Filter by:The purpose of this study is to assess if, compared with standard paper-based systems, an automated Early Warning System (EWS) resident in a spot check patient monitor, can help to identify deteriorating patients.
In this mono-center prospective study, the impact of changes in the sphingolipid metabolism in patients with pulmonary edema will be investigated.
To evaluate the additive value of tadalafil given together with Diamox (acetazolamide) in preventing acute mountain sickness in travelers to high altitude areas.
Peri-operative fluid therapy is a controversial area with few randomized trials to guide practice. Fluid management has a significant influence on outcome following surgery. Yet practically, fluid prescription practice during this period is sub-optimal, resulting in avoidable iatrogenic complications. Several studies have assessed the effect of a 'liberal' vs. a 'restrictive' perioperative fluid regimen on post-operative outcome. However, most of these studies have focused primarily on intra-operative fluid management, whereas postoperative strategies have been less well defined, even though the immediate postoperative period is of critical importance to the patient's recovery. Moreover, whereas intra-operative fluid administration is monitored by the anesthesiologist, postoperatively it is less supervised and may result in excess or lack of intravenous (IV) fluids. Therefore, fluid management audit at the post-anesthesia care unit (PACU) is of paramount importance for patient healthcare. The objective of this study is to follow and report the current practice of fluid administration in the PACU of Tel Aviv Sourasky Medical Center, for an extended period of time as a first step towards establishing evidence-based guidelines for postoperative fluid management.
The aim of this study is to compare two methods of delivery of noninvasive mechanical ventilation (NIV). Since patient compliance and mechanical characteristics of the delivery devices are two fundamental variables in the success of NIV during acute respiratory failure, our hypothesis is that an improved patient-ventilator interface may improve the efficacy of therapy.
Currently Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-related mortality in the United States, and one of major post-transfusion complications. TRALI is defined as new ALI occurring within 6 hours from the onset of transfusion. It is manifested by acute dyspnea, hypoxemia and bilateral infiltrates in chest radiograph. TRALI may be caused by any blood product and is not dose-dependent. Associated risk factors include prolonged storage of blood products and underlying conditions such as severe IHD hematologic malignancies or active infections. Since TRALI has only recently been defined as a clinical entity, and its prevalence has been largely underestimated - the epidemiology of TRALI is not well established. Therefore the objective of this work is to study the incidence of TRALI in a patient population that receive blood products frequently, namely orthopedic-oncologic.
Cardiogenic pulmonary edema (CPE) is a common medical emergency and noninvasive ventilation (NIV) in addition to conventional medical treatment might be beneficial for patients with CPE.
Acute cardiogenic pulmonary edema (ACPE), one of the most severe forms of acute heart failure, represents 5% of hospital admissions. One of the most frequent phenomena encountered during ACPE is hypertensive crisis (hypertensive ACPE) but the mechanisms and causes of hypertensive ACPE are insufficiently understood. Few studies have evaluated the cardiac function during hypertensive ACPE, and these studies used only conventional echocardiography methods. New methods of evaluation of cardiac function in hypertensive ACPE (such as Tissue Doppler imaging) have not been used. The objectives of this study are to evaluate presence and role of the following potential mechanisms of hypertensive ACPE: 1. acute myocardial dysfunction (systolic and diastolic); 2. silent transient myocardial ischemia; 3. acute mechanical left ventricular dyssynchrony; 4. dynamic mitral regurgitation; 5. inter-ventricular interaction. Conventional and Tissue Doppler echocardiography will be used to assess cardiac function.
Immersion pulmonary edema (IPE) is a condition in which fluid fills the lungs during diving or swimming, particularly in cold water. Some individuals appear to be predisposed to developing IPE. DNA samples will be collected and stored, in order to compare the genetic profiles of individuals who have experienced IPE with those who have not. In a few individuals who have experienced IPE, we plan to measure the effects of cold water immersion on the blood pressure, cardiac output and the pressures in the pulmonary artery. These will be compared with similar measurements already obtained from normal individuals.
Non-invasive ventilation (NIV) has become now a widely used treatment modality in ICU and emergency services to deal with respiratory failure.1 NIV has the potential to improve ventilatory assistance while avoiding endotracheal intubation and its complications. Since the first publications of Meduri2 and Brochard3 the number of studies on the NIV has been growing and developing and this technique becomes one of the major progress in the field of respiratory assistance. Decompensation of chronic obstructive pulmonary disease (COPD) is certainly the least questionable indication of the NIV. However, indication of the NIV is inexorably spreading to other types of acute respiratory insufficiency, including acute cardiogenic pulmonary edema (CPE).4 Continuous positive airway pressure (CPAP) is the most currently used non-invasive ventilation usually performed without the use of a ventilator. NIV using pressure support (NIPSV) combined pressure support (inspiratory aid) and positive expiratory pressure as in CPAP. Based on physiological ground, NIPSV would be more performant than CPAP to improve ventilatory parameters and reduce the work breathing in APE. However, this issue is not settled yet. Number of meta-analysis over the last 2 years were devoted to the comparison of CPAP and NISPV,5 so that the scientific evidence is still far from established. In addition, it is not sur that patients enrolled in these studies are representative of all patients with APE. The fact that they were included solely on the basis of clinical criteria, the risk of overlap with other diagnoses is not negligible. Thus the use of markers of heart failure as the BNP (brain natriuretic peptide) would be very useful. On the other hand, the possible deleterious effect of NIPSV on myocardial perfusion is a problem that has not been definitively resolved. Objectives of the study: 1. Compare the efficacy and safety of the NIPSV with those of CPAP in patients presenting to the emergency department with CPE. 2. Compare the two procedures in subgroups of patients with hypercapnia and high BNP concentration.
