BACKGROUND: A high burden of lower airway symptoms is found in elite swimmers. To what extent elite swimmers suffer from upper airway symptoms and how these associate with nasal inflammation is less clear. We here aimed to evaluate upper airway symptoms and nasal inflammation in elite athletes. METHODOLOGY: Elite swimmers, indoor athletes and age-matched controls were recruited. Upper airway symptoms were assessed by sino-nasal outcome test (SNOT)-22 questionnaire...

AIMS: To investigate whether nasopharyngeal airway (NPA) intubation could reduce the risk of complications caused by radiofrequency thermocoagulation (RFT) of the trigeminal ganglion. METHODS: From November 1, 2014 to May 1, 2015, 200 patients treated with sedation (combination of sufentanil and propofol) were randomly divided into two groups, one in which NPA intubation was used (intervention group) and one in which it was not used (control group). The primary outcome was the frequency of hypoxemia, and secondary outcomes were the frequency of hypotension, nasal mucosa damage, corneal numbness, masticatory weakness, palsies of other cranial nerves, and intracranial hemorrhage...

BACKGROUND: Air pollution exposure may contribute to rhinoconjunctivitis morbidity in children with underlying airways disease. Prior studies have not assessed rhinoconjunctivitis-related quality of life (QOL) in children with asthma chronically exposed to air pollution. METHODS: Children ages 9-19 years with asthma from peri-urban Peru, self-reporting rhinoconjunctivitis symptoms (n = 484), were administered the Rhinoconjunctivitis QOL Questionnaire (RQLQ) at repeated intervals over one year, with scores dichotomized into bothered (>0) and not bothered (= 0)...

Nanoparticles (NP)-based inhalation systems for drug delivery can be administered in liquid form, by nebulization or using pressurized metered dose inhalers, and in solid form by means of dry powder inhalers. However, NP delivery to the lungs has many challenges including the formulation instability due to particle-particle interactions and subsequent aggregation, causing poor deposition in the small distal airways and subsequent alveolar macrophages activity, which could lead to inflammation. This work aims at providing an in vitro experimental design for investigating the correlation between the physico-chemical properties of NP, and their biological behavior, when they are used as NP-based inhalation treatments, comparing two different exposure systems...

OBJECTIVE: To evaluate the feasibility/effectiveness of using magnetic resonance imaging (MRI) to document velopharyngeal (VP) structural changes induced by continuous positive airway pressure (CPAP) therapy. OUTCOME MEASURES: Changes in velar length and thickness, levator veli palatini (LVP) length and thickness, velar volume, and intravelar muscular proportion along the course of CPAP therapy participation (Pre-CPAP, Post-CPAP, and withdrawal). RESULTS: Velar and LVP lengths remained nearly the same, with the median changes (Δ) less than 0...

PURPOSE: To evaluate submental intubation compared with secure airways of patients who have sustained significant maxillofacial trauma. PATIENTS AND METHODS: Patient series of 3 patients who underwent submental intubation prior to open reduction internal fixation of fractures associated with the mid and lower face. All of these patients were initially orally intubated, and then converted to submental intubation prior to the reparative procedure. Detailed description of the procedure is discussed in each patient...

INTRODUCTION: Combined mid-face and nasal apparatus trauma injuries pose a significant challenge to airway patency (AW), in the immediate postoperative setting following fracture reduction. As such, the authors describe a modified technique with the goal of maintaining a patent nasal AW, while at the same time, minimizing nasopharyngeal bleeding and nasal AW edema-which can complicate patients requiring intermaxillary fixation (IMF) in the setting of pan-facial trauma. METHODS: A modified technique was devised to assist the reconstruction surgeon in avoiding the risks associated with tracheostomy placement...

Negative pressure pulmonary edema is a well-described complication of upper airway obstruction. However, the simultaneous occurrence of blood-stained secretions and petechial tracheobronchial hemorrhage are rarely recognized and a potential complication of transient intentional occlusion of the airways. We described a case of "hemorrhagic bronchial mucosa syndrome" and asymptomatic blood-tinged pulmonary edema after balloon bronchoplasty for a concentric tracheal stenosis using a flexible bronchoscopy...

