Filter by:The lung is at risk for ischemic insults during total cardiopulmonary bypass because lung perfusion is maintained solely by the bronchial arterial system
The aim of this study is to determine the prevalence of ventilator-associated events (VAE). To analyze the patients profile, morbidity and mortality compared to patients who did not develope VAE. The preventability of VAE will be assessed by comparing the percentage of adherence to the bundle of preventive measures among patients who developed and did not develope VAE.
The purpose of this study is to investigate whether the use of inhaled anesthetics, compared to intravenous anesthetics, can affect the amount of lung inflammation and postoperative respiratory complications seen after cardiac surgery.
The purpose of this study is to determine whether L-citrulline is effective and safe in the prevention of clinical sequelae of Acute Lung Injury in pediatric subjects undergoing surgery for congenital heart defects.
Background: In patients undergoing lung lobectomy, lung collapse and re-expansion after resection is associated to severe oxidative lung injury. The researchers hypothesized that remote ischemic preconditioning (RIPC) could reduce oxidative lung injury and improve the oxygenation parameters. Methods: We designed a single-centre, randomized, prospective and double-blind study, conducted in fifty-three patients with non-small cell lung cancer undergoing elective lung lobectomy. Fifty-three patients were randomly assigned to 2 groups: 26 patients received limb RIPC (3 cycles: 5 min ischemia/5 min reperfusion induced by an ischemia cuff applied on the thigh) and 27 controls. Time course of oxidative stress marker levels was simultaneously studied in exhaled breath condensate (EBC) and blood at four specific time points: T0, pre-operatively; T1, during operated lung collapse and one-lung ventilation (OLV); T2, immediately after resuming two-lung ventilation (TLV); T3, 120 min after resuming TLV. EBC 8-isoprostane was the primary outcome. Secondary outcomes included PaO2/FiO2, other pulmonary oxygenation variables, other oxidative markers (NO2-+NO3-, H2O2) and pH.
Asynchrony during mechanical ventilation has been poorly described in patients suffering from acute respiratory distress syndrome. The purpose of this study is to describe the frequency of asynchronies (ineffective efforts and double triggering) in these group and evaluate potential risk factors and prognosis implications.
Study conducted to confirm phrenic nerve stimulation using the Lungpacer LIVE Catheter, confirm capture of the diaphragm and confirm that the diaphragm can be paced in synchrony with mechanical ventilator breaths.
Transfusions cause more adverse events in children than in adults. Patients in pediatric intensive care units (PICU) are particularly exposed to transfusions of plasma-rich blood products (red blood cell (RBC), plasma and platelets) and the risk of adverse events after a transfusion is particularly high in this vulnerable population. Transfusion-related acute lung injury (TRALI), an acute inflammation of the lungs that impairs gas exchange leading to acute respiratory failure, is one of the 2 most deadly transfusion complications in the general population. There is limited evidence on TRALI incidence and impact in critically ill children. This reduces the awareness of PICU team for this complication, and makes the decision process to transfuse particularly difficult. Moreover, acute lung injury is highly prevalent in critically ill children. It is therefore complex to ascertain if the high frequency of respiratory deteriorations observed after a transfusion in PICU is explained by the transfusion itself or by the evolution of the patient's critical illness. The investigators will conduct a cohort study of consecutive transfused critically ill children, with a control group of matched non-transfused children. The primary objective is to determine if transfusion of RBC, plasma and/or platelets in PICU is an independent risk factor of TRALI, and to compare the respiratory evolution in the two matched (transfused and non-transfused) groups. The secondary objectives will include the determination of the incidence rate, risk factors and clinical impact of TRALI in transfused PICU patients. The investigators will study both "classic TRALI" and "delayed TRALI".
This study is a prospective, non-randomized sequential cohort, open label, multi-center, non-inferiority, Phase IV surveillance study following transfusion of INTERCEPT PCs. The patient population will be hematology-oncology patients, including those undergoing hematopoietic stem cell transplant (HSCT), expected to require one or more PC transfusions. For each participating center, the study will start with a brief pilot run-in period with a group of at least 5 patients exposed only to conventional PCs. The purpose of this pilot run-in is to evaluate study logistics and data collection methods within each study center. Data from the pilot phase will be included in the data analysis for the treatment comparison. After the pilot run-in period, the study will be conducted in two sequential patient cohorts: 1) the Control cohort during which study patients will receive only conventional PCs, and 2) the INTERCEPT cohort during which patients will receive only INTERCEPT PCs. Patient enrollment at each Center will be monitored to target similar numbers of patients into the Control and Test Cohorts within each center. Centers may enroll Control and Test patients in ratios that vary from 2:1 to 1:2 due to institutional requirements to move rapidly to full INTERCEPT implementation, or due to availability issues with either Test or Control components. Within each Center, patient enrollment will be stratified in four categories: (1) chemotherapy only; and by use of conditioning regimens for hematopoietic stem cell transplantation (HSCT) in (2) myeloablative conditioning, (3) non-myeloablative conditioning, and (4) reduced intensity using the Center for International Blood and Marrow Transplant Research (CIBMTR) criteria. Note time from last chemotherapy treatment to first study transfusion should be no more than 30 days. To ensure both Test and Control cohorts have a similar allocation ratio (±10% per category) among the conditioning regimen strata, enrollment caps will be set for the Test cohorts, hence no Test patients will be enrolled to a stratum once the cap for the given stratum is met. Eligible patients will be enrolled in open Test strata sequentially as long as there is sufficient Test PC inventory available. Enrollment may be delayed for the Test cohort if sufficient inventory of Test PCs is not available.
The purpose of the present study is to visualize the inflammatory response and coagulation disorders during cardiac surgery in order to identify possible predictors for acute lung injury postoperatively.
