BACKGROUND: Bronchiolitis is a common respiratory illness of early childhood. For most children it is a mild self-limiting disease but a small number of children develop respiratory failure. Nasal continuous positive airway pressure (nCPAP) has traditionally been used to provide non-invasive respiratory support in these children, but there is little clinical trial evidence to support its use. More recently, high-flow nasal cannula therapy (HFNC) has emerged as a novel respiratory support modality...

BACKGROUND: The effects of high flow nasal cannula (HFNC) on adult patients with acute respiratory failure (ARF) are controversial. We aimed to further determine the effectiveness of HFNC in reducing the rate of endotracheal intubation in adult patients with ARF by comparison to noninvasive positive pressure ventilation (NIPPV) and conventional oxygen therapy (COT). METHODS: The Pubmed, Embase, Medline, Cochrane Central Register of Controlled Trials (CENTRAL) as well as the Information Sciences Institute (ISI) Web of Science were searched for all the controlled studies that compared HFNC with NIPPV and COT in adult patients having ARF...

After a planned extubation, the re-occurrence of acute respiratory distress needing the restoration of invasive mechanical support is a severe phenomenon associated with several important consequences, including increased morbidity, Intensive Care Unit mortality, and an enormous financial burden. So far, the most commonly used techniques to ameliorate gas exchange in the postextubation period were low-flow oxygen therapy and non-invasive ventilation (NIV). High flows through nasal cannulae (HFNC) is a system which allows increased CO2 wash-out of anatomical dead space, positive nasopharyngeal pressure, a relatively constant FiO2, and an improvement of mucociliary function...

The past decade has seen an exponential increase in the application and development of durable long-term as well as nondurable short-term mechanical circulatory support for cardiogenic shock and acute or chronic heart failure. Support has evolved from bridge-to-transplant to destination therapy, bridge to rescue, bridge to decision making, and bridge to a bridge. Notable trends include device miniaturization, minimally invasive and/or percutaneous insertion, and efforts to superimpose pulsatility on continuous flow...

Respiratory support using heated humidified high-flow nasal cannula (HFNC) therapy has become established practice over the past decade in neonatal intensive care units. HFNC therapy is delivered through small thin tapered cannulae that sit at the nasal aperture using oxygen, or blended oxygen and air, at flow rates greater than 1L/min(1, 2). Recently several studies have demonstrated that it can be safely used as a mode of respiratory support and that the positive end expiratory pressure generated is comparable to that delivered using continuous positive airway pressure (CPAP) (3-5)...

High-flow nasal cannula oxygen therapy (HFNC) is a technique for noninvasive ventilation commonly used in pediatric intensive care units for respiratory distress, particularly in acute bronchiolitis. HFNC was introduced in the pediatric emergency department of the Reims university hospital for the treatment of infants with moderate to severe acute viral bronchiolitis. This retrospective observational study aimed to investigate the use of HFNC in a pediatric emergency ward, describing the groups of infants with acute viral bronchiolitis to be treated either with conventional oxygen therapy or with HFNC therapy...

Background Common in children under two years, bronchiolitis is usually caused by respiratory syncytial virus (Jhawar 2003). Symptoms are usually self-limiting although some children develop respiratory distress requiring hospitalisation (Scottish Intercollegiate Guidelines Network 2006). Supplemental oxygen, fluid support and ventilator assistance may also be necessary. In cases of moderately severe bronchiolitis, oxygen can be delivered through a head box, but some hospitals deliver high-flow oxygen therapy with nasal prongs to treat respiratory distress...

Importance: Clinicians aim to extubate preterm infants as early as possible, to minimize the risks of mechanical ventilation. Extubation is often unsuccessful owing to lung disease or inadequate respiratory drive. Objective: To conduct a systematic review and meta-analysis of interventions to improve rates of successful extubation in preterm infants. Data Sources: Searches were undertaken in PubMed and The Cochrane Library. Study Selection: The review was conducted using the methods of the Cochrane Collaboration and Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines...

High flow oxygen therapy is characterized for its ability to meet or exceed the high peak inspiratory flow of the patients with acute respiratory failure. Despite the lack of definitive evidence regarding its efficacy in improving clinically significant outcomes, its application has been rapidly spreading over the last decade. In this review we discuss the potential physiologic mechanisms of benefit as well as the most recent clinical trials investigating its role in adult critically ill patient.

INTRODUCTION: Humidified oxygen via a high flow nasal cannula (HFNC) is a form of supplemental oxygen therapy that has significant theoretical advantages over conventional oxygen therapy (COT). However, the clinical role of HFNC in acute hypoxemic respiratory failure (AHRF) has not been well established. This review compares the efficacy of HFNC with COT and non-invasive ventilation (NIV) in patients with AHRF. METHODS: Studies reviewed were selected based on relevance from a systematic literature search conducted in Medline and EMBASE to include all published original research through May 2016...

BACKGROUND: High-flow nasal cannula therapy (HFNC) is widely used for patients with acute respiratory failure. HFNC has a number of physiological effects. Although FIO2 is considered to be constant, because HFNC is an open system, FIO2 varies according to inspiratory flow, tidal volume (VT), and HFNC gas flow. We investigated the influence of HFNC gas flow and other respiratory parameters on FIO2 during HFNC. METHODS: We evaluated an HFNC system and, for comparison, a conventional oxygen therapy system...

High-flow nasal cannula (HFNC) oxygen delivery has been gaining attention as an alternative means of respiratory support for critically ill patients, with recent studies suggesting equivalent outcomes when compared with other forms of oxygen therapy delivery. The main objective of this review was to extract current data about the efficacy of HFNC in critically ill subjects with or at risk for respiratory failure. We performed a systematic review of publications (from database inception to October 2015) that evaluated HFNC in critically ill subjects with or at risk for acute respiratory failure and performed a meta-analysis comparing HFNC with noninvasive ventilation (NIV) and with standard oxygen therapy regarding major outcomes: incidence of invasive mechanical ventilation and ICU mortality...

Targeting tumor angiogenesis is a potential therapeutic strategy for glioblastoma because of its high vascularization. Tivozanib is an oral pan-VEGF receptor tyrosine kinase inhibitor that hits a central pathway in glioblastoma angiogenesis. We conducted a phase II study to test the effectiveness of tivozanib in patients with recurrent glioblastoma. Ten adult patients were enrolled and treated with tivozanib 1.5 mg daily, 3 weeks on/1 week off in 28-day cycles. Brain MRI and blood biomarkers of angiogenesis were performed at baseline, within 24-72 h of treatment initiation, and monthly thereafter...
