Filter by:The purpose of this study is to evaluate the safety and efficacy of the Hemolung Respiratory Assist System in patients with hypercapnic respiratory failure associated with acute exacerbation of chronic obstructive pulmonary disease (COPD) and a 50% likelihood of failure of noninvasive positive pressure ventilation leading to intubation and mechanical ventilation.
The purpose of this study is to determine whether inhaled iloprost is safe and effective in pediatric patients with pulmonary hypertension who are sick in the intensive care unit.
Child extubation failure range from 4.1% to 19%. Studies in adults and children showed that extubation failure increases mortality mainly in those who need reintubation as this is a invasive procedure associated with many complications. Therefore, patients are reintubated when they worsen, which can contribute to organ dysfunction and increased mortality. Positive Pressure Noninvasive ventilation (PPNIV) has been proposed as a way to treat acute respiratory distress, avoiding complications of intubation and invasive ventilation. Most of the studies in adults are not conclusive on the benefits of PPNIV as a way to treat post-extubation acute respiratory distress. However, studies that evaluated the early use of PPNIV in post-extubation period as a way to prevent respiratory failure tend to show some advantages as decrease of reintubation, decrease number of respiratory distress, decrease of hospital infection frequency and lower mortality rate in the intensive care unit (ICU) for those who use PPNIV. In a prospective study on the use of PPNIV in 114 children, Essouri at al avoided invasive ventilation in 77%, being the group in patients with post-extubation respiratory distress. As far as the investigators know there is not any randomized, controlled study in children examining the PPNIV as a way to prevent post-extubation respiratory distress. The investigators' hypothesis is that PPNIV decreases the extubation failure rate and, as a consequence, the Pediatric Intensive Care Unit (PICU) and hospital length of stay, and mortality rate. The objective is to compare PPNIV and inhalatory O2 (catheter or facial mask) in children after extubation, evaluating the need of reintubation, hospital and PICU mortality rate and length of stay in PICU and hospital.
Acute Respiratory Failure (ARF) requiring mechanical ventilation affects 1.1 million of the 4.4 million people admitted to United States Intensive Care Units (ICU) every year. Patients with ARF have an average ICU and hospital length of stay (LOS) of 8 and 15 days, respectively, with median hospital costs greater than $30,000 United States. Patients with ARF experience deconditioning, muscle weakness, joint contractures, dyspnea, depression, and reduced health-related quality of life, all of which may contribute to prolonged hospitalization and increased costs. Mechanistically, it is understood that patients with ARF demonstrate acute inflammation which may contribute to the above cited problems. While the investigators' research and that of others has shown that rehabilitation therapy can increase functional outcomes while lowering biomarkers of inflammation in the frail aged and other clinical populations, it is not known whether such rehabilitation therapy can result in improved functional capacity and functional performance and reduce inflammation in ARF patients. There is previous evidence for the feasibility and safety of rehabilitation therapy in ARF patients. Therefore, the investigators propose a two-arm, randomized trial in 326 patients with ARF to compare Standardized Rehabilitation Therapy initiated in the ICU and administered throughout the hospitalization versus usual care (control). Standardized Rehabilitation Therapy will consist of: passive range of motion, physical therapy and progressive resistance exercise (strength training). The regimen will be administered 7 days/week by a Mobility Team consisting of a critical care nurse, physical therapist and nursing assistant. The investigators will determine whether standardized rehabilitation therapy will reduce hospital LOS, improve functional capacity and performance, improve quality of life, reduce inflammation and reduce hospital costs as compared to usual care. This study's primary objective is to determine whether standardized rehabilitation therapy will decrease hospital length of stay. Hypothesis: Compared to usual care, standardized rehabilitation therapy will reduce hospital length of stay for patients with Acute Respiratory Failure.
The purpose of this study is to determine the safety and efficacy of citrate to provide anticoagulation of an ECMO circuit without patient anticoagulation. The standard method of providing ECMO circuit anticoagulation is the use of heparin which also anticoagulates the patient and increases the risk of patient bleeding.
The purpose of this study is to study the effects of a complex pulmonary rehabilitation program on mobility measured by 6 minute walking distance (6MWD) and physical activity, measured via Dynaport and Actibelt Aktivitätsmonitor, dyspnoea (VAS), quality of life (HRQL (SF36, EuroQul)), anxiety and depression (HADS)and PaCO2-behavior under physical activity.
The aim of this study is to compare two methods of delivery of noninvasive mechanical ventilation (NIV). Since patient compliance and mechanical characteristics of the delivery devices are two fundamental variables in the success of NIV during acute respiratory failure, our hypothesis is that an improved patient-ventilator interface may improve the efficacy of therapy.
Patients undergoing intubation and mechanical ventilation require removal of secretion by means of trachoebronchial suctioning. Timing of the procedure is mainly based on clinical parameters. TBA Care® is a new commercially available device designed to generate a signal when secretions are present in the respiratory tract of intubated patients, thus indicating the need for endotracheal suctioning only when necessary and prior to clinical deterioration. In a prospective randomized trial in intubated and mechanically ventilated patients of a general ICU the researchers investigated the efficacy of TBA Care® in detecting the presence of retained secretions compared to the standard indicators.
The study is aimed to assess the possible benefit of non-positive pressure mechanical support in front of conventional ventilation in patients admitted to the intensive care unit (ICU) because of pure hypoxemic respiratory failure.
Background/Objectives: Acute hypoxemic respiratory failure (AHRF) is a frequent cause of pediatric ICU admission. Early treatment with inhaled nitric oxide (iNO) plus conventional mechanical ventilation (CMV) improves oxygenation, responsiveness being significantly influenced by alveolar recruitment level. High-frequency oscillatory ventilation (HFV) is conceptually very attractive as constant mean airway pressure optimizes lung recruitment; this could maximize iNO effects. Aims: To analyze the effects of HFV on oxygenation indexes in AHRF children under CMV and iNO. Methods: Children with AHRF (oxygenation index ≥10) aged between one month and 14 years under CMV with PEEP≥10cmH2O and 5ppm iNO for 1h were randomly assigned to CMV (CMVG, n=12) or HFV (HFVG, n=12) in a crossover design. Children with chronic cardiac or pulmonary diseases were excluded. Patients were kept under one of the two ventilation modes for 8h, crossing to the other for 8h, and then back again to complete 24h observation. Blood gas analysis, oxygenation indexes, and hemodynamic variables were recorded at enrollment (Tind), 1h after iNO start and then every 4h (T4h etc). The Mann-Whitney U test compared group ages and PRISM scores, and the Fisher test genders. Moments and groups were compared by repeated measure analysis for independent groups. Significance was considered at p<0.05.
