Active clinical trials for "Emergencies"

This study will assess the feasibility of performing pre-hospital resuscitative endovascular balloon occlusion of the aorta (REBOA) as an adjunct to conventional Advanced Life Support (ALS) in patients suffering from non-traumatic out of hospital cardiac arrest (OHCA). As well as providing valuable insights into the technical feasibility of performing this procedure as part of a resuscitation attempt, the study will also document the beneficial physiological effects of REBOA in this group of patients.

The goal of this observational study is to determine the utility of desmosine, D-dimer and aggrecan as early diagnostic biomarkers in aortic dissection. The main questions it aims to answer are: To investigate the plasma levels of selected biomarkers in ED patients with confirmed aortic dissection To study the diagnostic performance of plasma levels of selected biomarkers for aortic dissection To study the association between plasma levels of selected biomarkers and clinical outcomes

Mivacurium can be considered as an optimal choice for muscle relaxation in short duration surgeries, as butyrylcholinesterase can rapidly and reliably degrade this benzylisoquinoline muscle relaxant in vivo. However the histamine release related to a rapid high-dose injection, unsatisfactory intubation conditions and unexpected delay in recovery in patients may be encountered with butyrylcholinesterase deficiency

The goal of this pilot randomized control trial is to assess the feasibility of our patient recruitment and data collection strategy ahead of a full scale RCT investigating the efficacy of oral v. parenteral medications in the management of acute migraine headaches in the emergency department. Patients will be randomly assigned to receive either (A) standard medical therapy for the treatment of acute migraine headache (metoclopramide and ketorolac IV) and oral placebo or (B) oral metoclopramide and ibuprofen with normal saline IV. Primary outcome measures are recruitment rate and improvement in pain score at 60 minutes from medication administration.

Acute exacerbation of asthma represents an acute or sub-acute worsening in symptoms and lung function in patients with asthma. It is characterized by a progressive increase in symptoms of shortness of breath, cough, wheezing, or chest tightness. It is a common diagnosis in patients admitted in an Emergency Department for dyspnoea. Near 10 to 15% of respiratory symptoms in an ED are related to acute exacerbation of asthma. Treatment of acute exacerbation of asthma associates nebulized beta-2 agonist adrenergic with or without ipratropium bromide, oral corticosteroids and controlled oxygen therapy to maintain SpO2 between 93 and 95%. Treatment in the ED did not vary during last years, including for patients with a lack of efficacy after first line treatment, and exacerbation are always associated with a hospitalisation in 40% of adult patients and with mortality in 1% of hospitalized patients. Vibrating mesh nebulizers are devices using vibration to push drug through the mesh, resulting in the drug nebulization. Vibrating mesh nebulizers have been associated with better pulmonary drug delivery than jet-nebulizers, provide faster improvement in peak expiratory flow and have been associated in retrospective studies with patient prognosis, particularly in terms of throughput time and need for hospitalisation. However, no studies have prospectively compared nebulisation with a vibrating membrane device with standard nebulisation in patients with asthma exacerbation on clinically relevant criteria. Nebulisation with a vibrating membrane device may potentiate the clinical efficacy of short-acting bronchodilators, result in faster and more effective clinical improvement, and be associated with improved short- and medium-term patient outcomes. High-flow nasal cannula heated, and humidified oxygen (HNFO) is a ventilatory support which is commonly used for the management of acute respiratory failure for acute respiratory failure in intensive care units and in emergency departments. HFNO delivers high fraction of inspired oxygen (FiO2), generates a low level of positive pressure and provides washout of dead space in the upper airways, thereby improving mechanical pulmonary properties and unloading inspiratory muscles during ARF. Consequently, HFNO is associated with a decrease in the work of breathing. During asthma exacerbation, HFNO was associated with an improvement in the dyspnea level and in the respiratory rate compared with conventional oxygen therapy. However, HFNO has never been assessed in association with nebulized beta-2 adrenergic agonist. To resume, beta-2 adrenergic agonist nebulization with a vibrating mesh nebulizer seems effective, especially compared to standard jet nebulization. In addition, HFNO is a technique that appears to be suitable for the pathophysiological conditions of chronic reversible respiratory failure, and can be used during exacerbations of asthmatic disease. The high flow rate of gas makes it possible to control the FiO2 in order to avoid hyperoxia, to generate a PEEP effect, to reduce the patient's work of breathing and the respiratory resistance, and to avoid the re-inhalation of CO2 by a dead space wash-out. In the EOLE study, the investigators propose to compare three therapeutic management strategies. One standard strategy (nebulisation with a jet-nebulizer), and two experimental strategies (nebulisation with a vibrating mesh device, and nebulisation with a vibrating mesh device in association with HFNO). The investigators hypothesise that bronchodilator nebulization with a vibrating mesh nebulizer is more effective than jet-nebulizers for the management of patients admitted for asthma exacerbation and non-responders or with lack to efficacy to initial treatment. Furthermore, the investigators also hypothesise that the addition of the physiological effects of HFNO may enhance the efficacy of the treatment. The therapeutic effects of nebulisation with a vibrating membrane device alone or with the addition of the physiological effects of HFNO could constitute a new approach to the management of asthma patients, particularly in patients who are insufficiently responsive or non-respondent to initial treatment.

