OBJECTIVE: Airway management in patients with suspected cervical spine injury is classified as a "difficult airway." The best device for managing difficult airways is not known. Therefore, we conducted an intubation study simulating patients with cervical spine injury using three devices: a conventional Macintosh laryngoscope, a video laryngoscope (GlideScope), and a fiberoptic bronchoscope (MAF-TM). Success rates, intubation time, and complication rates were compared. METHODS: Nine physician experts in airway management participated in this study...

BACKGROUND: It has been suggested that an adult 8.0 endotracheal tube (ETT) connected to a neonatal meconium aspirator would improve suctioning during emergent endotracheal intubation compared to the Yankauer suction instrument, the standard tool used by emergency physicians. OBJECTIVES: This study was designed to compare the effectiveness of a Yankauer vs. an ETT-meconium aspirator set-up in suctioning liquids of different viscosities. METHODS: The Yankauer and ETT-meconium aspirator device underwent a head-to-head timed comparison, suctioning 250 mL of three different fluids, varying in viscosity...

Tongue entrapments within bottles are very rare childhood mishaps. The most immediate hazard in a tongue entrapment is airway obstruction. Tongue entrapment is an airway emergency; contingency planning to maintain airway patency, oxygenation, and ventilation is critical. Here, we report the case of a 5-year-old girl presenting to a pediatric emergency department with an increasingly popular novelty soda bottle, featuring a unique and dangerous design, entrapped on her tongue. Operative removal was anticipated...

BACKGROUND: Fiberoptic intubation is a technique commonly used for difficult airways. Conscious sedation is desirable to make this procedure tolerable, and it is essential that patients are cooperative, relaxed, and comfortable especially when difficult airway anatomy or pathology is encountered. OBJECTIVE: To compare the safety and efficacy of propofol versus midazolam in oral fiberoptic endotracheal intubation in terms of hemodynamic changes, level of sedation, ease of intubation, and patient comfort and complications...

We hypothesized that the McGRATH MAC would decrease the time of intubation compared to C-MAC for novices. Thirty-nine medical students who had used the Macintosh blade to intubate a manikin fewer than 3 times were recruited. The participants performed sequential intubations on the manikin in two simulated settings that included a normal airway and a difficult airway (tongue edema). The intubation time, success rate of intubation, Cormack-Lehane grade at laryngoscopy, and difficulty using the device were recorded...

INTRODUCTION: Difficult airway management is associated with an increased risk of morbidity and mortality. Several preoperative risk factors associated with airway management difficulties have been proposed; however, no clear guideline for airway assessments exists. We therefore hypothesised that Danish airway assessment was lacking uniformity. We aimed to examine whether multivariable risk assessment tools and predictors for difficult intubation and mask ventilation were used systematically...

BACKGROUND: Single-use plastic blades (SUPB) and single-use metal blades (SUMB) for direct laryngoscopy and tracheal intubation have not yet been compared with reusable metal blades (RUMB) in difficult airway scenarios. OBJECTIVE: The purpose of our manikin study was to compare the effectiveness of these different laryngoscope blades in a difficult airway scenario, as well as in a difficult airway scenario with simulated severe inhalation injury. METHODS: Thirty anesthetists performed tracheal intubation (TI) with each of the three laryngoscope blades in the two scenario manikins...

Laryngeal cysts are largely asymptomatic and typically described in the context of incidental discovery on routine laryngoscopy. These cysts, in adults are even rarer and can have catastrophic consequences in an anaesthetized patient if airway management is inappropriate. We describe a case of difficult endotracheal intubation and the treatment of an adult patient with an asymptomatic, giant vallecular cyst that was discovered during rapid-sequence induction of general anesthesia in urgent surgery. In conclusion, vallecular cysts can cause extreme problems in securing the airway...

PURPOSE: Two types of bradykinin-mediated angioedema, hereditary angioedema (HAE) and acquired angioedema (AAE), result from deficiency or dysfunction of C1 esterase inhibitor, leading to an overproduction of bradykinin, which can lead to vascular permeability and life-threatening angioedema of the airway. The objective of this study was to review perioperative outcomes in a series of patients with HAE and AAE and to review current knowledge about anesthetic complications in patients with HAE or AAE...

A 62-year-old man with a left temporal lobe tumor was scheduled for a semiurgent craniotomy for tumor excision. Previously, the patient had a laryngeal carcinoma that was resected and treated with chemotherapy and radiotherapy and a history of laryngeal biopsy with awake fiberoptic intubation. Because a difficult airway was anticipated, awake fiberoptic nasopharyngoscopy of the airway was performed under topical anesthesia in the operating room. This revealed a narrow glottic opening with no supraglottic pathology or friable tissue...

We present the case report of a 49-year-old gentleman with a history of adenoid cystic carcinoma of the left nare status post curative bifrontal craniotomy, left lateral rhinotomy and medial maxillectomy, adjuvant radiotherapy, and orbital exenteration for optic neuropathy, complicated by medial wall dehiscence. His course was also complicated by severe radiation trismus, for which he was scheduled to undergo bilateral mandibular coronoidectomies. Given his limited mouth opening, the surgeon requested a nasal endotracheal tube...

The Fourth National Audit Project (NAP4) recommended airway training for trainee and trained anaesthetists. As the skills required for management of airway emergencies differ from routine skills and these events are rare, practical training is likely to require training workshops. In 2013, we surveyed all UK National Health Service hospitals to examine the current practices regarding airway training workshops. We received responses from 206 hospitals (62%) covering all regions. Regarding airway workshops, 16% provide none and 51% only for trainees...

We compared the Bonfils(™) and SensaScope(™) rigid fibreoptic scopes in 200 patients with a simulated difficult airway randomised to one of the two devices. A cervical collar inhibited neck movement and reduced mouth opening to a mean (SD) of 23 (3) mm. The primary outcome parameter was overall success of tracheal intubation; secondary outcomes included first-attempt success, intubation times, difficulty of intubation, fibreoptic view and side-effects. The mean (95% CI) overall success rate was 88 (80-94)% for the Bonfils and 89 (81-94)% for the SensaScope (p = 0...

BACKGROUND AND OBJECTIVES: Managing the airway of post burn contracture of the neck has always been challenging to anesthesiologists as it limits the alignment of oro-pharyngo-laryngeal axes because of functional and anatomical deformities that occur as a result of long standing contractures. Here the role of the King Vision video laryngoscope which is the latest in the series of video laryngoscope has been evaluated for such patients. CASE REPORT: A 35 year old male patient with post burn contracture of neck was scheduled for release of the contracture...

INTRODUCTION: Scleroderma is a progressive fibrotic disorder of connective tissue which can present multiple anesthetic challenges to anesthetists, especially airway management. Awake intubation with fiberoptic bronchoscope is widely accepted and implemented for progressive systematic scleroderma patients. With the development and improvement of intubation devices these years, there is no report addressing other intubation methods for sclerotic patients. CASE DESCRIPTION: A 47 year-old, 42-kg man with 1-year history of localized scleroderma was scheduled for the operation of inner fixation after 6 days of his acetabular fracture...
