Active clinical trials for "Respiratory Distress Syndrome"

The corner stone of the treatment of ARDS is mechanical ventilation with high levels of positive end-expiratory pressure, also called PEEP. A high level of PEEP is recommended and frequently used. But PEEP can lower cardiac output and contribute to circulatory failure during mechanical ventilation. Nevertheless, in theory, the PEEP-induced pulmonary vascular resistance (PVR) increase could depend on the level of alveolar recruitment, but it has never been proven. Thus, the aim of this study is to determine the relation between the high-PEEP induced PVR and the alveolar recruitment or overdistension.

We aims to investigate the effects of prone positioning and nitric oxide inhalation in adult patients who is diagnosed with COVID-19 associated acute respiratory distress syndrome by electrical impedance tomography.

The goal of this observational clinical trial is to learn about the role white blood cells (macrophages) play in lung inflammation in people with Acute Respiratory Distress Syndrome (ARDS). The main questions it aims to answer are: How does the immune system respond to different kinds of lung injury and inflammation and how do those processes differ from each other? What roles do the cells that live in the lungs (macrophages) play in turning off inflammation? How does their role differ from other cells that are called to the lung to help repair injury (recruited macrophages)? Will more frequent testing of lung cell samples help reduce the time it takes to start treatment for ventilator-associated pneumonia (VAP) and therefore reduce the rates of initial therapy failure? Participants will be in the intensive care unit (ICU) on a mechanical ventilator (machine that helps you breathe) because they have ARDS or are on a mechanical ventilator for some other reason (control group). The following will happen: You will be given 100% oxygen through the breathing machine (mechanical ventilator) for 3-5 minutes. This is called pre-oxygenation. A lung specialist (pulmonologist), a member of Dr. Janssen's research team, or respiratory therapist will place small amount of saline into the lung using a long catheter going through the breathing tube. The fluid will be removed with suction and will be sent to the laboratory for testing. This will be repeated two more times over the course of 10 days, or less if you are taken off of the ventilator. The procedure will be performed no more than three times. Two nasal brushings will be taken from your nose. Approximately 3 tablespoons of blood will be removed by putting a needle into your vein. This is the standard method used to obtain blood for tests. A total of 9 tablespoons will be taken for research purposes over the course of this study Data including your age, sex, severity of illness, and other medical conditions will be recorded to determine how these can affect the white blood cells. If bacteria are isolated from the fluid in your lung, your physician may choose to place you on antibiotics to treat an infection. A follow-up phone call may be made by a member of the research team after discharge from the hospital. At this time, you may be invited to participate in the Post-ICU clinic at National Jewish Health.

Acute Respiratory Distress Syndrome (ARDS) is a highly lethal disease with limited treatment options. In recent years, prone position ventilation has been shown to improve the mortality rate and lung injury of ARDS patients by promoting lung recruitment, improving ventilation/perfusion (V/Q) ratio, enhancing respiratory system compliance, promoting sputum drainage, and effectively avoiding overinflation of the dorsal lung. Electrical Impedance Tomography (EIT) technology has been used to evaluate the effect of prone position ventilation on lung V/Q matching, and some studies have confirmed that prone position ventilation can improve lung V/Q matching and oxygenation index. However, previous studies were mostly case reports or small-sample physiological studies that lacked dynamic changes in lung V/Q matching during repeated prone position ventilation. Therefore, this study hypothesizes that prone position ventilation can increase lung V/Q matching in ARDS patients, and its improvement is correlated with changes in oxygenation index, invasive ventilation time, and patient prognosis. Repeated prone position ventilation can maintain lung V/Q matching at a higher level, no longer affected by changes in body position, which can accelerate pulmonary function recovery and improve the prognosis of ARDS patients.

To evaluate the safety, tolerability, PK, PD, and clinical activity of Itolizumab in subjects with acute respiratory distress syndrome (ARDS) caused by Infectious Pneumonia.

The purpose of this study is to identify the safest dose of recombinant surfactant protein D (drug name: rfhSP-D) that can be administered to preterm infants born at less than 28 weeks gestation, and to help identify whether this can prevent the development of neonatal chronic lung disease.

Dyspnea is defined by a subjective sensation of respiratory discomfort, the intensity of which varies according to the terrain, the anamnesis and the cause. Resuscitation is associated with many causes of dyspnea, including initial distress, mechanical ventilation, or after-effects following the pathology and its management. Respiratory distress is the most severe form of impaired lung function. It is the first cause of hospitalization in intensive care. This distress, indicative of the failure of the respiratory system, is always severe and potentially fatal. It therefore constitutes an absolute therapeutic emergency. Dyspnea is often the revealing symptom of the condition and the urgency surrounding its management is an additional factor of concern for the patient. As a result, dyspnea is a pejorative element associated with severity or even death. In patients surviving the initial condition, dyspnea persists and can be found months or even years later, despite the initial rehabilitation. It is strongly associated with anxiety or even the fear of dying and contributes to the occurrence of post-traumatic stress syndromes. This persistent sensation of respiratory discomfort, limiting the patient's autonomy in his activities of daily living, seems to be able to reduce his quality of life. In addition, the perpetuation of this dyspnea could favor a spiral of deconditioning causing a progressive deterioration of the cardio-respiratory system justifying new hospitalizations. In patients with chronic respiratory failure, exercise rehabilitation supervised by hysiotherapists allows, in addition to improving autonomy, a significant reduction in dyspnoea, thus increasing the quality of life of these patients. The main objective of this study is to evaluate the effect at 2 years of 3 modes of management of dyspnea: exercise rehabilitation, standard physiotherapy and "usual care" on post-resuscitation dyspnea in patients with presented with severe COVID-19.

Thirty -one confirmed Severe Acute Respiratory Syndrome CoronaVirus 2 (SARS-CoV-2 ) infected patients with Acute Respiratory Distress Syndrome (ARDS) and placed in prone position(PP) for 3 times (PP1, PP2, PP3)consecutively will be included. Arterial blood gases (ABG), partial pressure of arterial oxygen/ fraction of inspired oxygen (PaO2/FiO2 ) ratios, partial pressure of carbondioxide (PaCO2), positive end expiratory pressure (PEEP), and fraction of inspired oxygen (FiO2) values will be recorded before (bPP), during (dPP)and after (aPP) every prone positioning. Eye, skin, nerve and tube complications related to prone positions wll be recorded

Despite almost universal usage of supplemental oxygen therapy in patients presenting in the emergency department with traumatic brain injury (TBI), optimal oxygen levels are unclear. The investigators propose a pilot multi-center randomized controlled trial to test the hypothesis that maintaining intermediate normal as opposed to high normal oxygen levels in patients presenting in the emergency department with TBI is feasible, and to obtain preliminary data on the efficacy of the two approaches to oxygen therapy. The aim is that the investigators produce pilot data, which could inform the design of potential subsequent larger clinical trials.

This study seeks to define the ultrasound profile of patients with COVID-19, and document the progression of these ultrasound findings to develop prognostication and clinical decision instruments that can help guide management of patient with COVID-19. Primary aims include the development of ARDS, refractory hypoxemia, acute cardiac injury, pulmonary embolism, pneumothorax or death. Secondary aims include potential change in CT and plain film utilization given the use of POCUS, as well as emergency department and inpatient LOS (length of stay).