BACKGROUND: At Emergency Medical Dispatch (EMD) centers, Resource Constrained Situations (RCS) where there are more callers requiring an ambulance than there are available ambulances are common. At the EMD centers in Uppsala and Västmanland, patients experiencing these situations are typically assigned a low-priority response, are often elderly, and have non-specific symptoms. Machine learning techniques offer a promising but largely untested approach to assessing risks among these patients. OBJECTIVES: To establish whether the provision of machine learning-based risk scores improves the ability of dispatchers to identify patients at high risk for deterioration in RCS. DESIGN: Multi-centre, parallel-grouped, randomized, analyst-blinded trial. POPULATION: Adult patients contacting the national emergency line (112), assessed by a dispatch nurse in Uppsala or Västmanland as requiring a low-priority ambulance response, and experiencing an RCS. OUTCOMES: Primary: 1. Proportion of RCS where the first available ambulance was dispatched to the patient with the highest National Early Warning Score (NEWS) score Secondary: Difference in composite risk score consisting of ambulance interventions, emergent transport, hospital admission, intensive care, and mortality between patients receiving immediate vs. delayed ambulance response during RCS. Difference in NEWS between patients receiving immediate vs. delayed ambulance response during RCS. INTERVENTION: A machine learning model will estimate the risk associated with each patient involved in the RCS, and propose a patient to receive the available ambulance. In the intervention arm only, the assessment will be displayed in a user interface integrated into the dispatching system. TRIAL SIZE: 1500 RCS each consisting of multiple patients randomized 1:1 to control and intervention arms

Syncope, or transient loss of consciousness, is a common reason for visit to the Emergency Department and often leads to extensive testing and hospitalization. Using objective risk scores to determine which patients with syncope will actually benefit from these interventions, and which can be safely discharged home with minimal testing, is critical to providing sensible medical care. This study will evaluate the validity of two syncope risk-stratification tools and investigate their impact on healthcare utilization and patient safety, thus improving the quality of care for the 1-2 million patients who experience syncope every year in the United States

Although laparoscopic repair (LR) of perforated peptic ulcers (PPUs) has long been accepted, clinical evidence comparing LR versus open repair (OR) remains lacking. The aim of this study is to evaluate the feasibility, safety and outcome of laparoscopic gastric repair and compare it with the outcome open repair by relying on a propensity score matching statistical technique

The conventional standard-dose scanner leads to a significantly greater X-ray exposure than the standard X-ray. Recently, technological innovations like the ULD ("Ultra Low Dose") scanner have been developed to reduce the dose of X-rays delivered to the patient. The general purpose of this study is to validate the ULD scanner in case of emergency trauma of the dorsolumbar spine, pelvis and / or extremities.

The aim of the study is to investigate whether a voice activated cognitive aid can improve performance in a simulated emergency front-of-neck access scenario. This skill is ideally practiced on an annual basis by anaesthetists in training, with a variety of usually low-fidelity simulation used. The addition of the Alexa cognitive aid is a novel step with the aim of improving adherence to the recommended steps required to successfully complete the procedure. One arm of this study will be introduced to the Alexa checklist in advance of performing the procedure prior to crossover, whereas the second arm will not (subject to standard anaesthetic training).
