Reversal of Opioid-induced Respiratory Depression With Opioid Antagonists
Opioid Induced Respiratory DepressionChronic Opioid UseIn this pharmacokinetic/pharmacodynamic modelling study we will determine the ability of intranasal and intramuscular naloxone to reverse opioid (fentanyl and sufentanil)- induced respiratory depression in healthy volunteers and chronic opioid users to develop dosing recommendations in case of opioid-induced respiratory depression from an opioid overdose in clinical practice and in the out-of-hospital overdose.
Randomized Trial of Sedative Choice for Intubation
Acute Respiratory FailureAmong critically ill adults undergoing emergency tracheal intubation, one in five experience hypotension, cardiac arrest, or death. The sedatives used to rapidly induce anesthesia for emergency tracheal intubation have been hypothesized to effect cardiovascular complications and patient outcomes, but the optimal sedative medication for intubation of critically ill adults remains unknown. Ketamine and etomidate are the two most commonly used sedatives during intubation of critically ill adults. Data from a randomized clinical trial are urgently needed to determine the effect of ketamine versus etomidate on cardiovascular complications and clinical outcomes of emergency tracheal intubation.
Volume Mode Non-invasive Ventilation in Amyotrophic Lateral Sclerosis
Amyotrophic Lateral SclerosisRespiratory Failure7 moreThe purpose of this study is to assess the efficacy of using intelligent volume assured pressure support (iVAPS-AE) versus spontaneous timed (ST) modes of non-invasive ventilation (NIV) in patients diagnosed with amyotrophic lateral sclerosis (ALS). The investigators believe that the use of iVAPS-AE mode NIV over a 90 day period will produce NIV compliance data and health-related quality of life (HRQOL) scores that are equivalent or no worse compared to ST mode NIV.
ARrest RESpiraTory Failure From PNEUMONIA
PneumoniaHypoxemia2 moreThis research study seeks to establish the effectiveness of a combination of an inhaled corticosteroid and a beta agonist compared to placebo for the prevention of acute respiratory failure (ARF) in hospitalized patients with pneumonia and hypoxemia.
Safety and Efficacy of Argatroban Applicated in Anticoagulation of V-V ECMO
Respiratory FailureUnfractionated heparin is most common in the anticoagulation management of V-V ECMO. However, many side effects of unfractionated heparin, such as HIT, antithrombin deficiency, etc seriously affects the prognosis of patients. Argatroban is kind of direct thrombin inhibitors, which could be used used as an alternative anticoagulant of unfractionated heparin when HIT or antithrombin deficiency, etc. At present, there is no power enough evidence for the application of argatroban in V-V ECMO. This study aims to evaluat the safety and effectiveness of argatroban in the anticoagulation management of V-V ECMO compared with unfractionated heparin.
Non-invasive Respiratory Support in Preterm Infants
Preterm InfantRespiratory Insufficiency Syndrome of Newborn1 moreLungs of babies born early are not fully developed and they often need a machine to help them breathe. The traditional approach to provide this support is with a breathing tube passed into the windpipe. However, we know that breathing tubes can cause injury to the fragile lungs of premature babies. Providing breathing support through nose-masks instead of breathing tubes (called nasal breathing support) is becoming popular, as it is gentler on developing lungs. Doctors, in trying to limit the use of support with a breathing tube, are using many different forms of nasal breathing support. The most common form is nasal continuous positive airway pressure (CPAP) which delivers a constant pressure and the baby breathes on his on her own. However, when this strategy is no longer able to support a premature baby's breathing, the best way to provide breathing support is not known. Some doctors use a strategy called "nasal intermittent positive airway pressure" (NIPPV) which gives the baby artificial breaths through the nose-mask. Others simply increase the pressure on nasal CPAP to higher than traditional levels. In the first study of its kind, we will compare these two strategies of nasal breathing support given to premature babies.
