The Value of Rapid Shallow Breathing Indeks in Predicting Non-invasive Mechanical
Acute Respiratory FailureThere are some criteria such as the most frequently used parameters to predict the failure of non-invasive mechanical ventilation, the APACHE 2 score, the presence of pneumonia and ARDS in the etiology, and no improvement in one hour of treatment. However, APECHE 2 score, which is the broadest of these criteria and includes others, is a complex scoring in which a large number of parameters are evaluated together, dependent on laboratory results and still leaves the final decision to the physician with a complete evaluation. In addition, the APACHE 2 score is a more commonly used method for intensive care patients rather than emergency patients who need a quick decision. Therefore, there is a need for a fast and practical method that can predict NIMV failure and determine early intubation decision in the management of patients admitted to the emergency department with acute dyspnea. Rapid Shallow Breathing Index (RSBI) is a parameter calculated by dividing the respiratory rate by the tidal volume and is used to predict whether patients who are intubated in intensive care unit can be extubated successfully. The aim of this study is to evaluate the success of RSBI in predicting intubation and mortality in patients presented to the emergency department with acute respiratory failure and had NIMV indication.
Booster Dose of COVID-19 Vaccine for Kidney Transplant Recipients Without Adequate Humoral Response...
COVID-19 Acute Respiratory Distress SyndromeImmunosuppressionIntroduction: Inadequate antibody response to mRNA SARS-CoV-2 vaccination has been described among kidney transplant recipients. Immunosuppression level and specifically, use of antimetabolite in the maintenance immunosuppressive regimen, are associated with inadequate response. In light of the severe consequences of COVID-19 in solid organ transplant recipients, we believe it is justified to examine new vaccination strategies in these patients. Methods and analysis: BECAME is a single center, open label, investigator-initiated randomised controlled, superiority trial, aiming to compare immunosuppression reduction combined with a third BNT162b2 vaccine dose versus third dose alone. The primary outcome will be seropositivity rate against SARS-CoV-2. A sample size of 154 patients was calculated for the seropositivity endpoint assuming 25% seropositivity in the control group and 50% in the intervention group. A sample of participant per arm will be also teste for T-cell response. We also plan to perform a prospective observational study, evaluating seropositivity among ~350 kidney transplant recipients consenting to receive a third vaccine dose, who are not eligible for the randomised controlled trial. Ethics and dissemination: The trial is approved by local ethics committee of Rabin medical center (RMC-0192- 21). Results of this trial will be published; trial data will be available. Protocol amendments will be submitted to the local ethics committee.
High-flow Oxygen Therapy vs Non-invasive Ventilation: Comparison of Alveolar Recruitment in Acute...
Acute Respiratory Failure With HypoxiaThis physiological study showed an increase in regional ventilation with NIV but no difference in alveolar recruitment as compared to HFNC in patients with hypoxemic ARF. Although NIV provided better oxygenation than HFNC, the effect on lung volumes could explain the potentially deleterious effect of NIV in hypoxemic ARF, reinforcing the recently developed concept of patient self-inflicted lung injury.
Effects of Bolus Surfactant Therapy on Peripheral Perfusion Index and Tissue Carbon Monoxide
Respiratory Distress SyndromeExogenous bolus surfactant administration may affect hemodynamic parameters and peripheral perfusion. Surfactant therapy is commonly used for respiratory distress syndrome in premature infants, which is also associated with inflammation. There are different types and doses of surfactant preparations available. With the help of new generation monitors, changes in peripheral perfusion and transcutaneous CO, a marker of inflammation, may be demonstrated.
Predictive Values of Plasma Soluble RAGE Levels and RAGE Polymorphisms for the Onset of Acute Respiratory...
Intensive Care UnitPopulation at High Risk for ARDS DevelopmentCurrent clinical prediction scores for acute respiratory distress syndrome (ARDS) have limited positive predictive value. No studies have evaluated predictive kinetics of plasma biomarkers and receptor for advanced glycation end products (RAGE) polymorphisms in a broad population of critically ill patients or as an adjunct to clinical prediction scores. The main objective of the investigators study is to evaluate the predictive values of plasma soluble RAGE levels for the onset of ARDS in a high risk population of patients admitted to the intensive care unit (ICU). One of the investigators goals is to improve early identification of patients at risk for ARDS in order to better implement preventive stategies prior to ARDS development. The primary outcome is the occurrence of ARDS during the first week after admission to the ICU.
