This study is an interventional, non-pharmacological, multicentric, randomized, controlled, superiority, non-profit study. Its primary objective is to evaluate if the administration of surfactant based on FOT assessment will allow a 5-day reduction in the duration of respiratory support as compared to standard practice in preterm infants between 27+0 and 32+6 weeks' gestation. The secondary objectives are: 1. to determine if a lung mechanics-based approach for administering surfactant will change treatment timing; and 2. to assess the impact of the novel approach on other neonatal general outcomes. The study will take place within the neonatal intensive care units. Non-invasive respiratory support will be delivered by nasal CPAP with a starting pressure of 5-8 cmH2O. FiO2 will be titrated in order to achieve the target SpO2 91-95%. Infants matching the clinical criteria for inclusion will be randomized in two arms following the current data protection and confidentiality regulations. Central, computer-generated randomization (allocation 1:1) with variable block sizes according to gestational age will be used. Infants will be stratified according to gestational age (27+0 -28+6 weeks; 29+0 -30+6 weeks; 31+0 -32+6 weeks) and center. Study Arms: A) Surfactant administration following oxygenation-based criteria (clinical assessment) (control) B) Surfactant administration following both lung mechanics assessment OR oxygenation-based criteria (clinical assessment) (intervention).
Biliary atresia is a serious congenital anomaly characterized by persistent and progressive cholestatic jaundice. The incidence of biliary atresia is more common in East Asia, especially China, with an incidence of 2 per 10,000 live births. Liver transplantation is the only effective way to treat end-stage liver disease. However, distant organ damage, affecting the heart, brain, kidneys, lungs, and intestines, is still an important factor affecting the long-term survival of children after surgery. Desflurane is a volatile anesthetic commonly used in surgery. In order to observe the effect of desflurane on the incidence of early postoperative pediatric acute respiratory distress syndrome (PARDS) with biliary atresia who underwent living donor liver transplantation, and explore the related mechanism, a total of 165 infant patients underwent living liver transplantation due to biliary atresia from March 2023 to October 2023 are included in our single-center prospective study. They are randomly divided into propofol group (n=55), propofol and desflurane group (n=55) and desflurane group (n=55) according to the difference of intraoperative anesthesia maintenance. Gender, age, height, weight, PELD scores and other preoperative basic data are recorded. Operation time, anhepatic time and intraoperative blood loss volume are recorded. The basic information of liver donors are also recorded. Postoperative mechanical ventilation time, ICU stay time, tacrolimus concentration, total length of hospital stay and mortality during hospitalization are recorded. According to the the definition of PARDS recommended by the 2015 Pediatric Acute Lung Injury Consensus Conference is used as the diagnostic and grading criteria for postoperative PARDS, and the incidence and grading of PARDS within the first seven days after surgery are evaluated in the three groups. Peripheral blood is collected immediately after anesthesia induction, 30min after reperfusion and at the end of surgery to detect serum levels of HMGB1, IL-6 and TNF-α by enzyme linked immunosorbent assay (ELISA).
This study aims to investigate the quality of life and the outcome after veno-venous extracoporeal membrane oxygenation (ECMO) support fir severe acute respiratory syndrome (ARDS) in COVID-19 patients.
A multicenter prospective study was conducted to compare the predictive value of 6-zone, 10-zone, and 12-zone LUS scores for PS application in early and late preterm infants.
Acute respiratory distress syndrome (ARDS) is often complicated by right ventricular dysfunction (RVD), Acute cor pulmonale is the most serious form of ARDS complicated with RVD.Levosimendan is indicated for short-term treatment of acute decompensated heart failure that is not responding well to conventional therapy and requires increased myocardial contractile force.In 2016, the European Society of Cardiology issued recommendations for the management of acute right heart failure, stating that levosimendan can improve right ventriculo-pulmonary artery coupling by both increasing right heart contractility and reducing pulmonary vascular resistance.However, the clinical application of levosimendan in the treatment of ARDS right heart dysfunction is insufficient.Therefore, this study intends to use transesophageal ultrasound to evaluate right ventricular function, reduce the limitation of poor right ventricular window in transthoracic echocardiography, and conduct a multi-center randomized controlled study to further explore the effects of levosimendan on right ventricular function in ARDS patients, such as tricuspid ring systolic displacement (TAPSE) and tricuspid ring systolic displacement velocity (S '). Effects of right ventricular area change fraction (RV FAC), right ventricular end-diastolic area/left ventricular end-diastolic area (RVEDA/LVEDA), pulmonary circulation resistance (PVR), hemodynamics and mortality.
