Filter by:Preterm neonates born at less than 30 weeks' gestation are commonly maintained on invasive or non-invasive respiratory support to facilitate gas exchange. While non-invasive respiratory support (NIS) can be gradually reduced over time as the infant grows, most weaning strategies often lead to weaning failure. This failure is evidenced by an increase in significant events such as apneas, desaturations, and/or bradycardias, increased work of breathing, or an inability to oxygenate or ventilate, resulting in escalated respiratory support. Although the optimal approach to weaning NIS remains uncertain, neonatal units that delay Continuous Positive Airway Pressure (CPAP) weaning until 32-34 weeks corrected gestational age exhibit lower rates of chronic lung disease. Therefore, the investigators aim to compare the duration on respiratory support and oxygen exposure in infants born at less than 30 weeks' gestational age who undergo a structured weaning protocol that includes remaining on CPAP until at least 32-34 weeks corrected gestational age (CGA). The hypothesis posits that preterm infants following a structured weaning protocol, including maintaining CPAP until a specific gestational age, will demonstrate lower rates of weaning failure off CPAP (defined as requiring more support and/or experiencing increased stimulation events 72 hours after CPAP weaning) than those managed according to the medical team's discretion.
The study aims to find if using a Biphasic Cuirass Ventilation is as effective as using a Non invasive Positive Pressure Ventilation in patients admitted with acute hypercapnic respiratory failure.
High-flow nasal oxygen therapy (HFNO) is an oxygenation technique frequently used in intensive care. The main objective of our study is to show that the use of a protocol for weaning patients off high-flow nasal oxygen therapy (HFNO) in the intensive care unit increases the probability that patients will be weaned from HFNO at Day 7 post-randomisation. This is a open-label multicentre randomised controlled trial conducted in two parallel groups. The primary endpoint is the success rate at Day 7, with success defined as "definitive" weaning from HFNO, i.e. patients weaned from HFNO for more than 48 hours without recourse to non-invasive ventilation (NIV) or intubation and still alive at Day 7. The weaning protocol will be started as soon as the patient meets all the inclusion criteria, considered to be the prerequisites for initiating weaning from HFNO. Patients will be monitored until Day 28 maximum.
This is a multicenter study to test a decision-making support process for families and clinicians facing decisions about chronic home ventilation for a child. The investigators hypothesize that the intervention will increase family preparedness for decision-making and will improve clinician-family shared-decision making. Half of families will be assigned to "usual care" arm and half to the "intervention" arm. Intervention families will view the study website with study staff and will answer questions related to website content. All families will be interviewed and surveyed at 1, 6 and 12 months after enrollment. Each family will designate 1-2 physician involved in the decision about home ventilation; each physician will be interviewed and surveyed at 1 month.
Ultrasound of the diaphragm is an easily reproducible bedside tool that provides a non-invasive measurement of inspiratory muscle function and respiratory efficiency. The diaphragmatic thickness correlates with the strength and muscle shortening and is reflective of its contribution to the respiratory workload. Diaphragm thickening fraction (DTF) has been shown to be predictive of extubation failure in ventilated patients. However, whether measurements of DTF are predictive of high flow nasal cannula (HFNC) outcomes in patients with acute hypoxemic respiratory failure (AHRF) remains unknown. The objective of this study is to identify predictors of HFNC failure by diaphragm ultrasound and to compare its performance with the well-established ROX index.
Right ventricular dysfunction (RVD) and right ventricular-pulmonary arterial (RV-PA) uncoupling detected by transthoracic echocardiography (TTE) in acute respiratory distress syndrome (ARDS) are associated with poor survival. Early detection of RVD and RV-PA uncoupling in patients with acute hypoxemic respiratory failure (AHRF) may be indicative of worsening and decompensating pulmonary condition which may require escalation of respiratory support. The use of TTE parameters in predicting high-flow nasal cannula (HFNC) failure has not been previously studied. The objective of this study is to identify predictors of HFNC failure by TTE and to compare its performance with the well-established ROX index.
