A trachea is a tubular structure composed of smooth muscle that is reinforced with cartilage rings. Some diseases can cause sagging in smooth muscle and cartilaginous tissue. The end result is reduction (narrowing) of the trachea diameter. A solution to this problem is the use of tracheal stents, which are small tubular devices made of silicone. One is inserted into the trachea to prevent or correct its constriction. The purpose of tracheal stent use is to maintain cartilage support that would otherwise be lost in the airway...

The difficult airway constitutes a continuous challenge for anesthesiologists. Guidelines and algorithms are key to preserving patient safety, by recommending specific plans and strategies that address predicted or unexpected difficult airway. However, there are currently no "gold standard" algorithms or universally accepted standards. The aim of this article is to present a synthesis of the recommendations of the main guidelines and difficult airway algorithms.

Ultrasound has become a rapid, safe, and easy-to-use tool for anesthesiologists. It reduces complications, morbidity, and mortality, especially in patients with anatomic abnormalities in whom a traditional approach may be both difficult and risky. We report 2 cases of symptomatic patients with a difficult airway due to displacement of the trachea by a neck mass. Real-time ultrasound imaging was performed for percutaneous dilatational tracheostomies, identifying important structures, without any complications...

BACKGROUND: Swallowing is a systematic process. Any structural, physiological or neurological disturbance in this process may cause dysphagia. Although there are studies that report head/neck movements during mastication, there are fewer studies that show the effect of different head/neck postures on difficulty while swallowing. OBJECTIVES: To observe the effect of different body postures on the self-perceived difficulty while swallowing in normal healthy subjects...

BACKGROUND: Mechanical ventilation after general surgery is associated with worse outcomes, prolonged hospital stay, and increased health care cost. Postoperatively, patients admitted to the intensive care unit (ICU) may be categorized into 1 of 3 groups: extubated patients (EXT), patients with objective medical indications to remain ventilated (MED), and patients not meeting these criteria, called "discretional postoperative mechanical ventilation" (DPMV). The objectives of this study were to determine the incidence of DPMV in general surgery patients and identify the associated operative factors...

The management of difficult airway (DA) in thoracic surgery is more difficult due to the need for lung separation or isolation and frequent presence of associated upper and lower airway problems. We performed an article review analysing 818 papers published with clinical evidence indexed in Pubmed that allowed us to develop an algorithm. The best airway management in predicted DA is tracheal intubation and independent bronchial blockers guided by fibroscopy maintaining spontaneous ventilation. For unpredicted DA, the use of videolaryngoscopes is recommended initially, and adequate neuromuscular relaxation (rocuronium/sugammadex), among other maneuvers...

BACKGROUND: Airway epithelial cells (AEC) are quite difficult to access in newborns and infants. It is critically important to develop robust life-extended models to conduct translational studies in this age group. We propose the use of a recently described cell-culture technology (conditionally reprogrammed cells - CRC) to generate continuous primary cell cultures from nasal and bronchial AEC of young children. METHODS: We collected nasal and/or bronchial AEC from a total of 23 subjects of different ages including newborns/infants/toddlers (0-2 years; N=9), school age children (4-11 years; N=6), and a group of adolescent/adult donors (N=8)...

STUDY OBJECTIVE: Video laryngoscopy has primarily been developed to assist in difficult airways. Using video laryngoscopy in pediatric airway management is an up-and-coming topic. The aim of the presented study was to compare the intubation conditions obtained when using the C-MAC video laryngoscope with Miller blades sizes 0 and 1 for standard direct laryngoscopy and indirect laryngoscopy in children weighing less than 10 kg. DESIGN: This was a prospective study...

BACKGROUND: One of the main challenges in anesthesiology is difficult intubation. There are many anatomical parameters for evaluating the feasibility of tracheal intubation; one that can reliably predict a difficult intubation is the Cormack-Lehane classification obtained during direct laryngoscopy. This is an invasive procedure that cannot be performed in an awake patient or for pre-anesthetic airway assessments in patients with no prior history of tracheal intubation. Recently, ultrasound has been successfully used for several airway-related applications...