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: 1. How does the immune system respond to different kinds of lung injury and inflammation and how do those processes differ from each other? 2. 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)? 3. 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 patients breathe) because they have ARDS or are on a mechanical ventilator for some other reason (control group). The following will happen: 1. Participants will be given 100% oxygen through the breathing machine (mechanical ventilator) for 3-5 minutes. This is called pre-oxygenation. 2. 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. 3. The fluid will be removed with suction and will be sent to the laboratory for testing. 4. This will be repeated two more times over the course of 10 days, or less if participants are taken off of the ventilator. The procedure will be performed no more than three times. 5. Two nasal brushings will be taken from the participants' nose. 6. Approximately 3 tablespoons of blood will be removed by putting a needle into the participants 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 7. Data including the participants age, sex, severity of illness, and other medical conditions will be recorded to determine how these can affect the white blood cells. 8. If bacteria are isolated from the fluid in the participants lung, the participants' physician may choose to place the participants on antibiotics to treat an infection. 9. A follow-up phone call may be made by a member of the research team after discharge from the hospital. At this time, the participant may be invited to participate in the Post-ICU clinic at National Jewish Health.
Low tidal volume ventilation (LTV) has been proposed and widely used in patients with acute respiratory distress syndrome (ARDS) to prevent ventilator-induced lung injury (VILI) and mitigate its effects. The LTV strategy is intended to protect the "baby lung" from overdistension while simultaneously allowing acutely injured tissue to continually collapse. Airway pressure release ventilation (APRV) is a highly effective strategy improving lung recruitment and oxygenation in clinical studies, but its effects on lung injury and mortality is debatable. Animal studies revealed that APRV could normalize post-injury heterogeneity and reduce the risk of VILI. Our objective was to investigate the impact of APRV and LTV on regional ventilation and perfusion distribution in ARDS patients by electrical impedance tomography (EIT).
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.
The goal of this observational study is to evaluate new non-invasive passive surveillance technologies, Level 42 AI imPulse™ Una and TOR devices for the detection of COVID-19, Flu, and/or RSV in asymptomatic and symptomatic individuals over age of 18 undergoing COVID-19, Flu, and/or RSV screening and testing at BAMC Ft Sam Houston, TX; with and without COVID-19, Flu, and/or RSV. The hypotheses are: (H1) The imPulseTM Una and the imPulseTM TOR e-stethoscopes have at least a similar discriminative and detection ability among symptomatic and asymptomatic COVID-19 carrier versus those not infected compared to gold standard RT-PCR. We will operationalize and deploy both the imPulseTM Una and imPulseTM TOR e-stethoscope into DoD use-cases and compare their usability between the devices. (H2) Identify if the imPulseTM Una and the imPulseTM TOR e-stethoscopes have at least a similar discriminative and detection ability among symptomatic and asymptomatic Respiratory Syncytial Virus (RSV), Influenza and Long COVID carriers versus those not infected compared to gold standard Rapid RSV and Flu Antigen Tests, or RT-PCR and molecular assays. We will operationalize and deploy both the imPulseTM Una and imPulseTM TOR e-stethoscope into DoD use-cases and compare their captured traces in the early identification of disease/illness analyzed by the devices built in algorithms. (H3) In the mid to long-term, this approach will also be explored as a diagnostic system to explore pursue the physical (structural and mechanical) properties of cells and tissues that maintain normal cell behavior (motility, growth, apoptosis), and the critical importance of the ability of cells to sense and respond to mechanical stresses, which will be operationally critical for assessment of both traumatic and unconventional exposures in austere environments. Participants will: - Be consented; - Be screened for COVID-19, Flu, and/or RSV symptoms according to BAMC's current screening procedures; - Have study data collected; - Complete a symptoms questionnaire; - imPulseTM Una and TOR e-stethoscopes examination will be conducted; - Participants will be compensated for completing all study requirements. (Active-Duty personnel must complete the study procedures while off-duty in order to receive compensation.)