ARDS is an acutely induced respiratory failure characterized by the appearance of bilateral alveolar opacities on imaging and hypoxemia Etiologies are divided into two classes: pulmonary, including all infectious pathologies, aspiration pneumonia, and drowning, and extra-pulmonary, induced by sepsis or acute pancreatitis. The mortality rate of ARDS remains high in unselected patient populations Among strategies that have proven beneficial in terms of patient outcome, prone positioning (PP) is associated with the greatest impact in terms of reduction in mortality. PP is currently recommended in the European guidelines for ARDS associated with a PaO2/FiO2 ratio < 150 mmHg in patients in whom ventilatory settings have been optimized beforehand, The failure of early PP studies to demonstrate a survival benefit in ARDS was attributed to insufficient session duration. The PROSEVA study was the first to demonstrate that a PP duration of 17 h is associated with a reduction in mortality During the COVID-19 pandemic, several centers have reported the implementation of longer PP sessions. Two strategies have emerged from these studies. In one case, the patient was left in the prone position until the criteria for stopping PP were met. Thus, the PP/supine position alternation was completely suppressed. In another published strategy, PP sessions were maintained for a period covering two nights. Furthermore, in a multicenter retrospective study, PP sessions were maintained until clinical improvement was associated with reduced mortality. In this study of 263 patients, the median duration of PP in the extended duration group was 40 h, and 75% of the sessions lasted 48 h or less. Using a propensity score, the authors showed that patients treated with an extended PP duration had a lower 3-month mortality rate than patients in the standard duration group . This protocol was also associated with a 29% cumulative incidence of pressure sores, similar to the 25% cumulative incidence reported in the PROSEVA study Other data published on pressure sores and PP of duration > 24 hours are also reassuring. Finally, a recent review recently reported that an extended PP session of > 24 h had also been used before the COVID-19 pandemic. PP sessions had a median duration of 47-78 hours and were applied mainly to ARDS secondary to community-acquired pneumonia. All pre-COVID studies were retrospective, monocentric, without a control group.
The aim of the study is to evaluate the effect of opioids administered during sedation on patients' respiratory activity (ventilation) and comfort of the operator and patient during the endoscopic procedure. A common side effect of sedation is the effect on patients' ventilation, resulting from a combination of attenuation of respiratory centre activity and loss of patent airways. Shallow sedation will reduce these risks, but in addition to patient discomfort, it also increases the difficulty or impossibility of the endoscopist to perform the procedure. Choosing the appropriate method of sedation thus fundamentally affects the course of the procedure from the point of view of both the patient and the endoscopist. The aim is to prove that sedation with propofol alone compared to sedation with propofol and fentanyl premedication leads to the need for higher cumulative doses of administered propofol, higher risk of respiratory depression and lower patient and operator comfort. In addition, the non-invasive respiratory volume monitor (ExSpiron 2Xi) will be used for standard patient monitoring during the procedure, which assesses the lung tidal volume and respiratory rate by measuring the electrical impedance of the chest. This measurement captures inadequate ventilation before saturation drops, allowing even slight differences between selected drugs to be compared.
The goal of this observational study is to establish an intelligent early warning system for acute and critical complications of the respiratory system such as pulmonary embolism and respiratory failure. Based on the electronic case database of the biomedical big data research center and the clinical real-world vital signs big data collected by wearable devices, the hybrid model architecture with multi-channel gated circulation unit neural network and deep neural network as the core is adopted, Mining the time series trends of multiple vital signs and their linkage change characteristics, integrating the structural nursing observation, laboratory examination and other multimodal clinical information to establish a prediction model, so as to improve patient safety, and lay the foundation for the later establishment of a higher-level and more comprehensive artificial intelligence clinical nursing decision support system. Issues addressed in this study 1. The big data of vital signs of patients collected in real-time by wearable devices were used to explore the internal relationship between the change trend of vital signs and postoperative complications (mainly including infection complications, respiratory failure, pulmonary embolism, cardiac arrest). Supplemented with necessary nursing observation, laboratory examination and other information, and use machine learning technology to build a prediction model of postoperative complications. 2. Develop the prediction model into software to provide auxiliary decision support for clinical medical staff, and lay the foundation for the later establishment of a higher-level and more comprehensive AI clinical decision support system.
Mechanical ventilation is a critical intervention in the management of pediatric patients with respiratory distress. During this process, accurate measurement of transpulmonary pressure (PL) is essential to ensure the safety and efficacy of ventilation. PL is defined as the difference between alveolar pressure (Palv) and pleural pressure (Ppl). While the direct measurement of Ppl is possible, it poses a risk to tissue integrity. Thus, the primary surrogate for Ppl measurement today is esophageal pressure (Pes). However, the measurement of Pes is not without challenges. This abstract outlines the pitfalls associated with Pes measurement, emphasizing the importance of employing well-defined procedures to mitigate potential errors. These errors can range from underestimation of Pes due to underfilled catheters to overestimation resulting from overfilled catheters. To address these challenges and optimize Pes measurement, various methods have been proposed for titrating the filling volume of the esophageal catheter. In this study, investigators aim to assess a faster decremental filling method and compare it to the traditionally accepted Mojoli method in the context of pediatric patients. This research seeks to enhance the intensivists' understanding of the most efficient and accurate approach to Pes measurement during mechanical ventilation in the pediatric population, ultimately contributing to improved patient care and outcomes
