Time to defibrillation is the most important predictor of survival in cardiac arrest. Traditional emergency medical system response is often to slow. The aim of this study is to investigate the feasibility of drone systems that delivers Automated External Defibrillators (AED) to the scene of suspected Out-of-Hospital Cardiac Arrests (OHCA). This study will test the feasibility of real-life flights with drones carrying automated external defibrillators (AEDs) to out-of-hospital cardiac arrest (OHCA) as a complement to standard care i.e EMS
Time-limited adaptive responses of thyroid function are common in the critically ill. About 70% of all patients treated on intensive care units develop a so-called non-thyroidal illness syndrome (NTIS) or TACITUS (thyroid allostasis in critical illness, tumours, uraemia and starvation), which is marked by low serum concentrations of the thyroid hormone T3 and other adaptive reactions of thyroid homeostasis. Occasionally, temporarily elevated concentrations of thyrotropin (TSH) and peripheral thyroid hormones are to be observed, especially after cardiopulmonary resuscitation (CPR). However, the available evidence is limited, although abnormal concentrations of thyroid hormones after CPR have occasionally been reported. Aim of the planned study is to investigate the thyrotropic (i.e. thyroid-controlling) partial function of the anterior pituitary lobe immediately after CPR. It is intended to evaluate statistical measures of TSH concentration and peripheral thyroid hormones in de-identified datasets (protocol A). Additionally, a prospective sub-study (protocol B) aims at a more precise description of pituitary and thyroid responses by means of serial investigations in routine serum samples, both immediately after CPR and during the course of ongoing treatment. This includes the evaluation of additional possible predictors, too. Primary endpoint of the study is changed TSH concentration immediately after CPR compared to the TSH value 24 hours later. Secondary endpoint is the relation between thyroid-controlling pituitary function and mortality. A high proportion of patients undergoing CPR will eventually receive iodinated radiocontrast media (e.g. for computed tomography or coronary angiography). This is one of the reasons why early identifying subjects at high risk for possible iodine-induced thyrotoxicosis is important. Increased oxygen consumption of the heart in hyperthyroidism is one of the reasons for high mortality in thyrotoxicosis. Therefore, accurate diagnosis of alterations in the hypothalamus-pituitary-thyroid (HPT) axis is of paramount importance.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the novel coronavirus disease 2019 (COVID-19) pandemic. Among COVID-19 complications, in-hospital cardiac arrest (IHCA) was reported with a very poor outcome in a retrospective single-center study (0,7% of 30 days survival with good neurological outcome among IHCA patients with a resuscitation attempt), related to its natural course and management. The incidence of unexpected in-ICU cardiac arrest (ICUCA) due to COVID-19 is still unknown. Additionally, outcome of COVID-19 patients admitted in ICU for an out-of-hospital cardiac arrest (OHCA) is also undescribed. The objective this study is : - to report the incidence of ICUCA among patients hospitalized in French ICU for COVID-19. - to report morbidity and mortality among COVID-19 patients admitted alive in ICU for an OHCA or an IHCA. The secondary objective is to assess outcome and identify risk factors of ICUCA occurrence among patients admitted for COVID-19.