A retropharyngeal mass may distort the airway anatomy and reduce the space available for manipulation of intubation devices. We encountered a patient with a cervical chordoma occupying the retropharyngeal space. Fiber-optic orotracheal intubation was attempted to secure the airway. Although the fiber-optic bronchoscope (FOB) was successfully placed into the trachea, the tracheal tube could not be passed through the glottis. An airway was then successfully established with the Trachway device, a video-assisted system with a rigid but malleable intubating stylet...

INTRODUCTION: Noninvasive ventilation (NIV) has been widely used to treat acute respiratory failure in obese patients. Criteria that could help clinicians to decide whether they should continue to use NIV after such an initial episode remain unclear. Our retrospective study aims to analyze characteristics of subjects receiving long-term NIV after an initial hospitalization for acute respiratory failure. METHODS: From January 2011 to December 2012, 77 obese adults were admitted in the ICU of the respiratory disease department in Nantes University Hospital in France...

BACKGROUND: When encountering a difficult airway with an Airway Scope (AWS) a bougie can be inserted into the endotracheal tube in the AWS channel. The angulated tip of the bougie can be guided toward the glottis by rotating it. We tested the ease of rotating bougies (Venn reusable, Boussignac, Portex single-use, and Frova) in an endotracheal tube when placed in the AWS channel. METHODS: Bench study: Seven anesthesiologists inserted each of the four types of bougies into a 7...

Difficulties with tracheal intubation commonly arise and impact patient safety. This systematic review evaluates whether videolaryngoscopes reduce intubation failure and complications compared with direct laryngoscopy in adults. We searched CENTRAL, MEDLINE, Embase and clinicaltrials.gov up to February 2015, and conducted forward and backward citation tracking. We included randomized controlled trials that compared adult patients undergoing laryngoscopy with videolaryngoscopy or Macintosh laryngoscopy. We did not primarily intend to compare individual videolaryngoscopes...

Tracheal intubation via laryngeal exposure has evolved over the past 150 years and has greatly expanded in the last decade with the introduction and development of newer, more sophisticated optical airway devices. The introduction of indirect and video-assisted laryngoscopes has significantly impacted airway management as evidenced by the presence of these devices in the majority of published difficult airway algorithms. However, it is quite possible that many airway managers do not have a thorough comprehension of how these devices actually function, an understanding that is vital not only for their use but also for assessing the devices' limitations...

An emergency surgical airway is a lifesaving intervention required in the event of airway loss or respiratory failure when conventional endotracheal intubation cannot be performed. The Acute Care Surgery/Trauma Service is a critical component in the angioedema/difficult airway protocol at our institution. We conducted a retrospective review (2007-2016) to analyze the role our service has in managing patients requiring an emergency surgical airway. Cases were analyzed for preexisting conditions, hospital location of procedure, techniques, complications, and mortality...

PURPOSE OF REVIEW: Successful and sustainable training and learning of the management of difficult and normal airway is essential for all clinically active anesthesiologists. We emphasize the importance of a continuously updated learning and training environment based on actual knowledge, best available equipment, standardized procedures, and educational theory. RECENT FINDINGS: In the past, most of the training were based on 'learning by doing' under the supervision of superiors or experienced colleagues...

Anterior laryngeal web is a rare anomaly which is usually asymptomatic in infancy. This translates into a high incidence of unanticipated difficult intubation in these patients with consequent airway morbidity in the form of tracheostomy. We are reporting a case of unsuspected difficult intubation in a neonate due to the presence of a congenital anterior laryngeal web. After multiple failed intubation attempts with direct laryngoscopy, use of CMAC video laryngoscope improved the glottic view, enabled us to diagnose the presence of a thick anterior laryngeal web and intubate the child...

BACKGROUND: Immobilization of the cervical spine is indicated in all patients with the potential risk of any cervical spine injury. Airway management in these patients is challenging and direct laryngoscopy is the standard of care. Videolaryngoscopes like the ET-View were introduced into clinical practice to provide better airway visualization and ease intubation. The ET-View is essentially a conventional endotracheal tube, but is equipped with a miniature camera on the tip. The ET-View has not been investigated in patients with immobilized cervical spine so far...