Patient-ventilator Synchronisation Study for Intensive Care Unit Patients
Acute Respiratory FailureThis cross-over study will compare the asynchrony index between standard manual ventilator settings, optimized manual ventilator settings, and automated ventilator setting in intensive care patients ventilated in non-invasive ventilation with a high asynchrony index. The hypothesis is that both manual optimized ventilator settings and automated ventilator settings are associated with a lower patient-ventilator asynchrony index as compared to manual standard ventilator settings. A randomized cross-over design method will be used. Patient requiring NIV with an asynchrony index over 35% will be included. An esophageal catheter with a balloon will be inserted to monitor esophageal pressure. Patients will be ventilated during 3 periods of 30 min, with 10 minutes of washout in between. Recordings of airway pressure, airway flow, and esophageal pressure will be analyzed by two investigators blinded of the trigger settings. The primary outcome will be the asynchrony index. The secondary outcome will be the ineffective inspiratory effort index, autotrigering index, double triggering index, inspiratory trigger delay, cycling delay, total time spent in asynchrony, patient comfort, and blood gas results.
Different Modalities of Exercise Training in COPD With Chronic Respiratory Failure (CRF)
CopdChronic Hypoxemic Respiratory FailureAdvanced Chronic Obstructive Pulmonary Disease (COPD) is a condition with a negative prognosis that causes symptoms such as wheezing and fatigue that dramatically reduce the quality of life of the person with the disease. Typically, the advanced stage of COPD is characterized by a fluctuating pattern and recurrent hospitalizations, and by a vicious circle in which dyspnoea increases and exercise tolerance reduces, causing depression with social isolation, low quality of life and increased risk of death. Muscle dysfunction in these patients contributes together with dynamic hyperinflation to increased fatigue and dyspnoea during exercise, leading to early interruption of exertion, before reaching the maximal aerobic capacity. The European and American guidelines of the American Thoracic Society / European Respiratory Society relating to the patient with COPD emphasize the need for the patient to undergo Respiratory Rehabilitation (RR) programs. The RR should include training programs as they improve exercise capacity, dyspnoea and quality of life more than programs that do not include training. To our knowledge, no study has been performed in COPD with chronic respiratory failure (CRF) patients to evaluate the effects of High Interval Training compared to continuous submaximal training. Moreover, no different interval training protocols have been compared. However, studies conducted on healthy subjects or on other pathologies, show how the interval training protocol induces, in a specific and diversified way, physiological modifications to the cardio-respiratory and muscular systems. In COPD patients with respiratory failure with marked muscular dysfunction and associated systemic changes (systemic inflammation, vascular changes, pulmonary hypertension, right heart failure, etc.), the evaluation of the best training program would reinforce the rehabilitative indications not yet fully proposed in the Guidelines. Moreover, the evaluation of the response to different training stimuli could provide important information on the reversibility of the intolerance to the effort in this patient population. Primary aim of this study will be to evaluate the physiological effects on exercise tolerance of three training modalities performed in an intra-hospital setting (classic endurance training compared to two high-intensity interval programs - Long Interval Training and Short Interval training) in a population of COPD patients with chronic hypoxemic respiratory failure.
Strategies for Anticoagulation During Venovenous ECMO
Acute Hypoxemic Respiratory FailureAnticoagulant-induced Bleeding1 moreModerate intensity titrated dose anticoagulation has been used in patients receiving extracorporeal membrane oxygenation (ECMO) to prevent thromboembolism and thrombotic mechanical complications. As technology has improved, however, the incidence of thromboembolic events has decreased, leading to re-evaluation of the risks of anticoagulation, particularly during venovenous (V-V) ECMO. Recent data suggest that bleeding complications during V-V ECMO may be more strongly associated with mortality than thromboembolic complications, and case series have suggested that V-V ECMO can be safely performed without moderate or high intensity anticoagulation. At present, there is significant variability between institutions in the approach to anticoagulation during V-V ECMO. A definitive randomized controlled trial is needed to compare the effects of a low intensity fixed dose anticoagulation (low intensity) versus moderate intensity titrated dose anticoagulation (moderate intensity) on clinical outcomes during V-V ECMO. Before such a trial can be conducted, however, additional data are needed to inform the feasibility of the future trial.
Ganciclovir to Prevent Reactivation of Cytomegalovirus in Patients With Acute Respiratory Failure...
Acute Respiratory FailureThis is a phase 3 study designed to evaluate whether the administration of ganciclovir increases ventilator-free days in immunocompetent patients with sepsis associated acute respiratory failure. Our hypothesis is that IV ganciclovir administered early in critical illness will effectively suppress CMV reactivation in CMV seropositive adults with sepsis-associated acute respiratory failure thereby leading to improved clinical outcomes
