Heated Humidified Oxygen Compared to Dry Oxygen Therapy in Children With Bronchiolitis
BronchiolitisHypoxemiaThe purpose of this study is to compare heat and humidified oxygen with cold and dry oxygen in children with bronchiolitis. The hypotheses are that heating and humidifying inspired low flow supplemental oxygen will optimize mucociliary function thereby, 1) improve oxygenation, 2) decrease work of breathing, and 3) decrease length of hospital stay.
7% Hypertonic Saline for Acute Bronchiolitis
Acute BronchiolitisResearch suggests that hypertonic saline may improve mucous flow in infants with acute bronchiolitis. Data suggest a trend favoring reduced length of hospital stay and improved pulmonary scores with increasing concentration of nebulized solution to 3% and 5% saline as compared to 0.9% saline mixed with epinephrine. To our knowledge, 7% hypertonic saline has not been previously investigated. OUr hypothesis was that 7% hypertonic saline would improve bronchiolitis severity scores and admission rate.
Suctioning of NOse Therapy in Bronchiolitis
BronchiolitisResearch Questions: Primary: In otherwise healthy infants 4 weeks to 12 months of age discharged home from the ED with acute bronchiolitis,1 is there a difference in the probability of "treatment failure" by 72 hours post discharge from the index ED visit in those receiving nasal suctioning via Zo-Li device prior to feeds compared to infants who receive nasal suctioning via bulb? Treatment failure is defined as 1) any bronchiolitis-related healthcare visit, except visits that have occurred only due to ED-recommendation at time of ED discharge or 2) the use of additional (non-study assigned) suctioning devices (see Outcome Measures section) within approximately 72 hours post discharge at the index ED visit. Hypothesis: We hypothesize that the infants who undergo scheduled nasal suctioning via ZoLi device will experience a lower treatment failure probability by approximately 72 hours post discharge from index ED visit compared to those managed by suction via a bulb. Secondary: In these infants, is there a difference in the mean number of medical visits for bronchiolitis (defined as #1 under primary outcome above) within 72 hours of ED discharge? In these infants, is there a difference in the mean number of unscheduled medical visits for bronchiolitis within 72 hours of ED discharge? In these infants, is there a difference in the mean number of ED visits for bronchiolitis within 72 hours of ED discharge? In these infants, is there a difference in the probability of a parent reporting normal/near normal feeds on approximately 72 hours discharge? In these infants, is there a difference in the probability of a parent reporting normal/near normal sleeping on approximately 72 hours post ED discharge? For the parent, is there a difference in the probability of a parent reporting their own normal/near normal sleeping on approximately 72 hours post ED discharge? In these infants, is there a difference in the probability of parents reporting at 72 hours post ED discharge as being "very satisfied" or "satisfied" with their ability to care for their child during the study period? The sample size calculation is based on the assessment of the between-group difference in probability of treatment failure. The estimated total re-visit probability in bronchiolitis based on a recently published study was approximately 35% within 72 hours of ED discharge.49 In our pilot we have found the same rate of treatment failure. This is a superiority study in which the adoption of nasal suctioning will be recommended for future practice if the observed proportion of the primary outcome in this group is significantly lower than in the controls. With 162 patients per arm (324 in total) a two-sided test with a type I error of 0.05 will have 80% power to achieve statistical significance if suctioning reduces the probability of treatment failure from 40% to 25% (i.e. absolute reduction of 15%). This estimate is based on clinically relevant differences agreed upon by study investigators and it also represents an NNT of 7. In the Cochrane review of asthma therapies an NNT of a comparable magnitude led to a change in national practice recommendations.51 Since bronchiolitis and related medical visits are highly prevalent,20 this target difference would also have an important economic impact. Based on our previous bronchiolitis trials, the anticipated refusal rate may be 20%. Given the study design and our past experience, the study non-completion rate and loss to follow-up can safely be assumed to be no higher than 5% each. Therefore, to have complete data on 324 patients we plan to randomize 360 (i.e. 324/ (1 - 0.05) *(1 - 0.05) and to approach 450 (i.e. 360/ (1 - 0.20).
Effect of Heliox on RSV Bronchiolitis
RSV InfectionAcute BronchiolitisHelium is an inert gas with a density almost one-seventh of that of air. Based on its properties breathing a mixture of helium and oxygen (heliox) will lead to a reduction in resistance through narrowed airways and consequently decreases the work of breathing. Participating infants with RSV acute bronchiolitis will be supplied with heliox (ration of 21 oxygen and 79 helium) delivered through a flow nasal cannula to evaluate heliox effect in improving their oxygenation. Heliox will act as an additive therapy to improve oxygenation in patients with lower respiratory tract infection caused by respiratory Syncytial Virus (RSV) and will decrease the need for more complicated therapies.
The Safety and Tolerability of Pirfenidone for BOS After HCT
Bronchiolitis ObliteransGraft Vs Host DiseaseThis is a phase 1, non-randomized, single-arm, open label, single center clinical trial to determine the tolerability and safety of pirfenidone in patients with BOS associated with lung GVHD after hematopoietic cell transplant.
Safety of Airway Clearance in Non-hospitalized Infants With Acute Viral Bronchiolitis
BronchiolitisBronchiolitis is a disease that can occur in a mild form and moderate, and often does not require hospitalization. The technique of prolonged slow expiration followed by cough caused in children not hospitalized with mild and moderate bronchiolitis can improve clinical severity
Chest Physiotherapy in Infants Between 0 and 12 Months Old With Acute Bronchiolitis SRV(+)
BronchiolitisViralThe purpose of this research is to determine the effect of prolonged slow expiration techniques, provoked coughing and standard therapy compared to chest wall manual vibration and standard therapy in infants between 0 and 12 months old with confirmed diagnosis of acute bronchiolitis SRV (+). The effect will be measured on respiratory insufficiency and use of supplementary oxygen.

Utility of Continuous Pulse Oximetry for Pediatric Patients With Stable Respiratory Illness
Respiratory DiseaseAsthma in Children2 moreThis is a randomized, prospective study to determine if there is a difference in hospital length of stay between patients receiving continuous hardwire cardiorespiratory monitoring and those receiving intermittent vital signs measurements among pediatric patients admitted for uncomplicated respiratory illness.
L-CsA in the Prevention of Bronchiolitis Obliterans Syndrome (BOS) in Lung Transplant (LT) Patients...
Bronchiolitis ObliteransImmunosuppression is a key intervention in patients with solid organ transplant and is usually achieved by combination therapy with systemic CsA or tacrolimus with azathioprine, mycophenolate mofetil (MMF), or corticoids. However, the outcomes after lung transplantation are poor when compared with those after heart, kidney, or liver transplantation, with a survival rate of only 55% for recipients of lung transplants. Additional application of aerosolised L-CsA should suppress T-cell activation in the lung tissue and subsequently BOS development. The overall purpose of this phase-II/III study is to obtain efficacy and safety data of L-CsA in the prevention of BOS.
