PURPOSE: Despite the recent CREST trial demonstrating a survival benefit to thoracic radiotherapy (TRT) for patients with extensive-stage small-cell lung cancer (ES-SCLC) with response to chemotherapy, as well as endorsement by current National Comprehensive Cancer Network guidelines, TRT may not be uniformly delivered in clinical practice across all circumstances. METHODS AND MATERIALS: We surveyed US academic thoracic radiation oncologists regarding their practice patterns for TRT and assessed conditions in which withholding TRT could be warranted...

OBJECTIVE: Feeding neonates orally while on nasal continuous positive airway pressure (nCPAP) is a common practice. We hypothesize that pressurized airflow provided by nCPAP will alter the swallowing mechanism in neonates, increasing the risk of aspiration during oral feeding. STUDY DESIGN: Infants receiving nCPAP with a RAM cannula and tolerating at least 50% of their feeding orally were included in the study (one term; six preterm infants). Each participant underwent a videofluoroscopic swallow study while on nCPAP and off nCPAP...

OBJECTIVES: To compare extubation failure rate between the heated humidified high-flow nasal cannula (HHHFNC) and continuous positive airway pressure (CPAP) groups. METHODS: Intubated infants with gestational age (GA) <32 wk, who were ready to extubate, were randomized to receive respiratory support with either CPAP or HHHFNC after extubation. In CPAP group, nasal mask CPAP with preset pressure and fraction of inspired oxygen (FiO2) equal to positive end-expiratory pressure (PEEP) and FiO2 of ventilator before extubation was applied...

Transient receptor potential ankyrin 1 (TRPA1), a member of the TRP superfamily, exists in sensory neurons such as trigeminal neurons innervating the nasal cavity and vagal neurons innervating the trachea and the lung. Although TRPA1 has been proposed as an irritant receptor that, when stimulated, triggers bradypnea, precise locations of the receptors responsible have not been elucidated. Here, we examined the relative importance of TRPA1 located in the upper airway (nasal) and the lower airway (trachea/lungs) in urethane-anesthetized mice...

BACKGROUND: The nose is a dangerous site for filler injection. This study investigated the anatomy of the dorsal nasal artery at the upper part of the nose to clarify how ocular complications occur. METHODS: Dissections were performed in 50 noses of the embalmed cadavers. Either the soft embalming or formaldehyde embalming processes were used. RESULTS: The dorsal nasal artery is not a constant artery. The artery traveled in the subcutaneous tissue layer of the nasal dorsum on the transverse nasalis muscle and its midline nasal aponeurosis which connected the muscles on both sides...

BACKGROUND: Recovering premature infants are at risk for hypoxemia and lack of synchrony between their rib cage and abdomen due to airflow obstruction and poor respiratory compliance. Thoracoabdominal asynchrony (TAA) is a useful marker of resistive and elastic lung properties. Whether TAA predicts oxygenation is unknown. OBJECTIVES: We investigated oxyhemoglobin saturation (SpO2%) and TAA (phase angle, φ) in preterm infants with/without high-humidity nasal cannula (HHNC)...

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...

Tracheal intubation (TI) is a routine procedure in the Intensive Care Unit (ICU) and is often life-saving. In contrast to the controlled conditions in the operating room, critically ill patients with respiratory failure and shock are physiologically unstable. These factors, along with a suboptimal evaluation of the airway and limited oxygen reserves despite adequate pre-oxygenation, are responsible for a high incidence of life-threatening complications such as severe hypoxaemia and cardiovascular collapse during TI in the ICU...

BACKGROUND: Accurately measuring the partial pressure of end-tidal CO2 (PETCO2 ) in non-intubated patients is problematic due to dilution of expired CO2 at high O2 flows and mask designs that may either cause CO2 rebreathing or inadequately capture expired CO2. We evaluated the performance of 2 capnographic O2 masks (Cap-ONE and OxyMask) against a clinically expedient method using a standard O2 mask with a flow-directed nasal cannula used for capnography (CapnoLine) in a spontaneous breathing model of an adult and child under conditions of normal ventilation, hypoventilation, and hyperventilation...

BACKGROUND: Partial pressure of end-tidal carbon dioxide (PETCO2 ) monitoring in children is important to detect apnea or hypopnea early to intervene before hypoxemia develops. Monitoring PETCO2 in children without a tracheal tube is challenging. To improve PETCO2 measurement accuracy in a commercially available mask with a mainstream CO2 detector, we implemented design changes with deform-and-hold shaping technology and anterior-posterior adjustment of the expiratory gas flow cup. METHODS: Two sizes of redesigned face masks (small for 7-20 kg, medium for 10-40 kg) were evaluated...

Hypoxemia is a complication of pneumonia-the leading infectious cause of death in children worldwide. Treatment generally requires oxygen-enriched air, but access in low-resource settings is expensive and unreliable. We explored use of reservoir cannulas (RCs), which yield oxygen savings in adults but have not been examined in children. Toddler, small child, and adolescent breathing profiles were simulated with artificial lung and airway models. An oxygen concentrator provided flow rates of 0 to 5 L/min via a standard nasal cannula (NC) or RC, and delivered oxygen fraction (FdO2) was measured...

BACKGROUND: Granulocyte-colony stimulating factor (G-CSF) is widely used to mobilize peripheral blood stem cells (PBSCs) in healthy donors. A few reports have shown that some healthy donors developed acute respiratory distress syndrome or capillary leak syndrome after more than several rounds of G-CSF administration or leukapheresis. CASE REPORT: We report the case of a healthy donor for allogeneic stem cell transplantation who developed severe hypoxemia 1 h after only the first administration of G-CSF...

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...

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...

BACKGROUND: Capnometry detects hypoventilation earlier than pulse oximetry while supplemental oxygen is being administered. We compared the end-tidal CO2 (PETCO2 ) measured using a newly developed oxygen nasal cannula with a CO2-sampling port and the PaCO2 in extubated subjects after abdominal surgery. We also investigated whether the difference between PaCO2 and PETCO2 is affected by resting, by spontaneous breathing with the mouth consciously closed, and by deep breathing with the mouth closed...