Unexpected cardiac arrest is a frequent and devastating event with a high mortality and morbidity. Half of the patients who survive to ICU admission ultimately die because of hypoxic-ischemic encephalopathy. With CPR and advanced life support, blood and oxygen delivery to heart and brain is preserved until circulation is restored. During CPR, coronary perfusion pressure is a significant predictor of increased rates of return of spontaneous circulation (ROSC) and survival to hospital discharge, while cerebral perfusion pressure is crucial for good neurologic outcome. Existing efforts to reduce mortality and morbidity focus on rapid recognition of cardiac arrest, initiation of basic and advanced life support (ALS), and optimization of post-arrest care. Clamping the descending aorta during cardio-pulmonary resuscitation (CPR) should redistribute the blood flow towards brain and heart. Animal models of continuous balloon occlusion of the aorta in non-traumatic cardiac arrest have shown meaningful increases in coronary artery blood flow, coronary artery perfusion pressure and carotid blood flow, leading to improved rates of ROSC, 48h-survival and neurological function. In humans, occlusion of the aorta using a REBOA catheter in the management of non-compressible abdominal or pelvic hemorrhage has shown improvements in hemodynamic profiles and has proved to be feasible in both, clinical and preclinical settings for trauma patients in hemorrhagic shock. These promising data provide an opportunity to improve outcome after cardiac arrest in humans too. The investigators have developed a protocol for the reliable and safe placement of a REBOA-catheter during cardiac arrest in a clinical setting (see ClinicalTrials.gov Identifier: NCT03664557). Damage to heart and brain from lack of oxygen supply occurs during the first minutes following cardiac arrest. It is therefore crucial to apply any measure to improve efficacy of CPR early in the course of events and therapy. After proving feasibility in a clinical setting in the trial mentioned above, the next logical step and specific goal of this study is to transfer this protocol to the preclinical setting, and to investigate the effect of temporary endovascular occlusion of the descending aorta on the efficacy of CPR early in the course of treatment of out-of hospital cardiac arrest by means of an increase in blood pressure.
The current COVID-19 pandemic, this is especially since the transmission of SARS-CoV-2 is thought to occur mainly through respiratory droplets generated by coughing and sneezing, by direct contact with contaminated surfaces and because in a large number of patients COVID-19 disease may be asymptomatic. As recommended by the CDC medical personnel should be equipped with full personal protective equipment (PPE) for AGP in contact with suspected/confirmed COVID-19 patient. Therefore, it is reasonable to search for the most effective methods of intravascular access in those conditions.
The safety and efficacy of a laryngoscopy as a primary intubation tool in urgent endotracheal intubation of cardiac arrest patients with suspected/confirmed COVID-19 has not been well-described in the literature. This study will answer whether using a Vie Scope laryngoscope will impact on the efficacy and safety of intubation compared with a traditional direct laryngoscopy.
Recent evidence suggests ketamine may attenuate harmful cellular cascades taking place after brain injury that result in permanent damage. The investigators are interested in researching the application of this in the setting of cardiac arrest. Following cardiac arrest, the brain is deprived oxygen for a period of time, leading to the imitation of these harmful cellular processes. The investigators hypothesize that patients who receive ketamine as part of their standard sedation procedures during cardiac arrest treatment have better neurological functioning compared to those who do not.
The risk of a severe medical event during long-duration spaceflight is significant and can endanger both the whole mission and crew. There is a certain risk for a cardiac arrest in space requiring cardiopulmonary resuscitation (CPR). So far, 5 known techniques to perform CPR in microgravity have been reported. The aim of the present study was to describe and gather data for two new CPR techniques useful in microgravity.
Rational: Out of hospital cardiac arrest is a devastating event with a high mortality. Survival rates have increased over the last years, with the availability of AED's and public BLS. Previous studies have shown that deranged physiology after return of spontaneous circulation (ROSC) is associated with a worse neurological outcome. Good quality post-arrest care is therefore of utmost importance. Objective: To determine how often prehospital crews (with their given skills set) encounter problems meeting optimal post-ROSC targets in patients suffering from OHCA, and to investigate if this can be predicted based on patient-, provider- or treatment factors. Study design: Prospective cohort study of all patients attended by the EMS services with an OHCA who regain ROSC and are transported to a single university hospital, in order to identify those patients with a ROSC after a non-traumatic OHCA who had deranged physiology and/or complications from OHCA EMS personnel was unable to prevent/deal with in the prehospital environment. Study population: Patients, >18 years, transported by the EMS services to the ED of the University Hospital Groningen (UMCG) with a ROSC after OHCA in a 1 year period Main study parameters/endpoints: Primary endpoint of our study is the percentage of OHCA patients with a prehospital ROSC who arrive in hospital with either a deranged physiology or with complications from OHCA EMS personnel was unable to deal with.
