Active clinical trials for "Bronchiolitis, Viral"

This aim of this study is to measure the peak tidal inspiratory flow (PTIF), using spirometry, in young infants with moderate to severe acute viral bronchiolitis (AVB). PTIF is important to consider for the management of AVB with High Flow Nasal Cannulae (HFNC). Indeed, efficiency with HFNC is optimal provided that the settled flow is equal or higher than the patient's PTIF. However, PTIF values in infants with AVB have never been determined.

This study will compare the novel methods of NS and BS with the standard technique of nasophayngeal aspiration (NPA) and routine ETT suction. We shall assess the samples for diagnosis of RSV, viral load and immune responses in the airways of babies with RSV infection. We shall also assess the genetics of babies included in this study, to see if they may be vulnerable to RSV infection.

This exploratory intervention feasibility study aims to evaluate the use of a novel mode of ventilation known as Neurally adjusted ventilatory assist (NAVA) in infants with acute viral bronchiolitis. The main aims are: To determine whether an optimal combination of NAVA support level and Positive End Expiratory Pressure (PEEP) exists that can: maximise aspects of respiratory muscle unloading and minimize air trapping To evaluate the impact of two morphine infusion doses on comfort levels and respiratory drive (standard = 20mcg/kg/hr, low = 5mcg/kg/hr) during ventilation titration. Patients will act as their own control and will be randomly allocated to receive either standard or low dose morphine. They will receive the alternate dose on day 2. During each period of morphine dosing ventilation levels will be titrated and vital signs, respiratory parameters and comfort b scales will be recorded.

Background: acute bronchiolitis (AB) is a common reason for hospitalization of infants in all population groups, and is usually due to respiratory syncytial virus (RSV) infection. The main cause for hospitalization is often a need for oxygen, but can also include high fever (with a suspected secondary bacterial infection) or increasing respiratory distress. In a minority of cases (some of which can be identified in advance by defining risk groups) a serious illness may develop, including risk of respiratory failure and death. Most cases will just require supplemental oxygen and suction of secretions from the nose (as listed in the recommendations of the American Academy of Pediatrics - AAP). However, this apparently "simple" treatment still requires continued hospitalization. This results in a sharp increase in bed occupancy in Israeli hospital pediatric departments in the winter months. In recent years two studies from developed countries have been published where safety has been demonstrated for home oxygen treatment for babies with AB. However, feasibility studies have not been published yet, for example for populations living in poor conditions. The General Health Services (Klalit) in Israel provides integrated hospital and community health service to the majority of the population living o in our region, thus presenting an opportunity for optimal interventions related to this disease.

This study is designed to assess the effectiveness of nasal continuous positive airway pressure in reducing respiratory distress in children with bronchiolitis

Acute viral bronchiolitis is the principal cause of lower respiratory tract infection in infants worldwide. It is characterized by a first episode of respiratory distress preceded by rhinorrhea, cough and fever. The majority of patients present with mild symptoms which can be treated safely at home by parents. Every year between October thru April emergency departments in North America are overwhelmed with patients waiting to be seen with mild respiratory infections, such as bronchiolitis. Thus new strategies in health care have to be elaborated to reduce costs and waiting time in the emergency department. The investigators hypothesize that patients liberated from triage with mild acute viral bronchiolitis would have the same rate of office re-visits than those with mild acute bronchiolitis in the emergency department.

The aim of the investigators study is to compare in children aged less than 18 months and hospitalized for an acute viral bronchiolitis the efficacy of the HS 3% (Mucoclear®, sterile ampoules of 4 ml) nebulised with a conventional jet-nebulizer (particles diameter of 4-5 µm), or with a jet-nebulizer adapted for infants (particles diameter of 2-2.5 µm), or with a mesh-nebulizer adapted for infants (particles diameter of 2-2.5 µm).

Serum KL-6 protein has been described as a biomarker of epithelial lung injury in Respiratory Syncytial Virus bronchiolitis. The investigators can imagine that epithelial injury intensity has consequences on immediate and later respiratory prognosis. Furthermore, this prognosis seems to be different according to the respiratory causative virus. The investigators propose to study, during an epidemic season, the correlation between KL-6 levels and clinical severity, and the type of viral infection.

Acute viral bronchiolitis is the leading cause of community-acquired acute respiratory failure in developed countries (20 000 to 30 000 hospitalizations each year in France). Between 5% and 22% of these children are hospitalized in a critical care unit to benefit from a respiratory support. Non-invasive ventilation, in particular the nasal Continuous Positive Airway Pressure (nCPAP), reduces the work of breathing in children with bronchiolitis and is associated with decreased morbidity and hospitalization costs compared with invasive ventilation. Nowadays, this technique is considered as the gold standard in the pediatric intensive care units (PICU) in France. High Flow Nasal Cannula (HFNC) has been proposed as an alternative to the nCPAP because of its better tolerance and simplicity of implementation. However, the proportion of failure remains high (35 to 50%), providing only a partial response to the care of these children, especially prior to the PICU. In a physiological study (NCT02602678, article published), it has been demonstrated that prone position (PP) decrease, by almost 50%, the respiratory work of breathing and improve the respiratory mechanics in infants hospitalized in intensive care units for bronchiolitis. Investigators hypothesize that prone position, during High Flow Nasal Cannula (HFNC), would significantly reduce the use of non-invasive ventilation (nCPAP and others) or invasive ventilation, as compared to supine position during HFNC, in infants with moderate to severe viral bronchiolitis.