PURPOSE OF REVIEW: Cardiac arrest mortality remains high, and the impact on outcome of most advanced life support interventions is unclear. The optimal method for managing the airway during cardiac arrest remains unknown. This review will summarize and critique recently published evidence comparing basic airway management with the use of more advanced airway interventions [insertion of supraglottic airway (SGA) devices and tracheal intubation]. RECENT FINDINGS: Systematic reviews generally document an association between advanced airway management and worse neurological outcome but they are subject to considerable bias...

Introduction: A benefit of in-hospital cardiac arrest is the opportunity for rapid initiation of "high-quality" chest compressions as defined by current American Heart Association (AHA) adult guidelines as a depth 2-2.4 inches, full chest recoil, rate 100-120 per minute, and minimal interruptions with a chest compression fraction (CCF) ≥ 60%. The goal of this study was to assess the effect of audiovisual feedback on the ability to maintain high-quality chest compressions as per 2015 updated guidelines...

Introduction: Procedural sedation and analgesia (PSA) is used by non-anesthesiologists (NAs) outside of the operating room for several types of procedures. Adverse events during pediatric PSA that pose the most risk to patient safety involve airway compromise. Higher Mallampati scores may indirectly indicate children at risk for airway compromise. Medical governing bodies have proposed guidelines for PSA performed by NAs, but these recommendations rarely suggest using Mallampati scores in pre-PSA evaluations...

Patients requiring emergency airway management may be at greater risk of acute hypoxemic events because of underlying lung pathology, high metabolic demands, insufficient respiratory drive, obesity, or the inability to protect their airway against aspiration. Emergency tracheal intubation is often required before complete information needed to assess the risk of procedural hypoxia is acquired (i.e., arterial blood gas level, hemoglobin value, or chest radiograph). During pre-oxygenation, administering high-flow nasal oxygen in addition to a non-rebreather face mask can significantly boost the effective inspired oxygen...

The fluid transport and mixing induced by beating cilia, present in the bronchial airways, are studied using a coupled lattice Boltzmann-Immersed Boundary solver. This solver allows the simulation of both single and multi-component fluid flows around moving solid boundaries. The cilia are modeled by a set of Lagrangian points, and Immersed Boundary forces are computed onto these points in order to ensure the no-slip velocity conditions between the cilia and the fluids. The cilia are immersed in a two-layer environment: the periciliary layer (PCL) and the mucus above it...

The C-MAC videolaryngoscope was evaluated for intubation in patients with predicted extremely difficult airway. The presented cases are patients with neoplasm tumors in larynx. In all cases, awake intubation using C-MAC videolaryngoscope was performed in patients breathing spontaneously, under local anaesthesia, with oxygen administered via nasal catheter. All intubations were successful and uneventful. The pre-surgery examination (CT scans and fiberscope laryngeal examination) was compared with view of larynx obtained during laryngoscopy...

BACKGROUND: The American Academy of Pediatrics Section on Transport recommends the use of portable ventilators during the transport of patients with advanced airways. We sought to identify knowledge gaps and evaluate the effectiveness of a transport ventilator competency boot camp. METHODS: Electronic health records of children requiring ventilatory support during air and ground interfacility transport from January 1 through December 31, 2015, were reviewed to determine when manual ventilation was used in lieu of a portable ventilator, and simulations were constructed from commonly occurring scenarios...

BACKGROUND: We sought to compare treatment satisfaction with inhaled medications among asthmatics using a metered-dose inhaler (MDI) or a dry-powder inhaler (DPI), and to correlate satisfaction with treatment adherence, pulmonary function, and airway inflammation. METHODS: Spirometry, fraction of expired nitric oxide (FENO ), and asthma control were assessed in 200 adult subjects with asthma (69 men, 131 women) using MDI or DPI. Treatment satisfaction with inhaled therapy was assessed with the Treatment Satisfaction Questionnaire for Medication (TSQM) in 4 domains: Effectiveness, Side Effects, Convenience, and Global Satisfaction...
