Active clinical trials for "Respiratory Distress Syndrome, Newborn"

The primary endpoint of this research is to establish that the alveolar dead space is significantly higher in patients with COVID-19 ARDS, compared to patients with non-COVID-19 ARDS. Secondarily, the investigators want to establish the prognostic value of the alveolar-dead space (measured iteratively) in patients with COVID-19 and non-COVID-19 ARDS, to establish the respective influences of the biological parameters of endothelial damage, of the biological parameters of coagulopathy, of the parameters set on the artificial ventilator on the value of the alveolar dead space; in ARDS patients with COVID-19 and non-COVID-19 ARDS, to establish the prognostic value of the laboratory parameters of endothelial damage and coagulopathy in patients with COVID-19 and non-COVID-19 ARDS.

Mortality rates in children with pediatric acute respiratory distress syndrome (PARDS) are higher in Asia compared to other regions. In adults with acute respiratory distress syndrome, the only therapy that improves mortality rates is a lung protective ventilation strategy. The pediatric ventilation recommendations are extrapolated from evidence in adults, including ventilation with low tidal volume, low peak/plateau pressures and high-end expiratory pressure. A recent retrospective study of ventilation practices in Asia showed varying practices with regards to pulmonary and non-pulmonary therapies, including ventilation. This study aims to determine the prevalence and outcomes of PARDS in the Pediatric Acute and Critical Care Medicine Asian Network (PACCMAN). This study will also determine the use of pulmonary (mechanical ventilation, steroids, neuromuscular blockade, surfactant, pulmonary vasodilators, prone positioning) and non-pulmonary (nutrition, sedation, fluid management, transfusion) PARDS therapies. To achieve this aim, a prospective observational study which involves systematic screening of all pediatric intensive care unit (PICU) admissions and collection of pertinent clinical data will be conducted. Recruitment will be consecutive and follow up will continue to intensive care discharge.

Blood which recirculates through the circuit of a veno-venous Extracorporeal Membrane Oxygenation (V-V ECMO) does not contribute to the systemic oxygenation of a patient on V-V ECMO and is called the recirculation fraction (Rf). Theoretically, the optimization of ECMO blood flow is possible using Rf measurements. A prospective, observational study will be performed measuring the Rf of total ECMO blood flow in patients with acute respiratory distress syndrome (ARDS) on V-V ECMO with an ultrasound dilution technique. ECMO blood flow will be optimized by reducing ECMO blood flow in accordance with the measured Rf as long as systemic oxygenation is not compromised.

Introduction: Sepsis-induced acute respiratory distress syndrome(SI-ARDS) is a common complication of severe sepsis and is an independent contributor to poor prognosis of patients. It remains a clinical challenge to identify the SI-ARDS early and accurately, which could optimize the treatment strategy and reduce the mortality risk. Radiomics high-dimensional features extracted from CT images offer an insight into microvascular damage of SI-ARDS that are imperceptible to human eyes and aspects of intra-alveolar heterogeneity with potential prognostic relevance. Methods: Study design Investigators screened all patients with sepsis and septic shock who are treated in Sun Yat-sen Memorial Hospital, Sun Yat-sen University during the period from 1 May 2015 and 30 May 2022. Patients were recruited retrospectively from May 2015 to April 2021 as discovering group, and prospectively during the period from May 2021 to May 2022 as validation group. Follow-up will conducted until April 2023. Cohort descriptions and definitions Investigators plan to recruit 160 patients in discovering group, 40 patients in internal validation group, and 100 patients in external validation group. Patients between 18 and 80 years of age with sepsis and septic shock will be screened for eligibility. SI-ARDS is defined by sequential occurrence of the sepsis-3 consensus criteria for sepsis and the Berlin Definition for ARDS. The exclusion criteria are： admission stay <24hours, the presence of end-stage lung disease or long-term oxygen therapy, critically ill patients who have started mechanical ventilation caused by SI-ARDS before admission, a history of lung transplantation and chronic obstructive pulmonary disease, cancer patients not/have received chemotherapy. Outcome measures In this study, the primary outcome measure was the occurrence rates of acute respiratory distress syndrome(ARDS). It refers to the occurrence of sepsis patients progressed into ARDS. Secondary outcome measures were as follows: 1.28-day mortality 2.ventilator-free days 3.respiratory failure-free days Data collection All clinical data were collected by investigators and trained personnel. Each participant's data will be filled in electronic case report forms (CRF) and store online using REDCap (Research Electronic Data Capture). Discussion: SI-ARDS is one common severe complication with critically ill sepsis patients, which causes high mortality and poor prognosis. Early ARDS patient(arterial oxygen tension/inspired oxygen fraction [PaO2/FIO2] ≤ 300 mmHg but > 200 mmHg) may not require invasive mechanical ventilation, and is more readily reversible than acute respiratory distress syndrome(ARDS). In this ambispecive cohort study, investigators developed and validated novel nomograms incorporating the radiomics signature and clinical signature to provide an easy-to-use and individualized prediction of SI-ARDS occurrence and severe degree in patients with early stage.