Lung Ultrasound to Diagnose Transient Tachypnea of the Newborn (TTN) Versus Respiratory Distress...
Transient Tachypnea of the NewbornTTN2 moreThe investigators hypothesize that ultrasonography of the newborn lung can be used as an effective diagnostic tool in neonates ≥ 28 weeks gestation with early symptoms of respiratory distress.
Changes in Refractory Acute Respiratory Distress Syndrome (ARDS) Patients Under High Frequency Oscillation-ventilation...
Respiratory Distress SyndromeAdultThe study is intended to evaluate the hemodynamic and the indexed extrapulmonary lung water (ELWI) changes in patients treated by high frequency oscillation-ventilation (HFO-V) for refractory acute respiratory distress syndrome (ARDS). HFO-V may be used as rescue treatment in refractory ARDS but its hemodynamic impact is discussed. Moreover, as Extra Vascular Lung Water (a transpulmonary thermodilution parameter) was proven to be an independent mortality factor in ICU-patients, the investigators decided to monitor it in all ARDS patients who ended up needing HFO-V, from HFO-V plugging under 72 hours of this type of ventilation. All ARDS patients underwent high Positive End Expiratory Pressure (PEEP) with "protective ventilation" and those who remained below a PaO2/FiO2 ratio of 120 after 24h will be considered as "refractory ARDS patients" and, therefore eligible. They will be monitored by the transpulmonary thermodilution PiCCO technique (Pulsion Medical System. Munich, Germany) and placed under HFO-V. Both transpulmonary thermodilution measurements (ELWI , Cardiac Output, Global End-diastolic Volume) and standard transthoracic echocardiographic measurements (Ejection Fraction, End-diastolic Right and Left Ventricular Area, preload indexes) were be performed from HFO-V plugging to Day 3. The investigators suggest that ELWI will be correlated to HFO-V responsiveness and that cardiac output will not change at the HFO-V plugging, regardless of preload indexes variation. Inclusion will be proceeded over a 2 year period and, according to the population, the investigators expect about 50 eligible patients.
Prevention of Chronic Lung Disease (CLD) in Preterm Infants
Respiratory Distress SyndromeChronic Lung Disease of PrematurityPulmonary inflammation plays an important role in the early development of CLD. Postnatal glucocorticoids have been shown effective in the prevention or treatment of CLD with various success. However, systemic glucocorticoid therapy often associated with various short term and long term complications. Therefore, modification of the therapeutic regimen is needed. Inhaled steroid, including inhaled budesonide,have been tried but the results are essentially unsuccessful, most likely due to small airways that the inhaled steroid reaching to the peripheral lungs are limited and unpredictable. Direct instillation of budesonide into the airway has also shown to be ineffective, possibly due to poor distribution of steroid in the lungs. The investigators hypothesize that intratracheal instillation of budesonide, a strong tropical steroid, using surfactant as vehicle would facilitate the delivery of budesonide to the lung periphery and would inhibit lung inflammation and improve the pulmonary outcome. The result of our pilot study (Pediatrics, 2008) indicated this high possibility.
Continuous Monitoring of Lung Ventilation
Respiratory Distress SyndromeNewborn4 moreBackground: Patients that suffer from respiratory failure and need mechanical ventilation are at risk of further deterioration due to complications induced by progression of lung disease or the mechanical ventilation. The complications usually develop in a progressive manner, but are currently detected relatively late, when there is already severe and life threatening deterioration in patient oxygenation and sometimes irreversible damages. Objective:To measure chest wall dynamics, derived from sensors placed on the chest and abdomen. Methods: The system comprises of patches attached to the chest wall and upper abdomen that include mechanical sensors that measure the mechanics of lung inflation and deflation.
Influence of Acute Respiratory Distress Syndrome (ARDS) and Severe Sepsis on sRAGE Levels in ICU...
Acute Lung InjuryAcute Respiratory Distress Syndrome3 moresRAGE, the soluble form of the receptor for advanced glycation end products, is a novel marker of alveolar epithelial type I cell injury, but is also involved in acute systemic inflammation. The purpose of this observational prospective study is to determine whether sRAGE could be used in an ICU setting as a potential diagnostic and prognostic marker during ALI/ARDS, regardless of associated severe sepsis or septic shock.
