in Turkey, starting at their institution The aim is to evaluate the incidence and outcome in the study. Secondary aim is to assess the causes of cardiac arrest in the operating room.
Cerebral saturation will be measured pre-hospital during an out-of hospital cardiac arrest with O3TM regional oximetry for Root® (Masimo®). The O3TM regional oximetry for Root® (Masimo®) is a device that can measure not only cerebral saturation but also end-tidal CO2 (capnography). Currently, end-tidal CO2 is already measured during Advanced Life Support following most recent European Resuscitation Guidelines but with another monitor. Until now it is the only parameter which may predict return of spontaneous circulation. Because of this, researchers want to measure both with the same device, which gives the investigators the opportunity and advantage to compare end-tidal CO2 and cerebral saturation very precisely. In this manner researchers want to investigate the predictive value of cerebral saturation and compare it end-tidal CO2.
Therapeutic hypothermia after out-of-hospital cardiac arrest is considered as a standard care. However, optimal candidates, optimal dose, duration, timing of initiation and rate of rewarming is still unknown. The objective of this project is to improve the outcomes for patients after resuscitation from out-of-hospital cardiac arrest treated with therapeutic hypothermia established from the analysis of multicenter registry data.
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.
We aimed to investigate the efficiency of chemical oocyte activation using readymade Ca2+ ionophore on cases with previously cancelled cases due to fertilization arrest at pronuclear stage i.e: cleavage failure to find out if there is any improvement in embryonic developmental stages.
In-hospital pediatric cardiac arrest is an important public health problem affecting almost 6000 children a year in the United States. As many as 3% of patients admitted to a children's hospital require cardiopulmonary resuscitation (CPR). Only a minority of children survive, of which around 35% go on to have a poor neurological outcome. International consensus guidelines on science and treatment recommendations for the management of pediatric resuscitation have existed for decades and are revised periodically by the International Liaison Committee on Resuscitation (ILCOR) based on available evidence. This consensus is then used by national councils such as the American Heart Association (AHA) and the Heart and Stroke Foundation of Canada (HSFC) to make guidelines for care. These guidelines focus on a structured approach to resuscitation, which emphasizes the rapid implementation of key interventions such as starting chest compressions, administering epinephrine and defibrillation. The goal of this study is to improve outcomes after cardiac arrest in children by improving adherence to consensus guidelines. The investigators aim to achieve this by conducting a multi-center, prospective, factorial randomized study with participating sites from the International Network for Simulation-based Pediatric Innovation, Research and Education (INSPIRE). The specific aims of this study are to: 1. To evaluate the effectiveness of knowledge-based cognitive aids, namely the Pediatric Advanced Life Support (PALS) algorithm cards, in healthcare teams. 2. To evaluate the effectiveness of teamwork-based cognitive aids, namely the Cognitive Aids with Roles Defined (CARD) system, in healthcare teams. 3. To determine if there is a synergistic effect when adding the CARD system to the use of knowledge-based cognitive aids or indeed whether using both these tools together has unintended consequences and reduces the added value of each technique. 4. To identify whether additional simulation-based team training in the use of cognitive aids results in a significant improvement in performance over an e-learning module. The investigators hypothesize that (i) knowledge-based cognitive aids will significantly improve the performance of healthcare teams in providing PALS in a simulated setting, (ii) that teamwork-based cognitive aids (CARD) will significantly improve the performance of healthcare teams in providing PALS in a simulated setting, and that (iii) adding the CARD system to knowledge-based aids will have an added and synergistic effect, (iv) that the team performance in all study arms will improve after simulation based training, but that the groups with cognitive aids will continue to out-perform the groups without cognitive aids.
This is a prospective, observational study to investigate molecular mechanisms mediating the systemic inflammatory process, and changes to metabolism, and their impact on brain injury, survival, and functional outcomes after cardiac arrest. Investigators have shown that cardiac arrest induces changes in the numbers and properties of circulating immune cells, shifting the balance towards a pro-inflammatory phenotype and there is increased interest in the inflammatory pathways and the signaling mechanisms through which they are modulated. Participants will undergo blood sampling during 7 days following cardiac arrest, and analyses performed. Patient characteristics, clinical circumstances, and outcomes will be recorded and their associations with these inflammatory pathways characterized.
This study is designed as a multicenter, prospective, cohort clinical study. The out of hospital cardiac arrest (OHCA) patients presenting to the adult emergency departments of the participating hospitals will render the study population. The non-traumatic, non-intracranial event related OHCA patients in whom the return of spontaneous circulation (ROSC) is achieved will render the sampling group. The primary aim of this study is to evaluate the relationship of bedside ultrasound (USG) measurements of Optic Nerve Sheath Diameter (ONSD) following the ROSC after Cardiopulmonary resuscitation (CPR) for OHCA patients, with early (3rd day) neurological evaluation and 30 days survival rate, proposing that increased ONSD may be related to negative neurological outcomes. Considering a relationship is found, the secondary goals of the study are established as, identifying a cut-off value for ONSD related to negative neurological outcome and the optimal time to measure ONSD. The sampling size with a power of 95% is calculated to be 203 patients. The patients whose available next of kin has given consent will be admitted to the study.
The purpose of this study is to determine whether targeted temperature management at 36.0˚C(TTM-36) in patients who remain unconscious after resuscitation from in-hospital cardiac arrest(IHCA) will reduce death and disability compared with fever control. For this purpose, the current pilot study will be undertaken to establish the feasibility, safety, and surrogate outcomes of hypoxic-ischemic brain injury in 60 patients who remain unconscious after resuscitation from IHCA. Eligible patients will be randomly assigned in a 2:1 ratio to either TTM-36(n=40) or conventional treatment group(n=20). Randomization will be performed with stratification according to initial rhythm (shockable vs. non-shockable).