Children supported by Extra-Corporeal Membrane Oxygenation (ECMO) present a high risk of neurological complications and cerebral autoregulation (CA) impairment may be a risk factor. The first objective is to investigate the association between CA impairments and neurological outcome assessed by the onset of an ANE. The secondary objective is to study the underlying mechanisms influencing CA.

For the last years, studies have described the " Post-intensive care Syndrome " (PICS), which consists in alteration of quality of life, cognition, autonomy and psychological disorders within the months after intensive-care. Patients with COVID-19 in intensive care units are at high risks to develop PICS. The primary objective is to analyse the incidence of the post-traumatic stress disorder at 12 months after intensive-care for a COVID-19 Acute Respiratory Distress Syndrome (ARDS).

Non-invasive respiratory support methods have been widely used in premature babies with respiratory distress syndrome (RDS) which has changed the basic management of premature babies in the early period. According to the 2019 European Guidelines on RDS management, early nasal CPAP is recommended as first-line therapy in infants <30 weeks of age who are at risk of RDS who do not require mechanical ventilation (MV). However, some of the premature babies have faced non-invasive ventilation failure. Remarkably, infants who experience non-invasive ventilation failure are at increased risk of death, pneumothorax, intraventricular hemorrhage, and bronchopulmonary dysplasia (BPD), among other morbidities. In non-invasive ventilation failure, although demographic factors such as small gestational age, low birth weight, and male gender play a role, it has been suggested that surfactant deficiency may also play an important role. The most frequently reported risk factor in predicting non-invasive failure in studies is the fraction of inspiring oxygen during the first hours of life. In addition, positive end-expiratory airway pressure (PEEP) required for patient stabilization was found to be a potential predictor. However, there are still limited data to predict non-invasive ventilation failure. "Which newborns are at high risk for non-invasive ventilation failure?" and "When should the surfactant be applied?". The study is a single-center, prospective study to evaluate prognostic factors, and most importantly to define the FiO2 threshold, which is an indicator of possible non-invasive ventilation failure in infants supported with nasal intermittent positive pressure ventilation.

Five percent of patients with COVID-19 progressed to respiratory failure and required ICU admission, such patients often have abnormal oxygen tolerance. However, there is still a lack of clinical indicators to predict the prognosis and treatment responsiveness of COVID-19.

Teleconsultation, or the use of video telecommunications technology to deliver expert recommendations for care remotely, has been used to improve the safety and quality of emergency care for children in hospital-based acute care settings by providing real-time access to remote pediatric physician experts. Whether extending teleconsultation as a patient safety intervention to emergency medical systems (EMS) outside hospitals can similarly benefit sick and injured children in the community is unknown. Advances in mobile technology have made teleconsultation more accessible and affordable for EMS systems. However, this intervention has been underutilized by EMS partially due to the lack of prehospital research supporting its efficacy for pediatric applications. In prior simulation studies, the investigators found high intervention acceptance among key stakeholder groups (pediatric emergency physicians and paramedics), and demonstrated that it was feasible to integrate video communication into prehospital clinical workflows involving critical care delivery in high-risk pediatric scenarios. These initial simulation studies were conducted in a controlled prehospital setting in static ambulances using infant simulator manikins to minimize risk to children and providers. Demonstrating feasibility and acceptability with real children in moving ambulances is the next step to build the necessary evidence base to support future planned prehospital efficacy trials with children. The investigators hypothesize that remote respiratory assessment of children by medical control physicians (expert physicians) using a mobile teleconsultation platform is acceptable to users (physicians and transport providers), and technically feasible in real transports.

This study will investigate how different types of routine sedation may affect patient's breathing whilst on a ventilator in the Intensive Care Unit (ICU). There are different approaches to sedation which may have advantages and disadvantages. During the study patients will receive both intravenous and inhaled volatile sedation (similar to anaesthetic 'gases' used for general anaesthesia) and the drive to breath, breathing efforts and function of the lung will be assessed.
