Difficulty in tracheal intubation in paediatric intensive care patients is associated with increased morbidity and mortality. Delays to intubation and interruption to oxygenation and ventilation are poorly tolerated. We developed a safe and atraumatic tracheal intubation technique. A floppy-tipped guidewire and airway exchange catheter were placed to a pre-determined length under bronchoscopic guidance while oxygenation and ventilation was maintained via a supraglottic airway device (SAD). We performed a retrospective review of this technique on patients who were either known to have or who had an unexpected difficultly in intubation...

BACKGROUND AND OBJECTIVES: The laryngeal mask airway (LMA) ProSeal is most commonly used supraglottic airway device; it is routinely inserted by blind technique. Although blind insertion technique is most widely used, there are many techniques which are available such as priming the drain tube with a guiding instrument such as a suction catheter, a gum elastic bougie, a Flexi-Slip Stylet, direct laryngoscopy, and even a fiber-optic bronchoscope (FOB). The present study was undertaken to compare and assess the placement of LMA ProSeal using blind versus direct laryngoscopy techniques using FOB...

BACKGROUND: We evaluated the incidence, clinical effect, and recovery rate of vocal cord dysfunction (VCD) and swallowing dysfunction in neonates undergoing aortic arch repair. METHODS: We retrospectively evaluated 101 neonates who underwent aortic arch reconstruction from 2008 to 2015. Direct flexible laryngoscopy was performed in 89 patients before initiation of postoperative oral feeding after Norwood (n = 63) and non-Norwood (n = 26) arch reconstruction. We defined VCD as immobility of vocal cords or their lack of coaptation and poor mobility...

A 23-year-old woman presented to the emergency department (ED) with a sensation of a 'fish bone' stuck in her throat after eating cod. On physical examination, while she reported an uncomfortable sensation in her throat, no airway compromise was evident. Clinical examination, including ear, nose and throat (ENT) and oropharyngeal assessment, was unremarkable. A linear opacity consistent with a fishbone was visualised on a soft tissue lateral neck X-ray anterior to the vertebral body of C4-6. One attempt to visualise the fishbone on direct laryngoscopy failed in the ED...

BACKGROUND: Laryngopharyngeal reflux (LPR) refers to the flow of gastric acid content into the laryngopharynx. It has been reported that 10% of the patients consulting an otolaryngologist present with this condition. Signs of LPR can be identified during flexible or rigid laryngoscopy. The Voice Handicap Index (VHI) is a reliable tool for detecting the impact of voice disorders, and acoustic assessment of voice including acoustic analysis of voice (AAV) and electroglottography (EGG) provide objective data of voice production and voice disorders...

This is a rare presentation of a morbidly obese male with a massive retropharyngeal goiter causing laryngeal compressive symptoms and unique airway management challenges. Flexible laryngoscopy revealed a retropharyngeal mass circumferentially compressing the oropharynx and supraglottis and preventing the visualization of the glottis. Awake tracheostomy was performed before total thyroidectomy. Airway compression from a goiter typically results from substernal extension, which usually does not cause difficulty with endotracheal intubation...

Cricoarytenoid joint subluxation is rare condition. There are <200 cases reported in the English literature. The most frequent cause of this condition is a traumatic tracheal intubation which account for approximately 80 % of all cases. The most common symptoms are dysphonia and pain of the anterior region of the neck which appear after upper airway manipulation or cervical trauma. In this report we present a well-documented case of a 31 year old male that was referred to the outpatient clinic because of acute dysphonia and pain that appeared immediately after receiving a blow of a soccer ball...

BACKGROUND AND AIMS: The difficulty during flexible fiber-optic bronchoscopy (FOB) guided tracheal intubation could be because of inability in visualising glottis, advancing and railroading of endotracheal tube. Several methods are available for visualising glottis, but none is ideal. Hence, this randomised controlled study was designed to evaluate the simple pre-determined length insertion technique (SPLIT) during oral FOB. METHODS: Fifty-eight patients were randomised into Group C and Group P...

BACKGROUND: Many emergency physicians gain familiarity with the laryngeal anatomy only during the brief view achieved during rapid sequence induction and intubation. Awake laryngoscopy in the emergency department (ED) is an important and clinically underutilized procedure. DISCUSSION: Providing benefit to the emergency physician through a slow, controlled, and deliberate examination of the airway, awake laryngoscopy facilitates confidence in the high-risk airway and eases the evolution to intubation, should it be required...

A 23-day-old infant referred to the neonatal intensive care unit with difficulty breathing and inspiratory stridor increasing with exercise. Medical history included a cardiothoracic surgery for transposition of the great arteries, patent ductus arteriosus, atrial septal defect, and a history of intensive care unit from surgery. Flexible fiberoptic transnasal laryngoscopy revealed subglottic stenosis that was probably caused by prolonged intubation with a higher airway pressure. Computed tomographic scan of the neck showed a tiny stenosis without cartilage deformity and limited in subglottic region...

REVIEW
Jana Lohse, Rüdiger Noppens
INTRODUCTION: Awake video laryngoscopy is a novel option in airway management that is drawing more and more attention as an alternative to awake endoscopic guided intubation.Main issues: Intubation under preserved spontaneous breathing is the safest method to secure the expected difficult airway. In direct comparisons to awake flexible endoscopic intubation, awake video laryngoscopy achieves satisfactory intubation times and a high acceptance of patients and anesthesiologists. Specific cases, in particular very limited mouth opening or sub-glottic masses, require awake flexible endoscopic intubation...
