Active clinical trials for "Acute Lung Injury"

The purpose of this study is to assess the left diastolic function at different levels of in patients affected by the acute respiratory distress syndrome (ARDS)

Mannose-binding lectin (MBL) plays an important role in the innate immune response. In addition to activating the complement, MBL can induce cytokine production and contribute to a deleterious inflammatory response with severe A(H1N1)pdm09 virus infection. The aim was to determine if serum MBL levels correlate with the risk of mortality in intensive care units (ICU) patients with A(H1N1)pdm09 infection. Prospective observational study was performed in ICU patients with acute respiratory distress syndrome due to influenza A(H1N1)pdm09 virus. Demographic characteristics and severity indices were recorded at ICU admission. MBL was assayed from blood drawn at influenza diagnosis within 24-48 h following the ICU admission. Outcomes were compared according to MBL levels.

Introduction: Electrical Impedance Tomography (TIE) consists of an equipment that enables the visualization / quantification in real time of the regional distribution of ventilation and pulmonary perfusion, as well as of ventilatory mechanics. Used on the edge of the bed, it is easy to move, non-invasive, allowing a momentary or continuous assessment, guiding the conduct in a safe and precise way through the electrical impedance technology. It is important to note that, in addition to ensuring the efficacy of the patient's behavior, the TIE supports the most diverse types of studies to be performed. These include those based on the effectiveness of the use of the method in the most diverse pulmonary dysfunctions, in the adjustment of the mechanical ventilation and in the average time of hospitalization. Objective: To evaluate the pulmonary function of patients in invasive mechanical ventilation through SIT. Method: This research was carried out in compliance with the National Health Council's Guidelines for Research Involving Human Beings (466/12). The study was a prospective longitudinal clinical-experimental type in which all patients (occasional sampling) used mechanical ventilation and were hospitalized in the Adult Intensive Care Unit (ICU) of the Santa Casa de Misericórdia Foundation of Pará, and they developed sepsis with pulmonary repercussions; (DEHG) / HELLP Syndrome and Adult Respiratory Distress Syndrome (ARDS) and who met the inclusion criteria were evaluated and monitored with TIE to perform ventilatory therapy according to the research objectives. The research was carried out in the city of Belém, in the state of Pará, in the adult ICU of the FSCMP. As inclusion criterion, the patient should be in the FSCMP adult Intensive Care Unit (ICU), under mechanical invasive ventilation, previously authorized by the family through the Informed Consent Form to participate in the study.

The authors hypothesized that inhaled sedation, either with isoflurane or sevoflurane, might be associated with improved clinical outcomes in patients with COVID-19-related ARDS, compared to intravenous sedation. The authors therefore designed the "Inhaled Sedation for COVID-19-related ARDS" (ISCA) non-interventional, observational, multicenter study of data collected from the patients' medical records in order to: assess the efficacy of inhaled sedation in improving a composite outcome of mortality and time off the ventilator at 28 days in patients with COVID-19-related ARDS, in comparison to a control group receiving intravenous sedation (primary objective), investigate the effects of inhaled sedation, compared to intravenous sedation, on lung function as assessed by gas exchange and physiologic measures in patients with COVID-19-related ARDS (secondary objective), report sedation practice patterns in critically ill patients during the COVID-19 pandemics (secondary objective).

Coronavirus disease 2019 (abbreviated "COVID- 19") is a pandemic respiratory disease that is caused by a novel coronavirus and was first detected in December 2019 in Wuhan, China. The disease is highly infectious, and its main clinical symptoms include fever, dry cough, fatigue, myalgia, and dyspnoea.1 In China, 18.5% of the patients with COVID-19 developed to the severe stage, which is characterized by acute respiratory distress syndrome, septic shock, difficult-to-tackle metabolic acidosis, and bleeding and coagulation dysfunction. After China, COVID-19 spread across the world and many governments implemented unprecedented measures like suspension of public transportation, the closing of public spaces, close management of communities, and isolation and care for infected people and suspected cases. The Malaysian government had enforced Movement Control Order (MCO) from 18th March to 4th May 2020 and henceforth Conditional Movement Control Order (CMCO) until 9th June 2020. The battle against COVID-19 is still continuing in Malaysia and all over the world. Due to the CMO and CMCO in the country, public and private universities have activated the e-learning mode for classes and as the government ordered, universities are closed and no face-to-face activities allowed. This has forced students of all disciplines including dentistry to stay at home which are wide-spread across Malaysia and shift to e- learning mode. To guarantee the final success for fight against COVID-19, regardless of their education status, students' adherence to these control measures are essential, which is largely affected by their knowledge, attitudes, and practices (KAP) towards COVID-19 in accordance with KAP theory. Once the restrictions are eased students have to come back and resume their clinical work in the campus. Hence, in this study we assessed the Knowledge, Attitude, and Practice (KAP) towards COVID-19 and the students preference for online learning.

