Arteriovenous (AV) malformations of the face are rare presentations. Endovascular coiling is one of the treatment modalities. We report a case of a 65-year-old lady who presented with a large AV malformation of the face located around the nasal bride and alae nasae posted for coiling under general anesthesia. Anesthetic management of the case was a challenge as it was an anticipated difficult airway situation. Furthermore, any pressure on the swelling can lead to rupture and hemorrhage as the skin above swelling was unhealthy...

BACKGROUND: Prehospital airway management increasingly involves supraglottic airway insertion and a paucity of data evaluates outcomes in trauma populations. We aim to describe definitive airway management in traumatically injured patients who necessitated prehospital supraglottic airway insertion. METHODS: We performed a single institution retrospective review of multisystem injured patients (≥15years) that received prehospital supraglottic airway insertion during 2009 to 2016...

BACKGROUND: The forced oscillation technique (FOT) is a non-invasive means of measuring respiratory resistance and reactance. We tested our hypothesis that endotracheal intubation would cause more substantial preoperative increases in FOT parameters than a supraglottic airway device (SGD). METHODS: Forty patients requiring general anesthesia and mechanical ventilation for transurethral bladder tumor resection underwent spirometry the day before surgery. Forced oscillation was measured using a MostGraph-01 device the day before surgery and immediately after removal of the airway adjunct...

OBJECTIVE AND HYPOTHESIS: Vocal effort in loud voice is produced with increased subglottal pressure during vowels and increased supraglottal pressure during consonants. In the paper, our main objective is to check whether it was supported by a parallel increase in the airflow resistance of the laryngeal articulator and of the supralaryngeal articulator, here the lips. STUDY DESIGN AND METHOD: For this comparison, our choice fell on the fricative consonants, as their production allows perfectly synchronous air pressure and airflow measurements...

BACKGROUND: Although human and equipment resources, proper training, and the verification of endotracheal intubation are vital elements of difficult airway management (DAM), their availability in Japanese emergency departments (EDs) has not been determined. How ED type and patient volume affect DAM preparation is also unclear. We conducted the present survey to address this knowledge gaps. METHODS: This nationwide cross-sectional study was conducted from April to September 2016...

The laryngeal mask airway (LMA) Protector™ is a second-generation perilaryngeal sealer type supraglottic airway device recently introduced into clinical practice. We describe our initial experiences with the use of the LMA Protector™ in three patients undergoing laparoscopic cholecystectomies. In all patients, we found the LMA Protector™ to have acceptable placements on the first attempt, adequate oropharyngeal leak pressures and ventilation adequacy.

BACKGROUND: The most important adverse prognostic factor for laryngeal squamous cell carcinoma (LSCC) is the presence of cervical lymph node metastases. The supraglottic area of the larynx is richly supplied with lymphatics, and 25%-75% of supraglottic carcinomas metastasize in neck lymph nodes. Cortactin is a multidomain protein related to actin cytoskeleton regulation, podosome and lamellipodia formation, integrin signaling, axon guidance and extracellular matrix degradation. Cortactin is involved in metastasis formation because of its role in cell mobility...

BACKGROUND: An obstructive neck lesion presents an airway challenge for any emergency physician. Retrograde intubation is an infrequently used airway alternative that can be employed in the difficult airway algorithm that requires little training and is less invasive than surgical cricothyrotomy. CASE REPORT: We report a case of a 31-year-old male patient who presented with respiratory distress progressing to respiratory failure from upper airway obstruction. The patient had significant tracheal thickening at the level of the thyroid gland based on a computed tomography report from 3 weeks prior to his presentation...

BACKGROUND: Fiberoptic bronchoscope-guided tracheal intubation is the gold standard for managing patients with supraglottic growths. In infants with a large and overhanging epiglottis, the success of fiberoptic-guided intubation relies heavily on the available space between the inferior surface of the epiglottis and the posterior pharyngeal wall or, more specifically, the superior surface of the supraglottic growth. CASE REPORT: We describe the inability to negotiate the tip of the fiberscope between the epiglottis and the supraglottic growth and the successful use of direct laryngoscopy to improve the available space along with the usefulness of "bubbling of air" to locate the glottic opening in an infant...

BACKGROUND: Supraglottic airway devices (SGA) are commonly used in pediatric anesthesia and serve as primary or back-up devices for difficult airway management. Most SGA are marketed without proper clinical evaluation. The purpose of this study was to evaluate the performance of the pediatric LMA Supreme™, Air-Q® and Ambu® Aura-i™. METHODS: This prospective observational study was performed at Bern University Hospital, Switzerland. With ethics committee approval and a waiver for written informed consent 240 children undergoing elective surgery with an ASA class I-III and a weight of 5-30 kg were included...

Purpose: Our goal was to test prevailing assumptions about the underlying biomechanical and aeroacoustic mechanisms associated with phonotraumatic lesions of the vocal folds using a numerical lumped-element model of voice production. Method: A numerical model with a triangular glottis, posterior glottal opening, and arytenoid posturing is proposed. Normal voice is altered by introducing various prephonatory configurations. Potential compensatory mechanisms (increased subglottal pressure, muscle activation, and supraglottal constriction) are adjusted to restore an acoustic target output through a control loop that mimics a simplified version of auditory feedback...

OBJECTIVE: Flexible nasolaryngoscopy (FNL) is considered the gold standard for evaluation of vocal fold mobility but there has been no data on the reliability of interpretation in the infant population. Visualization may be limited by excessive movement, secretions, or floppy supraglottic structures that prevent accurate diagnosis of vocal fold movement impairment (VFMI). We sought to evaluate the inter- and intra-rater reliability of FNL for the evaluation of VFMI in young infants. STUDY TYPE: Case-control...
