High-Frequency Oscillatory Ventilation Associated With Inhaled Nitric Oxide in Children
Acute Hypoxemic Respiratory FailureBackground/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.
Effects of Remifentanil on Respiratory Function in Mechanically Ventilated Patients
Respiratory InsufficiencyRespiration2 moreSedation is widely used in mechanically ventilated patients. Propofol, benzodiazepines and opioids are the most used drugs. The study hypothesis is that sedation with remifentanil (an opioid drug) could improved respiratory pattern and effort in mechanically ventilated patients with rapid shallow breathing or high respiratory rate.
Non-invasive Ventilation Versus Sham Ventilation in Chronic Obstructive Pulmonary Disease (COPD)...
Hypercapnic Respiratory FailureChronic Obstructive Pulmonary DiseaseThe investigators hypothesize that continuation of non-invasive ventilation (NIV) at home after an episode of acute hypercapnic respiratory failure (AHRF) treated by NIV in COPD patients would reduce the likelihood of death and recurrent AHRF requiring NIV or intubation. The investigators designed this study in a way that recruited COPD patients would be started on home NIV or sham treatment after an episode of AHRF requiring acute NIV. The patients are acclimatised to NIV application after a few days of acute use. The investigators chose occurrence of life-threatening event (recurrent AHRF and death) as the primary endpoint.
Timing of Target Enteral Feeding in the Mechanically Ventilated Patient
Acute Respiratory FailureThis study tests the hypothesis that initial trophic enteral feedings will increase the time alive and free of mechanical ventilation as compared to initial goal enteral feedings in patients who are mechanically ventilated.
Prehospital CPAP vs. Usual Care for Acute Respiratory Failure
Respiratory InsufficiencyHypoxiaThe purpose of this study is to evaluate the effectiveness of continuous positive airway pressure ventilation when applied by paramedics to individuals with severe breathing difficulties in the prehospital setting.
Acetazolamide for Respiratory Failure in Combination With Metabolic Alkalosis
Respiratory InsufficiencyAlkalosisRespiratory failure is a common consequence of chronic obstructive pulmonary disease (COPD). A concurrent metabolic alkalosis may worsen the respiratory failure, as a higher pH in blood (and thus in cerebrospinal fluid) results in a weaker respiratory drive. Use of diuretics is the most common cause of metabolic alkalosis. When a patient with an acute exacerbation of a respiratory failure is also alkalotic, there are (at least theoretical) reasons to lower the pH in order to increase the respiratory drive. Among other alternatives, the drug acetazolamide can be used for this purpose. In some hospitals there is a tradition for the use of acetazolamide on this indication, but any evidence for the effect of such a treatment is rather weak. Thus, the aim of this trial is to evaluate the effect of acetazolamide as an adjuvant treatment for hospitalized patients with acute exacerbation of respiratory failure in combination with metabolic alkalosis.
Comparison of Humidified High Flow Nasal Cannula to Nasal CPAP in Neonates
Respiratory InsufficiencyWe hypothesize that the success rate for keeping babies extubated (without a breathing tube for assisted mechanical ventilation), defined as the proportion of infants remaining extubated for a minimum of 72 hours, will be equivalent among infants managed with nasal CPAP compared to humidified high flow nasal cannula (HHFNC).
Extracorporeal Support for Respiratory Insufficiency (ECMO)
Acute Respiratory FailureLung DiseasesTo evaluate indications for the use and efficacy of extracorporeal membrane oxygenators (ECMO's) for the support of patients with potentially reversible acute respiratory failure.
Oxygen Control and Weaning by O2matic to Patients Admitted With an Exacerbation of COPD
COPD ExacerbationHypoxia5 moreThe aim of the study is to examine if automated oxygen delivery with O2matic allows for faster weaning from oxygen and better oxygen control than manually controlled oxygen therapy for patients admitted with an exacerbation of chronic obstructive pulmonary disease (COPD). Furthermore it will be tested if O2matic compared to manual control allows for faster discharge from hospital. Patients sense of security, anxiety and dyspnea will be evaluated by questionnaires.
Novel Arm Restraint For Critically Ill Patients To Reduce Immobility, Sedation, Agitation and Cognitive...
Acute Respiratory FailureEncephalopathy3 moreThis study evaluates a novel arm restraint compared with traditional soft wrist restraints in older critically ill patients. The primary outcome is upper extremity mobility measured by actigraphy, and secondary outcomes include sedation, agitation, satisfaction, and acceptability.