The latest epidemiological data published from Chine reports that up to 30% of hospital-admitted patients required admission to intensive care units (ICU). The cause for ICU admission for most patients is very severe respiratory failure; 80% of the patients present with severe acute respiratory distress syndrome (SARS) that requires protective mechanical ventilation. Five percent of patients with SARS require extracorporeal circulation (ECMO) techniques. Global mortality data has been thus far reported in different individual publications from China. Without accounting for those patients still admitted to hospital, bona fide information (from a hospital in Wuhan) received by the PI of this project estimates that mortality of hospitalized patients is more than 10%. Evidently, mortality is concentrated in patients admitted to the ICU and those patients who require mechanical ventilation and present with SARS. As data in China was globally reported, risk factors and prognosis of patients with and without SARS who require mechanical ventilation are not definitively known. The efficacy of different treatments administered empirically or based on small, observation studies is also not known. With many still admitted at the time of publication, a recent study in JAMA about 1500 patients admitted to the ICU in the region of Lombardy (Italy) reported a crude mortality rate of 25%. The data published until the current date is merely observational, prospective or retrospective. Data has not been recorded by analysis performed with artificial intelligence (machine learning) in order to report much more personalized results. Furthermore, as it concerns patients admitted to the ICU who survive, respiratory and cardiovascular consequences, as well as quality of living are completely unknown. The study further aims to investigate quality of life and different respiratory and cardiovascular outcomes at 6 months, as well as crude mortality within 1 year after discharge of patients with COVID-19 who survive following ICU admission. Lastly, with the objective to help personalize treatment in accordance with altered biological pathways in each patient, two types of studies will be performed: 1) epigenetics and 2) predictive enrichment of biomarkers in plasma. Hypothesis A significant percentage of patients (20%) admitted to the hospital with COVID-19 infection is expected to require ICU admission, and need mechanical ventilation (80%) and, in a minor percentage (5%), ECMO. Patients who survive an acute episode during ICU hospitalization will have a yearly accumulated mortality of 40%. Those who then survive will have respiratory consequences, cardiovascular complications and poor quality of life (6 months).

By using Mechanical Power and Driving Pressure instead of Pmean we calculate new oxygen saturation indices like Driving Pressure Oxygen Index (OIDP), Dynamic Power Oxygen Index (OIMPdyn), Total Power Oxygen Index (OIMPtot), Driving Pressure Saturation Index (OSIDP), Dynamic Power Saturation Index (OSIMPdyn) ve Power Saturation Index (OSIMPtot). New oxygenation and saturation indices are able to predict ICU mortality better than the conventional indexes and rates.

Excessive respiratory effort may cause self-inflicted lung injury (SILI) and inspiratory muscle injuries , stimulate desynchronization between the patient and ventilator , and worsen the perfusion of extrapulmonary organs . Appropriate respiratory drive and effort should be maintained during the treatment of patients with respiratory failure . In contrast, respiratory drive and effort are commonly increased in patients with COVID-19 pneumonia , and this phenomenon may persist in critically ill patients with COVID-19, even after receiving venovenous ECMO (vv-ECMO) support, owing to low pulmonary compliance and a high systemic inflammatory state . To reduce respiratory effort and drive, ICU physicians often administer high doses of sedative drugs, analgesics, and muscle relaxants. The prolonged use of high doses of these drugs can cause loss of the spontaneous cough reflex, which in turn impairs sputum drainage and eventually worsens pulmonary consolidation and lung infections. As the partial pressure of carbon dioxide in arterial blood (PaCO2) could affect the respiratory drive from the respiratory center (1), it has been shown that altering different levels of extracorporeal carbon dioxide removal in patients undergoing ECMO recovering from acute respiratory distress syndrome (ARDS) could alter respiratory drive. We hope to find a more appropriate target for maintaining PaCO2 to control respiratory effort in patients with COVID-19 undergoing ECMO.

The purpose of this international, multicenter service review is to describe and compare ventilation management in patients at risk of acute respiratory distress syndrome (ARDS) versus patients not at risk and patients with established ARDS, and to ascertain whether certain ventilator settings and ventilation parameters are associated with pulmonary complications or development of ARDS after start of ventilation in patients in intensive care units (ICUs) in Asian countries. Participating centers will include adult patients undergoing mechanical ventilation in the ICU during a 28-day period. Patients' data will be collected during the first 7 days in the ICU, or until ICU discharge. Follow up is until ICU discharge. The primary outcome includes two main ventilator settings, i.e., tidal volume and the level of positive end-expiratory pressure. Secondary endpoints are development of ARDS in patients without ARDS at the onset of mechanical ventilation, worsening of ARDS in patients with ARDS at the onset of mechanical ventilation, pulmonary infection, other pulmonary complications, need for tracheostomy, duration of ventilation, length of ICU stay and ICU mortality.

The results of this study will help to define the capability and reliability of PulmoVista 500 to detect changes in both global and regional ventilation.
